Cholecystectomy and risk of liver disease: a systematic review and meta-analysis of 27 million individuals
Authors: Luo De , Chen Xin-Pei , Dai Yang , Kuang Fei , Kang Mao-Ji , Li Bo , Su Song 
Published: March 2023

Background:
There is still a lack of knowledge on the association between cholecystectomy and liver disease. This study was conducted to summarize the available evidence on the association of cholecystectomy with liver disease and quantify the magnitude of the risk of liver disease after cholecystectomy.

Methods:
PubMed, Embase, Web of Science, and Cochrane Library were searched systematically from database inception to January 2023 to identify eligible studies that evaluated the association between cholecystectomy and the risk of liver disease. Meta-analysis was conducted to obtain a summary odds ratio (OR) and 95% confidence interval (CI) using a random-effects model.

Results:
We identified 20 studies with a total of 27 320 709 individuals and 282 670 liver disease cases. Cholecystectomy was associated with an increased risk of liver disease (OR: 1.63, 95% CI: 1.34–1.98). In particular, cholecystectomy was found to be significantly associated with a 54% increased risk of nonalcoholic fatty liver disease (OR: 1.54, 95% CI: 1.18–2.01), a 173% increased risk of cirrhosis (OR: 2.73, 95% CI: 1.81–4.12), and a 46% increased risk of primary liver cancer (OR: 1.46, 95% CI: 1.18–1.82).

Conclusions:
There is an association between cholecystectomy and the risk of liver disease. Our results suggest that strict surgical indications should be implemented to reduce unnecessary cholecystectomy. Additionally, the routine assessment of liver disease is necessary for patients with a history of cholecystectomy. More prospective large-sample studies are required for better estimates of the risk.

Published: March 2023

Objective:
While platelet rich plasma (PRP) has been extensively studied in treating osteoarthritis (OA), there has been an ongoing debate regarding the efficacy of PRP and the optimal subpopulation for PRP treatment remains unknown. The authors hereby aim to establish a pharmacodynamic model-based meta-analysis to quantitatively evaluate PRP efficacy, comparing with hyaluronic acid (HA) and identify relevant factors that significantly affect the efficacy of PRP treatment for OA.

Methods:
The authors searched for PubMed and the Cochrane Library Central Register of Controlled Trials of PRP randomized controlled trials (RCTs) for the treatment of symptomatic or radiographic OA from the inception dates to 15 July 2022. Participants’ clinical and demographic characteristics and efficacy data, defined as Western Ontario and McMaster Universities Osteoarthritis Index and visual analog scale pain scores at each time point were extracted.

Results:
A total of 45 RCTs (3829 participants) involving 1805 participants injected with PRP were included in the analysis. PRP reached a peak efficacy at ~ 2–3 months after injection in patients with OA. Both conventional meta-analysis and pharmacodynamic maximal effect models showed that PRP was significantly more effective than HA for joint pain and function impairment (additional decrease of 1.1, 0.5, 4.3, and 1.1 scores compared to HA treatment at 12 months for Western Ontario and McMaster Universities Osteoarthritis Index pain, stiffness, function, and visual analog scale pain scores, respectively). Higher baseline symptom scores, older age (≥60 years), higher BMI (≥30), lower Kellgren–Lawrence grade (≤2) and shorter OA duration (<6 months) were significantly associated with greater efficacy of PRP treatment.

Conclusion:
These findings suggest that PRP is a more effective treatment for OA than the more well-known HA treatment. The authors also determined the time when the PRP injection reaches peak efficacy and optimized the targeting subpopulation of OA. Further high-quality RCTs are required to confirm the optimal population of PRP in the treatment of OA.
Chin-tuck assistant system (CAS)—A novel method using auditory feedback for postural maintenance in a chin-tuck maneuver: A randomized trial
Authors: Oh Donghwan , Park Han Sol , Park Myung Won , Kim Ho Jeong , Choi Wan Young , Park Ji-Su 
Published: March 2023

Introduction:
Chin-tuck are effective in patients with dysphagia, where aspiration can occur due to pharyngeal swallowing delays. This study aims to verify whether Chin-tuck Assistant System Maneuver (CAS-M) supplemented with Chin-Tuck Maneuver (CTM) is effective for learning and maintaining correct chin-tuck postures. In addition, we investigated the possibility of using CAS-M as a customized rehabilitation treatment program for patients with poor cognitive ability, attention issues, and general swallowing disorders.

Intervention:
To demonstrate the effectiveness of CAS, we recruited 52 healthy adults and assigned them to 2 groups. The CTM group was trained to maintain the correct chin-tuck posture using the general Chin-Tuck Maneuver, while the CAS-M group was trained using CAS. Four evaluations were conducted using CAS to investigate the degree of postural maintenance of chin-tuck before and after intervention.

Results:
The CAS-M group showed a statistically significant difference in TIME, BEEP, and change (P < .05), but the CTM group showed no statistically significant differences (P < .05). YZ evaluation showed no statistically significant differences in both groups.

Conclusion:
After examining the effects of CAS-M using CAS on healthy adults, we confirmed this to be a more effective method for correct chin-tuck posture than conventional CTM.
The impact of heat waves on the mortality of Chinese population: A systematic review and meta-analysis
Authors: Pan Ranran , Xie Ming , Chen Mengxiang , Zhang Yannan , Ma Jian , Zhou Junhua 
Published: March 2023

Background:
Many studies had shown that with global warming, heat waves may increase the mortality risk of Chinese populations. However, these findings are not consistent. Therefore, we elucidated the associations by meta-analysis and quantified the magnitude of these risks, as well as the underlying factors.

Methods:
We searched the China National Knowledge Infrastructure (CNKI), Wanfang database, PubMed, EMBASE, and Web of Science for literature screening up to Nov 10, 2022, to analyze the effect of heat waves on mortality in the Chinese population. Literature screening and data extraction were performed independently by two researchers and the data were merged by meta-analysis. In addition, we conducted subgroup analysis by sex, age, years of education, region, and number of events to explore the source of heterogeneity.

Results:
Fifteen related studies on the impact on heat waves of the death of Chinese people were included in this study. The results of the meta-analysis showed that heat waves were significantly associated with increased mortality from non-accidental deaths, cardiovascular diseases, stroke, respiratory diseases, and circulatory diseases in the Chinese population: non-accidental mortality (RR = 1.19, 95% CI: 1.13–1.27, P < .01), cardiovascular diseases (RR = 1.25, 95% CI: 1.14–1.38), stroke (RR = 1.11, 95% CI: 1.03–1.20), respiratory diseases (RR = 1.18, 95% CI: 1.09–1.28), and circulatory diseases (RR = 1.11, 95% CI: 1.06–1.17). Subgroup analyses showed that heat waves had a higher risk of non-accidental death for those with <6 years of education than for those with ≥6 years of education. Meta-regression analysis showed that the contribution of the study year to the inter studied heterogeneity was 50.57%. The sensitivity analysis showed that the exclusion of any single study did not materially alter the overall combined effect. The meta-analysis method indicated no obvious evidence of publication bias.

Conclusions:
The results of the review indicated that heat waves were associated with increased mortality in the Chinese population, that attention should be paid to high-risk groups, and that public health policies and strategies should be implemented to more effectively respond to and adapt to climate change.
Acute benzyl alcohol intoxication: An autopsy case report
Authors: Ichimata Shojiro , Hata Yukiko , Zaimoku Ryosuke , Nishida Naoki 
Published: March 2023

Introduction:
The main mechanism of death and the pathological appearance of cases of benzyl alcohol intoxication has not been fully investigated. Autopsy reports of cases of benzyl alcohol intoxication have not been published.

Case presentation:
A 24-year-old man was found in the state of cardiopulmonary arrest at a construction site. He had been performing paint stripping. He was immediately transferred to the hospital, but he did not recover. An autopsy showed focal coloring of the skin without any major caustic injury. A histopathological investigation showed vacuolar degeneration in the epidermis and dermo-epidermal junction, and severe erosion of the tracheal and bronchial mucosa. No pathological changes in the kidney were evident. A neuropathological investigation showed central chromatolysis of neuronal cells in pontine nuclei and grumose degeneration in the cerebellar dentate nucleus. The blood content of benzyl alcohol was 780.0 μg/mL.

Lessons:
Present case suggest that multiple pathways of exposure may be associated with more rapid progression in acute benzyl alcohol intoxication, and that early and/or severe involvement of the central nervous system rather than renal dysfunction may be associated with an early death.
Vaseline gauze packing for the treatment of acute hemorrhagic rectal ulcer: Two case reports
Authors: Yim Sung Kyun , Lee Chang Hun , Kim Seong-Hun , Kim Sang Wook , Seo Seung Young 
Published: March 2023

Rationale:
Acute hemorrhagic rectal ulcer (AHRU) is a relatively rare condition characterized by sudden onset, painlessness, and massive hematochezia in patients with severe underlying conditions. When AHRU is encountered, they can often be successfully controlled endoscopically, though recurrent bleeding is common and an alternative treatment must be sought if initial endoscopic treatment fails. We report 2 cases of AHRU which were successfully treated with Vaseline gauze packing after the failure of endoscopic hemostasis.

Patient concerns:
The first patient was an 88-year-old female that visited our emergency department with hematochezia. She was immobilized because of a left pelvic bone fracture resulting from a slip-down. The initial endoscopy showed fresh blood in her rectum with diffuse ulceration near the dentate line but no active bleeding. However, Massive hematochezia has recurred during conservation. A second patient, an 86-year-old female, debilitated because of schizophrenia, dementia, and past subdural hemorrhage, visited our emergency department, also with massive hematochezia. Her initial endoscopy showed deep ulceration near the dentate line. After admission, she experienced massive hematochezia from an AHRU with an exposed vessel but endoscopic hemostasis failed to control bleeding.

Diagnoses:
Both patients were diagnosed as AHRU based on the endoscopic findings.

Interventions:
In both cases, Vaseline gauze packing was performed for bleeding control.

Outcomes:
After Vaseline gauze packing, no further bleeding occurred and follow-up endoscopy showed definitive improvement of ulcers.

Lessons:
Based on these cases, we suggest that Vaseline gauze packing may be the alternative treatment for the AHRU which is located near the dentate line when endoscopic hemostasis is difficult or failed. Although further research is needed, Vaseline gauze packing has several potential advantages for the treatment of AHRU, especially in cases involving critically ill elderly patients.
A case report: An unusual presentation of adenoid cystic carcinoma of the lacrimal gland
Authors: Liang Meiqin , Yu Zhirui , Wang Feng 
Published: March 2023

Rationale:
Adenoid cystic carcinoma (ACC) is the most common malignant epithelial tumor of the lacrimal gland with the highest malignant degree. ACC of the lacrimal gland is characterized by symptoms of <1 years duration. We present a 38-year-old male patient who complained of an enlarging mass in the left lacrimal fossa for almost 10 years previous to the diagnosis of ACC.

Patient concerns:
A 38-year-old male patient visited our ophthalmology clinic with a chief complaint of a mass in his left upper lid, which had enlarged significantly over the previous months.

Diagnoses:
Magnetic resonance imaging with intravenous Gadobutrol showed moderate and homogenous mass enhancement. Bone destruction is found. The periosteum is not eroded. The magnetic resonance imaging finding was supportive for malignancy. Histopathological examination of the specimen revealed solid tumor showing a cribriform pattern mixed small amount of basaloid cell proliferation. Therefore, the final diagnose was Adenoid cystic carcinoma of the lacrimal gland.

Interventions:
The treatment included en bloc resection of the mass and adjacent bone and radiotherapy.

Outcomes:
In 1 year follow-up after operation, there is no recurrence. Visual acuity is 30/30. The left eye shows limitation on abduction.

Lessons:
The present case demonstrates an unusual progression of ACC of the Lacrimal Gland.
A fetus of partial urorectal septum malformation sequence characterized by complete septate uterus: A case report
Authors: Zhai Jingfang , Cao Shenghan , Wang Xuezhen , Liu Ying , Zhang Bei 
Published: March 2023

Rationale:
Urorectal septum malformation sequence (URSMS) is an extremely uncommon anomaly characterized by imperforate anus accompanied by multiple genitourinary malformations. Here, we report a case of URSMS identified by the autopsy and classified into partial URSMS. Prenatal diagnosis is challenging for clinicians due to the difficulty of early identification of URSMS and the relative lack of specific features in ultrasound. We intend to share our experiences.

Patient concerns:
One fetus was indicated abdominal cystic structure, abdominal effusion and right renal pelvis separation (7 mm) by ultrasound at 28 + 1 week’s gestation. After the pregnancy was terminated, the fetal tissues were performed to be tested by autopsy, copy number variation sequencing and whole exon sequencing.

Diagnoses:
Based on the clinical characteristics, ultrasound, autopsy, and genetic test findings, the fetus was diagnosed with URSMS.

Interventions:
After genetic counseling, the couple opted to terminate her pregnancy.

Outcomes:
The copy number variation results of the fetus showed a 0.48-MB duplication fragment of uncertain significance on chromosome 8p23.3, while the whole-exome sequencing revealed a SAL-LIKE 1 gene mutation. The autopsy of the fetus showed imperforate anusa, the abdominal cyst was further confirmed with complete septate uterus and the lower urethra and vagina converge formed a lumen.

Lessons:
Individuals with URSMS during the fetal period might be misdiagnosed due to atypical features of URSMS. Once structural abnormalities especially cystic mass of the futuses in the lower abdomen, URSMS should be considered.
Implementation of an Assault Prevention Quality Improvement Initiative in an Urban Emergency Department
Authors: Mallett-Smith Sheila , Jadalla Ahlam , Hardan-Khalil Kholoud , Sarff Laura , Brady Margaret 
Published: March 2023

Background:
Emergency department (ED) health care workers experience high rates of workplace violence (WPV).

Local Problem:
Patient-to-staff physical assaults at an urban, academic adult ED ranged between 1 and 5 per month, with a rate of 0.265 per 1000 patient visits.

Methods:
A quality improvement initiative, guided by the Social Ecological Model framework that contextualized WPV in the ED setting, informed the development of a Risk for Violence Screening Tool (RVST) to screen adult patients presenting to the ED.

Interventions:
Plan-Do-Study-Act cycles were utilized to implement a violence prevention bundle that incorporated the RVST, an alert system, and focused assault reduction strategies.

Results:
Patient-to-staff physical assaults decreased to a rate of 0.146 per 1000 patient visits.

Conclusions:
Risk for violence screening, an alert system, and assault prevention strategies provide opportunities for nurse leaders to promote ED workplace safety.
Special anatomy series: understanding fascicular anatomy of the brachial plexus: reverse mouse in maze game
Authors: Chiou-Tan Faye Y. 
Published: March 2023

Background:
The objective of this paper is to teach the physician fascicular anatomy of the brachial plexus.

Method:
To achieve this, we will reach back to historical references that researched brachial plexus fascicular anatomy.

Results:
An applied anatomy system was created by which the lesion in the brachial plexus can rapidly be localized. This system is called the “reverse mouse in maze” game, which is a teaching tool created at this institution for resident physicians. Color coding helps localize the lesion rapidly. Black indicates where the lesion is not. Overlap of other colors points to where the lesion likely is. Finally, if the colors do not overlap, there could be 2 lesions. Example hypothetical cases are reviewed as part of this manuscript. Fascicular anatomy can be dizzying to learn and difficult to memorize for the novice physician. To localize the lesion rapidly in the clinical setting and for real-time oral board exams, we found this technique to be useful.

Conclusion:
Awareness that fascicular anatomy of the brachial plexus exists helps localize and explain needle findings on electromyography that may be confusing. The “reverse mouse in maze” localization strategy helps rapidly localize the lesion(s) and also hopefully prevents unnecessary needle testing sampling during the electromyography test.
Investigating burnout of Rehabilitation Medicine trainees: an Australian cross-sectional study
Authors: Ponsford Michael W. , Bilszta Justin L. , McKenzie Dean , Fedele Bianca , Olver John 
Published: March 2023

Background:
In Rehabilitation Medicine, there is an increased incidence of burnout compared with other specialties, with burnout affecting over 50% of rehabilitation physicians. There remains limited research investigating burnout in Rehabilitation Medicine trainees.

Aim:
To investigate the frequency of burnout, and associations between burnout and workplace and demographic factors, among Australian registered Rehabilitation Medicine trainees.

Methods
This cross-sectional study administered the Mini-Z Burnout Survey via the Qualtrics survey platform. The presence of burnout was determined on responses to Survey Item 3. Binary logistic regression evaluated associations between burnout presence and workplace and demographic (age, sex, and stage of training) variables. An open-ended question addressing workplace stresses underwent qualitative content analysis.

Results:
Of the potential 220 registered trainees, 18.2% (39) consented to participate. Burnout was reported by 54.6% (18/33) of respondents with complete data. Logistic regression analyses revealed 2 Mini-Z items were significantly associated with burnout; job stress (odds ratio=22.9; 95% CI=3.5–145.8, P<0.001) and a hectic/chaotic work atmosphere (odds ratio=5.0; 95% CI=1.01–24, P=0.045). There was no significant association between burnout and the remaining Mini-Z items or between burnout and the demographic variables. Content analysis of responses to the open-ended question identified 3 themes: training issues; work place demands; personal health/work-life balance concerns.

Conclusion:
This Australian-first study identified significant burnout in a cohort of Rehabilitation Medicine trainees. The sources of stress identified can be used to modify workplace environments and education requirements and promote well-being among trainees.
Case Volume and Readiness to Deploy: Clinical Opportunities for Active-Duty Surgeons Outside of Military Hospitals
Authors: Sheldon MAJ Rowan R , Bozzay MAJ Joseph D , Brown LTC Shaun R 
Published: March 2023

Background:
The Military Health System (MHS) utilizes a readiness program that identifies the knowledge, skills, and abilities (KSAs) necessary for surgeons to provide combat casualty care. Operative productivity is assigned an objective score based upon case type and complexity and totaled to assess overall readiness. As of 2019, only 10.1% of surgeons met goal readiness threshold. At one tertiary Military Treatment Facility (MTF), leadership has taken an aggressive approach towards increasing readiness by forming Military Training Agreements (MTAs) and allowing Off Duty Employment (ODE). We sought to quantify the efficacy of this approach.

Study Design
Operative logs from 2021 were obtained from surgeons assigned to the MTF. Cases were assigned CPT codes and processed through the KSA calculator (Deloitte; London, UK). Each surgeon was then surveyed to identify time away from clinical duties for deployment or military training.

Results:
Nine surgeons were present in 2021 and spent an average of 10.1 weeks (19.5%) abroad. Surgeons performed 2348 cases (Avg 261 ± 95) including 1575 (Avg 175; 67.1%) at the MTF, 606 (Avg 67.3; 25.8%) at MTAs, and 167 (Avg 18.6, 7.1%) during ODE. Adding MTA and ODE caseloads increased KSA scores by 56% (17,765 ± 7,889 v 11,391 ± 8,355). Using the MHS threshold of 14,000, three of nine (33.3%) surgeons met the readiness threshold from MTF productivity alone. Including all cases, seven of nine (77.8%) surgeons met threshold.

Conclusions:
Increased utilization of MTAs and ODE significantly augment average caseloads. These cases provide considerable benefit and result in surgeon readiness far exceeding the MHS average. Military leadership can maximize the chances of meeting readiness goals by encouraging clinical opportunities outside the MTF.
B. trematum Bacteraemia Secondary to an Empyema in an Immunocompromised Host: A Case Report and Review of the Literature.
Authors: Wong Crystal S L , Calungsud Lynna Grace , La My-Van 
Published: March 2023

Introduction:
Bordetella trematum infection remains uncommon. More cases of bacteraemia are reported in recent years with the primary infection largely originating from skin and soft tissue sites. Yet, our understanding of its virulence, antibiotic susceptibility profile and treatment is still limited.
Case presentation:
We report the first case of B. trematum bacteraemia from a left-sided empyema. An 87-year old lady with a past medical history of ischemic heart disease, diabetes mellitus complicated by nephropathy and locally advanced left breast adenocarcinoma presented with fever, productive cough and shortness of breath. The B. trematum isolates from blood and pleural fluid were identified by MALDI-TOF and 16S rRNA sequencing. Ceftriaxone and azithromycin commenced empirically on admission were switched to piperacillin-tazobactam after 2 days due to lack of clinical improvement. Despite a pleurocentesis and one week of piperacillin-tazobactam with microbiological clearance in blood, she continued to deteriorate. Decision to withdraw treatment was made in view of her prognosis, and she succumbed on the 14th day of admission. The isolate was susceptible to piperacillin-tazobactam, imipenem and meropenem but had reduced susceptibility or was non-susceptible to cefuroxime, cefotaxime, ceftazidime, cefepime, the aminoglycosides and fluoroquinolones.
Conclusion:
Invasive B. trematum infection is associated with significant mortality. Consensus for antibiotic treatment remains unclear, with limited susceptibility data to support specific antibiotic use. We expect more clinical cases will surface with improved microbial identification systems, as well as enhanced clinical awareness. Standardised and more robust susceptibility work are needed to provide clear recommendations and establish consensus in treating invasive infections.
