ABSTRACT Objective The aim of this study was to use a wavelet technique to determine whether the number of suicides is similar between developed and emerging countries. Methods Annual data were obtained from World Health Organization (WHO) reports from 1986 to 2015. Discrete nondecimated wavelet transform was used for the analysis, and the Daubechies wavelet function was applied with five-level decomposition. Regarding clustering, energy (variance) was used to analyze the clusters and visualize the clustering process. We constructed a dendrogram using the Mahalanobis distance. The number of groups was set using a specific function in the R program. Results The cluster analysis verified the formation of four groups as follows: Japan, the United States and Brazil were distinct and isolated groups, and other countries (Austria, Belgium, Chile, Israel, Mexico, Italy and the Netherlands) constituted a single group. Conclusion The methods utilized in this paper enabled a detailed verification of countries with similar behaviors despite very distinct socioeconomic, geographic and climate characteristics.

Sickle cell disease (SCD) is a genetic disorder that poses a serious health threat in tropical Africa, which the World Health Organization has declared a public health priority. Its persistence in human populations has been attributed to the resistance it provides to Plasmodium falciparum malaria in its heterozygous state, called sickle cell trait (SCT). Because of migration, SCT is becoming common outside tropical countries: It is now the most important genetic disorder in France, affecting one birth for every 2,400, and one of the most common in the United States. We assess the strength of the association between SCT and malaria, using current data for both SCT and malaria infections. A total of 3,959 blood samples from 195 villages distributed over the entire Republic of Gabon were analyzed. Hemoglobin variants were identified by using HPLCy (HPLC). Infections by three species of Plasmodium were detected by PCR followed by sequencing of a 201-bp fragment of cytochrome b. An increase of 10% in P. falciparum malaria prevalence is associated with an increase by 4.3% of SCT carriers. An increase of 10 y of age is associated with an increase by 5.5% of SCT carriers. Sex is not associated with SCT. These strong associations show that malaria remains a selective factor in current human populations, despite the progress of medicine and the actions undertaken to fight this disease. Our results provide evidence that evolution is still present in humans, although this is sometimes questioned by scientific, political, or religious personalities.

IN THE summary of the report of the Expert Committee on Prematurity of the World Health Organization, published in this column in February 1951, Dr. Ethel Dunham indicated the concern of the Expert Committee in regard to uniformity of information on the incidence and mortality of prematurity. The need for uniformity is particularly urgent in a field where there are so many intrinsic variable factors. It has been shown time and again that the ability of a premature infant to survive, under the best of care, is closely correlated with the birth weight, which in itself reflects the stage of maturity. In turn, the stage of maturity at a given weight is affected by sex, race, and whether the child is a single or one of a multiple birth. Uniformly, at a particular stage of maturity, male infants are larger than female, single births are larger than multiple births and, in the United States, white babies are larger than Negro babies. These considerations underline the danger of misinterpretation of so-called over-all rates for the incidence of prematurity and for the mortality of premature infants. For example, at any given weight, Negro premature infants are probably more mature and consequently have a better chance of surviving.

COVID-19 vaccine passports run the risk of creating a divided society where social privileges or restrictions based on “fitness” lead to discrimination based on immunization status. Individuals have a strong right to be free of coercion to take a COVID-19 vaccine, and we should be very leery of further invasion of private medical decisions. These concerns are shared both internationally and in the United States, and the World Health Organization, the Biden administration, and many US governors oppose COVID-19 vaccine credentials. In addition, regulations for COVID-19 vaccine credentials face practical barriers, including lack of access globally, especially among the poor; and lack of scientific data on the efficacy of these vaccines.

In most high-income countries, including Canada, the share of births by Caesarean section (C‑section) has risen over the past decades to far exceed World Health Organization recommendations of the proportion justified on medical grounds (15 percent). Although unnecessary C-sections represent an important cost for health care systems, they are not associated with clear benefits for the mother and the child and can sometimes represent additional risks. Drawing on administrative records of nearly four million births in Canada, as well as macro data from the United States and Australia, we provide a comprehensive account of rising C-section rates. We explicitly consider the contributions of the main factors brought forward in the policy literature, including changing characteristics of mothers, births, and physicians as well as changing financial incentives for C-section deliveries. These factors account for at most one-half of the increase in C-section rates. The majority of the remaining increase in C-sections over the period 1994–2011 occurred in the early 2000s. We suggest that some event or shock in the early 2000s is likely the primary determinant of the recent strong increase in the C-section rate in Canada.

BACKGROUND Misinformation about COVID-19 has presented challenges to public health authorities during pandemics. Understanding the prevalence and type of misinformation across contexts offers a way to understand the discourse around COVID-19 while informing potential countermeasures. OBJECTIVE The aim of the study was to study COVID-19 content on two prominent microblogging platform, Twitter, based in the United States, and Sina Weibo, based in China, and compare the content and relative prevalence of misinformation to better understand public discourse of public health issues across social media and cultural contexts. METHODS A total of 3,579,575 posts were scraped from both Weibo and Twitter, focusing on content from January 30th, 2020, when the World Health Organization (WHO) declared COVID-19 a “Public Health Emergency of International Concern” and February 6th, 2020. A 1% random sample of tweets that contained both the English keywords “coronavirus” and “covid-19” and the equivalent Chinese characters was extracted and analyzed based on changes in the frequencies of keywords and hashtags. Misinformation on each platform was compared by manually coding and comparing posts using the World Health Organization fact-check page to adjudicate accuracy of content. RESULTS Both platforms posted about the outbreak and transmission but posts on Sina Weibo were less likely to reference controversial topics such as the World Health Organization and death and more likely to cite themes of resisting, fighting, and cheering against the coronavirus. Misinformation constituted 1.1% of Twitter content and 0.3% of Weibo content. CONCLUSIONS Quantitative and qualitative analysis of content on both platforms points to cross-platform differences in public discourse surrounding the pandemic and informs potential countermeasures for online misinformation.

Coronavirus disease 2019 (COVID-19), which causes severe airway problems, first emerged in the Chinese city of Wuhan. The virus led to a pandemic that affected the entire world. COVID-19 affects not only health, but also economic and social life. The emergence of this pandemic has led to health systems across the world being questioned. The aim of this study was to assess the adequacy of world health systems in the face of this pandemic. Twelve countries were selected and analyzed in the study. The choice of these countries was determined by the number of COVID-19 cases and deaths. Information concerning health systems and COVID-19 was obtained from Organization for Economic Co-operation and Development 2018, World Health Organization 2020 and Deep Knowledge Group data and was subjected to statistical analysis. According to the analysis, the country with the highest investment in health expenditures is the United States (10586 US dollars/capita), and Germany stands out as the best in health services. Another finding is the first and second wave of COVID-19 was identified as the USA with the highest case and death rate (First wave cases 1.942.363 and deaths 110.514; second wave cases at 7.419.230 and deaths 2.09.450). As a result of the meta-analysis, it is revealed that only socio-economic power is not enough, countries with good health systems are more successful in the pandemic. In addition, the analysis once again reveal how important health systems are in the face of such a pandemic.

Antibiotic fixed dose combinations (FDCs) can have clinical advantages such as improving effectiveness and adherence to therapy. However, high use of potentially inappropriate FDCs has been reported, with implications for antimicrobial resistance (AMR) and toxicity. We used a pharmaceutical database, IQVIA-Multinational Integrated Data Analysis System (IQVIA-MIDAS®), to estimate sales of antibiotic FDCs from 75 countries in 2015. Antibiotic consumption was estimated using standard units (SU), defined by IQVIA as a single tablet, capsule, ampoule, vial or 5ml oral suspension. For each FDC antibiotic, the approval status was assessed by either registration with the United States Food and Drug Administration (US FDA) or inclusion on the World Health Organization (WHO) Essential Medicines List (EML). A total of 119 antibiotic FDCs were identified, contributing 16.7 x 109 SU, equalling 22% of total antibiotic consumption in 2015. The most sold antibiotic FDCs were amoxicillin-clavulanic acid followed by trimethoprim/sulfamethoxazole and ampicillin/cloxacillin. The category with the highest consumption volume was aminopenicillin/β-lactamase inhibitor +/- other agents. The majority of antibiotic FDCs (92%; 110/119) were not approved by the US FDA. Of these, the most sold were ampicillin/cloxacillin, cefixime/ofloxacin and metronidazole/spiramycin. More than 80% (98/119) of FDC antibiotics were not compatible with the 2017 WHO EML. The countries with the highest numbers of FDC antibiotics were India (80/119), China (25/119) and Vietnam (19/119). There is high consumption of FDC antibiotics globally, particularly in middle-income countries. The majority of FDC antibiotic were not approved by either US FDA or WHO EML. International initiatives such as clear guidance from the WHO EML on which FDCs are not appropriate may help to regulate the manufacturing and sales of these antibiotics.

Background. The availability of poor-quality drugs on the drug market might favor the ineffectiveness of the drug and/antimicrobial resistance. Aim. To evaluate the quality of similar batches of ethambutol hydrochloride tablets available in different governmental health facilities of Jimma town, southwest Ethiopia. Methods. The World Health Organization checklist was used to inspect the storage area of health facilities and check medicines for the sign of counterfeit. The test was conducted as per the United States Pharmacopeia on six similar batches of ethambutol hydrochloride sampled from different governmental health facilities. Data were analyzed using SPSS version 20, and one-way ANOVA was used for comparing the dissolution profile and weight variation of batches. Results. Three health facilities did not comply with the storage area specifications for pharmaceuticals. No batches have shown any sign of counterfeit. All of the tablet batches tested complied with USP specifications for weight variation, percentage purity, and dissolution test. Conclusions and Recommendation. The entire tablet batches complied with the World Health Organization specification for packaging and labelling of pharmaceuticals. All tablet batches complied with the test for weight variation, purity of drug substance, and dissolution. Since some health facilities did not comply with at least one specification for storage of pharmaceuticals, regulatory agencies and stack holders are advised to inspect the health facilities to ensure appropriate storage of pharmaceuticals in health facilities.

AbstractBackgroundNumerous non-pharmaceutical interventions (NPIs) were taken worldwide to contain the spread of the COVID-19 pandemic. We aimed at providing an overview of randomized trials assessing NPIs to prevent COVID-19.MethodsWe included all randomized trials assessing NPIs to prevent COVID-19 in any country and setting registered in ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform using the COVID-evidence platform (until 17 August 2021). We searched for corresponding publications in MEDLINE/PubMed, Google Scholar, the Living Overview of Evidence platform (L-OVE), and the Cochrane COVID-19 registry as well as for results posted in registries.ResultsWe identified 41 randomized trials. Of them, 11 were completed (26.8%) including 7 with published results. The 41 trials planned to recruit a median of 1,700 participants (IQR, 588 to 9,500, range 30 to 35,256,399) with a median planned duration of 8 months (IQR, 3 to 14, range 1 to 24). Most came from the United States (n=11, 26.8%). The trials mostly assessed protective equipment (n=11, 26.8%), COVID-19-related information and education programs (n=9, 22.0%), access to mass events under specific safety measures (n=5, 12.2%), testing and screening strategies (n=5, 12.2%), and hygiene management (n=5, 12.2%).ConclusionsWorldwide, 41 randomized trials assessing NPIs have been initiated with published results available to inform policy decisions for only 7 of them. A long-term research agenda including behavioral, environmental, social, and systems level interventions is urgently needed to guide policies and practices in the current and future public health emergencies.

In March and April 2009, a new strain of influenza A(H1N1) virus has been isolated in Mexico and the United States. Since the initial reports more than 10,000 cases have been reported to the World Health Organization, all around the world. Several hundred isolates have already been sequenced and deposited in public databases. We have studied the genetics of the new strain and identified its closest relatives through a cluster analysis approach. We show that the new virus combines genetic information related to different swine influenza viruses. Segments PB2, PB1, PA, HA, NP and NS are related to swine H1N2 and H3N2 influenza viruses isolated in North America. Segments NA and M are related to swine influenza viruses isolated in Eurasia.
