Purpose:
Treatment outcomes of locally advanced rectal cancer have improved significantly in recent decades. This retrospective study aimed to assess the efficacy of neoadjuvant chemoradiotherapy (nCRT) followed by surgery in patients with T4 rectal cancer and the different outcomes between T4a and T4b patients.
Materials and Methods:
A total of 60 clinically T4 rectal cancer patients who underwent nCRT were included in the analysis. Patient characteristics, treatment regimens, down-staging rates, pathological response, and overall survival (OS) were evaluated.
Results:
Both T4a and T4b patients experienced down-staging following nCRT (36.6% and 6.2% respectively; p = 0.021). T4a patients exhibited a higher rate of pathological complete response (pCR) than T4b patients (13.3% in T4a vs. 0% in T4b; p = 0.122). After a median follow-up of 36 months, the OS and recurrence-free survival (RFS) of T4a patients were significantly higher compared to T4b patients (hazard ratio [HR] = 2.52, 95% confidence interval [CI] 1.05–6.05, p = 0.038 for OS; HR = 2.32, 95% CI 1.09–4.92, p = 0.025 for RFS).
Conclusion
This study provides valuable insights into the effectiveness of nCRT in T4 rectal cancer patients. Although down-staging was observed in both T4a and T4b subgroups, achieving a pCR remains a challenge, particularly in T4b patients. Further research is needed to optimize treatment strategies and enhance pCR rates in T4 rectal cancer patients to improve oncologic outcomes.

Osong Public Health and Research Perspectives 2023;14(3):180-187
Objectives:
This study aimed to examine the effect of the coronavirus disease 2019 (COVID-19) outbreak on the hospitalization rate, emergency department (ED) visits, and outpatient clinic visits in western Iran.
Methods:
We collected data on the monthly hospitalization rate, rate of patients referred to the ED, and rate of patients referred to outpatient clinics for a period of 40 months (23 months before and 17 months after the COVID-19 outbreak in Iran) from all 7 public hospitals in the city of Kermanshah. An interrupted time series analysis was conducted to examine the impact of COVID-19 on the outcome variables in this study.
Results:
A statistically significant decrease of 38.11 hospitalizations per 10,000 population (95% confidence interval [CI], 24.93–51.29) was observed in the first month of the COVID-19 outbreak. The corresponding reductions in ED visits and outpatient visits per 10,000 population were 191.65 (95% CI, 166.63–216.66) and 168.57 (95% CI, 126.41–210.73), respectively. After the initial reduction, significant monthly increases in the hospitalization rate (an increase of 1.81 per 10,000 population), ED visits (an increase of 2.16 per 10,000 population), and outpatient clinic visits (an increase of 5.77 per 10,000 population) were observed during the COVID-19 pandemic.
Conclusion
Our study showed that the utilization of outpatient and inpatient services in hospitals and clinics significantly declined after the COVID-19 outbreak, and use of these services did not return to pre-outbreak levels as of June 2021.

PURPOSE:
To identify risk factors for developing pressure ulcers (PUs) in the acute care period of traumatic spinal fracture patients with or without spinal cord injuries (SCIs).
METHODS:
Data were collected prospectively in participating the National Spinal column/Cord Injury Registry of Iran (NSCIR-IR) from individuals with traumatic spinal fractures with or without SCIs, inclusive of the hospital stay from admission to discharge. Trained nursing staff examined the patients for the presence of PUs every 8 h during their hospital stay. The presence and grade of PUs were assessed according to the European Pressure Ulcer Advisory Panel classification. In addition to PU, following data were also extracted from the NSCIR-IR datasets during the period of 2015 - 2021: age, sex, Glasgow coma scale score at admission, having SCIs, marital status, surgery for a spinal fracture, American Spinal Injury Association impairment scale (AIS), urinary incontinence, level of education, admitted center, length of stay in the intensive care unit (ICU), hypertension, respiratory diseases, consumption of cigarettes, diabetes mellitus and length of stay in the hospital. Logistic regression models were used to estimate the unadjusted and adjusted odds ratio (OR) with 95% confidence intervals (CI).
RESULTS:
Altogether 2785 participants with traumatic spinal fractures were included. Among them, 87 (3.1%) developed PU during their hospital stay and 392 (14.1%) had SCIs. In the SCI population, 63 (16.1%) developed PU during hospital stay. Univariate logistic regression for the whole sample showed that marital status, having SCIs, urinary incontinence, level of education, treating center, number of days in the ICU, age, and Glasgow coma scale score were significant predictors for PUs. However, further analysis by multiple logistic regression only revealed the significant risk factors to be the treating center, marital status, having SCIs, and the number of days in the ICU. For the subgroup of individuals with SCIs, marital status, AIS, urinary incontinence, level of education, the treating center, the number of days in the ICU and the number of days in the hospital were significant predictors for PUs by univariate analysis. After adjustment in the multivariate model, the treating center, marital status (singles vs. marrieds, OR = 3.06, 95% CI: 1.55 - 6.03, p = 0.001), and number of days in the ICU (OR = 1.06, 95% CI: 1.04 - 1.09, p < 0.001) maintained significance.
CONCLUSIONS
These data confirm that individuals with traumatic spinal fractures and SCIs, especially single young patients who suffer from urinary incontinence, grades A-D by AIS, prolonged ICU stay, and more extended hospitalization are at increased risk for PUs; as a result strategies to minimize PU development need further refinement.

The association between the risk of allograft rejection after organ transplantation and FAS gene polymorphism has been evaluated previously. However, inconsistent results have been reported. Hence, we conducted the most up-to-date meta-analysis to evaluate this association. All eligible studies reporting the association between FAS-670A>G polymorphism and the risk of allograft rejection published up to December 2019 were extracted using a comprehensive systematic database search in the Web of Science, Scopus, and PubMed. The pooled odds ratios (OR) and corresponding 95% confidence intervals (CI) were calculated to determine the association strength. This meta-analysis included six case-control studies with 277 patients who experienced allograft rejection and 1,001 patients who did not experience allograft rejection (controls) after organ transplantation. The overall results showed no significant association between FAS-670A>G polymorphism and the risk of allograft rejection in five genetic models (dominant model: OR=0.81, 95% CI=0.58‒1.12; recessive model: OR=0.10, 95% CI=0.80‒1.53; allelic model: OR=0.96, 95% CI=0.79‒1.18; GG vs. AA: OR=0.92, 95% CI=0.62‒1.36; and AG vs. AA: OR=0.75, 95% CI=0.52‒1.08). Moreover, subgroup analysis according to ethnicity and age did not reveal statistically significant results. Our findings suggest that FAS-670A>G polymorphism is not associated with the risk of allograft rejection after organ transplantation.

OBJECTIVES: The present study aimed to compare the quality of life of elderly menopause living in urban/rural areas of Abadeh, Iran. METHODS: This descriptive and cross-sectional study was conducted on 312 urban and 68 rural elderly population using the two-stage (systematic random classification) and objective-based sampling methods. Data were collected by Leiden-Padua questionnaire for assessment of quality of life in elderly menopause. SPSS software (version 21) and descriptive-analytical tests were used for data analysis. RESULTS: The results showed that the overall quality of life was 37.5 and 34.2 in rural and urban areas, respectively, and no statistically significant difference was observed between them. However, there was statistically significant difference in the mean score of depression and anxiety, cognitive function, social function, life satisfaction, and sexual activity in urban and rural elderly menopause (P < 0.001). CONCLUSIONS: It seems necessary to pay more attention to the elderly menopause to improve their quality of life and consider proper planning for their empowerment and coping skills training.

The purpose of this review study is to evaluate sexual function and its effective factors in menopause. A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The key words of “menopause,” “postmenopause,” “postmenopausal,” “premenopause,” “pre-menopausal period,” “sexual function,” “sexual health,” “sexuality,” “sexual and gender disorders,” “sexual development,” “sexual dysfunction,” “sexual disorders,” “sexual behavior and “sexual activity” were used in combination with the Boolean operators OR and AND. After reviewing the selected articles, 27 papers were selected based on the criteria for entering the study and the goals set. The results of the reviewed articles showed that, in the physical domain, the factors affecting sexual function can be mentioned, age, hormonal changes, medical problems and reproductive history. Sexual disorders in menopause can be affected by some of the individual and social characteristics and psychological problems. Considering the fact that many psychological and social injuries occur in this period following sexual disorders; therefore, policies and programs for improving the quality of life of women in menopause should be aimed at eliminating sexual dysfunction, correcting attitudes and negative emotions and help to women for more comfortable in menopause.
