Methods: This was a descriptive cross-sectional study with prospective data collection in the maternity wards of the Yaoundé Gynaeco-Obstetric and Paediatric Hospital, and the Yaoundé Central Hospital for 7 months, from the 1st of November 2022 to the 31st of May 2023. The variables studied were demographic and clinical characteristics, means of recourse and post-abortion contraception. The frequency of abortions was calculated as the ratio of the number of abortions to the number of deliveries. The calculation of numbers and frequencies was used to describe the study population, and to highlight the sociodemographic and clinical characteristics of the patients recruited. Quantitative variables were expressed as mean ± standard deviation. Data were collected numerically and classified according to type, then analyzed using Epi-info version 7.2 software. Microsoft Office Excel 2013 was used to produce figures and tables. Results: During the study period, 169 patients were selected out of 1882 patients who had consulted for gynaecological emergencies;but only 164 of them accepted to participate. The frequency of abortions was 9.6% (169/1882). The age group of 25 to 29 years was the most represented, with 29.3% (48/164). They were mainly single 76.2% (125/164), and housewives 33.5% (55/164). The notion of previous abortion was found in 30.5% (50/164) of them. Approximately 19.5% of patients (32/164) reported to have conceived while using contraception, 56.2% of whom (18/32) used male condoms. At the time of admission to the emergency unit, the predominant symptom was bleeding in 70.7% of cases. The abortions were mainly spontaneous, in 75% of cases (123/164). In cases of induced abortions, 24.4% (10/41) of them took place after 14 weeks. Unexpected pregnancy was the main reason for termination in 46.3% of cases (19/41). Regarding induced abortion, 58.54% (24/41) of them resorted to voluntary medical termination. The mortality rate was 1.2%. The acceptability rate of a modern contraceptive method before discharge was 31.7%. Conclusion: Although frequent in our environment, data relating to abortion remain under-evaluated. Abortions occur mainly among young, single women, with a still very high proportion of induced abortions. The acceptability of post-abortion contraception remains poor. Prevention of unwanted pregnancies and risk factors is necessary to reduce the burden of abortions in low-income countries.展开更多

METHODS:Sixty-nine ulcerative colitis patients (39 F,30 M) dependent upon/refractory to steroids were treated with GMA. Steroid dependency,clinical activity index (CAI),C reactive protein (CRP) level,erythrocyte sedimentation rate (ESR),values at baseline,use of immunosuppressant,duration of disease,and age and extent of disease were considered for statistical analysis as predictive factors of clinical response. Univariate and multivariate logistic regression models were used. RESULTS:In the univariate analysis,CAI (P = 0.039) and ESR (P = 0.017) levels at baseline were singled out as predictive of clinical remission. In the multivariate analysis steroid dependency [Odds ratio (OR) = 0.390,95% Confidence interval (CI):0.176-0.865,Wald 5.361,P = 0.0160] and low CAI levels at baseline (4 < CAI <7) (OR = 0.770,95% CI:0.425-1.394,Wald 3.747,P = 0.028) proved to be effective as factors predicting clinical response. CONCLUSION:GMA may be a valid therapeutic option for steroid-dependent ulcerative colitis patients with mild-moderate disease and its clinical efficacy seems to persist for 12 mo.展开更多

Methods: Cows with clinical endometritis Ⅲ (n=399) were aligned into three groups randomly. The first group (n=115) received PGF2α, the second group (n=84) received intrauterine infusion (IUI) of oxytetracycline 10% + PGF2α, and the third group (n=200) received IUI. Cows were inseminated following estrus. The pregnancy status, parity, calving and artificial insemination season, ovaries with corpus luteum at the time of treatment, dystocia, body condition score and treatment groups were included in data analysis. Results: Total pregnancy rate was 40.1% after the first insemination and 94.2% after the third insemination. Overall pregnancy rate of treated cows with IUI+PGF2α(84.5%) was significantly lower than the treated cows with PGF2α(98.3%) or IUI (96%) (P<0.05). The first service pregnancy rate of inseminated cows in summer (14.3%) was lower in comparison with cows inseminated in spring (40.4%), fall (41.4%) and winter (51.7%) (P<0.05). Conclusions: PGF2α could treat severe clinical endometritis in dairy cows with corpus luteum in comparison with other treatments.展开更多

Its recognition is, therefore, a "window opportunity" to prevent a coronary event by aggressive treatment of cardiovascular risk factors. The artery size hypothesis (ASH) has been proposed as a putative mechanism to explain the relationship between ED and CAD. Since atherosclerosis is a systemic disorder all major vascular beds should be affected to the same extent. However, symptoms at different points in the system rarely become evident at the same time. This is likely the result of smaller vessels (i.e. the penile artery) being able to less well tolerate the same amount of plaque when compared with larger ones (i.e. the coronary artery). If true, ED will develop before CAD. We present a case in which ED developed after a coronary event yet before a coronary recurrence potentially representing a late marker of vascular progression. Reasons for this unusual sequence are discussed as they might still fit the ASH.展开更多

In the west, it is the 3rd most common cause of death. In addition to that, it is a disturbing and restricting cerebrovascular disease with a substantial amount of remaining shortage leading on to emotional and financial burden on the family and society. A hospital-based retrospective study was conducted at Teaching Hospital Batticaloa, Sri Lanka from July 1, 2016, to October 31, 2016. During the study period, data were collected from the medical records. Out of 34 patients, 21 (61.8%) were males and 13 (38.2%) were females. The male to female ratio was 1.6:1. Out of 34 patients, 17 (50%) were affected in the left side and 17 (50%) were affected on the right side. The most common risk factor was hypertension with 79.4%, and next to that diabetes mellitus (41.2%), smoking (23.5%), alcohol (20.6%), past history of Stroke (17.6%) and ischaemic heart disease (IHD) (14.7%). Stroke due to infarction is more common than haemorrhage. In this study, both right and left sides were affected equally. In order to prevent this devastating stroke, acknowledgment of risk factors for stroke is prime importance for the healthcare workers as well as public.展开更多

Uropathogenic E. coli (UPEC) has been shown to have a pathogenicity island that enables them to infect the urinary tract. Because there is little information about the presence of UPEC-associated virulent genes in animal isolates this work was carried out with the intent to enhance the understanding about the strains of E.coli that cause infections in animals. Results: We screened 21 E. coli strains isolated causing urinary tract infection in domestic animals. Primers were designed to amplify urinary infection-associated genes. Nine genes, papA, tcpC, fyuA, tpbA, Lma, hylA, picU, tonB, and flicC were then amplified and sequenced. Different from the human isolate CFT073, all the animals E. coli lack some of the pathogenesis-associated genes. Genes encoding for proteins used to scavenge iron appear not to be so necessary during animal infections as they are in human infection. In further investigation of phenotypic properties, it was observed that animal UPECs have significantly more impaired ability to form biofilms than human UPEC strain. Conclusions: This study identified significant differences between human and animal UPECs. This may have its roots in the fact that it is difficult to determine if an animal has symptoms. Future studies will focus on some of the observations.展开更多

The present study was conducted with the aim to compare the effects of creative group teaching and educational booklet on interpersonal skills of midwives in a clinical setting. The present study was conducted on 97 midwifery graduates working in hospitals in Kerman Province, in two groups of educational booklet (49 midwives) and educational workshop (48 midwives) who participated in a 3-day creative teaching workshop in summer 2015. Creative problem-solving teaching intervention group was taught through educational workshop method, including small group and team working, group discussion and mini lectures. Midwifery 1 intervention group was provided with an educational booklet validated by professors of Nursing and Midwifery School for independent and individual study by midwives working in Kerman Province hospitals. The two groups were matched in terms of personal details. Hospitals were randomly selected, and midwives were selected by quota sampling. Interpersonal communication skills of both groups were assessed before and after intervention, and two months later using Interpersonal Communication Skills Test. The results obtained were analyzed in SPSS-16 using descriptive statistics, including frequency and percentage, mean and standard deviation, and inferential statistics including U-Mann-Whitney, paired t, independent t, repeated measures ANOVA tests at significance level of P P P P P < 0.001). Both teaching methods improved midwives’ interpersonal communication skills. Therefore, standardized educational booklets which produce cost-effective similar results are recommended.展开更多

In Senegal, few studies have described the epidemiology of ARF in the elderly. The aim of our study is to establish the epidemiological profile of elderly patients with ARF, identify the causes of ARF in the elderly and assess treatment and prognosis. Methods: We conducted a descriptive and retrospective study over a five-year period from 2011 to 2015 involving patients aged 60 and over, treated for ARI during the study period. Data entry and analysis were done on Epi info 7.3. Results: We included a total of 45 patients. The prevalence of ARF was 3.34%. The mean age was 70.31 years (60 - 83) and the sex ratio was 3.5. Phytotherapy was found in 68.9%, hypertension was found in 68.9%, and diabetes was found in 31.1%. Prostate hypertrophy was found in 53.4% of patients. Pre-renal ARF was the most common (46.6%). Most of the cases, 66.67%, were at Stage 3 of KDIGO. The most common etiologies were respectively tumor (35.5%) and infection (20%). The most common complications were respectively hyperkalemia (33.3%) and hyponatremia (33.3%). Recovery was complete in 62.6% of cases, partial in 37.8% of patients and 13.3% of patients ended up on chronic hemodialysis. Mortality was 4.4%. Conclusion: Herbal medicine, hypertension and diabetes are frequently associated with ARF in the elderly. This justifies increased monitoring of the elderly subject with these conditions in order to subject him to early and appropriate care.展开更多

These complications should be known and recognized, as they require urgent treatment with intravenous antibiotics and close in-hospital monitoring. In this study, we aimed to identify the main risk factors associated with the development of complications in children aged 2 - 17 years with ABRS. Methods: We conducted a retrospective cohort study of patients with ABRS complications in a primary hospital. Participants were divided into two groups: the control group comprising patients without complications (Group 1, n = 82) and the study group comprising patients with complications requiring hospitalization (Group 2, n = 41). We assessed the sociodemographic, clinical, and imaging data of both groups. Using multivariate logistic regression, we assessed risk factors of ABRS complications. Results: No socio-demographic characteristics were associated with ABRS complications (p ≥ 0.05). Factors associated with complications were delay in consultation (t = 5.282;p Conclusions: Intracranial and extracranial complications of ABRS in children have become rare in our setting. These complications can be serious and potentially fatal. Risk factors of these complications are delays in consultation, the presence of ophthalmological signs, and more than one affected sinus. Controlling modifiable factors would improve the treatment success of ABRS complications in children.展开更多

文摘Abortion is one of the leading causes of maternal death in Cameroon, despite numerous policies and strategies put in place to reduce it by 2030.This study aims to describe the epidemiologic aspects of abortions within hospitals in the city of Yaoundé in 2023. Methods: This was a descriptive cross-sectional study with prospective data collection in the maternity wards of the Yaoundé Gynaeco-Obstetric and Paediatric Hospital, and the Yaoundé Central Hospital for 7 months, from the 1st of November 2022 to the 31st of May 2023. The variables studied were demographic and clinical characteristics, means of recourse and post-abortion contraception. The frequency of abortions was calculated as the ratio of the number of abortions to the number of deliveries. The calculation of numbers and frequencies was used to describe the study population, and to highlight the sociodemographic and clinical characteristics of the patients recruited. Quantitative variables were expressed as mean ± standard deviation. Data were collected numerically and classified according to type, then analyzed using Epi-info version 7.2 software. Microsoft Office Excel 2013 was used to produce figures and tables. Results: During the study period, 169 patients were selected out of 1882 patients who had consulted for gynaecological emergencies;but only 164 of them accepted to participate. The frequency of abortions was 9.6% (169/1882). The age group of 25 to 29 years was the most represented, with 29.3% (48/164). They were mainly single 76.2% (125/164), and housewives 33.5% (55/164). The notion of previous abortion was found in 30.5% (50/164) of them. Approximately 19.5% of patients (32/164) reported to have conceived while using contraception, 56.2% of whom (18/32) used male condoms. At the time of admission to the emergency unit, the predominant symptom was bleeding in 70.7% of cases. The abortions were mainly spontaneous, in 75% of cases (123/164). In cases of induced abortions, 24.4% (10/41) of them took place after 14 weeks. Unexpected pregnancy was the main reason for termination in 46.3% of cases (19/41). Regarding induced abortion, 58.54% (24/41) of them resorted to voluntary medical termination. The mortality rate was 1.2%. The acceptability rate of a modern contraceptive method before discharge was 31.7%. Conclusion: Although frequent in our environment, data relating to abortion remain under-evaluated. Abortions occur mainly among young, single women, with a still very high proportion of induced abortions. The acceptability of post-abortion contraception remains poor. Prevention of unwanted pregnancies and risk factors is necessary to reduce the burden of abortions in low-income countries.
文摘Background:Mastitis caused by different pathogens including Streptococcus uberis(S.uberis)is responsible for huge economic losses to the dairy industry.In order to investigate the potential genetic and epigenetic regulatory mecha‑nisms of subclinical mastitis due to S.uberis,the DNA methylome(whole genome DNA methylation sequencing)and transcriptome(RNA sequencing)of milk somatic cells from cows with naturally occurring S.uberis subclinical mastitis and healthy control cows(n=3/group)were studied.Results:Globally,the DNA methylation levels of CpG sites were low in the promoters and first exons but high in inner exons and introns.The DNA methylation levels at the promoter,first exon and first intron regions were nega‑tively correlated with the expression level of genes at a whole‑genome‑wide scale.In general,DNA methylation level was lower in S.uberis‑positive group(SUG)than in the control group(CTG).A total of 174,342 differentially methylated cytosines(DMCs)(FDR<0.05)were identified between SUG and CTG,including 132,237,7412 and 34,693 DMCs in the context of CpG,CHG and CHH(H=A or T or C),respectively.Besides,101,612 methylation haplotype blocks(MHBs)were identified,including 451 MHBs that were significantly different(dMHB)between the two groups.A total of 2130 differentially expressed(DE)genes(1378 with up‑regulated and 752 with down‑regulated expression)were found in SUG.Integration of methylome and transcriptome data with MethGET program revealed 1623 genes with signifi‑cant changes in their methylation levels and/or gene expression changes(MetGDE genes,MethGET P‑value<0.001).Functional enrichment of genes harboring≥15 DMCs,DE genes and MetGDE genes suggest significant involvement of DNA methylation changes in the regulation of the host immune response to S.uberis infection,especially cytokine activities.Furthermore,discriminant correlation analysis with DIABLO method identified 26 candidate biomarkers,including 6 DE genes,15 CpG‑DMCs and 5 dMHBs that discriminated between SUG and CTG.Conclusion:The integration of methylome and transcriptome of milk somatic cells suggests the possible involve‑ment of DNA methylation changes in the regulation of the host immune response to subclinical mastitis due to S.uberis.The presented genetic and epigenetic biomarkers could contribute to the design of management strategies of subclinical mastitis and breeding for mastitis resistance.
文摘AIM:To identify factors predicting the clinical response of ulcerative colitis patients to granulocyte-monocyte apheresis (GMA). METHODS:Sixty-nine ulcerative colitis patients (39 F,30 M) dependent upon/refractory to steroids were treated with GMA. Steroid dependency,clinical activity index (CAI),C reactive protein (CRP) level,erythrocyte sedimentation rate (ESR),values at baseline,use of immunosuppressant,duration of disease,and age and extent of disease were considered for statistical analysis as predictive factors of clinical response. Univariate and multivariate logistic regression models were used. RESULTS:In the univariate analysis,CAI (P = 0.039) and ESR (P = 0.017) levels at baseline were singled out as predictive of clinical remission. In the multivariate analysis steroid dependency [Odds ratio (OR) = 0.390,95% Confidence interval (CI):0.176-0.865,Wald 5.361,P = 0.0160] and low CAI levels at baseline (4 < CAI <7) (OR = 0.770,95% CI:0.425-1.394,Wald 3.747,P = 0.028) proved to be effective as factors predicting clinical response. CONCLUSION:GMA may be a valid therapeutic option for steroid-dependent ulcerative colitis patients with mild-moderate disease and its clinical efficacy seems to persist for 12 mo.
文摘A 3-year-old Persian queen was referred to Teaching Veterinary Hospital while 3 neonates' umbilical cords were entangled with the queen's tail hair.Close inspection of the cat showed that the umbilical cords of 3 kittens had twisted around together and entangled with the moms' hairs in the base of tail region.Also this complex has been warped around the left tarsus of one of the involved kittens and caused swelling and skin darkness in the involved limb.Operation was carried out urgently.After cutting the queen's involved hairs the kittens were released.Then the twisted umbilical cords and the hairs were isolated from the umbilical cord and the involved leg was released from the umbilical cords and the twisted umbilical cords were separated from each other.During one week follow up,dry gangrene occurred in the distal extremity of the injured limb and consequently,amputation was performed on the distal part of tibia.Our clinical findings suggest that long hair coats of queens could be a maternal life threatening factor for neonates' life.

文摘Objective:To investigate clinical,pathological and mycological findings in canaries,in which pox lesions and Aspergillus fumigatus(A.fumigatus)infection were observed simultaneously.Methods:This study was performed on a breeding colony(about 100 canaries)affected by fatal wasting disease.Necropsy was undertaken on 10 severely affected canaries,and gross lesions were recorded.Samples from internal organs displaying lesions were obtained for histopathological evaluation.Tracheal swap samples of internal organs of the all infected animals with lesions at necropsy were cultured in Sabouraud Dextrose Agar for mycological examination.Results:At necropsy,caseous foci were determined in the lungs,on the air sacs,liver,spleen,heart.Swelling of the eyelids,diffuse hemorrhages in the subcutaneous tissue with small papular lesions of the skin were other typical necropsy findings.Histopathologically,pathognomonic eosinophilic intracytoplasmic inclusion bodies,which called Bollinger bodies,in both skin cells and vacuolated air way epithelial cells confirmed canary pox infection.Moreover,histopathological examination of the white-yellowish caseous foci revealed necrotic granulomatous reaction consisting of macrophages,heterophil leukocytes and giant cells encapsulated with a fibrous tissue.After the culture of the tissue samples,the formation of bluish green colonies confirmed A.fumigatus infection.Conclusions:Canary pox has been known as the disease that can result in high losses in a short time,as a re-emerging disease that has not been present during recent years in canary flocks in Iran.So,the current paper provides useful information to prevent misdiagnosed of canary pox disease which can cause secondary mycotic infection.
文摘Objective: To confirm the efficacy of non-antibiotic treatment with prostaglandin F2α(PGF2α) in dairy cows affected by severe clinical endometritis in (30±3) days in milk. Methods: Cows with clinical endometritis Ⅲ (n=399) were aligned into three groups randomly. The first group (n=115) received PGF2α, the second group (n=84) received intrauterine infusion (IUI) of oxytetracycline 10% + PGF2α, and the third group (n=200) received IUI. Cows were inseminated following estrus. The pregnancy status, parity, calving and artificial insemination season, ovaries with corpus luteum at the time of treatment, dystocia, body condition score and treatment groups were included in data analysis. Results: Total pregnancy rate was 40.1% after the first insemination and 94.2% after the third insemination. Overall pregnancy rate of treated cows with IUI+PGF2α(84.5%) was significantly lower than the treated cows with PGF2α(98.3%) or IUI (96%) (P<0.05). The first service pregnancy rate of inseminated cows in summer (14.3%) was lower in comparison with cows inseminated in spring (40.4%), fall (41.4%) and winter (51.7%) (P<0.05). Conclusions: PGF2α could treat severe clinical endometritis in dairy cows with corpus luteum in comparison with other treatments.
文摘Erectile dysfunction (ED) has been found to frequently precedes the onset of coronary artery disease (CAD), representing an early marker of subclinical vascular disease, included CAD. Its recognition is, therefore, a "window opportunity" to prevent a coronary event by aggressive treatment of cardiovascular risk factors. The artery size hypothesis (ASH) has been proposed as a putative mechanism to explain the relationship between ED and CAD. Since atherosclerosis is a systemic disorder all major vascular beds should be affected to the same extent. However, symptoms at different points in the system rarely become evident at the same time. This is likely the result of smaller vessels (i.e. the penile artery) being able to less well tolerate the same amount of plaque when compared with larger ones (i.e. the coronary artery). If true, ED will develop before CAD. We present a case in which ED developed after a coronary event yet before a coronary recurrence potentially representing a late marker of vascular progression. Reasons for this unusual sequence are discussed as they might still fit the ASH.
文摘Stroke as a disease entity has significantly increased the morbidity, incapacity, and mortality in Sri Lanka. In the west, it is the 3rd most common cause of death. In addition to that, it is a disturbing and restricting cerebrovascular disease with a substantial amount of remaining shortage leading on to emotional and financial burden on the family and society. A hospital-based retrospective study was conducted at Teaching Hospital Batticaloa, Sri Lanka from July 1, 2016, to October 31, 2016. During the study period, data were collected from the medical records. Out of 34 patients, 21 (61.8%) were males and 13 (38.2%) were females. The male to female ratio was 1.6:1. Out of 34 patients, 17 (50%) were affected in the left side and 17 (50%) were affected on the right side. The most common risk factor was hypertension with 79.4%, and next to that diabetes mellitus (41.2%), smoking (23.5%), alcohol (20.6%), past history of Stroke (17.6%) and ischaemic heart disease (IHD) (14.7%). Stroke due to infarction is more common than haemorrhage. In this study, both right and left sides were affected equally. In order to prevent this devastating stroke, acknowledgment of risk factors for stroke is prime importance for the healthcare workers as well as public.
文摘Background: Urinary tract infection caused by Escherichia coli is a frequently observed condition both in humans and animals. Uropathogenic E. coli (UPEC) has been shown to have a pathogenicity island that enables them to infect the urinary tract. Because there is little information about the presence of UPEC-associated virulent genes in animal isolates this work was carried out with the intent to enhance the understanding about the strains of E.coli that cause infections in animals. Results: We screened 21 E. coli strains isolated causing urinary tract infection in domestic animals. Primers were designed to amplify urinary infection-associated genes. Nine genes, papA, tcpC, fyuA, tpbA, Lma, hylA, picU, tonB, and flicC were then amplified and sequenced. Different from the human isolate CFT073, all the animals E. coli lack some of the pathogenesis-associated genes. Genes encoding for proteins used to scavenge iron appear not to be so necessary during animal infections as they are in human infection. In further investigation of phenotypic properties, it was observed that animal UPECs have significantly more impaired ability to form biofilms than human UPEC strain. Conclusions: This study identified significant differences between human and animal UPECs. This may have its roots in the fact that it is difficult to determine if an animal has symptoms. Future studies will focus on some of the observations.

文摘Group discussion teaching technique for small groups and encouragement of critical but constructive and creative thinking for finding new and efficient solutions can lead to provision of better health and medical services that is defined in clinical setting, as the clinical psychology finds a way for curing and education. The present study was conducted with the aim to compare the effects of creative group teaching and educational booklet on interpersonal skills of midwives in a clinical setting. The present study was conducted on 97 midwifery graduates working in hospitals in Kerman Province, in two groups of educational booklet (49 midwives) and educational workshop (48 midwives) who participated in a 3-day creative teaching workshop in summer 2015. Creative problem-solving teaching intervention group was taught through educational workshop method, including small group and team working, group discussion and mini lectures. Midwifery 1 intervention group was provided with an educational booklet validated by professors of Nursing and Midwifery School for independent and individual study by midwives working in Kerman Province hospitals. The two groups were matched in terms of personal details. Hospitals were randomly selected, and midwives were selected by quota sampling. Interpersonal communication skills of both groups were assessed before and after intervention, and two months later using Interpersonal Communication Skills Test. The results obtained were analyzed in SPSS-16 using descriptive statistics, including frequency and percentage, mean and standard deviation, and inferential statistics including U-Mann-Whitney, paired t, independent t, repeated measures ANOVA tests at significance level of P P P P P < 0.001). Both teaching methods improved midwives’ interpersonal communication skills. Therefore, standardized educational booklets which produce cost-effective similar results are recommended.
文摘Introduction: The incidence of acute renal failure (ARF) increases with age. In Senegal, few studies have described the epidemiology of ARF in the elderly. The aim of our study is to establish the epidemiological profile of elderly patients with ARF, identify the causes of ARF in the elderly and assess treatment and prognosis. Methods: We conducted a descriptive and retrospective study over a five-year period from 2011 to 2015 involving patients aged 60 and over, treated for ARI during the study period. Data entry and analysis were done on Epi info 7.3. Results: We included a total of 45 patients. The prevalence of ARF was 3.34%. The mean age was 70.31 years (60 - 83) and the sex ratio was 3.5. Phytotherapy was found in 68.9%, hypertension was found in 68.9%, and diabetes was found in 31.1%. Prostate hypertrophy was found in 53.4% of patients. Pre-renal ARF was the most common (46.6%). Most of the cases, 66.67%, were at Stage 3 of KDIGO. The most common etiologies were respectively tumor (35.5%) and infection (20%). The most common complications were respectively hyperkalemia (33.3%) and hyponatremia (33.3%). Recovery was complete in 62.6% of cases, partial in 37.8% of patients and 13.3% of patients ended up on chronic hemodialysis. Mortality was 4.4%. Conclusion: Herbal medicine, hypertension and diabetes are frequently associated with ARF in the elderly. This justifies increased monitoring of the elderly subject with these conditions in order to subject him to early and appropriate care.
文摘Objective To evaluate the association of GGN repeat polymorphism of androgen receptor(AR)with ovarian reserve and ovarian response in controlled ovarian stimulation(COS).Methods This genetic association study was conducted among a total of 361 women aged≤40 years with basal FSH≤12 U/L undergoing the GnRH-agonist long protocol for COS in a university affiliated IVF center.GGN repeat in the AR gene was analyzed with Sanger sequencing.The primary endpoint was the number of antral follicle counts(AFCs),and the secondary endpoints were stimulation days,total dose of gonadotropin(Gn)used,total number of retrieved oocytes,ovarian sensitivity index,and follicular output rate.Results The GGN repeat in exon 1 of the AR gene ranged from 13 to 24,and the median repeat length was 22.Based on the genotypes(S for GGN repeats<22,L for GGN repeats≥22),the patients were divided into 3 groups:SS,SL,and LL.Generalized regression analysis indicated that the number of AFCs in group SS was significantly lower than those in group SL(adjusted β=1.8,95%CI:0.2-3.4,P=0.024)and group LL(adjusted β=1.5,95%CI:0.2-2.7,P=0.021).No significant difference was observed in the number of AFCs between group SL and group LL(P>0.05).Generalized regression analysis indicated no significant differences in ovarian stimulation parameters among the 3 groups,either before or after adjusting for confounding factors(P>0.05).Conclusion GGN repeat length on the AR gene is associated with AFC but not with ovarian response in Chinese women,indicating that AR gene polymorphisms may affect ovarian reserve.
文摘Insulin resistance(IR)is widely recognized as a key contributor to metabolic disorders,and various surrogate indices have been developed to estimate IR in clinical and research settings.The hyperinsulinemic-euglycemic clamp is considered the gold standard method for assessing insulin resistance due to its precision;however,its complexity limits its widespread clinical application.Consequently,surrogate indices derived from fasting and post-load glucose and insulin levels have been developed to estimate IR,facilitating early detection and risk stratification in metabolic disorders.This mini-review discusses the clinical utility,strengths,and limitations of key IR indices,including the homeostasis model assessment of IR,quantitative insulin sensitivity check index,Matsuda index,and triglyceride-glucose index.Overall,the evidence presented to date suggests that these indices provide valuable estimates of IR in various popula-tions.Yet,their applicability varies depending on ethnic background,disease status,and clinical setting.Integrating these indices into routine clinical practice and research could improve metabolic risk assessment and guide preventive interventions.Further investigations are necessary to refine their accuracy and determine optimal cut-off values for various populations.
文摘Portal hypertension(PH)is a major complication of chronic liver disease,often leading to serious clinical consequences such as variceal bleeding,ascites,and splenomegaly.The current gold standard for PH diagnosis,namely,hepatic venous pressure gradient measurement,is invasive and not widely available.Transient elastography has emerged as a non-invasive alternative for assessing liver stiffness(LS),and recent studies have highlighted the potential role of splenic stiffness(SS)in evaluating PH severity.This narrative review summarizes the available evidence on the utility of splenic transient elastography in assessing PH.We evaluated its diagnostic accuracy,technical challenges,and clinical applications,particularly in distinguishing between cirrhotic PH(CPH)and noncirrhotic PH(NCPH).A comprehensive literature search was conducted using the PubMed database,focusing on studies that assess splenic elastography in the diagnosis and prognosis of PH.This review compares splenic elastography with other non-invasive imaging modalities,including MR elastography and shearwave elastography.Additionally,we examined the role of SS using elastography in predicting the presence of esophageal varices and its potential impact on reducing the need for endoscopic screening.Studies have demonstrated that splenic elastography correlates well with PH severity,with cut-off values ranging between 45 kPa and 50 kPa for significant PH detection.Splenic elastography,when combined with platelet count and LS measurements,improves diagnostic accuracy and risk stratification for the occurrence of variceal bleeding.Despite its clinical promise,technical challenges such as patient positioning,body habitus,and probe selection remain key limitations.Notably,splenic elastography may be particularly useful in diagnosing NCPH,where LS remains normal but PH is present.Splenic transient elastography is a valuable adjunct in the non-invasive assessment of PH.Its ability to predict varices,differentiate between CPH and NCPH,and reduce unnecessary endoscopies suggests that it should be incorporated into routine hepatology practice.Future research should focus on refining SS cut-offs,evaluating its cost-effectiveness,and integrating splenic elastography into clinical guidelines for PH management.
文摘Artemisia dracunculus L.,or tarragon,is a perennial herb from the Asteraceae family that is extensively cultivated for its aromatic leaves,which are valued for its preventative and therapeutic properties in both cookery and traditional medicine.This study aims to investigate the antibacterial,antioxidant,and anti-inflammatory properties of A.dracunculus(tarragon)essential oil(ADEO),with estragole(57.23%)identified as the major compound through gas chromatography-mass spectrometry(GC-MS)analysis.ADEO exhibited varying degrees of antibacterial activity,with Escherichia coli showing higher resistance inhibition zone(IZ)=14.7±0.58 mm,minimum (inhibitory concentration(MIC)=2%and minimum bactericidal concentration(MBC)=4%),while Bacillus subtilis(IZ=24.05±2.11 mm and MIC=MBC=0.125%)and Staphylococcus aureus(IZ=18.69±1.45 mm,MIC=0.0612%and MBC=0.125%)were more sensitive to its actions.Antioxidant ability was assessed using 1,1-diphenyl-2-picrylhydrazil(DPPH),2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS),xanthine oxidase inhibition,and beta-carotene bleaching assays.ADEO showed remarkable antiradical effect on DPPH(IC_(50)=127.05±3.47μg/mL)and ABTS radical(IC_(50)=89.60±8.73μg/mL)as well as significant inhibition of xanthine oxidase(IC_(50)=47.9±2.04μg/mL)and lipid peroxidation(IC_(50)=231.63±5.21μg/mL).ADEO also showed significant anti-inflammatory activity by inhibiting the enzymesCOX-1(IC_(50)=59.2±2.43μg/mL),Cyclo-oxygenase-2(COX-2)(IC_(50)=74.68±1.34μg/mL)and 5-lipooxygense(5-LOX)(IC_(50)=93.18±1.87μg/mL),which are involved in the inflammatory pathway.These findings suggest that ADEO,with its high estragole content,holds promising potential as a natural antibacterial,antioxidant,and anti-inflammatory agent for preventive and therapeutic applications.Further research is needed to explore its safety and efficacy in clinical settings.

文摘Polyphenols,a diverse group of naturally occurring compounds found in plants,have garnered significant attention for their potential therapeutic properties in treating neurodegenerative diseases(NDs).The Wnt/β-catenin(WβC)signaling pathway,a crucial player in neurogenesis,neuronal survival,and synaptic plasticity,is involved in several cellular mechanisms related to NDs.Dysregulation of this pathway is a hallmark in the development of various NDs.This study explores multiple polyphenolic compounds,such as flavonoids,stilbenes,lignans,and phenolic acids,and their potential to protect the nervous system.It provides a comprehensive analysis of their effects on the WβC pathway,elucidating their modes of action.The study highlights the dual function of polyphenols in regulating and protecting the nervous system,providing reassurance about the research benefits.This review provides a comprehensive analysis of the results obtained from both in vitro studies and in vivo research,shedding light on how these substances influence the various components of the pathway.The focus is mainly on the molecular mechanisms that allow polyphenols to reduce oxidative stress,inflammation,and apoptotic processes,ultimately improving the function and survival of neurons.This study aims to offer a thorough understanding of the potential of polyphenols in targeting the WβC signaling pathway,which could lead to the development of innovative therapeutic options for NDs.
文摘Background: In children, acute bacterial rhinosinusitis (ABRS) is often complicated by ophthalmological and/or neurological involvement. These complications should be known and recognized, as they require urgent treatment with intravenous antibiotics and close in-hospital monitoring. In this study, we aimed to identify the main risk factors associated with the development of complications in children aged 2 - 17 years with ABRS. Methods: We conducted a retrospective cohort study of patients with ABRS complications in a primary hospital. Participants were divided into two groups: the control group comprising patients without complications (Group 1, n = 82) and the study group comprising patients with complications requiring hospitalization (Group 2, n = 41). We assessed the sociodemographic, clinical, and imaging data of both groups. Using multivariate logistic regression, we assessed risk factors of ABRS complications. Results: No socio-demographic characteristics were associated with ABRS complications (p ≥ 0.05). Factors associated with complications were delay in consultation (t = 5.282;p Conclusions: Intracranial and extracranial complications of ABRS in children have become rare in our setting. These complications can be serious and potentially fatal. Risk factors of these complications are delays in consultation, the presence of ophthalmological signs, and more than one affected sinus.

文摘Background:Existing remedial approaches for relieving neuropathic pain(NPP)are challenging and open the way for alternative therapeutic measures such as electroacupuncture(EA).The mechanism underlying the antinociceptive effects of repeated EA sessions,particularly concerning the regulation of the Adora3 receptor and its associated enzymes,has remained elusive.Methods:This study used a mouse model of spared nerve injury(SNI)to explore the cumulative analgesic effects of repeated EA at ST36(Zusanli)and its impact on Adora3 regulation in the spinal cord dorsal horn(SCDH).Forty-eight male mice underwent SNI surgery for induction of neuropathic pain and were randomly assigned to the SNI,SNI+2EA,SNI+4EA,and SNI+7EA groups.Spinal cord(L4-L6)was sampled for immunofluorescence,adenosine(ADO)detection and for molecular investigations following repeated EA treatment.Results:Following spared nerve injury(SNI),there was a significant decrease in mechanical withdrawal thresholds(PWTs)and thermal nociceptive withdrawal latency(TWL)in the ipsilateral hind paw on the third day post-surgery,while the contralateral hind paw PWTs showed no significant changes.On subsequent EA treatments,the SNI+EA groups led to a significant increase in pain thresholds(p<0.05).Repeated EA sessions in SNI mice upregulated Adenosine A3(Adora3)and cluster of differentiation-73(CD73)expression while downregulating adenosine deaminase(ADA)and enhancing neuronal instigation in the SCDH.Colocalization analysis of Neun-treated cells revealed increased Adora3 expression,particularly in the SNI+7EA group.Conclusions:In conclusion,cumulative electroacupuncture treatment reduced neuropathic pain by regulating Adora3 and CD73 expression,inhibiting ADA and most likely increasing neuronal activation in the SCDH.This study offers a promising therapeutic option for managing neuropathic pain,paving the way for further research.
文摘BACKGROUND Transplantectomy has long been considered the preferred treatment for spontaneous renal graft rupture,prioritizing patient safety over kidney salvage.In the last decade,there has been an increasing number of reports showing that,in selected scenarios,conservative management through graft repair represents a feasible option,challenging traditional approaches.CASE SUMMARY We describe the case of a 37-year-old sensitized XY patient who experienced early spontaneous graft rupture after receiving his second deceased donor kidney transplant.Following temporary hemodynamic stabilization and abdominal contrast enhanced computed tomography scan assessment,the recipient was brought back to theatre for surgical exploration.Possible causes of irreversible graft damage were immediately ruled out.The fractured upper pole of the transplanted kidney was repaired using a fibrin sealant,external compression,and a tailored polyglactin 910 mesh wrapped around the graft.The post-operative course was uneventful.After 20 months of follow up,the patient is doing very well,with excellent renal function and complete reabsorption of the mesh,as demonstrated by serial ultrasound evaluations of the graft.CONCLUSION Amid organ shortages and sensitized patients,graft nephrectomy is reserved for severe injuries;repair using sealants and mesh is effective.
