Exploring COVID-19 census burdens by US hospital characteristics: Implications of quality reporting at rural and critical access hospitals.

PURPOSE: By assessing longitudinal associations between COVID-19 census burdens and hospital characteristics, such as bed size and critical access status, we can explore whether pandemic-era hospital quality benchmarking requires risk-adjustment or stratification for hospital-level characteristics. METHODS: We used hospital-level data from the US Department of Health and Human Services including weekly total hospital and COVID-19 censuses from August 2020 to August 2023 and the 2021 American Hospital Association survey. We calculated weekly percentages of total adult hospital beds containing COVID-19 patients. We then calculated the number of weeks each hospital spent at Extreme (≥20% of beds occupied by COVID-19 patients), High (10%-19%), Moderate (5%-9%), and Low (<5%) COVID-19 stress. We assessed longitudinal hospital-level COVID-19 stress, stratified by 15 hospital characteristics including joint commission accreditation, bed size, teaching status, critical access hospital status, and core-based statistical area (CBSA) rurality. FINDINGS: Among n = 2582 US hospitals, the median(IQR) weekly percentage of hospital capacity occupied by COVID-19 patients was 6.7%(3.6%-13.0%). 80,268/213,383 (38%) hospital-weeks experienced Low COVID-19 census stress, 28% Moderate stress, 22% High stress, and 12% Extreme stress. COVID-19 census burdens were similar across most hospital characteristics, but were significantly greater for critical access hospitals. CONCLUSIONS: US hospitals experienced similar COVID-19 census burdens across multiple institutional characteristics. Evidence-based inclusion of pandemic-era outcomes in hospital quality reporting may not require significant hospital-level risk-adjustment or stratification, with the exception of rural or critical access hospitals, which experienced differentially greater COVID-19 census burdens and may merit hospital-level risk-adjustment considerations.

Audit of Tracheostomy Care Practices in a Nigerian Tertiary Neurosurgical Intensive Care Unit According to Published Guidelines.

INTRODUCTION: Chest infections are a frequently encountered problem in patients admitted to the intensive care unit (ICU), more so in tracheostomised patients. This study aimed to audit the tracheostomy care practices in patients with neurosurgical pathologies in the ICU of Wellington Clinics Abuja, a tertiary neurosurgical hospital in Nigeria. METHODS: We conducted a closed-loop audit with mixed methods involving analysis of 24 patients who had tracheostomy within the first two weeks of neurosurgical pathology at a tertiary neurosurgical hospital and semi-structured interviews to determine tracheostomy care practices among the primary caregivers - nurses, intensivists, and doctors. RESULTS: Of the 161 ICU admissions in the first cycle, 22 patients received tracheostomy, 16 met the eligibility criteria. At re-audit (second cycle), eight of 40 patients met the criteria. All the patients received open suctioning through a dual cannula-cuffed tracheostomy tube and had independent portable suction units. In the baseline audit (first cycle), suction catheters were reused for 12-24 hours in each patient and were stored in varying combinations of normal saline and Savlon antiseptic (5 mg of cetrimide (0.5% w/w) and 1 mg of chlorhexidine digluconate (0.1% w/w)). The frequency, technique, and assessment of the need for airway suctioning were inconsistent among caregivers interviewed. All 16 patients had at least one episode of pneumonia, 10 patients had a second episode, and two patients had > two episodes. One mortality was recorded directly attributable to the complications of pneumonia. While in the re-audit, with adherence to recommendations, three patients suffered one episode of pneumonia and only one had a second episode. No mortality was recorded. CONCLUSION: A standard practice guideline was necessary for tracheostomy care in our ICU. In low-resource settings, stated recommendations such as single-use suction catheters and improved hygienic practices can reduce rates of pneumonia in tracheostomised patients.

Antimicrobial use among paediatric inpatients in a Nigerian tertiary hospital: A three-year point prevalence survey.

Aim: Antimicrobials are among the most widely prescribed therapeutic agents among paediatric population. Irrational use of these agents increases the risk of antimicrobial resistance. We described the prevalence and pattern of antimicrobial use among paediatric inpatients from 2017 to 2019. Subject and Method: The study was a repeated point prevalence survey over a 3-year period using the global point prevalence standardized tools among all paediatric inpatients. The prevalence of antimicrobial use, the prescription indicators and patterns of antimicrobial use were estimated. Result: Among 191 paediatric inpatients assessed, the 3-year period prevalence antimicrobial use was 85.9% (164/191) with prevalence of 80.6% in 2017, 94.6% in 2018, and 83.6% in 2019. Antimicrobial agents used ranged from one agent (20.1%) to five different agents (5.5%). Parenteral route (66.6%) was the preferred route of administration. The reason for the use of antimicrobial agents (92.6%) and the stop/review date (99.5%) were mostly well documented. Only 4.5% of the antimicrobial use were targeted. There were no antimicrobial guidelines or policy guiding the use of antimicrobial agents, except the national guideline on the treatment of malaria and tuberculosis. Ceftriaxone, a third generation cephalosporin was the most commonly used agent across the period under review. Community-acquired infection was the commonest indication for antimicrobial use. Conclusion: Our findings of high antimicrobial prevalence has raised the attention for the need to develop hospital-based antimicrobial guideline and antimicrobial stewardship program to protect the vulnerable children, their contacts and the environment from the impact of antimicrobial resistance.

Predicting Risky Decision Making (Odds Selection) in Regular Soccer Gamblers from Nigeria using Cognitive Tasks Combined with Non-Cognitive Measures.

As real time soccer gambling is becoming a game of choice for many Nigerian youths, there is need to examine some predictive factors that could account for risky decision making in the population. We combined some cognitive tasks (memory, concentration, executive function and problem solving) and non-cognitive measures (time taken to complete a bet, years of gambling and addiction tendency measures) to derive a more parsimonious model of predicting risky decision making in this population. Twenty-eight undergraduate students that endorsed regular involvement (at least once a week) in soccer betting and were willing to come to the psychology lab for testing were recruited. Four neuropsychological measures (Craft Story 21: Immediate and delayed, Number Span Test: Forward and backward, Trail Making Test: A&B, Tower of Hannoi and a gambling questionnaire (Gamblers Anonymous Questionnaire) were used for the study. Study design was correlational and linear regression (step wise method) was used for data analysis. Step wise regression statistics yielded nine possible model combinations with high predictive strengths. Overall, model 9 (with adjusted R2 = 0.57) that has 6 measures including one from non-cognitive and 5 from cognitive measures was adjudged to be most parsimonious putting into consideration its predictive strength and number of tasks required. The tasks in our most parsimonious model were: time taken to complete a bet (non-cognitive), Craft Story 21: immediate (cognitive: memory), Number Span Forward: Total correct and longest correct (cognitive: concentration), Trail Making Test: B (cognitive: executive function) and Tower of Hannoi: Time taken to complete (cognitive: problem solving). Pearson product moment correlation between the predictor variables and the dependent variable (number of odds selected) showed inverse correlation of Craft Story Immediate, Number Span total correct and Number span longest correct suggesting strong divergence of these variables to odd selection. Time taken to complete bet, Trail Making Test: B and time taken to complete Tower of Hannoi respectively had positive correlations with number of odds selected. Our results suggest that multiple domains of cognitive abilities and time taken to complete a bet are important for predicting gamblers at risk for poor decision making. It further suggests that use of single task for a particular cognitive domain could be sufficient in predicting persons at risk for decision making. Overall, our study suggests that risky decision making in real time sports betting could be predicted using fewer neuropsychological tasks measuring wider domains of brain behaviour and a non-cognitive measure.

Percutaneous construction of ventriculo-atrial (VA) shunt - Case report.

INTRODUCTION AND IMPORTANCE: The commonest method of elective CSF diversion remains ventriculo-peritoneal shunt (VP shunt). But in some circumstances, VP shunts fail repeatedly or becomes unattractive to the neurosurgeon and this calls for exploration of alternatives. For the index case, Ventriculo-atrial (VA) shunt was favoured and the objective in this report is to share experience gathered there from. Learning points serve to highlight the use of VA shunts as a resort in the drainage of cerebrospinal fluid in the case of repeated failures of peritoneal diversion of CSF and to explain our explain our experience with this index case. CASE PRESENTATION: A 54 years old obese woman with previous history of total abdominal hysterectomy was reported. She underwent repeated (three times) revisions of failed peritoneal end of her VP shunt on a background of obstructive hydrocephalus secondary to a posterior fossa tumour (previously excised). Following repeated failure of peritoneal catheter function, she underwent VA shunt and did well. CLINICAL DISCUSSION: The decision to place a VA shunt was made after careful deliberations. We discuss the peculiarities in placing a VA shunt. Following placement of a VA shunt, improvement was noted in her clinical condition at one week post op and has been sustained at multiple follow up clinic visits. CONCLUSION: VA shunts become an option for cerebrospinal fluid drainage when it becomes unequivocally clear in a multidisciplinary setting that the peritoneal catheter is unlikely to work in view of the unfavourable circumstances of the peritoneal cavity.

Ionizing radiation protection and the linear No-threshold controversy: Extent of support or counter to the prevailing paradigm.

This study has developed a relationship that categorized radiation protection and allows for a proper, clear, and concise review of the different classifications in terms of principles of protection, dose criteria, categories, fundamental tools, exposure situations, applications and control measures. With the groundwork laid, advances of the linear no-threshold (LNT) model which has attracted attention in the field of radiobiology and epidemiology were examined in detail. Various plausible dose-response relationship scenarios were x-rayed under low-dose extrapolation. Intensive review of factors opposing the LNT model involving radiophobia (including misdiagnosis, alternative surgery/imaging, suppression of ionizing radiation (IR) research); radiobiology (including DNA damage repair, apoptosis/necrosis, senescence protection) and cost issues (including-high operating cost of LNT, incorrect prioritization, exaggeration of LNT impact, risk-to-benefit analysis) were performed. On the other hand, factors supporting the use of LNT were equally examined, they include regulatory bodies' endorsement, insufficient statistical significance, partial DNA repair, variability of irradiated bodies, different latency periods for cancer, dynamic nature of threshold and conflicting interests. After considering the gaps in the scientific investigations that either support or counter the scientific paradigm on the use of LNT model, further research and advocacy is recommended that will ultimately lead to the acceptance of an alternative paradigm by the international regulators.

Demand for malaria rapid diagnostic test, health care-seeking behaviour, and drug use among rural community members with fever or malaria-like illness in Ebonyi state, Nigeria: a cross-sectional household survey.

BACKGROUND: A good understanding of the demand for malaria rapid diagnostic test (MRDT), malaria health care-seeking behavior, and drug use among community members is crucial to malaria control efforts. The aim of this study was to assess the demand (use and/or request) for MRDT, health care-seeking behavior, and drug use, as well as associated factors, among rural community members (both children and adults) with fever or malaria-like illness in Ebonyi state, Nigeria. METHODS: A cross-sectional household survey was conducted between October 1st and November 7th, 2018, in 18 rural geographical clusters. Data was collected using a structured interviewer-administered questionnaire. Descriptive analysis was done using summary statistics. Associated factors (socio-demographic, knowledge and opinion level) were assessed using bivariate and multivariate binomial logistic regressions while the overall effects of these factors were assessed using the "postestimation test" command in Stata. RESULTS: A total of 1310 children under 5 years of age and 2329 children ages 5 years and above and adults (excluding pregnant women) (3639 overall) participated in the study. Among the 1310 children under 5 years of age: 521 (39.8%) received MRDT of which the caregivers of 82 (15.7%) requested for the MRDT; 931 (71.1%) sought care with public/private sector providers (excluding traditional practitioners/drug hawkers) the same/next day; 495 (37.8%) sought care at government primary health centres, 744 (56.8%) sought care with the patent medicine vendors (PMVs); 136 (10.4%) sought care with traditional practitioners; 1020 (77.9%) took ACTs (=88.2%, 1020/1156 of those who took anti-malarial drugs). Generally, lower values were respectively recorded among the 2329 children ages 5 years and above and adults (excluding pregnant women). The most important overarching predictor of the demand for MRDT and care-seeking behaviour was the knowledge and opinion level of respondent female heads of households about malaria and malaria diagnosis. CONCLUSIONS: Among the rural community members with fever or malaria-like illness in Ebonyi state, Nigeria, while majority did not receive MRDT or diagnostic testing, and sought care with the PMVs, most took anti-malaria drugs, and mostly ACTs. Interventions are needed to improve the knowledge and opinion of the female heads of households about malaria and malaria diagnosis.

Social group and health-care provider interventions to increase the demand for malaria rapid diagnostic tests among community members in Ebonyi state, Nigeria: a cluster-randomised controlled trial.

BACKGROUND: The rate of diagnostic testing for malaria is still very low in Nigeria despite the scale-up of malaria rapid diagnostic test (MRDT) availability, following WHO's recommendation of universal diagnostic testing in 2010. We investigated whether a social group sensitisation and education intervention (social group intervention) and a social group intervention plus health-care provider training intervention would increase the demand (use or request, or both) for MRDTs among community members in Ebonyi state, Nigeria. METHODS: We did a three-arm, parallel, open-label, stratified cluster-randomised controlled trial in Ebonyi state, Nigeria, to evaluate the effects of two interventions compared with a control. We randomly assigned geographical clusters that were accessible (close to a road that was drivable even during the rainy seasons) and had at least one eligible public primary health facility and patent medicine vendor (those that offered MRDT services) in a 1:1:1 allocation to the control arm (receiving no intervention), social group arm (receiving sensitisation and education about MRDT), or social group plus provider arm (receiving the social group intervention plus provider training in health communication about MRDT). Investigators, participants (social groups, providers, respondents), and interviewers could not be masked to group assignments. The primary outcome was the proportion of children younger than 5 years with fever or malaria-like illness, in the 2 weeks preceding a household survey, who received an MRDT, and the coprimary outcome was the same outcome but among children aged 5 years and older (ie, up to and including 17 years) and adults (excluding pregnant women). The outcomes were measured at an individual level via household surveys before the interventions and 3 months after the end of the interventions. All analyses were done using a cluster-level method on an intention-to-treat basis. This trial is registered with ISRCTN, number ISRCTN14046444. FINDINGS: We carried out eligibility screening and recruitment of participants (clusters, social groups, and providers) between July 2 and Sept 27, 2018. 34 clusters met the eligibility criteria and 18 were randomly selected to participate and randomly assigned to arms (six clusters per arm). A mean proportion of 40·6% (SD 14·5) of eligible children younger than 5 years in the control arm received an MRDT, versus 66·7% (11·7) in the social group arm (adjusted risk difference [aRD] 28·8%, 95% CI 21·9-35·7, p<0·0001) and 71·7% (19·8) in the social group plus provider arm (aRD 32·7%, 24·9-40·5, p<0·0001), with no significant difference between the social group arm and the social group plus provider arm. A mean proportion of 36·3% (18·5) of eligible children aged 5 years and older in the control arm received an MRDT, versus 60·7% (14·0) in the social group arm (aRD 25·6%, 16·8-34·4, p=0·0004), and 59·5% (18·3) in the social group plus provider arm (aRD 28·0%, 19·5-36·5, p=0·0002), with no significant difference between the social group arm and the social group plus provider arm. INTERPRETATION: The sensitisation and education of social groups about MRDTs can significantly increase the demand for MRDTs. This intervention is pragmatic and could be applied within malaria control or elimination programmes, in Nigeria and in other high-burden countries, to enhance diagnostic testing for patients suspected of having malaria. FUNDING: There was no funding source for this study.

The Outcomes of Traumatic Acute Subdural Hematoma in a Tertiary Center in Abuja, Nigeria.

Background Acute traumatic subdural hematoma is life-threatening and is associated with high unfavorable outcomes in developing countries. Objective We aim to identify factors contributing to outcomes after severe traumatic brain injury (TBI) due to acute subdural hematoma (SDH) in patients admitted to National Hospital Abuja, Nigeria. Methods This was a retrospective review of 34 patients who consecutively underwent neurosurgery for acute SDH over five years (from January 2015 to December 2019). Demographic data, clinical characteristics, and the time intervals from injury to surgery were investigated to determine the interactions between all these factors and outcome. Outcome was graded according to the Glasgow outcome scale at the three-month follow-up. Results Out of 34 patients who had surgical evacuation for traumatic acute subdural hematoma, 15 patients died (44.1%). A significant correlation was identified between outcome and the Glasgow coma scale score at admission. No significant correlation was seen between the outcome and the age, gender and the time from injury to surgery (chi2 test, p>0.05). Conclusion The rate of unfavorable outcomes in acute subdural hematoma is high. The Glasgow coma score at admission is an important predictor for outcome in traumatic acute subdural hematoma.

Social group and health care provider interventions to increase the demand for malaria rapid diagnostic test among community members in Ebonyi state, Nigeria: study protocol for a cluster randomized controlled trial.

BACKGROUND: The World Health Organization recommended (in 2010) universal testing for suspected malaria, due to some fundamental changes in malaria trends such as the declining incidence of malaria in high-burden countries, the emergence of parasite resistance to anti-malarial drugs especially artemisinin-based combination therapies (ACTs) and the increased availability of diagnostic testing such as the malaria rapid diagnostic test (MRDT). The Nigerian government has long adopted this recommendation and with the support of foreign partners has scaled up the availability of MRDT. However, the malaria/MRDT rate in the communities is still far short of the recommendation. This study aims to evaluate the effectiveness of social group and social group/provider interventions in increasing the demand (use and/or request) for MRDT among community members with fever or malaria-like illness in Ebonyi state, Nigeria. METHODS: A three-arm, parallel, stratified cluster randomized design will be used to evaluate the effect of two interventions compared to control: control involves the usual practice of provision of MRDT services by public primary healthcare providers and patent medicine vendors; social group intervention involves the sensitization/education of social groups about MRDT; social group/provider intervention involves social group treatment plus the training of healthcare providers in health communication about MRDT with clients. The primary outcome is the proportion of children under 5 years of age with fever/malaria-like illness, in the 2 weeks preceding a household survey, who received MRDT. The co-primary outcome is the proportion of children ages 5 years and above and adults (excluding pregnant women) with fever/malaria-like illness, in the 2 weeks preceding a household survey, who received MRDT. The primary outcome will be assessed through household surveys at baseline and at the end of the study. DISCUSSION: The pragmatic and behavioural nature of the interventions delivered to groups of individuals and the need to minimize contamination informed the use of a cluster-randomized design in this study in investigating whether the social group and social group/provider interventions will increase the demand for MRDT among community members. "Pragmatic" means the interventions would occur in natural settings or real- life situations. TRIAL REGISTRATION: ISRCTN, ISRCTN14046444 . Registered on 14 August 2018.

Knowledge of antibiotic use and resistance among students of a medical school in Nigeria.

Background: Antimicrobial resistance presents a growing concern worldwide. Medical students are potential antimicrobial prescribers and stewards following graduation as doctors. The aim of this study was to assess the knowledge regarding antibiotic use and resistance among pre-final year and final year medical school students of Ebonyi State University, Nigeria. Methods: A cross-sectional study was conducted among all the 184 pre-final and final year medical students of the College of Medicine at Ebonyi State University, Nigeria. Information was collected in April 2018 using a semi-structured, self-administered questionnaire and data were analysed with Epi-Info Version 7.2. Analytical decisions were considered significant at P < 0.05. Results: Respondents were mostly males (62.5%), aged 20-29 years (68.9%) with 60.9% of them in the final year class. Eighty-seven percent of them desired more education on antibiotic use and resistance. Majority 119 (64.7%) respondents had good knowledge of antibiotic use and resistance, however, 39% incorrectly answered that bacteria cause common cold. Only 103 (56.0%) of them had positive practice of antibiotic use. While 8.2% of respondents always consulted a doctor before starting an antibiotic. 37.2% of them never discarded their remaining leftover medications. Knowledge was associated with respondent's gender (P=0.035) while practice was associated with the class of study (P<0.001). Conclusion: There was good knowledge of antibiotic use and resistance, however, practice levels were poor. There is need to enrich existing courses and training about antibiotic use in the curriculum of the medical schools with more emphasis on antimicrobial stewardship.

Effect of multiple intervention models on uptake of HIV testing services and sexual behaviour among residents of military cantonments in south-east Nigeria.

Background: HIV testing and counselling (HTC) has been a viable tool in controlling the spread of HIV/AIDS, and serves as the entry point in the HIV care and treatment cascade. In Africa, HIV-related morbidity and mortality are high with thousands still unaware of their HIV status. This study assessed the effect of on-site multiple HIV control interventions on the uptake of HTC services, knowledge and sexual behaviour among residents of two military cantonments [barracks] in south-east Nigeria. Methods: A quasi-experimental study was conducted among residents of cantonments in two states in Nigeria. A multistage sampling technique was used to select 350 respondents each at intervention and control sites. A pre-tested interviewer-administered questionnaire was used to collect information. On-site HTC services were established, with the training of HTC counsellors and peer educators. HIV awareness carnivals, with information, education and communication activities were conducted. Data were analysed with SPSS software and statistical tests carried out at 5% level of significance. Results: There was a statistically significant increase in the uptake of HTC services from 41.1% pre-intervention to 81.1% post-intervention (χ2 = 113.8, p < 0.001). Also, knowledge about HIV improved significantly from 35.4% to 98.8% (p < 0.001) in the intervention group, together with avoidance of risky sexual behaviour. Conclusion: The study demonstrated the effectiveness of multiple on-site intervention models in improving HIV knowledge, uptake of HTC services, and sexual behaviour among diverse cantonment residents. Establishing on-site HTC services and a constellation of awareness events will contribute significantly towards HIV prevention and control among high-risk populations.

Synthesis, Purification and Characterization of Polymerizable Multifunctional Quaternary Ammonium Compounds.

Methacrylate analogs of quaternary ammonium salts functionalized with carboxylic (AMadh1 68.8% yield, AMadh2 53.2% yield) and methoxysilane (AMsil1 94.8% yield, AMsil2 36.0% yield) groups were synthesized via Menschutkin reaction. Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectroscopy (1H, 13C and 2D 1H-13C heteronuclear single quantum coherence (HSQC) NMR), mass spectrometry, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) were utilized to validate structures and characterize thermal properties of the novel multifunctional quaternary ammonium salts synthesized. The potential adhesive, coupling and antimicrobial properties of these multifunctional monomers encourage their further comprehensive evaluation in conventional and experimental copolymers and composites.

Hydrodynamic cavitation for the rapid separation and electrochemical detection of Cryptosporidium parvum and Escherichia coli O157:H7 in ground beef.

Foodborne illnesses are a major contributor to misery and health challenges in both rich and poor nations. Illnesses from pathogens such as Escherichia coli and Cryptosporidium parvum oocysts account for most of the cases of diarrhea in the world. Many standard methods exist for detecting these pathogens in water. However, these standard methods do not readily translate to the detection of the same pathogens in food. Detection techniques for pathogens in food are often inadequate, due to their inability to completely separate pathogens from food matrices. In this paper, we present a technique to separate and detect both Escherichia coli cells and Cryptosporidium parvum oocysts that have been embedded in ground meat. We achieve this objective by combining enzymatic digestion of the meat, hydrodynamic cavitation to disassemble pathogens from the meat, immunomagnetic separation to purify meat samples and indirect electrochemical detection of the target pathogens. Our use of hydrodynamic cavitation to separate pathogens is compared against an industry standard separation technique. Results indicate that the use of hydrodynamic cavitation amplifies the detection capabilities of our sensing technique and is overall comparable to or better than conventional stomacher sample preparation.

Inequitable coverage of vitamin A supplementation in Nigeria and implications for childhood blindness.

BACKGROUND: Vitamin A deficiency (VAD) is of major public health significance; it is a risk factor for childhood deaths from diarrhoea and measles in low and middle-income countries and an important cause of preventable childhood blindness in low income countries. Vitamin A supplementation (VAS) is being implemented in many LMICs and high coverage reduces the prevalence of blinding corneal diseases in children. However, national estimates of coverage may not reveal any inequities in intra country coverage. The aim of this study is to assess factors influencing VAS coverage and also assess the relationship between VAS coverage and childhood corneal blindness in Nigeria. METHODS: Data were collected from the Nigeria Demographic and Health Survey (NDHS) 2013 and the published literature on population-based childhood blindness surveys in Nigeria. The main outcome measure was the proportion of eligible children who received VAS in the last 6 months preceding the survey. Study factors comprised a range of socioeconomic, and individual factors. Data were analysed using STATA V.12.1 (Statcorp, Texas). To explore the effects of the independent variables on VAS coverage, bivariate and multivariate regression was done. Variables with p < 0.05 in the final multivariable model were considered as independent factors. For the population-based childhood blindness surveys, aggregated and disaggregated data were used. Causes of blindness were stratified into corneal blindness and 'others'. Odds ratios were computed to determine the odds of developing corneal blindness in each geopolitical region. Tests of significance were set at the 95% level. RESULTS: The total VAS coverage in 2013 was 41.5%. VAS coverage was inequitable. Children with very educated mothers (OR 3.27 p < 0.001), from the south-south region (OR 2.38 p < 0.001) or in the highest wealth quintile (OR 2.81 p < 0.001) had higher odds of receiving VAS. The northwest zone had the lowest VAS coverage and the highest prevalence of corneal blindness. CONCLUSION: Regional and socioeconomic inequities in VAS exist in Nigeria and these may have grave implications for the causes of childhood blindness. The development and implementation of context specific and effective strategies are needed to reduce these inequities in VAS.

An assessment of the trainability of beggars and the destitute in Abakaliki Nigeria: implication for policy on their health, vocational rehabilitation and social reintegration.

BACKGROUND: Begging and destitution constitute serious health and social problems in low and middle-income countries (LMICs). OBJECTIVES: The objective of this study was to assess the trainability of beggars and the destitute in Abakaliki Nigeria in order to provide scientific evidence required for the development of a policy on their health, vocational rehabilitation and social reintegration. METHODS: The study was a cross-sectional descriptive survey of 50 purposively selected beggars and destitute persons identified from motor parks, church cathedrals, market places etc. Data was collected using a structured interviewer-administered questionnaire. Analysis was based on mean rating (MNR), median rating (MDR), and range. Interview of each respondent lasted approximately 20 minutes. RESULTS: Of the 50 respondents who participated in this study, 17 (34%) were females. Most subjects were of age category 31-35 years (30%) and 36-40 years (34%). Fifteen (30%) admitted having sight impairment while 17 (34%) admitted that they were physically challenged. The outcome of the trainability assessment showed relatively high mean ratings (MNRs) ranging from 3.42-4.06 on a scale of 5 points. CONCLUSION: The findings of this study clearly suggest that there is a very high potential for the vocational rehabilitation and social reintegration of beggars and the destitute in the study area.

Medical students' perceptions regarding antibiotics use and antimicrobial resistance in ebonyi state, Nigeria'

BACKGROUND AND OBJECTIVES: Medical students as future doctors have important roles to play in the control of antimicrobial resistance. The aim of this study was to assess the perceptions of medical students regarding antibiotics use and antimicrobial resistance in Ebonyi State, Nigeria. METHODS: A cross-sectional survey was conducted among all the 184 fifth and sixth year medical students in Ebonyi State University, Nigeria using semi-structured, self-administered questionnaires. Proportions, chi square and logistic regression were estimated with Epi Info version 7.2 at 5% level of significance. RESULTS: Respondents were mostly males (62.5%), aged 20-29 years (68.9%) with 60.9% of them in final year. Majority (85.9%) had used antibiotics in the last one year. Most (78.3%) rated themselves to have adequate knowledge on antibiotic use and resistance but only 40.2% respondents had positive perception towards antibiotic use and resistance. Similarly, only 46.7% agreed that hand washing was important in controlling antimicrobial resistance. Majority (53.3%) believed that antibiotics were safe drugs and should be used commonly while only 50.5% disagreed with use of antibiotics as first line treatment for sore throat. Desire for more education on antimicrobial resistance and use was a significant predictor of positive perception (OR 0.36, 95% CI; 0.15-0.87; P=0.024) CONCLUSION: There was poor perception towards antibiotic use and resistance in spite of the high rates of antibiotic consumption and self-rated knowledge onantimicrobialuse. Thereisneedforreorientationofmedicalstudents' perceptions towards antibiotic usage and the role of infection control in curbing antimicrobial resistance

Electrochemical Detection of E. coli O157:H7 in Water after Electrocatalytic and Ultraviolet Treatments Using a Polyguanine-Labeled Secondary Bead Sensor.

The availability of clean drinking water is a significant problem worldwide. Many technologies exist for purifying drinking water, however, many of these methods require chemicals or use simple methods, such as boiling and filtering, which may or may not be effective in removing waterborne pathogens. Present methods for detecting pathogens in point-of-use (POU) sterilized water are typically time prohibitive or have limited ability differentiating between active and inactive cells. This work describes a rapid electrochemical sensor to differentially detect the presence of active Escherichia coli (E. coli) O157:H7 in samples that have been partially or completely sterilized using a new POU electrocatalytic water purification technology based on superradicals generated by defect laden titania (TiO2) nanotubes. The sensor was also used to detect pathogens sterilized by UV-C radiation for a comparison of different modes of cell death. The sensor utilizes immunomagnetic bead separation to isolate active bacteria by forming a sandwich assay comprised of antibody functionalized secondary magnetic beads, E. coli O157:H7, and polyguanine (polyG) oligonucleotide functionalized secondary polystyrene beads as an electrochemical tag. The assay is formed by the attachment of antibodies to active receptors on the membrane of E. coli, allowing the sensor to differentially detect viable cells. Ultravioloet (UV)-C radiation and an electrocatalytic reactor (ER) with integrated defect-laden titania nanotubes were used to examine the sensors’ performance in detecting sterilized cells under different modes of cell death. Plate counts and flow cytometry were used to quantify disinfection efficacy and cell damage. It was found that the ER treatments shredded the bacteria into multiple fragments, while UV-C treatments inactivated the bacteria but left the cell membrane mostly intact.
