Bacterial meningitis is a global public health concern, with several responsible etiologic agents that vary by age group and geographical area. The aim of this systematic review and meta-analysis was to assess the etiology of bacterial meningitis in different age groups across global regions. PubMed and EMBASE were systematically searched for English language studies on bacterial meningitis, limited to articles published in the last five years. The methodological quality of the studies was assessed using a customized scoring system. Meta-analyses were conducted to determine the frequency (percentages) of seven bacterial types known to cause meningitis: Escherichia coli, Haemophilus influenzae, Neisseria meningitidis, Streptococcus pneumoniae, group B Streptococcus agalactiae, Staphylococcus aureus, and Listeria monocytogenes, with results being stratified by six geographical regions as determined by the World Health Organization, and seven age groups.Of the 3227 studies retrieved, 56 were eligible for the final analysis. In all age groups, S. pneumoniae and N. meningitidis were the predominant pathogens in all regions, accounting for 25.1–41.2% and 9.1–36.2% of bacterial meningitis cases, respectively. S. pneumoniae infection was the most common cause of bacterial meningitis in the ‘all children’ group, ranging from 22.5% (Europe) to 41.1% (Africa), and in all adults ranging from 9.6% (Western Pacific) to 75.2% (Africa). E. coli and S. pneumoniae were the most common pathogens that caused bacterial meningitis in neonates in Africa (17.7% and 20.4%, respectively). N. meningitidis was the most common in children aged ±1–5 years in Europe (47.0%). Due to paucity of data, meta-analyses could not be performed in all age groups for all regions.A clear difference in the weighted frequency of bacterial meningitis cases caused by the different etiological agents was observed between age groups and between geographic regions. These findings may facilitate bacterial meningitis prevention and treatment strategies.

Herpes zoster (HZ) is associated with substantial morbidity. It is caused by reactivation of the latent varicella zoster virus (VZV) following decline in cell-mediated immunity, which is commonly age-related, but also occurs in individuals with immunosuppressive diseases and/ or treatment. Since coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, has been associated with T cell immune dysfunction and there have been reports of HZ in COVID-19 patients, we have performed a review of available literature on whether COVID-19 could trigger HZ. We identified 27 cases of HZ following COVID-19, which most frequently occurred within 1-2 weeks of COVID-19, and the majority of cases had typical presentation. Atypical presentations of HZ were noted especially in patients with lymphopenia. It has been hypothesized that VZV reactivation occurs as a consequence of T cell dysfunction (including lymphopenia and lymphocyte exhaustion) in COVID-19 patients. Based on current evidence, which is limited to case reports and case series, it is not possible to determine whether COVID-19 increases the risk of HZ. Practitioners should be aware of the possible increased risk of HZ during the pandemic period and consider timely therapeutic and preventive measures against it.

Introduction Several chronic underlying conditions (UCs) are known to be risk factors for developing herpes zoster (HZ) and to increase the severity of HZ and its risk of recurrence. The aim of this study was to investigate the incidence and recurrence of HZ in adult patients with one or multiple UCs. Methods A retrospective cohort study based on claims data representing 13% of the statutory health insurance population from 2007 to 2018 in Germany was performed. Patients aged ≥ 18 years were included when at least one of the following UCs was diagnosed: asthma, chronic heart failure, chronic obstructive pulmonary disease (COPD), coronary heart disease (CHD), depression, diabetes mellitus type 1 or 2, and rheumatoid arthritis (RA). Exact matching was used to account for differences in the distribution of age and sex between the case and matched control cohorts. Multi-morbidity was considered in sensitivity analyses by analyzing patients with only one UC. Results Patients with asthma, CHD, COPD, depression, and RA had, on average, a 30% increased risk of developing acute HZ compared to patients without any UC. RA was found to have the highest odds ratio among these conditions, varying from 1.37 to 1.57 for all age groups. Patients with depression also showed a high risk of developing HZ. Analysis of recurrence indicated that patients with at least one UC in the age groups 18–49 years and 50–59 years had the highest risk for a recurrent HZ. After experiencing a first recurrence, patients, regardless of age group, had a two- to threefold higher risk for a second recurrence. Conclusion This study of representative claims data shows a higher HZ incidence and recurrence frequency in patients with UCs. These results provide relevant information for national health care guidelines and disease management programs.

Background Case reports have described herpes zoster (HZ) in patients with COVID-19. However, this constitutes low-quality evidence for an association. We therefore performed a retrospective cohort study to assess the risk of developing HZ following a COVID-19 diagnosis. Methods We compared the HZ incidence in ≥50-year-olds diagnosed with COVID-19 versus those never diagnosed with COVID-19. We used data from the US MarketScan Commercial Claims and Encounters and Medicare Supplemental (3/2020-2/2021) and Optum Clinformatics Data Mart (3-12/2020) databases. Individuals with COVID-19 were exact-matched 1:4 to those without COVID-19 by age, sex, presence of HZ risk factors and health-care cost level. Adjusted incidence rate ratios (aIRRs) were estimated by Poisson regression. Results 394,677 individuals ≥50 years old with COVID-19 were matched with 1,577,346 individuals without COVID-19. Mean follow-up time after COVID-19 diagnosis and baseline characteristics were balanced between cohorts. Individuals diagnosed with COVID-19 had a 15% higher HZ risk than those without COVID-19 (aIRR: 1.15, 95% confidence interval [CI]: 1.07-1.24; p<0.001). The increased HZ risk was more pronounced (21%) following COVID-19 hospitalization (aIRR: 1.21, 95%CI: 1.03-1.41; p=0.02). Conclusions We found that COVID-19 diagnosis in ≥50-year-olds was associated with a significantly increased risk of developing HZ, highlighting the relevance of maintaining HZ vaccination.

Background: People with disabilities are more vulnerable than general population to a range of problem including fatigue, depression, and social isolation and have more limited access to health care. It is among the poorest communities that poverty breeds disablement and disablement breeds poverty, a vicious cycle that the poor can least affords. Most of the disabilities can be prevented if proper preventive and rehabilitative measures of impairments are undertaken. Aims & Objectives: To study awareness and utilization of rehabilitation services among disabled. Materials and Methods: Multistage sampling technique was used in this study. For determining target sample size, population proportionate sampling was used. All the family members who are regular resident of the village were considered for the study. Disability criteria of National Sample Survey (NSS) 2002, was used. Data was analyzed for rates and proportions. Results: Prevalence of physical disabilities was 19.46 per 1000. 64.71% disabled were unaware about the availability of the rehabilitation services and unawareness was main reason for not availing rehabilitation services. Amongst physically disabled, 65.85% discontinued the treatment and 19.51% had not taken treatment at all. Conclusion: There is lack of awareness and utilization regarding the available rehabilitation services in the country. Physical disability was found to be higher among illiterates and community having low and medium standard of living.
