Background: Cervical intraepithelial neoplasia (CIN) precedes cervical cancer and it is associated with risk factors that can be identified in the population, which contribute to timely diagnosis and treatment.
Objective: To identify associated risk factors for the development of CIN in women attended at the first level of care.
Material And Methods: A cross-sectional and retrospective study was conducted in women in the 2020-2022 period. Frequencies and means were obtained. For the differences, chi-squared and Student's t were used. Odds ratios (OR) were obtained to assess the risk.
Results: ORs were determined in the group of women with CIN II/CIN III, obtaining risks of almost twice the risk factors analyzed compared to the CIN I group, which had the same factors. When analyzed by age groups < or > 40 years, significant associations were determined in the factors of parity, first cytology in life and positive for smoking. In the group < 40 years and with CIN II/III significant risks were determined in age at first pregnancy < 18 (OR 8.33), first cytology in life (OR 3.77), positive for smoking (OR 3.0), sexual intercourse initiation (SII) before 18 years of age (OR 3.1) and parity (OR 1.3).
Conclusions: According to the results obtained, sexual and reproductive behavioral factors are of high risk for the development of CIN.

TP53 Mutations in Myeloproliferative Neoplasms: Context-Dependent Evaluation of Prognostic Relevance.
Am J Hematol

CRIMM, Center Research and Innovation of Myeloproliferative Neoplasms, University of Florence, AOU Careggi, Florence, Italy.
The clinical relevance of TP53 mutations (TP53) in myeloproliferative neoplasms (MPN) and their prognostic interaction with MPN subtype designation has not been systematically studied. In the current study, 114 patients with MPN harboring TP53 (VAF ≥ 2%) were evaluated for overall survival (OS), calculated from the time of TP53 detection: chronic phase myelofibrosis (MF-CP; N = 61); blast-phase (MPN-BP; N = 31) or accelerated-phase (MPN-AP; N = 16) MPN, and polycythemia vera/essential thrombocythemia (PV/ET; N = 6). Sixty-five (57%) patients harbored International Consensus Classification (ICC)-defined multihit TP53 and 56 (49%) monosomal/complex karyotype (MK/CK).

Objective: This study aimed to assess the trend and factors associated with central obesity in four cross-sectional panels in schoolchildren aged 7-14 years between 2002 and 2019.
Methods: Waist circumference data were used to assess central obesity, and independent variables were gender, age, school shift (morning and afternoon), commuting to school method, mother's schooling, and family income. The chi-square test was used to assess the association between outcome and independent variables, and binary logistic regression was used to assess the predictors of central obesity and the effect size by odds ratio.
Review of Associations of Diabetes and Insulin Resistance With Brain Health in Three Harmonised Cohort Studies of Ageing and Dementia.

Diabetes increases the risk of dementia, and insulin resistance (IR) has emerged as a potential unifying feature. Here, we review published findings over the past 2 decades on the relation of diabetes and IR to brain health, including those related to cognition and neuropathology, in the Religious Orders Study, the Rush Memory and Aging Project, and the Minority Aging Research Study (ROS/MAP/MARS), three harmonised cohort studies of ageing and dementia at the Rush Alzheimer's Disease Center (RADC). A wide range of participant data, including information on medical conditions such as diabetes and neuropsychological tests, as well as other clinical and laboratory-based data collected annually.

Background/purpose: COVID-19 vaccines are supplied at no-cost to residents as a measure to prevent comorbidities, fatalities, and the increased risk of community transmission, thus protecting public health systems. However, vaccine acceptance among cancer patients remained uncertain. This study aimed to elucidate the vaccination rates among oral cancer patients at a medical center in Taiwan.

Background/purpose: Dental management prior to radiotherapy is often time-critical, and there are no studies on whether manipulations such as tooth extraction influence the risk of severe radiation-induced oral mucositis (ROM) during radiotherapy. Therefore, the aim of this study was to describe the relationship between dental management and the incidence of severe ROM.
Materials And Methods: A retrospective analysis was conducted on 144 head and neck cancer (HNC) patients who received dental management before radiotherapy at Peking University Cancer Hospital, from January 2016 to December 2017.
