ABSTRACT

BACKGROUND: Insomnia is a highly common sleep disorder in patients with Parkinson’s disease (PD). Yet, no screening questionnaires following the Diagnostic and Statistical Manual-5 (DSM-5) criteria have been validated in PD patients.

OBJECTIVES: We assessed the validity and reliability of the French version of the sleep condition indicator (SCI), in patients with PD.

METHODS: In a sample of 65 patients (46% women, mean age 63.8 ± 7.9 years) with PD, but without dementia, insomnia was assessed with a clinical interview and the SCI. Statistical analyses were performed to determine the reliability, construct validity, and divergent validity of the SCI. In addition, an explanatory factor analysis was performed to assess the underlying structure of the SCI.

RESULTS: Of the 65 patients (mean duration PD 9.7 ± 6.9 years), 51% met the criteria for insomnia disorder when measured with a clinical interview. The mean SCI score was 18.05 ± 8.3. The internal consistency (α = 0.89) of the SCI was high. Using the previously defined cutoff value of ≤16, the area under the receiver operating characteristic curve was 0.86 with a sensitivity of 86% and a specificity of 87%. Exploratory factor analysis showed a 2-factor structure with a focus on sleep and daytime effects. Additionally, good construct and divergent validity were demonstrated.

CONCLUSION: The SCI can be used as a valid and reliable screener for DSM-5 insomnia disorder in PD patients. Due to its short length, it is useful in both clinical practice and scientific research.

ABSTRACT

INTRODUCTION: The aim of this study was to evaluate long-term safety and efficacy of the suprapubic arc (SPARC) procedure for the surgical treatment of stress urinary incontinence (SUI).

MATERIALS AND METHODS: 139 female patients treated by SPARC were included in this retrospective analysis, whereby 126 patients were available for follow-up after 1 year, 70 after 6 years, and 41 after 9 years. The cough test, pad test, uroflowmetry, and post-void residual volume measurements were performed. Severity of bother (visual analogous scale [VAS] 0-10), continence, and the satisfaction rate were assessed. Objective cure was defined as a negative cough test and pad weight ≤1 g, subjective cure as no urine loss during daily activities and no usage of pads. The VAS, pad weight, number of pads per day, and maximal flow rate were compared preoperatively and postoperatively.

RESULTS: Objective cure rates at 1, 6, and 9 years were 78.6, 71.4, and 70.7% and subjective cure rates were 72.2, 55.7, and 65.8%, respectively. The VAS, pad weight, number of pads, and maximal flow rate decreased significantly. Study limitations include a relatively small sample size and the retrospective fashion of the analysis.

CONCLUSIONS: In the long-term context, SPARC showed to represent an efficient and safe procedure for treatment of female SUI.

ABSTRACT

Evidence suggests that abnormal DNA methylation patterns play a crucial role in the etiology and pathogenesis of colon adenocarcinoma (COAD). In this study, we identified a total of 97 methylation-driven genes (MDGs) through a comprehensive analysis of the Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases. Univariate Cox regression analysis identified four MDGs (CBLN2, RBM47, SLCO4C1, and TMEM220) associated with overall survival (OS) in COAD patients. A risk prediction model was then developed based on these four MDGs to predict the prognosis of COAD patients. We also created a nomogram that incorporated risk scores, age, and TNM stage to promote a personalized prediction of OS in COAD patients. Compared with the traditional TNM staging system, our new nomogram was better at predicting the OS of COAD patients. In cell experiments, we confirmed that the mRNA expression levels of CLBN2 and TMEM220 were regulated by the methylation of their promoter regions. Moreover, immunohistochemistry showed that CBLN2 and TMEM220 were potential prognostic biomarkers for COAD patients. In summary, we have established a risk prediction model and nomogram that might be effectively utilized to promote the prediction of OS in COAD patients.

ABSTRACT

BACKGROUND/AIM: To evaluate quality of life (QoL) in women treated for ovarian tumors one year after laparotomy.

PATIENTS AND METHODS: The validated quality of life questionnaires (EORTC QLQ-C30 and QLQ-OV28) were sent to women who had undergone laparotomy due to ovarian tumors 12 months after surgery. The answers were analyzed and grouped according to the ovarian tumor histology (benign, borderline and cancer).

RESULTS: A total of 621 patients (87.5% out of 710) agreed to participate in the study. Ovarian cancer patients experienced statistically worse QoL one year after laparotomy in several analyzed parameters, including financial difficulties, compared to patients treated for benign and borderline tumors.

CONCLUSION: Women with ovarian cancer still need further cancer rehabilitation and support one year after diagnosis to improve their QoL. The novel finding was that ovarian cancer patients suffered from financial difficulties even in a free of charge health care system.

ABSTRACT

BACKGROUND/AIM: Little is known about the expression of L-type amino acid transporter 1 (LAT1) and 4F2hc in gastroenteropancreatic-neuroendocrine neoplasms (GEP-NENs). Hence, we conducted a study to verify the clinicopathological significance of LAT1 and 4F2hc.

PATIENTS AND METHODS: Tissues from 126 patients with GEP-NENs were collected between August 2007 and September 2019 at our institution. We evaluated LAT1 and 4F2hc expression by immunohistochemistry, and examined their clinical significance.

RESULTS: No statistically significant associations were observed between LAT1 expression and the different NENs. Expression of 4F2hc was significantly different between neuroendocrine tumour (NET)-G1, NET-G2, and NET-G3 (p=0.029), and was significantly associated with vascular invasion (p=0.044) and the Ki-67 index (p=0.042).

CONCLUSION: No association between LAT1 expression and malignant features in GEP-NENs was observed. However, an association between 4F2hc expression and the potential of malignancy in GEP-NENs was evident.

ABSTRACT

Climate change is increasing winter temperatures across the planet, altering snowmelt hydrology. This study addresses a gap in snow research in non-alpine areas by examining changes to snow and winter and spring streamflow across most of the eastern US using daily observations from weather stations and stream gages from water years 1960-2019. These daily data were aggregated across drainage basins and classified winters with similar temperatures; differences between winters and both seasonal and annual trends were statistically quantified. Winters were classified as “warm” or “cool” in each drainage basin relative to the 60-year mean; analysis of the data indicates that warm winters occur more frequently in recent decades from an average of 0.39 to 3.96 warm winters/decade from the 1960’s to the 2010’s respectively. Those classifications were then used to examine changes in snowpack over the same period, which shows that warmer winters have on average 50.1 cm less annual snowfall, a reduced maximum snowpack depth by 14.4 cm, and 34 more bare ground days. These changes correlate with shifts to higher winter streamflows as well as peak basin yields that are 0.02 cm lower and occur three days earlier in warm winters. In addition to altered soil moisture and stream ecosystem dynamics, these snow and streamflow changes may have negative infrastructure and economic implications including impacts to winter tourism and agriculture.

ABSTRACT

BACKGROUND/AIM: To date, multiple different surgical techniques have been established for hallux valgus surgery, with each technique having its unique advantages and limitations. The open distal chevron osteotomy is widely accepted, but increasing patient demands have led several minimally invasive (MIS) techniques to be described in recent years. The aim of this study was to compare outcomes after minimally invasive (MIS) distal chevron osteotomy and the minimally invasive Reverdin-Isham method.

PATIENTS AND METHODS: We assessed clinical and radiographic outcomes after MIS chevron osteotomy in 57 feet of 49 consecutive patients with a mean follow-up of 58.9 (range=39.0-85.4) months. Outcomes after MIS Reverdin-Isham osteotomy were analyzed by means of a systematic literature review with a minimum follow-up of 6 months.

RESULTS: Radiographic outcomes were significantly better in the MIS chevron cohort for intermetatarsal angle (p<0.001), hallux valgus angle and distal metacarpal articular angle (p<0.05). Concerning clinical outcomes, both methods provided comparable improvement.

CONCLUSION: MIS distal chevron osteotomy in mild to moderate hallux valgus deformity correction results in superior radiographic outcomes compared to the MIS Reverdin-Isham osteotomy. Sufficient correction of IMA cannot be achieved with the MIS Reverdin-Isham osteotomy.

ABSTRACT

The solar ultraviolet radiation (UVR) at national, provincial and county levels in Iran during 2005-2019 were determined based on Ozone Monitoring Instrument (OMI) dataset. The temporal (annual and monthly) trends and spatial distributions of the UVR in terms of erythemally weighted daily dose (EDD), erythemally weighted irradiance at local solar noon time (EDR), and UV index and the major factors influencing the spatiotemporal trends were analyzed. The population-weighted average values of EDD, EDR, and UV index in Iran were respectively 3631 J/m², 176.3 mW/m², 7.1 in 2005 and rose by 0.22% per year to 3744 J/m², 181.7 mW/m², and 7.3, respectively in 2019, but the annual trend was not statistically significant. The EDD in Iran during the study period exhibited the highest monthly average value in June (6339 J/m²) and the lowest one in December (1263 J/m²). The solar UVA/UVB ratios at the national level during 2005-2019 were considerably lower in summer. The EDD provincial average values in the study period were in the range of 2717 (Gilan) to 4424 J/m² (Fars). The spatiotemporal variations of the solar UVR parameters were well described by the linear models as a function of cloud optical thickness (COT), ozone column amount, surface albedo, latitude, and altitude (R² > 0.961, p value < 0.001) and the temporal changes of the solar UVR parameters were mainly caused by the COT. The results indicated that non-burning exposure to solar UVR in summer can be more efficient for vitamin D synthesis due to higher contribution of UVB in the solar UVR. The spatial distributions and temporal trends should be considered to determine the optimal duration, time and condition of exposure to the solar UVR for the public and occupational training and public health measures.

ABSTRACT

Women pregnant with a breech-presenting fetus at term are at an increased risk of adverse outcomes. Although the most common intervention is planned delivery by caesarean section, this is not always possible or desirable. Comparing alternative interventions is difficult due to heterogeneity in reported outcomes and their measurements. Additionally, the evidence, particularly for women in labour with a breech-presenting fetus, is very low quality, with several outcomes viewed as critical and important to decision-making not reported at all. There is a need to develop a core outcome set of minimum outcomes in all studies evaluating the effectiveness of interventions to improve outcomes associated with term breech birth (Breech-COS). Our objectives were to (1) identify outcomes currently reported in effectiveness studies of breech birth at term using a systematic review of the literature; (2) assess the methodological quality of outcome reporting in the included studies; and (3) engage with members of an established Patient and Public Involvement (PPI) group about the results, to help frame our understanding from the perspective of service users. We searched three databases (MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials) for all effectiveness studies associated with vaginal breech birth published in English between 2000 and 2020. Two reviewers independently screened and extracted the data. Outcomes were categorised into neonatal, maternal, features of labour, and long-term maternal and hierarchy of outcome classification (primary, secondary, part of composite, or undesignated). Frequency of reporting was calculated for each. An adapted methodological assessment was done for each study investigating whether primary and secondary objectives were clearly stated and defined. The results of the systematic review were then discussed with a PPI group to consider importance and relevance to service users. A total of 211 outcomes were extracted from 108 included studies, comprising of short (43) and long-term (39) neonatal, short (54) and long-term (39) maternal and features of labour (36) outcomes. The most frequently reported outcome in each category was: APGAR score at 5 min, developmental vulnerability/neurological morbidity, maternal mortality, urinary incontinence, and actual mode of birth respectively. Long-term outcomes were infrequently reported in the included studies, with outcomes for future pregnancies not reported at all, although these were each deemed important by service users. There was a lack of consensus in definition and measurement of outcomes, with only 36% of the included studies having clearly stated primary and secondary objectives. The observed heterogeneity in reported outcomes, lack of consensus in definition and measurement, as well as desire expressed by service users to have robust risk statistics for outcomes important to them highlights the need to develop a core outcome set for evaluating effectiveness studies of breech birth at term. A Breech-COS will enable useful synthesis of evidence and contribute to supported decision-making for women pregnant with a breech-presenting fetus at term.

ABSTRACT

OBJECTIVE: Short-term postoperative voiding dysfunction (POVD) is common in women undergoing surgery for pelvic organ prolapse. It results in increased catheter burden for patients and health services, and catheter-associated urinary tract infections (CAUTIs), thereby escalating the overall cost of treatment. Our aim was to determine the risk factors for voiding dysfunction following surgery for POP in our unit.

STUDY DESIGN: A retrospective case-control study conducted in a tertiary center in the U.K. The study cohort included all women who underwent surgery for pelvic organ prolapse between March 2017 and March 2019 and had a failed trial without catheter (TWOC). The control group comprised consecutive women on the surgical database who passed TWOC. Relevant data, including demographic details, past medical history, intraoperative and postoperative factors, were collected. We used the Chi-square test to calculate the statistical significance and multiple logistic regression analysis using SPSS software to identify the risk factors.

RESULTS: 286 surgeries were performed. After exclusion, 43 patients were included in each group. Baseline demographics were similar in both groups. The incidence of POVD was 15%, and none of our patients had long-term voiding problems. Logistic regression analysis identified five risk factors – advanced pelvic organ prolapse (OR = 2.654, p = 0.029), comorbidities (OR = 4.583, p = 0.019), preoperative anticholinergics and/or antidepressants (OR = 4.440, p = 0.004), sacrospinous hysteropexy/colpopexy (OR = 2.613, p = 0.041) and postoperative opioid use (OR = 3.529, p = 0.004).

CONCLUSION: We identified five risk factors to recognize the women who would benefit from advanced counseling and management plan following surgery for pelvic organ prolapse.
