The interacting partner as the immediate environment: Personality, interpersonal dynamics, and bodily synchronization.

OBJECTIVE: In social interactions, humans tend to naturally synchronize their body movements. We investigated interpersonal synchronization in conversations and examined its relationship with personality differences and post-interaction appraisals. METHOD: In a 15-minute semi-structured conversation, 56 previously-unfamiliar dyads introduced themselves, followed by self-disclosing and argumentative conversations. Their bodily movements were video-recorded in a standardized room (112 young adults, aged 18-33, mean = 20.54, SD = 2.74; 58% Dutch, 31% German, 11% other). Interpersonal bodily synchronization was estimated as (a) synchronization strength using Windowed Lagged Cross-Correlations and (b) Dynamic Organization (Determinism/Entropy/Laminarity/Mean Line) using Cross-Recurrence Quantification Analysis. Bodily synchronization was associated with differences in Agreeableness and Extraversion (IPIP-NEO-120) and post-conversational appraisals (affect/closeness/enjoyment) in mixed-effect models. RESULTS: Agreeable participants exhibited higher complexity in bodily synchronization dynamics (higher Entropy) than disagreeable individuals, who also reported more negative affect afterward. Interpersonal synchronization was stronger among extroverts than among introverts and extroverts appraised conversations as more positive and enjoyable. Bodily synchronization strength and dynamic organization were related to the type of conversation (self-disclosing/argumentative). CONCLUSIONS: Interpersonal dynamics were intimately connected to differences in Agreeableness and Extraversion, varied across situations, and these parameters affected how pleasant, close, and enjoyable each conversation felt.

Procedural sedation and analgesia versus general anesthesia for hysteroscopic myomectomy (PROSECCO trial): A multicenter randomized controlled trial.

BACKGROUND: Hysteroscopic resection is the first-choice treatment for symptomatic type 0 and 1 fibroids. Traditionally, this was performed under general anesthesia. Over the last decade, surgical procedures are increasingly being performed in an outpatient setting under procedural sedation and analgesia. However, studies evaluating safety and effectiveness of hysteroscopic myomectomy under procedural sedation are lacking. This study aims to investigate whether hysteroscopic myomectomy under procedural sedation and analgesia with propofol is noninferior to hysteroscopic myomectomy under general anesthesia. METHODS AND FINDINGS: This was a multicenter, randomized controlled noninferiority trial conducted in 14 university and teaching hospitals in the Netherlands between 2016 and 2021. Inclusion criteria were age ≥18 years, maximum number of 3 type 0 or 1 fibroids, maximum fibroid diameter 3.5 cm, American Society of Anesthesiologists class 1 or 2, and having sufficient knowledge of the Dutch or English language. Women with clotting disorders or with severe anemia (Hb < 5.0 mmol/L) were excluded. Women were randomized using block randomization with variable block sizes of 2, 4, and 6, between hysteroscopic myomectomy under procedural sedation and analgesia (PSA) with propofol or under general anesthesia (GA). Primary outcome was the percentage of complete resections, assessed on transvaginal ultrasonography 6 weeks postoperatively by a sonographer blinded for the treatment arm and surgical outcome. Secondary outcomes were the surgeon's judgment of completeness of procedure, menstrual blood loss, uterine fibroid related and general quality of life, pain, recovery, hospitalization, complications, and surgical reinterventions. Follow-up period was 1 year. The risk difference between both treatment arms was estimated, and a Farrington-Manning test was used to determine the p-value for noninferiority (noninferiority margin 7.5% of incomplete resections). Data were analyzed according to the intention-to-treat principle, including a per-protocol analysis for the primary outcome. A total of 209 women participated in the study and underwent hysteroscopic myomectomy with PSA (n = 106) or GA (n = 103). Mean age was 45.1 [SD 6.4] years in the PSA group versus 45.0 [7.7] years in the GA group. For 98/106 women in the PSA group and 89/103 women in the GA group, data were available for analysis of the primary outcome. Hysteroscopic resection was complete in 86/98 women (87.8%) in the PSA group and 79/89 women (88.8%) in the GA group (risk difference -1.01%; 95% confidence interval (CI) -10.36 to 8.34; noninferiority, P = 0.09). No serious anesthesiologic complications occurred, and conversion from PSA to GA was not required. During the follow-up period, 15 serious adverse events occurred (overnight admissions). All were unrelated to the intervention studied. Main limitations were the choice of primary outcome and the fact that our study proved to be underpowered. CONCLUSIONS: Noninferiority of PSA for completeness of resection was not shown, though there were no significant differences in clinical outcomes and quality of life. In this study, hysteroscopic myomectomy for type 0 and 1 fibroids with PSA compared to GA was safe and led to shorter hospitalization. These results can be used for counseling patients by gynecologists and anesthesiologists. Based on these findings, we suggest that hysteroscopic myomectomies can be performed under PSA in an outpatient setting. TRIAL REGISTRATION: The study was registered prospectively in the Dutch Trial Register (NTR 5357; registration date: 11 August 2015; Date of initial participant enrollment: 18 February 2016).

Levonorgestrel-releasing intrauterine system versus endometrial ablation for heavy menstrual bleeding.

BACKGROUND: Heavy menstrual bleeding affects the physical functioning and social well-being of many women. The levonorgestrel-releasing intrauterine system and endometrial ablation are 2 frequently applied treatments in women with heavy menstrual bleeding. OBJECTIVE: This study aimed to compare the effectiveness of the levonorgestrel-releasing intrauterine system with endometrial ablation in women with heavy menstrual bleeding. STUDY DESIGN: This multicenter, randomized controlled, noninferiority trial was performed in 26 hospitals and in a network of general practices in the Netherlands. Women with heavy menstrual bleeding, aged 34 years and older, without a pregnancy wish or intracavitary pathology were randomly allocated to treatment with either the levonorgestrel-releasing intrauterine system (Mirena) or endometrial ablation, performed with a bipolar radiofrequency device (NovaSure). The primary outcome was blood loss at 24 months, measured with a Pictorial Blood Loss Assessment Chart score. Secondary outcomes included reintervention rates, patient satisfaction, quality of life, and sexual function. RESULTS: We registered 645 women as eligible, of whom 270 women provided informed consent. Of these, 132 women were allocated to the levonorgestrel-releasing intrauterine system (baseline Pictorial Blood Loss Assessment Chart score, 616) and 138 women to endometrial ablation (baseline Pictorial Blood Loss Assessment Chart score, 630). At 24 months, mean Pictorial Blood Loss Assessment Chart scores were 64.8 in the levonorgestrel-releasing intrauterine system group and 14.2 in the endometrial ablation group (difference, 50.5 points; 95% confidence interval, 4.3-96.7; noninferiority, P=.87 [25 Pictorial Blood Loss Assessment Chart point margin]). Compared with 14 women (10%) in the endometrial ablation group, 34 women (27%) underwent a surgical reintervention in the levonorgestrel-releasing intrauterine system group (relative risk, 2.64; 95% confidence interval, 1.49-4.68). There was no significant difference in patient satisfaction and quality of life between the groups. CONCLUSION: Both the levonorgestrel-releasing intrauterine system and endometrial ablation strategies lead to a large decrease in menstrual blood loss in women with heavy menstrual bleeding, with comparable quality of life scores after treatment. Nevertheless, there was a significant difference in menstrual blood loss in favor of endometrial ablation, and we could not demonstrate noninferiority of starting with the levonorgestrel-releasing intrauterine system. Women who start with the levonorgestrel-releasing intrauterine system, a reversible and less invasive treatment, are at an increased risk of needing additional treatment compared with women who start with endometrial ablation. The results of this study will enable physicians to provide women with heavy menstrual bleeding with the evidence to make a well-informed decision between the 2 treatments.

The (cost) effectiveness of procedural sedation and analgesia versus general anaesthesia for hysteroscopic myomectomy, a multicentre randomised controlled trial: PROSECCO trial, a study protocol.

BACKGROUND: In women with abnormal uterine bleeding, fibroids are a frequent finding. In case of heavy menstrual bleeding and presence of submucosal type 0-1 fibroids, hysteroscopic resection is the treatment of first choice, as removal of these fibroids is highly effective. Hysteroscopic myomectomy is currently usually performed in the operating theatre. A considerable reduction in costs and a higher patient satisfaction are expected when procedural sedation and analgesia with propofol (PSA) in an outpatient setting is applied. However, both safety and effectiveness - including the necessity for re-intervention due to incomplete resection - have not yet been evaluated. METHODS: This study is a multicentre randomised controlled trial with a non-inferiority design and will be performed in the Netherlands. Women > 18 years with a maximum of 3 symptomatic type 0 or 1 submucosal fibroids with a maximum diameter of 3.5 cm are eligible to participate in the trial. After informed consent, 205 women will be randomised to either hysteroscopic myomectomy using procedural sedation and analgesia with propofol in an outpatient setting or hysteroscopic myomectomy using general anaesthesia in a clinical setting in the operating theatre. Primary outcome will be the percentage of complete resections, based on transvaginal ultrasonography 6 weeks postoperatively. Secondary outcomes are cost effectiveness, menstrual blood loss (Pictorial blood assessment chart), quality of life, pain, return to daily activities/work, hospitalization, (post) operative complications and re-interventions. Women will be followed up to one year after hysteroscopic myomectomy. DISCUSSION: This study may demonstrate comparable effectiveness of hysteroscopic myomectomy under procedural sedation and analgesia versus general anaesthesia in a safe and patient friendly environment, whilst achieving a significant cost reduction. TRIAL REGISTRATION: Dutch trial register, number NTR5357 . Registered 11th of August 2015.

Dendritic cells cross-talk with tumour antigen-specific CD8+ T cells, Vγ9γδT cells and Vα24NKT cells in patients with glioblastoma multiforme and in healthy donors.

The finding that dendritic cells (DCs) orchestrate innate and adaptive immune responses has stimulated research on harnessing DCs for developing more effective vaccines for DC therapy. The expression of cytomegalovirus (CMV) antigens in glioblastoma multiforme (GBM) presents a unique opportunity to target these viral proteins for tumour immunotherapy. Here, we demonstrate that Vγ9γδT cells, innate immune cells activated by zoledronate (Z) and Vα24 natural killer (Vα24NK) cells, innate/adaptive immune cells activated by α-galactosylceramide (G) can link innate and adaptive immunities through cross-talk with interferon (IFN) DCs from patients with glioblastoma multiforme (GBM) and healthy donors in a manner that can amplify the activation and proliferation of CMVpp65-specific CD8+ T cells. The IFN DCs derived from patients with GBM used in this study express lower levels of programmed cell death ligand (PD)-L1 and PD-L2 and higher levels of C-C receptor 7 (CCR7) than the most commonly used mature interleukin (IL)-4 DCs. The expression level of programmed cell death 1 (PD-1) on CD8+ T cells, including CMVpp65-specific CD8+ T cells, expanded by IFN DCs pulsed with the CMVpp65-peptide and Z plus G (IFN DCs/P+Z+G), was lower than that expanded by IFN DCs pulsed with the peptide alone (IFN DCs/P). Multi-functional T cells, including human leucocyte antigen (HLA)-A*0201-restricted CMVpp65-specific CD8+ T cells, Vγ9γδT cells and Vα24NKT cells, efficiently kill the HLA-A*0201-positive GBM cell line expressing CMVpp65 protein (T98G). These findings indicate that DC therapy using IFN DCs/P+Z+G and/or CTL therapy using CMVpp65-specific CD8+ T cells expanded by IFN DCs/P+Z+G may lead to a good clinical outcome for patients with GBM.

Laparoscopy or clinical follow-up to detect occult diaphragm injuries following left-sided thoracoabdominal stab wounds: A pilot randomized controlled trial.

BACKGROUND: The purpose of this study was to determine whether patients with left-sided thoracoabdominal (TA) stab wounds can be safely treated with clinical and chest X-ray follow up. METHOD: A prospective, randomized control study was conducted at Groote Schuur Hospital from September 2009 through to November 2014. Patients with asymptomatic left TA stab wounds included in the trial were randomized into two groups. Group A underwent diagnostic laparoscopy and Group B underwent clinical and radiological follow-up. RESULTS: Twenty-seven patients were randomized to Group A (N=27) and thirty-one to Group B (N=31). All patients were young males with a median age of 26 years (range 18 to 48). The incidence of occult diaphragm injury in Group A was 29%. All diaphragm injuries found at laparoscopy were repaired. The mean hospital stay for the patients in Group A was 5 days (SD 1.3), compared to a mean hospital stay of 2.9 days (SD, 1.5), in Group B (p < 0.001). All patients in Group B had normal chest X-rays at their last visit. The mean follow-up time was 24 months (median: 24; interquartile range: 1-40). There was no morbidity or mortality in Group B. CONCLUSION: Clinical and radiological follow-up are feasible and appear to be safe, in the short term, in patients who harbour occult diaphragm injuries after left TA stab wounds. Until studies showing the natural history of diaphragm injury in humans are available, laparoscopy should remain the gold standard in treatment.

The effect of emergency medical services response on outcome of trauma laparotomy at a Level 1 Trauma Centre in South Africa.

BACKGROUND: Due to resource constrained pre-hospital emergency medical services (EMSs) there is a significant delay in injured patients arriving at Groote Schuur Hospital Trauma Centre (GSHTC). The aim of the study was to examine the effectiveness of EMSs in transferring trauma patients to GSHTC. The effect of any delay to laparotomy from injury was noted. METHOD: A prospective audit of patients presented directly from the scene to GSHTC following abdominal trauma over a four-month period was performed. Time from contact to the arrival of EMS at scene - the response time (RT) - was used as an indicator of EMS performance. Postoperative complications were graded according to Clavien-Dindo classification of surgical complications. RESULTS: A total of 118 patients were admitted to the trauma surgery ward following abdominal trauma. The mechanism was penetrating 101 (85.6%) [stab wounds in 67 (56.8%) and gunshot in 34 (28.8%)], and 17 (14.4%) with blunt injuries. EMSs transported 110 (93.2%) patients. A total of 48 index laparotomies were done during this period, of which 13 patients developed postoperative complications. The median RT of the EMS after contact was 53 min for patients who developed complications. It was significantly longer than for those without complications, 21 min (p < 0.01). The median delay to laparotomies from injury for patients with postoperative complications was 10.3 hours and for those without complications was 7.5 hours. The delay from injury to the theatre was also a significant factor in the development of complications (p = 0.02). CONCLUSION: The response delay by EMS and delay from injury to the theatre increased complications. Therefore, rapid response by EMS in transferring trauma patients needs to be strengthened.

Trauma unit attendance: Is there a relationship with weather, sporting events and week/ month-end times? An audit at an urban tertiary trauma unit in Cape Town.

BACKGROUND: The Groote Schuur Hospital Trauma Unit is a high-volume referral center where patient volumes may be related to temporal and environmental factors. OBJECTIVE: This audit aimed to determine if numbers of patients presenting after motor vehicle collisions (MVCs) and interpersonal violence (IPV) were related to temporal factors, weather variables and important soccer matches. METHOD: Numbers of patients presenting to the unit per shift over 17 months were obtained from unit logs. Weather data, local soccer match locations and results, and information regarding public holidays and long weekends were obtained for the relevant shifts. Average daily attendances for IPV-related injuries and MVCs were compared across the various external factors described. Poisson regression models were fitted and used to express the relative incidence of attendances. These results are expressed using incidence rate ratios (IRRs). RESULTS: For the study period, 7 350 attendances due to IPV-related injuries, and 3 188 injuries due to MVCs were recorded. Weekdays, long-weekend nights and month-end weekends had increased MVC-related attendance. Precipitation also increased attendances related to MVCs. Public holidays had less MVC-related attendance. IPV-related attendances were increased at night, on long weekends, and on month-end weekends. Weekend shifts were busier than weekday shifts, particularly at month-end. Long weekends showed similar trends to ordinary weekends, and public holidays showed similar trends to ordinary weekdays. Increasing temperatures are associated with increased attendances. Soccer matches and their outcomes have no significant effect on IPV-related attendances. CONCLUSION: Temporal and weather factors can help predict which trauma unit shifts will be busiest.

An urban trauma centre experience with abdominal vena cava injuries.

BACKGROUND: The aim of the study was to present the surgical management of injuries to the abdominal vena cava (AVC) and to identify clinical and physiological factors and management strategies which affect the outcome. METHOD: A retrospective review was conducted of AVC injuries in patients attending the trauma centre at Groote Schuur Hospital, Cape Town, from January 2003 to December 2011. Demographic data, mechanism and agent of injury, level of injury, physiological parameters, associated injuries, trauma scores, management strategy, morbidity and mortality, and length of hospital stay were taken from the trauma centre's operative databank at Groote Schuur Hospital. RESULTS: Thirty-fi ve patients with AVC injuries were identifi ed. There were 33 penetrating injuries (94%). Gunshot wounds accounted for 28 of them (85%). There were 19 (54%) infrarenal, 9 (26%) juxtarenal, 3 (7%) suprarenal and 4 (11%) retrohepatic AVC injuries. Most patients were treated with ligation (66%). There were 17 (49%) deaths. There were signifi cant differences in the preoperative systolic blood pressure (p = 0.044), number of red cell units transfused (p = 0.001), serum lactate (p = 0.007), arterial pH (p = 0.002) and preoperative temperature (p = 0.000) between the survivors and non-survivors. There was also a signifi cant difference in ligation versus repair between the two groups (p = ≤ 0.000). There was no difference in the injury severity, level of injury and the number of associated injuries between survivors and non-survivors. CONCLUSION: AVC injuries are associated with high mortality. Patients presenting with clinical and physiological evidence of shock and who require "damage control" surgery are more likely to suffer a worse outcome, particularly when multiple physiological deragements are present. Patients who died often have severe associated injuries.

Enhanced recovery after surgery (ERAS) in penetrating abdominal trauma: A prospective single-center pilot study.

BACKGROUND: Enhanced recovery after surgery (ERAS) programmes employed in elective surgery have provided strong evidence for decreased lengths of hospital stay without increase in postoperative complications. The aim of this study was to explore the role and benefits of ERAS implemented in patients undergoing emergency laparotomy for penetrating abdominal trauma. METHOD: Institutional University of Cape Town Human Research Ethics Committee (UCT-HREC) approved study. A prospective cohort of 38 consecutive patients with isolated penetrating abdominal trauma undergoing emergency laparotomy were included in the study. The enhanced recovery protocols (ERPs) included: early urinary catheter removal, early nasogastric tube (NGT) removal, early feeding, early mobilisation/physiotherapy, early intravenous line removal and early optimal oral analgesia. This group was compared to a historical control group of 40 consecutive patients undergoing emergency laparotomy for penetrating abdominal trauma, prior to the introduction of the ERP. Demographics, mechanism of injury, injury severity scores (ISS) and penetrating abdominal trauma index (PATI) were determined for both groups. The primary end-points were length of hospital stay (LOS) and incidence of postoperative complications (Clavien-Dindo classification) in the 2 groups. The difference in means was tested using the t-test assuming unequal variances. Statistical significance was defined as p-value less than 0.05 (p < 0.05). RESULTS: The two groups were comparable with regards to age, gender, mechanism of injury, ISS and PATI scores. The mean time to solid diet, urinary catheter and nasogastric tube (NGT) removal was 3.6 (non-ERAS) and 2.8 (ERAS) days [p < 0.035], 3.3 (non-ERAS) and 1.9 (ERAS) days [p < 0.00003], 2.1 (non-ERAS) and 1.2 (ERAS) days [p < 0.0042], respectively. There was no difference in time from admission to time of laparotomy 313 (non-ERAS) vs 358 (ERAS) minutes [p < 0.07]. There were 11 and 12 complications in the non-ERAS and ERAS groups, respectively. When graded as per the Clavien-Dindo classification, there was no significant difference in the 2 groups (p < 0.59). Hospital stay was significantly shorter in the ERAS group: 5.5 (SD 1.8) days vs. 8.4 (SD 4.2) days [p < 0.00021]. CONCLUSION: This pilot study shows that ERPs can be successfully implemented with significant shorter hospital stays without any increase in postoperative complications in trauma patients undergoing emergency laparotomy for penetrating abdominal trauma.

Endoscopic and operative treatment of delayed complications after pancreatic trauma: An analysis of 27 civilians treated in an academic Level 1 Trauma Centre.

BACKGROUND: This study evaluated the efficacy of endoscopic treatment of delayed local complications including pseudocysts and persistent pancreatic fistulae in a cohort of civilian patients who had previously sustained a pancreatic injury. METHOD: A large institutional database was interrogated to identify patients who developed a delayed pancreatic complication among those with pancreatic injuries treated between January 1990 and December 2013. The degree of the pancreatic duct injury was graded using a new duct injury grading system and endoscopic therapeutic outcome assessed according to the grade of injury. RESULTS: During the period under review, 432 consecutive patients were treated for pancreatic injuries of whom 27 (20 men, 7 women, median age 31, range 15-68 years) presented with delayed complications related to the initial pancreatic injury. Sixteen patients had non-resolving symptomatic pancreatic pseudocysts, 10 had persistent pancreatic fistulae and 1 had a symptomatic duct stricture. Fourteen patients with grade 2a, 3a, 3b or 4c main pancreatic duct injuries were successfully treated endoscopically with either pancreatic duct stenting or pseudocyst drainage while 13 patients with grade 4a or 4b duct injuries who had complete duct division with a disconnected duct syndrome failed endoscopic management and required surgical intervention. The 27 patients underwent a total of 49 endoscopic procedures (47 elective, 2 emergency) of whom 4 developed complications related to the endoscopic treatment. All 4 resolved, 2 after urgent endoscopic re-intervention. CONCLUSION: In this preliminary analysis the Cape Town pancreatic ductal injury grading classification showed a close correlation with outcome after endoscopic and operative intervention.

A practical guide to expedition medical planning.

Expedition medical planning is integral in ensuring participant safety and maximising the likelihood of achieving the expedition aims. The task of producing a medical plan will often fall to a medical officer of limited experience. The aim of this article is to provide a concise, practical guide to aid junior medical officers (MOs) in forming a robust and pragmatic medical plan.

Outcomes of non-operative management of penetrating abdominal trauma.

BACKGROUND: Selective non-operative management (SNOM) of penetrating abdominal trauma (PAT) is routinely practised in our trauma centre. This study aims to report the outcomes of patients who have failed SNOM. METHODS: Patients presenting with PAT from 1 May 2015 - 31 January 2018 were reviewed. They were categorised into immediate laparotomy and delayed operative management (DOM) groups. Outcomes compared were postoperative complications, length of hospital stay and mortality. RESULTS: A total of 944 patients with PAT were reviewed. After excluding 100 patients undergoing damage control surgery, 402 (47.6%) and 542 (52.4%) were managed non-operatively and operatively, respectively. In the SNOM cohort, 359 (89.3%) were managed successfully without laparotomy. Thirty-seven (86.0%) patients in the DOM group had a therapeutic laparotomy, and six (14.0%) had an unnecessary laparotomy. Nine (20.9%) patients in the DOM group developed complications. The DOM group had lesser complications. However, the two groups had no difference in hospital length of stay (LOS). There was no mortality in the non-operative management (NOM) group. CONCLUSION: In this study, we demonstrated no mortality and less morbidity in the DOM group when appropriately selected compared to the immediate laparotomy group. This supports the selective NOM approach for PAT in high volume trauma centres.

Psychometric network analysis of the Patient Health Questionnaire-4 (PHQ-4) in Paraguayan general population.

BACKGROUND: Depression and anxiety are two of the most prevalent and disabling mental disorders worldwide, both in the general population and in outpatient clinical settings. OBJECTIVE: This study aimed to analyze the psychometric properties of the Patient Health Questionnaire-4 (PHQ-4) based on network analysis metrics. METHODS: A total of 911 Paraguayans (23.71% women and 76.29% men; mean age 31.25 years, SD = 10.63), selected by non-probabilistic convenience sampling, participated in the study. Network analysis was used to evaluate the internal structure, reliability, and measurement invariance between men and women. RESULTS: The results revealed that the PHQ-4 is a unidimensional measure through Exploratory Graph Analysis (EGA). Reliability, through structural consistency, identified that 100% of the time, only a single dimension was obtained, and all items remained stable, as they were always replicated within the empirical dimension. The unidimensional structure has shown evidence of configural invariance; therefore, the network structure functioned equally among the different sex groups. CONCLUSION: The PHQ-4 presented optimal preliminary evidence of validity based on its internal structure, reliability, and invariance between sexes. Therefore, it may be useful as an accurate and brief measure of anxiety and depressive symptoms in the Paraguayan context.

Pandemic Grief and Suicidal Ideation in Latin American Countries: A Network Analysis.

This study aimed to characterize the network structure of pandemic grief symptoms and suicidal ideation in 2174 people from eight Latin American countries. Pandemic grief and suicidal ideation were measured using the Pandemic Grief Scale and a single item, respectively. Network analysis provides an in-depth characterization of symptom-symptom interactions within mental disorders. The results indicated that, "desire to die," "apathy" and "absence of sense of life" are the most central symptoms in a pandemic grief symptom network; therefore, these symptoms could be focal elements for preventive and treatment efforts. Suicidal ideation, the wish to die, and the absence of meaning in life had the strongest relationship. In general, the network structure did not differ among the participating countries. It identifies specific symptoms within the network that may increase the likelihood of their co-occurrence and is useful at the therapeutic level.

Subxiphoid pericardial window to exclude occult cardiac injury after penetrating thoracoabdominal trauma.

BACKGROUND: An occult cardiac injury may be present in patients with an acute abdomen after penetrating thoracoabdominal trauma. This study assessed the use of a subxiphoid pericardial window (SPW) as a diagnostic manoeuvre in this setting. METHODS: This was a retrospective review of a trauma database (2001-2009). Patients presenting with a penetrating thoracoabdominal injury with an acute abdomen, and in whom there was concern about a potential cardiac injury from the site or tract of the injury, were included. RESULTS: Fifty patients with an indication for emergency laparotomy underwent a SPW for a possible cardiac injury. An occult haemopericardium was present at SPW in 14 patients (28 per cent) mandating, median sternotomy. Nine cardiac injuries (18 per cent) were identified including five tangential injuries and four perforations. The specific complication rate relating to the SPW was 2 per cent. CONCLUSION: The SPW is a useful technique at laparotomy to identify cardiac injuries in patients with penetrating thoracoabdominal injuries.

Levonorgestrel releasing intrauterine system (Mirena) versus endometrial ablation (Novasure) in women with heavy menstrual bleeding: a multicentre randomised controlled trial.

BACKGROUND: Heavy menstrual bleeding is an important health problem. Two frequently used therapies are the levonorgestrel intra-uterine system (LNG-IUS) and endometrial ablation. The LNG-IUS can be applied easily by the general practitioner, which saves costs, but has considerable failure rates. As an alternative, endometrial ablation is also very effective, but this treatment has to be performed by a gynaecologist. Due to lack of direct comparison of LNG-IUS with endometrial ablation, there is no evidence based preferred advice for the use of one of these treatment possibilities. METHOD/DESIGN: A multicenter randomised controlled trial, organised in a network infrastructure in the Netherlands in which general practitioners and gynaecologists collaborate. DISCUSSON: This study, considering both effectiveness and cost effectiveness of LNG-IUS versus endometrial ablation may well improve care for women with heavy menstrual bleeding. TRIAL REGISTRATION: Dutch trial register, number NTR2984.

Temporary vascular shunting in vascular trauma: a 10-year review from a civilian trauma centre.

BACKGROUND: Temporary intravascular shunts (TIVSs) can replace immediate definitive repair as a damage control procedure in vascular trauma. We evaluated their use in an urban trauma centre with a high incidence of penetrating trauma. METHOD: A retrospective chart review of all patients treated with a TIVS in a single centre between January 2000 and December 2009. RESULTS: Thirty-five TIVSs were placed during the study period: 22 were part of a damage control procedure, 7 were inserted at a peripheral hospital without vascular surgical expertise prior to transfer, and 6 were used during fixation of a lower limb fracture with an associated vascular injury. There were 7 amputations and 5 deaths, 4 of the TIVSs thrombosed, and a further 3 dislodged or migrated. Twenty-five patients underwent definitive repair with an interposition graft, 1 primary anastomosis was achieved, and 1 extra-anatomical bypass was performed. Five patients with non-viable limbs had the vessel ligated. CONCLUSIONS: A TIVS in the damage control setting is both life- and limb-saving. These shunts can be inserted safely in a facility without access to a surgeon with vascular surgery experience if there is uncontrollable bleeding or the delay to definitive vascular surgery is likely to be more than 6 hours. A definitive procedure should be performed within 24 hours.

The impact of thromboelastography on patients with penetrating abdominal trauma requiring intensive care.

BACKGROUND: Trauma-induced coagulopathy (TIC) is a complex multifaceted process which contributes to higher mortality rates in severely injured trauma patients. Thromboelastography (TEG) is effective in detecting TIC which assists in instituting goal-directed therapy as part of damage control resuscitation. METHODS: This retrospective study included all adult patients over a 36-month period with penetrating abdominal trauma who required a laparotomy, blood products and admission for critical care. Analysis included demographics, admission data, 24-hour interventions, TEG parameters and 30-day outcomes. RESULTS: Eighty-four patients with a median age of 28 years were included. The majority (93%; 78/84) suffered from a gunshot injury, with 75% (63/84) receiving a damage control laparotomy. Forty-eight patients (57%) had a TEG. Injury severity score and total fluid and blood product administered in the first 24 hours were all significantly higher in patients who had a TEG (p < 0.05). TEG profiles were: 42% (20/48) normal, 42% (20/48) hypocoagulable, 12% (6/48) hypercoagulable and 4% (2/48) mixed parameters. Fibrinolysis profiles were: 48% (23/48) normal, 44% (21/48) fibrinolysis shutdown and 8% (4/48) hyperfibrinolysis. Mortality rate was 5% (4/84) at 24 hours and 26% (22/84) at 30 days, with no difference between the two groups. High-grade complication rates, days on a ventilator and intensive care unit length of stay were all significantly higher in patients who did not have a TEG. CONCLUSION: TIC is common in severely injured penetrating trauma patients. The usage of a thromboelastogram did not impact on 24-hour or 30-day mortality but did result in a decreased intensive care stay and a decreased high-grade complication rate.

Spectrum of coagulation profiles in severely injured patients - a subgroup analysis from the fluids in resuscitation of severe trauma trial.

BACKGROUND: Trauma-induced coagulopathy (TIC) is a major contributing factor to worsening bleeding in trauma patients. The objective of this study is to describe the spectrum of coagulation profiles amongst severely injured patients. METHODS: This is a retrospective study of all patients with complete baseline TEG coagulation parameters collected prior to randomisation in the FIRST (fluids in resuscitation of severe trauma) trial between January 2007 and December 2009. Parameters recorded for this study included patient demographics, mechanism of injury, admission vital signs, lactate, base excess, coagulation studies prothrombin time (PT), international normalised ratio (INR), thromboelastography (TEG) parameters, volume, and type of fluids administered, volume of blood products administered, length of intensive care unit (ICU) stay and major outcomes. RESULTS: A total of 87 patients were included in this study, with a median injury severity score (ISS) of 20 and 57.5 had a penetrating injury mechanism. Coagulopathy was highly prevalent in this cohort, of which a majority (69%) was diagnosed with hypercoagulopathy and 24% had a hypocoagulopathy status on admission. There was no difference in age, gender and amount of pre-hospital fluids administered across the three groups. The median volume of blood products was higher in the hypocoagulopathy group, although not statistically significant. Overall, the 30-day mortality rate was 13%, with case fatalities occurring in only coagulopathic patients: hypercoagulopathy (15%) and hypocoagulopathy (10%). CONCLUSION: TIC is not an infrequent diagnosis in severely injured patients resulting in increased morbidity and mortality. Determining the coagulation profile using TEG at presentation in this group of patients may inform appropriate management guidelines in order to improve outcome.
