Abstract
Background
Opportunistic infection is an under-recognized complication of Cushing’s syndrome, with infection due to atypical mycobacterium rarely reported. Mycobacterium szulgai commonly presents as pulmonary infection, with cutaneous infection seldom reported in the literature.

Case Presentation
48-year-old man with a newly-diagnosed Cushing’s syndrome secondary to adrenal adenoma presented with a subcutaneous mass on the dorsum of his right hand, was diagnosed with cutaneous Mycobacterium szulgai infection. The most likely source of the infection was through minor unnoticed trauma and inoculation from a foreign body. The patient’s Cushing’s syndrome, high serum cortisol levels and secondary immune suppression facilitated mycobacterial replication and infection. The patient was successfully treated with adrenalectomy, surgical debridement of cutaneous lesion, and a combination of rifampicin, levofloxacin, clarithromycin, and ethambutol for 6 months. There were no signs of relapse one year after cessation of anti-mycobacterial treatment. A literature review on cutaneous M. szulgai infection to further characterize the clinical characteristics of this condition, identified 17 cases of cutaneous M. szulgai infection in the English literature. Cutaneous M. szulgai infections with subsequent disease dissemination are commonly reported in immunocompromised hosts (10/17, 58.8%), as well as in immunocompetent patients with a history of breached skin integrity, such as invasive medical procedures or trauma. The right upper extremity is the most commonly involved site. Cutaneous M. szulgai infection is well controlled with a combination of anti-mycobacterial therapy and surgical debridement. Disseminated infections required a longer duration of therapy than localized cutaneous infections. Surgical debridement may shorten the duration of antibiotics.

Conclusions
Cutaneous M. szulgai infection is a rare complication of adrenal Cushing’s syndrome. Further studies are needed to provide evidence-based guidelines on the best combination of anti-mycobacterial and surgical therapy for managing this rare infective complication.
Ischaemic stroke with multi-focal venous and arterial thrombosis due to hyperhomocysteinemia: anabolic androgenic steroid use and MTHFR c.667 C > T variant – a case report

AbstractBackgroundSeverely elevated serum homocysteine is a rare cause of ischaemic stroke and extra-cranial arterial and venous thrombosis. Several factors can lead to mild elevation of homocysteine including dietary folate and B12 deficiency, and genetic variants of the methylenetetrahydrofolate reductase (MTHFR) enzyme. The use of Anabolic androgenic steroid (AAS) is under-reported, but increasingly linked to ischaemic stroke and can raise homocysteine levels.Case ReportWe present a case of a man in his 40s with a large left middle cerebral artery (MCA) territory ischaemic stroke and combined multifocal, extracranial venous, and arterial thrombosis. His past medical history was significant for Crohn’s disease and covert use of AAS. A young stroke screen was negative except for a severely elevated total homocysteine concentration, folate and B12 deficiencies. Further tests revealed he was homozygous for the methylenetetrahydrofolate reductase enzyme thermolabile variant (MTHFR c.667 C > T). The etiology of this stroke was a hypercoagulable state induced by raised plasma homocysteine. Raised homocysteine in this case was likely multifactorial and related to chronic AAS use in combination with the homozygousMTHFR c.677 C > Tthermolabile variant, folate deficiency and, vitamin B12 deficiency.ConclusionIn summary, hyperhomocysteinemia is an important potential cause of ischaemic stroke and may result from genetic, dietary, and social factors. Anabolic androgenic steroid use is an important risk factor for clinicians to consider, particularly in cases of young stroke with elevated serum homocysteine. Testing forMFTHRvariants in stroke patients with raised homocysteine may be useful to guide secondary stroke prevention through adequate vitamin supplementation. Further studies looking into primary and secondary stroke prevention in the high-risk MTHFR variant cohort are necessary.

Abstract
Objectives
There is little research examining transnational prenatal care (TPC) (i.e., prenatal care in more than one country) among migrant women. Using data from the Migrant-Friendly Maternity Care (MFMC) - Montreal project, we aimed to: (1) Estimate the prevalence of TPC, including TPC-arrived during pregnancy and TPC-arrived pre-pregnancy, among recently-arrived migrant women from low- and middle-income countries (LMICs) who gave birth in Montreal, Canada; (2) Describe and compare the socio-demographic, migration and health profiles and perceptions of care during pregnancy in Canada between these two groups and migrant women who received no TPC (i.e., only received prenatal care in Canada); and (3) Identify predictors of TPC-arrived pre-pregnancy vs. No-TPC.

Methods
The MFMC study used a cross-sectional design. Data were gathered from recently-arrived (< 8 years) migrant women from LMICs via medical record review and interview-administration of the MFMC questionnaire postpartum during the period of March 2014-January 2015 in three hospitals, and February-June 2015 in one hospital. We conducted a secondary analysis (n = 2595 women); descriptive analyses (objectives 1 & 2) and multivariable logistic regression (objective 3).

Results
Ten percent of women received TPC; 6% arrived during pregnancy and 4% were in Canada pre-pregnancy. The women who received TPC and arrived during pregnancy were disadvantaged compared to women in the other two groups (TPC-arrived pre-pregnancy and No-TPC women), in terms of income level, migration status, French and English language abilities, access barriers to care and healthcare coverage. However, they also had a higher proportion of economic migrants and they were generally healthier compared to No-TPC women. Predictors of TPC-arrived pre-pregnancy included: ‘Not living with the father of the baby’ (AOR = 4.8, 95%CI 2.4, 9.8), ‘having negative perceptions of pregnancy care in Canada (general experiences)’ (AOR = 1.2, 95%CI 1.1, 1.3) and younger maternal age (AOR = 1.1, 95%CI 1.0, 1.1).

Conclusion
Women with more capacity may self-select to migrate during pregnancy which results in TPC; these women, however, are disadvantaged upon arrival, and may need additional care. Already-migrated women may use TPC due to a need for family and social support and/or because they prefer the healthcare in their home country.
Unusual presentation of a case of fetal hepatic mass: a case report

Abstract
Background
Giant hepatic hemangiomas are rare and can cause serious complications that contribute to a high risk of perinatal mortality. The purpose of this article is to review the prenatal imaging features, treatment, pathology, and prognosis of an atypical fetal giant hepatic hemangioma and to discuss the differential diagnosis of fetal hepatic masses.

Case presentation
A gravida 9, para 0 woman at 32 gestational weeks came to our institution for prenatal ultrasound diagnosis. A complex, heterogeneous hepatic mass measuring 5.2 × 4.1 × 3.7 cm was discovered in the fetus using conventional two-dimensional ultrasound. The mass was solid and had both a high peak systolic velocity (PSV) of the feeding artery and intratumoral venous flow. Fetal magnetic resonance imaging (MRI) revealed a clear, hypointense T1-W and hyperintense T2-W solid hepatic mass. Prenatal diagnosis was very difficult due to the overlap of benign and malignant imaging features on prenatal ultrasound and MRI. Even postnatally, neither contrast-enhanced MRI nor contrast-enhanced computed tomography (CT) was useful in accurately diagnosing this hepatic mass. Due to persistently elevated Alpha-fetoprotein (AFP), a laparotomy was performed. Histopathological examination of the mass showed atypical features such as hepatic sinus dilation, hyperemia, and hepatic chordal hyperplasia. The patient was ultimately diagnosed with a giant hemangioma, and the prognosis was satisfactory.

Conclusions
When a hepatic vascular mass is found in a third trimester fetus a hemangioma should be considered as a possible diagnosis. However, prenatal diagnosis of fetal hepatic hemangiomas can be challenging due to atypical histopathological findings. Imaging and histopathological assays can provide useful information for the diagnosis and treatment of fetal hepatic masses.
Anti-scarring effects of conbercept on human Tenon’s fibroblasts: comparisons with bevacizumab

Abstract
Background
Safely inhibiting the formation of scar in the glaucoma filtration surgery (GFS) has always been an issue for clinical glaucoma doctors. Anti-vascular endothelial growth factor (VEGF) agents can reduce angiogenesis, and anti-placental growth factor (PIGF) agents can affect reactive gliosis. However, the effect of conbercept, which can bind to both VEGF and PIGF, on human Tenon’s fibroblasts (HTFs) is unknown.

Methods
HTFs were cultured in vitro and treated with conbercept or bevacizumab (BVZ). No drug was added to the control group. The effects of drugs on cell proliferation were assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, and the collagen type I alpha1(Col1A1) mRNA expression level was measured using quantitative polymerase chain reaction (qPCR). HTF cell migration after drug interventions was evaluated using the scratch wound assay along with the measurement of the expression levels of VEGF and PIGF in human umbilical vein endothelial cells (HUVECs) using enzyme-linked immunosorbent assay, as well as the detection of the VEGF(R) mRNA expression level in HTFs using qPCR.

Results
After the addition of conbercept (0.01, 0.1, and 1 mg/mL) to the cultured HTFs or HUVECs, no significant cytotoxicity was observed compared with the control group, while the cytotoxicity of 2.5 mg/mL BVZ on HTFs was obvious. Conbercept significantly inhibited HTF cell migration and Col1A1 mRNA expression level in HTFs. It was superior to BVZ in inhibiting HTF migration. After the intervention with conbercept, the expression level of PIGF and VEGF in HUVECs significantly decreased; and the inhibitory effect of conbercept on the expression level of VEGF in HUVECs was weaker than that of BVZ. Conbercept was more advantageous than BVZ in inhibiting the expression level of VEGFR-1 mRNA in HTFs. However, its effect in terms of inhibiting the expression level of VEGFR-2 mRNA in HTFs was weaker than that of BVZ.

Conclusion
The results suggested the low cytotoxicity and significant anti-scarring effect of conbercept in HTF with significant anti-PIGF and inferior anti-VEGF effects compared with BVZ, thus providing a better understanding of the role of conbercept in the GFS wound healing process.
A case of choroidal melanocytosis observed by multimodal imaging with laser speckle flowgraphy

Published: April 2023

Abstract
Background
Choroidal melanocytosis is characterized by congenital diffuse melanin pigmentation with extensive parenchymal infiltration of spindle cells in the choroid; however, little is known about the choroidal circulation and morphological changes. We herein report a case of choroidal melanocytosis observed by multimodal imaging with laser speckle flowgraphy (LSFG).

Case Presentation
A 56-year-old woman was referred to our hospital because of serous retinal detachment (SRD) in her left eye. At the initial examination, her best-corrected visual acuity (BCVA) was 1.5 oculus dexter (OD) and 0.8 oculus sinister (OS). An irregular, flat, brownish lesion was noted around the macula OS. Optical coherence tomography showed a choroidal structure with marked hyporeflectivity and SRD where the retinal thickness was preserved. Indocyanine green angiography demonstrated fluorescence blockade throughout. Fundus autofluorescence revealed enlarged macular hypofluorescence, suggesting chronic retinal pigment epithelium damage associated with prolonged SRD. B-mode echography showed no choroidal elevation. Based on the clinical findings, the left eye was diagnosed with choroidal melanocytosis. Four years and 10 months after the initial visit, her BCVA was 0.5 and SRD remained. During the entire period of observation, the mean blur rate (MBR) (mean ± standard deviation) of choroidal blood flow velocity on LSFG was 10.15 ± 0.72 arbitrary units (AU) OD and 1.31 ± 0.06 AU OS.

Conclusion
Choroidal melanocytosis presented with chronic minor circulatory disturbances due to melanocyte proliferation in the choroid, but the markedly low MBR values by LSFG were dissociated from her retinal thickness and visual function. The proliferation of melanocytes may be a cause of overestimating the cold-color signal of LSFG due to their pigmentation.
Declining life expectancy in the Great Lakes region: contributors to Black and white longevity change across educational attainment
Authors: Roberts Max Tyler , Lim Sojung , Reither Eric N. 
Published: April 2023

Abstract
Background
The East North Central Census division (aka the Great Lakes region) experienced a decrease in life expectancy of 0.3 years from 2014 to 2016 – one of the largest declines across the nine Census divisions. Disadvantaged groups that typically have below-average life expectancy, including Black individuals and those without a college education, may have been disproportionately affected by this longevity shift. This investigation examines life expectancy changes among different sex, race, and education groups in the Great Lakes region, and how specific causes of death contributed to within-group longevity changes over time and across age.

Methods
We used 2008 to 2017 death counts from the National Center for Health Statistics and American Community Survey population estimates to measure within-group change in life expectancy at age 25 among non-Hispanic Black and white males and females by educational attainment. We decomposed life expectancy change over time for each subgroup by 24 causes of death and measured their contribution to longevity change across 13 age groups.

Results
Among persons with ≤ 12 years of education, white males and females experienced 1.3- and 1.7-year longevity declines respectively, compared to a 0.6-year decline among Black males and a 0.3-year decline among Black females. Life expectancy declined among all groups with 13–15 years of education, but especially Black females, who experienced a 2.2-year loss. With the exception of Black males, all groups with 16 + years of education experienced longevity gains. Homicide contributed 0.34 years to longevity decline among Black males with ≤ 12 years of education. Drug poisoning made large contributions to longevity losses among Black females with ≤ 12 years of education (0.31 years), white males and females with 13–15 years of education (0.35 and 0.21 years, respectively), and white males and females with ≤ 12 years of education (0.92 and 0.65 years, respectively).

Conclusions
Public health efforts to reduce the risks of homicide among Black males without a college education and drug poisoning among all groups could improve life expectancy and reduce racial and educational longevity disparities in the Great Lakes region.
Awake prone position in COVID-19-related acute respiratory failure: a meta-analysis of randomized controlled trials
Authors: Qin Sun , Chang Wei , Peng Fei , Hu Zihan , Yang Yi 
Published: April 2023

Abstract
Background
We aimed to investigate the effects of awake prone positioning (APP) in nonintubated adult patients with acute hypoxemic respiratory failure due to COVID-19.

Methods
The PubMed, Embase, Web of Science and Cochrane Central Register databases were searched up to June 1, 2022. All randomized trials investigating the effects of APP were included in the present meta-analysis. The primary outcome was intubation rate, and the secondary outcomes included the length of intensive care unit (ICU) stay, hospital stay, and mortality. Prescribed subgroup analysis was also conducted.

Results
A total of 10 randomized trials enrolling 2324 patients were ultimately included in the present study. The results indicated that APP was associated with a significant reduction in the intubation rate (OR 0.77, 95% CI 0.63 to 0.93, P = 0.007). However, no differences could be observed in the length of ICU stay or hospitalization or mortality. Subgroup analysis suggested that patients in the ICU settings (OR 0.74, 95% CI 0.60 to 0.91, P = 0.004), patients whose median APP time was more than 4 h (OR 0.77, 95% CI 0.63 to 0.93, P = 0.008), and patients with an average baseline SpO2 to FiO2 ratio less than 200 (OR 0.75, 95% CI 0.61 to 0.92) were more likely to benefit from APP, indicated a significantly reduced intubation rate.

Conclusion
Based on the current evidence, nonintubated adult patients with hypoxemic respiratory failure due to COVID-19 infection who underwent APP were shown to have a significantly reduced intubation rate. However, no differences in ICU or hospital length of stay or mortality could be observed between APP and usual care.

Giving and receiving thanks: a mixed methods pilot study of a gratitude intervention for palliative patients and their carers
Authors: Bernard Mathieu , Poncin Emmanuelle , Bovet Emilie , Tamches Emmanuel , Cantin Boris , Pralong Josiane , Borasio Gian Domenico 
Published: April 2023

Abstract
Background
Psychological research examining the nature and workings of gratitude has burgeoned over the past two decades. However, few studies have considered gratitude in the palliative care context. Based on an exploratory study which found that gratitude was correlated with better quality of life and less psychological distress in palliative patients, we designed and piloted a gratitude intervention where palliative patients and a carer of their choice wrote and shared a gratitude letter with each other. The aims of this study are to establish the feasibility and acceptability of our gratitude intervention and provide a preliminary assessment of its effects.

Methods
This pilot intervention study adopted a mixed-methods, concurrent nested, pre-post evaluation design. To assess the intervention’s effects, we employed quantitative questionnaires on quality of life, quality of relationship, psychological distress, and subjective burden, as well as semi-structured interviews. To assess feasibility, we considered patients and carers’ eligibility, participation and attrition rates, reasons for refusal to participate, appropriateness of intervention timeframe, modalities of participation, and barriers and facilitators. Acceptability was assessed through post-intervention satisfaction questionnaires.

Results
Thirty-nine participants completed the intervention and twenty-nine participated in interviews. We did not find any statistically significant pre/post intervention changes for patients, but found significant decrease in psychological distress for carers in terms of depression (median = 3 at T0, 1.5 at T1, p = .034) and total score (median = 13 at T0, 7.5 at T1, p = .041). Thematic analysis of interviews indicates that overall, the intervention had: (1) multiple positive outcomes for over a third of interviewees, in the form of positive emotional, cognitive, and relational effects; (2) single positive outcomes for nearly half of interviewees, who experienced emotional or cognitive effects; (3) no effect on two patients; and (4) negative emotional effects on two patients. Feasibility and acceptability indicators suggest that the intervention was well received by participants, and that it should adopt flexible modalities (e.g. writing or dictating a gratitude message) to ensure that it is feasible and adapted to individual needs and preferences.

Conclusions
Larger scale deployment and evaluation of the gratitude intervention, including a control group, is warranted in order to have a more reliable evaluation of its effectiveness in palliative care.

Abstract
Background
Measurement-Based Care (MBC) is an evidence-based practice shown to enhance patient care. Despite being efficacious, MBC is not commonly used in practice. While barriers and facilitators of MBC implementation have been described in the literature, the type of clinicians and populations studied vary widely, even within the same practice setting. The current study aims to improve MBC implementation in adult ambulatory psychiatry by conducting focus group interviews while utilizing a novel virtual brainwriting premortem method.

Methods
Semi-structured focus group interviews were conducted with clinicians (n = 18) and staff (n = 7) to identify their current attitudes, facilitators, and barriers of MBC implementation in their healthcare setting. Virtual video-conferencing software was used to conduct focus groups, and based on transcribed verbatin, emergent barriers/facilitators and four themes were identified. Mixed methods approach was utilized for this study. Specifically, qualitative data was aggregated and re-coded separately by three doctoral-level coders. Quantitative analyses were conducted from a follow-up questionnaire surveying clinician attitudes and satisfaction with MBC.

Results
The clinician and staff focus groups resulted in 291 and 91 unique codes, respectively. While clinicians identified a similar number of barriers (40.9%) and facilitators (44.3%), staff identified more barriers (67%) than facilitators (24.7%) for MBC. Four themes emerged from the analysis; (1) a description of current status/neutral opinion on MBC; (2) positive themes that include benefits of MBC, facilitators, enablers, or reasons on why they conduct MBC in their practice, (3) negative themes that include barriers or issues that hinder them from incorporating MBC into their practice, and (4) requests and suggestions for future MBC implementation. Both participant groups raised more negative themes highlighting critical challenges to MBC implementation than positive themes. The follow-up questionnaire regarding MBC attitudes showed the areas that clinicians emphasized the most and the least in their clinical practice.

Conclusion
The virtual brainwriting premortem focus groups provided critical information on the shortcomings and strengths of MBC in adult ambulatory psychiatry. Our findings underscore implementation challenges in healthcare settings and provide insight for both research and clinical practice in mental health fields. The barriers and facilitators identified in this study can inform future training to increase sustainability and better integrate MBC with positive downstream outcomes in patient care.
