Alteration of brain network centrality in CTN patients after a single triggering pain.

Objective: The central nervous system may also be involved in the pathogenesis of classical trigeminal neuralgia (CTN). The present study aimed to explore the characteristics of static degree centrality (sDC) and dynamic degree centrality (dDC) at multiple time points after a single triggering pain in CTN patients. Materials and methods: A total of 43 CTN patients underwent resting-state function magnetic resonance imaging (rs-fMRI) before triggering pain (baseline), within 5 s after triggering pain (triggering-5 s), and 30 min after triggering pain (triggering-30 min). Voxel-based degree centrality (DC) was used to assess the alteration of functional connection at different time points. Results: The sDC values of the right caudate nucleus, fusiform gyrus, middle temporal gyrus, middle frontal gyrus, and orbital part were decreased in triggering-5 s and increased in triggering-30 min. The sDC value of the bilateral superior frontal gyrus were increased in triggering-5 s and decreased in triggering-30 min. The dDC value of the right lingual gyrus was gradually increased in triggering-5 s and triggering-30 min. Conclusion: Both the sDC and dDC values were changed after triggering pain, and the brain regions were different between the two parameters, which supplemented each other. The brain regions which the sDC and dDC values were changing reflect the global brain function of CTN patients, and provides a basis for further exploration of the central mechanism of CTN.

Multidata Analysis Based on an Artificial Neural Network Model for Long-Term Pain Outcome and Key Predictors of Microvascular Decompression in Trigeminal Neuralgia.

OBJECTIVE: To investigate use of multidata analysis based on an artificial neural network (ANN) to predict long-term pain outcomes after microvascular decompression (MVD) in patients with trigeminal neuralgia (TN) and to explore key predictors. METHODS: Perioperative and long-term follow-up multidata of 1041 patients with TN who received MVD surgery at Hangzhou First People's Hospital from March 2013 to May 2018 were collected to construct an ANN model for prediction. The prediction results were compared with the actual follow-up outcomes, and the variables in each input layer were changed to test the effectiveness of ANN and explore the factors that had the greatest impact on prediction accuracy. RESULTS: The ANN model could predict the long-term pain outcomes after MVD in patients with TN with an accuracy rate of 95.2% and area under the curve of 0.862. Four factors contributed the most to the predictive performance of the ANN: whether the neurovascular offending site of the trigeminal nerve corresponded the region of facial pain, immediate postoperative pain remission after MVD, degree of nerve compression by culprit vessels, and the type of culprit vessels. After these factors were sequentially removed, the accuracy of the ANN model decreased to 74.5%, 78.6%, 87.2%, and 90.1%, while the area under the curve was 0.705, 0.761, 0.793, and 0.810. CONCLUSIONS: The ANN model, constructed using multiple data, predicted long-term pain prognosis after MVD in patients with TN objectively and accurately. The model was able to assess the importance of each factor in the prediction of pain outcome.

Death anxiety among advanced cancer patients: a cross-sectional survey.

PURPOSE: This study aimed to investigate death anxiety in advanced cancer patients and identify associated factors in the context of Chinese culture. METHODS: Participants (N = 270) with advanced cancer in a tertiary cancer hospital completed anonymous questionnaire surveys. Measures included the Chinese version of a Likert-type Templer-Death Anxiety Scale, Rosenberg's Self-esteem Scale, Medical Coping Modes Questionnaire, the Social Support Rating Scale, and Connor-Davidson Resilience Scale. Data were analyzed in SPSS using descriptive statistics, Student's t test, Pearson correlation test, and linear regression. RESULTS: Respondents returned 252 (93.33%) of the 270 questionnaires. The total CL-TDAS score was 39.56 ± 10.20. The top three items were "I fear dying a painful death" (3.59 ± 1.41), "I often think about how shortly life really is" (3.11 ± 1.33), and "1 am not particularly afraid of getting cancer" (3.09 ± 1.35). Associated factors of death anxiety (R2 = .333, F = 15.756, p < .001) were the medical coping mode (resignation, confronce), self-esteem, the participants' adult children, the patient-primary caregivers' relationship, resilience, and the level of activity of daily living. CONCLUSIONS: Our results demonstrate high levels of death anxiety in advanced cancer patients. Generally, patients with adult children, high self-esteem and resilience had low death anxiety. Conversely, patients with low levels of activity of daily living and high coping mode (resignation, confrontation) reported high death anxiety. We determined that associated factors contributed to reduce death anxiety. Social interventions are recommended to improve the end-of-life transition for patients and caregivers.

Risk factors of senile degenerative valvular heart disease / 中华老年医学杂志

Objective:To explore the clinical characteristics and related risk factors of senile degenerative valvular heart disease(SDHVD), and to provide clinical basis for early prevention intervention of SDHVD.Methods:Clinical data of 1568 elderly patients ≥60 years old hospitalized in our hospital from January 2022 to June 2022 were collected to compare the clinical characteristics and analyze the risk factors of patients in the degenerative heart valve disease group and the non-degenerative heart valve disease group.Results:Age(per 10-year increase)( OR=2.107, 95% CI=1.518-2.924), blood calcium( OR=8.934, 95% CI=2.023-39.447), total cholesterol( OR=1.167, 95% CI=1.044-1.304), female( OR=2.098, 95% CI=1.305-3.374), and reduced mean platelet volume(MPV)( OR=0.818, 95% CI=0.682-0.981)were independent risk factors for the development of SDHVD( P<0.05).Post hoc two-by-two comparisons showed that different degrees of calcification were associated with age( P<0.05); apoA, UA, P, and FT3 were statistically significant in the no-calcification group compared with the control group( P<0.05); E/e′, PASP, and NT-ProBNP were statistically significant in the moderate calcification group compared with the control group( P<0.05); TC was statistically significant in the no-calcification and mild calcification groups compared with the control group There was statistical significance( P<0.05)compared with the control group. Conclusions:Age, blood calcium, total cholesterol, female, and reduced MPV are independent risk factors for SDHVD.

Modified sacrospinous ligament fixation in treatment of pelvic organ prolapse / 中华内分泌外科杂志

Objective:To study the clinical effect of sacrospinous ligament fixation (SSLF) and traditional vaginal hysterectomy on pelvic organ prolapse (POP) .Methods:A retrospective analysis was performed on 68 patients with POP of degree II-IV admittedl from Jan. 2017 to Dec. 2019. Among them, 33 patients were treated with SSLF (observation group) and 35 patients were treated with vaginal total hysterectomy (control group). Intraoperative blood loss, operative time, postoperative indwelling catheter and average length of hospital stay were compared between the two groups. The patients were followed up for 6 months, and the scores of pelvic floor dysfunction questionnaire-20 (PFDI-20) and sexual quality questionnaire -12 (PISQ-12) were used to evaluate the subjective satisfaction degree of postoperative recovery.Results:In the observation group, the intraoperative blood loss (173.94±52.14) ml, postoperative indurating catheter time (2.72±0.45) d and average length of hospital stay (7.09±0.63) d were observed. There were statistically significant differences in intraoperative blood loss (228.86±53.40) ml, postoperative induration time (4.54±0.61) d and mean hospital stay (9.22±0.81) d in the control group ( P<0.05). There was no significant difference in the operation time between the observation group (99.57±9.50) min and the control group (101.06±8.64) min, ( P>0.05). The improvement of PFDI-20 and PISQ-12 in both groups was significant before and after treatment. The PISQ-12 score of the observation group was higher than that of the control group 6 months after surgery, and the difference was statistically significant ( P <0. 05). There was no significant difference in PFDI-20 score between the two groups ( P>0.05). There was statistical significance in the positions of pop-Q indicators in the two surgical methods ( P < 0.05) . Conclusions:SSLF with uterus preservation and total vaginal hysterectomy are both effective in treatment of moderate and severe POP. However, SSLF with uterus preservation has less intraoperative blood loss, and the postoperative recovery is significantly better than that with total vaginal hysterectomy. In addition, it satisfies patients’ desire to preserve uterus, improves the postoperative sexual life quality, which is worthy of promotion.

Vulnerability and burden of all-cause mortality associated with particulate air pollution increased during COVID-19 pandemic: a nationwide observed study in Italy

BackgroundLimited evidence is available on the health effects of particulate matter (i.e. PM2.5, particulate matter with an aerodynamic diameter < 2.5m; PM10, < 10m; PM2.5-10, 2.5-10m) during the pandemic of COVID-19 in Italy. ObjectivesTo examine the associations between all-cause mortality and daily PM2.5, PM2.5-10, and PM10 in the pandemic period, and compare them to the normal periods (2015-2019) in Italy. MethodsWe collected daily data regarding all-cause (stratified by age and gender), and PM2.5, PM2.5-10, and PM10 for 107 Italian provinces from 1, January 2015 to 31, May 2020. A time-stratified case-cross design with the distributed lag non-linear model was used to examine the association between PM and all-cause mortality during the first three months of the COVID-19 outbreak (March to May in 2020) and the same months in 2015-2019. We also compared the counts and fractions of death attributable to PM in two periods. ResultsOverall, Italy saw an increase in daily death counts while slight decreases in PM concentrations in 2020 pandemic period compared to same months of 2015-2019. Mortality effects were significant in lag 0-3 days for PM2.5, lag 0-2 for PM10, and lag 0-1 for PM2.5-10. Each 10 {micro}g/m3 increase in PM was associated much higher increase in daily all-cause mortality during 2020 pandemic period compared to the same months during 2015-2019 [increased mortality rate: 7.24 % (95%CI: 4.84%, 9.70%) versus 1.69% (95%CI: 1.12%, 2.25%) for PM2.5; 3.45 % (95%C: 2.58%, 4.34%) versus 1.11% (95%CI: 0.79%, 1.42%) for PM10, 4.25% (95%CI: 2.99%, 5.52%) versus 1.76% (95%CI: 1.14%, 2.38%) for PM2.5-10]. The counts and fractions of deaths attributable to PM were higher in 2020 than the normal periods for PM2.5 (attributable death counts: 20,062 in 2020 versus 3,927 per year in 2015-2019; attributable fractions: 10.2% versus 2.4%), PM10 (15,112 versus 3,999; 7.7% versus 2.5%), and PM2.5-10 (7,193 versus 2303; 3.7% versus 1.4%). ConclusionsCOVID-19 pandemic increased the vulnerability and excess cases of all-cause mortality associated with short-term exposure to PM2.5, PM2.5-10 and PM10 in Italy, despite a decline in air pollution level. This suggests using historical PM-mortality association to calculate health benefits associated with reduction in PMs has big uncertainties.

COVID-19 pandemic increased the magnitude of mortality risks associated with cold temperature in Italy: A nationwide time-stratified case-crossover study

Abstract Backgrounds: The coronavirus disease 2019 (COVID-19) pandemic and some containment measures have changed many people lives and behaviours. Whether the pandemic could change the association between cold temperature and mortality remains unknown. Objectives: We aimed to assess whether the association between cold temperature and all-cause mortality in the pandemic period has changed compared to non-COVID-19 period (2015-2019) in Italy. Methods: We collected daily all-cause mortality data and meteorological data for 107 Italian provinces from 1, January 2015 to 31, May 2020. A time-stratified case-crossover design with the distributed lag non-linear model was used to examine the association between cold temperature and all-cause mortality during the first three months (from March to May in 2020) of the COVID-19 outbreak and the same months in 2015-2019. Results: The relative risk (RR) of all-cause mortality at extreme cold temperature (2.5th percentile of temperature at 3 {degrees}C) in comparison with the minimum mortality temperature (24 {degrees}C) was 4.75 [95% confidence interval (CI): 3.90-5.79] in the pandemic period, which is more than triple higher than RR [1.41 (95%CI: 1.33-1.50)] in the same months during 2015-2019. The shift in cold-mortality association was particularly significant for people aged 65-74 years [RR (95%CI): 5.98 (3.78-9.46) in 2020 versus 1.29 (1.10-1.51) in 2015-2019], 75-84 years [5.25 (3.79-7.26) versus 1.40 (1.25-1.56)], and [≥] 85 years [5.03 (3.90-6.51) versus 1.52 (1.39-1.66)], but not significant for those aged 0-64 years [1.95 (1.17-3.24) versus 1.24 (1.05-1.48)]. Conclusion: The findings suggest that the COVID-19 pandemic enhanced the risk of cold temperature on mortality in Italy, particularly among the elderly people. Further studies are warranted to understand the exact mechanism when detailed data are available.
