Abstract
Background
Pneumocystis jirovecii pneumonia (PCP) with acute respiratory failure can result in development of pneumothorax during treatment. This study aimed to identify the incidence and related factors of pneumothorax in patients with PCP and acute respiratory failure and to analyze their prognosis.

Methods
We retrospectively reviewed the occurrence of pneumothorax, including clinical characteristics and results of other examinations, in 119 non-human immunodeficiency virus patients with PCP and respiratory failure requiring mechanical ventilator treatment in a medical intensive care unit (ICU) at a tertiary-care center between July 2016 and April 2019.

Results
During follow up duration, twenty-two patients (18.5%) developed pneumothorax during ventilator treatment, with 45 (37.8%) eventually requiring a tracheostomy due to weaning failure. Cytomegalovirus co-infection (odds ratio 13.9; p = 0.013) was related with occurrence of pneumothorax in multivariate analysis. And development of pneumothorax was not associated with need for tracheostomy and mortality. Furthermore, analysis of survivor after 28 days in ICU, patients without pneumothorax were significantly more successful in weaning from mechanical ventilator than the patients with pneumothorax (44% vs. 13.3%, p = 0.037). PCP patients without pneumothorax showed successful home discharges compared to those who without pneumothorax (p = 0.010).

Conclusions
The development of pneumothorax increased in PCP patient with cytomegalovirus co-infection, pneumothorax might have difficulty in and prolonged weaning from mechanical ventilators, which clinicians should be aware of when planning treatment for such patients.

Abstract
Background
The management of non-small cell lung cancer (NSCLC) has become increasingly complex due to the evolution of personalized medicine approaches. Such approaches are characterized by the necessity of adequate tumor samples; hence, improved biopsy techniques are needed. Transbronchial lung cryobiopsy is a novel endoscopic procedure designed to collect peripheral pulmonary tissue, and it is currently employed in interstitial lung diseases. The use of this technique in oncology might result in improved mediastinum staging and molecular characterizations; however, available data involving the use of a cryoprobe on mediastinal lymph nodes are still limited.

Case presentation
Here we present a series of five consecutive patients who underwent endoscopic assessment of mediastinal lymph nodes for oncologic reasons. All patients were subjected both to endobronchial ultrasound-guided transbronchial needle aspiration (EBUS TBNA) and cryobiopsy of mediastinal lymph nodes during the same procedure, and no complications were observed. In three of the reported cases, both cryobiopsy and cell block from EBUS TBNA were positive, while in one case cryobiopsy was not diagnostic and EBUS TBNA was negative; moreover, one case showed discordance between the procedures, as cryobiopsy was negative and cell block obtained from multiple stations was diagnostic for small cell lung cancer. In one case involving a patient treated for lymphoma, cryobiopsy provided more complete histologic characterization, and in another case involving a patient affected by NSCLC cryobiopsy provided more material for molecular analyses.

Conclusion
This case presentation series suggests that cryobiopsy, which has been generally used on peripheral lung lesions so far, is a feasible and safe approach for diagnosis and staging of mediastinal lymph nodal involvement, especially when station 7 is involved. Compared to EBUS TBNA, cryobiopsy might provide more adequate histological samples, with a possible impact on molecular characterizations and, therefore, therapeutic decisions. However, the learning curve of the procedure has not to be understated and optimal protocols for implementing this technique are needed. In our opinion, further studies designed to integrate the routine use of cryobiopsy in current practice for solid and eventually hematologic tumors with mediastinal lymph node involvement are warranted.
Respiratory-related death in individuals with incident asthma and COPD: a competing risk analysis
Authors: Gayle Alicia V. , Minelli Cosetta , Quint Jennifer K. 
Published: January 2022

Abstract
Background
Distinguishing between mortality attributed to respiratory causes and other causes among people with asthma, COPD, and asthma-COPD overlap (ACO) is important. This study used electronic health records in England to estimate excess risk of death from respiratory-related causes after accounting for other causes of death.

Methods
We used linked Clinical Practice Research Datalink (CPRD) primary care and Office for National Statistics mortality data to identify adults with asthma and COPD from 2005 to 2015. Causes of death were ascertained using death certificates. Hazard ratios (HR) and excess risk of death were estimated using Fine-Gray competing risk models and adjusting for age, sex, smoking status, body mass index and socioeconomic status.

Results
65,021 people with asthma and 45,649 with COPD in the CPRD dataset were frequency matched 5:1 with people without the disease on age, sex and general practice. Only 14 in 100,000 people with asthma are predicted to experience a respiratory-related death up to 10 years post-diagnosis, whereas in COPD this is 98 in 100,000. Asthma is associated with an 0.01% excess incidence of respiratory related mortality whereas COPD is associated with an 0.07% excess. Among people with asthma-COPD overlap (N = 22,145) we observed an increased risk of respiratory-related death compared to those with asthma alone (HR = 1.30; 95% CI 1.21–1.40) but not COPD alone (HR = 0.89; 95% CI 0.83–0.94).

Conclusions
Asthma and COPD are associated with an increased risk of respiratory-related death after accounting for other causes; however, diagnosis of COPD carries a much higher probability. ACO is associated with a lower risk compared to COPD alone but higher risk compared to asthma alone.

Published: January 2022

Abstract
Background
Primary Ewing sarcoma (ES)/peripheral primitive neuroectodermal tumors (pPNETs) are aggressive bone tumors that rarely occur in the axial skeleton, including the cranial bone and mobile spine. The purpose of this study was to investigate whether there were any differences in patient characteristics, treatment strategies, and outcomes between patients with ES/pPNETs of the cranial bone and those with ES/pPNETs of the mobile spine.

Methods
A retrospective study was performed on 33 patients with ES/pPNETs who had been surgically treated and pathologically confirmed at our institution between 2010 and 2020. Patient characteristics were compared using Fisher exact tests or independent t tests. Survival rates were estimated via Kaplan–Meier survival analysis and compared using log-rank tests.

Results
Thirteen patients had ES/pPNETs of the cranial bone (39.4%), while 20 patients had ES/pPNETs of the mobile spine (60.6%). Patients with ES/pPNETs of the cranial bone had a younger mean age (14.8 vs 22.6 years; p = 0.047) and longer mean disease duration (2.5 vs 1.9 months; p = 0.008) compared with those of patients with ES/pPNETs of the mobile spine. Kaplan–Meier analysis showed that gross total resection (GTR) and radiotherapy resulted in a longer median survival time. The overall survival rates and progression-free survival rates of patients with ES/pPNETs of the cranial bone versus those of the mobile spine were not significantly different (p = 0.386 and p = 0.368, respectively).

Conclusions
Patients with ES/pPNETs of the cranial bone were younger compared to patients with ES/pPNETs of the mobile spine. There was no significant difference in the prognosis of patients with ES/pPNETs of the cranial bone versus those of the mobile spine. Taken together, our findings suggest that GTR and radiotherapy offer the best prognosis for improved long-term survival.

Published: January 2022

Abstract
Background
Ingestion of fish bones leading to gastric perforation and inducing abscess formation in the caudate lobe of the liver is very rare.

Case presentation
A 67-year-old man presented to our hospital with a 2-day history of subxiphoid pain. There were no specific symptoms other than pain. Laboratory tests showed only an increase in the number and percentage of neutrophils. Contrast-enhanced Computerized tomography (CT) of the abdomen showed two linear dense opacities in the gastric cardia, one of which penetrated the stomach and was adjacent to the caudate lobe of the liver, with inflammatory changes in the caudate lobe. We finally diagnosed his condition as a caudate lobe abscess secondary to intestinal perforation caused by a fishbone based on the history and imaging findings. The patient underwent 3D laparoscopic partial caudate lobectomy, incision and drainage of the liver abscess, and fishbone removal. The procedure was successful and we removed the fishbone from the liver. The patient was discharged on the 9th postoperative day without other complications.

Conclusions
Liver abscess caused by foreign bodies requires multidisciplinary treatment. Especially when located in the caudate lobe, we must detect and remove the cause of the abscess as early as possible. Foreign bodies that perforate the gastrointestinal tract can penetrate to the liver and cause abscess formation, as in this case. When exploring the etiology of liver abscesses, we should investigate the general condition, including the whole gastrointestinal tract.

Published: January 2022

Abstract
Background
We have improved and named a new reverse rolling-mat type lymph node dissection, which effectively solves the dilemma faced by the traditional lymph node dissection in hand-assisted laparoscopic D2 radical gastrectomy through the optimization of the surgical procedure. However, the relevant clinical data are still scarce. The study aims to compare the clinical effects of two surgical procedure and explore the safety and feasibility of “reverse procedure”.

Study design
The clinicopathological data of 195 patients who underwent hand-assisted D2 radical total gastrectomy (HALTG) in our hospital from January 2011 to September 2017 were collected. A retrospective case–control study was used to compare the clinical outcomes of the two patterns of lymph node dissection. Among them, 89 patients underwent “cabbage type” lymph node dissection and 106 patients underwent the “reverse procedure” lymph node dissection.

Results
There were no significant differences between the two groups of patients in terms of gender, age, tumor location, incision length, postoperative hospitalization duration, pathological classification, recent complications, long-term recurrence and metastasis. The operation time of “cabbage type” group was shorter than that of “reverse procedure” group (178.35 ± 31.52 min vs 191.25 ± 32.77 min; P = 0.006). While, in the “reverse procedure” group, intraoperative blood loss was less (249.4 ± 143.12 vs 213.58 ± 101.43; P = 0.049), and there were more numbers of lymph nodes dissected (18.04 ± 7.00 vs 32.25 ± 14.23; P < 0.001).

Conclusion
The pattern of reverse rolling-mat type lymph node dissection in HALTG perform well in terms of safety and feasibility.
Trocar-site hernia following laparoscopic salpingo-oophorectomy in a middle-aged Japanese woman: an initial case report after 40 years of experience at a single center and a brief literature review

Published: January 2022

Abstract
Background
In gynecology, the number of laparoscopic surgeries performed has increased annually because laparoscopic surgery presents a greater number of advantages from a cosmetic perspective and allows for a less invasive approach than laparotomy. Trocar site hernia (TSH) is a unique complication that causes severe small bowel obstruction and requires emergency surgery. Its use has mainly been reported with respect to gastrointestinal laparoscopy, such as for cholecystectomy. Contrastingly, there have been few reports on gynecologic laparoscopy because common laparoscopic surgeries, such as laparoscopic salpingo-oophorectomy, are considered low risk due to shorter operative times. In this study, we report on a case of a woman who developed a TSH 5 days postoperatively following a minimally invasive laparoscopic surgery that was completed in 34 min.

Case presentation
A 41-year-old woman who had undergone laparoscopic salpingo-oophorectomy 5 days previously presented with the following features of intestinal obstruction: persistent abdominal pain, vomiting, and inability to pass stool or flatus. A computed tomography scan of her abdomen demonstrated a collapsed small bowel loop that was protruding through the lateral 12-mm port. Emergency surgery confirmed the diagnosis of TSH. The herniated bowel loop was gently replaced onto the pelvic floor and the patient did not require bowel resection. After the surgical procedure, the fascial defect at the lateral port site was closed using 2-0 Vicryl sutures. On the tenth postoperative day, the patient was discharged with no symptom recurrence.

Conclusions
The TSH initially presented following laparoscopic salpingo-oophorectomy; however, the patient did not have common risk factors such as obesity, older age, wound infection, diabetes, and prolonged operative time. There was a possibility that the TSH was caused by excessive manipulation during the tissue removal through the lateral 12-mm port. Thereafter, the peritoneum around the lateral 12-mm port was closed to prevent the hernia, although a consensus around the approach to closure of the port site fascia had not yet been reached. This case demonstrated that significant attention should be paid to the possibility of patients developing TSH. This will ensure the prevention of severe problems through early detection and treatment.

Abstract
Background
The mental health of refugee women is often affected by multiple risk factors in their social ecology. Assessing these risk factors is foundational in determining potential areas for intervention. We used the social ecological model to examine risk factors associated with self-reported mental health symptoms among clinic-attending Syrian refugee women in Jordan. We hypothesize that individual (older age, unmarried, have more children under 18, difficulty reading/writing with ease), interpersonal (intimate partner violence [IPV]), community and societal level risk factors (greater number of postmigration stressors), will be associated with depression, anxiety, and post-traumatic stress disorder (PTSD) symptoms.

Methods
We surveyed 507 women using a cross-sectional clinic-based systematic sampling approach between April and November 2018. We used multivariable regressions to examine associations between different risk factors in the social ecology on depression, anxiety, and PTSD. Additional multivariable regressions explored associations between specific postmigration stressors and mental health conditions.

Results
We found rates of depression among our sample to be 62.92%; anxiety 57.46%; and PTSD 66.21%. Our hypothesis was partially supported. At the individual level, age was directly associated with anxiety (aOR 1.04, 95% CI [1.02, 1.06]) and PTSD (aOR 1.03, 95% CI [1.01, 1.06]), while marriage decreased odds for depression (aOR 0.41, 95% CI [0.19, 0.92]) and PTSD (aOR 0.36, 95% CI [0.15, 0.87]). IPV was associated with depression (aOR 2.78, 95% CI [1.72, 4.47]); anxiety (aOR 3.30, 95% CI [2.06, 5.27]); and PTSD (aOR 5.49, 95% CI [3.09, 9.76]). Each additional community and societal risk factor (postmigration stressor) increased the odds for depression (aOR 1.32, 95% CI [1.22, 1.42]), anxiety (aOR 1.28, 95% CI [1.19, 1.39]), and PTSD (aOR 1.46, 95% CI [1.33, 1.60]).

Conclusion
Understanding social ecological risk factors associated with mental health conditions of Syrian refugee women is vital to addressing their mental health needs. IPV and postmigration stressors are consistently impactful with all mental health conditions. IPV resulted in the largest odds increase for all mental health conditions. Multilevel interventions are needed to address mental health risk factors at multiple levels of the social ecology.

Abstract
Background
The COVID-19 pandemic has brought unprecedented changes to medical education. However, no data are available regarding the impact the pandemic may have on medical training in Mexico. The aim of our study was to evaluate and identify the medical school students’ perceptions of the changes in their clinical training due to the pandemic in Mexico.

Methods
This was a cross-sectional study where a previous validated online survey was translated and adapted by medical education experts and applied to senior medical students from March to April of 2021. The 16-item questionnaire was distributed online combining dichotomous, multiple-choice, and 5-point Likert response scale questions. Descriptive and multivariate analyses were performed to compare the student’s perceptions between public and private schools.

Results
A total of 671 responses were included in the study period. Most participants were from public schools (81%) and female (61%). Almost every respondent (94%) indicated it was necessary to obtain COVID-19 education, yet only half (54%) received such training. Students in private schools were less likely to have their clinical instruction canceled (53% vs. 77%, p = 0.001) and more likely to have access to virtual instruction (46% vs. 22%, p = 0.001) when compared to students from public schools. Four out of every five students considered their training inferior to that of previous generations, and most students (82%) would consider repeating their final year of clinical training.

Conclusions
The impact of the COVID-19 on medical education in Mexico has been significant. Most final-year medical students have been affected by the cancellation of their in-person clinical instruction, for which the majority would consider repeating their final year of training. Efforts to counterbalance this lack of clinical experience with virtual or simulation instruction are needed.

Published: January 2022

Abstract
Background and Aim
Nurses perception and attitude towards an older patient can positively or negatively influence the quality rendered. As students under training, the views of this population needs to be sought and shaped to improve the quality of care the older patients receive. This is because life expectancy is on the rise. The study aimed to explore students’ perception of ageing and their attitude towards care of the older adults.

Methods and materials
An exploratory descriptive design was used. Data form containing the sociodemographic attributes of the students and a semi-structured interview form developed by the researchers in line with the literature. The participants interviewed were student nurses who had been in clinical practice for at least one semester. Four focus group discussions (FGD) were held.

Results
Average age of the participants was 22.30 years. An equal number of males and females (15 each) were recruited to have a balance in gender. Students expressed that they saw the older adults as their grandparents so they try to accord them respect and care. However, older adults are perceived not receptive to nurses in training. The students stated that registered nurses neglected the basic care of older adults such as diaper changes, bathing, and feeding, and would rather beckon student nurses to attend to the older adults.

Conclusion
Gerontology as a stand-alone course is necessary for early years of training to give an in-depth education to nursing students and instil a positive attitude towards older adult patients.
