Recurrent concussions increase risk for persistent post-concussion symptoms, and may lead to chronic neurocognitive deficits. Little is known about the molecular pathways that contribute to persistent concussion symptoms. We hypothesized that salivary measurement of microribonucleic acids (miRNAs), a class of epitranscriptional molecules implicated in concussion pathophysiology, would provide insights about the molecular cascade resulting from recurrent concussions. This hypothesis was tested in a case-control study involving 13 former professional football athletes with a history of recurrent concussion, and 18 age/sex-matched peers. Molecules of interest were further validated in a cross-sectional study of 310 younger individuals with a history of no concussion (n = 230), a single concussion (n = 56), or recurrent concussions (n = 24). There was no difference in neurocognitive performance between the former professional athletes and their peers, or among younger individuals with varying concussion exposures. However, younger individuals without prior concussion outperformed peers with prior concussion on three balance assessments. Twenty salivary miRNAs differed (adj. p < 0.05) between former professional athletes and their peers. Two of these (miR-28-3p and miR-339-3p) demonstrated relationships (p < 0.05) with the number of prior concussions reported by younger individuals. miR-28-3p and miR-339-5p may play a role in the pathophysiologic mechanism involved in cumulative concussion effects.

Abstract: Smokers can be found in almost all groups of people worldwide since cigarettes can be obtained easily anywhere and have been addicted by adult smokers. Leukoedema is one of the lesions in oral cavity that most often appears in smokers. This study was aimed to obtain the description of leukoedema cases among smokers. This was a literature review study. This study used previous studies or reports related to leukoedema in smokers. There were 13 literatures in this study consisting of 9 cross-sectional studies, 3 cohort studies, and 1 case control study. The results showed that leukoedema lesions were more common in smokers than in those who consumed tobacco. Leukoedema was closely related to the duration of smoking and the frequency of smoking in a day. Leukoedema was also more common in men than in women, and was often found bilaterally on the buccal mucosa. In conclusion, leucoedema was most common in cigarette smokers and was related to duration of smoking, frequency of smoking per day, and sex. It was often found bilaterally on the buccal mucosa.Keywords: smokers, leukoedema Abstrak: Perokok ditemukan pada hampir semua kelompok masyarakat di dunia.

In health sciences, the epidemiological method can be divided into descriptive and analytical epidemiology and the latter being divided into observational (cross-sectional study, case-control study and cohort study) and experimental studies. Cohort studies may be retrospective or prospective, and both assume that the researcher will follow a population over time to seek a possible association between exposure (s) and outcome(s). These types of studies have as advantages the possibility of measuring several exposure factors and outcomes, both primary and secondary, for both relatively frequent outcomes and rare exposure factors. However, they are often long and therefore expensive studies. They have as main biases those of selection, memory and information. These are studies that may point to statistical associations between exposure and outcome that need other models to prove the casualty of these associations.

In 2019, a novel severe acute respiratory syndrome (SARS-CoV-2 (COVID-19)) caused a global pandemic. There was an urgent need to develop a vaccine against COVID-19 to reduce its spread and economic burden. The main objective of this study was to understand the attitudes and concerns of healthcare workers (HCWs) towards the upcoming COVID-19 vaccine, whether their decision was influenced by their history of taking the seasonal influenza vaccine, and factors that influence the acceptance of the upcoming COVID-19 vaccine. This was a cross-sectional study conducted in Riyadh, Saudi Arabia. We selected and surveyed 356 HCWs via an electronic self-administered questionnaire. A total of 61.16% of HCWs were willing to receive the COVID-19 vaccine, and 55.9% of them had received the seasonal influenza vaccine in the preceding year (2019–2020). The strongest predictors for taking the COVID-19 vaccine were the HCWs’ belief that the COVID-19 vaccine would be safe, needed even for healthy people, that all HCWs should be vaccinated against COVID-19, and that HCWs will have time to take the vaccine. Being female, being middle aged, having <5 years of work experience, having no fear of injections, and being a non-smoker were predictive factors for taking the upcoming COVID-19 vaccine. No associations were found between the intention to take the COVID-19 vaccine and a history of taking the seasonal influenza vaccine.

Abstract Background Prisons are considered as major reservoirs for tuberculosis. Preventive therapy for latent TB infection (LTBI) is an adjunctive strategy to control TB. However, LTBI data in Thai prisoners is limited. This study assessed the prevalence of LTBI and feasibility of isoniazid preventive therapy (IPT). Methods A cross-sectional study was conducted among prisoners in Klong Prem Central Prison, Bangkok. Participants were screened for active TB by questionnaire and chest X-ray. LTBI was evaluated by Tuberculin skin test (TST) and QuantiFERON-TB Gold Plus (QFTP) among subgroup. Participants with positive TST or QFTP were considered to have LTBI. Participants with LTBI were offered IPT. Results From August 2018–November 2019, 1002 participants were analyzed. All participants were male with a median age of 38 (IQR 32–50) years. LTBI identified by either TST/QFTP was present in 466 (46.5%) participants. TST was positive in 359 (36%) participants. In the subgroup of 294 participants who had both TST and QFTP results, 181/294 (61.6%) tested positive by QFTP. Agreement between TST and QFTP was 55.1% (Kappa = 0.17). The risk factors associated with LTBI were previous incarceration (aOR 1.53, 95%CI, 1.16–2.01, p = 0.002), history of prior active TB (aOR 3.02, 95%CI, 1.74–5.24, p < 0.001) and duration of incarceration ≥10 years (aOR 1.86, 95%CI, 1.24–2.79, p = 0.003). Majority of LTBI participants (82%) agreed to take IPT. Three hundred and 56 (93%) participants completed treatment whereas 27 (7%) participants discontinued IPT due to the side effects of INH. Conclusion This is the first study to evaluate the prevalence of LTBI and feasibility of IPT among Thai prisoners. LTBI prevalence in male prisoners in Thailand is high. LTBI screening and treatment should be implemented together with other preventive components.

Imported malaria has increased in Colombia since 2015 and has been attributed to migrants coming from Venezuela. We present a series of malaria cases, nested in a retrospective cross-sectional study between 2017 and 2018, aimed at calculating the prevalence of medical diseases among immigrants in a University Hospital in Colombia. Among 154 immigrants admitted for medical causes between 2017 and 2018, 8 were diagnosed with malaria, all due to Plasmodium vivax. Of these, seven had uncomplicated malaria, five had a previous history of malaria, one was critically ill, but none died. We highlight that, similar to other case series of imported malaria, Latin American migrants were young, with similar clinical profiles, having a low proportion of severe cases, and P. vivax was the most frequent cause.

This cross-sectional study compared attachment characteristics among women victimized by intimate partner violence (IPV) in no, one, and multiple relationships ( N = 154). Results indicated that compared with the nonvictimized, victimized women had increased likelihood of higher attachment avoidance. Compared with women victimized in one relationship, women victimized in multiple relationships had higher likelihood of higher attachment anxiety scores. Adjusting for childhood adversities, childhood sexual abuse was an independent risk factor for IPV. Childhood emotional abuse mediated the association between attachment anxiety and IPV victimization in multiple relationships in particular. Attachment theory appeared useful for better understanding women’s vulnerability for multiple violent relationships.

Abstract Background The risk of hepatitis B virus infection among medical waste handlers who undergo collection, transportation, and disposal of medical wastes in the health institutions is higher due to frequent exposure to contaminated blood and other body fluids. There is limited evidence on the seroprevalence of hepatitis B among medical waste handlers in eastern Ethiopia. The study was aimed at studying the seroprevalence of Hepatitis B Virus and associated risk factors among medical waste collectors at health facilities of eastern Ethiopia. Methods A facility-based cross-sectional study was conducted among randomly selected medical waste collectors from public health facilities in eastern Ethiopia from March to June 2018. A pre-tested and well-structured questionnaire was used to collect data on socio-demographic characteristics and hepatitis B infection risk factors. A2.5ml venous blood was also collected, centrifuged and the serum was analyzed for hepatitis B surface antigen using the instant hepatitis B surface antigen kit. Descriptive summary measures were done. Chi-square and Fisher exact tests were used to assess the risk of association. Multivariate logistic regression was conducted with 95% CI and all value at P-value < 0.05 was declared statistically significant. Results From a total of 260 (97.38%) medical waste collectors participated, HBV was detected in 53 (20.4%) of the participants [95%CI; 15.8, 25.6]. No significant differences were observed in the detection rates of HBV with respect to socio-demographic characteristics. In both bivariate and multivariable logistic regression analysis, being unvaccinated (AOR = 6.35; 95%CI = [2.53–15.96], P = 0.001), history of blood transfusion (receiving) (AOR; 3.54; 95%CI; [1.02–12.24], P = 0.046), history of tattooing (AOR = 2.86; 95%CI = [1.12–7.27], p = 0.03), and history of multiple sexual partner (AOR = 10.28; 95%CI = [4.16–25.38], P = 0.001) remained statistically significantly associated with HBsAg positivity. Conclusion This cross-sectional study identified that HBV infection is high among medical waste collectors in eastern Ethiopia. Immunization and on job health promotion and disease prevention measures should be considered in order to control the risk of HBV infection among medical waste collectors in eastern Ethiopia.
