RESUMO
Millions of people worldwide are currently afflicted with neurologic conditions like a seizure, depression, stress, Alzheimer's disease, Parkinson's disease, and Huntington's disease. However, the precise etiopathology of these diseases is still unknown. Substantial studies are being conducted to discover more treatments against these disorders because many patients do not experience the therapeutic benefits that would be expected from using existing pharmaceutical strategies. Herbal medicines which have been used in traditional medicine for millennia to treat various neurological problems are also being investigated and scientifically assessed. Punicalagin is a known polyphenol that has significant antioxidant, anti-inflammatory, anti-viral, anti-proliferative, and anti-cancer properties. Around the world, traditional use of herbal drugs is gaining wider acceptance as a part of complementary and alternative medicine. The scientific community should pay attention to these many neuroprotective pharmacodynamic activities of Punicalagin to create effective pharmacotherapeutic plans, as evidenced by mounting data in pre-clinical research investigations. The current review describes the recent studies on the pharmacological effects of Punicalagin in a variety of neurological illnesses and paves the way for further study in this field.
RESUMO
Background: A serious problem in cirrhosis is acute renal injury. The study aimed to examine the urinary neutrophil gelatinase-associated lipocalin (uNGAL) as a diagnostic and prognostic marker of acute kidney injury (AKI) in cirrhotic patients. Methods: A prospective study was carried out over a period of 1 year. A total of 490 patients suffering from cirrhosis who visited an indoor hospital were screened, and after the exclusion, a total of 90 subjects admitted to the medicine intensive care unit (MICU) fulfilling inclusion criteria were enrolled. Those having a history of renal diseases, on nephrotoxic drugs, in septic shock, peritonitis, UTI, and no urine output were excluded. On admission, for the estimation of uNGAL, urinary levels of sodium, creatinine, fresh urine samples were obtained, and blood samples were taken for serum creatinine estimation. Results: Out of 90 patients, 33.3% did not develop AKI, and 66.7% developed AKI. Urinary neutrophil gelatinase-associated lipocalin levels were six times higher in patients with acute tubular necrosis (259.08 ± 118.41 ng/mL) and three times higher in Hepatorenal syndrome (HRS)-AKI (124.97 ± 16.38) as compared with patients with normal kidney function (39.76 + 5.7). Those who died had a higher uNGAL (171.6 ng/mL) in comparison to those who survived (133.7 ng/mL). At a cutoff value of ≥114.9 (ng/mL), urinary NGAL represents a sensitivity of 86.92% and specificity of 100% to diagnose AKI and AUC 0.966 (95% CI: 0.919-0.990) in cirrhotic patients. Conclusion: Urinary NGAL is good for diagnosing AKI and is a marker to distinguish the types of AKI in liver cirrhosis. How to cite this article: Patel ML, Shyam R, Chaudhary A, Sachan R, Ali W.

RESUMO
Psychiatric disorders are frequent among people with epilepsy but often under-recognized. The diagnosis and treatment of these disorders in low- and low-middle-income countries (LMICs) are challenging. METHODS: This cross-sectional survey included people recruited during a community epilepsy screening program involving 59,509 individuals from poor communities in Ludhiana in Northwest India. Adults (age ≥18 years) with confirmed epilepsy on antiseizure medications were screened for depression and anxiety using the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) and Generalized Anxiety Disorder-7 (GAD-7) twice over two years of follow-up. They were later interviewed for symptoms using the Brief Psychiatric Rating Scale, which was then confirmed by assessments by an experienced psychiatrist. RESULTS: Of the 240 people with confirmed epilepsy, 167 (70%) were adults, of whom, 116 (70%) eventually participated in the study. The NDDI-E with a cut-off of 15 identified depression in 14 (12%) of 116 people after one year of follow-up and 17 (15%) at two years. The GAD-7 using a cut-off of 6 identified 22 (19%) at one year and 32 (28%) with anxiety at two years. The area under the curves for NDDI-E was estimated as 0.62 (95%CI, 0.51-0.73; SE: 0.06; p = 0.04) and for GAD-7 as 0.62 (95%CI, 0.46-0.78; SE: 0.08; p = 0.12). Brief Psychiatric Rating Scale identified 63 (54%) people with psychiatric symptoms, for whom, a psychiatric diagnosis was confirmed in 60 (52%). A psychiatric diagnosis was associated with education below high school [Odds Ratio (OR): 2.59, 95%CI, 1.12-5.1; p = 0.03], later age of seizure onset (OR, 1.05, 95%CI: 1.0-1.10; p = 0.04), seizure frequency of at least one/year at enrolment (OR, 2.36, 95%CI: 1.0-5.58; p = 0.05) and the use of clobazam (OR, 5.09, 95%CI, 1.40-18.42; p = 0.01). CONCLUSION: Depression and anxiety are common in people with epilepsy. Our findings underscore the low yields of screening instruments, NDDI-E and GAD-7, and comparatively better professionally-administered diagnostic assessments in resource-limited settings in LMICs. Moreover, previously established cut-offs do not apply to the community studied.

BACKGROUND AND AIMS: The burden of healthcare-associated infections (HAIs) is very high and compliance with infection control practices is poor in low and middle-income countries (LMICs). Hand hygiene (HH) being the most important measure to prevent HAIs, the present study was conducted to assess the gap in knowledge, perceptions, and practices of healthcare providers (HCPs) regarding HH and also to know the barriers in adherence to HH practices. MATERIAL AND METHODS: This questionnaire-based cross-sectional study was carried out among 400 HCPs for 1 year. HH practices of HCPs were observed by a trained investigator followed by filling of the preformed proforma by HCPs. The quantitative data were analyzed using Epi info (Version 7) statistical software while qualitative analysis was done to generate themes. RESULTS: The compliance to HH was higher among nurses (78.3%) than consultants (49.5%) and residents (39.1%). Compliance was more in ICUs (71.4%) than wards (58.3%). Knowledge about HH was found to be 73.8% among consultants and 71.6% among residents, whereas HH opportunities availed by them were only 49.5% and 39.1%, respectively revealing a knowledge-practice gap. The main barriers to adherence to HH as perceived by HCPs were lack of awareness despite adequate knowledge, time constraints, heavy workload, and so on. CONCLUSIONS: In our study, we found that despite adequate knowledge, consultants and residents showed lower compliance with HH practices as compared to nurses. Increasing awareness regarding HH guidelines through frequent sensitization sessions decreased workload, and strict surveillance may help in bridging the knowledge-practice gap.

BACKGROUND: Peer-assisted learning (PAL) is a teaching-learning method in which students act as peer teachers and help other students to learn while also themselves learning by teaching. PAL through modified interest building activities (MIBAs) is seldom tried in teaching pathology in medical colleges. This study aimed to evaluate the usefulness of peer teaching using MIBA, obtain feedback from students, and compare different activities with each other and with traditional teaching-learning methods. METHODS: An interventional pilot study was conducted in 2 months on the 2nd MBBS undergraduates learning pathology at a medical college in North India. Students acted as peer teachers and performed different MIBAs including role plays, demonstration of pathogenesis through props, student-led seminars such as PowerPoint teaching, blackboard teaching, multiple choice question seminars, case-based learning (CBL) exercises, and quizzes before teaching sessions. Feedback was obtained through structured questionnaires on a 5-point Likert scale. Paired t-test was used to compare traditional teaching with MIBAs, and Friedman test was used to compare among different MIBAs. RESULTS: Students found ease of understanding and the interaction and involvement of students as the most important benefits of PAL. MIBAs increased voluntary participation, coordination, teamwork, shared responsibility, and group dynamics among students. Quiz sessions followed by PowerPoint seminars and prop demonstrations received highest mean scores from students on most of the parameters. Quizzes, blackboard teaching, prop activities, and CBL helped students understand topics better and generated interest. Learners advocated for making MIBAs and PAL compulsory for future students. DISCUSSION: PAL complemented by MIBAs may be adopted to make teaching-learning more interesting and effective through the active involvement and participation of students.

In response to the escalating issue of antibiotic-resistant bacteria adhering to and thriving on medical equipment, scientists are pioneering innovative "intelligent" materials and coatings. These advancements entail the targeted release of antimicrobial substances, specifically activated when bacteria are detected. The next section discusses three revolutionary substances: hydrogels, nanoparticles, and thin films. Furthermore, intelligent antibacterial materials are divided into 2 groups based on the triggering source: those that react to biological stimuli and those that react to non-biological ones, like temperature and electric cues associated with bacterial presence, such as pH shifts or bacterial enzyme discharge. Moreover, because of their simple construction technique, outstanding biocompatibility, and robust antibacterial characteristics derived from polyphenols and metal ions, metallic-polyphenolic nanoparticles (MPNs) have obtained substantial interest in tackling antimicrobial infections. This article presents an introduction to several MPN-centered biomaterials (like nanoparticles, coatings, capsules, and hydrogels) and highlights the latest advancements in research in its applications for addressing microbial threats in the field of biomedicine. Furthermore, the usage of smart materials is classified based on their application domains, encompassing medical implants, waste reduction, and nano-engineered systems.

A comprehensive literature search was conducted to gather relevant information from various biomedical databases. The chemical composition, mechanism of action, and therapeutic activities of Aloe vera were analyzed. Aloe vera contains numerous active components such as vitamins, enzymes, minerals, sugars, lignin, saponins, and anthraquinones. Its mechanisms of action involve collagen synthesis, anti-inflammatory effects, immune modulation, laxative properties, and antiviral activity. Aloe vera has demonstrated potential therapeutic benefits in wound healing, diabetes management, liver and kidney protection, and glycemic control. However, it is essential to consider potential side effects, such as skin irritation and allergic reactions. This review provides evidence-based information to improve patient safety and promote informed decisions regarding the use of Aloe vera as a therapeutic agent.
RESUMO
Context: Worldwide malnutrition is identified as a major health and nutrition problem. Undernutrition contributes to an estimated 45% of child deaths globally. The prevalence of underweight among children in India is among the highest in the world. Our children also bear a tremendous double burden of malnutrition. Aims: To find out the prevalence and determinants of malnutrition among six months to three-year-old children in the rural community of Northern India. Settings and Design: A community-based cross-sectional study conducted among children aged six months to three years in a rural area of Ludhiana district, Methods and Material: A total of 662 children in the age group of six months to three years from a population of 30,000 were identified and included in the study. All the relevant information regarding these children was collected from family folders. Socioeconomic status was assessed using the modified Udai Pareek scale (MUP). Statistical analysis used: The data collected was entered in MS Excel and was analyzed using SPSS version 26 and WHO Anthro Survey Analyzer. Results: Out of 662 children, 16% were underweight. Almost 50% of the children in the two-three years category were underweight. The prevalence of stunting in the study population was 20.7% and that of overweight was 4.8%. The prevalence of underweight was higher in children of low socioeconomic status than in children from upper socioeconomic status (P = 0.000). There was a significant association between birth order and increasing cases of underweight (P = 0.000). Conclusions: The causes of malnutrition in children are complex and involve multiple factors. There is a need for vigorous monitoring for early detection of malnutrition for children aged two-three years. The improvement of maternal education will improve the nutritional status of the child.
RESUMO
Pediatric brain tumors are the primary cause of death in children with cancer. Diffuse midline glioma (DMG) and diffuse intrinsic pontine glioma (DIPG) are frequently unresectable due to their difficult access location, and 5-year survival remains less than 20%. Despite significant advances in tumor biology and genetics, treatment options remain limited and ineffective. Immunotherapy using T cells with a chimeric antigen receptor (CAR) that has been genetically engineered is quickly emerging as a new treatment option for these patients. High levels of expression were detected for both disialoganglioside (GD2) and B7-H3 in pediatric DMG/DIPG. Numerous studies have been conducted in recent years employing various generations of GD2-CAR T cells. The two most prevalent adverse effects found with this therapy are cytokine release syndrome, which varies in severity from mild constitutional symptoms to a high-grade disease associated with potentially fatal multi-organ failure, and neurotoxicity, known as CAR T-cell-related encephalopathy syndrome. During the acute phase of anticancer action, peri-tumoral neuro-inflammation might cause deadly hydrocephalus. The initial results of clinical trials show that the outcomes are not highly encouraging as B cell malignancies and myelomas. In vivo research on CAR T-cell therapy for DIPG has yielded encouraging results, but in human trials, the early results have shown potentially fatal side effects and very modest, but fleeting improvements. Solid tumors present a hindrance to CAR T-cell therapy because of the antigenic dilemma and the strong immune-suppressing tumor microenvironment.

BACKGROUND: Vaccination is among the most important public health tools for preventing the harm caused by communicable diseases. This was particularly true in the case of COVID-19 vaccination during the COVID-19 pandemic. However, no vaccine is 100% effective, and all carry the risk of breakthrough infection in vaccinated individuals. METHODOLOGY: This longitudinal observational study was done on COVID-19-vaccinated individuals at a vaccination site in a tertiary care hospital. The study participants were categorized into the general community, frontline workers, and healthcare workers and were followed up during the study period from June 2021 to May 2022 post-vaccination. They were interviewed by telephone regarding adverse effects and breakthrough infections post-vaccination during the second and third wave of the COVID-19 pandemic in India. Incidence of breakthrough infection was calculated in all three categories after they received their first, second, and booster doses of vaccination. RESULTS: Fever was the most common adverse effect among all the categories of participants after the first and second doses. Incidence of breakthrough infection after the second dose of vaccination among frontline workers (RR: 5.7, 95% CI: 0.7-44.2) and healthcare workers (RR: 18.9, 95% CI: 2.6-138.6) was observed to be higher compared to the general community, but no such difference was observed among the three categories after the first dose of vaccination. CONCLUSIONS: The incidence of breakthrough infection was found to be the highest in healthcare workers, followed by frontline workers compared to the general community, justifying their work profile and the risk associated with it.
RESUMO
BACKGROUND: Understanding the cognitive and behavioral aspects of Alzheimer's disease- related dementia is surely a sturdy task to deal with. In recent years, a broad search for novel anti-Alzheimer agents has been continuously conducted. The malfunctioning of various neurotransmitter systems and the accumulation of abnormal proteins in the brain are the two key characteristics of this disorder. This is supported by a growing amount of evidence. Some Pharmacophoric groups/combinations exhibit potential neuroprotective activity. METHODS: This study aims to compile the most recent and interesting target/target combinations/ pharmacophoric combinations to cure Alzheimer's disease. We concentrated our efforts to find the ability of certain pharmacophoric elements to interfere with various enzymatic and/or receptor systems or to work as neuroprotective agents. These pharmacophoric elements may be proved to be promising leads for future multi-target anti-Alzheimer drug discovery programs. RESULTS: Anticholinesterase drugs were mentioned as the best treatment thus far. Additionally, impairments in the serotonergic, GABAergic, noradrenergic, dopaminergic, and glutaminergic and a few other pathways have all been linked to memory, speech, behavioral and other alterations in Alzheimer's disease. CONCLUSION: This includes the study of workable pharmacophoric groups/combinations, receptors/ enzymatic systems and related hypotheses to find the promising therapeutic lead compounds which could work as future anti-Alzheimer drugs. We discuss future work that would improve our understanding of this Disease.

In the current portfolio, there is a lot of interest in the 7-azaindole building block for drug discovery. The creation of synthetic, sophisticated methods for the modification of 7-azaindoles is a promising area of research. This review covers the structure-activity relationship of 7-azaindole analogs, which have been shown to be effective anticancer agents in the literature of the past two decades. Positions 1, 3 and 5 of the 7-azaindole ring are the most active sites. Disubstitution is used for the synthesis of a new analog of the 7-azaindole moiety. All positions are used to create novel molecules that are effective anticancer agents. The alkyl, aryl carboxamide group and heterocyclic ring are the most successful types of substitution.

Aim: The aim of this study was to evaluate the factors affecting adherence to antidiabetic medication among diabetic patients in India. Setting and Design: A qualitative study was conducted among 40 diabetic patients aged >30 years, on treatment for more than a year without any complications in the Urban Health Centre of Dayanand Medical College and Hospital, Ludhiana, Punjab, India. Materials and Methods: A semistructured questionnaire was harnessed to congregate data by interviewing the patients for 30-40 min in person. The interviews were recorded in the form of audios by acquiring informed consent and transcribed verbatim. The factors were then divided into barriers and enablers which were further subdivided into themes and subthemes as a result of which four major themes were built including individual, social, organizational, and community levels. These major themes were further categorized into several subthemes to assess the nonadherence to antidiabetic medications. Results: The results of the interviews depicted that the lack of knowledge, financial problems, familial issues, misconceptions regarding the disease, and side effects of taking medications daily were the major altruist for nonadherence, whereas on the other hand, positive perception about the disease, family support, and getting medications on affordable prices by some health-care institutes played an important role in enabling medication adherence as about 50% patients were adherent to the medications. Moreover, various interventions were used to escort the patients regarding medication compliance and blood glucose level monitoring such as lifestyle modifications (diet and exercise), use of reminders for medication intake on time, encouraging them to visit health-care centers, or hospitals on time for regular check-ups and by educating them regarding the long-term effects of diabetes and its prevention.
RESUMO
PURPOSE: To assess the association between epilepsy and exposure to the parasites, Toxocara canis and Taenia solium in a slum-community in India. METHODS: A door-to-door survey to determine the prevalence of epilepsy was carried out by trained field workers. For every case, one age- and gender-matched control was selected from the same community. Serologic evaluation was carried out to detect antibodies against T. canis and T. solium. KEY FINDINGS: The crude prevalence of active epilepsy was 7.2 per 1,000. We enrolled 114 people with active epilepsy and 114 controls. The prevalence of antibodies to T. canis was similar in people with active epilepsy (4.7%; 5 of 106 people) and in controls (5.7%; 6 of 106 people). The prevalence of antibodies to T. solium was 25.5% (27 of 106) in people with active epilepsy, significantly higher than in controls (12.3%; 13 of 106 cases; p = 0.02). Adjusted conditional (fixed-effects) logistic regression estimated an odds ratio of 2.8 (95% confidence interval 1.2-6.8) for detection of T. solium antibodies. Nineteen people with active epilepsy demonstrated evidence of neurocysticercosis (NCC) on magnetic resonance imaging (MRI), including 7 (36.5%) with solitary cysticercus granuloma. SIGNIFICANCE: Our findings do not support an association between epilepsy and exposure to T. canis in the community studied. A significant association between T. solium exposure and epilepsy was observed. Of those with active epilepsy and evidence of NCC on MRI, a large proportion demonstrated solitary cysticercus granuloma.

Chromenes are an important class of oxygen-containing heterocyclic compounds with intriguing biological activity, a simple structure with mild adverse effects. Chromenes are abundantly found in nature in the form of alkaloids, tocopherols, flavone, and anthocyanins. The Chromene nucleus is an important moiety for the discovery of new drug candidates. Chromene derivatives have shown various pharmacological activities like antiviral, anticancer, anti-inflammatory, antitumour, antimicrobial, antiproliferative, anticholinesterase, EPR-1 (Effector cell Protease Receptor-1) antagonist and MAO (Mono-Amine Oxidase) inhibitors. In SAR (Structure Activity Relationship) studies with chromene nucleus, it was found that 4-aryl moiety, 3-cyano group, and 2-amino group are essential for the cytotoxic activity. Substitution at the 7th position with electron donating group enhances the pharmacological activity whereas the electron withdrawing group decreases the pharmacological activity. Structural modifications at the chromene ring, middle aliphatic portion, and terminal aromatic ring yielded more potential 5-HT1A (5-Hydroxytryptamine 1A) receptor affinity and antidiabetic activity. Chromenes with cyclic secondary amine and 4-hydroxy phenyl substituents yielded potent antimicrobial compounds. This review summarizes the importance of chromenes in rational drug design and the development of novel molecules with a variety of pharmacological activities.

Background: Diabetes is one of the leading killers among noncommunicable diseases of the present time and poses a considerable burden to the society in terms of public health. The Indian Diabetes Risk Score (IDRS) can be used as a risk assessment tool to estimate the population at risk and plan appropriate interventions. The present study was conducted to assess the diabetes risk profile of a rural population of Punjab by using IDRS. Materials and Methods: This was a cross-sectional study conducted in two phases after obtaining approval from the Institutional Ethics Committee. Phase 1 was done in Rural Health Training Center (RHTC), Pohir, where every fifth patient attending the outpatient department was included in the study. Phase 2 was conducted in village Gopalpur, which is one of the villages in the field practice area of Department of Community Medicine, where participants were enrolled by conducting house to house survey after taking their informed consent. Sociodemographic characteristics, risk factor profile, and the IDRS of the participants were noted. The data was analyzed using Statistical Package for the Social Sciences (SPSS) version 26.0 to calculate the percentages. Pearson's Chi-square test was used for qualitative variables, and mean, standard deviation and analysis of variance (ANOVA) were used for quantitative variables. A P value of less than 0.05 was considered significant. Results: A total of 252 subjects (99 male and 153 female) from RHTC and 213 subjects (71 male and 142 female) from village Gopalpur participated in the study, with their mean IDRS being 44.8 ± 15.7 and 46.6 ± 21.1, respectively. On calculating the IDRS of participants enrolled in RHTC, it was found that 15.5% had low, 56% had moderate, and 28.5% had high risk, whereas from village Gopalpur, 19.2% had low, 57.3% had moderate, and 23.5% had high risk for developing diabetes mellitus. The risk for developing diabetes was found to be higher among females, subjects living in joint families, and subjects with high body mass index (BMI). The mean systolic and diastolic blood pressure showed an increasing trend with increase in IDRS score of the participants. Conclusion: The present study showed that even in rural areas, nearly one-fourth of the adult population was at high risk, whereas more than half of the population was at moderate risk of developing diabetes mellitus. This corroborates the World Health Organization's (WHO's) stand to declare diabetes as a public health emergency and to devise ways to urgently mitigate this problem. Therefore, awareness and health education campaigns should be implemented in rural areas for early identification of risks, which will help in prevention and hence decreasing the burden of the disease.
RESUMO
Context: The ongoing corona pandemic has created medical crises all over the world. An increased surge in the number of COVID-19 cases was observed in the month of August, September and October 2020. Punjab has around 10 Lakh migrant workers. Intensive rapid antigen testing was done during this surge among factory workers. With this background, the study aims to find out the positivity rate of rapid antigen testing and to find out the final outcome of the COVID positive cases in terms of morbidity. Materials and methods: Screening of factory workers working in various factories was done for COVID-19 by rapid antigen testing from 26th august to 31st October 2020. Those who tested positive were clinically examined, counseled, and followed up telephonically to get information regarding their course of illness. The collected information was entered in Microsoft excel sheet and analyzed using SPSS. Results: A total of 11045 factory workers were screened using the rapid antigen test. The mean age of subjects was 33.37 ± 10.97 years. The majority of them were males (88.3%) and migrants (who did not belong to Punjab) (97.3%). The majority of the subjects (97.3%) had no symptoms at the time of screening. COVID-19 positivity rate increased with age, was found to be higher in males (2.3%) as compared to females. Conclusion: The positivity rate was higher in asymptomatic males and local resident workers. Rapid antigen testing is an important public health measure to prevent the further spread of the disease during a pandemic due to its quick results and detection of asymptomatic patients.
RESUMO
Background: Hepatitis C virus (HCV) infection is considered one of the growing public health problems. Identification of HCV-associated risk factors is pivotal for developing appropriate prevention strategies. Objectives: To determine the epidemiological variables of HCV infection in a tertiary care hospital. Methods: This hospital-based case-control study was conducted in a tertiary care hospital in Punjab on 320 subjects, including 160 cases and controls each. Cases and controls were matched by age (±5 years), gender, and residence. A patient ≥18 years of age fulfilling the biomarker criteria with or without clinical criteria diagnosed in the last 1 month was considered as a case. The information on socio-demographic characteristics and previous exposures to selected risk factors was collected through detailed interviews of the subjects. Analysis was performed using SPSS 20 statistical software. Odds ratio (OR) with 95% confidence interval (CI) was calculated to measure the strength of association between cases and controls for each risk factor. Results: Odds of having HCV infection was significantly higher among those with a history of blood transfusion (OR: 2.30, 95%CI: 1.14-4.63), dental procedure (OR: 4.82, 95%CI: 2.38-9.77) and intravenous injection/infusion from quacks (OR: 3.26, 95%CI: 1.47-7.19), injectable drug use (OR: 26.69, 95%CI: 3.55-200.24), non-injectable drug use (OR: 2.37, 95%CI: 1.44-3.90), tattooing (OR: 7.91, 95%CI: 2.31-27.08), and piercing from street hawkers (OR: 2.25, 95%CI: 1.18-4.29). Multivariate analysis identified history of blood transfusion, dental procedure, intravenous injection/infusion from quacks, injecting drug use, and piercing as independent risk factors for HCV infection. Conclusion: The study identified multiple risk factors for acquiring HCV infection and suggest appropriate interventions targeting high-risk populations.
