Recurrent choriocarcinoma complicated with leprosy during chemotherapy: A case report and literature review.

RATIONALE: The global prevalence of leprosy has decreased substantially, and cases of leprosy infection are extremely rare in China. In this report, we present a case of recurrent choriocarcinoma complicated by leprosy infection during chemotherapy. PATIENT CONCERNS: A 24-year-old Chinese woman (gravida 3, para 2) presented to a local hospital with vaginal bleeding. Her medical history included a previous diagnosis of hydatidiform mole. DIAGNOSES, INTERVENTIONS AND OUTCOMES: The patient was diagnosed with choriocarcinoma and received chemotherapy in 6 cycles. Shortly after the initial treatment was completed, the disease recurred twice with resistance to multiple chemotherapeutic agents. In her second recurrence of choriocarcinoma, she was diagnosed with leprosy with many cutaneous nodules throughout her entire body. The patient was administered chemical treatment for leprosy with the multidrug therapy regimen after being diagnosed. To prevent exacerbating the infection, no immunotherapy was utilized to treat cancer, and the infection was well-controlled at the conclusion of anticancer therapy. LESSONS: Because of immunological reduction, cancer patients are susceptible to a variety of infections. For patients with cancer, prevention and early detection of rare infectious diseases should receive special attention. Immunotherapy must be used with caution when treating patients with cancer and infections.

A comparative evaluation of aluminum chloride hexahydrate gel iontophoresis versus tap water iontophoresis in people with primary palmar hyperhidrosis: A randomised clinical trial.

Background Primary palmar hyperhidrosis causes a lot of problems for patients and negatively affects their quality of life. Currently, iontophoresis with tap water and aluminum chloride hexahydrate is used for primary palmar hyperhidrosis. Yet, little evidence exists about iontophoresis with aluminum chloride hexahydrate in the form of gel. This study investigated the effect of aluminum chloride hexahydrate gel iontophoresis compared to tap water iontophoresis on primary palmar hyperhidrosis. Methods In this randomised controlled trial study, 32 patients with primary palmar hyperhidrosis were divided randomly into two groups (n = 16). Participants received 7 sessions of iontophoresis with aluminum chloride hexahydrate gel or tap water every other day on the dominant hand. The sweating rate was measured by gravimetry and iodine-starch tests before and after the last treatment session. Results Following the iontophoresis, the rate of sweating in both hands in the two groups was significantly reduced (P < 0.001). However, the sweating rate in the treated hand and the non-treated hand showed no significant difference. There was no significant difference observed in sweating rate reduction between both groups over time, but the larger effect size values observed in the aluminum chloride hexahydrate gel iontophoresis group may suggest the superiority of this gel over tap water in reducing the rate of sweating. Limitations Further investigations with longer follow-up are needed to confirm the hypothesis regarding the effectiveness of aluminum chloride hexahydrate gel iontophoresis over other types of iontophoresis. In addition, contraindications of iontophoresis such as pregnancy, pacemakers, and epilepsy should be considered. Conclusion The present study provides preliminary evidence suggesting that aluminum chloride hexahydrate gel iontophoresis is an effective alternative treatment to decrease sweating rate in extended areas with fewer side effects in patients with primary palmar hyperhidrosis.

Educação e trabalho na saúde sob participação social organizada e disseminada: a acumulação das conferências livres nacionais 2022-2023 / Education and work in health under organized and disseminated social participation: the accumulation of national free conferences 2022-2023

A coletânea "Educação e trabalho na saúde sob participação social organizada e disseminada: a acumulação das conferências livres nacionais 2022 ­ 2023", reunida por Maria Luiza Jaeger, Ricardo Burg Ceccim e Priscila Viégas Barreto de Oliveira, é uma obra decorrente do cotejamento de seis conferências livres nacionais, realizadas entre final de 2022 e início de 2023, como parte da construção da 17ª Conferência Nacional de Saúde, das quais participou a Associação Científica Rede Unida […]. O foco da entidade é a Educação e Trabalho na Saúde, fazendo parte da comunidade de entidades/sociedades científicas com forte presença junto ao Conselho Nacional de Saúde, inclusive integrando várias de suas Comissões, em especial a Comissão Intersetorial de Recursos Humanos e Relações de Trabalho. A entidade também integra o Fórum de Entidades Nacionais de Trabalhadores da Área da Saúde, instância que congrega Conselhos, Federações e Associações presentes no campo da saúde. Considerada essa personalidade institucional, a Rede Unida integrou conferências nacionais livres onde o tema da Educação e Trabalho na Saúde formaram tópicos estratégicos ao debate dos rumos no Sistema Único de Saúde. […] A obra representa um esforço de memória e apoio ao exercício do controle social em saúde nos termos da Constituição Federal relativamente ao setor da saúde e especialmente no tocante à Lei Federal 8.142, de 28 de dezembro de 1990. A anotação "participação social organizada e disseminada" ao título da coletânea diz respeito à congregação de participantes país afora de modo orquestrado pelo Conselho Nacional de Saúde em um dispositivo inovador à democracia: a chancela às estratégias autogeridas, capazes de acumular engajamento, reflexão e contribuição cidadã às políticas públicas de saúde. Essa nova realidade certamente se tornará mais um patrimônio brasileiro aos sistemas de saúde. A coletânea inicia a acaba no escopo da Educação e Trabalho na Saúde, este é seu propósito: recolher da participação social organizada e disseminada as contribuições de um campo particular pouco reconhecido como campo nas áreas de Ensino da Saúde e da Saúde Coletiva. Contudo, um campo germinativo, potente e aglutinador à ciência, à docência, à intervenção e à inovação.

MiR-1290: a potential therapeutic target for regenerative medicine or diagnosis and treatment of non-malignant diseases.

MicroRNAs are a set of small non-coding RNAs that could change gene expression with post-transcriptional regulation. MiRNAs have a significant role in regulating molecular signaling pathways and innate and adaptive immune system activity. Moreover, miRNAs can be utilized as a powerful instrument for tissue engineers and regenerative medicine by altering the expression of genes and growth factors. MiR-1290, which was first discovered in human embryonic stem cells, is one of those miRNAs that play an essential role in developing the fetal nervous system. This review aims to discuss current findings on miR-1290 in different human pathologies and determine whether manipulation of miR-1290 could be considered a possible therapeutic strategy to treat different non-malignant diseases. The results of these studies suggest that the regulation of miR-1290 may be helpful in the treatment of some bacterial (leprosy) and viral infections (HIV, influenza A, and Borna disease virus). Also, adjusting the expression of miR-1290 in non-infectious diseases such as celiac disease, necrotizing enterocolitis, polycystic ovary syndrome, pulmonary fibrosis, ankylosing spondylitis, muscle atrophy, sarcopenia, and ischemic heart disease can help to treat these diseases better. In addition to acting as a biomarker for the diagnosis of non-malignant diseases (such as NAFLD, fetal growth, preeclampsia, down syndrome, chronic rhinosinusitis, and oral lichen planus), the miR-1290 can also be used as a valuable instrument in tissue engineering and reconstructive medicine. Consequently, it is suggested that the regulation of miR-1290 could be considered a possible therapeutic target in the treatment of non-malignant diseases in the future.

A Pandemia e o Trabalho em Saúde: vozes do cotidiano / The Pandemic and Health Work: everyday voices

Com esta obra buscamos apresentar ao leitor reflexões sobre a COVID -19 e seus impactos no mercado de trabalho, especialmente num contexto de desigualdade social, onde muitos trabalhadores de ocupações essenciais ou não precisaram se expor ao vírus para manter a sua sobrevivência e a de sua família. Ao final das análises, pontuamos a necessidade proteção dos trabalhadores em tempos de Covid, orientações para os serviços e gestores de saúde, com a finalidade de desencadear a discussão sobre a invisibilidade de muitos trabalhadores que ficaram desprotegidos pelas políticas sociais brasileiras durante a pandemia de COVID-19. Com esse conjunto de textos, esperamos ampliar a compreensão sobre os efeitos da pandemia nos trabalhadores e trabalhadoras e, ao mesmo tempo, ativar o pensamento para iniciativas que são visibilizadas pelas autoras e autores. Ou seja, mais do que buscar aprendizagem com a experiência trágica da pandemia, pretendemos também construir novas manhãs para o trabalho na saúde. Objetivo oportuno, já que estamos diante da preparação da 17ª Conferência Nacional de Saúde, que terá o tema "Garantir Direitos e Defender o SUS, a Vida e a Democracia ­ Amanhã Vai Ser Outro Dia". Acreditamos que a pandemia será memória, aprendizagem e mobilização para retomarmos a agenda da proteção do trabalho, ampliarmos a compreensão de que o trabalho é direito humano e não dependência do capital, expandirmos iniciativas de políticas de proteção da vida e avançarmos no processo civilizatório que é necessário, como bem nos lembrou Sérgio Arouca na abertura da 8ª Conferência Nacional de Saúde, para que o SUS seja possível. Por fim, nossa homenagem às trabalhadoras e trabalhadores que, asfixiados pela pandemia e órfãos da ação governamental responsável, tiveram suas vidas tomadas nesses anos. Especialmente àqueles que foram vitimados desde sua inserção no trabalho em saúde. Aliás, não somente aos que partiram, também a todas as pessoas que se ocupam do trabalho em saúde nos sistemas, redes e serviços de saúde, mas também nos pontos de atenção nos territórios, com trabalhos informais e, muitas vezes, invisíveis. A vocês, nossas palmas, nosso reconhecimento e nossa luta para novas manhãs!

Vozes, olhares e sentidos da Participação Social no SUS / Voices, looks and senses of Social Participation in the SUS

Olhando para a trajetória histórica compreende-se melhor a relação entre "Democracia e Saúde" estabelecida para 16ª Conferência Nacional de Saúde realizada em 2019, pois a luta pelo direito à saúde e a implementação do SUS está vinculada a busca pela redemocratização e a ampliação dos direitos sociais no Brasil. As instâncias do controle social se consolidaram no decorrer das três décadas de sua existência, os movimentos sociais, bem como, as mais diversas organizações da sociedade civil, ocuparam estes espaços e buscaram transformá-los numa arena democrática de defesa da sua concepção de saúde, de política pública, de Estado, de desenvolvimento e de direitos humanos.

Active case detection and treatment of malaria in pregnancy using LAMP technology (LAMPREG): a pragmatic randomised diagnostic outcomes trial-study protocol.

INTRODUCTION: Malaria is one of the major public health problems in sub-Saharan Africa. It contributes significantly to maternal and fetal morbidity and mortality in affected countries. This study aims to evaluate the impact of enhanced case detection using molecular testing called loop-mediated isothermal amplification (LAMP) on birth outcomes in a prospective study design. METHODS AND ANALYSIS: A pragmatic randomised diagnostic outcomes trial will be conducted in several health institutes in different Ethiopian regions. Women (n=2583) in their first and second trimesters of pregnancy will be included in the study and individually randomised to the standard of care or enhanced case detection arms, and followed until delivery. Enrolment will encompass the malaria peak transmission seasons. In the standard of care arm, a venous blood sample will be collected for malaria diagnosis only in symptomatic patients. In contrast, in the intervention arm, mothers will be tested by a commercially available Conformité Européene (CE)-approved LAMP malaria test, microscopy and rapid diagnostic test for malaria regardless of their symptoms at each antenatal care visit. The primary outcome of the study is to measure birth weight. ETHICS AND DISSEMINATION: The study was approved by the following ethical research boards: Armauer Hansen Research Institute/ALERT Ethics Review Committee (FORM AF-10-015.1, Protocol number PO/05/20), the Ethiopia Ministry of Science and Higher Education National Research Ethics Review Committee (approval SRA/11.7/7115/20), the Ethiopia Food and Drug Administration (approval 02/25/33/I), UCalgary Conjoint Health Research Ethics Board (REB21-0234). The study results will be shared with the institutions and stakeholders such as the Ethiopia Ministry of Health, the Foundation for Innovative Diagnostics, WHO's Multilateral initiative on Malaria - Tropical Diseases Research (TDR-MIM), Roll Back Malaria and the Malaria in Pregnancy Consortium. The study results will also be published in peer-reviewed journals and presented at international conferences. TRIAL REGISTRATION NUMBER: NCT03754322.

1ª Conferência Nacional de Vigilância em Saúde: processo ascendente e participativo / 1st National Health Surveillance Conference: bottom-up and participatory process

Este livro foi organizado e produzido para documentar e expandir o acesso às deliberações da 1ª Conferência Nacional de Vigilância em Saúde, com a expectativa de que se tornem vivas no cotidiano de todas as pessoas em todo o território brasileiro. Afinal, sistematizar o trabalho que se realiza pelo controle social no SUS é fundamental, inclusive para ocupar a condição de relevância pública que a Constituição Brasileira de 1988 atribuiu às ações e serviços de saúde. Tornar esse trabalho visível e reconhecê-lo nessa condição tem a dupla finalidade de fortalecer o SUS como política de saúde do estado brasileiro, conquistada pela população em esforço e luta, e de consolidar a relação entre a saúde e a democracia, aqui expressa pela designação das necessidades nos diferentes territórios e de forma ascendente, materializando a diretriz que embasa a institucionalidade do aparelho estatal na definição constitucional de que a saúde é bem de todos e que os governos devem agir para preservá-la e fortalecê-la.

Use of healthcare services during the COVID-19 pandemic in urban Ethiopia: evidence from retrospective health facility survey data.

OBJECTIVES: In recent years, Ethiopia has made enormous strides in enhancing access to healthcare, especially, maternal and child healthcare. With the onset and spread of COVID-19, the attention of the healthcare system has pivoted to handling the disease, potentially at the cost of other healthcare needs. This paper explores whether this shift has come at the cost of non-Covid related healthcare, especially the use of maternal and child health (MCH) services. SETTING: Data covering a 24-month period are drawn from 59 health centres and 29 public hospitals located in urban Ethiopia. PRIMARY AND SECONDARY OUTCOMES MEASURES: The primary outcome measures are the use of MCH services including family planning, antenatal and postnatal care, abortion care, delivery and immunisation. The secondary outcome measures are the use of health services by adults including antiretroviral therapy (ART), tuberculosis (TB) and leprosy and dental services RESULTS: There is a sharp reduction in the use of both inpatient (20%-27%, p<0.001) and outpatient (27%-34%, p<0.001) care, particularly in Addis Ababa, which has been most acutely affected by the virus. This decline does not come at the cost of MCH services. The use of several MCH components (skilled birth attendant deliveries, immunisation, postnatal care) remains unaffected throughout the period while others (family planning services, antenatal care) experience a decline (8%-17%) in the immediate aftermath but recover soon after. CONCLUSION: Concerns about the crowding out of MCH services due to the focus on COVID-19 are unfounded. Proactive measures taken by the government and healthcare facilities to ring-fence the use of essential healthcare services have mitigated service disruptions. The results underline the resilience and agility displayed by one of the world's most resource-constrained healthcare systems. Further research on the approaches used to mitigate disruptions is needed.

Informe técnico N. 001/22 - Hanseníase: orientações para a prescrição e dispensação do medicamento talidomida / Technical report N. 001/22 - Leprosy: guidelines for prescribing and dispensing thalidomide drug

Comparative analysis of the use and control of thalidomide in Brazil and different countries: is it possible to say there is safety?

INTRODUCTION: One of the biggest drug disasters in history has not prevented thalidomide from being used to treat various clinical conditions. Currently, Brazil has a worrying scenario: high consumption of the drug and, cases of pregnant women using thalidomide, even after adopting restrictive legislation. AREAS COVERED: This review of the literature and legislation sought to comparatively analyze the monitoring of thalidomide use in Brazil and other countries that use this drug. Finally, we discuss the differences between the countries. EXPERT OPINION: This analysis allows us to think beyond the safe use of thalidomide, but the safety provided by any type of monitoring system. It seems that out-patients that use unsafe drugs are exposed to some degree of risk. To improve safety, more extensive improvements are needed than monitoring systems related to the use of thalidomide. Its safe use depends on a drastic reduction in the incidence of leprosy and Erythema Nodosum Leprosum in the world; investment in research and development of safe and effective therapeutic alternatives to thalidomide; improvement of health systems and their health surveillance systems, particularly in primary health care; awareness of health professionals and patients for greater responsibility in the use of medicines, especially thalidomide.

Assessing the causal effects of long-term exposure to PM2.5 during pregnancy on cognitive function in the adolescence: Evidence from a nationwide cohort in China.

The effects of air pollution on adolescents need further consideration. Although there is evidence that maternal exposure to air pollution may affect the cognitive function of offspring, relevant studies remain limited and inconsistent, with a lack of studies assessing the causal effects and evidence from developing countries. Using data from Chinese Family Panel Studies, a representative Chinese nationwide cohort study, OLS combined with instrumental variable + two-stage least square (IV+2SLS) was used to explore the causal effects of exposure to PM2.5 concentrations during pregnancy on the cognitive function of offspring when they become adolescents. After detailed argumentation and multiple testing, Planetary Boundary Layer Height (PBLH) and Surface Pressure (SP) were selected as the instrumental variables for this study. One thousand five hundred fifty-five adolescents participated in this study, with a mean age of 13.3 years (sd = 2.3). There were 706 females (45.4%), the mean maternal PM2.5 exposure concentration was 64.9 µg/m3, and recorded a mean cognitive function score of 38.1 (sd = 9.4). The OLS results found that maternal exposure to air pollution increased cognitive function in offspring adolescents, corroborating the presence of endogeneity. Multi-domain knowledge, the results of the weak instrumental variable assessments of F-tests (F = 237 > 10) and Stock-yogo tests (minimum eigenvalue statistic = 153.16 > 16.38), and the results of the Hansen J overidentification test (p > 0.05) verified the plausibility and validity of the instrumental variables. The IV+2SLS results, following causal modeling, showed that PM2.5 exposure during pregnancy impairs the cognitive ability of offspring adolescents (ß = -0.040, p < 0.05). Robustness tests also validated the results. This study provides important policy implications for developing countries on protecting their adolescents and reminds parents that the protection of adolescents from air pollution should begin from conception.

Clinicopathological Study of Chronic Kidney Disease of Unknown Etiology in Odisha.

INTRODUCTION: Chronic kidney disease (CKD) is emerging as a serious health problem in Odisha, India. A new form of severe CKD affecting adults, not due to traditional risk factors like diabetes, hypertension, glomerulonephritis, has been reported in Sri Lanka, Central America, and Egypt in the last two decades. This has been named CKD of unknown origin (CKDu), and it is fatal due to late recognition and rapid disease progression. The aim of the study was to elucidate the association between different sociodemographic, and biochemical parameters with renal morphology in CKD of unknown origin patients. METHODS: A cross-sectional study was conducted on 124 consecutive patients with CKD from the period January 2018 to December 2018. Patients in the age group 18-60 years who met clinical criteria for CKD were included. Participants answered a questionnaire. After the necessary history, clinical evaluation, and blood and urine analyses, a kidney biopsy was undertaken. Kidney biopsy was feasible in 51 patients as the rest 61 patients had shrunken kidneys and 12 patients did not give consent. Patients with diabetes mellitus (DM), hypertension, glomerulonephritis, polycystic kidney disease, obstructive kidney disease or any other congenital diseases, snakebite, pregnancy, malignancy, gout, primary hyperparathyroidism, infectious diseases like human immunodeficiency virus (HIV), TB, Hepatitis B and C, malaria, syphilis, leprosy and coagulopathies were excluded. Among the 51 patients, 23 had CKDu, 25 had chronic glomerulonephritis and three biopsies were inconclusive. RESULTS: The mean age of CKDu patients was 36.78 ± 9.85 years. Males (73.9%) were predominantly affected. A family history of CKD was seen in 82.6% of CKDu cases. Hyponatremia and hypokalemia were predominant biochemical abnormalities in our CKDu cases. Binary logistic regression showed rural residence, family history of CKD, exposure to smoke from burning coal, charcoal, or biomass fuels, low socioeconomic status, and low body mass index were strongly associated with CKDu. There was an increased risk of developing CKDu in persons with a family history of CKD [p = 0.003, odds ratio (OR)- 17.58], persons exposed to smoke from burning coal, charcoal or biomass fuels (p = 0.003, OR- 32.4), and patients with low socio-economic status (p = 0.001, OR- 15.87). Interstitial fibrosis (IF), interstitial inflammation with mononuclear infiltration, tubular atrophy (TA), and global glomerulosclerosis (GS) were pertinent histopathological findings in our study. CONCLUSION: There is no strong evidence for a single cause for CKDu, and multiple environmental, occupational and social factors are probably involved. We need to design consistent and comparative multisite studies to identify etiologies of CKDu, across high-risk populations that may help elucidate the importance of region-specific vs global risk factors.

Implementation of a Pregnancy Prevention Programme (PPP) with a Controlled Distribution System (CDS) for the Generic Teratogenic Phthalimides Thalidomide, Lenalidomide and Pomalidomide.

Thalidomide (α-phthalimidoglutaride) was marketed in the 1950s and early 1960s; it was promoted as a sedative-hypnotic agent with minimal hangover. It was available in some countries as an over-the-counter medicine. Publications reporting profound teratogenic effects with thalidomide brought about major revisions to the monitoring of the safety of medicines. As a consequence of previously unrecognised teratogenic effects, it has been estimated that over 12,000 children were born with a range of defects and disabilities, including severe congenital anomalies. Notably, it has been hypothesised that around 40% of babies with thalidomide-induced malformations born during the 1950s and 1960s died in the neonatal period. The commonest causes of death were atresia of the small bowel, cardiac or renal malformations. Nevertheless, phocomelia (as a typical manifestation of thalidomide´s teratogenic effects) has been reported once again after thalidomide was approved for use in areas where leprosy is endemic. As a result, thalidomide embryopathy remains an important topic in countries such as Brazil. Nowadays thalidomide is approved around the world for the treatment of a wide range of conditions, including leprosy, Crohn's disease, multiple myeloma, and certain malignant solid tumours. Second-generation immunmodulatory drugs including lenalidomide and pomalidomide have received approval for use in the management of various forms of neoplastic disease. Based on clinical experience with thalidomide and its derivatives, learnings have been transferred to further research on a subset of substituted phthalimides each of which has a high risk of causing teratogenic effects. This group of phthalimides is classified within regulatory science as human teratogens. In order to gain approval, a Pregnancy Prevention Programme (PPP), along with a Controlled Distribution System (CDS) is required. The challenges of PPPs in particular for a generic manufacturer have been described, including Raising of awareness, and education; Special aspects of data collection and evaluation; Ethically and socially relevant aspects, and Utilising existing information technology and infrastructure. This paper highlights the risks of unplanned pregnancies, provides information on the regulatory background, and regulatory expectations. Our aim is to provide insights and practical learnings that have impacted operational risk management with the teratogenic phthalimides. Opportunities are presented that may support the implementation of harmonised approaches for PPP and CDS using existing IT-systems across countries and companies.

A drug repositioning success: The repositioned therapeutic applications and mechanisms of action of thalidomide.

BACKGROUND: Thalidomide is the most teratogenic human medicine ever marketed and was associated with birth defects in approximately 10,000 children in the 1960s. The pharmacological effects of thalidomide are attributed to its anti-angiogenic, anti-inflammatory and modulatory effect on cytokines principally tumor necrosis factor-α, while the teratogenic effects are linked to two molecular targets, namely cereblon and tubulin. Teratogenicity is the gravest adverse effect of thalidomide depending on the dose and time of exposure. Nonetheless, with System for Thalidomide Education and Prescribing Safety program, the possibility of teratogenicity can be completely avoided. The sensitive period during pregnancy for thalidomide teratogenicity in humans is approximately 20-34 days after fertilization. METHODS: Relevant articles were identified from Google scholar and PubMed (MEDLINE) using different search strategies. CONCLUSION: Clinical trials showed that thalidomide has been found effective in the treatment of advanced renal cancer, esophageal cancer, chemotherapy refractory endometrial cancer and pancreatic cancer, which can suggest its future therapeutic potential in cancer treatment. Thalidomide is also used in the treatment of inflammatory skin disorders and has shown promising effect in the treatment of autoimmune disorders and inflammatory bowel disease. Despite thalidomide being a renowned teratogen and neurotoxin, it has been successfully repositioned and FDA approved for the treatment of erythema nodosum leprosum and multiple myeloma under strict control.
