Perioperative Care for Children With Syndromic Craniofacial Synostosis Undergoing Le Fort III Surgery: A Retrospective Cohort Study.

OBJECTIVE: To present characteristics, surgical variables, complications, and postoperative care in pediatric patients with craniofacial synostosis undergoing Le Fort III osteotomy. BACKGROUND: Craniofacial synostoses are a group of genetic syndromes that result in premature fusion of cranial and facial sutures, leading to craniofacial deformities and associated complications. Midface advancement through Le Fort III osteotomy is the most frequent surgical option for these conditions. METHODS: Retrospective monocentric cohort study including patients with syndromic craniofacial synostosis who underwent Le Fort III osteotomy between 2009 and 2022 in a specialized referral center. Data collection encompassed surgical time, blood loss, intraoperative transfusions, fluid balance, and postoperative parameters such as duration of invasive mechanical ventilation and intensive care unit (ICU) length of stay. RESULTS: Twenty-six children were included in the analysis. The median surgical time was 345 minutes (300-360), with an estimated blood loss of 15 (9.9-24) mL/kg. Patients required a median transfusion of 12.63 (7.1-24.5) mL/kg of packed red blood cells and 19.82 (11.1-33) mL/kg of fresh frozen plasma. Intraoperative fluid balance was + 12.5 (0.8-22.8) mL/kg, with a median infusion of 30.4 (23.9-38.7) mL/kg of crystalloids. All patients were transferred to the ICU after surgery to ensure a safe environment for extubation. The median duration of mechanical ventilation in the ICU was 30 (20.25-45) hours, and postoperative ICU length of stay was 2 (2-4) days, and complications were infrequent, with only one extubation failure recorded. CONCLUSION: Le Fort III osteotomy in craniofacial synostosis patients may be characterized by a complex perioperative course. A multidisciplinary approach in the care of these patients allows for minimizing complications in the perioperative phase. Further research is needed to enhance perioperative management in this unique patient population.

Determinants of increased nursing workload in the COVID-era: A retrospective analysis of prospectively collected data.

BACKGROUND: COVID-19 is associated with increased nursing workload, therefore a high nurse-to-patient ratio would be required. AIM: To analyse difference in nursing workload, as expressed with the Nursing Activities Score (NAS), between COVID-19 patients versus control patients without COVID-19 disease (NCOVID-19 group) in an Italian Extracorporeal Membrane Oxygenation (ECMO) centre. STUDY DESIGN: Retrospective analysis of prospectively collected data, enrolling consecutive patients admitted to a general Intensive Care Unit, between 1st May 2019 and 28th February 2021. A multivariate analysis was then performed to assess if COVID-19 disease was an independent predictor of higher NAS and to assess which other factors and procedures are independently associated with increased workload. RESULTS: We enrolled 574 patients, of which 135 (24%) were in the COVID-19 group and 439 (76%) in the NCOVID-19 group. The average NAS was higher in the COVID-19 group (79 ± 11 vs. 65 ± 15, T = -10.026; p < 0.001). Prone positioning, continuous renal replacement therapy (CRRT) and ECMO were used more frequently in the COVID-19 group. A higher fraction of patients in the COVID group showed colonization from multidrug resistant bacteria. COVID-19 group had a higher duration of mechanical ventilation and longer ICU stay. The COVID-19 diagnosis was independently associated with a higher NAS. Other independent predictors of higher NAS were the use of prone positioning and continuous renal replacement therapy (CRRT). Colonization from multidrug resistant bacteria and ECMO support were not independently associated with higher NAS. CONCLUSIONS: The higher nursing workload in COVID-19 patients is mainly due to specific procedures required to treat the most hypoxemic patients, such as prone positioning. Colonization with multidrug resistant bacteria and ECMO support were not independently associated with a higher NAS. RELEVANCE TO CLINICAL PRACTICE: Higher workload in COVID-19 patients was due to specific interventions, such as prone positioning and CRRT, with the related nursing activities, as continuous presence at patient's bed, mobilization, positioning and complex hygienic procedures.

Problem drinking recognition among UK military personnel: prevalence and associations.

PURPOSE: Despite the higher prevalence of problem drinking in the UK military compared to the general population, problem recognition appears to be low, and little is known about which groups are more likely to recognise a problem. This study examined prevalence of problem drinking recognition and its associations. METHODS: We analysed data from 6400 regular serving and ex-serving personnel, collected in phase 3 (2014-2016) of the King's Centre for Military Health Research cohort study. MEASUREMENTS: Participants provided sociodemographic, military, health and impairment, life experiences, problem drinking, and problem recognition information. Problem drinking was categorised as scores ≥ 16 in the AUDIT questionnaire. Associations with problem recognition were examined with weighted logistic regressions. FINDINGS: Among personnel meeting criteria for problem drinking, 49% recognised the problem. Recognition was most strongly associated (ORs ≥ 2.50) with experiencing probable PTSD (AOR = 2.86, 95% CI = 1.64-5.07), social impairment due to physical or mental health problems (AOR = 2.69, 95% CI = 1.51-4.79), adverse life events (AOR = 2.84, 95% CI = 1.70-4.75), ever being arrested (AOR = 2.99, CI = 1.43-6.25) and reporting symptoms of alcohol dependence (AOR = 3.68, 95% CI = 2.33-5.82). To a lesser extent, recognition was also statistically significantly associated with experiencing psychosomatic symptoms, feeling less healthy, probable common mental health disorders, and increased scores on the AUDIT. CONCLUSION: Half of UK military personnel experiencing problem drinking does not self-report their drinking behaviour as problematic. Greater problem drinking severity, poorer mental or physical health, and negative life experiences facilitate problem recognition.

Tracheal stenting on venovenous ECMO with a dual lumen right atrium-to-pulmonary artery cannula in a COVID-19 patient with an inferior vena cava filter.

A 47-year-old man, with no medical history, was diagnosed with severe COVID-19 ARDS and pulmonary embolism. Venovenous extracorporeal membrane oxygenation (ECMO) was required for impossibility to deliver protective ventilation. The patient was weaned from ECMO after clinical improvement. An inferior vena cava filter was then positioned to prevent embolization from a persistent left femoral deep venous thrombosis. Two days after the ECMO removal, a large lesion of the tracheal posterior wall was diagnosed. Tracheal stenting was deemed necessary. ECMO support was then re-established, to safely perform the bronchoscopic procedure. Due to the presence of the inferior vena cava filter, the patient was cannulated via the right internal jugular vein with a double lumen ProtekDuo cannula. The patient was then weaned from ECMO support and invasive ventilation. The tracheal stent was removed after 40 days, showing a full recovery of the tracheal lesion. The patient was discharged home in good condition.

How to avoid rapid carbon dioxide changes at the start of veno-venous extracorporeal membrane oxygenation: Role of end-tidal CO2 monitoring.

Background: Venovenous ECMO is a lifesaving technique for patients with severe respiratory failure. Management of carbon dioxide (CO2) levels at ECMO start is crucial, as recent studies found an association between rapid CO2 shifts and increased incidence of neurological complications.Purpose: To describe the role of end tidal CO2 (etCO2) monitoring at the ECMO start to minimize carbon dioxide shifts.Research design: Retrospective cohort study.Methods: We performed a retrospective analysis of patients who started venovenous ECMO support at our institution between 2011 and 2021. We analysed the minute-by-minute variations of etCO2, ventilatory parameters and arterial blood gas before and after the ECMO start.Results: 36 patients with a complete dataset of parameters were included. After the ECMO start, minute ventilation was progressively reduced from 10.8±;3.3 to 2.9±1.2 L/min (p<0.001). etCO2 did not vary significantly (baseline 37±10 vs 35±9 mmHg 20 minutes after ECMO start, p = 0.36). Despite a stable etCO2 level, a mild drop of arterial CO2 tension (9.5 mmHg, corresponding to a 18% change) was recorded at the first ABG sampled after the ECMO start. No patient developed neurological complications after the ECMO commencement.Conclusion: etCO2 monitoring during ECMO start is feasible and allows to adjust gas flow and ventilator settings to limit changes in arterial CO2 levels.

Recruiting Military Veterans into Alcohol Misuse Research: The Role of Social Media and Facebook Advertising.

Background: The use of digital technology within health care service delivery, monitoring, and research is becoming progressively popular, particularly given the ongoing COVID-19 pandemic. Mobile health (m-health) apps, one form of digital technology, are increasingly being used to promote positive health related behavior change. Therefore, it is important to conduct research to understand the efficacy of m-health apps. The process of participant recruitment is an essential component in producing strong research evidence, along with ensuring an adequately powered sample to conduct meaningful analyses and draw robust conclusions. Methods: In this work we outline and reflect on the strategies used to recruit help-seeking military veterans into an intervention study, which aimed to evaluate the efficacy of an app (Drinks:Ration) to modify behavior in alcohol misusers. Recruitment strategies included through (1) partner organizations and (2) social media and Facebook advertising (ads). Results: Facebook ads were live for a period of 88 days and were viewed by a total audience of 29,416 people. In total 168 military veterans were recruited across all recruitment strategies, meaning that Drinks:Ration exceeded its recruitment targets. Half of the sample (n = 84) were recruited through social media, including Facebook ads. Conclusions: The current article highlighted that targeted Facebook ads were an efficient strategy to recruit military veterans into a digital intervention trial aiming to reduce alcohol consumption because they reduced the amount of time and resources required to contact a large number of potentially eligible individuals for our study. This article acts as a starting point for other researchers to evaluate their recruitment pathways for recruiting military veterans into alcohol misuse research.

The role of intensive care unit diaries in the grieving process: A monocentric qualitative study.

BACKGROUND: The growing importance of psychological recovery for patients and their families following intensive care unit (ICU) experiences in recent years cannot be overemphasized. The ICU diary is used to aid patients in reducing the prevalence of post-traumatic stress disorder, anxiety, and depression. The usefulness of maintaining a diary during the grieving process has not yet been thoroughly investigated. AIM: To investigate the role of ICU diaries in the grief process experienced by family members of a person who died in the intensive care unit. STUDY DESIGN: Nine family members of seven deceased ICU patients with an ICU diary were contacted and interviewed by phone using a semi-structured interview. A qualitative data analysis was performed using thematic synthesis. SETTING: Italian general intensive care unit. FINDINGS: Interviewed family members felt that the diary helped them during the grieving process. The return of diaries was desired by family members for support and to remember one's loved one. The diary helped them process their losses in various ways, including signs of evidence of care, emotional involvement, consideration, and coping with grief. Four main themes emerged from the analysis: writing the diary, reading the diary, talking about the diary, and the diary during the grieving process. CONCLUSIONS: The overall perception of the ICU diary was positive. The diary mostly helped relatives to "give back something of what we lost". This study also affirms the positive link between ICU diaries and bereavement in Italian ICU. Further studies are required to confirm the usefulness of this tool in the grieving process. RELEVANCE TO CLINICAL PRACTICE: The ICU diary can help patients' family members understand what happened to their loved one and play an important role in the grieving process. The diary served as a valuable source of information that aided in providing bereavement support to the family by helping them to gain a rational and emotional understanding of the patient's death.

Smartphone-based alcohol interventions: A systematic review on the role of notifications in changing behaviors toward alcohol.

Background: Smartphone-based interventions are increasingly being used to facilitate positive behavior change, including reducing alcohol consumption. However, less is known about the effects of notifications to support this change, including intervention engagement and adherence. The aim of this review was to assess the role of notifications in smartphone-based interventions designed to support, manage, or reduce alcohol consumption. Methods: Five electronic databases were searched to identify studies meeting inclusion criteria: (1) studies using a smartphone-based alcohol intervention, (2) the intervention used notifications, and (3) published between 1st January 2007 and 30th April 2021 in English. PROSPERO was searched to identify any completed, ongoing, or planned systematic reviews and meta-analyses of relevance. The reference lists of all included studies were searched. Results: Overall, 14 papers were identified, reporting on 10 different interventions. The strength of the evidence regarding the role and utility of notifications in changing behavior toward alcohol of the reviewed interventions was inconclusive. Only one study drew distinct conclusions about the relationships between notifications and app engagement, and notifications and behavior change. Conclusions: Although there are many smartphone-based interventions to support alcohol reduction, this review highlights a lack of evidence to support the use of notifications (such as push notifications, alerts, prompts, and nudges) used within smartphone interventions for alcohol management aiming to promote positive behavior change. Included studies were limited due to small sample sizes and insufficient follow-up. Evidence for the benefits of smartphone-based alcohol interventions remains promising, but the efficacy of using notifications, especially personalized notifications, within these interventions remain unproven.

Cost of post-deployment screening for mental illness in the UK military: findings from a cluster randomised controlled trial.

BACKGROUND: Little is known about the economic impact of military mental health screening. AIMS: To investigate (a) whether post-deployment screening of military personnel affects use and cost of services and (b) the impact of psychiatric morbidity on costs. METHODS: Participants were recruited from UK Royal Marine and Army platoons and randomised to an intervention group (which received tailored advice predicated upon mental health status) or a control group (which received general advice following assessment of mental health status). The intervention costs were calculated while service use and associated costs were assessed at 12-month follow-up. RESULTS: Data were available for 6323 participants. Mean screening cost was £34. Service costs were slightly higher in the control group compared to the intervention group (£1197 vs. £1147) which was not statistically significant (bootstrapped 95%CI, -£363 to £434. In both groups, screening and control, costs were significantly higher for those who screened positive for mental health problems. CONCLUSIONS: Costs were not affected by screening. In countries that have already implemented post-deployment screening, the political cost of disinvestment needs careful consideration. Those who develop psychiatric morbidity have substantially higher care costs than those who do not.

Prone position in intubated, mechanically ventilated patients with COVID-19: a multi-centric study of more than 1000 patients.

BACKGROUND: Limited data are available on the use of prone position in intubated, invasively ventilated patients with Coronavirus disease-19 (COVID-19). Aim of this study is to investigate the use and effect of prone position in this population during the first 2020 pandemic wave. METHODS: Retrospective, multicentre, national cohort study conducted between February 24 and June 14, 2020, in 24 Italian Intensive Care Units (ICU) on adult patients needing invasive mechanical ventilation for respiratory failure caused by COVID-19. Clinical data were collected on the day of ICU admission. Information regarding the use of prone position was collected daily. Follow-up for patient outcomes was performed on July 15, 2020. The respiratory effects of the first prone position were studied in a subset of 78 patients. Patients were classified as Oxygen Responders if the PaO2/FiO2 ratio increased ≥ 20 mmHg during prone position and as Carbon Dioxide Responders if the ventilatory ratio was reduced during prone position. RESULTS: Of 1057 included patients, mild, moderate and severe ARDS was present in 15, 50 and 35% of patients, respectively, and had a resulting mortality of 25, 33 and 41%. Prone position was applied in 61% of the patients. Patients placed prone had a more severe disease and died significantly more (45% vs. 33%, p < 0.001). Overall, prone position induced a significant increase in PaO2/FiO2 ratio, while no change in respiratory system compliance or ventilatory ratio was observed. Seventy-eight % of the subset of 78 patients were Oxygen Responders. Non-Responders had a more severe respiratory failure and died more often in the ICU (65% vs. 38%, p = 0.047). Forty-seven % of patients were defined as Carbon Dioxide Responders. These patients were older and had more comorbidities; however, no difference in terms of ICU mortality was observed (51% vs. 37%, p = 0.189 for Carbon Dioxide Responders and Non-Responders, respectively). CONCLUSIONS: During the COVID-19 pandemic, prone position has been widely adopted to treat mechanically ventilated patients with respiratory failure. The majority of patients improved their oxygenation during prone position, most likely due to a better ventilation perfusion matching. TRIAL REGISTRATION: clinicaltrials.gov number: NCT04388670.

Contribution of mental ill health during military service to postservice benefit claims in the UK.

OBJECTIVES: While most UK military personnel transition successfully into civilian life, some experience unemployment and disability, which may be partly attributable to in-service factors. This study aims to determine the degree to which in-service mental health problems impact on postservice benefit claims. METHODS: Using data from a cohort of 5598 recent leavers from regular service in the UK Armed Forces linked with data from the Department for Work and Pensions, we assessed associations between in-service mental health and postservice benefit claims, and the population attributable fraction (PAF) of benefit claims related to in-service mental health. An analysis with postservice mental ill health as mediator was performed to determine the degree to which the observed effects were a consequence of persistent illness, as opposed to remitted. RESULTS: Mental illness occurring in-service predicted both unemployment and disability claims, partly mediated by postservice health (23%-52% total effects mediated), but alcohol misuse did not. Common mental disorder (CMD) (PAF 0.07, 95% CI: 0.02 to 0.11) and probable post-traumatic stress disorder (PTSD) (PAF 0.05, 95% CI 0.01 to 0.09) contributed to unemployment claims. Probable PTSD was the largest contributor to disability claims (PAF 0.25, 95% CI 0.13 to 0.36), with a smaller contribution from CMD (PAF 0.16, 95% CI 0.03 to 0.27). CONCLUSIONS: In-service mental ill health gives rise to benefit claims. These effects are only partly mediated by postservice mental health, implying that in-service (or pre-service) mental issues have carry-over effects into civilian life even if remitted. Better prevention and treatment of in-service PTSD symptoms may well reduce postservice disability claims.

A brief airway occlusion is sufficient to measure the patient's inspiratory effort/electrical activity of the diaphragm index (PEI).

Pressure generated by patient's inspiratory muscles (Pmus) during assisted mechanical ventilation is of significant relevance. However, Pmus is not commonly measured since an esophageal balloon catheter is required. We have previously shown that Pmus can be estimated by measuring the electrical activity of the diaphragm (EAdi) through the Pmus/EAdi index (PEI). We investigated whether PEI could be reliably measured by a brief end-expiratory occlusion maneuver to propose an automated PEI measurement performed by the ventilator. Pmus, EAdi, airway pressure (Paw), and flow waveforms of 12 critically ill patients undergoing assisted mechanical ventilation were recorded. Repeated end-expiratory occlusion maneuvers were performed. PEI was measured at 100 ms (PEI0.1) and 200 ms (PEI0.2) from the start of the occlusion and compared to the PEI measured at the maximum Paw deflection (PEIoccl, reference). PEI0.1 and PEI0.2 tightly correlated with PEIoccl, (p < 0.001, R2 = 0.843 and 0.847). At a patient-level analysis, the highest percentage error was -64% and 50% for PEI0.1 and PEI0.2, respectively, suggesting that PEI0.2 might be a more reliable measurement. After correcting the error bias, the PEI0.2 percentage error was lower than ± 30% in all but one subjects (range - 39 to + 29%). It is possible to calculate PEI over a brief airway occlusion of 200 ms at inspiratory onset without the need for a full patient's inspiratory effort. Automated and repeated brief airway occlusions performed by the ventilator can provide a real time measurement of PEI; combining the automatically measured PEI with the EAdi trace could be used to continuously display the Pmus waveform at the bedside without the need of an esophageal balloon catheter.

Long-Term Correlates of Mild Traumatic Brain Injury on Postconcussion Symptoms After Deployment to Iraq and Afghanistan in the UK Military.

OBJECTIVES: We assessed whether mild traumatic brain injury (mTBI) reported by UK service personnel between 2007 and 2009 was associated with postconcussion symptoms (PCS) 7 to 8 years later. SETTING: United Kingdom. PARTICIPANTS: A total of 4601 service personnel all of whom had deployed to Iraq and/or Afghanistan. DESIGN: Longitudinal study. MAIN OUTCOME MEASURES: Nine PCS reported in a survey carried out between 2014 and 2016. The main independent variable was mTBI reported between 2007 and 2009. RESULTS: A total of 2318 (50.4%) out of 4601 participants completed the follow-up questionnaire. Mild traumatic brain injury was associated with 2 of 9 PCS. Mild traumatic brain injury at baseline was associated with dizziness at follow-up in the fully adjusted model, in comparison with either "other injury" or "no injury" group. Mild traumatic brain injury was associated with loss of concentration in comparison with "no injury" but in comparison with the "other injury" group, it was not in the fully adjusted model. The prevalence of 7 of the 9 PCS increased over time regardless of mTBI status. CONCLUSIONS: Mild traumatic brain injury reported in 2007-2009 was associated with dizziness and possibly with loss of concentration 7 years later but not with most PCS. The prevalence of most PCS increased over time independently of mTBI.

Unemployment and benefit claims by UK veterans in the new millennium: results from a record linkage study.

OBJECTIVES: In the first study of its kind in the UK, we linked pensions data on benefit claims with data from the King's Military Cohort to assess uptake of unemployment and disability benefits in military veterans of the UK Armed Forces. METHODS: Benefits data were matched with data on the mental health, demographics and military-related variables for 7942 veterans who had previously served as regulars and transitioned to civilian life between 2003 and 2016. Associations between demographic and service-related factors and benefit claims were assessed using Cox regression to take into account period at risk. RESULTS: Around 20% of veterans claim unemployment benefits (UB) shortly after leaving, but this proportion drops rapidly to around 2% in the first 2 years post service. Receipt of disability benefits (DB) is less common (1.5%), but longer-term. The most consistent predictors of postservice benefit usage were: low rank (a proxy for socio-economic status while in service) (HR 1.42 (95% CI 1.23 to 1.65) for UB and 1.59 (95% CI 1.11 to 2.27) for DB); leaving service (HR 1.29 (95% CI 1.07 to 1.56) between unplanned leaving and UB, and 7.51 (95% CI 5.31 to 10.6) between medical discharge and DB), and having a history of claiming benefits before joining the Services (HR 1.62 (95% CI 1.34 to 1.95) between preservice and postservice UB, and 2.86 (95% CI 1.09 to 7.47) between preservice and postservice DB). CONCLUSIONS: Benefit claims by veterans are largely driven by socioeconomic, rather than military, factors. Additional employment-focused support to Service leavers may be particularly useful to lower-ranked personnel and those leaving in an unplanned way. Continuity of care and medical oversight is a key concern for those with medical discharges.

Post-deployment screening for mental disorders and tailored advice about help-seeking in the UK military: a cluster randomised controlled trial.

BACKGROUND: The effectiveness of post-deployment screening for mental disorders has not been assessed in a randomised controlled trial. We aimed to assess whether post-deployment screening for post-traumatic stress disorder (PTSD), depression, anxiety, or alcohol misuse was effective. We defined screening as the presumptive identification of a previously unrecognised disorder using tests to distinguish those who probably had the disorder from those who probably did not so that those people with a probable disorder could be referred appropriately, and assessed effectiveness and consequences for help-seeking by the odds ratio at follow-up between those receiving tailored help-seeking advice and those who received general mental health advice. METHODS: We did a cluster randomised controlled trial among Royal Marines and Army personnel in the UK military after deployment to Afghanistan. Platoons were randomly assigned (1:1 initially, then 2:1) by stratified block randomisation with randomly varying block sizes of two and four to the screening group, which received tailored help-seeking advice, or the control group, which received general mental health advice. Initial assessment took place 6-12 weeks after deployment; follow-up assessments were done 10-24 months later. Follow-up measures were the PTSD Checklist-Civilian Version, Patient Health Questionnaire-9, Generalised Anxiety Disorder-7 scale, Alcohol Use Disorder Identification Test (AUDIT), and self-reported help-seeking from clinical and welfare providers comparing those receiving tailored advice and those receiving only general advice. All participants and all investigators other than the person who analysed the data were masked to allocation. The primary outcomes were PTSD, depression or generalised anxiety disorder, and alcohol misuse at follow-up. A key secondary outcome was assessment of whether post-deployment screening followed by tailored advice would modify help-seeking behaviour. Comparisons were made between screening and control groups, with primary analyses by intention to treat. This trial is registered with the ISRCTN Registry, number ISRCTN19965528. FINDINGS: Between Oct 24, 2011, and Oct 31, 2014, 434 platoons comprising 10 190 personnel were included: 274 (6350 personnel) in the screening group and 160 (3840 personnel) in the control group. 5577 (88%) of 6350 personnel received screening and 3996 (63%) completed follow-up, whereas 3149 (82%) of 3840 received the control questionnaire and 2369 (62%) completed follow-up. 1958 (35%) of 5577 personnel in the screening group declined to see the tailored advice, but those with PTSD (83%) or anxiety or depression (84%) were more likely than non-cases (64%) to view the advice (both p<0·0001). At follow-up, there were no significant differences in prevalence between groups for PTSD (adjusted odds ratio 0·92, 95% CI 0·75-1·14), depression or anxiety (0·91, 0·71-1·16), alcohol misuse (0·88, 0·73-1·06), or seeking support for mental disorders (0·92, 0·78-1·08). INTERPRETATION: Post-deployment screening for mental disorders based on tailored advice was not effective at reducing prevalence of mental health disorders nor did it increase help-seeking. Countries that have implemented post-deployment screening programmes for mental disorders should consider monitoring the outcomes of their programmes.

Mental health outcomes at the end of the British involvement in the Iraq and Afghanistan conflicts: a cohort study.

BACKGROUND: Little is known about the prevalence of mental health outcomes in UK personnel at the end of the British involvement in the Iraq and Afghanistan conflicts.AimsWe examined the prevalence of mental disorders and alcohol misuse, whether this differed between serving and ex-serving regular personnel and by deployment status. METHOD: This is the third phase of a military cohort study (2014-2016; n = 8093). The sample was based on participants from previous phases (2004-2006 and 2007-2009) and a new randomly selected sample of those who had joined the UK armed forces since 2009. RESULTS: The prevalence was 6.2% for probable post-traumatic stress disorder, 21.9% for common mental disorders and 10.0% for alcohol misuse. Deployment to Iraq or Afghanistan and a combat role during deployment were associated with significantly worse mental health outcomes and alcohol misuse in ex-serving regular personnel but not in currently serving regular personnel. CONCLUSIONS: The findings highlight an increasing prevalence of post-traumatic stress disorder and a lowering prevalence of alcohol misuse compared with our previous findings and stresses the importance of continued surveillance during service and beyond.

Prevalence of PTSD and other mental disorders in UK service personnel by time since end of deployment: a meta-analysis.

BACKGROUND: US studies have shown an increase of posttraumatic stress disorder (PTSD) and depression, but not alcohol misuse related to time of assessment since returning from deployment. We assessed if similar trends occur in the UK Armed Forces. METHODS: We selected UK studies based on our data base of King's Centre for Military Health Research publications from 2006 until January 2016 with at least one of the following measures: PTSD checklist-civilian version (PCL-C), the General Health Questionnaire (GHQ-12) and the Alcohol Use Disorders Identification Test (AUDIT). The studies included personnel assessed for these outcomes after their most recent deployment. A search in Medline, Psycho-Info and Embase confirmed that no relevant publication was missed. RESULTS: Twenty one thousand, seven hundred and forty-six deployed personnel from nine studies contributed to the meta-analyses by time since end of deployment in the PTSD analysis. The number of studies for period of time varied from two to four studies. The trend by time-category of questionnaire completion since returning from deployment were for PTSD ß = 0.0021 (95 % CI -0.00046 to 0.0049, p = 0.12), for psychological distress ß = 0.0123 (95 % CI 0.005 to 0.019, p = 0.002) and for alcohol misuse ß = 0.0013 (-0.0079 to 0.0105, p = 0.77). CONCLUSIONS: There was no evidence that the prevalence of PTSD and alcohol misuse changed according to time since the end of deployment over a three-year period, but there was evidence for an association with increasing psychological distress.

Changes in symptoms of asthma and rhinitis by sensitization status over ten years in a cohort of young Chilean adults.

BACKGROUND: We investigated the net changes in prevalence of symptoms of asthma and rhinitis over 10 years in a cohort of young by baseline sensitization status. METHODS: One thousand one hundred ninety three Chilean adults subjects aged 22-28 living in a semi-rural area of central Chile answered a lifestyle and the European Community Respiratory Health Survey (ECRHS) questionnaires. Bronchial hyper-responsiveness (BHR) and skin prick test (SPT) to eight allergens were measured at baseline in 2001. Ten years later, 772 participants completed the questionnaires again. Estimates of adjusted net changes in prevalence of symptoms by sensitization status at baseline and association between sensitization status at baseline and respiratory symptoms ten years later were assessed. RESULTS: A quarter of the participants were sensitized to at least one allergen in 2001. Prevalence of wheeze had a net change per year of -0.37 % (95 % Confidence Interval -0.71 to 0.02 %; p = 0.067). Self-reported nasal allergies in the last 12 months increased by 0.83 % per year (95 % CI 0.49 to 1.17 %; p < 0.001). Those sensitized to either cat fur (OR 1.76; CI 1.01 to 3.05), cockroach, (OR 2.09; 1.13 to 3.86) blend of grass and pollens (1.78; 95 % CI 1.08 to 2.92), or weeds (OR 1.77; 95 % CI 1.01 to 3.12) in 2001 were more likely to have wheeze in the last 12 months 10 years later. CONCLUSION: Symptoms of asthma remained stable or slightly changed over 10 years in adults, whilst rhinitis and nasal allergies greatly increased. Being sensitized to at least one allergen is a risk factor for persistent symptoms of asthma and rhinitis, but not for determining net changes of symptoms over time. The underlying causes for the contrasting trends between asthma and nasal allergy are unknown.

Aggressive and violent behavior among military personnel deployed to Iraq and Afghanistan: prevalence and link with deployment and combat exposure.

A systematic review and meta-analyses were conducted on studies of the prevalence of aggressive and violent behavior, as well as of violent offenses and convictions, among military personnel following deployment to Iraq and/or Afghanistan; the relationship with deployment and combat exposure; and the role that mental health problems, such as post-traumatic stress disorder (PTSD), have on the pathway between deployment and combat to violence. Seventeen studies published between January 1, 2001, and February 12, 2014, in the United States and the United Kingdom met the inclusion criteria. Despite methodological differences across studies, aggressive behavior was found to be prevalent among serving and formerly serving personnel, with pooled estimates of 10% (95% confidence interval (CI): 1, 20) for physical assault and 29% (95% CI: 25, 36) for all types of physical aggression in the last month, and worthy of further exploration. In both countries, rates were increased among combat-exposed, formerly serving personnel. The majority of studies suggested a small-to-moderate association between combat exposure and postdeployment physical aggression and violence, with a pooled estimate of the weighted odds ratio = 3.24 (95% CI: 2.75, 3.82), with several studies finding that violence increased with intensity and frequency of exposure to combat traumas. The review's findings support the mediating role of PTSD between combat and postdeployment violence and the importance of alcohol, especially if comorbid with PTSD.

Stigma as a barrier to seeking health care among military personnel with mental health problems.

Approximately 60% of military personnel who experience mental health problems do not seek help, yet many of them could benefit from professional treatment. Across military studies, one of the most frequently reported barriers to help-seeking for mental health problems is concerns about stigma. It is, however, less clear how stigma influences mental health service utilization. This review will synthesize existing research on stigma, focusing on those in the military with mental health problems. We conducted a systematic review and meta-analysis of studies between 2001 and 2014 to examine the prevalence of stigma for seeking help for a mental health problem and its association with help-seeking intentions/mental health service utilization. Twenty papers met the search criteria. Weighted prevalence estimates for the 2 most endorsed stigma concerns were 44.2% (95% confidence interval: 37.1, 51.4) for "My unit leadership might treat me differently" and 42.9% (95% confidence interval: 36.8, 49.0) for "I would be seen as weak." Nine studies found no association between anticipated stigma and help-seeking intentions/mental health service use and 4 studies found a positive association. One study found a negative association between self-stigma and intentions to seek help. Counterintuitively, those that endorsed high anticipated stigma still utilized mental health services or were interested in seeking help. We propose that these findings may be related to intention-behavior gaps or methodological issues in the measurement of stigma. Positive associations may be influenced by modified labeling theory. Additionally, other factors such as self-stigma and negative attitudes toward mental health care may be worth further attention in future investigation.
