The more severe delirium is the worst the clinical outcomes of medical illness. Despite the obvious, not much has been documented on delirium severity and its associated factors among medical inpatients in low income countries including Nigeria. Objectives: This study was conducted to examine the severity of delirium among medical inpatients admitted through the Accident and Emergency unit of Jos University Teaching Hospital as well as to assess its associated Sociodemographic and Clinical characteristics. Method: This was a cross-sectional study that employed a consecutive sampling technique to select 290 eligible subjects from medical inpatients that presented to Accident and Emergency unit of Jos University Teaching Hospital. On admission, patients were assessed for delirium using Confusion Assessment Method and severity of delirium was evaluated using Delirium Rating Scale-Revised-98. Results: Of the 105 delirious medical inpatients, 48 (45.7%) had severe delirium, 41 (39.1%) developed less severe delirium while 16 (15.2) presented with no severe delirium. Sociodemographic characteristics found to be significantly associated with less to more severe delirium include male gender (P = 0.001), nonprofessionals (P = 0.003), income range of N20,000 - N49,000 (P Conclusion: This study demonstrates that delirium is often associated with higher severity in Accident and Emergency unit admission and there are strongly associated clinical characteristics to watch out for in high risk medical inpatients.展开更多

José Antonio Dam is the main receiving body of this river that is being contaminated by, industrial wastewater, of which about 70% is inorganic, as well as discharges municipal and agricultural, driving a lot of material in suspension. This dam acts as a regulator of avenues and its water is used for agricultural irrigation and its sediments are used as sludge to improve agricultural soil in the surroundings. One of the studies that have been carried out is to determine the geochemical distribution of heavy metals in the sediments of this dam, as well as its adsorptive capacity towards different metals. It has been observed that these sediments acts as metal contaminants sequester. Knowing the composition and morphology of these sediments can provide information to understand the mobility of different heavy metals it contains, and potential health risk, which can finally lead to the establishment of purification capacity of this sludge.展开更多

The paper motivated us to use state-of-the-art computational technique to investigate the risks of the tin mining activity in Jos-Plateau, Nigeria on large mammals (e.g. cattle). The Tier 2 Erica Tool assessment was used to estimate the total dose rate and risk quotients of these reference terrestrial animals. Our investigation revealed that the expected and conservative risk quotients of large mammals due to internal and external exposure to enhanced level of radioactivity are 0.05 and 0.16, respectively. Since the risk quotients are less than unity, this indicates that there is less than 5% probability that the screen dose rate (10 μGy•h–1) is exceeded. The estimated total dose rate to large mammals is 0.52 μGy•h–1 which is not statistically significant. A critical analysis of [1] is presented in the introductory part of this paper.展开更多

There was a redistribution of health care resources in order to deal with the effects of the pandemic, with a corresponding consequence on other clinical services rendered. The extent of this effect on other non COVID 19 related services has been reported in other centres worldwide. In our own setting, health care resources are limited with suboptimal access even in normal situations. <strong>Objective. </strong>We sought to evaluate the effects of the COVID 19 pandemic on elective surgical services in our hospital. <strong>Methods.</strong> This was a cross sectional comparative study carried out at the Jos University Teaching hospital, (North central, Nigeria) of the elective surgical services rendered during the first wave of the COVID 19 pandemic lockdown covering the period April to June 2020 with a corresponding period of the preceding year 2019. Data was obtained from the hospital records department, theatres and service areas for clinic attendance, elective surgeries and ward occupancy. The paired sample t-test was used to compare the assessed variables across the three months of both years with a level of significance of P < 0.05. <strong>Results.</strong> There was mean clinic attendance of 2859.33 ± 223.36 covering the three months in 2019 as against a mean attendance of 648.67 ± 578.24 covering a similar period in 2020, P = 0.037. The elective surgical procedures carried out across the surgical specialties over the period in 2019 gave a mean of 352.33 ± 44.60 as opposed to 64.001 ± 7.32 over the corresponding period in 2020, P = 0.018. Ward occupancy over April to June 2019 was a mean 297.33 ± 18.58 across the various surgical wards and 158.33 ± 25.70 in the same period in 2020, P = 0.007. <strong>Conclusion.</strong> There was a significant reduction in the elective surgical services rendered in the hospital during the first wave of the COVID 19 pandemic compared to a corresponding period in the preceding year. This decline in elective surgical services would have negatively affected the access to health care. Thus measures to clear the backlog of elective surgical procedures would be required.展开更多

Following approval, a health talk and explanation of the aims and objectives, their consent was obtained in writing. Two-staged sampling with a sociodemographic questionnaire and Hopkins Symptom Checklist-25 followed by urine drug testing was done. The participants were debriefed on the findings while maintaining strict confidentiality. There were 65 males and 141 females. <strong>Results</strong>: Lifetime prevalence rate of any substance use was 21.8%. More females 33 (23.4%) than males 12 (18.5%) used substances. Only 9 (4.5%) volunteered their substance use, the rest was revealed by the urine testing. Prevalence of alcohol was 23 (11.2%), ketamine 13 (6.3%), nicotine 3 (1.5%), benzodiazepines 3 (1.5%), cannabis 2 (1.0%) and opiods 1 (0.5%). Symptoms of psychological distress were high as 118 (57.3%) and 82 (38.8%) were symptomatic for anxiety and depression respectively.

Characterization of the dust particles shows that the concentration of fine dust ( μm) ranged from 55.0 - 124.9 μg/m3 while the coarse dust (2.5 - 10 μm) varied from 20.0 - 124.4 μg/m3. FAAS analysis of the respirable dust shows that the concentrations of heavy metals ranged from 0.121 - 0.832 mg/kg Pb, 0.019 - 0.111 mg/kg Cr, 0.171 - 1.081 mg/kg Fe, 0.002 - 0.056 mg/kg Mn, 0.002 - 0.438 mg/kg Cd, 0.696 - 1.712 mg/kg Zn, 0.025 - 0.571 mg/kg Cu, and 0.021 - 0. 478 mg/kg Ni, across the sites studied. The main sources of these heavy metals in the sampled area could be attributed to anthropogenic activities like open incineration of waste and vehicular traffic. The concentrations of Cd, Mn and Ni were found to be far above the standard limits prescribed by the WHO for respirable dust. These results convey the health risk the inhabitants in the study area are exposed to. We therefore recommend that measures be taken to regulate these anthropogenic展开更多

Women of reproductive age are mostly affected and infected with the HIV disease. Methodology: A cross-sectional study of 216 randomly selected women that booked for antenatal care at the Faith Alive Foundation and PMTCT centre Jos between 1st July to 31st December, 2014 was carried out. Information regarding age, parity, gestational age at booking, educational status and HIV sero-status of the clients was analysed. Screening test was conducted in a serial two step approval using determine and UNIGOLD as the confirmatory test, while STAT-PAK was the tie-beaker with discordant result as per the national algorithm. Positive samples were confirmed by western blot method. Result: A total of 18 women out of the 216 women studied were positive giving a sero-prevalence rate of 8.3%. The highest sero-prevalent rate was amongst 25 - 29 years age group (31.5%). Women of parity 1 - 4 constituted the highest group of 62.9%. Majority of the women 65.7% booked in the second trimester while 26.9% booked in the 3rd trimester. Most of the women 47.2% had secondary school education while only 5.6% of them had no form of education. Conclusion: HIV infection prevalence rate among antenatal attendants at Faith Alive Foundation and PMTCT centre Jos is still high. Multisectorial approach and intervention strategies should be further scaled up for the prevention of vertical transmission of the virus. However, it is worth noting that it is mainly an HIV/AIDS hospital which should have affected the outcome.展开更多
