RESUMO

Purpose: To describe ocular sarcoid-like reaction as a unique manifestation of paraneoplastic syndrome in the context of concurrent pulmonary sarcoid-like reaction and lung adenocarcinoma. Methods: Single case report and narrative review. Results: A 59-year-old male patient presented with a year-long history of diminished vision and weight loss. Clinical examination revealed panuveitis and multiple chorioretinal lesions. A CT scan of the chest revealed mediastinal and hilar lymphadenopathy as well as a spiculated right lower lung nodule concerning for malignancy. Subsequent bronchoscopy and biopsy confirmed lung adenocarcinoma and non-caseating granulomas in sentinel lymph nodes. Conclusion: Although pulmonary granulomatous reaction can be seen in the setting of lung malignancy, and ocular sarcoid-like reaction may present as a paraneoplastic manifestation of systemic malignancy, the presence of concomitant pulmonary and ocular sarcoid-like reactions distinguishes this case. The findings underscore the importance of a systemic workup for patients with concerning constitutional symptoms, as paraneoplastic syndromes and metastatic diseases may mimic uveitis. Recognition of paraneoplastic sarcoidosis as a potential clinical manifestation is essential, especially in patients with chronic illness indicators, necessitating a comprehensive evaluation for malignancy.

RESUMO

BACKGROUND: Enduring ethnic inequalities exist in mental healthcare. The COVID-19 pandemic has widened these. AIMS: To explore stakeholder perspectives on how the COVID-19 pandemic has increased ethnic inequalities in mental healthcare. METHOD: A qualitative interview study of four areas in England with 34 patients, 15 carers and 39 mental health professionals from National Health Service (NHS) and community organisations (July 2021 to July 2022). Framework analysis was used to develop a logic model of inter-relationships between pre-pandemic barriers and COVID-19 impacts. RESULTS: Impacts were largely similar across sites, with some small variations (e.g. positive service impacts of higher ethnic diversity in area 2). Pre-pandemic barriers at individual level included mistrust and thus avoidance of services and at a service level included the dominance of a monocultural model, leading to poor communication, disengagement and alienation. During the pandemic remote service delivery, closure of community organisations and media scapegoating exacerbated existing barriers by worsening alienation and communication barriers, fuelling prejudice and division, and increasing mistrust in services. Some minority ethnic patients reported positive developments, experiencing empowerment through self-determination and creative activities. CONCLUSIONS: During the COVID-19 pandemic some patients showed resilience and developed adaptations that could be nurtured by services. However, there has been a reduction in the availability of group-specific NHS and third-sector services in the community, exacerbating pre-existing barriers. As these developments are likely to have long-term consequences for minority ethnic groups' engagement with mental healthcare, they need to be addressed as a priority by the NHS and its partners.

RESUMO

PURPOSE: A college degree is required to enter medical school in the United States. A remarkably high percentage of students entering college have pre-medical aspirations but relatively few end up as medical students. As an "applied science", education about medicine is usually thought to be beyond the purview of a liberal arts curriculum. Students therefore receive little education about a medical career, or information about the many alternative careers in health science. Instead, they take courses for Medical College Admission Test (MCAT) preparation and medical school application prerequisites in biology, chemistry, physics, and math. These classes give them little insight into a real medical career. The current report considers this mismatch between student needs in health science and available resources in colleges across the United States. METHODS: A Collective Case Series framework was used to obtain qualitative data. Key informant interviews were requested from a convenience sample of representatives from 20 colleges, with six colleges providing extensive data. Three institutions collected data specifically on students who matriculated college interested in a career as a physician. RESULTS: At these schools, one-half to one-quarter of students who said they were interested in medicine at the beginning of college ended up not applying to medical school. At each of the six schools, we saw a wide range of generally sparse academic and professional advising involvement and a very limited number of classes that discussed concepts directly related to careers in health science. CONCLUSIONS: Looking at this data, we provide a novel conceptual model as a potential testable solution to the problem of an underexposed and unprepared student population interested in medicine. This includes a brief series of courses intended to inform students about what a career in medicine would fully entail to help foster core competencies of empathy, compassion and resilience.

RESUMO

BACKGROUND: Little information is available on the prevalence of cognitive impairment in Mexican American persons. OBJECTIVE: To determine the prevalence of mild cognitive impairment (MCI) and dementia in those 65 years and older among Mexican American and non-Hispanic white individuals in a community. METHODS: This was a population-based cohort study in Nueces County, Texas, USA. Participants were recruited using a random housing sample. The Harmonized Cognitive Assessment (HCAP) participant and informant protocol was performed after Montreal Cognitive Assessment (MoCA) screening. An algorithm was used to sort participants into diagnostic categories: no cognitive impairment, MCI, or dementia. Logistic regression determined the association of ethnicity with MCI and dementia controlling for age, gender, and education. RESULTS: 1,901 participants completed the MoCA and 547 the HCAP. Mexican Americans were younger and had less educational attainment than non-Hispanic whites. Overall, dementia prevalence was 11.6% (95% CI 9.2-14.0) and MCI prevalence was 21.2% (95% CI 17.5-24.8). After adjusting for age, gender, and education level, there was no significant ethnic difference in the odds of dementia or MCI. Those with ≤11 compared with ≥16 years of education had much higher dementia [OR = 4.9 (95% CI 2.2-11.1)] and MCI risk [OR = 3.5 (95% CI 1.6-7.5)]. CONCLUSIONS: Dementia and MCI prevalence were high in both Mexican American and non-Hispanic white populations. Mexican American persons had double the odds of mild cognitive impairment and this was attenuated when age and educational attainment were considered. Educational attainment was a potent predictor of cognitive impairment.

RESUMO

The impact of the COVID-19 pandemic on informal caregiving was examined in a Mexican American (MA) and Non-Hispanic White (NHW) population-based cohort. 395 participants age > 65 years were recruited via door-to-door and phone recruitment as part of the Brain Attack Surveillance in Corpus Christi-Cognitive (BASIC-C) project. Both recipients and caregivers answered questions regarding the recipient's health and the COVID-19 pandemic. 15% of caregivers saw their caregiving recipient less than before the pandemic and 18% saw their recipient more than before. 55% of caregivers reported a slight to severe impact of the pandemic on their caregiving, and 45% reported no impact. For most caregivers, their caregiving role did not change markedly during the pandemic. MA and NHW caregivers had similar survey responses.

RESUMO

BACKGROUND: Understanding concordance between informants' and cognitively impaired participants' information reporting is crucial for Alzheimer's and Alzheimer's-related dementia studies. METHODS: The Brain Attack Surveillance in Corpus Christi-Cognitive is a community-based cohort study. Households in Nueces County, Texas, USA, were randomly identified. 330 dyads of participants and their named informants answered questions. Models were generated to examine which predictors, including age, gender, ethnicity, cognitive function, and relationship to informant, influenced answer discordance. RESULTS: For demographic items, female participants and participants with spouses/partners as informants had significantly less discordance, with incidence rate rations (IRRs) of 0.65 (CI = 0.44, 0.96) and 0.41 (CI = 0.23, 0.75), respectively. For health items, better cognitive function of the participant was associated with less discordance, with an IRR of 0.85 (CI = 0.76, 0.94). CONCLUSIONS: Demographic information concordance is most associated with gender and informant-participant relationship. Level of cognitive function is most associated with concordance for health information. CLINICALTRIALS: gov identifier NCT03403257.

RESUMO

PURPOSE: To review the visual and anatomical outcomes of combined anterior and posterior segment surgery for retinal detachment repair. METHODS AND PATIENTS: Eight patients with combined retinal and corneal disease underwent combined temporary keratoprosthesis with penetrating keratoplasty combined with pars plana vitrectomy for retinal detachment repair with silicone oil tamponade. Visual and anatomical outcomes were reviewed retrospectively. Follow-up ranged from 12 months to 37 months. RESULTS: Preoperative visual acuity ranged from light perception to hand motion. All but one case had proliferative vitreoretinopathy present at the time of surgery. Postoperative visual acuity ranged from hand motion to light perception. At the most recent follow-up visit, all of the patients had attached retinas, no patients had phthisis bulbi, and all but one patient had a clear cornea. However, 3 of these cases (38%) required repeat retinal detachment repair and one of them also required repeat penetrating keratoplasty, which was performed at the time of retinal repair. CONCLUSION: Combined full-thickness penetrating keratoplasty and retinal detachment repair has good anatomical outcomes and is an efficient way to treat complex anterior and posterior segment abnormality. Although postoperative visual function is limited; almost all patients were agreeable to repeat surgery if they were presented with the choice again.

RESUMO

Background and motivation: Over the last two decades, particularly in the Middle East, Red Palm Weevils (RPW, Rhynchophorus ferruginous) have proved to be the most destructive pest of palm trees across the globe. Problem: The RPW has caused considerable damage to various palm species. The early identification of the RPW is a challenging task for good date production since the identification will prevent palm trees from being affected by the RPW. This is one of the reasons why the use of advanced technology will help in the prevention of the spread of the RPW on palm trees. Many researchers have worked on finding an accurate technique for the identification, localization and classification of the RPW pest. This study aimed to develop a model that can use a deep-learning approach to identify and discriminate between the RPW and other insects living in palm tree habitats using a deep-learning technique. Researchers had not applied deep learning to the classification of red palm weevils previously. Methods: In this study, a region-based convolutional neural network (R-CNN) algorithm was used to detect the location of the RPW in an image by building bounding boxes around the image. A CNN algorithm was applied in order to extract the features to enclose with the bounding boxes-the selection target. In addition, these features were passed through the classification and regression layers to determine the presence of the RPW with a high degree of accuracy and to locate its coordinates. Results: As a result of the developed model, the RPW can be quickly detected with a high accuracy of 100% in infested palm trees at an early stage. In the Al-Qassim region, which has thousands of farms, the model sets the path for deploying an efficient, low-cost RPW detection and classification technology for palm trees.

RESUMO

Older adults with significant cognitive impairment require help with activities of daily living. The BASIC-Cognitive Project, set in Nueces County, Texas, is a community-based study examining trends in cognition among Mexican Americans and non-Hispanic Whites. Using cross-sectional data from a cohort study, we found that at least 7% of individuals aged 65 and older with a Montreal Cognitive Assessment (MoCA) score of < 20 (or < 15 for telephone MoCA), did not receive any caregiving help. This conservative estimate highlights an important community need for those with significant cognitive impairment and has implications regarding safety and care for older adults.

RESUMO

Flavonoids are phytochemical compounds present in many plants, fruits, vegetables, and leaves, with potential applications in medicinal chemistry. Flavonoids possess a number of medicinal benefits, including anticancer, antioxidant, anti-inflammatory, and antiviral properties. They also have neuroprotective and cardio-protective effects. These biological activities depend upon the type of flavonoid, its (possible) mode of action, and its bioavailability. These cost-effective medicinal components have significant biological activities, and their effectiveness has been proved for a variety of diseases. The most recent work is focused on their isolation, synthesis of their analogs, and their effects on human health using a variety of techniques and animal models. Thousands of flavonoids have been successfully isolated, and this number increases steadily. We have therefore made an effort to summarize the isolated flavonoids with useful activities in order to gain a better understanding of their effects on human health.

RESUMO

BACKGROUND: Collaborations among researchers, clinicians, and individuals with mental illness from high-income countries (HICs) and low- and middle-income countries (LMICs) are crucial to produce research, interventions, and policies that are relevant, feasible, and ethical. However, global mental health and cultural psychiatry research publications have been dominated by HIC investigators. OBJECTIVE: The aim of this review was to present recommendations for collaborative writing with a focus on early career investigators researchers in HICs and LMICs. METHODS: A workshop was conducted with HIC and LMIC investigators in Nepal to discuss lessons learned for collaborative writing. The researchers had experience in cross-cultural psychiatric epidemiology, health services research, randomized controlled trials, and projects with war and disaster-affected populations in complex humanitarian emergencies including child soldiers and refugees. Additional lessons learned were contributed from researchers engaged in similar collaborations in Haiti. FINDINGS: A step-by-step process for collaborative writing was developed. CONCLUSIONS: HIC and LMIC writing collaborations will encourage accurate, ethical, and contextually grounded publications to foster understanding and facilitate reduction of the global burden of mental illness.

RESUMO

BACKGROUND: Fractures of the mandibular angle are common and comprise 31% of all mandibular fractures. Multiple recent studies report a 2-3 fold increased risk for mandibular angle fractures when un-erupted mandibular third molars are present. The objective of this study was to assess the frequency of un-erupted mandibular third molar in mandibular angle fractures. METHODS: This cross-sectional study was conducted at the Department of Oral and Maxillofacial Surgery, Ayub Medical College, Abbottabad from April to October 2009. One hundred and two patients were included both from the outdoor and ward on consecutive non-probability sampling base. Data were recorded on a structured Performa and analysed using SPSS-16. RESULTS: A hemi-mandible containing un-erupted mandibular third molar was seen to have a 1.41 times the risk of mandibular angle fracture then a hemi-mandible containing an erupted mandibular third molar. CONCLUSION: The presence of unerupted mandibular third molar is associated with an increased risk for mandibular angle fracture.

RESUMO

Smoking has been associated, in epidemiological studies, with an increased risk of cervical neoplasia. This may be in part due to the presence of tobacco-specific nitrosamines in cervical mucous of smokers, which may result in carcinogenic DNA damage. We have thus examined whether cervical DNA contains alkylation damage arising from exposure to methylating agents (N7-methyldeoxyguanosine, N7-MedG). DNA was extracted from cervical cytology samples and N7-MedG levels were measured using an immunoslotblot assay. Ninety percentage of the DNA samples were alkylated and N7-MedG levels (mean, 95% CI) in ever-smokers (1.27, 0.90-1.81 micromol/mol dG) were significantly higher than those in nonsmokers (0.42, 0.20-0.91 micromol/mol dG: p = 0.005). N7-MedG adduct levels were significantly correlated with number of cigarettes smoked per day and pack years of cigarette smoking in current smokers. There was no association with N7-MedG levels and cervical intraepithelial neoplasia status, age, parity or contraception use. Our study suggests that cervical DNA contains alkylation damage that can arise from exposure to cigarette smoke.

RESUMO

An assessment of indoor air quality in homes from the greater Houston and Southeast Texas area was sampled over a three-month period to ascertain the potential toxic exposure to molds and mycotoxins. In 2001 Houston experienced widespread flooding due to Tropical Storm Allison. The slow receding waters allowed molds to proliferate to great levels and affected many homes and businesses in and around the Houston area. Source (air) and surface (swab, tape, and bulk) samples were taken in fungal contaminated residences to measure the amounts of airborne and surface contaminants. Indoor airborne counts of fungal spores that were identified to be 80% or more of the outside counts of similar fungal genera were classified as indoor air contaminants. This study identified species of Aspergillus, Penicilliulm, and Cladosporium at levels ranging from 80% to 20 times greater than the corresponding outdoor readings in the greater Southeast Texas area. Aspergillus and Penicillium species are considered potentially toxic to humans at elevated levels due to their ability to produce mycotoxins. Cladosporium is considered nonpathogenic, but can still cause allergenic reactions from hyphal fragments. Surface sampling which is utilized for identification of visible mold contaminants, identified species of Aspergillus. Penicillium, Chaetomium, Cladosporium, and Stachybotrys ranging from 1 to 100 total colony counts (1-100% for tape and bulk noncultured assays) contingent upon the extent of visual contamination. The numerical values from surface sampling were used primarily to identify the degree of visual contamination, as well as, identify any molds that may have been too heavy to become aerosolized.
