Background: The lower Saint Lawrence river region (LSLRR), in Quebec, has a 10-fold higher incidence of Q fever compared to the provincial rate. This study aimed to review clinical cases and the Q fever risk exposure in this region. Methods: Data were retrieved from microbiology laboratory, medical records from Rimouski Regional Hospital and Public Health reports between 1991 and 2018. They were analyzed with Epi Info 7.2.2.6. Patients with confirmed acute, probable acute, and chronic Q fever were classified using standard case definitions and mapped according to the postal code, to assess the correlation between cases and sheep distribution. Results: Out of 295 cases, 258 were included (241 confirmed acute, seven probable acute, 10 chronic). Median age was 49 years, 76% were male. For acute cases, the prominent symptoms were fever (99%), headache (83%), chills (80%), sweating (72%), myalgia (69%), and fatigue (67%). Clinical presentation was mostly febrile syndrome with mild hepatitis (84%). A seasonal peak was observed from May to July (56% of acute cases). Most cases (56%) occurred within the two counties where sheep production was highest. Exposure to sheep was prominent 93%, including 64% direct contact (15% shepherds, 49% sheepfold visitors), 14% indirect contact, and 15% sheepfold neighbors. Conclusions: To our knowledge, this is one of the largest retrospective studies of Q fever cases reported in Canada. Q fever in Quebec LSLRR is associated mainly with sheep exposure. Fever and hepatitis were the most common manifestations. Preventive measures should be considered in this region to protect sheepfold workers, visitors, and their neighbors.

Authors: Volkov Sergey 
Published: August 2023

In March, Center for Russian-African Relations and Foreign Policy of African Countries of the Institute for African Studies (Russian Academy of Sciences) held a conference “Africa – the Rising Center of an Emerging Multipolar World”. The conference took place during a period of sharp aggravation of the international situation, which required for Russia to revise the directions of its foreign policy with the focus on some countries, in particular, the countries of Africa.
The event held in the format of a videoconference was attended by scientists of the IAfr RAS, MGIMO University, RISI, Institute of Economics (Academy of Sciences of Belarus), Research Economic Institute of the Ministry of Economy (Republic of Belarus), teachers and students of Patrice Lumumba RUDN University, Moscow State University, TISBI University of Management (Kazan, Russia), Samara State University of Economics.
The role and place of African countries in the system of international relations and in strategies of the main centers of power, the African policy of the world’s leading players, as well as the state and prospects of Russian- and Belarusian-African cooperation in the context of a sharp aggravation of the international situation and tough economic sanctions imposed by the West on Russia and Belarus were discussed. The speeches contained recommendations on strengthening both countries mutually beneficial partnership with African states, which may be used by government organizations and business community.

Background: Comprising nearly 35% of brain lipids, polyunsaturated fatty acids (PUFA) are essential for optimal brain function. However, the role of PUFA on cognitive health outcomes later in life is largely unknown. Objective: We investigated prospective associations of plasma phospholipid omega-3 (ALA [18 : 3], EPA [20 : 5], DPA [22 : 5], DHA [22 : 6]) and omega-6 (LA [18 : 2], AA [20 : 4]) PUFA with cognitive decline, risk of cognitive impairment and dementia among adults aged≥65 years in the Cardiovascular Health Study. Methods: Circulating fatty acid concentrations were measured serially at baseline (1992/1993), 6 years, and 13 years later. Cognitive decline and impairment were assessed using the 100-point Modified Mini-Mental State Examination (3MSE) up to 7 times. Clinical dementia was identified using adjudicated neuropsychological tests, and ICD-9 codes. Results: Among 3,564 older adults free of stroke and dementia at baseline, cognitive function declined annually by approximately -0.5 3MSE points; 507 participants developed cognitive impairment and 499 dementia over up to 23 years of follow-up. In multivariable models, higher circulating arachidonic acid (AA) concentrations were associated with slower cognitive decline and lower dementia risk, with associations growing stronger with greater length of follow-up (hazard ratio [HR,95% CI] of dementia per interquintile range, 0.74 [0.56-0.97] at 5 years, and 0.53 [0.37-0.77] at 15 years). Circulating docosapentaenoic (DPA) concentrations were associated with slower cognitive decline and lower risk of cognitive impairment (extreme-quintile HR, 0.72 [95% CI: 0.55, 0.95]). Findings were generally null or inconsistent for other omega-3 or omega-6 PUFA. Conclusion: Circulating AA and DPA, but not other PUFA, are associated with slower rate of cognitive decline and lower risk of dementia or cognitive impairment later in life.

Background: Atrophy of cholinergic basal forebrain (BF) nuclei is a frequent finding in magnetic resonance imaging (MRI) volumetry studies that examined patients with prodromal or clinical Alzheimer’s disease (AD), but less clear for individuals in earlier stages of the clinical AD continuum. Objective: To examine BF volume reductions in subjective cognitive decline (SCD) participants with AD pathologic changes. Methods: The present study compared MRI-based BF volume measurements in age- and sex-matched samples of N = 24 amyloid-positive and N = 24 amyloid-negative SCD individuals, based on binary visual ratings of Florbetaben positron emission tomography (PET) measurements. Additionally, we assessed associations of BF volume with cortical amyloid burden, based on semiquantitative Centiloid (CL) analyses. Results: Group differences approached significance for BF total volume ( p = 0.061) and the Ch4 subregion ( p = 0.059) only, showing the expected relative volume reductions for the amyloid-positive subgroup. There were also significant inverse correlations between BF volumes and CL values, which again were most robust for BF total volume and the Ch4 subregion. Conclusions: The results are consistent with the hypothesis that amyloid-positive SCD individuals, which are considered to represent a transitional stage on the clinical AD continuum, already show incipient alterations of BF integrity. The negative association with a continuous measure of cortical amyloid burden also suggests that this may reflect an incremental process. Yet, further research is needed to evaluate whether BF changes already emerge at “grey zone” levels of amyloid accumulation, before amyloidosis is reliably detected by PET visual readings.

Published: August 2023

Background: Multiple algorithms with variable performance have been developed to identify dementia using combinations of billing codes and medication data that are widely available from electronic health records (EHR). If the characteristics of misclassified patients are clearly identified, modifying existing algorithms to improve performance may be possible. Objective: To examine the performance of a code-based algorithm to identify dementia cases in the population-based Mayo Clinic Study of Aging (MCSA) where dementia diagnosis (i.e., reference standard) is actively assessed through routine follow-up and describe the characteristics of persons incorrectly categorized. Methods: There were 5,316 participants (age at baseline (mean (SD)): 73.3 (9.68) years; 50.7% male) without dementia at baseline and available EHR data. ICD-9/10 codes and prescription medications for dementia were extracted between baseline and one year after an MCSA dementia diagnosis or last follow-up. Fisher’s exact or Kruskal-Wallis tests were used to compare characteristics between groups. Results: Algorithm sensitivity and specificity were 0.70 (95% CI: 0.67, 0.74) and 0.95 (95% CI: 0.95, 0.96). False positives (i.e., participants falsely diagnosed with dementia by the algorithm) were older, with higher Charlson comorbidity index, more likely to have mild cognitive impairment (MCI), and longer follow-up (versus true negatives). False negatives (versus true positives) were older, more likely to have MCI, or have more functional limitations. Conclusions: We observed a moderate-high performance of the code-based diagnosis method against the population-based MCSA reference standard dementia diagnosis. Older participants and those with MCI at baseline were more likely to be misclassified.

Abstract
Dysmenorrhea is a reproductive health problem that often occurs in adolescent girls. The purpose of this study was to analyze the risk factors that influence the incidence of primary dysmenorrhea in adolescent girls during the Covid-19 pandemic. The research method used a cross-sectional research design. The number of respondents was 130 adolescent girls, who had experienced dysmenorrhea with consecutive sampling as the sample. Data was collected using the GPAQ (2016) questionnaire, PSQI, and NRS. The results of this study showed that the variables were family history (p=0.003; OR=3.380; 95% CI=1.520–7.518), sleep quality (p=0.025; OR= 2.836; 95% CI=1.138-7.070), and age at menarche. (p=0.039; OR= 1.933; 95% CI=1.035-3.609) had a significant effect on the incidence of primary dysmenorrhea in adolescent girls. The physical activity did not have a significant effect on the incidence of primary dysmenorrhea (p=0.307; OR= 0.671; CI 95% = 0.312–1.444). The most influential factor in the incidence of primary dysmenorrhea during the Covid-19 pandemic is a family history of primary dysmenorrhea. Health education about sleep quality needs to be delivered to adolescent girls so that the incidence of primary dysmenorrhea during the Covid-19 pandemic can be minimized.

Phytochemical Molecules Binding with the Proteins of Mycolic Acid Synthesis Pathway of Mycobacterium tuberculosis
Authors: Gaur Rishabh , Anand Praveen Kumar 
Published: August 2023

Resistance against anti-tubercular drugs is a significant problem. This elucidates the need for novel drug targets. Altering and targeting the enzymes involved in cell wall synthesis led to fatal damage to the bacterial cell. Mycolic acids are critically responsible for the virulence of Mycobacterium Tuberculosis. This pathway represents an essential reservoir of novel targets for developing new TB drugs. The study aims to identify phytochemicals with the capacity to bind with enzymes of mycolic acid synthesis pathways. This study shows the interaction between phytochemicals and proteins responsible for mycolic acid synthesis is shown through bioinformatics & molecular docking tools. Docking showed binding affinity between protein molecules of the mycolic acid synthesis pathway and ligand molecules in the study. PKS13 (polyketide synthase) interacts with the ligand beta-amyrin acetate with a vina score of -7.1 Kcal/mol. At the same time, its binding energy with Piperine is -6.8 Kcal/mol. DprE1 (Decaprenylphosphoryl-bet-D-ribose-2-epimerase), the other protein docked with beta-amyrin acetate, showed a vina score of -9.7 Kcal/mol binding energy. Piperine with DprE1 exhibits interaction with a score of -8.3 Kcal/mol. Beta-amyrin acetate is docked with a score of -6.9 Kcal/mol against KasA (Beta-ketoacyl-acyl carrier protein synthase). On the other hand, Piperine with KasA gave a result of -7.0 Kcal/mol. Piperine and Beta-amyrin acetate binds to PKS13, DprE1 & KasA protein/enzymes responsible for mycolic acid biosynthesis.

Background: This study investigated NHS Health Check programme delivery before and after the Covid-19 pandemic response, with a focus on support services and referral methods available to Health Check attendees. The NHS Health Check is an important part of England’s Cardiovascular Disease (CVD) prevention programme. Methods: Public health commissioners from all 151 local authorities responsible for commissioning the NHS Health Check programme were surveyed in 2021, using an online questionnaire to capture detail about programme delivery, changes in delivery because of the pandemic response, and monitoring of programme outcomes. Four-point rating scales were used to obtain level of confidence in capacity, accessibility and usage of follow-on support services for Health Check attendees. A typology of programme delivery was developed, and associations between delivery categories and a range of relevant variables were assessed using one-way analysis of variance. Results: Sixty-eight responses were received on behalf of 74 (of 151) local authorities (49%), across all geographical regions. Our findings suggest a basic typology of delivery, though with considerable variation in who is providing the Checks, where and how, and with continued changes prompted by the Covid-19 pandemic. Support for risk management is highly varied with notable gaps in some areas. Local authorities using a model of delivery that includes community venues tended to have a higher number of services to support behaviour change following the Check, and greater confidence in the accessibility and usage of these services. A minority of local authorities gather data on referrals for Health Check attendees, or on outcomes of referrals. Conclusions: The Covid-19 pandemic has prompted continued changes in delivery, which are likely to influence patient experience and outcomes; these need careful evaluation. The programme’s delivery and commissioners' intentions to follow through risk communication with appropriate support is challenged by the complexity of the commissioning landscape.

ObjectiveTo assess the diagnostic efficacy of metagenomic next generation sequencing (mNGS) for proven invasive pulmonary aspergillosis (IPA).MethodsA total of 190 patients including 53 patients who had been diagnosed with proven IPA were retrospectively analyzed. Using the pathological results of tissue biopsy specimens as gold standard, we ploted the receiver operating characteristic (ROC) curve to determine the optimal cut-off value of mNGS species-specific read number (SSRN) of Aspergillus in bronchoalveolar lavage fluid (BALF)for IPA. Furthermore, we evaluated optimal cut-off value of mNGS SSRN in different populations.ResultsThe optimal cut-off value of Aspergillus mNGS SSRN in BALF for IPA diagnosis was 2.5 for the whole suspected IPA population, and 1 and 4.5 for immunocompromised and diabetic patients, respectively. The accuracy of mNGS was 80.5%, 73.7% and 85.3% for the whole population, immunocompromised and diabetic patients, respectively.ConclusionsThe mNGS in BALF has a high diagnostic efficacy for proven IPA, superioring to Aspergillus culture in sputum and BALF and GM test in blood and BALF. However, the cut-off value of SSRN should be adjusted when in different population.

Published: August 2023

Background: Pregnant women have a higher risk of severe illness and adverse pregnancy outcomes due to a SARS-CoV-2 infection. COVID-19 vaccination can prevent (severe) infection. Observational studies are needed to ascertain safety of COVID-19 vaccination during pregnancy.Aim: Estimate whether COVID-19 vaccination during pregnancy is associated with the risk of preterm labor (PL).Methods: In this prospective cohort study, we included 5,910 pregnant women (mean age: 33.0 ± 3.7 years) who entered the Dutch Pregnancy Drug Register between February 2021 and August 2022. Information on COVID-19 vaccinations, PL, and confounders were self-reported using web-based questionnaires. The hazard ratio (HR) on PL, comparing those who received ≥1 COVID-19 vaccine during any moment of pregnancy to those who did not, was estimated using survival analyses with vaccination as time-varying exposure. Additionally, we estimated the risk of PL after COVID-19 vaccination prior to pregnancy, and after COVID-19 vaccination during trimester 1, 2, or 3 of pregnancy.Findings: A total of 5,227 (88%) participants received ≥1 COVID-19 vaccine between gestational week 2 and 37. We observed no statistically significant association of COVID-19 vaccination during pregnancy (adjusted HR = 0.93, 95%CI = 0.59; 1.45) nor of COVID-19 vaccination prior to pregnancy (adjusted HR = 1.09, 95%CI = 0.70; 1.71) with the risk of PL. Moreover, we observed no association between the risk of PL and COVID-19 vaccination in any trimester of pregnancy.Discussion: We demonstrated that COVID-19 vaccination prior to or during pregnancy is not associated with an increased risk of PL.Conclusion: These results add to the growing evidence supporting safety of COVID-19 vaccination during pregnancy.
