Diagnostic and Prognostic Performance of Metabolic Signatures in Pancreatic Ductal Adenocarcinoma: The Clinical Application of Quantitative NextGen Mass Spectrometry.

With 64,050 new diagnoses and 50,550 deaths in the US in 2023, pancreatic ductal adenocarcinoma (PDAC) is among the most lethal of all human malignancies. Early detection and improved prognostication remain critical unmet needs. We applied next-generation metabolomics, using quantitative tandem mass spectrometry on plasma, to develop biochemical signatures that identify PDAC. We first compared plasma from 10 PDAC patients to 169 samples from healthy controls. Using metabolomic algorithms and machine learning, we identified ratios that incorporate amino acids, biogenic amines, lysophosphatidylcholines, phosphatidylcholines and acylcarnitines that distinguished PDAC from normal controls. A confirmatory analysis then applied the algorithms to 30 PDACs compared with 60 age- and sex-matched controls. Metabolic signatures were then analyzed to compare survival, measured in months, from date of diagnosis to date of death that identified metabolite ratios that stratified PDACs into distinct survival groups. The results suggest that metabolic signatures could provide PDAC diagnoses earlier than tumor markers or radiographic measures and offer insights into disease severity that could allow more judicious use of therapy by stratifying patients into metabolic-risk subgroups.

Prevalência e desfechos materno-fetais de pacientes internadas por amniorrexe prematura no pré-termo no Hospital Universitário da Faculdade de Medicina de Jundiaí nos anos de 2020 e 2021 / Prevalence and maternal-fetal outcomes in patients hospitalized with preterm premature rupture of membranes at the University Hospital of Jundiaí's Medical School in the years 2020 and 2021

Objetivo: Atualizar a estatística do serviço, reconhecendo a prevalência de amnior- rexe prematura no pré-termo e seus principais desfechos materno-fetais. Méto- dos: Estudo transversal realizado pela análise de prontuários médicos de pacien- tes internadas devido a amniorrexe prematura no pré-termo e de seus respectivos conceptos no Hospital Universitário da Faculdade de Medicina de Jundiaí durante o período de janeiro de 2020 a dezembro de 2021. Resultados: Participaram da pesquisa 161 pacientes e 166 conceptos, resultando em uma prevalência de 2,12% no período estudado, com intervalo de confiança de 95% (1,80-2,47). Entre os des- fechos maternos, 2,5% das gestantes compunham critérios para near miss mater- no; enquanto entre os desfechos fetais, o resultado foi de 54,8% dos conceptos apresentando complicações, sendo as mais prevalentes a síndrome do desconfor- to respiratório (36,3%), icterícia (39,5%), baixo peso (27,5%) e hipoglicemia (24,2%). Além disso, 40,4% necessitaram de internação na unidade de terapia intensiva, 22,9% foram classificados como near miss neonatal e 4,4% foram a óbito. Conclu- são: Os resultados seguiram os padrões nacionais e internacionais esperados para prevalência de amniorrexe prematura no pré-termo e seus desfechos materno-fe- tais, com alta porcentagem de internações e complicações neonatais e baixa taxa de complicações maternas.

Objective: To update service statistics, recognizing the preva- lence of the pathology and its main outcomes. Methods: Cros- s-sectional study carried out through the analysis of medical records of patients hospitalized due to preterm premature rup- ture of membranes and their respective fetuses at the Univer- sity Hospital of Jundiaí's Medical School during the period from January 2020 to December 2021. Results: A total of 161 patients and 166 fetuses participated in the research, resulting in a pre- valence of 2.12% in the period studied with 95% confidence in- terval (1.80-2.47). About the outcomes, 2.5% of the pregnant wo- men composed the criteria for maternal near miss; as for the fetus, complications evolved in 54.8% of the fetuses, the most prevalent being respiratory distress syndrome (36.3%), jaundice (39.5%), low birth weight (27.5%) and hypoglycemia (24.2%). In addition, 40.4% required admission to the intensive care unit, 22.9% were neonatal near miss and 4.4% died. Conclusion: The results followed the expected national and international standards for the prevalence of preterm premature rupture of membranes and its maternal and fetal outcomes, with a high percentage of hospitalizations and neonatal complications, and a low rate of maternal complications.

Hydrocephalus in myelomeningocele.

PURPOSE: To investigate certain aspects of hydrocephalus in patients with myelomeningocele. METHODS: We retrospectively analyzed data of 1050 patients with myelomeningocele who underwent surgical treatment between June 1991 and June 2021. These patients were divided into three groups: group 1 consisted of patients who underwent surgery after the first 6 h of life, group 2 consisted of patients who underwent surgery within the first 6 h, and group 3 consisted of patients who underwent surgery during the fetal period and before 26 6/7 weeks of gestation. RESULTS: There were 125, 590, and 335 patients in groups 1, 2, and 3, respectively. In groups 1 and 2, 593 (83%) patients developed hydrocephalus after birth and required ventriculoperitoneal shunt placement in the maternity ward, mainly within the first 4 days of life. In contrast, in group 3, 24 (7.2%) patients required surgery to treat hydrocephalus after birth. Hydrocephalus was the primary cause of mortality in groups 1 and 2, with mortality rates of 35% and 10%, respectively. In group 3, the mortality rate was 0.8% and was not related to hydrocephalus. CONCLUSION: The onset of hydrocephalus is directly related to myelomeningocele closure in neurosurgery.

Comparative study between two recombinant human NPH insulin formulations for the treatment of type 2 diabetes mellitus.

OBJECTIVE: To compare the effects of the neutral protamine Hagedorn (NPH) recombinant human insulin formulations Gansulin and Humulin N® on the glycemic control of patients with type 2 diabetes mellitus (T2DM). SUBJECTS AND METHODS: Prospective, double-blind, randomized, parallel, single-center study of 37 individuals with T2DM treated with NPH insulin formulations. The Tukey-Kramer test for multiple comparisons, the Wilcoxon paired comparison test and the Chi-Square test were used for the statistical analyses. The significance level was set at 5% (p < 0.05). RESULTS: The NPH insulin formulations Humulin and Gansulin similarly reduced the HbA1c levels observed at the end of the study compared with the values obtained at the beginning of the study. In the Humulin group, the initial HbA1c value of 7.91% was reduced to 6.56% (p < 0.001), whereas in the Gansulin group, the reduction was from 8.18% to 6.65% (p < 0.001). At the end of the study, there was no significant difference between the levels of glycated hemoglobin (p = 0.2410), fasting plasma glucose (FG; p = 0.9257) and bedtime plasma glucose (BG; p = 0.3906) between the two insulin formulations. There was no nt difference in the number of hypoglycemic events between the two insulin formulations, and no severe hyp episodes were recorded. CONCLUSION: This study demonstrated similar glycemic control by NPH insulin Gansulin compared with human insulin Humulin N® in patients with T2DM.

Fisioterapia aquática no paciente sobrevivente da Poliomielite traqueostomizado com suporte ventilatório: relato de caso / Aquatic physical therapy for a poliomyelitis survivor with tracheostomy and ventilatory support: a case report

Muitos pacientes sobreviventes da poliomielite apresentam importante comprometimento da função respiratória. A fisioterapia aquática é indicada para esta população, porém, a presença da traqueostomia leva a uma maior dificuldade de tratamento no meio líquido pela dificuldade da manipulação. O objetivo deste trabalho é verificar os benefícios que uma paciente traqueostomizada, com suporte ventilatório não invasivo, pode ter com a abordagem da fisioterapia aquática. A paciente sofreu intervenção de vinte sessões de fisioterapia aquática. Para avaliação foram usadas as Escalas de Fadiga, Dor e Qualidade de vida e analisados os parâmetros: Saturação de Oxigênio (SatO2), Freqüência Cardíaca (FC)e Freqüência Respiratória (FR). Foi constatada melhora na pontuação de todas as escalas de fadiga utilizadas:inicial 55 e final 28, demonstrando ao final do estudo ausência de fadiga Fator esse também verificado na qualidade de vida principalmente na dimensão de vitalidade inicial 29,16 e final 50. A FC, a (excluir) FR e a SatO2 não sofreram alterações significativas, observando dessa maneira a segurança durante o atendimento. No término do tratamento, o quadro álgico cessou nos principais grupos articulares. Os resultados demonstraram que o meio líquido foi favorável para o tratamento dessa paciente, garantindo a segurança, diminuindo a fadiga e a dor, melhorando assim a qualidade de vida.

Survivors of polio exhibit significant impairment of respiratory function. Aquatic physical therapy is recommended for this population, however, the presence of tracheostomy produces greater difficulty in treatment when using water because of the difficulty involved in moving the patient. The aim of this study is to assess the benefits that a tracheostomized patient with non-invasive ventilatory support, may have with an aquatic therapy approach. The patient underwent an intervention/treatment of twenty sessions of aquatic therapy. The fatigue, pain and quality of life scales were used for evaluation and the parameters were analyzed: Oxygen Saturation (SaO2), heart rate (HR), Respiratory Rate (RR). It was a striking improvement in the scores of all scales used for fatigue: initial 55 and final 28, demonstrating an absence of fatigue at the end of the study. This factor was also observed in the quality of life mainly in the initial (29.16) and final (50) periods of vitality. The HR, RR and SaO2 did not change significantly, demonstrating the safety during the treatment. The pain ceased in the major joints at the end of treatment. The results showed that the use of water was favorable for the treatment of the patient, ensuring safety, reducing fatigue and pain, thereby improving the quality of life.
