BACKGROUND
Canada's health care systems underserve people who are transgender and gender diverse (TGD), leading to unique disparities not experienced by other patient groups, such as in accessing gender-affirmation surgery. We sought to explore the experiences of TGD people seeking and accessing gender-affirmation surgery at a publicly funded hospital in Canada to identify opportunities to improve the current system.
METHODS
We used hermeneutic phenomenology according to Max van Manen to conduct this qualitative study. Between January and August 2022, we conducted interviews with TGD people who had undergone penile-inversion vaginoplasty at Women's College Hospital, Toronto, Ontario, since June 2019. We conducted interviews via Microsoft Teams and transcribed them verbatim. We coded the transcripts using NVivo version 12. Using inductive analysis, we constructed themes, which we mapped onto van Manen's framework of lived body, lived time, lived space, and lived human relations.
RESULTS
We interviewed 15 participants who had undergone penile-inversion vaginoplasty; they predominantly self-identified as transgender women ( = 13) and White ( = 14). Participants lived in rural ( = 4), suburban ( = 5), or urban ( = 6) locations. Their median age was 32 (range 27-67) years. We identified 11 themes that demonstrated the interconnected nature of TGD peoples' lived experiences over many years leading up to accessing gender-affirmation surgery. These themes emphasized the role of the body in experiencing the world and shaping identity, the lived experience of the body in shaping human connectedness, and participants' intersecting identities and emotional pain (lived body); participants' experiences of the passage of time and progression of events (lived time); environments inducing existential anxiety or fostering affirmation, the role of technology in shaping participants' understanding of the body, and the effect of liminal spaces (lived space); and finally, the role of communication and language, empathy and compassion, and participants' experiences of loss of trust and connection (lived human relations).
INTERPRETATION
Our findings reveal TGD patients' lived experiences as they navigated a lengthy and often difficult journey to penile-inversion vaginoplasty. They suggest a need for improved access to gender-affirmation surgery by reducing wait times, increasing capacity, and improving care experiences.

BACKGROUND
Transgender and nonbinary (TNB) people experience obstacles that create barriers to accessing health care, including stigmatization and health inequities. Our intention was to describe the lived experiences of TNB patients and identify potential gaps in the education of health care professionals.
METHODS
We conducted a qualitative descriptive study influenced by phenomenology by interviewing with TNB adults who underwent surgery in Canada within the previous 5 years. We recruited participants using purposeful and snowball sampling via online social networking sites. Audio recordings were transcribed. Two authors coded the transcripts and derived the themes.
RESULTS
We interviewed 21 participants, with a median interview duration of 49 minutes. Participants described positive and negative health care encounters that led to stress, confusion, and feelings of vulnerability. Major themes included having to justify their need for health care in the face of structural discrimination; fear and previous traumatic experiences; community as a source of support and information; and the impact of interactions with health care professionals.
INTERPRETATION
Participants detailed barriers to accessing care, struggled to participate in shared decision-making, and desired trauma-informed care principles; they described strength in community and positive interactions with health care professionals, although barriers to accessing gender-affirming care often overshadowed other aspects of the perioperative experience. Additional research, increased education for health care professionals, and policy changes are necessary to improve access to competent care for TNB people.

Previous studies reporting the association between gut microbiota dysbiosis and maternal obesity were mostly confined at the phylum level or at postpartum period. This study aimed to investigate the dynamic changes in gut microbial communities associated with maternal obesity at different time points of pregnancy. We performed 16S rRNA gene V3-V4 amplicon sequencing on stool samples from 110 women in all three trimesters and 1-month postpartum. Maternal gut microbial communities associated with maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) were explored. The influence of maternal obesity on gut microbiota trajectories was determined based on longitudinal shifts in community clusters across the trimesters. The richness index of alpha diversity decreased with the progression of pregnancy, particularly in women with excessive GWG. The evenness index in 2nd trimester was found inversely associated with GWG. Various taxonomic differences in 1st trimester were associated with excessive GWG, whereas limited taxonomic differences in 2nd and 3rd trimesters were associated with pre-pregnancy BMI or GWG. Meanwhile, the gut microbiota trajectory with especially depleted genus Faecalibacterium in 1st trimester was associated with excessive GWG (adjusted odds ratio 5.7, 95% confidence interval 1.2-28.1). Moreover, the longitudinal abundances of genus Lachnospiraceae ND3007 group across gestations were depleted in women with overweight/obese pre-pregnancy BMI, while genus Bifidobacterium enriched in women with excessive GWG. Our study shows that dysbiosis of the gut microbiota in early pregnancy may have a significant impact on excess GWG. The abundance of the genus Faecalibacterium in 1st trimester may be a potential risk factor. Clinical trial number: NCT03785093 (https://classic.clinicaltrials.gov/ct2/show/NCT03785093).

The impact of gestational diabetes mellitus (GDM) on maternal or infant microbiome trajectory remains poorly understood. Utilizing large-scale longitudinal fecal samples from 264 mother-baby dyads, we present the gut microbiome trajectory of the mothers throughout pregnancy and infants during the first year of life. GDM mothers had a distinct microbiome diversity and composition during the gestation period. GDM leaves fingerprints on the infant's gut microbiome, which are confounded by delivery mode. Further, Clostridium species positively correlate with a larger head circumference at month 12 in male offspring but not females. The gut microbiome of GDM mothers with male fetuses displays depleted gut-brain modules, including acetate synthesis I and degradation and glutamate synthesis II. The gut microbiome of female infants of GDM mothers has higher histamine degradation and dopamine degradation. Together, our integrative analysis indicates that GDM affects maternal and infant gut composition, which is associated with sexually dimorphic infant head growth.

INTRODUCTION AND IMPORTANCE
Repairing incisional abdominal wall hernia with nonabsorbable meshes is one of the most common procedures in general surgery. Mesh migration into the intestine is rare but a serious complication. It can occur months or even years after surgery and often presents with vague abdominal pain, making diagnosis tricky.
CASE PRESENTATION
We report a rare case of a 52-year-old female presenting a small bowel obstruction secondary to mesh migration from the abdominal wall into the intestine, 10 years after repeated surgical repair of a ventral incisional hernia. At surgery, a mesh was migrated into a small bowl. The patient had a small bowel resection. The postoperative course was simple and the patient was discharged after 5 days.
CASE DISCUSSION
Incisional hernia repair with mesh is one of the most commonly performed surgical procedures worldwide. Many complications have been linked to the use of mesh; among the most frequently reported are seromas, hematomas, and infections. Mesh migration remains an uncommon event after incisional hernia repair, and even rarer when considering complete migration within the intestinal lumen. The exact cause of this complication remains unknown. Multiple hypotheses have been proposed for mesh migration. Abdominal pain, intermittent or persistent intestinal obstruction, mass formation, and viscus perforation represent the most common clinical manifestation. Total removal of the mesh via laparoscopy or laparotomy is recommended, along with either partial or entire resection of the organ.
CONCLUSION
Mesh migration is a an uncommon possible complication in case of incisional hernia mesh repair and it requires often surgical intervention.

BACKGROUND
ChatGPT is an AI platform whose relevance in the peer review of scientific articles is steadily growing. Nonetheless, it has sparked debates over its potential biases and inaccuracies. This study aims to assess ChatGPT's ability to qualitatively emulate human reviewers in scientific research.
METHODS
We included the first submitted version of the latest twenty original research articles published by the 3rd of July 2023, in a high-profile medical journal. Each article underwent evaluation by a minimum of three human reviewers during the initial review stage. Subsequently, three researchers with medical backgrounds and expertise in manuscript revision, independently and qualitatively assessed the agreement between the peer reviews generated by ChatGPT version GPT-4 and the comments provided by human reviewers for these articles. The level of agreement was categorized into complete, partial, none, or contradictory.
RESULTS
720 human reviewers' comments were assessed. There was a good agreement between the three assessors (Overall kappa >0.6). ChatGPT's comments demonstrated complete agreement in terms of quality and substance with 48 (6.7 %) human reviewers' comments, partially agreed with 92 (12.8 %), identifying issues necessitating further elaboration or recommending supplementary steps to address concerns, had no agreement with a significant 565 (78.5 %), and contradicted 15 (2.1 %). ChatGPT comments on methods had the lowest proportion of complete agreement (13 comments, 3.6 %), while general comments on the manuscript displayed the highest proportion of complete agreement (17 comments, 22.1 %).
CONCLUSION
ChatGPT version GPT-4 has a limited ability to emulate human reviewers within the peer review process of scientific research.

BACKGROUND
Exposure to opioids after surgery is the initial contact for some people who develop chronic opioid use disorder. Hence, effective postoperative pain management, with less reliance on opioids, is critical. The Perioperative Opioid Quality Improvement (POQI) program developed (1) a digital health platform leveraging patient-survey-reported risk factors and (2) a postsurgical pain risk stratification algorithm to personalize perioperative care by integrating several commercially available digital health solutions into a combined platform. Development was reduced in scope by the COVID-19 pandemic.
OBJECTIVE
This pilot study aims to assess the screening performance of the risk algorithm, quantify the use of the POQI platform, and evaluate clinicians' and patients' perceptions of its utility and benefit.
METHODS
A POQI platform prototype was implemented in a quality improvement initiative at a Canadian tertiary care center and evaluated from January to September 2022. After surgical booking, a preliminary risk stratification algorithm was applied to health history questionnaire responses. The estimated risk guided the patient assignment to a care pathway based on low or high risk for persistent pain and opioid use. Demographic, procedural, and medication administration data were extracted retrospectively from the electronic medical record. Postoperative inpatient opioid use of >90 morphine milligram equivalents per day was the outcome used to assess algorithm performance. Data were summarized and compared between the low- and high-risk groups. POQI use was assessed by completed surveys on postoperative days 7, 14, 30, 60, 90, and 120. Semistructured patient and clinician interviews provided qualitative feedback on the platform.
RESULTS
Overall, 276 eligible patients were admitted for colorectal procedures. The risk algorithm stratified 203 (73.6%) as the low-risk group and 73 (26.4%) as the high-risk group. Among the 214 (77.5%) patients with available data, high-risk patients were younger than low-risk patients (age: median 53, IQR 40-65 years, vs median 59, IQR 49-69 years, median difference five years, 95% CI 1-9; P=.02) and were more often female patients (45/73, 62% vs 80/203, 39.4%; odds ratio 2.5, 95% CI 1.4-4.5; P=.002). The risk stratification was reasonably specific (true negative rate=144/200, 72%) but not sensitive (true positive rate=10/31, 32%). Only 39.7% (85/214) patients completed any postoperative quality of recovery questionnaires (only 14, 6.5% patients beyond 60 days after surgery), and 22.9% (49/214) completed a postdischarge medication survey. Interviewed participants welcomed the initiative but noted usability issues and poor platform education.
CONCLUSIONS
An initial POQI platform prototype was deployed operationally; the risk algorithm had reasonable specificity but poor sensitivity. There was a significant loss to follow-up in postdischarge survey completion. Clinicians and patients appreciated the potential impact of preemptively addressing opioid exposure but expressed shortcomings in the platform's design and implementation. Iterative platform redesign with additional features and reevaluation are required before broader implementation.

Review
BACKGROUND Guillain-Barre syndrome (GBS) is a rare immune-mediated peripheral nerve disorder. Among non-infectious factors, surgery has been identified as a potential trigger of the disease. This report presents the case of a 74-year-old man who developed GBS 15 days after a right lower lobectomy for lung adenocarcinoma. CASE REPORT We present a case of a patient who was a former smoker who underwent uniportal video-assisted (U-VATS) right lower lobectomy for localized lung adenocarcinoma. Fifteen days after surgery, he exhibited bilateral lower-limb weakness, widespread paresthesia, and postural instability. Comprehensive diagnostic workup, including clinical assessment, serological tests, cerebrospinal fluid (CSF) analysis, and nerve conduction studies (NCS), confirmed the diagnosis. Notably, CSF analysis revealed albumin-cytological dissociation, with albumin 453.2 mg/L, protein 757 mg/L, glucose 67 mg/dl, 3 white blood cells (WBC)/uL, and polymorphonucleates (PMN) 33%. NCS demonstrated motor and sensory abnormalities. Prompt administration of intravenous immunoglobulins (IVIG) 2 g/kg daily for 5 days resulted in complete recovery within 3 months. CONCLUSIONS This case emphasizes the importance of prompt recognition and management of GBS as a postoperative complication. Neurological examination, neuroimaging, and electrophysiological studies are essential for accurate diagnosis. IVIG therapy remains a cornerstone in GBS management, with favorable outcomes observed in this case. Enhanced awareness among clinicians about the potential association between surgery and GBS is vital to prevent more serious complications and ensure optimal patient management. Further research is crucial to determine the precise pathogenesis and mechanisms of GBS following lung surgery.
