Vertebral fractures are frequent clinical consequences of osteoporosis. Considering the demographic change in Europe, the number of vertebral fractures will quite likely increase during the next decades. Apart from pharmaceutic agents and physiotherapy, spinal orthoses are established elements of conservative therapy for vertebral (body) fractures. Recent studies on acute vertebral fractures reported positive effects on back pain, kyphosis and functional disabilities, but the efficacy of active strengthening spinal orthoses in vertebral fractures ≥6 months remains to be established. Eighty hyperkyphotic, community-dwelling women ≥65 years with chronic back pain and vertebral fractures occurred ≥3 months ago were randomly allocated to a group which wore the "Spinomed active" orthoses 2 × 2-3 h/d for 16 weeks (SOG:  = 40) or an untreated control group (CG:  = 40). Study outcomes were back pain intensity, kyphosis angle, trunk strength, back pain induced- and general function and disability, functional ability (chair-rise test) and respiratory function. We applied an intention-to-treat analysis; data were consistently adjusted for baseline values applying an ANCOVA. Observing a compliance of 82 ± 14% with the wearing protocol, we determined large and significant favorable effects for back pain ( = .008), back pain-induced physical disability ( < .001) and kyphosis angle ( < .001). We also demonstrated positive effects on trunk strength ( = .049), functional ability ( = .062) and general function and disability ( = .057), although not all of the parameters reach significance. No relevant changes were observed for respiratory function. After a few further individual adjustments of the orthosis ( = 2), no adverse effects were reported. In summary, the present study provided evidence for the efficacy of an active strengthening spinal orthosis ("Spinomed active") in people with vertebral fractures ≥6 months. Based on our results, we recommend expanding the application of the "Spinomed active" orthosis, which was previously validated for acute vertebral fractures, also to older hyperkyphotic women with osteoporotic vertebral fractures ≥3 months.

A middle-aged, previously healthy male patient presented with high fever, headache, and aching limbs for 3 days. Laboratory results showed signs of acute kidney injury, elevated procalcitonin, and mild thrombocytopenia. On neurological examination, he had no focal neurological deficits, especially no meningism or visual disturbances. Cerebrospinal fluid (CSF) examination showed mild lymphocytic pleocytosis, and magnetic resonance imaging (MRI) revealed a lesion of the splenium corporis callosum. The patient received anti-infective treatment with acyclovir and ceftriaxone until laboratory results returned positive hantavirus IgM and IgG antibodies in the serum indicating an active hantavirus infection. The renal retention parameters and thrombocytopenia receded following treatment with intravenous fluids, analgesic, and antipyretic agents. MRI follow-up 10 days later showed a residual small FLAIR-positive lesion without any persistent callosal diffusion abnormality. The patient was discharged symptom-free after 8 days and had recovered fully 2 months later. The source of infection in this patient remained unclear. Cytotoxic lesions of the corpus callosum (CLCC) are secondary lesions usually with a good prognosis but require further investigation regarding their underlying etiology and should not be confounded with primary callosal lesions, such as ischemia or lymphoma.

Patients with hypermobile Ehlers-Danlos Syndrome (hEDS) often make use of complementary and alternative medical (CAM) techniques to manage their chronic pain and other symptoms. Nevertheless, how they use CAM, which techniques they favor, and how CAM use affects their allopathic care remain unclear. The purpose of this qualitative study was to understand patients' personal experiences with CAM and its role in their symptom management.

Combined therapy for keloids is currently recommended. Surgery is one of the main options, but the measures to prevent recurrence after excision are still being explored.

Studies investigating the association between functional capacity and quality of life (QoL) in individuals with chronic Chagas cardiomyopathy (CCC) usually do not include a gold-standard evaluation of functional capacity, limiting the validity and the interpretation of the results. The present study is a cross-section analysis aiming to evaluate the association between functional capacity (quantified by cardiopulmonary exercise test [CPET]) and QoL in individuals with CCC. QoL was assessed using the SF-36 questionnaire. Sociodemographic, anthropometric, clinical, cardiac function and maximal progressive CPET variables were obtained from PEACH study. Generalized linear models adjusted for age, sex, and left ventricular ejection fraction were performed to evaluate the association between CPET variables and QoL. After adjustments, VO2 peak and VO2 AT were both associated with physical functioning (β = +0.05 and β = +0.05, respectively) and physical component summary (β = +0.03 and β = +0.03, respectively). Double product was associated with physical functioning (β = +0.003), general health perceptions (β = +0.003), physical component summary (β = +0.002), and vitality (β = +0.004). HRR≤12bpm was associated with physical functioning (β = -0.32), role limitations due to physical problems (β = -0.87), bodily pain (β = -0.26), physical component summary (β = -0.21), vitality (β = -0.38), and mental health (β = -0.19). VE/VCO2 slope presented association with all mental scales of SF-36: vitality (β = -0.028), social functioning (β = -0.024), role limitations due to emotional problems (β = -0.06), mental health (β = -0.04), and mental component summary (β = -0.02). The associations between CPET variables and QoL demonstrate the importance of CPET inclusion for a more comprehensive evaluation of individuals with CCC. In this setting, intervention strategies aiming to improve functional capacity may also promote additional benefits on QoL and should be incorporated as a treatment strategy for patients with CCC.

Within the tactical aviation community, human performance research lags in considering potential psychophysiological differences between male and female aviators due to little inclusion of females during the design and development of aircraft systems. A poor understanding of how male and female aviators differ with respect to human performance results in unknown potential sex differences on aeromedically relevant environmental stressors, perchance leading to suboptimal performance, safety, and health guidelines. For example, previous hypoxia studies have excluded female participants or lacked a sizeable sample to examine sex comparisons. As such, progress toward sensor development and improving hypoxia familiarization training are stunted due to limited knowledge of how individual differences, including sex, may or may not underlie hypoxia symptoms and performance impairment. Investigating sex differences bridges the gap between aerospace medicine and operational health, and addressing hypoxia is one of many facets yet to be studied. In the current study, we retrospectively examined N = 6 hypoxia studies with male-female participant samples (total, N = 189; male, = 118; female, = 71). We explored sex as a predictor of physiological response, sensory deficits, the severity of cognitive performance declines, and symptom manifestation linear and binary logistic regression models. We found that the female sex predicted lower peripheral oxygen saturation and the likelihood of headache reporting in response to hypoxic challenge, yet explained little variance when combined with age and body mass index. The sensory and cognitive performance models did not converge, suggesting high intra-individual variability. Together, sex, age, and body mass index were not the most robust predictors in responses to hypoxic challenge; we cannot infer this for sensory deficits and cognitive performance within an experimentally induced hypoxic environment. The findings have implications for improving hypoxia familiarization training, monitoring sensor development, and emergency response and recovery protocols in case of a hypoxia occurrence suitable for all aircrew. We recommend continuing to elucidate the impact of sex and intrapersonal differences in hypoxia and other aeromedically relevant stressors in tactical aviation.

Children with underlying medical conditions potentially develop severe illness from Coronavirus disease 2019 (COVID-19). The use of vaccines against COVID-19 is currently recommended for the pediatric population. The COVID-19 vaccine has a temporal association with the occurrence of myocarditis. Although most patients with COVID-19 vaccination-associated myocarditis (C-VAM) exhibit a mild clinical course and rapid recovery, C-VAM potentially causes electrical instability and sudden cardiac death. Herein, we report the case of a 17-year-old woman who presented with chest pain and syncope following the first dose of the messenger RNA COVID-19 vaccine. The patient's heart function was impaired, and nonsustained ventricular tachycardia was frequent. Cardiac magnetic resonance (CMR) imaging satisfied the criteria for myocarditis. Despite the administration of immunomodulatory drugs, the patient's heart function was not fully restored, and the concentration of cardiac enzymes remained above the normal range. Persistence of late gadolinium enhancement was observed on short-term follow-up CMR imaging. Although most patients with C-VAM exhibit mild symptoms, significant cardiac arrhythmias potentially occur. Furthermore, some patients with C-VAM demonstrate prolonged impaired heart function and sustained late gadolinium enhancement on follow-up CMR imaging. Therefore, monitoring of electrical and functional cardiac abnormalities in patients with C-VAM is crucial and the long-term outcomes and prognosis of patients with C-VAM require further investigation.

Appendicular neoplasms are rare tumors, with an incidence of less than 0.05% among all gastrointestinal tumors. This work presents the case of a 52-year-old patient who manifested colicky pain in the right iliac fossa. Laboratory test results with bandemia and hyperbilirubinemia. Abdominal tomography with an acute appendicular inflammatory process, for which the patient was admitted for surgery. A dependent tumor of the cecum and appendicular region is observed, which compromises the ileocecal valve. The histopathological diagnosis was "low-grade appendiceal mucinous neoplasm." Appendiceal tumors are often incidental findings due to their low frequency; however, their possibility should not be dismissed.
