Incidence and Risk Factors for Amputations in Persons with Diabetes Mellitus: A Retrospective Cohort Study.

The aim of this study was to identify and analyze the incidence rate of amputations and their risk factors in people with Diabetes Mellitus (DM) in two specialized outpatient clinics in Brazil. This is an epidemiological, retrospective cohort study using data collected from electronic health records of 281 adult diabetic patient types 1 or 2; attended in specialized outpatient service between 2015 and 2020. Statistical analyses were performed using the 2 sample t-test or Wilcoxon-Mann-Whitney test, for quantitative variables, and the Pearson's χ2 test or Fisher's exact test for categorical variables.

Epidemiological Profile of Human Papillomavirus in a Healthcare Center in Portugal: Implications for Public Health Policies.

Introduction Human papillomavirus (HPV) infection, a prevalent sexually transmitted disease, affects the majority of sexually active individuals at least once in their lifetime. Cervical cancer stands as a significant contributor to mortality among women. Cervical cancer screening (CCS) and HPV vaccination are recent, with few studies about their impact on the prevalence of HPV types.

A polyvalent RNA vaccine reduces the immune imprinting phenotype in mice and induces neutralizing antibodies against omicron SARS-CoV-2.

Immune imprinting is now evident in COVID-19 vaccinated people. This phenomenon may impair the development of effective neutralizing antibodies against variants of concern (VoCs), mainly Omicron and its subvariants. Consequently, the boost doses with bivalent vaccines have not shown a significant gain of function regarding the neutralization of Omicron.

RNA Combined with Nanoformulation to Advance Therapeutic Technologies.

Nucleic acid-based therapies have the potential to address numerous diseases that pose significant challenges to more traditional methods. RNA-based therapies have emerged as a promising avenue, utilizing nanoformulation treatments to target a range of pathologies. Nanoformulation offers several advantages compared to other treatment modalities, including targeted delivery, low toxicity, and bioactivity suitable for drug loading.

The prevalence of skin tears and associated factors in hospitalised patients with cancer.

Objective: Oncology patients are vulnerable to skin breakdown. The primary purpose of this study was to estimate the prevalence of skin tears (STs) in hospitalised patients with cancer and to explore related sociodemographic and clinical factors.

Method: This was an observational, epidemiological, cross-sectional study conducted in an oncology hospital in the city of São Paulo.

Incidence and Predictive Factors for Amputations Derived From Charcot's Neuroarthropathy in Persons With Diabetes.

Charcot's neuroarthropathy (CN) is the progressive destruction of the bones and joints of the feet, as a consequence of severe peripheral neuropathy, which predisposes patients to amputations. The purpose of this study was to measure the cumulative incidence of amputations resulting from CN and risk factors among amputated people with diabetes mellitus (DM). This was an epidemiological, observational, and retrospective study of 114 patients with DM who had an amputation involving the lower limbs.

Impact of Microphone Configuration on Speech Perception of Cochlear Implant Users in Traffic Noise.

Objective: The aim of this study was to investigate the impact of microphone configuration and noise reduction algorithm on speech perception of cochlear implant (CI) users in a moving noise setup.

Method: Eleven CI users provided with Advanced Bionics implant systems participated in this study. All tests were conducted with three different microphone settings: (a) omnidirectional behind the ear (BTE), (b) inside the pinna (ITP), and (c) adaptive directional microphone (adaptive beamformer, ABF).

[Impact of microphone position on sound localization in cochlear implant users].

Objective: The delivery of directional cues of a hearing device microphone are highly dependent on the position of the microphones. The aim of this work was the evaluation of different microphone positions with regard to the transmission of interaural time and level differences as well as the spectral characteristics and its impact on the localization abilities.

Methods: Head-related transfer functions of 30 subjects were measured with three different omnidirectional microphones at different positions: in the pinna (ITP), behind the ear (BTE), at the entrance of the ear canal (EEC).

[Prevalence of self-reported constipation in adults from the general population].

Objective: To estimate the prevalence of self-reported constipation and associated factors in the general population of a Brazilian city.

Method: Secondary analysis of an epidemiological study, population-based, cross-sectional study, about bowel habits of Brazilian population. A total of 2,162 individuals were interviewed using two instruments: sociodemographic data and the adapted and validated Brazilian version of the "Bowel Function in the Community" tool.
