Authors: Stern Benjamin , Chowers Itay , Ben-Eli Hadas 
Published: October 2023

Purpose This study investigates the relationship between pupil size during biometry examinations and the chord mu value in candidates for cataract surgery. Methods Retrospective analysis of ocular biometry measurements was performed on consecutive cataract surgery candidates above 50 years of age, examined between 2018 and 2020 at a single tertiary referral center. Statistical analysis assessed the association between pupil size and the chord mu value. The population was categorized into groups based on pupil size, and an analysis was conducted on the barycenter positions of the iris and pupil center for each group. Results The analysis included 2877 patients. A weak positive correlation was observed between the chord mu value and pupil size using Pearson's test ( r = 0.160, p < 0.01). Group stratification by pupil size indicated temporal and inferior shifts in pupil center barycenter as pupil size increased, reflecting asymmetrical pupil dilation during mydriasis. A moderate positive correlation between the chord mu value and chord alpha value was identified (Pearson's test, r = 0.641, p < 0.01). As expected, no correlation was found between chord alpha value and pupil size. Conclusions Chord mu values were higher in patients with mydriatic pupils, likely due to asymmetric pupil dilation and center displacement. Evaluating chord mu values requires considering pupil status and conducting biometry under standardized lighting to prevent misinterpretation caused by pharmacological dilation. This caution is crucial to avoid erroneously excluding eligible patients from multifocal IOL implants. Alternatively, the chord alpha value could serve as a more appropriate alternative in such scenarios.

Published: October 2023

Background: Multimorbidity is common in patients with stroke and is associated with increased medium- to long-term mortality, but its value for clinical decision-making and case-mix adjustment will depend on other factors, such as age, stroke severity, etiological subtype, prior disability, and vascular risk factors. Aims: In the absence of previous studies, we related multimorbidity to long-term post-stroke mortality with stratification by these factors. Methods: In patients ascertained in a population-based stroke incidence study (Oxford Vascular Study; 2002–2017), we related pre-stroke multimorbidity (weighted/unweighted Charlson comorbidity index (CCI)) to all-cause/vascular/non-vascular mortality (1/5/10 years) using regression models adjusted/stratified by age, sex, predicted early outcome (THRIVE score), stroke severity (NIH stroke scale (NIHSS)), etiology (Trial of Org 10172 in Acute Stroke Treatment (TOAST)), premorbid disability (modified Rankin Scale (mRS)), and non-CCI risk factors (hypertension, hyperlipidemia, atrial fibrillation, smoking, deprivation, anxiety/depression). Results: Among 2454 stroke patients (M/SD age: 74.1/13.9 years; 48.9% male; M/SD NIHSS: 5.7/7.0), 1375/56.0% had ⩾ 1 CCI comorbidity and 685/27.9% had ⩾ 2. After age/sex adjustment, multimorbidity (unweighted CCI ⩾ 2 vs 0) predicted (all ps < 0.001) mortality at 1 year (aHR = 1.57, 95% CI = 1.38–1.78), 5 years (aHR = 1.73, 95% CI = 1.53–1.96), and 10 years (aHR = 1.79, 95% CI = 1.58–2.03). Although multimorbidity was independently associated with premorbid disability (mRS > 2: aOR = 2.76, 2.13–3.60) and non-CCI risk factors (hypertension: 1.56, 1.25–1.95; hyperlipidemia: 2.58, 2.03–3.28; atrial fibrillation: 2.31; 1.78–2.98; smoking: 1.37, 1.01–1.86), it predicted death after adjustment for all measured confounders (10-year-aHR = 1.56, 1.37–1.78, p < 0.001), driven mainly by non-vascular death (aHR = 1.89, 1.55–2.29). Predictive value for 10-year all-cause death was greatest in patients with lower expected early mortality: lower THRIVE score (pint < 0.001), age < 75 years (aHR = 2.27, 1.71–3.00), NIHSS < 5 (1.84, 1.53–2.21), and lacunar stroke (3.56, 2.14–5.91). Results were similar using the weighted CCI. Conclusion: Pre-stroke multimorbidity is highly prevalent and is an independent predictor of death after stroke, supporting its inclusion in case-mix adjustment models and in informing decision-making by patients, families, and carers. Prediction in younger patients and after minor stroke, particularly for non-vascular death, suggests potential clinical utility in targeting interventions that require survival for 5–10 years to achieve a favorable risk/benefit ratio.

Prevalence and determinants of chronic pain and persistent opioid use after surgery: A review of systematic reviews
Authors: Bansal Neetu , Ang Sheanne , Chen Li-Chia 
Published: October 2023

Background Chronic post-surgical pain (CPSP) and persistent post-operative opioid use (PPOU) are inconsistently defined in published literature. This review comprehensively summarised their definitions, prevalence and determinants from existing systematic reviews or meta-analyses. Methods Systematic reviews or meta-analyses evaluating the prevalence of CPSP and PPOU in adults after surgeries were retrieved from an electronic database search applying structured search strategies in PubMed, MEDLINE, Embase, CINAHL Plus and Cochrane Database of Systematic Reviews from inception to 31 December 2022. Two reviewers selected systematic reviews, extracted data regarding the definition, prevalence and risk factors of CPSP and PPOU and assessed the quality using the AMSTAR 2 tool. Results The study identified 6936 records related to chronic pain and persistent opioid use in patients after surgery, of which 24 articles were identified for full-text review. Eighteen systematic reviews were included in this umbrella review, of which five systematic reviews assessed chronic pain in patients who had undergone a surgical procedure, and 13 reviews assessed persistent opioid use after surgery. Despite considerable variations in patient characteristics (from age ≥18 years), types of surgeries, follow-up duration and the definitions of measures, most reviews were of medium to good quality (fulfilled 9-11/16 AMSTAR 2 criteria). The prevalence of CPSP and PPOU, commonly synthesised at 3, 6 or 12 months after surgeries, varied from 5%–58% and 2%–65%, respectively, despite various terminologies, definitions and timing of measures and associated determinants. The prevalence of neuropathic pain in CPSP was obtainable for four surgeries, with 9%–74%. Conclusion To inform future practice and policy to optimise pain management and opioid safety, consensus on standardising measurements and further studies assessing risk factors associated with CPSP, PPOU and adverse outcomes are needed.
Patient Perspective on Adherence to Reflux Lifestyle Modifications: A Qualitative Study
Authors: Chouhdry Hira , Villwock Jennifer 
Published: October 2023

Objective: Acid reflux disease is a common condition with recurrent symptoms affecting the quality of life of many Americans. Lifestyle/dietary modification is critical for management of acid reflux disease. Adherence to these recommendations is variable. The purpose of this study was to better understand the experience of patients with reflux disease (GERD/LPR) and explore factors that impact the integration of lifestyle modifications into their daily lives. Methods: Patient with diagnoses of GERD and/or LPR were recruited from an outpatient laryngology clinic and completed the Reflux Symptom Index (RSI) and a semi-structured interview. Interviews were transcribed and underwent thematic analysis. Results: Twenty-three patients—mean age and RSI of 61 and 16.1 respectively—were recruited. Four main themes emerged: (1) Care team interaction—focus and quality of physician counseling, useful educational handouts, dietician/nutritionist counseling; (2) Motivation to change—impact on symptom severity, avoiding undesired interventions, and poor health outcomes; (3) Implementing lifestyle changes; and (4) Impact of disease on patient. No patient had seen a dietician. Patients who experienced dietary counseling for other conditions felt reflux-specific counseling with a dietician would be beneficial. While patients found educational material on diet to be helpful, lists of foods to avoid were discouraging; providing a positive list of preferred foods may be more helpful. Conclusion: Lifestyle modification counseling should incorporate multiple aspects of the patient experience. Patients desire information regarding medication side effects. Educational handouts should include prioritized list of recommended dietary restrictions and acceptable/alternative food options. Referral for dedicated dietician counseling can also be considered to increase understanding of the importance of, and adherence to, lifestyle modification.

Published: October 2023

Background A substantial increase in the incidence of immediate release fentanyl (IRF) use was reported in Spain from 2012 to 2017. Purpose This study aimed to investigate the relationship dynamically with cancer incidence in order to provide empirical evidence of inappropriate use of IRF with respect to the pathology. Research design A vector autoregresive (VAR) model was constructed using data from a nationwide electronic healthcare record database in primary care in Spain (BIFAP) according to the following step procedure: (1) split data into training data for modelling and test for validation (2) assessing for time series stationarity; (3) selecting lag-length; (4) building the VAR model; (5) assessing residual autocorrelation; (6) checking stability of the VAR system; (7) evaluating Granger causality; (8) impulse response analysis and forecast error variance decomposition (9) prediction performance with validation data. Results The analysis showed a strong and linear correlation between IRF and cancer (Pearson correlation coefficient: 0.594 (95% CI: 0.420–0.726). Two VAR models, VAR (2) and VAR (11) were selected and compared. All tests performed for both models satisfied assumptions for stability, predictability and accuracy. Granger causality revealed cancer incidence is a good predictor for IRF use. VAR (2) seemed to be slightly more accurate, according to the RMSE of the test data. Conclusions This study demonstrates that using a robust and structured VAR modelling approach, is able to estimate dynamics associations, involving IRF use and cancer incidence.

Abstract
Objectives
The purpose of this study was to evaluate possible factors that might be accompanied by high level of human monkey pox (HMPX) knowledge and to explain the relationship between HMPX knowledge and Beliefs regarding emerging viral infections.

Study design
A descriptive cross-sectional study was conducted for the implementation of this study.

Methods
Study was conducted at two general hospitals in Mansoura City (Old General Hospital and International Hospital) El Dakahlia Governorate among 620 healthcare workers (HCWs) using a self-managed questionnaire for 1 week (1 to 7 January 2023). The questionnaire has items adapted from the previously published literature to assess HMPX knowledge and Beliefs regarding emerging viral infections.

Results
The mean age of the study sample was 27.97 years and most of them were female (86.1%). Physicians and other HCWs (nurses, laboratory technicians, radiographer technicians, and pharmacists) had significantly different levels of knowledge of monkeypox for the majority of the questions. A higher belief was found among two items: viruses are biological weapons manufactured by the superpowers to take global control and the government is misleading the public about the cause of the virus.

Conclusion
This study discovered lower levels of knowledge of HMPX among HCWs in Egypt. Beliefs about emerging viral infections were widespread, and future research should look into their potential negative impact on health behavior.
Mindfulness interventions for craving reduction in substance use disorders and behavioral addictions: systematic review and meta-analysis of randomized controlled trials
Authors: Demina Anastasia , Petit Benjamin , Meille Vincent , Trojak Benoit 
Published: October 2023

Abstract
Background
High-quality evidence is still required to affirm the efficacy of mindfulness-based interventions (MBIs) in craving reduction. MBIs may be particularly appropriate for this purpose given the neurobiological mechanisms of addiction with automatic behavior in response to the negative affect. In this systematic review and meta-analysis, we aimed to study the efficacy of MBIs in craving reduction and to synthetize the newly published data.

Methods
We searched four databases and three clinical trial registries for randomized controlled trials (RCTs) up to August 2023, including studies with MBIs in all types of substance use disorders or behavioral addictions. We chose as our outcome of interest the change from the baseline of craving measures at posttreatment. Standardized mean difference was used as an effect size estimator.

Results
We included 17 RCTs with 1228 participants. The overall effect size was estimated at -0.70 (95% CI -1.15, -0.26) in favor of MBIs.

Conclusion
Due to the high inconsistency (I2 = 92%), we were unable to conclude that there is a medium to large effect size. Overall risk of bias was high for most studies, and the GRADE approach detected a low quality of evidence. Previous clinical and fundamental research suggest that MBIs have a promising potential in addiction medicine. However, further investigation of whether MBIs effectively reduce craving is needed, and innovative solutions for resolving methodological limitations in MBI research are warranted.

Rural health dialogue for the sustainability of help-seeking behaviors among older patients: grounded theory approach
Authors: Ohta Ryuichi , Sano Chiaki 
Published: October 2023

Abstract
Background
Help-seeking behaviors (HSBs) are essential for disease prevention and health promotion. Dialogues with peers and medical professionals can improve HSBs, both qualitatively and quantitatively. Rural communities lacking healthcare resources require effective HSBs for healthcare sustainability. The current study aimed to investigate the effect of health dialogues between medical professionals and rural citizens on their HSBs.

Methods
All procedures complied with the Declaration of Helsinki and its subsequent amendments. The Unnan City Hospital Clinical Ethics Committee approved the study protocol (No. 20,220,002). A grounded theory approach was employed for the health dialogue participants in rural communities. Health dialogues with family physicians were conducted once a month at rural community centers. The dialogues and focus group interviews were recorded and coded to investigate changes in participants’ perceptions and behaviors regarding HSBs.

Results
Twenty-one dialogues were conducted in two rural community centers, with a total of 112 participants. The average age of the participants was 70.2 years (standard deviation = 5.4), with 24% being males. Analysis of the grounded theory approach revealed four themes, namely joy-driven dialogue driving the realization of HSBs, reflection on personal HSBs through learning from others, revising HSBs based on rural social resources, and familiarity with physicians, hence motivating safe and secure HSBs.

Conclusions
Mitigation of barriers between citizens and medical professionals and improvement of psychological safety in communities can drive effective HSBs in rural communities.

Authors: Zhu Xiaolin , He Na , Tong Le , Gu Zhi Han , Li Hong 
Published: October 2023

Abstract
Background
Few studies have analyzed the clinical characteristics and adverse factors affecting prognosis in older patients with tuberculous meningitis (TBM). This study aimed to compare the clinical characteristics of TBM in older patients with those in younger and middle-aged patients.

Methods
This single-center retrospective study extracted data on the clinical features, cerebrospinal fluid changes, laboratory results, imaging features, and outcomes of patients with TBM from patient medical records and compared the findings in older patients (aged 60 years and older) with those of younger and middle-aged patients (aged 18–59 years).

Results
The study included 197 patients with TBM, comprising 21 older patients aged 60–76 years at onset, and 176 younger and middle-aged patients aged 18–59 years at onset. Fever was common in both older (81%) and younger and middle-aged patients (79%). Compared with younger and middle-aged patients, older patients were more likely to have changes in awareness levels (67% vs. 40%), peripheral nerve dysfunction (57% vs. 29%), changes in cognitive function (48% vs. 20%), and focal seizures (33% vs. 6%), and less likely to have headache (71% vs. 93%), neck stiffness on meningeal stimulation (38% vs. 62%), and vomiting (47% vs. 68%). The Medical Research Council staging on admission of older patients was stage II (52%) and stage III (38%), whereas most younger and middle-aged patients had stage I (33%) and stage II (55%) disease. Neurological function evaluated on the 28th day of hospitalization was more likely to show poor prognosis in older patients than in younger and middle-aged patients (76% vs. 25%). Older patients had significantly higher red blood cell counts and blood glucose levels, and significantly lower serum albumin and sodium levels than those in younger and middle-aged patients. The cerebrospinal fluid protein levels, nucleated cell counts, glucose levels, and chloride levels did not differ significantly by age.

Conclusion
In patients with TBM, older patients have more severe clinical manifestations, a higher incidence of hydrocephalus and cerebral infarction, and longer hospital stays than younger and middle-aged patients. Older patients thus require special clinical attention.

Abstract
Background
The effectiveness of Deep Brain Stimulation (DBS) therapy for Parkinson’s disease can be limited by side-effects caused by electrical current spillover into structures adjacent to the target area. The objective of the STEEred versus RING-mode DBS for Parkinson’s disease (STEERING) study is to investigate if directional DBS for Parkinson’s disease results in a better clinical outcome when compared to ring-mode DBS.

Methods
The STEERING study is a prospective multi-centre double-blind randomised crossover trial. Inclusion criteria are Parkinson’s disease, subthalamic nucleus DBS in a ‘classic’ ring-mode setting for a minimum of six months, and optimal ring-mode settings have been established. Participants are categorised into one of two subgroups according to their clinical response to the ring-mode settings as ‘responders’ (i.e., patient with a satisfactory effect of ring-mode DBS) or ‘non-responder’ (i.e., patient with a non-satisfactory effect of ring-mode DBS). A total of 64 responders and 38 non-responders will be included (total 102 patients). After an optimisation period in which an optimal directional setting is found, participants are randomised to first receive ring-mode DBS for 56 days (range 28–66) followed by directional DBS for 56 days (28–66) or vice-versa. The primary outcome is the difference between ring-mode DBS and directional DBS settings on the Movement Disorders Society Unified Parkinson’s Disease Rating Scale – Motor Evaluation (MDS-UPDRS-ME) in the off-medication state. Secondary outcome measures consist of MDS-UPDRS-ME in the on-medication state, MDS-UPDRS Activities of Daily Living, MDS-UPDRS Motor Complications–Dyskinesia, disease related quality of life measured with the Parkinson’s Disease Questionnaire 39, stimulation-induced side-effects, antiparkinsonian medication use, and DBS-parameters. Participants’ therapy preference is measured at the end of the study. Outcomes will be analysed for both responder and non-responder groups, as well as for both groups pooled together.

Discussion
The STEERING trial will provide insights into whether or not directional DBS should be standardly used in all Parkinson’s disease DBS patients or if directional DBS should only be used in a case-based approach.

Trial registration
This trial was registered on the Netherlands Trial Register, as trial NL6508 (NTR6696) on June 23, 2017.

Published: October 2023

Abstract
Background
To evaluate the improvement of evaluation accuracy of cervical maturity for Chinese women with labor induction by adding objective ultrasound data and machine learning models to the existing traditional Bishop method.

Methods
The machine learning model was trained and tested using 101 sets of data from pregnant women who were examined and had their delivery in Peking University Third Hospital in between December 2019 and January 2021. The inputs of the model included cervical length, Bishop score, angle, age, induced labor time, measurement time (MT), measurement time to induced labor time (MTILT), method of induced labor, and primiparity/multiparity. The output of the model is the predicted time from induced labor to labor. Our experiments analyzed the effectiveness of three machine learning models: XGBoost, CatBoost and RF(Random forest). we consider the root-mean-squared error (RMSE) and the mean absolute error (MAE) as the criterion to evaluate the accuracy of the model. Difference was compared using t-test on RMSE between the machine learning model and the traditional Bishop score.

Results
The mean absolute error of the prediction result of Bishop scoring method was 19.45 h, and the RMSE was 24.56 h. The prediction error of machine learning model was lower than the Bishop score method. Among the three machine learning models, the MAE of the model with the best prediction effect was 13.49 h and the RMSE was 16.98 h. After selection of feature the prediction accuracy of the XGBoost and RF was slightly improved. After feature selection and artificially removing the Bishop score, the prediction accuracy of the three models decreased slightly. The best model was XGBoost (p = 0.0017). The p-value of the other two models was < 0.01.

Conclusion
In the evaluation of cervical maturity, the results of machine learning method are more objective and significantly accurate compared with the traditional Bishop scoring method. The machine learning method is a better predictor of cervical maturity than the traditional Bishop method.
