Expansion in whole genome sequencing and subsequent increase in antibiotic resistance targets have paved the way of high throughput qPCR (HT-qPCR) for analyzing hundreds of antimicrobial resistance genes (ARGs) in a single run. A meta-analysis of 51 selected studies is performed to evaluate ARGs abundance trends over the last 7 years. WaferGenTM SmartChip is found to be the most widely used HT-qPCR platform among others for evaluating ARGs. Up till now around 1000 environmental samples (excluding biological replicates) from different parts of the world have been analyzed on HT-qPCR. Calculated detection frequency and normalized ARGs abundance (ARGs/16S rRNA gene) reported in gut microbiome studies have shown a trend of low ARGs as compared to other environmental matrices. Disparities in the HT-qPCR data analysis which are causing difficulties to researchers in precise interpretation of results have been highlighted and a possible way forward for resolving them is also suggested. The potential of other amplification technologies and point of care or field deployable devices for analyzing ARGs have also been discussed in the review. Our review has focused on updated information regarding the role, current status and future perspectives of HT-qPCR in the field of antimicrobial resistance.

Waterborne diseases, such as Hepatitis A and E, are major public health concerns in most of the developing nations, indicating the need for proper outbreak prevention, surveillance, and timely management. This study presents data regarding the prevalence and epidemiological characteristics of hepatitis A and E outbreaks as well as water quality in Kashmir, India, during 2015–2017. Hepatitis outbreaks were initially investigated by rapid response teams, under the Integrated Disease Surveillance Programme. Suspected cases were further evaluated by blood sampling to confrm the disease along with water sampling evaluation. Between 2015 and 2017, 23 disease outbreaks were recorded; among these, four outbreaks occurred in 2015, 12 in 2016, and seven in 2017. Specifcally, 12 of the total outbreaks were concerned with hepatitis A infection, 10 concerned hepatitis E infection, and one involved eight cases of jaundice with neither hepatitis A virus nor hepatitis A virus detected in blood sampling. Overall, during the aforementioned period, 393 cases of hepatitis A or E were detected. Regarding water quality, which was evaluated using the most probable number method for counting coliform, 38 of 50 water samples were found to be unft for human consumption and one source was found to be suspicious. This study of prevalence and epidemiology of hepatitis A and E along with its relationship with water quality and socioeconomic factors, such as poor hygiene and lack of access to safe water, aids towards the implementation of effective preventive sanitary measures and public health actions.

Mumps is a public health problem on a global scale caused by mumps virus, a member of family paramyxoviridae. An effective form of vaccination exists and is incorporated into routine immunization schedules in over 100 countries, usually in the form of the Measles, Mumps and Rubella (MMR) vaccine. This is not the case in India, as mumps is not viewed as a significant enough public health problem by the government to warrant such an intervention. This original research paper discusses about outbreaks of mumps in Kashmir, India and aims to add to the body of literature to support the routine immunization with the mumps vaccine. From July to September 2017, there were 15 outbreaks and 260 cases of mumps recorded in the region by the Integrated Disease Surveillance Programme (IDSP). We conclude that the Indian Government should include the MMR vaccination in the Universal Immunization Programme. This would result in clinical and economic benefits by reducing outbreaks and associated morbidity of mumps, in addition to tackling the recognized morbidity and mortality of rubella and measles. To support the global health security, there is a great need to strengthen surveillance, adhere to the World Health Organization’s International Health Regulations (IHRs), and pay attention to emerging and re-emerging infectious agents, including paramyxovirus group.

Background Antimicrobial resistance (AMR) is an emerging threat to public health worldwide. A significant evidence has suggested that the knowledge and attitude trends among the community, pharmacists and physicians can play a critical role in managing the ever increasing threat of AMR. Methods A cross-sectional survey was performed using three specific self-administered questionnaires for community members, pharmacists/pharmacy owners and physicians on a randomly selected sample population of 473, 424 and 308 respectively. Bivariate and multivariate logistic regression and Pearson chi-square tests were performed during data analysis. Result A response rate of 81.2% ( n  = 385), 37.7% ( n  = 160) and 53.9% ( n  = 166) was achieved for general community, pharmacists/pharmacy owners and physicians respectively. More than half of the community participants (55.6%; n  = 214) possess poor knowledge of AMR. Furthermore, knowledge and attitude of the community participants were also found to be significantly correlated (r 2  = 0.02) with each other. In 90.6% ( n  = 145) of the pharmacies included in the survey, a qualified pharmacist was not present at the time of the operations. Only 36.9% physicians ( n  = 60) knew about the environmental route of dissemination of AMR. Majority of the physicians agreed that AMR is a global problem and also recognize the need for initiating AMR stewardship programs. Conclusion Our study will provide effective assessment and potential insights in designing tri-faceted interventions for rationalizing antibiotics consumption thus controlling the development and dissemination of AMR.

Background Cerebellar abscesses are rare, life-threatening infections often originating from bacterial sources, while metastatic brain lesions from lung adenocarcinoma are relatively common. However, the coexistence of a cerebellar abscess secondary to metastatic lung adenocarcinoma is exceedingly rare and presents unique diagnostic and management challenges. Case Presentation We report a case of a 35 year-old Pakistani female patient with persistent headaches, nausea, and vertigo, who was found to have a large cerebellar mass with features suggestive of metastatic lung adenocarcinoma. Further investigation revealed a concomitant cerebellar abscess. Surgical excision and broad-spectrum antibiotics were initiated, resulting in a favorable outcome. Conclusion This case showcases the rarity and complexity of cerebellar abscesses due to metastatic lung adenocarcinoma. Timely intervention, including surgery and targeted therapy, is crucial for successful management. Further research is needed to enhance treatment strategies.

BackgroundDespite vaccinations are scientifically proven to be safe and effective public controversies limit their application in many countries.AimsAim of this review is to provide an overview of biological effects of vaccination and a picture of the ethical dilemmas about compulsory vaccination.MethodsWe conducted a review on the literature about the subject. Recent news were also included.ResultsVaccines are the best weapon against many infectious diseases. The spread of false beliefs among people have led the government authorities to increase compulsory vaccination in order to embank new outbreaks of preventable infectious diseases.ConclusionEven if compulsory is quite drastic approach it could be the on only way to reach an adequate coverage and protect immunoexpressed subjects.

An estimated 32,000 children develop multidrug-resistant tuberculosis (MDR-TB; Mycobacterium tuberculosis resistant to isoniazid and rifampin) each year. Little is known about the optimal treatment for these children. To inform the pediatric aspects of the revised World Health Organization (WHO) MDR-TB treatment guidelines, we performed a systematic review and individual patient data (IPD) meta-analysis, describing treatment outcomes in children treated for MDR-TB. To identify eligible reports we searched PubMed, LILACS, Embase, The Cochrane Library, PsychINFO, and BioMedCentral databases through 1 October 2014. To identify unpublished data, we reviewed conference abstracts, contacted experts in the field, and requested data through other routes, including at national and international conferences and through organizations working in pediatric MDR-TB. A cohort was eligible for inclusion if it included a minimum of three children (aged <15 years) who were treated for bacteriologically confirmed or clinically diagnosed MDR-TB, and if treatment outcomes were reported. The search yielded 2,772 reports; after review, 33 studies were eligible for inclusion, with IPD provided for 28 of these. All data were from published or unpublished observational cohorts. We analyzed demographic, clinical, and treatment factors as predictors of treatment outcome. In order to obtain adjusted estimates, we used a random-effects multivariable logistic regression (random intercept and random slope, unless specified otherwise) adjusted for the following covariates: age, sex, HIV infection, malnutrition, severe extrapulmonary disease, or the presence of severe disease on chest radiograph. We analyzed data from 975 children from 18 countries; 731 (75%) had bacteriologically confirmed and 244 (25%) had clinically diagnosed MDR-TB. The median age was 7.1 years. Of 910 (93%) children with documented HIV status, 359 (39%) were infected with HIV. When compared to clinically diagnosed patients, children with confirmed MDR-TB were more likely to be older, to be infected with HIV, to be malnourished, and to have severe tuberculosis (TB) on chest radiograph (p < 0.001 for all characteristics). Overall, 764 of 975 (78%) had a successful treatment outcome at the conclusion of therapy: 548/731 (75%) of confirmed and 216/244 (89%) of clinically diagnosed children (absolute difference 14%, 95% confidence interval [CI] 8%-19%, p < 0.001). Treatment was successful in only 56% of children with bacteriologically confirmed TB who were infected with HIV who did not receive any antiretroviral treatment (ART) during MDR-TB therapy, compared to 82% in children infected with HIV who received ART during MDR-TB therapy (absolute difference 26%, 95% CI 5%-48%, p = 0.006). In children with confirmed MDR-TB, the use of second-line injectable agents and high-dose isoniazid (15-20 mg/kg/day) were associated with treatment success (adjusted odds ratio [aOR] 2.9, 95% CI 1.0-8.3, p = 0.041 and aOR 5.9, 95% CI 1.7-20.5, p = 0.007, respectively). These findings for high-dose isoniazid may have been affected by site effect, as the majority of patients came from Cape Town. Limitations of this study include the difficulty of estimating the treatment effects of individual drugs within multidrug regimens, only observational cohort studies were available for inclusion, and treatment decisions were based on the clinician's perception of illness, with resulting potential for bias. This study suggests that children respond favorably to MDR-TB treatment. The low success rate in children infected with HIV who did not receive ART during their MDR-TB treatment highlights the need for ART in these children. Our findings of individual drug effects on treatment outcome should be further evaluated.

North West Pakistan is an area ravaged by conflict and population displacement for over three decades. Recently, drone attacks and military operations have aggravated underlying mental disorders, while access to care is limited. Among patients attending a mental health clinic integrated in district hospital conducted by psychologists; we describe service utilization, patient characteristics, presenting complaints, morbidity patterns, and follow-up details. A retrospective study using routinely collected programme data was conducted from February to December 2012. A total of 1545 consultations were conducted for 928 patients (86% females). There were 71(8%) children and adolescents. An increase was observed from February to July, followed by a decline. 163 new patients (18%) were on psychotropic medication at presentation. The most common morbidity in females (36%) were symptoms of adjustment disorders and acute reactions. Depression and anxiety were common in both genders while post traumatic disorder was frequent in males (21%). Out of the 928 new patients, 639(69%) had a follow up visit planned with their psychologist, but only 220(34%) new patients returned for a follow up visit. In a district hospital, mental health services managed by psychologists were well attended. There is a need to consider widening the current package of care to cater to the diversity of mental health disorders, gender difference, children and adolescents. Standardized diagnostic and monitoring tools would also need to be adapted accordingly and to assess patient progress. Innovative approaches to tackle the problem of the low return rate are needed.

The current study was conducted to evaluate maize hybrids for their high temperature tolerance ability based on their performance as assessed through different high temperature stress indices. Nine maize hybrids were screened under optimal and high temperature stress conditions (late sowing) for three consecutive spring seasons (Spring 2017-18, 2018-19 and 2019-20), laid out under split-split-plot design under RCBD. Results reveled significant differences among stress indices for all three seasons and both conditions. Correlation analysis indicated that some high temperature stress indices i.e., STI, MP, GMP and HARM had a strong positive correlation with kernel yield under normal (Yp) and high temperature stress conditions (Ys). Biplot analysis further unveiled that two local maize hybrids i.e., YH-5507 and YH-5427 were the most productive, stable and heat tolerant while YH-5532, P-1543 and NK-8711 showed poor performance under high temperature stress conditions as compared to normal sowing. High temperature stress indices could be efficiently used to screen heat tolerant genotypes.

Antiviral drugs are a class of medicines particularly used for the treatment of viral infections. Drugs that combat viral infections are called antiviral drugs. Viruses are among the major pathogenic agents that cause number of serious diseases in humans, animals and plants. Viruses cause many diseases in humans, from self resolving diseases to acute fatal diseases. Developing strategies for the antiviral drugs are focused on two different approaches: Targeting the viruses themselves or the host cell factors. Antiviral drugs that directly target the viruses include the inhibitors of virus attachment, inhibitors of virus entry, uncoating inhibitors, polymerase inhibitors, protease inhibitors, inhibitors of nucleoside and nucleotide reverse transcriptase and the inhibitors of integrase. The inhibitors of protease (ritonavir, atazanavir and darunavir), viral DNA polymerase (acyclovir, tenofovir, valganciclovir and valacyclovir) and of integrase (raltegravir) are listed among the Top 200 Drugs by sales during 2010s. Still no effective antiviral drugs are available for many viral infections. Though, there are a couple of drugs for herpesviruses, many for influenza and some new antiviral drugs for treating hepatitis C infection and HIV. Action mechanism of antiviral drugs consists of its transformation to triphosphate following the viral DNA synthesis inhibition. An analysis of the action mechanism of known antiviral drugs concluded that they can increase the cell’s resistance to a virus (interferons), suppress the virus adsorption in the cell or its diffusion into the cell and its deproteinisation process in the cell (amantadine) along with antimetabolites that causes the inhibition of nucleic acids synthesis. This review will address currently used antiviral drugs, mechanism of action and antiviral agents reported against COVID-19.
