Malaria/HIV-1 co-infection has become a significant public health problem in the tropics where there is geographical overlap of the two diseases. It is well described that co-infection impacts clinical progression of both diseases; however, less is known about the impact of co-infection on disease transmission. Malaria transmission is dependent upon multiple critical factors, one of which is the presence and viability of the sexual-stage gametocyte. In this review, we summarize evidence surrounding gametocyte production in Plasmodium falciparum and the development factors and the consequential impact that HIV-1 has on malaria parasite transmission. Epidemiological and clinical evidence surrounding anemia, immune dysregulation, and chemotherapy as it pertains to co-infection and gametocyte transmission are reviewed. We discuss significant gaps in understanding that are often due to the biological complexities of both diseases as well as the lack of entomological data necessary to define transmission success. In particular, we highlight special epidemiological populations, such as co-infected asymptomatic gametocyte carriers, and the unique role these populations have in a future focused on malaria elimination and eradication.

Background: Suicide is a significant public health problem worldwide that requires evidence-based prevention efforts. One approach to prevention is gatekeeper training. Gatekeeper training programs for community members have demonstrated positive changes in knowledge and attitudes about suicide. Changes in gatekeeper skills have not been well established. Aims: To assess and to predict the impact of a brief, gatekeeper training on community members’ observed skills. Methods: Participants in a community gatekeeper training were employees at US universities. 50 participants were randomly selected for skills assessment and videotaped interacting with a standardized actor prior to and following training. Tapes were reliably rated for general and suicide-specific skills. Results: Gatekeeper skills increased from pre- to posttest: 10% of participants met criteria for acceptable gatekeeper skills before training, while 54% met criteria after training. Pretraining variables did not predict increased skills. Limitations: Results do not provide conclusions about the relationship between observed gatekeeper skills and actual use of those skills in the future. Conclusions: Gatekeeper training enhances suicide-specific skills for the majority of participants. Other strategies, such as behavioral rehearsal, may be necessary to enhance skills in the remaining participants.

Cysticercosis is a significant public health problem in countries where pigs are raised for consumption and remains an important cause of neurological disease worldwide. The Philippines is considered an endemic area for cysticercosis because cases in both humans and pigs have been reported; however, epidemiologic information stays limited. We conducted a pilot survey of the seroprevalence of human cysticercosis in a village in Leyte, the Philippines, by measuring antibody specific forTaenia soliumcyst-fluid antigen. There were 497 subjects aged 7–30 years in our study and most subjects were infected with one or more helminths. The overall cysticercosis seroprevalence in this population was 24.6% (95% CI: 20.82% ~ 28.58%) with no significant difference based on age, sex, or other helminth coinfection status. Although the sample may not be representative of the whole community, the findings suggest that cysticercosis is a significant, but underrecognized public health concern in the Philippines.

Envenomation and death resulting from snakebites represent a significant public health problem worldwide, particularly in tropical and subtropical regions. The WHO has defined snakebite as a neglected tropical health concern. Bites from Macrovipera lebetina obtusa usually cause life-threatening systemic hemodynamic disturbances, reduced functionality of the kidneys, and other serious symptoms, including hypotension shock, edema, and tissue necrosis, at the bite site. Herein, we highlight five cases of M. l. obtusa envenomation that presented with wide-ranging manifestations. Many recovered cases were left with long-term musculoskeletal disabilities. In a particular case, a 15-year-old male patient was envenomed in his palm by an 80-cm M. l. obtusa. Within 12 hours, swelling extended to near the shoulder. Fasciotomy was performed on the forearm and part of the upper arm of this patient. Symptoms of severe localized pain and swelling, dizziness, weakness, low blood pressure, and itching around the bite area were documented. The patient remained in the hospital for 13 days.

Abstract Lead exposure remains a significant public health problem, particularly in the informal sector. Recycling of scrap metal into artisanal pots is a growing concern in poorly resourced countries. Owing to the relatively light weight and low cost of the artisanal pots, as well as good conductivity which equates to lower usage of wood fuel, the pots are widely used. The aim of this article is to describe current insights and emerging evidence of health risks associated with artisanal pot making and usage. This thriving industry, particularly in poorly resourced communities, has multifaceted occupational, environmental and human health impacts. Given the complexity, innovative solutions need to be prioritized, evaluated and scaled up in relevant settings.

Abstract Hydatid cyst is a zoonotic infection and a significant public health problem in low- and middle-income countries. A 79-year-old female patient was presented to the gynecology outpatient department with complaints of pain in the abdomen and difficulty in micturition, with a mass palpable per speculum. The ultrasound was suggestive of an ovarian cystadenocarcinoma, whereas computed tomography of the abdomen favored hydatid cyst with adnexal neoplasm as a differential diagnosis. Considering the contradictory findings, a frozen section was sent to confirm the diagnosis, which showed hooklets of Echinococcus granulosus/hydatid cyst under the microscope. This was a rare case of pelvic hydatid cyst mimicking ovarian malignancy and was associated with a less-preferred mode of investigation (frozen section). This article focuses on how a frozen section, despite its limitations and being expensive, can still be considered for accurate patient management.

AbstractAccording to the World Health Organization (WHO), viral diseases continue to rise, and pose a significant public health problem. Novel coronavirus disease (COVID-19) is an infectious disease caused by SARS-CoV-2. The pathogenesis and clinical manifestations of COVID-19 is close to Amraz-e-Wabai (epidemic diseases) which was described by Hippocrates, Galen, Aristotle, Razes, Haly Abbas, Avicenna, Jurjani etc. Presently, there is no specific or challenging treatment available for COVID-19. Renowned Unani Scholars recommended during epidemic situation to stay at home, and fumigate the shelters with aromatics herbs like Ood kham (Aquilaria agallocha Roxb.), Kundur (Boswellia serrata Roxb), Kafoor (Cinnamomum camphora L.), Sandal (Santalum album L), Hing (Ferula foetida L.) etc. Use of specific Unani formulations are claimed effective for the management of such epidemic or pandemic situation like antidotes (Tiryaqe Wabai, Tiryaqe Arba, Tiryaqe Azam, Gile Armani), Herbal Decoction (Joshandah), along with Sharbate Khaksi, Habbe Bukhar, Sharbate Zanjabeel, Khamira Marwareed, Jawarish Jalinus, and Sirka (vinegar). Such drugs are claimed for use as antioxidant, immunomodulatory, cardiotonic, and general tonic actions. The study enumerates the literature regarding management of epidemics in Unani medicine and attempts to look the same in the perspective of COVID-19 prevention and management.

ObjectivesTo identify the prevalence, methods, associations and reported reasons for self-harm among in-school and street-connected adolescents in Ghana.DesignA cross-sectional survey. We applied multi-level regression models and model-based cluster analysis to the data.SettingThree contexts in the Greater Accra region were used: second cycle schools, facilities of charity organisations and street census enumeration areas (sleeping places of street-connected adolescents, street corners, quiet spots of restaurants, markets, train and bus stations, and lorry and car parks).ParticipantsA regionally representative sample of 2107 (1723 in-school and 384 street-connected) adolescents aged 13–21 years.Outcome measuresParticipants responded to a structured self-report anonymous questionnaire describing their experience of self-harm and eliciting demographic information and social and personal adversities.ResultsThe lifetime prevalence of self-harm was 20.2% (95% CI 19.0% to 22.0%), 12-month prevalence was 16.6% (95% CI 15.0% to 18.0%) and 1-month prevalence was 3.1% (95% CI 2.0% to 4.0%). Self-injury alone accounted for 54.5% episodes and self-poisoning alone for 16.2% episodes, with more than one method used in 26% of episodes. Self-cutting (38.7%) was the most common form of self-injury, whereas alcohol (39.2%) and medications (27.7%) were the most commonly reported means of self-poisoning. The factors associated with self-harm were interpersonal: conflict with parents (adjusted OR (aOR)=1.87, 95% CI 1.24 to 2.81), physical abuse victimisation (aOR=1.69, 95% CI 1.16 to 2.47), difficulty in making and keeping friends (aOR=1.24, 95% CI 0.85 to 1.80), sexual abuse victimisation (aOR=1.21, 95% CI 0.78 to 1.87) and conflict between parents (aOR=1.07, 95% CI 0.73 to 1.56).ConclusionsSelf-harm is a significant public health problem among in-school and street-connected adolescents in the Greater Accra region of Ghana. Its origins are very largely in social and familial adversity, and therefore prevention and treatment measures need to be focused in these areas.

Background: Female sexual dysfunction (FSD) has mainly been underdiagnosed and undertreated due to the lack of concrete definitions, validated assessment methods, and efficient treatments. However, during the last few decades, there has been significant progress in the clinical management and research of FSD. Objective: The purpose of this review is to describe the pathophysiology of FSD, report the prevalence of the disease in the setting of cardiovascular (CV) risk factors and disease, and review current and under investigation treatment options. Methods: A comprehensive literature review was performed to identify studies examining the association of FSD with CV risk factors and/or disease and studies reporting appropriate management options. Results: The prevalence of FSD is increased in the general population (approximately 40%) and is significantly higher in patients with hypertension, diabetes mellitus, and dyslipidemia. In patients with overt CV disease, FSD is even more prevalent (up to 90%). The cause of FSD is multifactorial and includes various vascular, hormonal, interpersonal, and psychological factors, which are all intertwined. Several treatment options exist that are efficient in improving female sexual function, while a cluster of other alternatives has been shown to offer benefits. Conclusion: FSD is a significant public health problem with a great impact on the patients’ quality of life. In the setting of increased CV burden, FSD is even more prevalent. Increased awareness is needed for the physician to establish a trustful environment with the patient, discuss such issues, and offer suitable management options.

Purpose The purpose of this paper is to explore the role of fathers in the management of sleeping problems in children with autism and their perspectives of the impact of these difficulties on family life. Design/methodology/approach Semi-structured interviews with 25 UK-based fathers of children with autism were undertaken. Findings Two-thirds of fathers reported that their children experienced severe sleeping problems in the areas of bed-time resistance, sleep onset and night-time waking. Fathers were significantly involved in the management of these difficulties and reported a range of associated deleterious impacts on the family, including significant negative effects on paternal and maternal health, father’s employment, couple relationship and sibling experiences. Research limitations/implications The interview sample cannot be said to be representative of all fathers of children with autism since the backgrounds of those taking part were relatively homogeneous in respect of ethnicity, marital status and level of education. Practical implications Improvements in effective, family-centred provision are urgently needed which employ a co-parenting, gender-differentiated methodology. Social implications Given the severity and frequency of difficulties, sleeping problems in children with autism should be viewed as a significant public health concern. Originality/value This is one of the first studies, qualitative or quantitative, to explore the role and perspectives of fathers of children with autism in the important area of sleep management.

INTRODUCTION: The prevalence and intensity of geohelminth infections and schistosomiasis remain high in the rural areas of Zona da Mata, Pernambuco (ZMP), Brazil, where these parasites still represent a significant public health problem. The present study aimed to spatially assess the occurrences of schistosomiasis and geohelminthiasis in the ZMP. METHODS: The ZMP has a population of 1,132,544 inhabitants, formed by 43 municipalities. An ecological study was conducted, using secondary data relating to positive human cases and parasite loads of schistosomiasis and positive human cases of geohelminthiasis that were worked up in Excel 2007. We used the coordinates of the municipal headquarters to represent the cities which served as the unit of analysis of this study. The Kernel estimator was used to spatially analyze the data and identify distribution patterns and case densities, with analysis done in ArcGIS software. RESULTS: Spatial analysis from the Kernel intensity estimator made it possible to construct density maps showing that the northern ZMP was the region with the greatest number of children infected with parasites and the populations most intensely infected by Schistosoma mansoni. In relation to geohelminths, there was higher spatial distribution of cases of Ascaris lumbricoides and Trichuris trichiura in the southern ZMP, and greater occurrence of hookworms in the northern/central ZMP. CONCLUSIONS: Despite several surveys and studies showing occurrences of schistosomiasis and geohelminthiasis in the ZMP, no preventive measures that are known to have been effective in decreasing these health hazards have yet been implemented in the endemic area.
