Aplicabilidade de protocolo odontológico de assistência materno-infantil na atenção básica à saúde / Applicability of a maternal and child dental care protocol in basic health care / Aplicabilidad de un protocolo dental de atención materno-infantil en la atención básica de salud

A atenção materno-infantil enfrenta diversos desafios na assistência odontológica. Assim, este estudo teve por objetivo desenvolver e analisar a aplicabilidade de um Protocolo Odontológico de Assistência Materno-Infantil (POAMI) em uma unidade básica de saúde do município de Mossoró/RN. Trata-se de um estudo transversal desenvolvido com trinta gestantes de fevereiro a dezembro de 2021. Inicialmente foram aplicados na primeira consulta os questionários "Investigação do Conhecimento das Gestantes sobre sua Saúde Bucal e a do seu Bebê" (ICGSBB) e o Oral Health Impact Profile (OHIP-14). Em seguida, o POAMI foi aplicado em consultas agendadas e na última consulta o questionário ICGSBB foi reaplicado. Observou-se na primeira consulta que apenas 3,33% (n=1) das gestantes tinham conhecimentos sobre a doença periodontal (27,27% (n=6) na última consulta), 10,34% (n=3) indicavam o uso do creme dental com flúor (95,45% (n=21) na última consulta) e 55,17% (n=16) da fralda molhada para higiene bucal do bebê (100% (n=22) na última consulta). Na avaliação do OHIP-14, 23,33% (n=7) das gestantes estão classificadas dentro do nível "Médio Impacto". O POAMI demonstrou ser aplicável na atenção básica e eficaz na melhoria dos conhecimentos das gestantes, no aumento considerável da cobertura e acesso, e na motivação de boas práticas de higiene oral.

Maternal and child care faces several challenges in dental care. This study aimed to develop and analyze the applicability of a Maternal and Child Dental Care Protocol in a basic health unit in Mossoró/RN. This cross-sectional study involved 30 pregnant women from February to December 2021. Initially, the "Investigação do Conhecimento das Gestantes sobre sua Saúde Bucal e a do seu Bebê" (ICGSBB) and the Oral Health Impact Profile (OHIP-14) questionnaires were applied in their first consultation. The protocol was then applied in scheduled consultations, and the ICGSBB questionnaire was reapplied in the last consultation. In the first consultation, only 3.33% (n=1) of the pregnant women had knowledge about periodontal disease (27.27% (n=6) in the last consultation), 10.34% (n=3) indicated the use of fluoride toothpaste (95.45% (n=21) in the last consultation), and 55.17% (n=16) knew to use a wet diaper for the oral hygiene of their children (100% (n=22) in the last consultation). The OHIP-14 evaluation showed that 23.33% (n=7) of the pregnant women fell within its "medium impact" level. The protocol proved to be applicable in basic care, effectively improving pregnant women's knowledge, increasing coverage and access, and motivating good oral hygiene.

Diagnóstico humanizado: El paciente en el centro - la comunicación que cura / Diagnóstico humanizado: O paciente no centro - comunicação que cura / Humanized Diagnosis: The pacient at the center - communication that Heals

Este texto plantea la importancia de confeccionar protocolos de diagnóstico humanizado que permitan a los profesionales de la salud brindar información sobre patologías y/o discapacidades de manera clara y veraz, humana y delicadamente, facilitando su recepción por parte del paciente y su familia. El diagnóstico humanizado no forma parte únicamente de un protocolo de "urbanidad" en el vínculo médico ­ paciente: es parte integrante y relevante del procedimiento o tratamiento. Este abordaje exige una mirada interdisciplinar. En esta temática hay elementos que se vinculan a lo médico ­ científico; lo jurídico ­ legislativo ­ jurisprudencial y lo político.

Ao longo deste texto, discute-se a importância da elaboração de protocolos diagnósticos humanizados que permitam aos profissionais de saúde fornecerem informações sobre patologias e/ou incapacidades de forma clara e verdadeira, ao mesmo tempo em que humanizada e delicada, facilitando seu acolhimento pelo paciente e sua família. O diagnóstico humanizado não é apenas parte de um protocolo de "civilidade" na relação médico-paciente, mas parte integrante e relevante do procedimento para realizar o tratamento de uma doença ou deficiência. Essa abordagem requer uma abordagem interdisciplinar. Nessa disciplina há elementos que se vinculam ao médico-científico; as esferas jurídica, legislativa e política.

Throughout this text, the importance of creating humanized diagnostic protocols is discussed. These should allow healthcare professionals to provide clear and truthful information about pathologies and/or disabilities in a humane and delicate manner, facilitating their understanding by the patient and their family. Humanized diagnosis is not just part of a "politeness" protocol in the doctor-patient relationship, but an integral and relevant part of the procedure for treating a disease or disability. This approach requires an interdisciplinary perspective, as there are elements that are linked to the strictly medical-scientific, legal-legislative-jurisprudential, and political aspects of this topic.

Dental care in patients with periodontal disease and hearing impairment: a scoping review / Atención odontológica en pacientes con enfermedad periodontal y deficiencia auditiva: scoping review

Introduction: Literature shows that individuals with disabilities, including hearing impairment, often suffer from untreated dental caries, poor oral hygiene, and compromised periodontal health, leading to adverse effects on oral health. Objetive: This study aims to analyze current evidence concerning dental care strategies for controlling, managing, and preventing biofilm accumulation in patients with hearing impairment. Materials and Methods: A systematic search was conducted in the databases Scopus, Web of Science, SciELO and PubMed between April and May 2022 to identify articles establishing a relationship between periodontal disease and hearing disability. Full-text articles published in English or Spanish between 2012 and 2022 were included. Results: Seventeen articles met the inclusion criteria and were analyzed. These included cross-sectional studies, cohort studies, clinical trials, case reports, and case-control studies. Most studies reported fair to poor oral health status among individuals. Nine different interventions or management approaches for treating periodontal disease in patients with hearing impairment were identified. Conclusions: The current global evidence on the association between periodontal disease and hearing impairment is very limited. Dentists may need to employ various strategies to address communication barriers, as outlined in this study.

Nuevos paradigmas en atrofia muscular espinal de presentación temprana: siempre es bueno recordar / New paradigms in early-onset spinal muscular atrophy: a reminder is always beneficial

La atrofia muscular espinal (AME) de presentación temprana representa la variante más severa, con una expectativa de vida generalmente no mayor a dos años sin soporte ventilatorio, debido a la insuficiencia respiratoria y la dificultad para toser. Tradicionalmente, el manejo respiratorio en muchos países ha incluido la traqueostomía para proporcionar asistencia ventilatoria invasiva de manera continua. No obstante, la introducción de medicamentos de precisión ha modificado la progresión natural de la enfermedad, evidenciando mejoras significativas en los hitos motores y beneficiando también la función respiratoria. A pesar de estas mejoras, en muchos casos sigue siendo necesaria la ventilación intermitente y/o continua, además de la facilitación de la tos. Estas necesidades pueden abordarse de forma no invasiva mediante el soporte ventilatorio no invasivo (SVN), la in-exsuflación mecánica (IEM) y el reclutamiento de volumen pulmonar (RVP), que son considerados pilares del tratamiento respiratorio en enfermedades neuromusculares. Estas estrategias promueven el desarrollo y mantenimiento de la función respiratoria, reduciendo el riesgo de exacerbaciones respiratorias que podrían llevar a intubaciones evitables. Comúnmente, los pacientes con AME experimentan intentos fallidos de extubación siguiendo protocolos tradicionales, siendo catalogados como no extubables y potenciales candidatos a traqueostomía. No obstante, existen protocolos de extubación específicos para AME que emplean SVN e IEM con un alto porcentaje de éxito, evitando traqueostomías innecesarias que pueden complicar la progresión de la enfermedad y afectar la calidad de vida. El enfoque respiratorio no invasivo es una opción de manejo segura tanto en el hospital como en el hogar, ofreciendo una mejor calidad de vida para los pacientes y sus familias.

Early-onset spinal muscular atrophy (SMA) is the most severe variant, with a life expectancy generally not exceeding two years without ventilatory support due to respiratory insufficiency and difficulty in coughing. Traditionally, respiratory management in many countries has included tracheostomy to provide continuous invasive ventilatory support. However, the introduction of precision medicine has altered the natural progression of the disease, showing significant improvements in motor milestones and also benefiting respiratory function. Despite these improvements, many cases still require intermittent and/or continuous ventilation, as well as cough facilitation. These needs can be addressed non-invasively through non-invasive ventilatory support (NIV), mechanical insufflation-exsufflation (MIE), and lung volume recruitment (LVR), which are considered the pillars of respiratory treatment in neuromuscular diseases. These strategies promote the development and maintenance of respiratory function, reducing the risk of respiratory exacerbations that could lead to avoidable intubations. Commonly, SMA patients experience failed extubation attempts following traditional protocols, being labeled as non-extubatable and potential candidates for tracheostomy. Nevertheless, there are specific extubation protocols for SMA that employ NIV and MIE with a high success rate, avoiding unnecessary tracheostomies that can complicate disease progression and impact quality of life. The non-invasive respiratory approach is a safe management option both in the hospital and at home, offering a better quality of life for patients and their families.

Research progress in clinical management of nonalcoholic fatty liver disease / 重庆医学

Nonalcoholic fatty liver disease(NAFLD),also known as metabolic associated fatty liver disease(MAFLD),is one of the most common chronic liver diseases characterized by the fat accumulation in the liver and hepatocellular damage.Patients with NAFLD can manifest as simple fatty liver or non-alcoholic steatohepatitis(NASH)in the early stage,and can progress to hepatic fibrosis,hepatic cirrhosis,hepatic fail-ure,and hepatic carcinoma in the late stage.NAFLD has become the most common chronic liver disease,af-fecting more than 30%of the population worldwide,posing a threat to human health that cannot be ignored.However,the current research on NAFLD is still incomplete,and there is no ideal medication for the treat-ment of NAFLD.The clinical management of NAFLD lacks unified standards and evidence-based evidence,and the multiple comorbidities bring challenges to the clinical management of NAFLD.This article was aimed to review the research progress in the clinical management of NAFLD,including the diagnosis and non-invasive examination methods,evaluation and commonly used tools,treatments methods,advantages and disadvanta-ges,so as to provide a reference for the clinical management of NAFLD.

Research progress on immune checkpoint inhibitors for the treatment of adverse reactions related to gastric cancer / 国际外科学杂志

Traditional chemotherapy is the cornerstone of comprehensive treatment for gastric cancer, but its recurrence and metastasis rates are high, and the overall prognosis is not ideal. The rise of immune checkpoint inhibitors (ICI) has brought new hope to gastric cancer patients and changed the current pattern of comprehensive treatment for gastric cancer. With the increasing use of ICI, immune related adverse reactions (irAEs) such as skin toxicity and gastrointestinal toxicity are becoming increasingly common. Scientific understanding, early diagnosis, and graded management are currently the main strategies for handling irAEs. This article aims to review the mechanisms, clinical manifestations, and prediction, treatment, and management of irAEs after ICI treatment of gastric cancer, in order to enhance the understanding of irAEs among clinical physicians, better manage immunotherapy related adverse reactions, and improve the prognosis and quality of life of patients.

Impact of pembrolizumab combined with chemotherapy on angiogenesis and circulating endothelial cells in patients with advanced non-small cell lung cancer / 国际肿瘤学杂志

Objective:To explore the impact of pembrolizumab combined with chemotherapy on angiogenesis and circulating endothelial cells in patients with advanced non-small cell lung cancer (NSCLC) .Methods:The retrospective analysis of clinical data from 121 patients diagnosed with advanced NSCLC who were admitted to the Second Affiliated Hospital of Xingtai Medical College from August 2021 to January 2023 was conducted. These patients were divided into a control group ( n=57) and an observation group ( n=64) based on the designated treatment protocol. Specifically, individuals in the control group received standard chemotherapy (cisplatin+paclitaxel), while those in the observation group underwent penpilimab therapy in conjunction with conventional chemotherapy. The comparative assessment encompassed short-term clinical efficacy, quality of life, immune function parameters, angiogenic factors [including endostatin, insulin-like growth factor 1 (IGF-1), and vascular endothelial growth factor (VEGF) ], circulating endothelial cells, and adverse reactions within the two groups. Results:After 6 courses of treatment, the objective response rate [67.19% (43/64) vs. 49.12% (28/57) ] and disease control rate [87.50% (56/64) vs. 70.18% (40/57) ] in observation group were higher than those in control group, with statistically significant differences ( χ2=4.06, P=0.044; χ2=5.52, P=0.019). The quality of life score of observation group [ (56.77±6.81) points] was significantly higher than that of control group [ (47.73±8.23) points], with a statistically significant difference ( t=6.61, P<0.001) ; The T cell subgroup CD3 + levels [ (63.59±9.00) % vs. (53.06±8.80%), t=6.49, P<0.001], CD4 + levels [ (46.54±8.20) % vs. (30.74±7.32) %, t=11.13, P<0.001] and CD4 +/CD8 + ratio (1.90±0.36 vs. 1.21±0.28, t=11.66, P<0.001) in observation group were significantly higher than those in control group, with statistically significant differences; Endostatin in observation group [ (48.99±3.43) μmol/L] was significantly higher than that in control group [ (31.35±3.87) μmol/L], with a statistically significant difference ( t=26.58, P<0.001), IGF-1 [ (102.31±20.35) μg/L vs. (134.98±19.02) μg/L] and VEGF [ (31.70±4.32) pg/ml vs. (58.71±5.99) pg/ml] were significantly lower in observation group than those in control group, with statistically significant differences ( t=18.73, P<0.001; t=28.14, P<0.001). The number of circulating endothelial cells in observation group [ (58.77±10.03) /ml] was significantly lower than that in control group [ (87.01±8.01) /ml], with a statistically significant difference ( t=17.20, P<0.001). During treatment, there were no statistically significant differences in the incidence of gastrointestinal reaction ( χ2=0.01, P=0.908), leukopenia ( χ2=0.64, P=0.424), thrombocytopenia ( χ2=0.28, P=0.597), anemia ( χ2=1.66, P=0.197), nephrotoxicity ( χ2=0.64, P=0.424), skin rash ( χ2=1.33, P=0.249) between the two groups. Conclusion:The combination therapy of pembrolizumab and chemotherapy for the treatment of advanced NSCLC has demonstrated noteworthy effectiveness. This regimen has the potential to enhance patients' immune functionality, ameliorate their overall quality of life, suppress angiogenesis, and exhibits a commendable profile of safety and reliability.

The application progress of artificial intelligence technology in the diagnosis and treatment of developmental dysplasia of the hip / 中华骨科杂志

Developmental dysplasia of the hip (DDH) is a developmental disease with abnormal position and morphology of the acetabulum and femoral head. DDH ranges from mild dysplasia to complete dislocation, including simple acetabular dysplasia, subluxation, and total dislocation. DDH is one of the most common hip diseases in children, and its onset begins in infancy. The anatomical structure of the hip joint is complex, and there are some practical problems in the large -scale clinical diagnosis and screening work, such as heavy workload, high misdiagnosis rate and missed diagnosis rate, and a long learning period of surgery. Artificial intelligence (AI) is an emerging technology science used to research and develop theories, methods, technologies and application systems that can simulate human intelligence. The main goal is to enable machines to complete complex tasks that require human intelligence. At present, artificial intelligence is mainly used in the diagnosis and treatment of DDH. Artificial intelligence combined with X-ray or ultrasound is used to diagnose and screen DDH, which avoids subjectivity to a certain extent and improves the accuracy of diagnosis and screening. In the preoperative planning of periacetabular osteotomy and total hip arthroplasty, it can more accurately track the position of the bone block and design the size of the prosthesis, which makes the surgical planning more accurate to a certain extent. Artificial intelligence technologies such as 3D navigation system, surgical robot and robotic arm are helpful to improve the accuracy and safety of surgery. Artificial intelligence has the characteristics of simplicity, speed, high repeatability and deep learning ability, which to a certain extent saves manpower, material resources and time costs for DDH diagnosis and treatment, facilitates medical workers to share DDH diagnosis and treatment experience and reduces the burden of patients, families, society and the country. The application of artificial intelligence in DDH diagnosis and treatment is becoming more and more extensive, but at present, artificial intelligence in DDH screening is still in its preliminary stage. There are few reports on artificial intelligence technology in DDH hip preservation treatment and other surgical methods, and there is insufficient research on artificial intelligence in DDH conservative treatment, postoperative complications and prognosis prediction. It is worth exploring new ideas by researchers. At present, the application of artificial intelligence in DDH still has certain limitations, including problems such as difficult to control the quality of image data, difficult to develop and promote technology, and lack of laws and regulations. Based on the literature database and relevant data sharing network, this paper reviews the application of artificial intelligence in the diagnosis and treatment of DDH at home and abroad in recent years, summarizes the current application status of artificial intelligence in the diagnosis and treatment of DDH, and provides new ideas for the future application of artificial intelligence in the diagnosis and treatment of DDH.

Effect and safety of preoperative short-course radiotherapy combined with neoadjuvant chemotherapy for elderly patients with locally advanced rectal cancer / 中华老年医学杂志

Objective:To assess the impact of preoperative short-course radiotherapy combined with neoadjuvant chemotherapy on elderly patients with locally advanced rectal cancer after a 2-year follow-up.Methods:In this retrospective cohort study, we included 446 consecutive cases of elderly patients diagnosed and treated for locally advanced rectal cancer(stage Ⅱ-Ⅲ with T3-T4 and/or positive regional lymph nodes)at the First People's Hospital of Shangqiu city from January 2012 to December 2019.The patients were divided into two groups based on the treatment method: an observation group(107 cases)and a control group(339 cases).The patients in the observation group underwent preoperative short-course radiotherapy combined with neoadjuvant chemotherapy.The regimen included short-term radiotherapy(25 Gy over 1 week in 5 fractions)followed by 4 courses of chemotherapy(CAPOX regimen).On the other hand, the control group received concurrent radiotherapy and chemotherapy.The regimen involved 50 Gy over 5 weeks in 25 fractions and concurrent capecitabine chemotherapy.Afterward, total rectal mesentery resection was performed, and postoperatively, 2 and 6 courses of CAPOX chemotherapy were continued.Follow-up was conducted until 31 December 2021, with the primary observation being the disease-free survival(DFS)of patients in both groups.Secondary observations included overall survival(OS)time, lesion progression-free survival(PFS)time, local recurrence rate, and the rate of acute toxicity events.Cox regression analyses were conducted to compare the factors influencing DFS.Results:Among the 446 patients, 303(67.9%)were male and 143(32.1%)were female.The patients in the observation group were found to be younger and had a higher proportion of Eastern Collaborative Oncology Group(ECOG)physical status score 0 compared to the control group(both P<0.05).Additionally, the two groups differed significantly in terms of MRI T stage, N stage, distance from the external anal verge, rectal mesorectal fascial infiltration, pathological stage, and chemotherapy-to-surgery time interval(all P<0.05).Throughout a mean follow-up period of(20.7±3.5)months, there were 76 deaths, 89 distant metastases, and 32 local recurrences.The results of Kaplan-Meier survival analysis revealed that the observation group had a higher disease-free survival(DFS)rate at 2 years of follow-up compared to the control group[73.8%(79/107) vs.68.1%(231/339), Log-rank χ2=2.676, P=0.041].Additionally, the median DFS time was longer in the observation group[19(12, 22)months]compared to the control group[16(11, 19)months]( Z=2.774, P=0.038).Furthermore, the observation group exhibited a significantly longer OS time[26(21, 33)months]compared to the control group[22(18, 14)months]( Z=2.879, P=0.032).However, the median PFS time was similar in both groups[20(14, 25)months vs.16(12, 21)months]( Z=1.545, P=0.123).The incidence of distant metastasis was 18.7%(20/107)in the observation group and 20.4%(69/339)in the control group(Log-rank χ2=0.341, P=0.708), indicating no significant difference.Similarly, there was no significant difference in the risk of local recurrence between the observation group[9.3%(10/107)]and the control group[6.5%(22/339)](Log-rank χ2=0.996, P=0.318).In terms of adverse reactions, there was no statistically significant difference in the incidence of grade≥3 acute toxic reactions between the two groups[19.6%(21/107) vs.12.1%(41/339), Log-rank χ2=1.661, P=0.148].A multifactorial Cox regression analysis revealed that age( HR=0.586, P=0.005), ECOG score( HR=0.721, P=0.028), MRI T-stage( HR=0.605, P=0.008), rectal mesenteric fascial infiltration( HR=1.649, P=0.012), and distance from the external anal verge( HR=0.638, P=0.041)were associated with DFS. Conclusions:The findings indicate that the combination of preoperative short-course radiotherapy and neoadjuvant chemotherapy in elderly patients with locally advanced rectal cancer demonstrates favorable short-term effectiveness and safety.This approach shows promise in improving outcomes for elderly patients with locally advanced rectal cancer.

Study on the efficacy of beat chemotherapy in treating non-small cell lung cancer / 中华老年医学杂志

Objective:To assess the effectiveness and safety of beat chemotherapy in treating non-small cell lung cancer, and to investigate its anti-tumor molecular mechanism.Methods:In this study, we developed a subcutaneous tumor model of lung cancer in mice.The mice were subsequently divided into two groups: the beat chemotherapy group and the placebo group(negative control group).Throughout the treatment period, we monitored the changes in body weight and tumor size of the mice.At the conclusion of the treatment, we collected blood samples from the mice to conduct blood routine and biochemical examinations.Furthermore, we obtained tumor tissues from the mice to perform immunohistochemical staining and sequencing of the transcriptome.Results:The study found that beat chemotherapy could effectively delay the growth of lung cancer.The tumor tissues in the beat chemotherapy group were significantly smaller compared to the placebo group.The results of routine blood and blood biochemistry tests showed that the levels of red blood cells(RBCs), white blood cells(WBCs), alanine aminotransferase(ALT), aspartate aminotransferase(AST)and blood creatinine(Scr)were similar between the placebo group and the beat chemotherapy group.The values for RBCs, WBCs, ALT, AST and Scr in the placebo group were(6.97 ± 0.41)× 10 12/L, (13.26 ± 0.29)× 10 9/L, (33.33 ± 2.51)U/L, (235.33 ± 57.62)U/L and(20.67 ± 2.08)μmol/L, respectively.The corresponding values in the beat chemotherapy group were(6.87 ± 0.66)× 10 12/L, (12.59 ± 2.27)× 10 9/L, (38.67 ± 3.79)U/L, (225.33 ± 6.81)U/L and(20.33 ± 3.79)μmol/L.Statistical analysis showed no significant differences between the two groups( t=0.509, 0.209, 2.032, 0.299, 0.134, P=0.638, 0.845, 0.112, 0.780, 0.900).Furthermore, there were no signs of inflammatory infiltration or pathological changes in the liver, kidney, spleen, and lung tissues of the mice.Transcriptome analysis identified 68 differentially expressed genes, which were mainly associated with signal transduction and immunity.Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis revealed the involvement of several signaling pathways, including the transforming growth factor β(TGF-β)signaling pathway, the interleukin-17(IL-17)signaling pathway, and the tumor necrosis factor(TNF)signaling pathway. Conclusions:The use of chemotherapy has been proven to be safe and effective in treating non-small cell lung cancer.It primarily functions by regulating tumor growth through various signaling pathways, including the TGF-β signaling pathway, IL-17 signaling pathway, and TNF.

Value of renal biopsy in the diagnosis and treatment of adult patients with acute kidney disease / 中华肾脏病杂志

Objective:To analyze the changes of diagnosis and treatment before and after renal biopsy in adult patients with acute kidney disease (AKD), and to explore the value of renal biopsy in the diagnosis and treatment of AKD.Methods:It was a single-center retrospective observational study. The adult patients with AKD who underwent renal biopsy in the Department of Nephrology of the First Affiliated Hospital of Nanjing Medical University from January 1, 2017 to December 31, 2021 were enrolled. Demographic data, general clinical data, laboratory tests, and diagnosis and treatment data before and after renal biopsy were collected to analyze the concordance rate between clinical and pathological diagnoses, changes in treatment after renal biopsy, and bleeding complication.Results:A total of 575 patients diagnosed with AKD by renal biopsy were included in this study, with age of 51 (36, 63) years old and 359 males (62.4%). Among them, there were 293 patients (51.0%) of acute kidney injury, 348 patients (60.5%) of hypertension and 124 patients (21.6%) of diabetes. The peak serum creatinine was 272 (190, 477) μmol/L. The hemoglobin was 106 (86, 126) g/L. The 24-hour urine protein was 2.15 (0.79, 4.82) g. There were 347 patients (60.3%) of acute glomerular diseases, 136 patients (23.7%) of acute interstitial nephritis, 47 patients (8.2%) of thrombotic microangiopathy, and 45 patients (7.8%) of acute tubular necrosis. The most common types of acute glomerular diseases were IgA nephropathy and anti-neutrophil cytoplasmic antibody-associated glomerulonephritis, accounting for 22.3% (128/575) and 12.2% (70/575), respectively. The clinical diagnoses before renal biopsy were consistent with the renal histopathological diagnoses in 454 patients, with an accuracy rate of 79.0%. Following the renal biopsy, the treatment plan involving glucocorticoids or immunosuppressants was adjusted in 394 patients (68.5%). Significant post-biopsy bleeding occurred in 15 patients (2.6%), with 12 patients requiring blood transfusion and 1 patient requiring surgical intervention.Conclusions:Twenty-one clinical diagnoses do not match the pathological diagnoses in adult AKD patients, 68.5% of patients have changes in their treatment plans, and 2.6% of patients have significant hemorrhagic complications after renal biopsy. Clinicians need to carefully consider the benefits and risks and make individualized decisions about renal biopsy.

Efficacy and safety of deep hyperthermia combined with sintilimab and nab-PC regimen in the treatment of advanced squamous non-small cell lung cancer with driver gene negative and PD-L1 expression positive / 肿瘤研究与临床

Objective:To investigate the clinical efficacy and safety of deep hyperthermia combined with sintilimab and nab-PC (albumin-bound paclitaxel + carboplatin) regimen in the treatment of advanced squamous non-small cell lung cancer (NSCLC) with driver gene negative and programmed death-1 receptor ligand 1 (PD-L1) expression positive.Methods:A prospective case-control study was performed. A total of 84 advanced squamous NSCLC patients with driver gene negative and PD-L1 expression positive in Hebei Seventh People's Hospital from January 2020 to December 2022 were collected, and all patients were divided into the observation group and the control group according to the random number table method, with 42 cases in each group. The control group was given the treatment of sintilimab combined with nab-PC regimen, and the observation group was given deep hyperthermia on the basis of the control group. After 4 consecutive cycles of treatment, the short-term efficacy of the two groups was compared. The levels of serum tumor markers [carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCA), cytokeratin fragment 19 (CYFR21-1)], and the positive expression rates of immunohistochemistry markers [p40, p63, and cytokeratin 5/6 (CK5/6)] before and after treatment were compared between two groups. Functional Assessment of Cancer Therapy-Lung cancer module (FACT-L) scores, the adverse reactions and the long-term survival of the two groups were compared.Results:There were 26 males and 16 females in the observation group, and the age was (59±11) years; there were 22 males and 15 females in the control group, and the age was (58±11) years. The objective remission rate and the disease control rate were 71.43% (30/42), 90.48% (38/42), respectively in the observation group, and 50.00% (21/42), 80.95% (34/42), respectively in the control group; the objective remission rate in the observation group was higher than that in the control group, and the difference was statistically significant ( χ2 = 4.04, P = 0.044); and there was no statistically significant difference in the disease control rate of both groups ( χ2 = 1.56, P = 0.212). The levels of serum CEA, SCCA and CYFRA21-1, and the positive expression rates of p40, p63, and CK5/6 in the two groups after treatment were lower than those before treatment (all P < 0.05); and the scores of physiological status, functional status, additional concern in FACT-L scores and the total score of the scale after treatment were higher than those before treatment (all P < 0.05). There were no statistically significant differences in the incidence of adverse reactions including thrombocytopenia, neutropenia, leukopenia, anemia, fever of the two groups (all P > 0.05). The median progression-free survival (PFS) time was 6.5 months (95% CI: 3.82-12.75), 5.1 months (95% CI: 3.14-12.26),respectively in the observation group and the control group, and the difference in the median PFS time was statistically significantly of both groups ( χ2 = 4.21, P = 0.040). The median overall survival (OS) time was 12.9 months (95% CI: 6.25-15.46), 9.7 months (95% CI: 4.74-13.02), respectively in the observation group and the control group, and the difference in the median OS time was statistically significantly of both groups ( χ2 = 4.43, P = 0.035). Conclusions:Deep hyperthermia combined with sintilimab and nab-PC regimen in the treatment of advanced squamous NSCLC with driver gene negative and PD-L1 expression positive can effectively reduce the serum tumor markers levels and positive expression rate of immunohistochemical markers, improve the quality of life of patients, and increase the short-term and long-term efficacy.

Research progress in diagnosis and treatment of scrotal masses / 中国基层医药

Scrotal mass is a common problem in the outpatient department of urology, accounting for 1% of all emergency patients. The diagnosis of scrotal masses is challenging due to the overlapping symptoms and signs of various scotal masses. Failure to correctly identify and treat scrotal masses, such as testicular torsion, testicular cancer, varicocele, and hydrocele, may lead to infertility, testicular loss, or even death. Misdiagnosis or missed diagnosis of scrotal masses may result in infertility, testicular loss, or even death. Therefore, we must maintain a high degree of vigilance and accurately identify scrotal masses that may affect life and testicular function. A full understanding of the manifestations and differences of various scrotal masses can help clinicians make accurate diagnoses and provide optimal treatment plans. The most critical aspect is to exclude emergency situations that may endanger life or testicular function, such as testicular torsion, testicular cancer, and necrotizing fasciitis, which require immediate medical attention. Scrotal ultrasonography is the best method for distinguishing scrotal masses based on their origin. Magnetic resonance imaging is the best tool for diagnosing scrotal hematoma. However, good clinical judgment and decision-making are still the most important factors for successful treatment of scrotal masses. The purpose of this article is to describe correct evaluation methods for scrotal masses and identify potential conditions that may threaten testicular survival, enabling accurate pathological diagnosis, evaluation, and treatment plans for each scrotal mass.

Clinical efficacy of tirellizumab combined with chemotherapy in the treatment of advanced non-small cell lung cancer / 中国基层医药

Objective:To investigate the efficacy of tirellizumab combined with chemotherapy in the treatment of advanced non-small cell lung cancer and its effect on immune function and quality of life in patients.Methods:In this retrospective case-control study, we analyzed the clinical data of 104 patients with advanced (stages III and IV) non-small cell lung cancer who received treatment at Zhoushan Hospital between May 2021 and June 2022. These patients were divided into two groups: group A ( n = 52) and group B ( n = 52), based on the treatment methods utilized. Patients in group A received chemotherapy with gemcitabine plus cisplatin or pemetrexed plus cisplatin. Meanwhile, patients in group B were treated with tirellizumab combined with chemotherapy regimens of gemcitabine plus cisplatin or pemetrexed plus cisplatin, with 21 days as a treatment cycle. Both groups of patients received three cycles of treatment. The short-term efficacy was compared between the two groups. Additionally, serum levels of tumor markers, immune function indexes, quality of life score, and incidence of adverse reactions were compared between the two groups before and after treatment. Results:The short-term response rate in group B was significantly higher than that in group A [51.92% (27/52) vs. 32.69% (17/52), Z = 4.11, P < 0.001]. When compared with pretreatment levels, serum levels of tumor markers and the percentage of CD8 + cells decreased in both groups after treatment. Notably, the serum levels of tumor markers and the percentage of CD8 + cells were significantly lower in group B compared with group A (all P < 0.05). Moreover, after treatment, the percentage of CD4 + cells, the ratio of CD4 +/CD8 + cells, functional subscale, symptom subscale, and total score increased significantly compared with pretreatment levels (all P < 0.05) and were significantly higher in group B compared with those in group A (all P < 0.05). The incidence of adverse events in group B was significantly higher than that in group A [44.23% (23/52) vs. 21.15% (11/52), χ2 = 6.29, P = 0.012]. Conclusion:Tirelizumab combined with chemotherapy is effective for advanced non-small-cell lung cancer. The combined therapy can lower serum levels of tumor markers, restore immune function, and improve overall quality of life.

Effects of Kanglaite injection combined with chemotherapy on quality of life and myelosuppression in patients with non-small cell lung cancer / 中国基层医药

Objective:To investigate the effects of Kanglaite injection combined with chemotherapy on quality of life and myelosuppression in patients with non-small cell lung cancer (NSCLC).Methods:The clinical data of 60 patients with NSCLC who received treatment at Zhejiang Jinhua Guangfu Tumor Hospital from August 2018 to February 2022 were retrospectively analyzed. These patients were divided into an experimental group and a control group, with 30 patients in each group according to the treatment methods used. The patients in the experimental group received the Kanglaite injection in combination with chemotherapy using gemcitabine and cisplatin, whereas the patients in the control group were treated solely with chemotherapy with gemcitabine and cisplatin. The quality of life was evaluated using the Karnofsky Performance Status score. Before and after treatment, a comparison was made between the two groups in terms of Karnofsky Performance Status score, the incidence of adverse reactions (such as myelosuppression), and clinical efficacy.Results:After treatment, the disease control rate and objective response rate in the experimental group were 86.67% (26/30) and 60.00% (18/30), respectively, which were significantly higher than 60.00% (18/30) and 30.00% (9/30) in the control group ( χ2 = 4.18, 4.31, both P < 0.05). Prior to treatment, the Karnofsky Performance Status scores in the experimental and control groups were (70.68 ± 3.75) points and (70.29 ± 5.11) points ( t = 0.34, P = 0.790), respectively. After treatment, the Karnofsky Performance Status scores in the experimental group were significantly higher than those in the control group [(67.02 ± 5.87) points vs. (62.37 ± 3.59) points, t = -5.29, P < 0.05]. The incidence of adverse reactions in the experimental group was significantly higher than that in the control group [40.00% (12/30) vs. 36.67% (11/30), χ2 = 0.07, P = 0.790). Additionally, the incidence of myelosuppression in the experimental group was significantly lower than that in the control group [56.67% (17/30) vs. 86.67% (26/30), χ2 = 6.90, P = 0.030]. Conclusion:Compared with chemotherapy alone, Kanglaite injection combined with chemotherapy can effectively relieve the clinical symptoms of patients with advanced non-small cell lung cancer, leading to improved prognosis.

Multidisciplinary treatment program for improvement in pain and disability associated with nonspecific chronic low back pain / Programa de tratamento multidisciplinar para melhora da dor e incapacidade associada a dor crônica lombar inespecífica

ABSTRACT BACKGROUND AND OBJECTIVES: Lumbar disorders, which contribute to significant workplace absenteeism and chronic disability, are associated with a considerable financial and social burden. Although a conservative approach provides satisfactory pain relief, biomechanical improvement and is associated with a low risk of adverse effects, there is lack of consensus in the literature regarding the best therapeutic strategy in such cases. METHODS: This retrospective longitudinal study used secondary data from the institutional medical records of patients who completed a multidisciplinary program for the treatment of low back pain between 2019 and 2021. Data regarding pain levels and motor skills were obtained from patients who completed the care program at a private hospital in Bento Gonçalves, RS. The following step-wise treatment algorithm was used: evaluation by a specialist physician for the etiological diagnosis of pain, pharmacological management and dry needling, followed by standard rehabilitation intervention performed by the physiotherapy team and exercises by the physical education team. The visual analogue scale (VAS) was used to measure pain at the start and at the completion of the intervention, and the Oswestry Disability Index (ODI) was used to measure motor skills at the start and at 6 and 12 months following the multiprofessional intervention for rehabilitation. RESULTS: A reduction in pain and motor disability in patients who completed all stages of the treatment program was observed. Pain by the VAS presented the following scores: baseline 7 [5-8] and after treatment 2 [0-4]; and the scores of the ODI were: at baseline 0.34 [0.26 - 0.40], at 6 months 0.16 [0.08 - 0.26] and after treatment 0.12 [0.04 - 0.21]. CONCLUSION: The treatment program reduced the pain and disability associated with low back pain and can serve as the basis for further studies carried out to confirm the effectiveness of this intervention.

RESUMO JUSTIFICATIVA E OBJETIVOS: As doenças lombares, que contribuem para um absenteísmo significativo no local de trabalho e para a incapacidade crônica, estão associadas a um encargo financeiro e social considerável. Embora a abordagem conservadora proporcione alívio satisfatório da dor, melhore a biomecânica e esteja associada a baixo risco de efeitos adversos, não há consenso na literatura sobre a melhor estratégia terapêutica nesses casos. MÉTODOS: Neste estudo longitudinal retrospectivo, foram utilizados dados secundários dos prontuários médicos institucionais de pacientes que completaram um programa multidisciplinar para tratamento de dor lombar entre 2019 e 2021. Dados sobre níveis de dor e habilidades motoras foram obtidos de pacientes que completaram o programa assistencial de um hospital privado de Bento Gonçalves, RS. Foi utilizado o seguinte tratamento passo a passo: avaliação por médico especialista para diagnóstico etiológico da dor, manejo farmacológico e agulhamento a seco, seguido de intervenção de reabilitação padrão realizada pela equipe de fisioterapia e exercícios pela equipe de educação física. A escala analógica visual (EAV) foi utilizada para medir a dor no início e após a conclusão da intervenção, e o Índice de Incapacidade de Oswestry (ODI) foi usado para medir as habilidades motoras no início e aos 6 e 12 meses após a intervenção multiprofissional para reabilitação. RESULTADOS: Observou-se redução na dor e na incapacidade motora em pacientes que completaram todas as etapas do programa de tratamento. A intensidade da dor medida pela EAV apresentou as seguintes pontuações: basal 7 [5-8] e após tratamento 2 [0-4]; enquanto o ODI apresentou as pontuações: basal 0,34 [0,26 - 0,40], até 6 meses 0,16 [0,08 - 0,26] e após o tratamento 0,12 [0,04 - 0,21]. CONCLUSÃO: O programa de tratamento reduziu a dor e a incapacidade associadas à dor lombar e pode servir de base para novos estudos realizados para confirmar a eficácia desta intervenção.

Autopercepção do Impacto Imediato na Voz de Cantores Gospel após uma Apresentação de uma hora / Self-perception of the Immediate Impact on the Voice of Gospel Singers after a one-hour Presentation

RESUMO Objetivo Investigar o impacto imediato na voz de cantores gospel com e sem queixa vocal após uma apresentação individual de uma hora. Método Aplicação de um questionário online que abordou os seguintes aspectos: 1 - Dados sociodemográficos; 2 - Autoavaliação da habilidade de cantar pelo protocolo Evaluation of the Ability to Sing Easily (EASE-BR); 3 - Autoavaliação de sintomas de fadiga vocal pelo Índice de Fadiga Vocal (IFV); e 4 - Autoavaliação da desvantagem vocal pelo protocolo Índice de Desvantagem Vocal 10 (IDV-10). Os participantes foram divididos em dois grupos: Grupo Com Queixa (CQ) e Grupo Sem Queixa (SQ) com base no escore total do IDV-10. Os dados passaram por análise estatística descritiva e inferencial considerando o nível de significância de 5%. Resultados Participaram 43 cantores gospel com idade mediana de 34 anos, divididos entre 32 do grupo SQ e 11 do grupo CQ. O grupo CQ autorrelatou rouquidão e maior dificuldade ao cantar no EASE e maiores escores nos protocolos IDV-10 e IFV. Foi evidenciada correlação positiva entre a dificuldade ao cantar e a desvantagem vocal com a fadiga de cantores amadores gospel, sendo que essa correlação foi maior para o grupo SQ. Conclusão Cantores com queixa vocal apresentaram maiores índices de fadiga vocal, desvantagem vocal e maior dificuldade para cantar após uma hora de apresentação. Cantores sem queixa podem ter a habilidade de cantar prejudicada pela fadiga vocal. Variações na habilidade ao cantar e desvantagens vocais de cantores amadores gospel podem ter relação direta com a fadiga vocal.

ABSTRACT Purpose To investigate the immediate impact on the voice of gospel singers with and without vocal complaints after a one-hour individual presentation. Methods Application of an online questionnaire that addressed the following aspects: 1 - Sociodemographic data; 2 - Self-assessment of the ability to sing using the Evaluation of the Ability to Sing Easily (EASE-BR) protocol; 3 - Self-assessment of vocal fatigue symptoms using the Vocal Fatigue Index (VFI) protocol; and 4 - Self-assessment of voice handicap using the Voice Handicap Index 10 (VHI-10) protocol. Participants were divided into two groups: Group with Vocal Complaint (WVC) and Group with no Vocal Complaint (WnVC) based on the total score of the IDV-10. Data underwent descriptive and inferential statistical analysis with a significance level of 5%. Results The study included 43 gospel singers with a median age of 34 years: 32 were in the WnVC group and 11 were in the WVC group. The WVC group reported hoarseness and experienced more difficulty while singing in the EASE, resulting in higher scores in both the VHI-10 and VFI protocols. A positive correlation was observed between singing difficulty and vocal handicap due to fatigue in amateur gospel singers, with this correlation being stronger within the WnVC group. Conclusion After one hour of performance, singers with vocal complaints exhibited higher rates of vocal fatigue, vocal disadvantage, and greater difficulty in singing. Singers without complaints may have their ability to sing impaired by vocal fatigue. Variations in singing ability and vocal handicaps in amateur gospel singers may be directly related to vocal fatigue.

Association between preoperative fasting time and clinical outcomes in surgical patients in a private general hospital

ABSTRACT Purpose: Surgical patients are routinely subjected to long periods of fasting, a practice that can exacerbate the metabolic response to trauma and impair postoperative recovery. The aim of this study was to evaluate the association between preoperative fasting time and clinical outcomes in surgical patients. Methods: An observational, prospective study with a non-probabilistic sample that included patients of both sexes, aged over 18, undergoing elective surgeries. Data were extracted from electronic medical records, and a questionnaire was applied in 48 hours after surgery. Variables related to postoperative discomfort were assessed using an 11-point numeric rating scale. Results: The sample consisted of 372 patients, and the duration of the surgical event ranged from 30-680 minutes. The incidence of nausea (26.34%) was twice that of vomiting (13.17%) and showed an association with the surgical procedure's size (p = 0.018). A statistically significant difference was observed only between pain intensity and preoperative fasting times for liquids (p = 0.007) and postoperative fasting time (p = 0.08). The occurrence of postoperative complications showed no association with preoperative fasting time (p = 0.850). Conclusions: Although no association was observed between preoperative fasting time and surgical complications, it is noteworthy that both recommended and actual fasting time exceeded the proposed on clinical guidelines.

Protocolo assistencial de acolhimento em unidade de pronto atendimento no contexto da Covid-19 (2020-2021) / Care protocol for reception in an emergency care unit in the context of COVID-19 (2020-2021)

Resumo Pesquisa qualitativa tipo pesquisa-ação cujo objetivo foi descrever o processo de reorganização do fluxo assistencial de uma UPA para o enfrentamento da pandemia de Covid-19, a partir da implantação de protocolos assistenciais. O problema coletivo foi a organização do fluxo de atendimento de pessoas com síndrome gripal (SG). O estudo considerou os ciclos da pesquisa-ação propostos por Tripp (2005). Na fase de planejamento foi desenvolvido o fluxo de atendimentos de pacientes com SG mediante análise de normativas, estrutura física e recursos disponíveis. Durante a implementação, foram estabelecidas parcerias intersetoriais para adequação física, capacitação dos profissionais e redimensionamento da equipe. A descrição do processo de planejamento e implementação deu-se por meio de relatórios e dados coletados dos equipamentos de gestão da unidade e da Secretaria Municipal de Saúde. A avaliação foi realizada de forma contínua, com base na retroalimentação da literatura e da prática refletida. A reorganização da unidade com implantação de protocolos assistenciais e divisão de fluxos evidenciou pontos positivos, como participação e envolvimento da equipe, revisão de processos, busca por evidências e parcerias intersetoriais; e negativos, como a dificuldade na segregação do paciente com SG dentro da estrutura física da UPA.

Abstract Qualitative action-research research aimed to describe the process of reorganizing the care flow of a UPA to face the COVID-19 pandemic, based on the implementation of care protocols. The collective problem was the organization of the care flow for people with the flu syndrome (FS). The study considered the action-research cycles proposed by Tripp (2005). In the planning phase, the flow of care for patients with FS was developed through the analysis of regulations, physical structure, and available resources. During implementation, intersectoral partnerships were established for physical adaptation, training of professionals, and resizing of the team. The planning and implementation process was described based on reports and data were collected from the unit's management equipment and the Municipal Health Department. The evaluation was carried out continuously, based on feedback from the literature and reflected practice. The reorganization of the unit with the implementation of protocols and division of flows showed positive points, such as participation and involvement of the team, review of processes, search for evidence, and intersectoral partnerships; and negative, such as the difficulty in separating FS patients within the physical structure of the UPA.
