High-Throughput CRISPR Screens To Dissect Macrophage- Shigella Interactions

Treatment for shigellosis is becoming increasingly difficult as resistance to antibiotics becomes more prevalent. One way to prevent this significant public health problem from developing into a full-blown crisis is to approach shigellosis intervention from the point of view of the host.

Household Food Insecurity, Dietary Diversity, and Stunting in Sub-Saharan Africa: A Systematic Review

Background: The significant public health problem in Sub-Saharan Africa of household food insecurity is an underlying cause of malnutrition in Sub-Saharan Africa. This study aims to systematically study the association between household food insecurity, dietary diversity, and stunting. Methods: This review was carried out based on the recommendations of PRISMA (2015). We searched the literature in six bibliographic databases: PubMed, EMBASE, Science Direct, Web of Science, Google Scholar, and Scopus. The research was based on studies conducted in Sub-Saharan Africa about household food insecurity, dietary diversity, and stunting and was published between 2009 and 2020. Results: Out of 2398 original articles identified, only 21 articles met the specific requirements of this review. Two-thirds of the articles selected showed that stunting was linked to household food insecurity and dietary diversity. Conclusions: This study found that household food insecurity and dietary diversity are significantly associated with stunting in Sub-Saharan Africa. This review recommends that in order to yield a sustainable fight against childhood malnutrition in Sub-Saharan Africa, reliable guidelines and strategies are needed to address these factors related to malnutrition.

Influenza in the COVID-19 era: principles of modern pharmacotherapy

Influenza is one of the most common infectious diseases and a significant public health problem. Every year, the influenza virus causes 3–5 million severe cases, millions hospitalizations and approximately 650,000 deaths. According to WHO four new influenza strains are projected to circulate in the 2020–2021 epidemic season. Influenza A and B strains are: A/Guangdong-Maonan/ SWL1536/2019 (H1N1) pdm09, A/Hong Kong/2671/2019 (H3N2), B/Washington/02/2019 (Victoria lineage), B/ Phuket/3073/2013 (Yamagata lineage). In this context, the problem of prescribing rational antiviral therapy is particularly importance. COVID-19, along with influenza, is a group of respiratory viral infections, but important differences exist in terms of viral agents and the spread of infection. Important differences include the rate of transmission. The average incubation period and generation time (the time between infecting one person and infecting another) for influenza are shorter. COVID-19 may be more severe, causing complications and deaths in 3–4% of cases. The estimated generation time for COVID 19 is 5-6 days, while for influenza it is 3 days. According to the latest data, the reproductive number, i.e., the number of people who can be infected by one patient, is in the range of 2 to 2.5 in COVID 19, which is higher than in influenza. Only a laboratory test can accurately identify the type of pathogen and distinguish it from influenza and other respiratory viruses. Neuraminidase inhibitors are currently first-line drugs recommended by WHO for the treatment and prevention of influenza.

Assessment of a safe environment in the Samsmu clinics departments in the part of fall prevention

At the present stage of the development of society, the problem of falls on a global scale has become a significant public health problem. WHO has declared the fall “the second leading cause of death from unintentional injury after road traffic injuries” and has identified patient safety as “continuous improvement of practice based on learning from errors and adverse events”. The main principle of ensuring the safety of medical care is the ability to predict the possible consequences that may arise in the process of implementing medical activities.

Anemia of School-Age Children in Primary Schools in Southern China Should Be Paid More Attention despite the Significant Improvement at National Level: Based on Chinese Nutrition and Health Surveillance Data (2016–2017)

Globally, anemia among school-age children (SAC) remains a serious public health problem, impacting their growth, development, educational attainment and future learning potential. National and subnational anemia prevalence among SAC in China has not been assessed recently. Based on data from Chinese Nutrition and Health Surveillance (2016–2017), the current anemia status of SAC in primary schools in China was investigated. Anemia prevalence of SAC in primary schools in China was 4.4%, dropping 63.6% compared with that in 2002. Even though anemia was no longer a significant public health problem at the national level, there were significant spatial disparities of anemia prevalence in different areas: anemia prevalence in 63% of provinces of northern and eastern China has lowered to below 5%, while in provinces of southern China, it was still ranging from 5% to 11.0%, about 3 times of other areas. For those children in southern China, mother’s education level (OR = 1.24, p = 0.04) and father’s education level (OR = 1.27, p = 0.01) below senior high school, eating meat less than 3 times per week (OR = 1.18, p = 0.01) were risk factors of anemia. Older age (OR = 0.35–0.72, p < 0.01) was a protective factor. Targeted interventions should be taken to improve SAC anemia in Southern China, despite anemia of SAC in primary schools no longer being a significant public health problem.

Countering COVID-19 vaccine hesitancy in pregnancy: the “4 Cs”

Despite evidence to support the safety and efficacy of COVID-19 vaccination in pregnancy, and clear recommendations from professional organizations and the CDC for pregnant people to get vaccinated, COVID-19 vaccine hesitancy in pregnancy remains a significant public health problem. The emergence of the highly transmissible B.1.617.2 (Delta) variant among primarily unvaccinated people has exposed the cost of vaccine hesitancy. In this commentary, we explore factors contributing to COVID-19 vaccine hesitancy in pregnancy and potential solutions to overcome them.

Substance Use and Associated Factors Among in School Adolescents in South Africa

Background: Substance use is a significant public health problem worldwide and adversely affects the education system because learners who use substances display behaviours that negatively influence the quality of learning and teaching. The study aimed to determine the educator’s knowledge of the factors contributing to substance use among secondary school learners in the Greater Giyani municipality. Methods: The study employed a descriptive research design, and purposive sampling was applied to select the participants. Data was collected using a structured questionnaire, and data analysis was conducted using the Statistical Package for Social Sciences (SPSS) version 25 programme. Results: The findings show good financial background (69%), more pocket money (67%), high financial difficulties (67%), availability and accessibility of substances (51%), and psychological factors (low self-esteem, depression, and post-traumatic stress disorder) as contributing to learners’ involvement in substance use. Conclusion: Substance use is a matter of serious concern in secondary schools, and several factors are believed to be perpetuating the behaviour. The government should put strict measures in place to ensure the appropriate use of marijuana and for the purpose indicated. Teachers’ inadequate knowledge of contributory factors to substance use by learners could mean that they could not educate them about substance-related harm.

Incidental Laboratory Identification of Brucella melitensis in a case with Pancytopenia

Brucellosis is a bacterial zoonosis usually associated with exposure to infected animals or their products. Although a significant public health problem in India, exact prevalence and distribution are unknown owing to the imprecision of diagnosis and inadequacy of reporting and surveillance. Although the febrile illness is common, its manifestations are highly variable. Bone marrow suppression and consequent pancytopenia have been rarely reported. We present a case of 50 years old female diagnosed with human brucellosis associated with pancytopenia and non-specific clinical presentation, that was diagnosed incidentally on blood and bone-marrow culture. This was confirmed by serological tests like the standard agglutination test. Culture isolation using automated blood culture (e.g. BacT/ALERT), followed by identification using automated identification systems (e.g. MALDI-TOF and VITEK-2) help to reach accurate and timely diagnosis aiding in the management of the patient.

6-Shogaol Mitigates Sepsis-Associated Hepatic Injury through Transcriptional Regulation

Sepsis-associated liver dysfunction presents a significant public health problem. 6-Shogaol is the key bioactive component in dry ginger, which has antioxidant and anti-inflammation capacity. The present study aims to investigate the preventive effect of 6-shogaol on sepsis-induced liver injury. 6-Shogaol was administered to mice for 7 consecutive days before being intraperitoneally injected with lipopolysaccharide (LPS). After 24 h, mice were sacrificed, and biochemical and transcriptomic analyses were performed. Our results demonstrated that 6-shogaol prevented LPS-induced impairment in antioxidant enzymes and elevation in malondialdehyde level in the liver. The hepatic inflammatory response was significantly suppressed by 6-shogaol through suppressing the MAPK/NFκB pathway. RNA-sequencing data analysis revealed that 41 overlapped genes between the LPS vs. control group and 6-shogaol vs. LPS group were identified, among which 36 genes were upregulated, and 5 genes were downregulated for the LPS vs. control group. These overlapped genes are enriched in inflammation-related pathways, e.g., TNF and NFκB. The mRNA expression of the overlapped genes was also verified in the LPS-induced BRL-3A cell model. In summary, 6-shogaol shows great potential as a natural chemopreventive agent to treat sepsis-associated hepatic disorders.
