Published: May 2022

Abstract
Background
Evaluate outcomes and identify prognostic factors in congenital aniridia.

Methods
Retrospective interventional case series of patients with congenital aniridia treated between 2012–2020. Ocular examination and surgical details were collected. Surgical failure was defined as disease progression or need for additional surgery for same/related indication. Kaplan–Meier survival curves, Wilcoxon test, and univariate and multivariate linear regression analyses were performed.

Results
Ninety-four patients with congenital aniridia presented at median 19.0 years. Two-thirds of patients underwent ≥ 1intraocular surgery, with average of 1.7 ± 2.3 surgeries/eye. At final follow-up (median 4.0 years), 45% of eyes had undergone lensectomy. Aphakic eyes showed worse visual acuity (VA) than phakic or pseudophakic eyes. Glaucoma affected 52% of eyes, of which half required IOP-lowering surgery. Glaucoma drainage devices showed the highest success rate (71%) at 14.2 ± 15.4 years of follow-up. Keratopathy affected 65% of eyes and one-third underwent corneal surgery. Keratoprosthesis had the longest survival rates at 10-years (64% with 95% CI [32,84]). LogMAR VA at presentation and final follow-up were not statistically different. Half of patients were legally blind at final follow-up. Final VA was associated with presenting VA, glaucoma diagnosis, and cataract or keratopathy at presentation. Penetrating keratoplasty and keratoprosthesis implantation correlated with worse BCVA.

Conclusions
Most aniridic patients in this large US-based cohort underwent at least 1 intraocular surgery. Cataract, glaucoma, and keratopathy were associated with worse VA and are important prognostic factors to consider when managing congenital aniridia.

Published: May 2022

Abstract
Background
Medical and nursing students’ attitudes toward mental disorders have a large impact on their working intentions in mental health settings and patients’ health outcomes. However, there are few studies about the stigma toward mental disorders among medical and nursing students in China.

Methods
In this cross-sectional study, a total of 838 medical and nursing students completed questionnaires on their sociodemographic characteristics and familiarity with people diagnosed with mental disorders as well as the Community Attitudes toward Mental Illness Scale (CAMI). The stigma was compared between medical students and nursing students by ANOVA. A multiple logistic regression model was built to explore the relationships among sociodemographic characteristics, familiarity with mental disorders and stigma.

Results
The total mean score of the CAMI was 137.61 (SD = 15.63). The score for authoritarianism (M = 33.33, SD = 3.62) was the lowest score of the four subscales. Medical students showed more positive attitudes toward mental disorders than nursing students. However, after controlling the co-variables, the difference disappeared. Stigma was significantly associated with students’ education, area of residence, marital status, economic status, history of mental disorders and familiarity with mental disorders.

Conclusions
Medical and nursing students show a negative attitude toward mental illness to a certain degree, especially regarding the view that people with mental disorders are inferior. Higher education level, residence in urban areas, single marital status, better economic status, and better familiarity with mental disorders may be related to less stigma among medical and nursing students.
Factors and at-risk group associated with hypertension self-management patterns among people with physical disabilities: a latent class analysis
Authors: Nam Hye Jin , Yoon Ju Young 
Published: May 2022

Abstract
Background
People with disabilities are vulnerable to chronic diseases such as hypertension. In South Korea, over half of the population living with a physical disability suffer from hypertension. Understanding the typology of hypertension self-management patterns will assist with behavioural interventions for people with physical disabilities. Thus, this study aims to identify the typology of hypertension self-management behavioural patterns, the factors associated with the latent classes, and to recognise potential at-risk populations by comparing potential health outcomes among hypertensive adults with physical disabilities.

Methods
Data of 1551 participants were extracted from the 2017 National Survey of Disabled Persons. Latent classes were analysed using five indicators of self-management: smoking, alcohol consumption, physical activity, diet, and weight control. Determinants of self-management patterns, such as general characteristics, health-related factors, and social relationships, were identified using multinomial logistic regression. Further, health measures, such as health profile, psychological health, and patient experience, were compared.

Results
The following three latent classes were identified: “high self-management” group (40.8%), “harmful habitual behaviour” group (20.6%), and “inactive behaviour” group (38.6%). Compared with the high self-management group, the predictors of belonging to the harmful habitual behaviour group were being male, young, and single. Being female, employed, severely disabled, dependent, and unsatisfied with friendships were predictors of the inactive behaviour group. Those in the inactive behaviour group had a poor health-related quality of life, poor subjective health, depression, and unmet medical needs.

Conclusions
This study provides evidence that there are mutually exclusive subgroups of patients with hypertension regarding self-management patterns, identifies an array of predictive factors in each latent class membership, and distinguishes a high-risk group by comparing the health measures among patients with hypertension with physical disabilities. Analysing subgroups may assist in identifying and meeting the diverse needs of self-management support in hypertensive patients with physical disabilities.

Authors: Wang Jun , Xu Meiqing , Zhang Chuankai , Wei Dazhong 
Published: May 2022

Abstract
Objective
To investigate the efficacy and safety of simultaneous subxiphoid single-port thoracoscopic resection of bilateral lung lesions.

Methods
This retrospective study analyzed the clinical data of 72 patients who underwent resection of bilateral lung lesions at the Department of Thoracic Surgery in the First Affiliated Hospital of University of Science and Technology of China between August 2020 and January 2022. Surgery-related parameters were compared between patients who underwent subxiphoid single-port thoracoscopy (subxiphoid group, 36 patients) and patients who underwent intercostal single-port thoracoscopy (intercostal group, 36 patients).

Results
Compared to the intercostal group, the subxiphoid group exhibited significantly better postoperative catheterization time (P = 0.013), postoperative thoracic drainage, postoperative visual analog scale pain scores at 24 and 48 h, and incision pain and numbness at 1 and 3 months after surgery (all P < 0.05). There were no significant differences in operation time, intraoperative blood loss, or postoperative complications between the two groups (all P > 0.05). There were no cases of perioperative mortality, conversion to thoracotomy, or serious complications in either group.

Conclusion
Subxiphoid single-port thoracoscopic surgery for simultaneous resection of bilateral lung lesions is safe and effective, reduces postoperative acute and chronic pain, decreases trauma, allows faster recovery, and is more consistent with the concept of minimally invasive surgery than bilateral intercostal single-port thoracoscopy. Thus, this subxiphoid single-port thoracoscopic surgery approach should be considered for clinical application.

AbstractBackgroundThis study aimed to assess the effect of different commercially used calcium hydroxide [Ca(OH)2], the mixture of Ca(OH)2 + silver nanoparticles (AgNPs), and other intracanal medicaments on dislodgement resistance of mineral trioxide aggregate (MTA) to root canal dentin in short- and long-term application.MethodsForty-six human single-rooted maxillary teeth were sectioned horizontally at mid-root into 1 mm thick slices. The lumen of the slices was standardized using #2–#5 Gates Glidden drills to a standard diameter of 1.3 mm in all samples. After smear layer removal, the samples were randomly divided into eight groups (n = 20) and treated with the following medicaments; Ca(OH)2paste, Calcipex, Metapex, chlorhexidine (CHX), Ca(OH)2/CHX paste, Ca(OH)2/AgNPs, triple antibiotic paste and control group (normal saline). The samples were then incubated at 37 °C with 100% humidity for 1 week. Next, half of the teeth in each group (n = 10) were removed from the incubator and washed in an ultrasonic bath. ProRoot MTA was placed in the canal lumen and the samples were incubated at 37 °C and 100% humidity for 48 h to allow complete setting of MTA. The remaining half in each group (n = 10) was subjected to the same process after 1 month of application of medicaments. The dislodgement resistance of MTA to root dentin was measured. The data were analysed using two-way ANOVA and Tukey’s post hoc test.ResultsNo significant difference was noted in dislodgement resistance of samples after 1 week and 1 month in any group (P > 0.05). The only significant difference was noted between the control and CHX groups and the higher dislodgement resistance was recorded in the CHX group (P = 0.006). No other significant differences were noted between the groups (P > 0.05).ConclusionDuration of application and the type of intracanal medicament do not affect the dislodgement resistance of MTA to root dentin. Although there was no statistically significant difference in the dislodgment resistance of MTA between the medicaments, CHX had a promising effect.

Abstract
Background
Unplanned reoperation (UR) after radical surgery for oral cancer (OC) is a health threat for the patients. The aim of the study was to identify the incidence of and risk factors for unplanned reoperation following oral cancer radical surgery, and to explore a potential role for long-term survival.

Methods
The present study followed a retrospective study design. Univariate and multivariate analyses were used to identify risk factors for demographic and clinical characteristics of patients. Survival analysis was performed by the Kaplan–Meier method. The data was analyzed statistically between November and December 2021.

Results
The incidence of UR was 15.7%. The primary cause of UR was reconstructed flap complications. Multivariate logistic regression analyses revealed that diabetes, tumor size, type of reconstruction, and nodal metastasis were independent risk factors for UR. Patients undergoing UR had a longer hospitalization, more post-operative complications, and a higher mortality compared with the non-UR group. UR is negatively correlated with the cancer-specific survival rate of patients (Log-rank test, P = 0.024).

Conclusion
Diabetes, tumor size, pedicled flap reconstruction and cervical nodal metastasis (N2) as independent risk factors for UR was discovered. UR was positively correlated with perioperative complications prolong hospital stay, and increased early mortality, but negatively correlated with the cancer-specific survival rate survival rate.
Learning patient-level prediction models across multiple healthcare databases: evaluation of ensembles for increasing model transportability

Published: May 2022

AbstractBackgroundPrognostic models that are accurate could help aid medical decision making. Large observational databases often contain temporal medical data for large and diverse populations of patients. It may be possible to learn prognostic models using the large observational data. Often the performance of a prognostic model undesirably worsens when transported to a different database (or into a clinical setting). In this study we investigate different ensemble approaches that combine prognostic models independently developed using different databases (a simple federated learning approach) to determine whether ensembles that combine models developed across databases can improve model transportability (perform better in new data than single database models)?MethodsFor a given prediction question we independently trained five single database models each using a different observational healthcare database. We then developed and investigated numerous ensemble models (fusion, stacking and mixture of experts) that combined the different database models. Performance of each model was investigated via discrimination and calibration using a leave one dataset out technique, i.e., hold out one database to use for validation and use the remaining four datasets for model development. The internal validation of a model developed using the hold out database was calculated and presented as the ‘internal benchmark’ for comparison.ResultsIn this study the fusion ensembles generally outperformed the single database models when transported to a previously unseen database and the performances were more consistent across unseen databases. Stacking ensembles performed poorly in terms of discrimination when the labels in the unseen database were limited. Calibration was consistently poor when both ensembles and single database models were applied to previously unseen databases.ConclusionA simple federated learning approach that implements ensemble techniques to combine models independently developed across different databases for the same prediction question may improve the discriminative performance in new data (new database or clinical setting) but will need to be recalibrated using the new data. This could help medical decision making by improving prognostic model performance.

Published: May 2022

AbstractThe lockdown imposed in France during the first wave of the COVID-19 pandemic wreaked havoc with access to healthcare. From March 2020 onwards, the oncologists of Foch Hospital, like many others at hospitals throughout the world, were obliged to adapt to the new conditions, including, in particular, the impossibility of seeing patients in classic consultations for the diagnosis and treatment of cancer. Patients with cancer are particularly susceptible to this new virus, due to their immune status, and this made it difficult to carry out standard hospital visits for these patients. Some patients refused to come to the hospital, whereas the doctors decided, for others, that consultation conditions at the hospital were not sufficiently safe, with sanitary measures that had yet to be precisely defined. Telemedicine was one of the adaptations adopted during this period. This mode of consultation was little used before the pandemic, for various reasons, and reimbursement was not automatic. This new approach proved to have limitations as well as advantages, as demonstrated by our empirical ethics research study, a retrospective qualitative survey of the doctors of the oncology and supportive care departments of Foch Hospital, performed during July 2021. The interview grid was based on the studies on telemedicine, oncology, COVID-19 and empirical ethics available at the time. Based on the experience gained in this domain during the first wave of the epidemic, which hit France between March and June 2020, we identified three eligibility criteria for consultations in telemedicine: the consultation concerned should not be the first consultation, the patient should be a known patient that the doctor trusts not to minimize the description of symptoms, and the results of the patient’s evaluations and examinations must be good. It may be appropriate to continue the use of teleconsultation in the future, provided that these criteria are respected.

AbstractA pathogenic strain of Macrococcus caseolyticus (M. caseolyticus) was isolated from wounds infection during an investigation on donkeys in Khartoum State. (122) samples were collected from external wounds (head, abdomen, back and leg) during different seasons. One isolate (124B) was identified using whole-genome sequence analysis. RAST software identified 31 virulent genes of disease and defense, including methicillin-resistant genes, TatR family and ANT(4′)-Ib. Plasmid rep22 was identified by PlasmidFindet-2.0 Server and a CRISPR. MILST-2.0 predicted many novel alleles. NCBI notated the genome as a novel M. caseolyticus strain (DaniaSudan). The MLST−tree−V1 revealed that DaniaSudan and KM0211a strains were interrelated. Strain DaniaSudan was resistant to ciprofloxacin, ceftazidime, erythromycin, oxacillin, clindamycin and kanamycin. Mice modeling showed bacteremia and many clinical signs (swelling, allergy, wounds, and hair loss). Enlargement, hyperemia, adhesions and abscesses were observed in many organs.Constructive conclusionThe prevalence of the strain was 4.73%, with significant differences between collection seasons and locations of wounds. A highly significant association between doses (105 CFU/ml, 102 CFU/ml, Intra-peritoneum and sub-cutaneous) and swelling, developing of allergy and loss of hair (p = 0.001, p = 0.000 and p = 0.005) respectively were seen.This result represents the first report of pathogenic strains of M. caseolyticus worldwide.
The current role of sodium-glucose cotransporter 2 inhibitors in type 2 diabetes mellitus management
Authors: Xu Bo , Li Shaoqian , Kang Bo , Zhou Jiecan 
Published: May 2022

AbstractType 2 diabetes mellitus (T2DM) is a chronic, complex metabolic disease characterized by chronic hyperglycemia causing from insufficient insulin signaling because of insulin resistance or defective insulin secretion, and may induce severe complications and premature death. Sodium-glucose cotransporter-2 (SGLT2) inhibitors are oral drugs used to reduce hyperglycemia in patients with T2DM, including empagliflozin, ertugliflozin, dapagliflozin and canagliflozin. The primary objective of this article is to examine the clinical benefit, safety, and tolerability of the four SGLT2 inhibitors approved by the US FDA. SGLT2 inhibitors increase urinary glucose excretion via inhibiting SGLT2 to decrease renal reabsorption of filtered glucose and reduce the renal threshold for glucose. Rather than stimulating insulin release, SGLT2 inhibitors improve β-cell function by improving glucotoxicity, as well as reduce insulin resistance and increase insulin sensitivity. Early clinical trials have confirmed the beneficial effects of SGLT2 in T2DM with acceptable safety and excellent tolerability. In recent years, SGLT2 inhibitors has been successively approved by the FDA to decrease cardiovascular death and decrease the risk of stroke and cardiac attack in T2DM adults who have been diagnosed with cardiovascular disease, treating heart failure (HF) with reduced ejection fraction and HF with preserved ejection fraction, and treat diabetic kidney disease (DKD), decrease the risk of hospitalization for HF in T2DM and DKD patients. SGLT2 inhibitors are expected to be an effective treatment for T2DM patients with non alcoholic fatty liver disease. SGLT2 inhibitors have a similar safety profile to placebo or other active control groups, with major adverse events such as Ketoacidosis or hypotension and genital or urinary tract infections.

Abstract
Background
In Kyrgyzstan and other Eastern European and Central Asian countries, injection drug use and HIV-related intersectional stigma undermines HIV prevention efforts, fueling a rapidly expanding HIV epidemic. The Kyrgyzstan InterSectional Stigma (KISS) Injection Drug Use Cohort is the first study designed to assess the impact of drug use, methadone maintenance treatment (MMT) and HIV stigma experiences among people who inject drugs (PWID) on HIV prevention service utilization.

Methods
Adult PWID were recruited from Bishkek city and the surrounding rural Chuy Oblast region in northern Kyrgyzstan via modified time location sampling and snowball sampling. All participants completed a baseline rapid HIV test and interviewer-administered survey. A subsample of participants were prospectively followed for three months and surveyed to establish retention rates for future work in the region. Internal reliability of three parallel stigma measures (drug use, MMT, HIV) was evaluated. Descriptive statistics characterize baseline experiences across these three stigma types and HIV prevention service utilization, and assess differences in these experiences by urbanicity.

Results
The KISS cohort (N = 279, 50.5% Bishkek, 49.5% Chuy Oblast) was mostly male (75.3%), ethnically Russian (53.8%), median age was 40 years old (IQR 35–46). Of the 204 eligible participants, 84.9% were surveyed at month 3. At baseline, 23.6% had a seropositive rapid HIV test. HIV prevention service utilization did not differ by urbanicity. Overall, we found 65.9% ever utilized syringe service programs in the past 6 months, 8.2% were utilizing MMT, and 60.8% met HIV testing guidelines. No participants reported PrEP use, but 18.5% had heard of PrEP. On average participants reported moderate levels of drug use (mean [M] = 3.25; α = 0.80), MMT (M = 3.24; α = 0.80), and HIV stigma (M = 2.94; α = 0.80). Anticipated drug use stigma from healthcare workers and internalized drug use stigma were significantly higher among PWID from Bishkek (p < 0.05), while internalized HIV stigma among PWID living with HIV was significantly greater among PWID from Chuy Oblast (p = 0.03).

Conclusion
The KISS cohort documents moderate levels of HIV-related intersectional stigma and suboptimal engagement in HIV prevention services among PWID in Kyrgyzstan. Future work will aim identify priority stigma reduction intervention targets to optimize HIV prevention efforts in the region.
