Background: Parents play a vital role in the sexual and reproductive health (SRH) of adolescents. Parents’ communication with their adolescents regarding SRH is considered an important part of adolescent development, as this contributes to optimising safe SRH. Aim: This phase of the study explored the culturally sensitive SRH information communication skill needs of parents, based on their personal and social motivation, within the Ghanaian context. Setting: The study was conducted at the Asante Akyem North Municipality of Ghana. Methods: This article describes the second phase of an explanatory, sequential, mixed-method study. Following on from the first phase systematic review, this second phase comprised a qualitative descriptive study where 10 purposively sampled parents of adolescents participated in semi-structured interviews to elicit data. Braun and Clarke’s thematic data analysis process was applied. Data were saved and managed in Atlas.ti (version 23.0.7). Results: Four themes emerged on communication skills: SRH information, parent and adolescent factors, contextual factors and communication skill needs. Parent and adolescent communication on SRH takes place occasionally. Parents lack the skills to communicate with adolescents regarding SRH. Conclusion: Parents in this context require skills to communicate SRH information with their adolescent children. A culturally appropriate intervention that supports SRH information communication between parents and adolescents may have value in guiding this communication process. Contribution: The findings of this study can contribute to the adaptation of a culturally sensitive SRH information communication intervention in Ghana which will promote adolescent SRH.

Mosquitoes are a dominant fraction of dipteran fauna, occupying a variety of niches. The most common method deployed for their control is the use of insecticides. Throughout their life cycle they are exposed to a wide range of predators in different habitats, thus biological control of mosquitoes by using aquatic predators has been suggested. Therefore, the present study was carried out to explore the type of natural predators coexisting with the mosquito larvae in still water bodies and to determine their efficacy as predators for mosquito larvae. A coexistence of different predators with mosquito larvae was observed in 27 standing water bodies of Chandigarh, India. The predation efficiency of tadpoles of frog was comparable to Gambusia fish, as 97% of the mosquito larvae of all instars of the medically important mosquito genera Anopheles, Aedes, Culex and Armigeres were preyed. The toad tadpoles were found to be least effective and their predation rate was found to be negligible. Further studies on larval source management by frog tadpoles in combination with insecticides or stand-alone would be worthwhile.

Background: A dermoid cyst can be defined as a confined cavity that contains dermal adnexal structures, such as sebaceous glands, hair follicles, or sweat glands, with a distinct epithelial lining. A congenital dermoid cyst arises from the entrapment of pluripotential ectodermal cells along the lines of fusion between the first and second branchial arches during embryonic life. Case Report: This report presented the case of a 25-year-old woman who complained of a painless swelling on the floor of the mouth that had lasted for 6 years. An examination revealed ovoid submental swelling extending to the sublingual and submandibular spaces measuring 10 cm × 7 cm × 5 cm with intact skin. The swelling was soft, mobile, and non-tender upon palpation. Intraorally, it occupied the floor of the mouth and displaced the tongue superiorly. A yellowish crystalline aspirate was noted. Ultrasonography revealed a huge, thick-walled, deep-seated cystic mass showing florid mobile internal echoes and few separations on a turbid background with no intracystic solid components or calcification. A posterior–anterior view of the jaws revealed no bony involvement. Conclusion: A dermoid cyst can lead to difficulty in mastication, speech, respiration, and esthetic concerns if left untreated for a very long time. Early diagnosis and treatment can help prevent the occurrence of such complications. Despite, the late treatment in this case report, a successful treatment outcome was achieved.

Background & objectives: Malaria transmission in Punjab, India is mainly seasonal with variation in its endemicity that may be due to varying vector behaviour in different areas of the state, primarily attributed to the existence of sibling species complexes among the vector species. So far there is no report regarding the existence of malaria vectors sibling species in the state of Punjab, therefore, the present study was planned to investigate the status of sibling species of two main vectors of malaria viz. Anopheles culcifacies and Anopheles fluviatilis in different districts of Punjab. Methods: Mosquito collections were made through hand catch in the morning hours. Malaria vector species An. culicifacies and An. fluviatilis were morphologically identified and man hour density was calculated. Both the vector species were subjected to molecular assays for sibling species identification through amplification of D3 domain of 28S ribosomal DNA by allele-specific PCR. Results: Four sibling species of An. culicifacies, were identified viz. A, B, C and E. Species A was identified from Bhatinda district, species B, C and E from. S.A.S. Nagar and species C from Hoshiarpur. Two sibling species S and T of An. fluviatilis were identified from districts S.A.S. Nagar and Rupnagar. Interpretation & conclusion: Presence of four sibling species of An. culicifacies and two sibling species of An. fluviatilis in Punjab necessitates planning of longitudinal studies to ascertain their role in disease transmission so that appropriate interventions may be applied to achieve malaria elimination.

Abstract Background Dental diseases have detrimental effects on healthcare systems and societies at large. Providing access to dental care can arguably improve health outcomes, reduce healthcare utilization costs, and improve several societal outcomes. Objectives Our objective was to review the literature to assess the impacts of dental care programs on healthcare and societal outcomes. Specifically, to identify the nature of such programs, including the type of services delivered, who was targeted, where services were delivered, and how access to dental care was enabled. Also, what kind of societal and healthcare outcomes have been attempted to be addressed through these programs were identified. Methods We conducted a scoping review by searching four databases, MEDLINE, EMBASE, CINAHL, and Sociological Abstracts. Relevant articles published in English language from January 2000 to February 2022 were screened by four reviewers to determine eligibility for inclusion. Results The search resulted in 29,468 original articles, of which 25 were included in the data synthesis. We found minimal evidence that answers our proposed research question. The majority of identified programs have demonstrated effectiveness in reducing medical and dental healthcare utilization (especially for non-preventive services) and avert more invasive treatments, and to a lesser degree, resulting in cost-savings. Moreover, some promising but limited evidence about program impacts on societal outcomes such as reducing homelessness and improving employability was reported. Conclusion Despite the well-known societal and economic consequences of dental problem, there is a paucity of studies that address the impacts of dental care programs from the societal and healthcare system perspectives. MeSH terms Delivery of Health Care, Dental Care, Outcome assessment, Patient acceptance of Health Care.

Background: Parents play an important role in the sexual and reproductive health (SRH) of their adolescents. Parent–adolescent SRH information communication is cardinal and is expected to improve SRH outcomes of adolescents. Aim: The aim of this systematic review was to search for effective SRH information communication interventions in lower- and middle-income countries (LMICs) to inform the adaptation of parent–adolescent SRH information communication intervention. Method: This is the first phase of an explanatory sequential mixed method study. The systematic review was carried out by employing Joanna Briggs Institute software for reviews. Search sources included Cochrane Reviews Library, EMBASE, CINAHL, PubMed, OVID, Scopus, Web of Science and Science Direct. A systematic search strategy was formulated, making use of the key terms: adolescent, teenager, youth, parent, mother, father, caregiver, reproductive, sexual, health, information, communication and intervention. Results: Five articles met the inclusion criteria for full-text screening. The interventions included addressed sociodemographic covariates; parent–adolescent general communication; parental monitoring; parent–adolescent communication about sex-related topics; parent’s sexual communication skills; parent’s self-efficacy in sexual communication; parent’s responsiveness to sexual communication; communication frequency; quality of sex‑related communication and information-motivational-behavioural skills. Conclusion: Findings suggest that evidence-based SRH information communication interventions are effective in improving parent–adolescent SRH information communication to optimise safe SRH behaviour in LMICs. Contribution: This systematic review identified effective SRH information communication interventions in LMICs, which can form the basis of further qualitative exploration for adaptation of a culturally sensitive intervention in Ghana.

Aberrant wound healing presents as inappropriate or insufficient tissue formation. Using a model of musculoskeletal injury, we demonstrate that loss of transforming growth factor-β activated kinase 1 (TAK1) signaling reduces inappropriate tissue formation (heterotopic ossification) through reduced cellular differentiation. Upon identifying increased proliferation with loss of TAK1 signaling, we considered a regenerative approach to address insufficient tissue production through coordinated inactivation of TAK1 to promote cellular proliferation, followed by reactivation to elicit differentiation and extracellular matrix production. Although the current regenerative medicine paradigm is centered on the effects of drug treatment ("drug on"), the impact of drug withdrawal ("drug off") implicit in these regimens is unknown. Because current TAK1 inhibitors are unable to phenocopy genetic Tak1 loss, we introduce the dual-inducible COmbinational Sequential Inversion ENgineering (COSIEN) mouse model. The COSIEN mouse model, which allows us to study the response to targeted drug treatment ("drug on") and subsequent withdrawal ("drug off") through genetic modification, was used here to inactivate and reactivate Tak1 with the purpose of augmenting tissue regeneration in a calvarial defect model. Our study reveals the importance of both the "drug on" (Cre-mediated inactivation) and "drug off" (Flp-mediated reactivation) states during regenerative therapy using a mouse model with broad utility to study targeted therapies for disease.

BackgroundDigital tools are increasingly used on a population level as a weight loss strategy for people living with overweight and obesity. Evidence supports the feasibility of digital tools for the management of obesity in a community setting, but there is only emerging evidence for the feasibility of such tools in specialist weight management services. No study has assessed the uptake of digital tools among patients awaiting their first appointment with a specialist weight management service. ObjectiveThe objective of this study was to understand interest, acceptance, and engagement with a digital behavioral change platform to support specialist weight management. MethodsThis was an observational study registered as a service innovation. All patients on the waiting list for a first appointment in the tier 3 weight management service at University Hospitals Coventry and Warwickshire National Health Service (NHS) Trust were eligible to access the NHS-approved digital tool. Data on interest and engagement with the digital tool were collected. Routine clinical data were used to describe patient demographics. Focus groups were held to explore patients’ views on the use of digital tools as part of a specialist weight management service. ResultsA total of 199 patients on the waiting list were informed about the available digital tool. Just over a half (n=102, 51.3%) of patients were interested in using the app, with over one-third (n=68, 34%) of all patients engaging with the app. Overall, a third of patients on the waiting list (n=63, 32%) did not respond to the invite and 34 (17%) of patients expressed no interest in the app. Emotional eating and higher BMI was associated with interest in the Gro Health app. Male gender was associated with reduced engagement with the app. There were no differences in interest in the Gro Health app according to age, ethnicity, metabolic measures of glycemia, and lipid profile. ConclusionsIt is feasible to offer digital tools such as Gro Health to patients awaiting their first appointment with specialist weight management services. Future research should explore barriers and facilitators of engagement with digital tools. Additionally, there is a need to further evaluate the effectiveness of such tools in specialist weight management services.

Background & objectives: Scrub typhus or chigger borne typhus, caused by Orientia tsutsugamushi is an emerging vector-borne disease as large numbers of cases have been reported in various tropical countries. It is transmitted to humans through bites of infected chiggers (larval mites). The knowledge about the vector, its distribution, density and habitat are important so as to understand the epidemiology of scrub typhus in a given area. To control rickettsial infections, regular rodent-vector surveillance should be planned in areas where the disease transmission is occurring and it will also help to strengthen the existing entomological data related to the vector of scrub typhus in northern India. Methods: In the present study, rodent-vector surveillance was planned for one whole year, covering both mite active and non-active seasons (October 2019-December 2020) in selected areas of Chandigarh and Punjab in north India. Rodent tissues and mites were also examined for the presence of O. tsutsugamushi by nested PCR for 56 kDa gene and real-time PCR for 47 kDa outer membrane protein gene. 18S gene PCR was performed for molecular identification of mites. Results: In the surveillance, three types of ectoparasite, viz. mites, fleas and ticks were obtained in rodents. All mites found were of Laelapidae family. None of the pooled rodent tissue samples as well as mite samples were found positive for O. tsutsugamushi by nested PCR for rickettsial DNA. Interpretation & conclusion: In the present study, we did not get any evidence of carriage of O. tsutsugamushi in either mites or rodents collected and sampled in selected regions in Chandigarh and Punjab. We need to strengthen the entomological surveillance over a broader region and increase the frequency of trapping rodents to increase clarity on vector-reservoir dynamics in this geographical region.

Introduction: Breakthrough infections in fully vaccinated persons pose a major challenge to the ongoing vaccine campaign against SARS-CoV-2 globally. Objectives: To investigate the occurrence of breakthrough infections and the association of Covid symptoms with the vaccination status of health care workers (HCWs). Material and Methods: Done in Government Medical College, Patiala among Covid-positive HCWs who have received one or both doses of Covid vaccine, using pretested semi-structured validated Proforma and telephonic interview from April 1, 2021 to June 15, 2021. Results: Among 3388 HCWs, 115 vaccinated HCWs (1st or 2nd dose) became Covid positive. Among vaccinated Covid positive HCWs, 54 received the first dose and 61 both doses. Breakthrough infections (≥14 days post 2nd dose) occurred in 4.6% (47 of 1021) HCWs. The vaccine is significantly protective as shown by an odds ratio of 0.27; thus, vaccinated HCWs are 73% less likely to get Covid infection as compared to non-vaccinated HCWs. There was no statistically significant difference between symptom profiles of cases whether they took one or both doses of vaccine, except headache. Only tiredness and headache were reported significantly higher in the unvaccinated group in comparison to vaccinated HCWs. Conclusion; Research is needed on tracking the immune response and viral genomic sequence of samples of vaccinated Covid-positive HCWs to have constant vigilance on remerging new strains of the SARS-CoV-2.

Background and Aims: Previous large studies on the epidemiology and clinical profile of chronic pancreatitis have suggested significant differences in presentation and management in the eastern and western hemispheres. The aim of this systematic review was to compare large multicenter studies across different geographic regions of the world to detect meaningful differences in the presentation and management of this poorly understood disease. Methods: We identified 237 manuscripts through a comprehensive literature review aiming to identify multicenter studies enrolling more than 200 patients to limit reporting biases. After rigorous screening, 12 studies were included for the final analysis. The Asian studies were included in the eastern cohort, and the European and American studies were included in the western cohort. Reported demographics, risk factors, etiologies, clinical presentation, complications, and management strategies were then compared. Results: We found similar demographics across both cohorts including age, prevalence among gender, and predominant etiology. Clinical manifestations including pain, pancreatic calcifications, and diabetes were similar between both cohorts although pseudocysts, pancreatic cancer, and strictures were more common in the west. Notably opioids and surgical/endotherapy management were more common in the west as well. Conclusion: Chronic pancreatitis is a protracted disease affecting predominantly middle-aged people, leading to a decreased quality of life. Chronic pancreatitis now appears to have a fairly similar clinical profile and natural history in the east and west. There is notable variability in management. We hope that international collaboration may identify common targets for research which could lead to significant advances in the understanding and management of chronic pancreatitis.

Overdoses are increasing in the province of Ontario, Canada, where northern communities such as Sudbury have witnessed disproportionately elevated rates, with opioid-related deaths double that of the provincial average. To address this issue, governments have implemented supervised consumption services (SCS) where people who use drugs (PWUD) can use their pre-obtained substances onsite under trained supervision. In September 2022, the city of Sudbury opened its first SCS, 'The Spot', but the site's sustainability is contingent on demonstrating benefit to PWUD and the neighboring community. We undertook a qualitative study exploring experiences among clients who used the consumption service inside The Spot. In December 2022, clients of The Spot were invited to participate in a brief survey which collected socio-demographic information and substance use profiles, followed by an in-person semi-structured qualitative interview. Participant survey and interview data were combined with administrative site utilization data provided by site staff of all clients who accessed the consumption service from September 2022 to August 2023 to examine overall service utilization and uptake. Qualitative data were analyzed using iterative thematic analysis techniques, and results were informed by common responses to research questions. The responses were narratively presented. Administrative site utilization data highlighted a relatively stable increase in uptake and utilization of the site since its inception. A total of 20 clients participated in the survey and semi-structured interviews. Participants described the importance of the site in preventing and responding to overdoses, providing a safe and comfortable environment to consume their drugs, and decreasing public drug use, which they suggested may potentially reduce stigmatization in the community. However, clients also suggested challenges, including issues regarding site operational policies that hindered consumption room utilization. Service suggestions made by clients to improve site utilization include the addition of inhalation services, relocating the site to a location in downtown Sudbury where PWUD commonly congregate, and extending operational hours. Positive impacts and recommendations can be drawn on and considered by other northern or rural communities interested in implementing similar harm reduction services.

Background: Continuity and coordination of care are core principles of high-quality primary health care. Optimising continuity and coordination improves maternal satisfaction. However, their association with morbidity and mortality outcomes is unclear. The obstetric near-miss approach can be used to investigate whether continuity and coordination influences the occurrence of a severe maternal outcome. Aim: To compare self-reported continuity and coordination of care between obstetric near-miss survivors and those without near miss during pregnancy, delivery and postpartum. Setting: Uasin Gishu county, Rift Valley region, Kenya. Methods: A cross-sectional survey targeting 340 postnatal mothers. Continuity of care index (COCI) and modified continuity of care index (MCCI) were used to estimate longitudinal continuity. The Likert scale was administered to measure perceived continuity and coordination of care. Mann–Whitney U test and binomial logistic regression were used for hypothesis testing. Results: COCI and MCCI were lower among near-miss survivors (COCI = 0.80, p = 0.0026), (MCCI = 0.62, p = 0.034). Near-miss survivors scored lower on items assessing coordination between a higher-level provider and usual antenatal clinic (mean = 3.6, p = 0.006) and general coordination of care during pregnancy (mean = 3.9, p = 0.019). Presence of a non-life-threatening morbidity in pregnancy was associated with occurrence of near miss (aOR = 4.34, p = 0.001). Conclusion: Near-miss survivors scored lower on longitudinal continuity and coordination of care across levels. Further research should focus on strengthening coordination, determining the optimal level of longitudinal continuity and improving systems for early identification and management of morbidities in pregnancy. Contribution: The results of this study show that while longitudinal and relational COC is important during the antenatal period, the presence of a non-life-threatening condition in pregnancy remains the most important predictor of the occurrence of a near miss.
