RESUMO

Contextualização: A displasia broncopulmonar é uma das principais causas de enfermidade respiratória crônica na infância, levando a hospitalizações frequentes e prolongadas e com altos índices de mortalidade, alterações do crescimento pôndero-estatural e desenvolvimento neuropsicomotor. Tamanho impacto justifica o grande investimento nas pesquisas para identificar suas causas e buscar alternativas para prevenção e tratamento. Objetivos: Avaliar a efetividade das intervenções para prevenção de displasia broncopulmonar em recém-nascidos prematuros com ventilação mecânica invasiva. Métodos: Trata-se de overview de revisões sistemáticas realizadas pela Colaboração Cochrane. Procedeu-se à busca na Cochrane Library (2022), utilizando os termos "neonatal prematurity" e "bronchopulmonary dysplasia". Foram incluídos todos os ensaios clínicos randomizados. O desfecho primário de análise foi a redução de morbimortalidade. Resultados: A estratégia de busca recuperou um total de 47 revisões sistemáticas. Oito foram incluídas, totalizando 94 ensaios clínicos randomizados e 10.511 participantes. Discussão: Os estudos demonstram efetividade de corticosteroides, mas é necessário cautela na dosagem e no momento correto para sua administração. O uso de surfactante sintético pode trazer benefícios respiratórios, mas requer novos estudos. Não se justifica o uso de pentoxifilina. Conclusão: A displasia broncopulmonar tornou-se um grande desafio para o neonatologista e as revisões sistemáticas Cochrane sugerem que a corticoterapia pode ser efetiva na prevenção dessa condição, embora novos estudos sejam recomendados para estabelecer dosagem ideal e melhor momento para a terapêutica.

RESUMO

A prevalência das disfunções sexuais é alta na população geral. A capacidade de regular as experiências emocionais facilita o relacionamento mais adaptado aos estados internos e às condições ambientais. A prática da atenção plena promove atenção à experiência do momento presente ­ com curiosidade, abertura, aceitação, não reatividade e não julgamento ­ e tem se mostrado eficaz para melhorar muitas condições biopsicossociais, sendo utilizada em ambientes de saúde, escolas e locais de trabalho. O objetivo é apresentar atualizações na abordagem das dificuldades sexuais por meio do desenvolvimento da atenção plena. Entre outras recomendações, o treinamento para descentralizar a atenção, o desenvolvimento de habilidades para perceber pensamentos e sentimentos como estados mentais, não necessariamente reais, além de promover aceitação, compaixão e melhor gestão de pensamentos intrusivos e ruminativos são alguns pontos positivos da prática da atenção plena como única abordagem ou associada a outras. É apresentado um protocolo com grupo terapêutico para desenvolvimento da atenção plena para casais, em que o parceiro é sobrevivente do câncer de próstata. Segue uma proposta terapêutica com oito módulos desenvolvida em formato presencial e adaptada para a plataforma virtual. Os módulos são: definições e causas da disfunção sexual; conscientização crescente das sensações físicas; exploração do corpo e julgamentos sobre ele; consciência de pensamentos e crenças sexuais; trabalho com aversão e autotoque; consciência das sensações sexuais; foco sensorial com o parceiro; manutenção (e aumento) dos ganhos. Essa prática desenvolvida online abriu um campo importante para beneficiar portadores de disfunção sexual com dificuldade para buscar outras modalidades de intervenção.

RESUMO

Contexto: A mastocitose ocorre devido a uma proliferação neoplásica e clonal de mastócitos que se acumulam em um ou mais sistemas de órgãos. A doença é heterogênea, com manifestações que vão desde lesões cutâneas que podem regredir espontaneamente até neoplasias altamente agressivas associadas à falência de múltiplos órgãos e baixa sobrevida. Não há relatos na literatura de sua associação com líquen plano. Descrição do caso: Relatamos o caso de uma paciente com diagnóstico de mastocitose sistêmica agressiva que apresentou durante o acompanhamento quadro compatível com líquen plano. Discussão: O diagnóstico da mastocitose sistêmica é baseado em critérios que foram refinados recentemente. O tratamento classicamente envolve bloqueio de mediadores de mastócitos e terapia citorredutora para variantes avançadas da doença. Novas drogas como a midostaurina e o avapritinibe são promissoras. Conclusões: Mesmo não fazendo parte da rotina do dermatologista, a mastocitose sistêmica deve ser uma doença lembrada pelo acometimento da pele e potencial gravidade do quadro.

RESUMO

Contexto e Objetivo: Ingestão de água com espessante diminui a aspiração para vias aéreas em pacientes com disfagia orofaríngea, entretanto pode causar dificuldade na ingestão. Nosso objetivo foi avaliar, em pessoas saudáveis, a influência da obesidade, idade e sexo na ingestão de água espessada. Desenho e local: Estudo transversal realizado em amostra de conveniência na Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo. Método: Ingestão de água sem e com espessante foi avaliada em 75 indivíduos saudáveis (42 mulheres) com idades entre 18 e 62 anos, pelo teste de ingestão de água, com os voluntários ingerindo 100 ml de água na temperatura ambiente, sem e com 2,4 g de espessante alimentar. Foram medidos o tempo para ingerir todo o volume, o número de deglutições, e calculados o fluxo de ingestão e o volume em cada deglutição, com os voluntários indicando a sensação e a dificuldade na ingestão. Resultados: Com espessante, o fluxo de ingestão e o volume em cada deglutição foram menores, e houve maior dificuldade e pior sensação durante a ingestão. Obesidade e idade não influenciaram a ingestão. As mulheres tiveram menor fluxo de ingestão que os homens. Discussão: A utilização de água espessada em pacientes com disfagia pode ter dificuldades que comprometem a hidratação. Alteração do sabor e temperatura do líquido podem facilitar a ingestão. Conclusão: A ingestão de água em pessoas saudáveis tem influência da consistência e do sexo dos indivíduos, sem influência de idade ou obesidade.

RESUMO

BACKGROUND: Autophagy is a highly conserved cellular proteolytic process that can interact with innate immune signaling pathways to affect the growth of tumor cells. However, the regulatory mechanism of autophagy in the tumor microenvironment, drug sensitivity, and immunotherapy is still unclear. METHODS: Based on the prognostic autophagy-related genes, we used the unsupervised clustering method to divide 866 ovarian cancer samples into two regulatory patterns. According to the phenotypic regulation pattern formed by the differential gene between the two regulation patterns, a risk model was constructed to quantify patients with ovarian cancer. Then, we systematically analyzed the relationship between the risk model and immune cell infiltration, immunotherapeutic response, and drug sensitivity. RESULTS: Based on autophagy-related genes, we found two autophagy regulation patterns, and confirmed that there were differences in prognosis and immune cell infiltration between them. Subsequently, we constructed a risk model, which was divided into a high-risk group and a low-risk group. We found that the high-risk group had a worse prognosis, and the main infiltrating immune cells were adaptive immune cells, such as Th2 cells, Tgd cells, eosinophils cells, and lymph vessels cells. The low-risk group had a better prognosis, and the most infiltrated immune cells were innate immune cells, such as aDC cells, NK CD56dim cells, and NK CD56bright cells. Furthermore, we found that the risk model could predict chemosensitivity and immunotherapy response, suggesting that the risk model may help to formulate personalized treatment plans for patients. CONCLUSIONS: Our study comprehensively analyzed the prognostic potential of autophagy-related risk models in ovarian cancer and determined their clinical guiding role in targeted therapy and immunotherapy.

RESUMO

BACKGROUND: Primary cerebral epithelioid angiosarcoma (PCEA) is a rare malignant tumor of the central nervous system. To the best of our knowledge, only three cases have been reported in the English language literature thus far. CASE PRESENTATION: Here, we report a fourth case in a 73-year-old man admitted for headache. Radiological examination revealed a mass in the right occipital lobe, which was removed by right occipital craniotomy. Histopathological examination revealed epithelioid angiosarcoma. The patient received radiotherapy after resection but survived for only nine months due to recurrence of the tumor and his declining further surgery. CONCLUSIONS: In this report, we add to the knowledge base on this exceedingly rare tumor, review the small number of relevant cases published previously, and analyze and summarize the clinical and pathological characteristics, treatment options and prognosis of this cancer.

RESUMO

BACKGROUND: Despite being one of the most common types of fracture, there is a lack of epidemiological studies involving ankle fractures of all kinds. Since 2012, the Swedish Fracture Register (SFR) has prospectively collected data on surgically and non-surgically treated ankle fractures. The aim of this study is to describe the epidemiology of ankle fractures between 2012 and 2022. METHODS: All ankle fractures registered in the SFR between 1 April 2012 and 31 March 2022 in patients aged 16 years or older were included. Information on age, sex, mechanism of injury, fracture classification according to AO/OTA and high- or low-energy trauma was retrieved from the SFR. RESULTS: During the study period, 56,439 patients sustained 57,443 ankle fractures. Women (61%) were more commonly affected than men (39%). The mean age at the time of injury was 55 years. Men were found to be younger at the time of injury compared with women. Women were found to sustain open fractures more frequently, whereas the men more frequently sustained high-energy trauma. The most common mechanism of injury for all ankle fractures and for each AO/OTA44 fracture group separately was a simple fall. A seasonal variation in ankle fractures was found, where the number of ankle fractures peaked during the between November and March. CONCLUSIONS: This study presents the epidemiology of all AO/OTA types of ankle fractures. We have demonstrated that most ankle fractures are caused by a simple fall and occur during wintertime. Women are more commonly affected than men and are older at the time of injury. These findings indicate that age-related skeletal fragility, as well as an increasing risk of simple falls in the elderly, may be risk factors for ankle fractures. This study will contribute to the planning of primary prevention for ankle fractures.

RESUMO

BACKGROUND: The Philadelphia chromosome encodes the BCR-ABL fusion protein, which has two primary subtypes, P210 and P190. P210 and P190 cause Philadelphia-positive chronic myeloid leukemia (Ph+ CML) and Philadelphia-positive acute lymphoblastic leukemia (Ph+ ALL), respectively. The Ph+ ALL is more malignant than Ph+ CML in disease phenotype and progression. This implies the key pathogenic molecules and regulatory mechanisms caused by BCR-ABL in two types of leukemia are different. It is reported that STAT6 was significantly activated only in P190 transformed cells. However, the potential role and the mechanism of STAT6 activation in Ph+ ALL and its activation mechanism by P190 are still unknown. METHODS: The protein and mRNA levels of STAT6, c-Myc, and other molecules were measured by western blot and quantitative real-time PCR. The STAT6 inhibitor AS1517499 was used to specifically inhibit p-STAT6. The effect of p-STAT6 inhibition on Ph+ CML and Ph+ ALL cells was identified by CCK-8 and FCM assay. Dual luciferase reporter and ChIP assay were performed to confirm the direct binding between STAT6 and c-Myc. The impact of STAT6 inhibition on tumor progression was detected in Ph+ CML and Ph+ ALL mouse models. RESULTS: Our results demonstrated that P210 induced CML-like disease, and P190 caused the more malignant ALL-like disease in mouse models. STAT6 was activated in P190 cell lines but not in P210 cell lines. Inhibition of STAT6 suppressed the malignancy of Ph+ ALL in vitro and in vivo, whereas it had little effect on Ph+ CML. We confirmed that p-STAT6 regulated the transcription of c-Myc, and STAT6 was phosphorylated by p-Jak2 in P190 cell lines, which accounted for the discrepant expression of p-STAT6 in P190 and P210 cell lines. STAT6 inhibition synergized with imatinib in Ph+ ALL cells. CONCLUSIONS: Our study suggests that STAT6 activation plays an essential role in the development of Ph+ ALL and may be a potential therapeutic target in Ph+ ALL. Video abstract.

RESUMO

OBJECTIVE: According to the different characteristics of patients and cervical lymph node metastasis of oral and oropharyngeal cancer, the marginal mandibular branches of facial nerves were treated by different surgical procedures, and the safety and protective effects of different surgical procedures were investigated. METHODS: One hundred ninety-seven patients with oral and oropharyngeal cancer satisfying the inclusion criteria were selected. According to the different characteristics of patients and cervical metastatic lymph nodes, three different surgical procedures were used to treat the marginal mandibular branches of the facial nerve: finding and exposing the marginal mandibular branches of the facial nerves at the mandibular angles of the platysma flaps, finding and exposing the marginal mandibular branches of facial nerves at the intersections of the distal ends of facial arteries and veins with the mandible, and not exposing the marginal mandibular branches of the facial nerves. The anatomical position, injury, and complications of the marginal mandibular branches of the facial nerves were observed. RESULTS: The marginal mandibular branches of the facial nerves were found and exposed at the mandibular angles of the platysma flaps in 102 patients; the marginal mandibular branches of facial nerves were found and exposed at the intersections of the distal ends of the facial arteries and veins with the mandibles in 64 patients; the marginal mandibular branches of facial nerves were not exposed in 31 patients; among them, four patients had permanent injury of the marginal mandibular branches of the facial nerves, and temporary injury occurred in seven patients. There were statistically significant differences in the protection of the mandibular marginal branch of the facial nerve among the three different surgical methods (P = 0.0184). The best protective effect was to find and expose the mandibular marginal branch of the facial nerve at the mandibular angle of the platysma muscle flap, and the injury rate was only 2.94%. CONCLUSION: The three different surgical procedures were all safe and effective in treating the marginal mandibular branches of the facial nerves, the best protective effect was to find and expose the mandibular marginal branch of the facial nerve at the mandibular angle of the platysma muscle flap.

RESUMO

BACKGROUND: Functioning and non-functioning adrenocortical adenoma are two subtypes of benign adrenal adenoma, and their differential diagnosis is crucial. Current diagnostic procedures use an invasive method, adrenal venous sampling, for endocrinologic assessment. METHODS: This study proposes establishing an accurate differential model for subtyping adrenal adenoma using computed tomography (CT) radiomic features and machine learning (ML) methods. Dataset 1 (289 patients with adrenal adenoma) was collected to develop the models, and Dataset 2 (54 patients) was utilized for external validation. Cuboids containing the lesion were cropped from the non-contrast, arterial, and venous phase CT images, and 1,967 features were extracted from each cuboid. Ten discriminative features were selected from each phase or the combined phases. Random forest, support vector machine, logistic regression (LR), Gradient Boosting Machine, and eXtreme Gradient Boosting were used to establish prediction models. RESULTS: The highest accuracies were 72.7%, 72.7%, and 76.1% in the arterial, venous, and non-contrast phases, respectively, when using radiomic features alone with the ML classifier of LR. When features from the three CT phases were combined, the accuracy of LR reached 83.0%. After adding clinical information, the area under the receiver operating characteristic curve increased for all the machine learning methods except for LR. In Dataset 2, the accuracy of LR was the highest, reaching 77.8%. CONCLUSION: The radiomic features of the lesion in three-phase CT images can potentially suggest the functioning or non-functioning nature of adrenal adenoma. The resulting radiomic models can be a non-invasive, low-cost, and rapid method of minimizing unnecessary testing in asymptomatic patients with incidentally discovered adrenal adenoma.

RESUMO

BACKGROUND: Prostate cancer (PCa) and obesity are two ever-increasing public health issues that can independently impair the quality of life (QOL) of affected patients. Our objective was to evaluate the impact of overweight and obesity on the QOL of patients with PCa receiving an anticancer treatment. METHODS: We performed a systematic review of the literature using PubMed, Embase, Cochrane Library and Web of Science databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The search equation targeted studies that included PCa patients who had a body mass index (BMI) greater than 25 kg/m2, who were receiving anticancer therapy, and whose QOL was analyzed according to validated or non-validated scores. RESULTS: Of 759 identified articles, we selected 20 studies published between 2000 and 2019 of 12,529 patients treated for PCa, including 5549 overweight or obese patients. QOL assessment was performed using nine validated scales and two non-validated questionnaires. Of seven studies on radiotherapy, six found obesity to have a negative impact on patients' QOL (especially urinary, sexual, and bowel-related QOL). Thirteen studies assessed the QOL of patients who underwent radical prostatectomy, with a BMI > 25 kg/m2 having no observed impact. In obese patients under 65 years of age and without comorbidities, nerve-sparing surgery appeared to limit the deterioration of QOL. Four studies on brachytherapy found discordant results. One study showed greater QOL impairment in obese patients receiving first-generation hormone therapy than in those with normal or decreased BMI. No study evaluated the QOL of overweight or obese patients receiving other types of systemic treatment. CONCLUSION: Based on the published data, the level of evidence for an association between QOL and overweight or obesity in patients treated for PCa is not high. Prospective cohort studies including this type of patient population are warranted to answer this topical public health issue.

RESUMO

BACKGROUND: Telemedicine support virtual consultations and evaluations in hand surgery for patients in remote areas during the COVID-19 era. However, traditional physical examination is challenging in telemedicine and it is inconvenient to manually measure the hand range of motion (ROM) from images or videos. Here, we propose an automatic method using the hand pose estimation technique, aiming to measure the hand ROM from smartphone images. METHODS: Twenty-eight healthy volunteers participated in the study. An eight-hand gestures measurement protocol and the Google MediaPipe Hands were used to analyze images and calculate the ROM automatically. Manual goniometry was also performed according to the guideline of the American Medical Association. The correlation between the automatic and manual methods was analyzed by the intraclass correlation coefficient and Pearson correlation coefficient. The clinical acceptance was testified using Bland-Altman plots. RESULTS: A total of 32 parameters of each hand were measured by both methods, and 1792 measurement results were compared. The mean difference between automatic and manual methods is -2.21 ± 9.29° in the angle measurement and 0.48 ± 0.48 cm in the distance measurement. The intraclass correlation coefficient of 75% of parameters was higher than 0.75, the Pearson correlation coefficient of 84% of parameters was over 0.6, and 40.6% of parameters reached well-accepted clinical agreements. CONCLUSIONS: The proposed method provides a helpful protocol for automatic hand ROM measurement based on smartphone images and the MediaPipe Hands pose estimation technique. The automatic measurement is acceptable and comparable with existing methods, showing a possible application in the telemedicine examination of hand surgery.

RESUMO

Inherited ocular diseases comprise a heterogeneous group of rare and complex diseases, including inherited retinal diseases (IRDs) and inherited optic neuropathies. Recent success in adeno-associated virus-based gene therapy, voretigene neparvovec (Luxturna®) for RPE65-related IRDs, has heralded rapid evolution in gene therapy platform technologies and strategies, from gene augmentation to RNA editing, as well as gene agnostic approaches such as optogenetics. This review discusses the fundamentals underlying the mode of inheritance, natural history studies and clinical trial outcomes, as well as current and emerging therapies covering gene therapy strategies, cell-based therapies and bionic vision.

RESUMO

Background: Quantification of urinary tissue inhibitor of metalloproteinase-2 (TIMP-2) and insulin-like growth factor binding protein (IFGBP-7), which is commercially known as NephroCheck™(NC) test have been suggested as promising tools for the early detection of acute kidney injury (AKI) after cardiac surgery involving cardio-pulmonary bypass (CPB). Objectives: The aim of the present study was to test the hypothesis that single value of postoperative NC test performed at 4 hours after surgery can predict AKI in off-pump coronary artery bypass grafting (OPCABG) surgery. Setting and Design: This prospective single-center study was conducted at the tertiary cardiac center in India from December 2017 to November 2018. Methods: Ninety adult patients of both sex undergoing elective OPCABG were included. Anesthesia was standardized to all patients. Urine samples were collected preoperatively and at 4 hours after surgery for NC test. Urine output, serum creatinine, estimated glomerular filtration rate (eGFR) were also measured. AKI staging was based on kidney disease improving global outcomes (KDIGO) guidelines. Statistical Analysis: To assess the predictability of NC test for the primary endpoint, area under the receiver operating characteristic curve (ROC), was calculated. Results: Thirteen patients developed AKI in the study cohort (14.4%) out of which 7 patients (7.8%) developed stage 2/3 AKI and the remaining stage 1 AKI. Baseline renal parameters were similar between AKI and non-AKI group. The area under curve (AUC) of NC test at 4 hours after surgery was 0.60 [95% confidence interval (CI): 0.42-0.77]. Postoperative NC test performed at 4 hours after surgery did not predict AKI in this study population (P = 0.24). There were no significant differences in duration of mechanical ventilation, length of intensive care stay and hospital stay between the two groups (P > 0.05). Conclusion: NephroCheck™ test performed at 4 hours after surgery did not identify patients at risk for developing AKI following OPCABG surgery.

RESUMO

OBJECTIVE: to associate the presence and grading of adverse dermatoneurological events (peripheral neuropathy and hand-foot syndrome) and the interference in the activities of daily living of patients with gastrointestinal neoplasms undergoing systemic antineoplastic treatment. METHOD: this is a longitudinal, prospective study, using instruments to assess hand-foot syndrome and peripheral neuropathy. RESULTS: there were 36 patients: 66.7% diagnosed with colon cancer and 83.2% on combination therapy. From cycle 5 onwards, all of them had hand-foot syndrome, with a majority of grade 1, unrelated to interference in activities of daily living. Regarding peripheral neuropathy, there was a moderate to strong correlation from cycle 1 of treatment. CONCLUSION: peripheral neuropathy negatively affects activities of daily living. The monitoring of dermatoneurological events by oncology nurses contributes to the clinical practice of nursing and subsidizes the development of advanced practice in the country.

RESUMO

BACKGROUND: Carpal tunnel syndrome (CTS) is a very common clinical syndrome manifested by signs and symptoms of irritation of the median nerve at the carpal tunnel in the wrist. Direct and indirect costs of CTS are substantial, with estimated costs of two billion US dollars for CTS surgery in the USA in 1995 alone. Local corticosteroid injection has been used as a non-surgical treatment for CTS many years, but its effectiveness is still debated. OBJECTIVES: To evaluate the benefits and harms of corticosteroids injected in or around the carpal tunnel for the treatment of carpal tunnel syndrome compared to no treatment or a placebo injection. SEARCH METHODS: We used standard, extensive Cochrane search Methods. The searches were 7 June 2020 and 26 May 2022. SELECTION CRITERIA: We included randomised controlled trials (RCTs) or quasi-randomised trials of adults with CTS that included at least one comparison group of local injection of corticosteroid (LCI) into the wrist and one group that received a placebo or no treatment. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcome was 1. improvement in symptoms at up to three months of follow-up. Our secondary outcomes were 2. functional improvement, 3. improvement in symptoms at greater than three months of follow-up, 4. improvement in neurophysiological parameters, 5. improvement in imaging parameters, 6. requirement for carpal tunnel surgery, 7. improvement in quality of life and 8. ADVERSE EVENTS: We used GRADE to assess the certainty of evidence for each outcome. MAIN RESULTS: We included 14 trials with 994 participants/hands with CTS. Only nine studies (639 participants/hands) had useable data quantitatively and in general, these studies were at low risk of bias except for one quite high-risk study. The trials were conducted in hospital-based clinics across North America, Europe, Asia and the Middle East. All trials used participant-reported outcome measures for symptoms, function and quality of life. There is probably an improvement in symptoms measured at up to three months of follow-up favouring LCI (standardised mean difference (SMD) -0.77, 95% confidence interval (CI) -0.94 to -0.59; 8 RCTs, 579 participants; moderate-certainty evidence). Up to six months this was still evident favouring LCI (SMD -0.58, 95% CI -0.89 to -0.28; 4 RCTs, 234 participants/hands; moderate-certainty evidence). There is probably an improvement in function measured at up to three months favouring LCI (SMD -0.62, 95% CI -0.87 to -0.38; 7 RCTs, 499 participants; moderate-certainty evidence). We are uncertain if there is a difference in median nerve DML at up to three months of follow-up (mean difference (MD) -0.37 ms, 95% CI -0.75 to 0.02; 6 RCTs, 359 participants/hands; very low-certainty evidence). The requirement for surgery probably reduces slightly in the LCI group at one year (risk ratio 0.84, 95% CI 0.72 to 0.98; 1 RCT, 111 participants, moderate-certainty evidence). Quality of life, measured at up to three months of follow-up using the Short-Form 6 Dimensions questionnaire (scale from 0.29 to 1.0; higher is better) probably improved slightly in the LCI group (MD 0.07, 95% CI 0.02 to 0.12; 1 RCT, 111 participants; moderate-certainty evidence). Adverse events were uncommon (low-certainty evidence). One study reported 2/364 injections resulted in severe pain which resolved over "several weeks" and 1/364 injections caused a "sympathetic reaction" with a cool, pale hand that completely resolved in 20 minutes. One study (111 participants) reported no serious adverse events, but 65% of LCI-injected and 16% of the placebo-injected participants experienced mild-to-moderate pain lasting less than two weeks. About 9% of participants experienced localised swelling lasting less than two weeks. Four studies (229 participants) reported that they experienced no adverse events in their studies. Three studies (220 participants) did not specifically report adverse events. AUTHORS' CONCLUSIONS: Local corticosteroid injection is effective for the treatment of mild and moderate CTS with benefits lasting up to six months and a reduced need for surgery up to 12 months. Where serious adverse events were reported, they were rare.

RESUMO

Diabetes affects every tissue in the body, including the skin. The main skin problem is the increased risk of infections, which can lead to foot ulcers. Most studies evaluating the effects of diabetes on the skin are carried out in wound healing areas. There are fewer studies on uninjured skin, and some particularities of this tissue are yet to be elucidated. In general, cellular and molecular outcomes of diabetes are increased oxidative stress and lipid peroxidation. For our study, we used C57BL/6 mice that were divided into diabetic and non-diabetic groups. The diabetic group received low doses of streptozotocin on 5 consecutive days. To evaluate the effects of hyperglycemia on uninjured skin, we performed morphological analysis using hematoxylin/eosin staining, cellular analysis using Picrosirius red and Nissl staining, and immunostaining, and evaluated protein expression by polymerase chain reaction. We confirmed that mice were hyperglycemic, presenting all features related to this metabolic condition. Hyperglycemia caused a decrease in interleukin 6 (Il-6) and an increase in tumor necrosis factor alpha (Tnf-α), Il-10, F4/80, tumor growth factor beta (Tgf-ß), and insulin-like growth factor 1 (Igf-1). In addition, hyperglycemia led to a lower cellular density in the epidermis and dermis, a delay in the maturation of collagen fibers, and a decrease in the number of neurons. Furthermore, we showed a decrease in Bdnf expression and no changes in Ntrk2 expression in the skin of diabetic animals. In conclusion, chronic hyperglycemia in mice induced by streptozotocin caused disruption of homeostasis even before loss of skin continuity.

RESUMO

Functional constipation (FC) is one of the most common gastrointestinal disorders characterized by hard stools and infrequent bowel movements, which is associated with dysfunction of the enteric nervous system and intestinal motility. Luteolin, a naturally occurring flavone, was reported to possess potential pharmacological activities on intestinal inflammation and nerve injury. This study aimed to explore the role of luteolin and its functional mechanism in loperamide-induced FC mice. Our results showed that luteolin treatment reversed the reduction in defecation frequency, fecal water content, and intestinal transit ratio, and the elevation in transit time of FC models. Consistently, luteolin increased the thickness of the muscular layer and lessened colonic histopathological injury induced by loperamide. Furthermore, we revealed that luteolin treatment increased the expression of neuronal protein HuC/D and the levels of intestinal motility-related biomarkers, including substance P (SP), vasoactive intestinal polypeptide (VIP), and acetylcholine (ACh), as well as interstitial cells of Cajal (ICC) biomarker KIT proto-oncogene, receptor tyrosine kinase (C-Kit), and anoctamin-1 (ANO1), implying that luteolin mediated enhancement of colonic function and contributed to the anti-intestinal dysmotility against loperamide-induced FC. Additionally, luteolin decreased the upregulation of aquaporin (AQP)-3, AQP-4, and AQP-8 in the colon of FC mice. In summary, our data showed that luteolin might be an attractive option for developing FC-relieving medications.
