Knowledge, Awareness and Practice with Antimicrobial Stewardship Programmes among Healthcare Providers in a Ghanaian Tertiary Hospital
Antimicrobial resistance (AMR) is a significant problem in global health today, particularly in low- and middle-income countries (LMICs) where antimicrobial stewardship programmes are yet to be successfully implemented. We established a partnership between AMR pharmacists from a UK NHS hospital and in Ho Teaching Hospital with the aim of enhancing antimicrobial stewardship knowledge and practice among healthcare providers through an educational intervention. We employed a mixed-method approach that included an initial survey on knowledge and awareness before and after training, followed by qualitative interviews with healthcare providers conducted six months after delivery of training. This study was carried out in two phases in Ho Teaching Hospital with healthcare professionals, including pharmacists, medical doctors, nurses and medical laboratory scientists. Ethical approval was obtained prior to data collection. In the first phase, we surveyed 50 healthcare providers, including nurses (33%), pharmacists (29%) and biomedical scientists (23%). Of these, 58% of participants had engaged in continuous professional development on AMR/AMS, and above 95% demonstrated good knowledge on the general use of antibiotics. A total of 18 participants, which included four medical doctors, five pharmacists, four nurses, two midwives and three biomedical scientists, were interviewed in the second phase and demonstrated greater awareness of AMS practices, particularly the role of education for patients, as well as healthcare professionals. We found that knowledge and practice with AMS was markedly improved six months after the training session. There is limited practice of AMS in LMICs; however, through AMR-focused training, we demonstrated improved AMS skills and practice among healthcare providers in Ho Teaching Hospital. There is a need for continuous AMR training sessions for healthcare professionals in resource-limited settings
IgG Seroconversion and Pathophysiology in Severe Acute Respiratory Syndrome Coronavirus 2 Infection.
We investigated the dynamics of seroconversion in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. During March 29–May 22, 2020, we collected serum samples and associated clinical data from 177 persons in London, UK, who had SARS-CoV-2 infection. We measured IgG against SARS-CoV-2 and compared antibody levels with patient outcomes, demographic information, and laboratory characteristics. We found that 2.0%–8.5% of persons did not seroconvert 3–6 weeks after infection. Persons who seroconverted were older, were more likely to have concurrent conditions, and had higher levels of inflammatory markers. Non-White persons had higher antibody concentrations than those who identified as White; these concentrations did not decline during follow-up. Serologic assay results correlated with disease outcome, race, and other risk factors for severe SARS-CoV-2 infection. Serologic assays can be used in surveillance to clarify the duration and protective nature of humoral responses to SARS-CoV-2 infection
Strengthening Foodborne Diseases Surveillance In The Who African Region: An Essential Need For Disease Control And Food Safety Assurance
Several devastating outbreaks of foodborne diseases have been reported
in the African region including acute aflatoxicosis in Kenya in 2004
and bromide poisoning in Angola in 2007. There are concerns about
transmission of multiple antibiotic resistant bacteria and pesticide
residues in foods. The globalization of the food trade which could
increase the spread of food contaminants internationally is an emerging
issue. The new International Health Regulations (IHR) (2005) cover
events of international importance including contaminated food and
outbreaks of foodborne disease. The IHR (2005) and other international
as well as regional agreements require Member States to strengthen
surveillance systems including surveillance for foodborne diseases. WHO
has been supporting countries to strengthen foodborne disease
surveillance since 2003. This paper reports on the work of WHO and
partners in the area of foodborne disease surveillance, the challenges
and opportunities and provides perspectives for the area of its work.
The paper shows that laboratory-based surveillance is the preferred
system for foodborne disease surveillance since it allows early
detection of outbreak strains and identification of risk factors with
laboratory services as the cornerstone. Foodborne disease surveillance
has been included in the revised Integrated Disease Surveillance and
Response (IDSR) Strategy and there are guidelines for use by countries.
WHO in collaboration with partners, especially the Global Food
Infections Network (GFN), has been supporting countries to strengthen
national analytical capacity for foodborne disease surveillance and
research. Training for countries to detect, control and prevent
foodborne and other enteric infections from farm to table has been
conducted. The training for microbiologists and epidemiologists from
public health, veterinary and food sectors involved in isolation,
identification and typing of Salmonella sp, Campylobacter sp.,
Vibrio cholerae , Vibrio sp. and Shigella from human and food
samples have been carried out. Research into specific topics in
microbiology and chemical contaminants has been conducted. Three
institutions in Cameroun, Mali and Nigeria have been designated as
centres of excellence for chemical contaminants. Despite these
significant achievements, a number of challenges remain. Most food
safety programmes and food safety systems remain fragmented resulting
in duplication of efforts and inefficient use of resources; and most
laboratories in the African Region are poorly resourced. In countries
where facilities exist, there is underutilization and lack of synergy
among laboratories. Countries should, therefore, conduct audits of
existing laboratories to determine their strengths and weaknesses and
strategize as appropriate. It is also imperative to continue to
strengthen partnerships and forge new ones and increase resources for
food safety, in general, and for foodborne disease surveillance, in
particular, and continue capacity building, both human and
institutional

Impact of the 2008 Beijing Olympics on the risk of pregnancy complications.
Taking advantage of the natural experiment of the 2008 Beijing Olympics (August 8 to September 24), when air pollution levels decreased by 13% to 60%, the authors assessed whether having ≥1 pregnancy month during the Olympics was associated with decreased risks of hypertensive disorders (HDs) and/or fetal-placental conditions (FPCs). Singleton births to mothers with ≥1 pregnancy month in 2008 or 2009 (N = 56,155) were included. Using generalized additive models, the authors estimated the risk of HDs and FPCs associated with (1) the 2008 Olympics compared with the same dates in 2009, and (2) increased mean ambient PM10 (particulate matter with an aerodynamic diameter <10 μm), NO2 (nitrogen dioxide), and SO2 (sulfur dioxide) concentrations during each trimester. However, no association between HDs or FPCs and having any trimester during the 2008 Olympic period was found. This may, in part, be due to a small number of pregnancy complications in this population

Differences in Birth Weight Associated with the 2008 Beijing Olympics Air Pollution Reduction: Results from a Natural Experiment.
BackgroundPrevious studies have reported decreased birth weight associated with increased air pollutant concentrations during pregnancy. However, it is not clear when during pregnancy increases in air pollution are associated with the largest differences in birth weight.ObjectivesUsing the natural experiment of air pollution declines during the 2008 Beijing Olympics, we evaluated whether having specific months of pregnancy (i.e., 1st…8th) during the 2008 Olympics period was associated with larger birth weights, compared with pregnancies during the same dates in 2007 or 2009.MethodsUsing n = 83,672 term births to mothers residing in four urban districts of Beijing, we estimated the difference in birth weight associated with having individual months of pregnancy during the 2008 Olympics (8 August-24 September 2008) compared with the same dates in 2007 and 2009. We also estimated the difference in birth weight associated with interquartile range (IQR) increases in mean ambient particulate matter ≤ 2.5 μm in aerodynamic diameter (PM2.5), sulfur dioxide (SO2), nitrogen dioxide (NO2), and carbon monoxide (CO) concentrations during each pregnancy month.ResultsBabies whose 8th month of gestation occurred during the 2008 Olympics were, on average, 23 g larger (95% CI: 5 g, 40 g) than babies whose 8th month occurred during the same calendar dates in 2007 or 2009. IQR increases in PM2.5 (19.8 μg/m3), CO (0.3 ppm), SO2 (1.8 ppb), and NO2 (13.6 ppb) concentrations during the 8th month of pregnancy were associated with 18 g (95% CI: -32 g, -3 g), 17 g (95% CI: -28 g, -6 g), 23 g (95% CI: -36 g, -10 g), and 34 g (95% CI: -70 g, 3 g) decreases in birth weight, respectively. We did not see significant associations for months 1-7.ConclusionsShort-term decreases in air pollution late in pregnancy in Beijing during the 2008 Summer Olympics, a normally heavily polluted city, were associated with higher birth weight.CitationRich DQ, Liu K, Zhang J, Thurston SW, Stevens TP, Pan Y, Kane C, Weinberger B, Ohman-Strickland P, Woodruff TJ, Duan X, Assibey-Mensah V, Zhang J. 2015.

Double Entry Bookkeeping and the Distributional Properties of a Firm's Financial Ratios
Our purpose here is to assess whether the innate properties of the double entry bookkeeping system are such that financial ratios, calculated from the balance sheet summary measures implied by it, will be generated by distributional forms with non-convergent moments. Our analysis begins with a brief summary of some important analytical properties of the debt and equity components of the double entry bookkeeping system. We then use these to determine the time series and distributional properties of the debt to equity ratio itself. Our analysis shows that even when the evolution of balance sheet summary measures like debt and equity can be described by 'well behaved' distributional processes, there is a distinct possibility that ratios derived from them will evolve in terms of distributional forms with non-convergent moments. We argue that this has serious implications for parameter estimation as well as the integrity of the regression and/or discriminant procedures which underscore bankruptcy and financial distress prediction models based on financial ratios derived from the double entry bookkeeping system.
