Demographic and clinical correlates of depression among older adults with arthritis in Nigeria.

Background: Older adults have a high prevalence of chronic conditions like arthritis with morbidities, especially depression ranging up to 40% - 70%. Therefore, it is important to explore depression in older adults with arthritis. Aim: This study aimed to determine if any demographic and clinical factors are associated with depression in older adults aged ≥ 60 years with arthritis attending a rheumatology clinic. Setting: This is a cross-sectional study conducted over 6 months among 127 older adults on follow-up care in a university teaching hospital in the North-Eastern region of Nigeria. Methods: A clinical proforma with information about the type of arthritis, duration of illness, hospitalisation, use of medications, co-morbidity was utilised for the data collection. The Geriatric Depression Scale (GDS-30), sociodemographic questionnaire and clinical proforma were administered. Data were analysed using Statistical Product and Service Solutions (SPSS) version 26.0 with the level of significance set as 0.05. Results: The mean age (± standard deviation [s.d.]) was 66.6 (± 5.5) years, with males constituting 57.5%. The prevalence of depression was 57.8%. Osteoarthritis 30.2%, while 69.8% had rheumatoid arthritis. Sociodemographic factors associated with depression include age (p = 0.049), marital status (p = 0.001), and level of education (p = 0.001). Duration of illness (p = 0.02), hospitalisation (p = 0.03), and number of medications (p = 0.01) were clinical factors associated with depression score. Conclusion: The prevalence of depression in older people with arthritis is high and was associated with females, the widowed, no formal education; and those with long duration of illness, those using multiple medications, and those with repeated hospitalisation. Contribution: This finding can enhance the suspicion index for depression to establish standard operating procedures, which will help to improve therapeutic practice for caring for the older adult age group.

The Danish lung cancer registry: A nationwide validation study.

BACKGROUND: This study evaluates the validity of the information in the Danish Lung Cancer Registry (DLCR). Since 2000, the DLCR has been a tool for monitoring interventions and outcome of all Danish lung cancer patients with the intent to streamline and improve treatment and survival. The DLCR receives information from the Danish Patient Registries in addition to clinical information from the treating physicians. In the year 2022, more than 50 papers have been published using DLCR as a data source. However, the DLCR has not previously been validated. METHODS: A random sample of 1000 patients diagnosed with non-small cell lung cancer from 2014 to 2016 and recorded in the DLCR were included for validation. Medical records were reviewed and were considered as the "gold standard" to which data listed in the DLCR were compared. RESULTS: Information was retrieved from medical charts for all patients. Agreement on stage at diagnosis was 90.1 % (95 % CI 88.0-91.9) and on date of diagnoses was 93.8 (95 % CI 92.1-93.2). Agreement on smoking status in pack years (+/- 10 pack years) was 91.2 % (95 % CI 88.6-93.2). The positive predictive value of treatment intent was 87.4 (95 % CI 85.1-89.6). CONCLUSION: The data in the DLCR are complete, detailed and accurate. The comparison of data from the DLCR with the medical records revealed overall high validity of the data in the registry.

Alteration of glucose metabolism and expression of glucose transporters in ovarian cancer.

Aerobic glycolysis also known as the Warburg effect, remains a hallmark of various cancers, including ovarian cancer. Cancer cells undergo metabolic changes to sustain their tumorigenic properties and adapt to environmental conditions, such as hypoxia and nutrient starvation. Altered metabolic pathways not only facilitate ovarian cancer cells' survival and proliferation but also endow them to metastasize, develop resistance to chemotherapy, maintain cancer stem cell phenotype, and escape anti-tumor immune responses. Glucose transporters (GLUTs), which play a pivotal role as the rate-limiting step in glycolysis, are frequently overexpressed in a variety of tumors, including ovarian cancer. Multiple oncoproteins can regulate GLUT proteins, promoting tumor proliferation, migration, and metastasis, either dependent or independent of glycolysis. This review examines the alteration of GLUT proteins, particularly GLUT1, in ovarian cancer and its impact on cancer initiation, progression, and resistance to treatment. Additionally, it highlights the role of these proteins as biomarkers for diagnosis and prognosis in ovarian cancer, and delves into novel therapeutic strategies currently under development that target GLUT isoforms.

Multidisciplinary approach in resection of stage IIIA lung cancer with severe aortic stenosis: A case report.

Thoracic surgery in the context of complex multimorbidity and clinical deterioration presents a unique set of challenges when balancing risk and benefit. Advances in anaesthesia, surgical technique, and imaging, have allowed for operative options for patients that were once deemed too high-risk. An effective proactive multi-disciplinary approach is essential for successful outcomes. We report the case of a 65-year-old patient with a background of severe aortic stenosis who underwent lung resection for stage IIIA lung cancer, where pivotal multi-disciplinary team input from the anaesthetic, surgery, critical care and radiology teams, clarified the cause of his clinical deterioration, contributed to decisions over his management and ensured a good clinical outcome.

Evaluation of Three Cytomegalovirus IgG Lateral Flow Assays for Rapid Determination of CMV Serostatus.

Background: Cytomegalovirus (CMV) serostatus is a major determinant of CMV infection, disease risk, and transplant outcomes. Current clinical serology assays are limited by relatively slow turnaround time, design for batched testing, need for trained personnel, and/or specialized equipment. Rapid diagnostic assays in development have a role in emerging settings, such as critically ill patients, but have not been systematically evaluated. Methods: We assessed the performance of 3 rapid lateral flow assays (LFAs) for the detection of CMV immunoglobulin (Ig)G antibodies compared with a reference commercially available CMV IgG enzyme-linked immunosorbent assay in residual serum samples from 200 consecutive adults who underwent clinical CMV serology testing. Samples with discrepant results between the LFA and reference assay were tested by a second reference assay. A subset of serum samples was assessed for interoperator variability. Operating characteristics of the QooLabs LFA were separately assessed in plasma samples. Results: The sensitivity and specificity of the individual LFA assays using serum varied significantly: 86%/83%, 99/93%, and 57/97%, for Healgen, QNow automated reader, and nanoComposix, respectively, compared with the reference assay. Results for the QNow assay were comparable between automated and manual reads. Among a subset of 10 serum samples assessed by 5 individual operators, 44 of 50 (88%) results were concordant. Among 50 plasma samples assessed by the QooLabs LFA, the sensitivity and specificity were 72% and 96%. Conclusions: The ease of performance, rapid turnaround time, and good operating characteristics provide the rationale for further evaluation of the Qoolabs QNow LFA in specialized settings where rapid assessment of CMV serostatus would be advantageous.

EWSR1::ATF1 fusions characterize a group of extra-abdominal epithelioid and round cell mesenchymal neoplasms, phenotypically overlapping with sclerosing epithelioid fibrosarcomas, and intra-abdominal FET::CREB fusion neoplasms.

With the increasing use of next generation sequencing in soft tissue pathology, particularly in neoplasms not fitting any World Health Organization (WHO) category, the spectrum of EWSR1 fusion-associated soft tissue neoplasms has been expanding significantly. Although recurrent EWSR1::ATF1 fusions were initially limited to a triad of mesenchymal neoplasms including clear cell sarcoma of soft tissue, angiomatoid fibrous histiocytoma and malignant gastrointestinal neuroectodermal tumor (MGNET), this family has been expanding. We herein describe 4 unclassified extra-abdominal soft tissue (n = 3) and bone (n = 1) neoplasms displaying epithelioid and round cell morphology and carrying an EWSR1::ATF1 fusion. Affected were 3 males and 1 female aged 20-56 years. All primary tumors were extra-abdominal and deep-seated (chest wall, mediastinum, deltoid, and parapharyngeal soft tissue). Their size ranged 4.4-7.5 cm (median, 6.2). One patient presented with constitutional symptoms. Surgery with (2) or without (1) neo/adjuvant therapy was the treatment. At last follow-up (8-21 months), 2 patients developed progressive disease (1 recurrence; 1 distant metastasis). The immunophenotype of these tumors is potentially misleading with variable expression of EMA (2 of 3), pankeratin (2 of 4), synaptophysin (2 of 3), MUC4 (1 of 3), and ALK (1 of 3). All tumors were negative for S100 and SOX10. These observations point to the existence of heretofore under-recognized group of epithelioid and round cell neoplasms of soft tissue and bone, driven by EWSR1::ATF1 fusions, but distinct from established EWSR1::ATF1-associated soft tissue entities. Their overall morphology and immunophenotype recapitulate that of the emerging EWSR1/FUS::CREB fusion associated intra-abdominal epithelioid/round cell neoplasms. Our cases point to a potentially aggressive clinical behavior. Recognizing this tumor type is mandatory to delineate any inherent biological and/or therapeutic distinctness from other, better-known sarcomas in the differential diagnosis including sclerosing epithelioid fibrosarcoma.

Benign metastasizing fumarate hydratase (FH)-deficient uterine leiomyomas: clinicopathological and molecular study with first documentation of multi-organ metastases.

Leiomyoma is the most prevalent benign tumor of the female reproductive system. Benign metastasizing leiomyoma (BML) is a rare phenomenon that presents at distant sites, typically the lungs, exhibiting histopathological features similar to the primary uterine tumor in the absence of malignancy features in both. Fumarate hydratase-deficient uterine leiomyoma (FH-d UL) is an uncommon subtype among uterine smooth muscle tumors (0.5-2%), showing distinctive histomorphology and FH inactivation. The majority of FH-d ULs are sporadic, caused by somatic FH inactivation, while a minority of cases occur in the context of the hereditary leiomyomatosis and renal cell carcinoma (HLRCC) syndrome caused by germline FH inactivation. Metastasizing FH-d UL has not been well documented and might be under-reported. Here, we present two cases (21- and 34-year-old females) who presented with metastasizing FH-d UL after myomectomy/hysterectomy with histologically proven multiple lung metastases in both, in addition to multi-organ involvement in one case (cervical-thoracic lymph nodes, left kidney, perihepatic region, left zygomatic bone, and soft tissues). Pathological examination confirmed FH-d leiomyomas in the primary/recurrent uterine tumors, multiple lung lesions, and a renal mass. The minimal criteria for diagnosis of leiomyosarcoma were not fulfilled. Genetic testing revealed germline pathogenic FH variants in both cases (c.1256C > T; p.Ser419Leu in Case 1 and c.425A > G; p.Gln142Arg in Case 2). These novel cases highlight a rare but possibly under-recognized presentation of FH-d BML. Our study suggests that FH-d BML cases might be enriched for the HLRCC syndrome.

Outcomes with allogeneic hematopoietic stem cell transplantation in TP53-mutated myelodysplastic syndrome: A systematic review and meta-analysis.

We conducted a systematic review and meta-analysis to evaluate outcomes after allogeneic hematopoietic stem cell transplantation (Allo-HSCT) in TP53-mutated myelodysplastic syndromes (MDS). A literature search was performed on PubMed, Cochrane, Embase, and Clinicaltrials.gov. After screening 626 articles, eight studies were included. Data were extracted following the PRISMA guidelines and analyzed using the meta-package by Schwarzer et al. We analyzed 540 patients. The pooled median 3 (1-5) year overall survival was 21% (95% CI 0.08-0.37, I2=91%, n=540). The pooled relapse rate was 58.9% (95% CI 0.38-0.77, I2=93%, n=487) at a median of 1.75 (1-3) years. The pooled 4-year progression- free survival was 34.8% (95% CI 0.15-0.57, I2=72%, n=105). Outcomes of Allo-HSCT for TP53-mutated MDS patients remain poor, with 21% OS at three years; however, Allo-HSCT confers a survival advantage as compared to non-transplant palliative therapies. Our findings suggest the need to explore novel therapeutic agents in prospective clinical trials.

Codeveloping theories of change for improved community-based violence intervention evaluation.

BACKGROUND: Community-based violence intervention (CVI) programs are considered important strategies for preventing community violence and promoting health and safety. Mixed and inconclusive results from some prior CVI evaluations, as well as our general lack of understanding about the reasons for such varied findings, may be explained in part by misalignment of program theories of change and evaluation measures. Furthermore, most prior evaluations have focused solely on deficit-based outcomes; this narrow focus is inconsistent with the premise of CVI and may fail to capture improvements in health and well-being that are on the hypothesized pathway from intervention to violence reduction. METHODS: This article describes the process and results of codeveloping a theory of change for community-based youth firearm violence intervention and prevention programs in Washington state through a community-researcher partnership. We followed a multistep iterative process, involving (1) CVI program documentation review, (2) individual meetings, and (3) a day-long workshop. RESULTS: The theory of change included six key domains: (1) root causes, (2) promotive factors, (3) activities, (4) intermediate outcomes, (5) longer-term outcomes, and (6) multilevel context (youth/family, staff/organizational, community, and societal). Root causes were social and structural drivers of community violence. Promotive factors were assets and resources among the community, youth/their families, and community organizations that promote health and safety. Activities were supports and services the program provided to youth and their families, staff, and, potentially, the broader community. Intermediate and longer-term outcomes were the changes among youth, their families, staff, and the community that resulted from program activities. Intermediate outcomes may be felt within 6 months to 1 year, and longer-term outcomes may be felt after 1 to 2 years and beyond. CONCLUSION: The theory of change we codeveloped provides a common lens to conceptualize, compare, and evaluate CVI programs in Washington state and may support more rigorous and equity-centered evaluations. LEVEL OF EVIDENCE: Diagnostic Test/Criteria; Level V.

The immunopathological landscape of human pre-TCRα deficiency: From rare to common variants.

We describe humans with rare biallelic loss-of-function PTCRA variants impairing pre-α T cell receptor (pre-TCRα) expression. Low circulating naive αß T cell counts at birth persisted over time, with normal memory αß and high γδ T cell counts. Their TCRα repertoire was biased, which suggests that noncanonical thymic differentiation pathways can rescue αß T cell development. Only a minority of these individuals were sick, with infection, lymphoproliferation, and/or autoimmunity. We also report that 1 in 4000 individuals from the Middle East and South Asia are homozygous for a common hypomorphic PTCRA variant. They had normal circulating naive αß T cell counts but high γδ T cell counts. Although residual pre-TCRα expression drove the differentiation of more αß T cells, autoimmune conditions were more frequent in these patients compared with the general population.

Popular Trend of Electronic Cigarettes and Their Adverse Effects on Oral Health.

Electronic cigarettes were originally promoted as a possible tool to assist individuals in quitting smoking, particularly for those who had been tobacco users for an extended period. Compared with traditional tobacco use, these devices were promoted as a safer option. Over the years, it has been proven that conventional cigarettes adversely affect almost all body systems. Owing to the constantly evolving nature of the products and the difficulties in identifying potential e-cigarette effects in traditional tobacco users including combustible and noncombustible forms, studying the impact of e-cigarette usage on oral health is challenging. Although the existing scientific evidence is limited, it indicates that e-cigarette use may have negative effects on oral health. Moreover, the adoption of vaping among young people has increased globally. There is still a lack of awareness regarding the use of e-cigarettes and their associated health complications, especially in developing countries. We aim to sensitize the readers to the pertinent issue, which has clinical and public health significance.

Congenital Cardiac Catheterization in Low- and Middle-Income Countries: The International Quality Improvement Collaborative Catheterization Registry.

Background: No published data are available on the patient, procedural characteristics, and outcomes of congenital heart disease (CHD) cardiac catheterization performed in low- and middle-income countries (LMICs). Objectives: The objective of this study was to describe procedural characteristics and patient outcomes of CHD cardiac catheterizations in LMICs. Methods: Cases performed between January 2019 and December 2020 from 15 centers in the International Quality Improvement Collaborative Congenital Heart Disease Catheterization Registry (IQIC-CHDCR) data were included. The Procedural Risk in Congenital Cardiac Catheterization (PREDIC3T) classification was used to stratify risk. Outcomes of interest included mortality, severe adverse events (SAEs), and procedural efficacy. Procedural efficacy, based on technical and safety endpoints, was categorized into optimal, adequate, and inadequate for 5 common interventional procedures. Results: There were 3,287 cases, of which 60% (n = 1,973) were interventional cases. Most of the cases (66%) were in patients between the ages of 1 to 18 years with a median patient age of 4 years. PREDIC3T risk class 1 and 2 were most common in 37% and 38% of cases, respectively. SAEs occurred in 2.8% while the death was reported within <72 hours post catheterization 1%. The majority of device implantation procedures patent ductus arteriosus (67%) and atrial septal defect (60%) had optimal procedure efficacy outcomes. Conclusions: This study demonstrates that congenital cardiac catheterization is safely performed in LMICs. Future work addressing predictors of SAEs and adverse procedural outcomes may help future quality improvement initiatives.

Evaluating Procedural Performance: A Composite Outcome for Aortic and Pulmonary Valvuloplasty in Congenital Cardiac Catheterization.

Background: Safety events and technical success (TS) have been previously reported for aortic and pulmonary valvuloplasty, but a composite performance measure as a novel, patient-centered strategy has neither been developed nor been studied. This study aims to refine a procedural performance (PP) variable, a composite of TS and procedural safety, for isolated, standard-risk aortic and pulmonary valvuloplasty. Methods: A multicenter review was performed using data from the Congenital Cardiac Catheterization Project on Outcomes registry. Data were collected for all cases of isolated balloon aortic and pulmonary valvuloplasty from 2014 through 2017. Patients were excluded if they were aged <1 month, were inpatient at the time of the procedure, or had significant comorbidities, such as Williams or Noonan syndrome. Criteria for TS were developed and categorized (optimal, satisfactory, and unsatisfactory) by expert consensus based on previous outcome research. Adverse events (AE) were categorized by severity (level 1-5) using established criteria. Level 4 and 5 severity AE were considered high-severity AE. Using criteria of TS and AE severity, PP was divided into 3 composite outcome classes. Factors correlating with class III (suboptimal) PP were analyzed. Results: There were 169 cases of aortic and 270 cases of pulmonary valvuloplasty in the cohorts. In the aortic valvuloplasty cohort, a suboptimal PP (class III) occurred in 14% of cases, mostly due to high-severity AE (7%). No significant correlation between patient or case characteristics and PP was demonstrated. In the pulmonary valvuloplasty cohort, class III PP occurred in 9% of cases, predominantly due to residual valve gradient, which correlated with lower weight (P = .02). Conclusions: We designed a composite variable of PP consisting of TS and safety as a comprehensive measure of outcome. Incorporating both TS and AE may better reflect patient outcome than each metric measured separately. PP indices may identify areas for further investigation and quality improvement.

Para além dos retratos comuns sobre a condição de refúgio e de migração: narrativas de mulheres palestinas sobre seu protagonismo no Brasil / Beyond the common traits on the condition of refuge and migration: narratives of palestinian women about their activism in Brazil / Más allá de los retratos comunes sobre la condición de refugio y migración: narrativas de mujeres palestinas sobre su activismo en Brasil

Este artigo versa a respeito de processos de superação das situações de refúgio e migração. Partimos da constatação de que ambas as situações são caracterizadas, em geral, pela vulnerabilidade, haja visto a exposição das pessoas envolvidas a situações limites de sobrevivência. Porém, demonstrando um lado menos conhecido deste contexto, pretendemos dar visibilidade e voz a exemplos de superação e de protagonismo feminino árabe-palestino destas situações, através dos relatos de experiências de duas mulheres de origem palestina, que se refugiaram no Brasil e atualmente auxiliam refugiados/as que aqui chegam. Como metodologia utilizamos pesquisa bibliográfica e entrevistas estruturadas, cujas narrativas iremos interpretar com base nos depoimentos. Os relatos corroboram a necessidade de um olhar longitudinal sobre as implicações dos processos de migração e de refúgio onde se manifesta a capacidade de resiliência e superação de mulheres que vivenciaram tais processos e a despeito de seu estado de vulnerabilidade, apontam que os/as principais apoiadores/as das ações são pessoas e entidades civis, haja vista o atual descaso do poder público para com estes projetos.

This article deals with processes of overcoming refuge and migration situations. We start from the observation that both situations are characterized, in general, by vulnerability, having seen the exposure of the people involved to situations of survival limits. However, by demonstrating a lesser known side of this context, we intend to give visibility and voice to examples of overcoming and female Arab-Palestinian protagonist of these situations, through the reports of experiences of two women of Palestinian origin, who took refuge in Brazil and currently assist refugees. / the ones that arrive here. As methodology we use bibliographic research and structured interviews, whose narratives we will interpret based on the statements. The reports corroborate the need for a longitudinal look at the implications of migration and refuge processes in which the resilience and overcoming capacity of women who have experienced such processes is manifested and despite their state of vulnerability, point out that the main supporters the actions are people and civil entities, given the current disregard of the public power towards these projects.
