Objective: The objective of our study was to investigate the association between placental malaria lesions and severe pre-eclampsia. Methodology: We conducted a prospective analytical cross-sectional study in two University Hospitals in the city of Yaounde (Yaounde Central Hospital and the Gynaecological Obstetrics and Paediatrics Hospital), and in the laboratory of the Centre Pasteur in Yaounde over an eight-month period (1st January 2021 – 1st September 2021). All patients with pre-eclampsia diagnosed according to the criteria of the International Society for the Study of Hypertension (ISSHP) and free of chronic metabolic or infectious pathology were included in this study. The patients were divided into two groups: group 1 (mild pre-eclampsia) and group 2: severe pre-eclampsia. Socio-demographic, clinical and histopathological characteristics specific to pre-eclampsia and placental malaria were investigated. Statistical analysis was performed with SPSS 23.0 software, Chi 2 was used to compare categorical variables, Student t-test was used to compare means, and logistic regression was used to assess the association between placental malaria lesions and PES. Results: The mean age of our study population was 29.93 ± 7.36 years versus 28.28 ± 7.18 years in patients with mild and severe pre-eclampsia respectively. Pre-eclampsia placental lesions (accelerated villous maturation, infarction) were significantly greater in patients with severe pre-eclampsia (p Conclusion: Placental malaria lesions were significantly associated with severe pre-eclampsia and increased the risk of developing severe pre-eclampsia placental lesions by a factor of 10.展开更多

The study compared the efficacy and safety profile of intravenous labetalol and hydralazine in the control hypertension in severe pre-eclampsia. Materials and Methods: One hundred patients who presented with severe pre-eclampsia were randomized into two study groups. The fifty patients in each arm of the study received either intravenous labetalol or intravenous hydralazine for the control of blood pressure. Results: The mean age of the labetalol subjects was 28.6 ± 5.47 years while that of their hydralazine counterparts was 29.12 ± 5.77 years. The majority of respondents in both groups were primigravidae (76% vs. 78%) (P = 0.813). The number of doses of drug needed to significantly lower the mean systolic blood pressure was slightly lower in the labetalol group (2 doses) compared to the hydralazine group (5 doses) (t = 0.803<sup>Y</sup>, P = 0.977). The incidence of headaches which were the commonest complaints was comparable in both groups 8% and 10% of respondents respectively (P > 0.05). Conclusion: Although both intravenous labetalol and hydralazine are useful in patients with severe pre-eclampsia, the response to labetalol was better with comparable side effects.展开更多

Aim of the Work: To identify different factors predicting transformation of non-severe pre-eclampsia in to pre-eclampsia with severe features. Patients and Methods: This prospective cohort study was conducted at tertiary care hospital at Ain Shams University hospitals from June 2021 till January 2022 and performed on total of 100 patients who diagnosed as non-severe pre-eclampsia after exclusion of severity features. Results: The current study revealed that transformation to severe pre-eclampsia occurred in 33% of the studied cases. Body mass index (BMI), past and family histories of preeclampsia statistically were significantly higher in cases transformed into preeclampsia with severe features. Admission blood pressure, albumin dipstick, Oligohydramnios and IUGR statistically were significantly higher in cases with transformation from non-severe pre-eclampsia into pre-eclampsia with severe features. Platelet count statistically was significantly lower in cases with transformation from non-severe pre-eclampsia into pre-eclampsia with severe features Conclusion: Our study results identified the most important clinical risk factors for transformation to severe features of pre-eclampsia from non-severe features and provided new information on the level of risk associated with specific combinations of risk factors (BMI ≥ 35.4, admission systolic blood pressure, admission diastolic blood pressure, albumin dipstick 4+ and platelets count) with low significant diagnostic performance in predicting transformation from non-severe pre-eclampsia into pre-eclampsia with severe features.展开更多

Objective: To determine if administering loading dose of MgSo4 on pregnant women with severe preeclampsia and eclampsia at primary care level would improve maternal and fetal outcomes. Method: Two sets of Primary Health Care (PHC) facilities were identified;one served as experimental one and the other as control. The community health extension workers (CHEWs) and the community health officers (CHOs) at the experimental PHCs were trained to administer the loading dose of MgSo4 for patients with SPE/E, in addition to other supportive treatments, before making a referral while the control PHCs did not give MgSo4, and neither administered diazepam as an alternative or no anti-convulsant at all, before making a referral to higher centers. Patients from the experimental and control facilities were prospectively monitored for fetal and maternal outcomes, namely maternal and fetal deaths, and for toxic effects of MgSo4 in the experimental arm. Results: Of the 150 patients recruited, 82 (55%) were in the experimental group and 68 (45%) were in the control group. 90% of the patients in the experimental group defaulted after receiving the loading dose of MgSo4 while the remaining 10% completed the referral process. 44% of those in the control group completed the referral process. There were 3 maternal and 3 perinatal deaths, all in the control group. No adverse outcome (maternal or fetal death) or toxic effect was recorded among the recipients of MgSo4. Conclusion: This study suggests that lower-cadre health care professionals at PHCs can administer the loading dose of MgSo4 to SPE/E patients to improve maternal and fetal survival in critical states, without significant risk of adverse effects. However, the lack of compliance with referral processes remains a huge challenge.展开更多

In low-income countries, renal dysfunction (RD) contributes to about 34% mortality in under-five children with severe acute malnutrition. This study aimed to determine the impacts of severe acute malnutrition on the kidney among the admitted under-five children. Methods: In this prospective longitudinal observational study, a total of 190 children aged 6 to 59 months were enrolled from Iringa and Dodoma tertiary hospitals. Socio-demographic, clinical and laboratory data were collected using a structured questionnaire. Estimated Glomerular Filtration Rate (eGFR) and urine albumin creatinine ratio (uACR) were used to determine RD. Data analysis was done using SPSS version 26 and statistical significance was assumed for factors with p-value Results: Out of 190 children with severe acute malnutrition, 36 (19%) had renal dysfunction. Factors associated with RD in malnourished children were the history of local herbs used within one week (AOR = 5.85, 95% CI [1.41, 24.319], p = 0.0152), Acute watery diarrhea with severe dehydration (AOR = 2.15, 95% CI [1.033, 4.711], p = 0.0166), and positive urine leukocytes (AOR = 19.91, 95% CI [4.09, 96.989], p = 0.0002). At three months of follow up, out of 36 children with RD, 20 (55.56%) attained full recovery, while 4 (11.11%) developed chronic kidney disease (CKD). Children with RD had prolonged hospital stays for more than 14 days with a mean 12.25 ± 5.00 days compared to those with no RD with a mean 6.29 ± 1.68 days (p Conclusion: Renal dysfunction is common among children with severe acute malnutrition. It is associated with prolonged hospital stays and increased mortality. Further studies which can determine the burden of RD in children with severe acute malnutrition as compared to those with no severe acute malnutrition are needed.展开更多

We analyzed nowcasting techniques by integrating a high-resolution numerical weather prediction model with these convective parameters. Based on the CMA-GD 1-km model and its assimilation system, we conducted repeated tests on radar reflectivity data assimilation and analyzed their impact on nowcasting accuracy. Based on these analyses, we proposed a method to improve model forecasts using the useful indicative information provided by high-frequency radar reflectivity data and convective parameters. The improved method was applied to the CMA-GD 1-km model for nowcasting tests. Evaluations from batch tests and case analysis show that the proposed method significantly reduced the model's false alarm rates and improved its nowcasting performance.展开更多

The community health extension workers (CHEWs) and the community health officers (CHOs) at the experimental PHCs were trained to administer the loading dose of MgSo4 for patients with SPE/E, in addition to other supportive treatments, before making a referral while the control PHCs did not give MgSo4, and neither administered diazepam as an alternative or no anti-convulsant at all, before making a referral to higher centers. Patients from the experimental and control facilities were prospectively monitored for fetal and maternal outcomes, namely maternal and fetal deaths, and for toxic effects of MgSo4 in the experimental arm. Results: Of the 150 patients recruited, 82 (55%) were in the experimental group and 68 (45%) were in the control group. 90% of the patients in the experimental group defaulted after receiving the loading dose of MgSo4 while the remaining 10% completed the referral process. 44% of those in the control group completed the referral process. There were 3 maternal and 3 perinatal deaths, all in the control group. No adverse outcome (maternal or fetal death) or toxic effect was recorded among the recipients of MgSo4. Conclusion: This study suggests that lower-cadre health care professionals at PHCs can administer the loading dose of MgSo4 to SPE/E patients to improve maternal and fetal survival in critical states, without significant risk of adverse effects. However, the lack of compliance with referral processes remains a huge challenge.

文摘Background:Humanized mouse models are essential for studying the human immune response and antibody development.However,conventional models show limited B cell maturation and antigen-specific humoral responses.To overcome these limitations,we used the NOG-EXL mice expressing human interleukin 3(IL-3)and granulocyte-macrophage colony-stimulating factor(GM-CSF)to enhance myeloid and B-cell lineage differentiation.Methods:Human CD34^(+)hematopoietic stem cells(HSC)were transplanted into NOG-EXL mice to produce humanized immune systems.After immune cell reconstitution was confirmed across 12 weeks,the mice were immunized twice with inactivated severe fever with thrombocytopenia syndrome virus(SFTSV)antigens.Peripheral blood mononuclear cells and splenocytes were analyzed using multicolor flow cytometry to assess human immune cell subsets.Antigen-specific immunoglobulin G(IgG)production was quantified using enzyme-linked immunosorbent assay(ELISA),and virus-specific B cells were isolated using antigen-labeled recombinant protein probes.Results:Twelve weeks after transplantation of HSCs into NOG-EXL mice,they exhibited robust engraftment of human leukocytes,including T,B,and dendritic cells,compared to NOG mice.Unlike NOG mice,humanized NOG-EXL mice exhibited an increase in human IgG levels,indicating the production of human antibody responses to antigens.Humanized NOG-EXL mice were immunized twice every 2 weeks with inactivated SFTSV,and antigen-specific human antibodies against the virus were detected in the mouse sera by ELISA.Sera from SFTSV-immunized humanized mice demonstrated neutralizing activity against SFTSV,confirming the induction of functional virus-specific neutralizing antibodies.Antigen-binding IgG-positive human B cells were isolated from mouse splenocytes using recombinant protein probes.Conclusion:This model provides a valuable platform for evaluating humoral immunity and isolating B cells using high-affinity human monoclonal antibodies without genetic engineering.
文摘Severe acute pancreatitis(SAP)can induce acute respiratory distress syndrome(ARDS)and abdominal compartment syndrome(ACS).Although prone position ventilation(PPV)can improve outcomes in patients with ARDS,there is significant controversy regarding its concurrent use with ACS owing to concerns of increased risk of intra-abdominal pressure(IAP).[1]We present a case of successful PPV application without adverse eff ects.

文摘Severe fever with thrombocytopenia syndrome(SFTS)is a novel emerging acute infectious disease caused by severe fever with thrombocytopenia syndrome virus(SFTSV),characterized by high fever and thrombocytopenia.It has been proved that traditional Chinese medicine(TCM)has displayed definite therapeutic effects on viral hemorrhagic fever,indicating its potential to treat SFTS.In this study,SFTS-relative key targets were predicted via gene ontology(GO)analysis and kyoto encyclopedia of genes and genomes(KEGG)enrichment analysis.Molecular docking was then used to select stable binders.Molecules matched TCMs were identified,and a new prescription,Qingqi Guxue decoction(QQGX),was formulated to clear heat and nourish blood,with a resulting drug composition network.We explored the optimal drug proportion for QQGX.Through an in-depth study of molecular mechanisms,we found that QQGX induces S phase arrest by promoting the degradation of cyclin A2(CCNA2)and cyclin-dependent kinase 2(CDK2),thereby inhibiting SFTSV replication.Finally,we verified the effectiveness and safety of QQGX based on the mouse liver bile duct organoid model infected with SFTSV.In summary,our study prepared a TCM decoction using the method of network pharmacology.This decoction has a significant inhibitory effect on the replication of SFTSV and provides a new treatment strategy for hemorrhagic fever with TCM.
文摘Background: Severe acute malnutrition (SAM) is one of the major public health problems associated with increased mortality in under-five children. In low-income countries, renal dysfunction (RD) contributes to about 34% mortality in under-five children with severe acute malnutrition. This study aimed to determine the impacts of severe acute malnutrition on the kidney among the admitted under-five children. Methods: In this prospective longitudinal observational study, a total of 190 children aged 6 to 59 months were enrolled from Iringa and Dodoma tertiary hospitals. Socio-demographic, clinical and laboratory data were collected using a structured questionnaire. Estimated Glomerular Filtration Rate (eGFR) and urine albumin creatinine ratio (uACR) were used to determine RD. Data analysis was done using SPSS version 26 and statistical significance was assumed for factors with p-value Results: Out of 190 children with severe acute malnutrition, 36 (19%) had renal dysfunction. Factors associated with RD in malnourished children were the history of local herbs used within one week (AOR = 5.85, 95% CI [1.41, 24.319], p = 0.0152), Acute watery diarrhea with severe dehydration (AOR = 2.15, 95% CI [1.033, 4.711], p = 0.0166), and positive urine leukocytes (AOR = 19.91, 95% CI [4.09, 96.989], p = 0.0002). At three months of follow up, out of 36 children with RD, 20 (55.56%) attained full recovery, while 4 (11.11%) developed chronic kidney disease (CKD). Children with RD had prolonged hospital stays for more than 14 days with a mean 12.25 ± 5.00 days compared to those with no RD with a mean 6.29 ± 1.68 days (p Conclusion: Renal dysfunction is common among children with severe acute malnutrition. It is associated with prolonged hospital stays and increased mortality. Further studies which can determine the burden of RD in children with severe acute malnutrition as compared to those with no severe acute malnutrition are needed.

文摘Taking short-duration heavy rainfall and convective wind gusts as examples, the present study examined the characteristics of radar reflectivity and several convective parameters. We analyzed nowcasting techniques by integrating a high-resolution numerical weather prediction model with these convective parameters. Based on the CMA-GD 1-km model and its assimilation system, we conducted repeated tests on radar reflectivity data assimilation and analyzed their impact on nowcasting accuracy. Based on these analyses, we proposed a method to improve model forecasts using the useful indicative information provided by high-frequency radar reflectivity data and convective parameters. The improved method was applied to the CMA-GD 1-km model for nowcasting tests. Evaluations from batch tests and case analysis show that the proposed method significantly reduced the model's false alarm rates and improved its nowcasting performance.
文摘Objective:To explore the clinical effects of applying responsibility-based holistic nursing in elderly patients with severe pneumonia.Methods:Ninety-six elderly patients with severe pneumonia admitted to a hospital from January 2023 to December 2024 were selected and divided into an observation group(52 cases)and a control group(44 cases)based on a random number table method.The observation group received responsibility-based holistic nursing,while the control group received basic nursing.The clinical effects(time to normalize body temperature,disappearance of cough,disappearance of dyspnea symptoms,disappearance of lung rales,changes in oxygenation index)and nursing satisfaction were observed in both groups.Results:The observation group showed superior results compared to the control group in terms of time to normalize body temperature,disappearance of cough,disappearance of dyspnea symptoms,disappearance of lung rales,and changes in oxygenation index,with statistically significant differences(P<0.05).The satisfaction rate with nursing services in the observation group(92.31%)was significantly higher than that in the control group(86.36%)(P<0.05).Conclusion:Implementing responsibility-based holistic nursing in elderly patients with severe pneumonia can improve their oxygenation function,enhance quality of life,and increase nursing satisfaction.
