Clinical-epidemiological evaluation of victims of thoracic trauma in a reference hospital in Aracaju-SE.

INTRODUCTION: thoracic trauma is defined as anything that involves the rib cage, the musculoskeletal framework that houses the heart, lungs, pleurae and mediastinal structures. It can be superficial or immediately lifethreatening for victims. In Brazil, most assistance is due to urban violence. OBJECTIVE: evaluate the clinical and epidemiological aspect of patients who are victims of thoracic trauma treated at Hospital de Urgência de Sergipe, Aracaju/SE, Brazil. METHOD: cross-sectional, observational and prospective study, carried out for eleven months, with 100 polytraumatized patients. A semi-structured form was applied, and the data were systematized, analyzed and statistically tested considering a 5% margin of error. Results: 85% of the patients were male, with a mean age of 39.3 and an age range of 30 to 49 years; 57% of them had incomplete primary education, 70% had a family income of up to 2 minimum wages and 41% were from Greater Aracaju. As for the mechanism of trauma, 33% were car-related, with blunt trauma as the main mechanism, and rib fractures as the main consequence. Among penetrating injuries, CWI (26%) and GSW (21%) were the most prevalent, with hemothorax being the main consequence. Most patients underwent thoracostomy (59%). CONCLUSION: the profile found was of young men, victims of urban violence. The thoracostomy was resolving in most cases and should be instituted promptly when necessary. A smaller number of patients may require thoracotomy, especially in the presence of hemodynamic instability.

COVID-19-Related Acalculous Groove Pancreatitis.

Introduction: Groove pancreatitis is a rare form of chronic pancreatitis. Its radiological diagnosis is challenging and it can be difficult to distinguish from pancreaticoduodenal malignancy. Case description: A 64-year-old woman was admitted to our internal medicine ward after she contracted severe COVID-19 pneumonia requiring mechanical ventilation. She presented with right upper abdominal pain, and a CT scan showed pancreaticoduodenal inflammatory tissue; malignancy was ruled out. Conclusion: Diagnosing groove pancreatitis is challenging and malignancy must be quickly excluded. No cases of COVID-19-associated groove pancreatitis have been previously described. LEARNING POINTS: Groove or paraduodenal pancreatitis is a rare form of chronic pancreatitis, and usually associated with alcohol use.The differential diagnosis includes pancreaticobiliary and duodenal malignancies.Radiological diagnosis is challenging and treatment is usually supportive.

Predictors of Long-COVID-19 and its Impact on Quality of Life: Longitudinal Analysis at 3, 6 and 9 Months after Discharge from a Portuguese Centre.

INTRODUCTION: Long-COVID-19 impacts health-related quality of life (HR-QoL) but data is scarce. The aim of this study was to describe and prospectively assess the prevalence and risk factors for long-COVID-19 after hospital discharge, and to evaluate its impact on patient HR-QoL. MATERIAL AND METHODS: Single-centre longitudinal study including all COVID-19 patients discharged between December 2020 and February 2021. Patients were contacted remotely at three, six and nine months. Data were collected as follows: 1) Long-COVID-19 symptoms were self-reported; 2) HRQoL were assessed using the 3-level EuroQoL-5D (EQ-5D-3L) questionnaire. Pregnant women, demented, bedridden, and non-Portuguese-speaking patients were excluded. RESULTS: The three-, six- and nine-month assessments were completed by 152, 117 and 110 patients (median age: 61 years; male sex: 56.6%). Long-COVID-19 (≥ 1 symptom) was reported by 66.5%, 62.4% and 53.6% of patients and HR-QoL assessment showed impairment of at least some domain in 65.8%, 69.2% and 55.4% of patients at three, six and nine months, respectively. Fatigue was the most common long-COVID-19 symptom. Anxiety/depression domain was the most frequently affected in all three time-points, peaking at six months (39%), followed by pain/discomfort and mobility domains. Long-COVID-19 was associated with the impairment of all EQ-5D-3L domains except for self-care domain at each time-point. Neither intensive care unit admission nor disease severity were associated with long-COVID-19 nor with impairment of any EQ-5D-3L domain. After adjusting for sex, age, frailty status, and comorbid conditions, long-COVID-19 remained significantly associated with HR-QoL impairment at three (OR 4.27, 95% CI 1.92 - 9.52, p < 0.001), six (OR 3.46, 95% CI 1.40 - 8.57, p = 0.007) and nine months (OR 4.13, 95% CI 1.62 - 10.55, p = 0.003) after hospital discharge. In a longitudinal analysis, patients reporting long-COVID-19 at three months had an EQ-5D-3L index value decreased by 0.14 per visit (p < 0.001) compared to those without long-COVID-19 and both groups had a non-significant change in mean EQ-5D-3L index over the nine-month period (time-point assessment, Z = 0.91, p = 0.364). CONCLUSION: Clinical sequelae associated with long-COVID-19 can persist for at least nine months after hospital discharge in most patients and can impair long-term HR-QoL in more than half of patients regardless of disease severity, and clinicodemographic characteristics.

Phenotype of BTK-lacking myeloid cells during prolonged COVID-19 and upon convalescent plasma.

XLA patient with 7-month course of COVID-19 with persistent plasma SARS-CoV-2 load revealed a sustained non-inflammatory profile of myeloid cells in association with contained severity of disease, arguing in favor of the use of BTK inhibitors in SARS-COV-2 infection.

RESUMO Introdução: o trauma torácico é definido como toda aquele que envolve a caixa torácica, arcabouço osteomuscular que aloja o coração, os pulmões, as pleuras e as estruturas do mediastino. Pode ser superficial ou causar risco de vida imediato às vítimas. No Brasil, a maioria dos atendimentos é decorrente da violência urbana. Objetivo: avaliar o aspecto clínico-epidemiológico dos pacientes vítimas de trauma torácico atendidos no Hospital de Urgência de Sergipe, Aracaju/SE, Brasil. Métodos: estudo transversal, observacional e prospectivo, realizado durante onze meses, com 100 pacientes politraumatizados. Formulário semiestruturado foi aplicado, e os dados sistematizados, analisados e testados estatisticamente considerando-se a margem de erro de 5%. Resultados: 85% dos pacientes eram do gênero masculino, com idade média de 39,3 e faixa etária de 30 a 49 anos; 57% deles possuíam ensino fundamental incompleto, 70% tinham renda familiar de até 2 salários mínimos e 41% eram provenientes da Grande Aracaju. Quanto ao mecanismo de trauma, 33% foi automobilístico, tendo como principal mecanismo o trauma contuso, e a principal consequência a fratura de arcos costais. Dentre os ferimentos penetrantes, os FAB (26%) e FAF (21%) foram os mais prevalentes, sendo o hemotórax sua principal consequência, sendo maioria dos pacientes submetida a toracostomia (59%). Conclusão: o perfil encontrado foi de homens, jovens, vítimas da violência urbana. A toracostomia foi resolutiva na maioria dos casos e deve ser instituída prontamente quando necessário. Uma menor parte dos pacientes necessitou de toracotomia, principalmente na presença de instabilidade hemodinâmica.

Leptin, its receptor and aromatase expression in deep infiltrating endometriosis.

BACKGROUND: The aim of this study was to evaluate the leptin levels in the serum and peritoneal fluid (PF) and the protein expression in three different peritoneal ectopic implants in patients who underwent surgery for deep infiltrating endometriosis. METHODS: All patients had been treated at the Department of Gynecology of the Pedro Ernesto University Hospital, Rio de Janeiro. The study group consisted of 15 patients who underwent surgery for adnexal masses and infertility, while the control group consisted of ten women who underwent surgery for tubal ligation. Peritoneal fluid and samples tissues were collected during surgery. Serum samples were obtained before anesthesia. In this study, the leptin levels in the serum and peritoneal fluid (PF) were evaluated by ELISA. The protein expression of leptin and its receptors (ObR) and aromatase enzyme were evaluated by Western blot analysis of the intestine, uterosacral ligament and vaginal septum in the ectopic implants. The t-test and one-way ANOVA with Holm-Sìdak post-test were used, and p < 0.05 was considered to be statistically significant. RESULTS: Compared to the controls, the serum leptin levels (control = 14.7 ng/mL ± 2.63, endometriosis = 19.2 ng/mL ± 1.84, p < 0.0001) were increased, while in PF, there was no difference (control = 6.68 ng/mL ± 0.43, endometriosis = 7.71 ng/mL ± 0.59, p = 0.18). Comparing women with and without ovarian implants, the leptin levels in both the serum and PF were significantly higher in women without ovarian implants (serum: with ovarian implant = 15.85 ± 1.99; without ovarian implant = 23.14 ± 2.60; ng/mL, p = 0.04; PF: with ovarian implant = 4.28 ± 1.30; without ovarian implant = 11.18 ± 2.98;ng/mL, p = 0.048). The leptin, ObR and aromatase protein expression levels were increased in lesions in the vaginal septum and were decreased in the intestine lesions. CONCLUSION: This study reports several interesting associations between the leptin levels in serum, peritoneal fluid, and tissue samples and the localization of the ectopic endometrium. Although this study does not provide a clear picture of the role of leptin in the development and progression of peritoneal implants, it contributed new data that might be useful to elucidating the enigma that is the role of leptin in endometriosis disease.

Increased expression of the leptin receptor in human ovaries affected by endometrioma and detection of high levels of leptin in the ovarian endometriomal fluid.

BACKGROUND: This study was designed to investigate leptin levels in the fluid in ovarian endometriomas (OEs) and to compare the expression of leptin and its receptors (OBR) in ovarian tissue affected by endometrioma in infertile women to its expression in the normal ovarian tissue of fertile controls without endometriosis. METHODS: In this case-control observational study, ovarian tissue, blood samples and peritoneal fluid were obtained from 20 women (10 fertile controls without endometriosis or any ovarian disease, who were undergoing tubal ligation surgery, and 10 infertile women with severe endometriosis and OE). The ovarian endometriomal fluid (EF) was aspirated, and peritoneal-implant (PI) biopsies were performed. The tissues removed during the surgeries were immediately frozen in liquid nitrogen to determine expression levels by western blot and leptin levels by ELISA. RESULTS: OBR was expressed at higher levels in the ovarian tissue affected by endometrioma than in the normal ovarian tissue (control = 0.38 ± 0.05, study = 0.60 ± 0.09, p = 0.03), but there was no significant difference in leptin levels between these groups (control = 0.57 ± 0.1, study = 0.35 ± 0.1, p = 0.18). Positive and significant correlations were observed between leptin and OBR in the OE (r = 0.85, p = 0.004) and in the PI (r = 0.87, p = 0.001). ELISA results demonstrate a greater leptin concentration within the EF compared with the serum and the PF (serum = 14.25 ± 1.63, PF = 5.98 ± 2.0, EF = 73.8 ± 16.2, p = 0.0001), but there was no correlation between these variables. A positive, significant and strong correlation was observed between PF leptin levels and the expression of leptin and OBR in PI (leptin: r = 0.78, p = 0.007/OBR: r = 0.68, p = 0.04) and between the EF leptin levels and the expression of leptin and OBR in the OE (leptin: r = 0.88, p = 0.008/OBR: r = 0.89, p = 0.005). CONCLUSIONS: These data suggest that leptin may play an important role in the physiopathology of OE through a modulatory interaction with its active receptor.

Complicated meningitis caused by a rare serotype of Haemophilus influenzae in Portugal.

We report a case of meningitis due to Haemophilus influenzae serotype d strain in an infant. As far as we know, this is the first report of a serotype d strain, responsible for childhood invasive disease in Europe, demonstrating an emerging of H. influenzae non-b serotype, in the post-vaccination era.
