Abstract
Background
Clinical uncertainty is inherent for people with frailty and multimorbidity. Depleted physiological reserves increase vulnerability to a decline in health and adverse outcomes from a stressor event. Evidence-based tools can improve care processes and outcomes, but little is known about priorities to deliver care for older people with frailty and multimorbidity. This study aimed to explore the preferences and priorities for patients, family carers and healthcare practitioners to enhance care processes of comprehensive assessment, communication and continuity of care in managing clinical uncertainty using evidence-based tools.

Methods
A parallel mixed method observational study in four inpatient intermediate care units (community hospitals) for patients in transition between hospital and home. We used a discrete choice experiment (DCE) to examine patient and family preferences and priorities on the attributes of enhanced services; and stakeholder consultations with practitioners to discuss and generate recommendations on using tools to augment care processes. Data analysis used logit modelling in the DCE, and framework analysis for consultation data.

Results
Thirty-three patients participated in the DCE (mean age 84 years, SD 7.76). Patients preferred a service where family were contacted on admission and discharge (β 0.36, 95% CI 0.10 to 0.61), care received closer to home (β − 0.04, 95% CI − 0.06 to − 0.02) and the GP is fully informed about care (β 0.29, 95% CI 0.05–0.52).
Four stakeholder consultations (n = 48 participants) generated 20 recommendations centred around three main themes: tailoring care processes to manage multiple care needs for an ageing population with frailty and multimorbidity; the importance of ongoing communication with patient and family; and clear and concise evidence-based tools to enhance communication between clinical teams and continuity of care on discharge.

Conclusion
Family engagement is vital to manage clinical uncertainty. Both patients and practitioners prioritise engaging the family to support person-centred care and continuity of care within and across care settings. Patients wished to maximise family involvement by enabling their support with a preference for care close to home. Evidence-based tools used across disciplines and services can provide a shared succinct language to facilitate communication and continuity of care at points of transition in care settings.

Abstract
Background
Muscle pump dysfunction is an essential component of chronic venous disease (CVD) pathology. Aging reduces muscle strength which further weakens the venous return. However, the epidemiology of CVD and its relationship with the physical performance in older persons is poorly studied. We studied the prevalence of CVD in subjects aged over 70 years and its association primarily with the Short Physical Performance Battery (SPPB) and 10 m walk test.

Methods
An accurate clinical leg examination was performed and the Clinical-Etiological-Anatomical-Pathophysiological-classification (CEAP, clinical classification of chronic venous disorders, C1-C6) determined by dermatologists in 552 subjects aged between 70 and 93 years belonging to the Northern Finland Birth Cohort 1966 – Parents’ Study (NFBC-PS). Linear regression analyses were used to examine the association between CVD and functional tests and anthropometric measurements.

Results
The prevalence of CVD (C1-C6) was 54.3%. C1 was diagnosed in 22.1% (n=84), C2 in 15.2% (n=45), C3 in 8.2% (n=45), C4 in 7.8% (43), C5 in 0.4% (n=2) and C6 in 0.5% (n=3). The prevalence and severity of CVD increased with increasing age (p<0.05). Males presented more with severe stages of CVD (C4-C6) (p<0.001). Subjects with CVD had significantly lower total SPPB scores and longer times in the 10 m walk test (p<0.001). The association between CVD severity and SPPB remained statistically significant in females after adjusting for age, body mass index (BMI) and number of children. The 10 m walk test times were associated with CVD when adjusted for sex and age but not after adjusting for BMI.

Conclusions
It is recommended that detailed skin examination of legs should be performed by physicians treating older subjects in order to improve early diagnosis of CVD. We highlight the importance of physical activity in older persons - lower limb activation of older persons with CVD may improve venous return and therefore prevent progression of CVD. We found an association between CVD and gait speed, however, there may exist bidirectional relationship.

Abstract
Background
Multi-drug resistant—tuberculosis (MDR-TB) is an emerging public health concern in Uganda. Prior to 2013, MDR-TB treatment in Uganda was only provided at the national referral hospital and two private-not-for profit clinics. From 2013, it was scaled up to seven regional referral hospitals (RRH). The aim of this study was to measure interim (6 months) treatment outcomes among the first cohort of patients started on MDR-TB treatment at the RRH in Uganda.

Methods
This was a cross-sectional study in which a descriptive analysis of data collected retrospectively on a cohort of 69 patients started on MDR-TB treatment at six of the seven RRH between 1st April 2013 and 30th June 2014 and had been on treatment for at least 9 months was conducted.

Results
Of the 69 patients, 21 (30.4%) were female, 39 (56.5%) HIV-negative, 30 (43.5%) resistant to both isoniazid and rifampicin and 57 (82.6%) category 1 or 2 drug susceptible TB treatment failures. Median age at start of treatment was 35 years (Interquartile range (IQR): 27–45), median time-to-treatment initiation was 27.5 (IQR: 6–89) days and of the 30 HIV-positive patients, 27 (90.0%) were on anti-retroviral treatment with a median CD4 count of 206 cells/microliter of blood (IQR: 113–364.5). Within 6 months of treatment, 59 (85.5%) patients culture converted, of which 45 (65.2%) converted by the second month and the other 14 (20.3%) by the sixth month; one (1.5%) did not culture convert; three (4.4%) died; and six (8.8%) were lost-to-follow up. Fifty (76.8%) patients experienced at least one drug adverse event, while 40 (67.8%) gained weight. Mean weight gained was 4.7 (standard deviation: 3.2) kilograms.

Conclusions
Despite MDR-TB treatment initiation delays, most patients had favourable interim treatment outcomes with majority culture converting early and very few getting lost to follow-up. These encouraging interim outcomes indicate the potential for success of a scale-up of MDR-TB treatment to RRH.

Published: October 2021

Abstract
Background
The worldwide spread of carbapenemase-producing Enterobacteriaceae (CPE) has reduced the clinical utility of carbapenems. Plasmids often play an important role in the spread of genes encoding drug-resistance factors, especially in the horizontal transfer of these genes among species of Enterobacteriaceae. This study describes a patient infected with three species of CPE carrying an identical transferrable IncL/M plasmid.

Methods
Clinical isolates of CPE were collected at St. Luke’s International Hospital, Tokyo, Japan, from 2015 to 2019. Three species of CPE isolates, Enterobacter cloacae, Klebsiella aerogenes and Serratia marcescens, were isolated from a patient who developed severe gallstone pancreatitis associated with bloodstream infection, with all three isolates producing IMP-1 metallo-β-lactamase. The complete sequences of the plasmids of the three isolates were determined by both MiSeq and MinION. The medical chart of this patient was retrospectively reviewed conducted to obtain relevant clinical information.

Results
The three CPE species carried an IncL/M plasmid, pSL264, which was 81,133 bp in size and harbored blaIMP-1. The genetic environment surrounding blaIMP-1 consisted of int1-blaIMP-1-aac(6’)-IIc-qacL-qacEdelta1-sul1-istB-IS21. Conjugation experiments showed that S. marcescens could transmit the plasmid to E. cloacae and K. aerogenes. In contrast, pSL264 could not transfer from E. cloacae or K. aerogenes to S. marcescens.

Conclusion
The IncL/M plasmid pSL264 harboring blaIMP-1 was able to transfer among different species of Enterobacteriaceae in a patient receiving long-term antimicrobial treatment. The worldwide emergence and spread of IncL/M plasmids harboring carbapenemase-encoding genes among species of Enterobacteriaceae is becoming a serious public health hazard.

Abstract
Background
Both fragile X-associated tremor/ataxia syndrome (FXTAS) and late-onset neuronal intranuclear inclusion disease (NIID) show CGG/GGC trinucleotide repeat expansions. Differentiating these diseases are difficult because of the similarity in their clinical and radiological features. It is unclear that skin biopsy can distinguish NIID from FXTAS. We performed a skin biopsy in an FXTAS case with cognitive dysfunction and peripheral neuropathy without tremor, which was initially suspected to be NIID.

Case presentation
The patient underwent neurological assessment and examinations, including laboratory tests, electrophysiologic test, imaging, skin biopsy, and genetic test. A brain MRI showed hyperintensity lesions along the corticomedullary junction on diffusion-weighted imaging (DWI) in addition to middle cerebellar peduncle sign (MCP sign). We suspected NIID from the clinical picture and the radiological findings, and performed a skin biopsy. The skin biopsy specimen showed ubiquitin- and p62-positive intranuclear inclusions, suggesting NIID. However, a genetic analysis for NIID using repeat-primed polymerase chain reaction (RP-PCR) revealed no expansion detected in the Notch 2 N-terminal like C (NOTCH2NLC) gene. We then performed genetic analysis for FXTAS using RP-PCR, which revealed a repeat CGG/GGC expansion in the FMRP translational regulator 1 (FMR1) gene. The number of repeats was 83. We finally diagnosed the patient with FXTAS rather than NIID.

Conclusions
For the differential diagnosis of FXTAS and NIID, a skin biopsy alone is insufficient; instead, genetic analysis, is essential. Further investigations in additional cases based on genetic analysis are needed to elucidate the clinical and pathological differences between FXTAS and NIID.

Abstract
Background
The use of face masks has become ubiquitous in Taiwan during the early COVID-19 pandemic. A name-based rationing system was established to enable the population of Taiwan to purchase face masks. This study is to assess the extent and fairness of face mask supply to the public in Taiwan.

Methods
The weekly face marks supplies were collected from name-based rationing system administrative statistics included national health insurance card and e-Mask selling record. National registered population statistics by age, gender, and district were collected from department of statistics ministry of the interior. The number of COVID-19 non-imported cases of Taiwan was collected from Taiwan centers of disease control.

Results
A total of 146,831,844 person times purchase records from February 6, 2020, to July 19, 2020, the weekly average face mask supply is 0.5 mask (per person) at the start of name-based rationing system, and gradually expanded to the maximum 5.1 masks (per person). Comparing the highest weekly total face mask supply (from Apr 9, 2020, to Apr 15, 2020) in aged 0–9 -, 10–19 -, 20–29 -, 30–39 -, 40–49 -, 50–59 -, 60–69 -,70–79 -, 80–89 -, 90–99, and > 100 years to the register population showed similar distribution between mask supplied people and total population (all standardized difference < 0.1).

Conclusion
The masks supply strategies has gradually escalated the number of face masks for the public, it not only has dominant decreased the barrier of acquiring face mask, but a fair supply for total population use of Taiwan.

Abstract
Background
The role of the subacromial bursa in the development or healing of shoulder pathologies is unclear. Due to this limited knowledge, we aimed to understand specific reactions of the subacromial bursa according to rotator cuff (RC) pathologies compared to non-tendon defects of the shoulder. We hypothesized that the tissue composition and inflammatory status of the bursa are likely to vary between shoulder pathologies depending on the presence and the extent of RC lesion.

Method
Bursa samples from patients with either 1) shoulder instability with intact RC (healthy bursa, control), 2) osteochondral pathology with intact RC, 3) partial supraspinatus (SSP) tendon tear, or 4) full-thickness SSP tear were investigated histologically and on gene expression level.

Result
Bursae from SSP tears differed from non-tendon pathologies by exhibiting increased chondral metaplasia and TGFβ1 expression. MMP1 was not expressed in healthy bursa controls, but strongly increased with full-thickness SSP tears. Additionally, the expression of the inflammatory mediators IL1β, IL6, and COX2 increased with the extent of SSP tear as shown by correlation analysis. In contrast, increased angiogenesis and nerve fibers as well as significantly upregulated IL6 and COX2 expression were features of bursae from patients with osteochondral pathology. Using immunohistochemistry, CD45+ leukocytes were observed in all examined groups, which were identified in particular as CD68+ monocytes/macrophages.

Conclusion
In summary, besides the strong increase in MMP1 expression with SSP tear, molecular changes were minor between the investigated groups. However, expression of pro-inflammatory cytokines correlated with the severity of the SSP tear. Most pronounced tissue alterations occurred for the osteochondral pathology and full-thickness SSP tear group, which demonstrates that the bursal reaction is not exclusively dependent on the occurrence of an SSP tear rather than longstanding degenerative changes. The present bursa characterization contributes to the understanding of specific tissue alterations related to RC tears or non-tendon shoulder pathologies. This pilot study provides the basis for future studies elucidating the role of the subacromial bursa in the development or healing of shoulder pathologies.
Cavernous lymphangioma of the urinary bladder in an adult woman: an additional case report of a rare lesion and literature review
Authors: He Wei , Jin Li , Lin Fang-fang , Qi Xiao-long , He Xiang-lei , Zhang Da-hong , Zhao Ming 
Published: October 2021

Abstract
Background
Urinary bladder lymphangioma is a rare and benign lesion that is often causes symptoms related to irritation and urinary tract obstruction. Because a lymphangioma may resemble a true neoplasm of the urinary bladder clinically, the lesion must be removed for accurate histologic diagnosis and to rule out malignancy.

Case presentation
We present a case of a 40-year-old female who was evaluated for painless gross hematuria. Clinical and diagnostic work up revealed a sharply defined mass involving the wall and bulging into the cavity on the dome of the bladder. Partial cystectomy was performed and histologic findings were compatible with cavernous lymphangioma. The symptom of hematuria relieved after the procedure and the patient was in good status without evidence of recurrence by cystoscopy at follow-up 6 months later.

Conclusions
Lymphangioma of the urinary bladder is treated with surgical excision and seems to have no recurrence once completely resected, but long-time follow-up may be needed.

Published: October 2021

Abstract
Background
Compared with a natural process, surgically induced menopausal women have a higher bone loss rate. This study aims to evaluate early treatment with estradiol valerate on bone turnover markers after surgically induced menopause.

Methods
This prospective study included 41 pre and perimenopausal women who underwent hysterectomy with oophorectomy for benign gynecologic conditions. Two weeks after the operation, all participants were assessed for menopausal hormone therapy (MHT) indications. Estrogen therapy was prescribed for those who had indications and accepted treatment (hormone treatment group). The others who had no MHT indication were allocated to the no-treatment group. Serum CTX and P1NP levels at preoperative and 12 weeks postoperative were measured and set as the primary outcome. Within the same group, serum CTX and P1NP before and after surgical menopause were analyzed using Wilcoxon signed-rank test. ANCOVA was used to compare serum CTX and P1NP at 12 weeks after surgical menopause between the two groups. Spearman's rank correlation coefficient analysis analyzed the correlation between age and baseline bone turnover markers. A p-value of < 0.05 was considered statistically significant.

Results
At 12 weeks after surgery, there were no significant differences in serum CTX and P1NP levels in the hormone treatment group compared to baseline. In contrast, serum CTX and P1NP levels were significantly elevated among women who did not receive hormone treatment (p-value < 0.001 and 0.002, respectively). Serum CTX and P1NP at 12 weeks were significantly different between the two groups (p-value < 0.001 and 0.004, respectively).

Conclusion
Early estrogen administration with oral estradiol valerate could significantly suppress the high bone remodeling in surgically induced menopausal women.

Abstract
Background
Vertigo and dizziness (VD) are among the most frequently seen symptoms in clinics and are important for medical students, especially for those in Chinese standardized residency training (SRT). The aim of our study was to examine the PAL method’s feasibility in the clinical teaching of VD-related diseases for SRT students in China.

Methods
This is a randomized, controlled, multicenter study. A total of 228 residents were invited to participate in this study, of which 198 completed the program. The students were randomized into two groups, and VD-related diseases were taught using lecture-based learning (control group) or peer-assisted learning (PAL). An examination paper and a rating scale were used to evaluate students’ performance in the mastery of VD-related theoretical knowledge and clinical skills, meanwhile students’ perceptions, satisfaction, and risk of burnout were also analyzed using a questionnaire. Independent-samples t-test and chi-square analysis were performed to evaluate statistical significance for continuous variables and categorical variables, respectively, using SPSS 18.0 software.

Results
The PAL group performed better in mastering theoretical knowledge and clinical skills than the control group. And more students believed that PAL could help improve their personal qualities such as teamwork skills. However, more students reported that PAL increased the risk of burnout.

Conclusions
PAL was a suitable and effective method in the clinical teaching of some specialized diseases, especially it was recommended for students who had gained initial knowledge and skills, such as Chinese SRT students. However, we should draw attention to the increased risk of burnout if PAL is intended to be widely used in clinical teaching.

Assessment of the appropriateness of the i-CONSENT guidelines recommendations for improving understanding of the informed consent process in clinical studies
Authors: Fons-Martinez Jaime , Ferrer-Albero Cristina , Diez-Domingo Javier 
Published: October 2021

Abstract
Background
The H2020 i-CONSENT project has developed a set of guidelines that offer ethical recommendations and practical tools aimed at making the informed consent process in clinical studies more comprehensive, tailored, and inclusive. An analysis of the appropriateness of some of its novel recommendations was carried out by a group of experts representing different stakeholders.

Methods
An adaptation of the RAND/UCLA Appropriateness Method was used to assess the level of agreement on the recommendations among 14 representatives of different stakeholders, including patients, regulators, investigators, ethics experts, and the pharmaceutical industry. The process included two rounds of rating and a virtual meeting.

Results
Fifty-three recommendations were evaluated. After the first round, 34 recommendations were judged “appropriate”; 19 were judged “uncertain”; and none was judged “inappropriate”. After the second round, 9 “uncertains” changed to “appropriate”. All recommendations rated medians of 6.5–9 on a 1–9 scale (1 = “extremely inappropriate”, 5 = “uncertain”, 9 = “extremely appropriate”). The sections “General recommendations” and “Gender perspective during the consent process for clinical studies” showed the highest “uncertainty” rating. The four keys to improving the understanding of the ICP in clinical studies are to: (1) consider consent a two-way continuous interaction that begins at the first contact with the potential participant and continues until the end of the study; (2) improve investigators’ communication skills; (3) co-create the information; and (4) use a layered approach, including information to compensate for the potential participant’s possible lack of health literacy and a glossary of terms.

Conclusions
The RAND/UCLA method has demonstrated validity for assessing the appropriateness of recommendations in ethical guidelines. The recommendations of the i-CONSENT guidelines were mostly judged “appropriate” by all stakeholders involved in the informed consent process.
