Resource availability and capacity to implement multi-stranded cholera interventions in the north-east region of Nigeria
Background:
Limited healthcare facility (HCF) resources and capacity to implement multi-stranded cholera interventions (water, sanitation, and hygiene (WASH), surveillance, case management, and community engagement) can hinder the actualisation of the global strategic roadmap goals for cholera control, especially in settings made fragile by armed conflicts, such as the north-east region of Nigeria. Therefore, we aimed to assess HCF resource availability and capacity to implement these cholera interventions in Adamawa and Bauchi States in Nigeria as well as assess their coordination in both states and Abuja where national coordination of cholera is based.
Methods:
We conducted a cross-sectional survey using a face-to-face structured questionnaire to collect data on multi-stranded cholera interventions and their respective indicators in HCFs. We generated scores to describe the resource availability of each cholera intervention and categorised them as follows: 0–50 (low), 51–70 (moderate), 71–90 (high), and over 90 (excellent). Further, we defined an HCF with a high capacity to implement a cholera intervention as one with a score equal to or above the average intervention score.
Results:
One hundred and twenty HCFs (55 in Adamawa and 65 in Bauchi) were surveyed in March 2021, most of which were primary healthcare centres (83%; 99/120). In both states, resource availability for WASH indicators had high to excellent median scores; surveillance and community engagement indicators had low median scores. Median resource availability scores for case management indicators ranged from low to moderate. Coordination of cholera interventions in Adamawa State and Abuja was high but low in Bauchi State. Overall, HCF capacity to implement multi-stranded cholera interventions was high, though higher in Adamawa State than in Bauchi State.
Conclusions:
The study found a marked variation in HCF resource availability and capacity within locations and by cholera interventions and identified cholera interventions that should be prioritised for strengthening as surveillance and laboratory, case management, and community engagement. The findings support adopting a differential approach to strengthening cholera interventions for better preparedness and response to cholera outbreaks

The Effectiveness of Alcohol Screening and Brief Intervention in Emergency Departments: A Multicentre Pragmatic Cluster Randomized Controlled Trial
BACKGROUND:
Alcohol misuse is common in people attending emergency departments (EDs) and there is some evidence of efficacy of alcohol screening and brief interventions (SBI). This study investigated the effectiveness of SBI approaches of different intensities delivered by ED staff in nine typical EDs in England: the SIPS ED trial.
METHODS AND FINDINGS:
Pragmatic multicentre cluster randomized controlled trial of SBI for hazardous and harmful drinkers presenting to ED. Nine EDs were randomized to three conditions: a patient information leaflet (PIL), 5 minutes of brief advice (BA), and referral to an alcohol health worker who provided 20 minutes of brief lifestyle counseling (BLC). The primary outcome measure was the Alcohol Use Disorders Identification Test (AUDIT) status at 6 months. Of 5899 patients aged 18 or more presenting to EDs, 3737 (63·3%) were eligible to participate and 1497 (40·1%) screened positive for hazardous or harmful drinking, of whom 1204 (80·4%) gave consent to participate in the trial. Follow up rates were 72% (n?=?863) at six, and 67% (n?=?810) at 12 months. There was no evidence of any differences between intervention conditions for AUDIT status or any other outcome measures at months 6 or 12 in an intention to treat analysis. At month 6, compared to the PIL group, the odds ratio of being AUDIT negative for brief advice was 1·103 (95% CI 0·328 to 3·715). The odds ratio comparing BLC to PIL was 1·247 (95% CI 0·315 to 4·939). A per protocol analysis confirmed these findings.
CONCLUSIONS:
SBI is difficult to implement in typical EDs. The results do not support widespread implementation of alcohol SBI in ED beyond screening followed by simple clinical feedback and alcohol information, which is likely to be easier and less expensive to implement than more complex interventions

Fine-scale detection of population-specific linkage disequilibrium using haplotype entropy in the human genome
<p>Abstract</p> <p>Background</p> <p>The creation of a coherent genomic map of recent selection is one of the greatest challenges towards a better understanding of human evolution and the identification of functional genetic variants. Several methods have been proposed to detect linkage disequilibrium (LD), which is indicative of natural selection, from genome-wide profiles of common genetic variations but are designed for large regions.</p> <p>Results</p> <p>To find population-specific LD within small regions, we have devised an entropy-based method that utilizes differences in haplotype frequency between populations. The method has the advantages of incorporating multilocus association, conciliation with low allele frequencies, and independence from allele polarity, which are ideal for short haplotype analysis. The comparison of HapMap SNPs data from African and Caucasian populations with a median resolution size of ~23 kb gave us novel candidates as well as known selection targets. Enrichment analysis for the yielded genes showed associations with diverse diseases such as cardiovascular, immunological, neurological, and skeletal and muscular diseases. A possible scenario for a selective force is discussed. In addition, we have developed a web interface (ENIGMA, available at <url>http://gibk21.bse.kyutech.ac.jp/ENIGMA/index.html</url>), which allows researchers to query their regions of interest for population-specific LD.</p> <p>Conclusion</p> <p>The haplotype entropy method is powerful for detecting population-specific LD embedded in short regions and should contribute to further studies aiming to decipher the evolutionary histories of modern humans.</p
Patient characteristics associated with COVID-19 positivity and fatality in Nigeria: retrospective cohort study
Objective: Despite the increasing disease burden, there is
a dearth of context-specific evidence on the risk factors for
COVID-19 positivity and subsequent death in Nigeria. Thus,
the study objective was to identify context-specific factors
associated with testing positive for COVID-19 and fatality
in Nigeria.
Design Retrospective cohort study.
Setting: COVID-19 surveillance and laboratory centres in
36 states and the Federal Capital Territory reporting data to
the Nigeria Centre for Disease Control.
Participants: Individuals who were investigated for SARSCoV-2 using real-time PCR testing during the study period
27 February–8 June 2020.
Methods: COVID-19 positivity and subsequent mortality.
Multivariable logistic regression analyses were performed
to identify factors independently associated with both
outcome variables, and findings are presented as adjusted
ORs (aORs) and 95% CIs.
Results: A total of 36 496 patients were tested for
COVID-19, with 10 517 confirmed cases. Of 3215
confirmed cases with available clinical outcomes, 295
died. Factors independently associated with COVID-19
positivity were older age (p value for trend<0.0001), male
sex (aOR 1.11, 95%CI 1.04 to 1.18) and the following
presenting symptoms: cough (aOR 1.23, 95% CI 1.13 to
1.32), fever (aOR 1.45, 95% CI 1.45 to 1.71), loss of smell
(aOR 7.78, 95% CI 5.19 to 11.66) and loss of taste (aOR
2.50, 95% CI 1.60 to 3.90). An increased risk of mortality
following COVID-19 was observed in those aged ≥51
years, patients in farming occupation (aOR 7.56, 95% CI
1.70 to 33.53) and those presenting with cough (aOR 2.06,
95% CI 1.41 to 3.01), breathing difficulties (aOR 5.68, 95%
CI 3.77 to 8.58) and vomiting (aOR 2.54, 95% CI 1.33 to
4.84).
Conclusion: The significant risk factors associated with
COVID-19 positivity and subsequent mortality in the
Nigerian population are similar to those reported in studies
from other countries and should guide clinical decisions for
COVID-19 testing and specialist care referrals

Optimality and distortionary lobbying: regulating tobacco consumption
We examine policies directed at regulating tobacco consumption through three types of instruments: (i) an excise tax hindering consumption by increasing the price of cigarettes, (ii) prevention programs helping consumers to make choices that are more time consistent when trading-off the current pleasure from smoking and its future health harms, and (iii) smoking bans directly restricting consumption. First, on normative grounds, we focus on the optimal design of public policies maximizing the economy’s surplus. Second, in a positive perspective, we investigate how the lobbying activities of the tobacco industry, of smokers, and of anti-tobacco organizations may distort government intervention
COVID-19 mortality rate and its associated factors during the first and second waves in Nigeria
COVID-19 mortality rate has not been formally assessed in Nigeria. Thus, we aimed to address this gap and identify associated mortality risk factors during the first and second waves in Nigeria. This was a retrospective analysis of national surveillance data from all 37 States in Nigeria between February 27, 2020, and April 3, 2021. The outcome variable was mortality amongst persons who tested positive for SARS-CoV-2 by Reverse-Transcriptase Polymerase Chain Reaction. Incidence rates of COVID-19 mortality was calculated by dividing the number of deaths by total person-time (in days) contributed by the entire study population and presented per 100,000 person-days with 95% Confidence Intervals (95% CI). Adjusted negative binomial regression was used to identify factors associated with COVID-19 mortality. Findings are presented as adjusted Incidence Rate Ratios (aIRR) with 95% CI. The first wave included 65,790 COVID-19 patients, of whom 994 (1∙51%) died; the second wave included 91,089 patients, of whom 513 (0∙56%) died. The incidence rate of COVID-19 mortality was higher in the first wave [54∙25 (95% CI: 50∙98–57∙73)] than in the second wave [19∙19 (17∙60–20∙93)]. Factors independently associated with increased risk of COVID-19 mortality in both waves were: age ≥45 years, male gender [first wave aIRR 1∙65 (1∙35–2∙02) and second wave 1∙52 (1∙11–2∙06)], being symptomatic [aIRR 3∙17 (2∙59–3∙89) and 3∙04 (2∙20–4∙21)], and being hospitalised [aIRR 4∙19 (3∙26–5∙39) and 7∙84 (4∙90–12∙54)]. Relative to South-West, residency in the South-South and North-West was associated with an increased risk of COVID-19 mortality in both waves. In conclusion, the rate of COVID-19 mortality in Nigeria was higher in the first wave than in the second wave, suggesting an improvement in public health response and clinical care in the second wave. However, this needs to be interpreted with caution given the inherent limitations of the country’s surveillance system during the study
