Moderating role of functioning level on the association between suicidal ideation and delayed-onset post-traumatic stress disorder.

OBJECTIVES: This study aimed to investigate the relationship between suicidal ideation at baseline and the development of post-traumatic stress disorder (PTSD) in individuals who have experienced physical injuries, with a specific focus on how this relationship is moderated by the patient's functioning level. METHODS: Participants were consecutively recruited from a trauma center and prospectively followed for two years. At baseline, suicidal ideation was assessed using the Brief Psychiatric Rating Scale, and functioning level was evaluated using the Social and Occupational Functioning Assessment Scale. During the follow-up, PTSD diagnosis was established using the Clinician-Administered PTSD Scale for DSM-5. Binary and multinomial logistic regression analyses were employed to examine the associations between suicidal ideation, functioning level, and PTSD. RESULTS: Of the 1014 participants analyzed, 114 (11.2%) developed PTSD, with early-onset observed in 79 (7.8%) and delayed-onset in 35 (3.5%) cases. Suicidal ideation at baseline was significantly associated with both early- and delayed-onset PTSD. Notably, higher functioning individuals with baseline suicidal ideation had an increased likelihood of developing delayed-onset PTSD, while this association was not significant in lower functioning individuals, with significant interaction terms. Additionally, suicidal ideation was a consistent predictor of early-onset PTSD across all functioning levels. CONCLUSION: The impact of baseline suicidal ideation on PTSD varies depending on the individual's functioning level, with higher functioning individuals being more vulnerable to delayed-onset PTSD. These findings underscore the importance of considering functional status in the assessment and intervention of PTSD following physical trauma.

Impact of suicidality on delayed-onset post-traumatic stress disorder is modified by age: A two-year longitudinal study.

OBJECTIVES: This study aimed to investigate the relationship between early suicidality and post-traumatic stress disorder (PTSD) onset in patients with physical injuries, focusing on age as a modifying factor. METHODS: At baseline, 1014 patients were evaluated for suicidality, age divided into younger (<60 years) vs. older (≥60 years) groups, and potential covariates. PTSD was diagnosed at follow-up at 3, 6, 12, and 24 months, and then were categorized into early-onset (within the first six months after trauma) and delayed-onset (more than six months after trauma). Logistic regression models were used after adjusting for covariates. RESULTS: Presence of suicidality at baseline was significantly associated with delayed-onset PTSD in older but not younger patients with significant interaction terms, whereas it was significantly associated with early-onset PTSD across all age groups. CONCLUSION: Age-specific associations were found between suicidality and PTSD onset. The findings highlight the importance of early suicidality assessment, especially in older patients for ongoing monitoring and support, and underscore the critical need for early PTSD identification and intervention for all ages.

Clinical relevance of vaginal natural orifice transluminal endoscopic surgery (vNOTES) in gynecology.

This study reviews the progress and recent advances in vaginal natural orifice transluminal endoscopic surgery (vNOTES) as a minimally invasive gynecologic procedure. The proposed advantages of vaginal natural orifice transluminal surgery include enhanced cosmesis due to a scarless procedure, better exposure compared with the pure vaginal approach, tolerable pain scores, fewer perioperative complications, and a shorter hospital stay. Recent advances in surgical instrumentation and technology have improved the feasibility of vNOTES as an innovative treatment option for gynecological conditions. However, technical challenges and training issues must be overcome before its widespread use. As a promising surgical innovation, further randomized comparative studies are required to clarify the safety and effectiveness of vNOTES in gynecology.

Frequency of peripheral PD-1+regulatory T cells is associated with treatment responses to PARP inhibitor maintenance in patients with epithelial ovarian cancer.

BACKGROUND: Poly (adenosine diphosphate [ADP]-ribose) polymerase inhibitors (PARPis) are becoming the standard of care for epithelial ovarian cancer (EOC). Recently, clinical trials of triple maintenance therapy (PARPi+anti-angiogenic agent+anti-PD-1/L1) are actively ongoing. Here, we investigated the immunological effects of PARPi or triple maintenance therapy on T cells and their impact on clinical responses. METHODS: We collected serial blood from EOC patients receiving PARPi therapy (cohort 1: PARPi, n = 49; cohort 2: olaparib+bevacizumab+pembrolizumab, n = 31). Peripheral T cells were analyzed using flow cytometry and compared according to the PARPi response. Progression-free survival (PFS) was assessed according to prognostic biomarkers identified in a comparative analysis. RESULTS: Regulatory T cells (Tregs) were suppressed by PARPi therapy, whereas PD-1 was not significantly changed. Short PFS group exhibited a higher percentage of baseline PD-1+Tregs than long PFS group, and the patients with high percentage of PD-1+Tregs before treatment showed poor PFS in cohort 1. However, the expression of PD-1 on Tregs significantly decreased after receiving triple maintenance therapy, and the reduction in PD-1+Tregs was associated with superior PFS in cohort 2 (P = 0.0078). CONCLUSION: PARPi suppresses Tregs, but does not affect PD-1 expression. Adding anti-PD-1 to PARPi decreases PD-1+Tregs, which have negative prognostic value for PARPi monotherapy.

Ghrelin Modifies the Impact of Life Stress on Suicidality in Patients With Acute Coronary Syndrome.

OBJECTIVE: This study investigated associations of life stressors and serum ghrelin levels with suicidal ideation (SI), and evaluated the potential mediating effect of ghrelin on associations between life stressors and SI in patients with acute coronary syndrome (ACS). METHODS: In total, 969 ACS patients recruited from a tertiary university hospital in Korea within 2 weeks of disease onset were evaluated in terms of life stressors (using the List of Threatening Events Questionnaire), serum ghrelin levels, and SI (using the "suicidal thoughts" item of the Montgomery-Asberg Depression Rating Scale). Covariates included sociodemographics, depression, vascular risk factors, and disease severity. After 1 year, 711 patients were re-evaluated in terms of SI; logistic regression was performed with adjustment for covariates. RESULTS: Life stressors were significantly associated with SI at baseline and follow-up. Serum ghrelin showed no such associations, but high levels thereof mediated associations of life stressors with SI; significant interaction terms were also observed after adjustment for covariates. CONCLUSION: By evaluating life stressors and serum ghrelin levels, clinical prediction of SI in the acute and chronic phases of ACS could be improved.

Possible Link between Serotonin and Interleukin 18 on Suicidality in Patients with Acute Coronary Syndrome.

Objective: We investigated effects of serum serotonin and interleukin 18 levels on suicidal ideation (SI) at acute and chronic phases of acute coronary syndrome (ACS). Methods: Recent-onset 969 ACS patients were evaluated for serum serotonin and interleukin 18 levels; and SI by the "suicidal thoughts" item of the Montgomery-Åsberg Depression Rating Scale. After 1-year, 711 patients were re-evaluated for SI. Logistic regression models were used adjustment for potential covariates. Results: Associations between serum interleukin 18 and SI at both phases were significant only in the lower serotonin group. Conclusion: By evaluating serum serotonin and interleukin 18 levels, the clinical prediction of SI of ACS may be improved.

Associations of systemic inflammation and social support with suicidal ideation in patients with acute coronary syndrome and stroke.

BACKGROUND: This study aimed to investigate associations of serum high-sensitivity C-reactive protein (hsCRP) and social support (SS) levels with suicidal ideation (SI), and to evaluate potential modifying effects of SS on the associations between serum hsCRP levels and SI in two longitudinal cohorts with cardio-/cerebrovascular diseases. METHODS: 1152 acute coronary syndrome (ACS) and 423 stroke patients were recruited at baseline within 2 weeks of disease onset, and evaluated for: i) serum hsCRP levels; ii) SS by the Social Support Scale and Social Undermining Scale; iii) SI by the "suicidal thoughts" item of the Montgomery-Åsberg Depression Rating Scale; and iv) covariates including socio-demographics, depression, vascular risk factors, and index disease severity. At 12-month follow-up, SI was re-evaluated. Logistic regression models were used to adjust for potential covariates. RESULTS: In the ACS cohort, higher serum hsCRP and lower SS levels were significantly associated with SI at baseline; and only lower SS levels were significantly associated with SI at follow-up. In the stroke cohort, lower SS levels were significantly associated with SI at baseline; but no other association was found. Associations of serum hsCRP levels with SI at both baseline and follow-up were only significant at higher SS levels with significant interaction terms in both cohorts. LIMITATIONS: This study evaluated SI, but not suicide attempts or death; it also used a single-center design. CONCLUSIONS: By considering SS evaluations with routine serum hsCRP levels in cardio-/cerebrovascular disease, clinical prediction of SI both at acute and chronic phases of the diseases might be improved.

Differential effects of anxiety on long-term outcomes of acute coronary syndrome and stroke according to their disease severities.

This study investigated associations of anxiety at the acute phase with long-term outcomes of acute coronary syndrome (ACS) and stroke, and potential modifying effects of cardiovascular/cerebrovascular severity at onset. In 1152 ACS and 423 stroke patients with recent onset, long-term follow-up for cardio-cerebro-vascular outcomes was conducted. Acute-phase anxiety predicted long-term outcomes, but these associations were significant only in patients with great initial disease severities with significant interaction terms in both diseases after adjustment for relevant covariates. Clinical prediction of cardio-cerebro-vascular prognosis might be improved by screening for anxiety and disease severities in the acute phase of ACS and stroke.

Modifying Effect of the Interleukin-18 Level on the Association between BDNF Methylation and Long-Term Cardiovascular Outcomes in Patients with Acute Coronary Syndrome.

This study investigated the potential modifying effects of the level of the serum interleukin-18 (IL-18) on the association between BDNF methylation status and long-term cardiovascular outcomes in patients with acute coronary syndrome (ACS). Hospitalized ACS patients were recruited sequentially from 2006 to 2012. At baseline, the IL-18 level and BDNF methylation status were evaluated in 969 patients who were followed for major adverse cardiac events (MACEs) for 5-12 years, until 2017 or death. The time to first composite or individual MACE was compared between individuals with lower and higher average BDNF methylation levels (in the low- and high-IL-18 groups, respectively) using a Cox proportional hazards model. After adjusting for potential covariates, the modifying effects of IL-18 and average BDNF methylation levels on the initial composite and individual MACEs were examined. In the high-IL-18 group, but not in the low-IL-18 group, a higher average BDNF methylation level was associated with increases in composite MACEs (HR (95% CI) = 2.15 (1.42-3.26)), all-cause mortality (HR (95% CI) = 1.89 (1.11-3.22)), myocardial infarction (HR (95% CI) = 1.98 (1.07-3.67)), and percutaneous coronary intervention (HR (95% CI) = 1.81 (1.01-3.23)), independent of confounding variables. The interaction effect between the IL-18 and average BDNF methylation levels on composite MACEs (p = 0.019) and myocardial infarction (p = 0.027) was significant after adjusting for covariates. Analysis of BDNF methylation status and IL-18 levels may help identify ACS patients who are most likely to have adverse clinical outcomes.

Serotonin modifies the impact of sleep disturbance on suicidality in patients with acute coronary syndrome.

Background: This study investigated the associations of sleep disturbance and serum serotonin levels with suicidal ideation, and evaluated the potential modifying effects of serotonin on these associations in patients with the acute coronary syndrome (ACS). Methods: In total, 969 ACS patients were recruited from a tertiary university hospital in Korea within 2 weeks of disease onset and evaluated in terms of sleep disturbance (using the Leeds Sleep Evaluation Questionnaire), serum serotonin levels, and suicidal ideation (using the "suicidal thoughts" item of the Montgomery-Åsberg Depression Rating Scale). Covariates included sociodemographics, depression, vascular risk factors, and disease severity. After 1 year, 711 patients were re-evaluated in terms of suicidal ideation. Logistic regression analysis was performed with adjustment for covariates. Results: Sleep disturbance was significantly associated with suicidal ideation at baseline and follow-up. Serum serotonin showed no such association but modified the association of sleep disturbance with suicidal ideation such that it was significant only in the lower serum serotonin group, with significant interaction terms obtained after adjustment for relevant covariates. Conclusion: Evaluating sleep disturbance and serum serotonin levels could improve the accuracy of clinical predictions of suicidal ideation in the acute and chronic phases of ACS.

Impact of the establishment of a trauma center on blunt traumatic spleen injury treatment: Comparison between pre-traumatic center and trauma center periods.

BACKGROUND: The spleen is a commonly injured intra-abdominal organ from blunt trauma. In cases of traumatic blunt spleen injury, immediate treatment is often required. This study aimed to investigate the prognostic impact of the establishment of a trauma center on the treatment of patients with blunt trauma injury to the spleen. METHODS: We retrospectively reviewed 235 patients who visited our center from 2012 to 2019 for blunt trauma injury to the spleen. The study period was divided into two groups: January 2012 to September 2015 was the pre-center period (PCP), and September 2015 to December 2019 was the trauma center period (TCP). In each period, there were three treatment groups: Surgical group, embolization group, and conservative treatment group. The primary outcome was mortality, and the secondary outcomes were patient characteristics, such as injury severity score and abbreviated injury scale score, time from admission to intervention (both surgery and angiography embolization), and rate of spleen-preserving surgery. RESULTS: In the conservative treatment group, the Hb and hct values were relatively low in the TCP than in the PCP (p=0.007, p=0.008, respectively). The intensive care unit admission rate was relatively high in the TCP (72.9% vs. 90.6%, p=0.031). The ISS was relatively low in the TCP (18 vs. 17, p=0.001). In the surgical group, the time taken to transfer patients to the operating room after admission was greatly reduced in the TCP (151 min vs. 107 min, p=0.028). In the embolization group, the patient's age and SBP were lower in the PCP than in the TCP (p=0.003, p=0.049, respectively); three patients had undergone embolization with CPR in the PCP, and no patient underwent CPR in the TCP. There were three deaths in PCP and none in the TCP (p=0.05). CONCLUSION: The establishment of a trauma center has led to improvements in the treatment quality and prognosis of patients with blunt trauma injury to the spleen receiving either of the three treatments.

Supranormal arterial oxygen tension only during the first six hours after cardiac arrest is associated with unfavourable outcomes.

BACKGROUND: Multiple studies have investigated the association between hyperoxaemia following cardiac arrest (CA) and unfavourable outcomes; however, they have yielded inconsistent results. Most previous studies quantified oxygen exposure without considering its timing or duration. We investigated the relationship between unfavourable outcomes and supranormal arterial oxygen tension (PaO2 ), commonly defined as PaO2 > 100 mmHg, at specific time intervals within 24 h following CA. METHODS: This retrospective observational study included 838 adult non-traumatic patients with CA. The first 24 h following CA were divided into four 6-h time intervals, and the first 6-h period was further divided into three 2-h segments. Multivariable logistic regression analyses were conducted to assess associations of the highest PaO2 and time-weighted average PaO2 (TWA-PaO2 ) values at each time interval with unfavourable outcomes at hospital discharge (cerebral performance categories 3-5). RESULTS: The highest PaO2 (p = .028) and TWA-PaO2 (p = .022) values during the 0-6-h time interval were significantly associated with unfavourable outcomes, whereas those at time intervals beyond 6 h were not. The association was the strongest at supranormal PaO2 values within the 0-2-h time interval, becoming significant at PaO2 values ≥ 150 mmHg. During the first 6 h, longer time spent at ≥150 mmHg of PaO2 was associated with an increased risk of unfavourable outcomes (p = .038). The results were consistent across several sensitivity analyses. CONCLUSION: Supranormal PaO2 during but not after the first 6 h following cardiac arrest was independently associated with unfavourable outcomes.

Antiphospholipid syndrome with renal and splenic infarction after blunt trauma: A case report.

BACKGROUND: In trauma patients, bleeding is an immediate major concern. At the same time, there are few cases of acute vascular occlusion after blunt trauma, and it is unclear what assessment and diagnosis should be considered for these cases. Herein, we describe a patient diagnosed with antiphospholipid syndrome after a hypercoagulable workup for acute renal and splenic vascular occlusion due to blunt trauma. CASE SUMMARY: A 20-year-old man was admitted to the emergency department with abdominal pain after hitting a tree while riding a sled 10 h ago. He had no medical history. Radiological investigations revealed occlusion of the left renal artery with global infarction of the left kidney and occlusion of branches of the splenic artery with infarction of the central portion of the spleen. Attempted revascularization of the left renal artery occlusion through percutaneous transluminal angioplasty failed due to difficulty in passing the wire through the total occlusion. Considering the presence of acute multivascular occlusions in a young man with low cardiovascular risk, additional laboratory tests were performed to evaluate hypercoagulability. The results suggested a high possibility of antiphospholipid syndrome. Treatment with a subcutaneous injection of enoxaparin was started and changed to oral warfarin after two weeks. The diagnosis was confirmed, and he continued to visit the rheumatology outpatient clinic while taking warfarin. CONCLUSION: A hypercoagulable workup can be considered in trauma patients with acute multivascular occlusion, especially in young patients with low cardiovascular risk.

Dexamethasone, a Synthetic Glucocorticoid, Induces the Activity of Androgen Receptor in Human Dermal Papilla Cells.

Psychosocial stress stimulates the secretion of glucocorticoids (GCs), which are stress-related neurohormones. GCs are secreted from hair follicles and promote hair follicle regression by inducing cellular apoptosis. Moreover, the androgen receptor (AR) is abundant in the balding scalp, and androgens suppress hair growth by binding to AR in androgenetic alopecia. First, by using immunofluorescence, we investigated whether the treatment of dermal papilla (DP) cells with dexamethasone (DEX), a synthetic GC, causes the translocation of the glucocorticoid receptor (GR) into the nucleus. DEX treatment causes the translocation of the GR into the nucleus. Next, we investigated whether stress-induced GCs affect the AR, a key factor in male pattern baldness. In this study, we first assessed that DEX increases the expression of AR mRNA in non-balding DP cells, which rarely express AR without androgen. RU486, a GR antagonist, attenuated DEX-inducible AR mRNA expression and AR activation in human non-balding DP cells. In addition, AR translocated into the nucleus after DEX treatment. Furthermore, we indeed showed that the expression of AR was induced in the nucleus by DEX in DP cells of human and mouse hair follicles. Our results first suggest that stress-associated hair loss may be due to increased AR expression and activity induced by DEX. These results demonstrate that hair loss occurs in non-balding scalps with low AR expression.

Incidence of postoperative thrombotic events in ovarian cancer patients with a de-escalated prophylactic strategy: A retrospective cohort study.

OBJECTIVE: This study aimed to determine the incidence of thrombotic events in ovarian cancer patients following a de-escalated prophylactic strategy and to stratify risk groups. METHODS: We reviewed the records of patients who underwent debulking surgery for ovarian cancer at a single institution between January 2007 and May 2019. We identified clinically diagnosed and radiologically confirmed cases of thrombotic events-classified as pulmonary thromboembolism (PE), deep vein thrombosis (DVT), and other thrombotic events-within 6 months of debulking surgery. RESULTS: After excluding 13 patients diagnosed with thromboembolism at the baseline or during neoadjuvant chemotherapy, 799 were analyzed. Since the introduction of medical prophylaxis at our institution in 2009, 482 patients (60%) received medical prophylaxis with subcutaneous injection of low molecular weight heparin for 5 days with mechanical prophylaxis, whereas 317 (40%) received mechanical prophylaxis only. After debulking surgery, thrombotic events occurred in 28 patients (3.5%) including PE (n = 11), DVT (n = 10), and other thrombotic events (n = 7). Multivariable analysis identified age, body mass index (BMI), and operative duration as independent risk factors associated with thrombotic events. A thrombotic event was an independent prognostic factor for overall survival (HR 2.17, 95% CI 1.16-4.1). A cut-off analysis for pre-operative identifiable risk factors showed age < 57 years and BMI < 21 could help define low-risk groups. One patient from 172 low-risk patients (0.58%) experienced a thrombotic event. CONCLUSIONS: The thrombotic event incidence was low in our cohort. A de-escalated prophylaxis strategy may be considered in young (age < 57 years) and lean (BMI < 21) patients.

Restoration of Immune Privilege in Human Dermal Papillae Controlling Epithelial-Mesenchymal Interactions in Hair Formation.

BACKGROUND: Hair follicles are among a handful of organs that exhibit immune privilege. Dysfunction of the hair follicle immune system underlies the development of inflammatory diseases, such as alopecia areata. METHODS: Quantitative reverse transcription PCR and immunostaining was used to confirm the expression of major histocompatibility complex class I in human dermal papilla cells. Through transcriptomic analyses of human keratinocyte stem cells, major histocompatibility complex class I was identified as differentially expressed genes. Organ culture and patch assay were performed to assess the ability of WNT3a conditioned media to rescue immune privilege. Lastly, CD8+ T cells were detected near the hair bulb in alopecia areata patients through immunohistochemistry. RESULTS: Inflammatory factors such as tumor necrosis factor alpha and interferon gamma were verified to induce the expression of major histocompatibility complex class I proteins in dermal papilla cells. Additionally, loss of immune privilege of hair follicles was rescued following treatment with conditioned media from outer root sheath cells. Transcriptomic analyses found 58 up-regulated genes and 183 down-regulated genes related in MHC class I+ cells. Using newborn hair patch assay, we demonstrated that WNT3a conditioned media with epidermal growth factor can restore hair growth. In alopecia areata patients, CD8+ T cells were increased during the transition from mid-anagen to late catagen. CONCLUSION: Identification of mechanisms governing epithelial and mesenchymal interactions of the hair follicle facilitates an improved understanding of the regulation of hair follicle immune privilege.

Modifying effect of the serum level of brain-derived neurotrophic factor (BDNF) on the association between BDNF methylation and long-term cardiovascular outcomes in patients with acute coronary syndrome.

Introduction: This study investigated the potential modifying effects of the serum brain-derived neurotrophic factor (sBDNF) level on the association between BDNF methylation status and long-term cardiovascular outcomes in acute coronary syndrome (ACS) patients. Methods: From 2006 to 2012, hospitalized ACS patients were consecutively recruited. The sBDNF level and BDNF methylation status were assessed at baseline in 969 patients who were followed up for major adverse cardiac events (MACEs) over 5-12 years, until 2017 or death. Cox proportional hazards models were utilized to compare the time to first composite or individual MACEs between individuals with lower and those with higher average BDNF methylation levels in the low and high sBDNF groups, respectively. The modifying effects of the sBDNF and average BDNF methylation levels on first composite and individual MACEs were analyzed using Cox proportional hazards models after adjusting for potential covariates. Results: In the low sBDNF group, a higher average BDNF methylation level was linked to an increase in composite MACEs independent of confounding variables, but not in the high sBDNF group [HR (95 percent CI) = 1.04 (0.76-1.44)]. The interaction effect between the sBDNF and average BDNF methylation levels on composite MACEs was significant after adjusting for covariates (P = 0.008). Conclusion: Combining the BDNF methylation status and sBDNF levels may help identify ACS patients who are likely to have unfavorable clinical outcomes.

Genetic Differences between Physical Injury Patients With and Without Post-traumatic Syndrome: Focus on Secondary Findings and Potential Variants Revealed by Whole Exome Sequencing.

Objective: Sudden traumatic physical injuries often cause psychological distress, which may be associated with chronic disability. Although considerable effort has been expended to identify genetic predictors of post-traumatic stress disorder (PTSD) after traumatic events, genetic predictors of psychological distress in response to severe physical injuries have been yet to be elucidated using whole exome sequencing (WES). Here, the genetic architecture of post-traumatic syndrome (PTS), which encompasses a broad range of psychiatric disorders after traumatic events including depression, anxiety disorder, acute stress disorder, and PTSD, was explored using WES in severely physically injured patients, focusing on secondary findings and potential PTS-related variants. Methods: In total, 141 severely physically injured patients were consecutively recruited, and PTS was evaluated within 1 month of the injury. Secondary findings were analyzed according to PTS status. To identify PTS-related variants, genome-wide association analyses and the optimal sequencing kernel association test were performed. Results: Of the 141 patients, 88 (62%) experienced PTS. There were 108 disease-causing variants in severely physically injured patients. As secondary findings, the stress- and inflammation-related signaling pathways were enriched in the PTS patients, while the glucose metabolism pathway was enriched in those without PTS. However, no significant PTS-related variants were identified. Conclusion: Our findings suggest that genetic alterations in stress and inflammatory pathways might increase the likelihood of PTS immediately after severe physical injury. Future studies with larger samples and longitudinal designs are needed.

Stent Graft Placement in the Top-Down Direction for Treating Traumatic Intra-Abdominal Suprahepatic Inferior Vena Cava Rupture: A Case Report.

PURPOSE: The treatment of suprahepatic inferior vena cava (IVC) ruptures results in high mortality rates due to difficulty in performing the surgical procedure. Here, we present a case of successful endovascular management of a life-threatening suprahepatic IVC rupture with top-down placement of a stent graft. CASE REPORT: A 33-year-old woman was involved in a traffic accident and presented to our emergency department due to unstable hemodynamics after blunt abdominal wall trauma. Computed tomography (CT) revealed massive extravasation of contrast agent from the suprahepatic IVC, which suggested traumatic suprahepatic IVC rupture. To seal the IVC, to salvage major hepatic veins, and to prevent migration of the stent graft into the right side of the heart after placement, an aortic cuff with a proximal hook was introduced in a top-down direction via the right internal jugular vein. After closure of the injured IVC, the patient's hemodynamics improved, and additional laparotomy was performed. After 3 months of trauma care, the patient recovered and was discharged. Follow-up CT after 58 months showed a patent stent graft within the IVC. CONCLUSION: Endovascular management with top-down placement of a stent graft is a viable option for emergent damage control in patients with life-threatening hemorrhage from IVC rupture.

Risk of developing major depressive disorder in polycystic ovary syndrome: a retrospective cohort study.

This study aimed to investigate the risk of developing major depressive disorder (MDD) in women with polycystic ovary syndrome (PCOS). As a population-based retrospective cohort study based on the Korean National Health Insurance Claims Database and National Health Information Database, newly diagnosed 26,251 women with PCOS with age matched 131,480 women without PCOS from 2007 to 2010 were followed longitudinally and the subsequent occurrence of newly onset MDD was evaluated. The risk of developing MDD in women with PCOS after adjusting for various confounding variables was higher compared to women without PCOS (hazard ratio [HR]1.34, 95% confidence intervals [CI] 1.29-1.40, p<.0001). Stratified by the body mass index, the risk of being admitted to the hospital due to MDD was the highest in the overweight PCOS (HR 2.53, 95% CI 1.71-3.76, p<.0001). The risk of developing MDD was higher in women with PCOS compared to women without PCOS. Maintenance of the appropriate body weight should be emphasised as the hazard ratio of developing MDD was higher in overweight women with PCOS.Impact statementWhat is already known on this subject? PCOS is a multisystem disorder associated with various comorbidities including diabetes mellitus, infertility and endometrial cancer.What do the results of this study add? Women with PCOS showed a higher risk of developing MDD compared to age matched women without PCOS in this multivariate analysis after adjusting for body-mass-index, smoking habit, socio-economic status, residential area, blood glucose, and blood cholesterol. The risk of being admitted to hospital due to MDD was the highest in PCOS with BMI ≥ 25.What are the implications of these findings for clinical practice and/or further research? PCOS should not be considered as a condition confined to ovulatory dysfunction and dermatologic problems, but the higher risk of developing MDD should be recognised. The importance of maintaining an appropriate BMI should be emphasised, as the risk of being admitted to the hospital due to MDD increased in overweight and obese women with PCOS.
