- Abstract
n outcome evaluation was conducted to obtain psychiatric inpatients’ perspectives on acute care mental health treatment and services. The applicability of diagnostic categories based on affective, non-affective, and schizoaffective disorder were considered in the predictability of responses to treatment regimens and the related services provided in an inpatient psychiatric unit. A multidimensional approach was used to survey patients, which included the DAI-30, the BMQ, the SERVQUAL, and the CSQ-8. Overall, findings indicate that inpatient satisfaction could be improved with tailoring treatment to suit their respective symptoms. Furthermore, this exploratory study demonstrates some preliminary support for the inclusion of patients with a diagnosis of schizoaffective disorder as a separate group toward improving acute mental health care while hospitalized.

Abstract Background The role of IL-7 and pre-TCR signaling during T cell development has been well characterized in murine but not in human system. We and others have reported that human BM hematopoietic progenitor cells (HPCs) display poor proliferation, inefficient double negative (DN) to double positive (DP) transition and no functional maturation in the in vitro OP9-Delta-like 1 (DL1) culture system. Results In this study, we investigated the importance of optimal IL-7 and pre-TCR signaling during adult human T cell development. Using a modified OP9-DL1 culture ectopically expressing IL-7 and Fms-like tyrosine kinase 3 ligand (Flt3L), we demonstrated enhanced T cell precursor expansion. IL-7 removal at various time points during T cell development promoted a slight increase of DP cells; however, these cells did not differentiate further and underwent cell death. As pre-TCR signaling rescues DN cells from programmed cell death, we treated the culture with anti-CD3 antibody. Upon pre-TCR stimulation, the IL-7 deprived T precursors differentiated into CD3+TCRαβ+DP cells and further matured into functional CD4 T cells, albeit displayed a skewed TCR Vβ repertoire. Conclusions Our study establishes for the first time a critical control for differentiation and maturation of adult human T cells from HPCs by concomitant regulation of IL-7 and pre-TCR signaling.

- Abstract
The most common posterior mediastinal masses are neurogenic tumors such as peripheral nerve sheath tumors (PNST). Schwannomas, a subtype of PNST, are most often benign, well encapsulated tumors of neural crest cell origin, and are frequently incidentally found, ranging in size from small asymptomatic mediastinal tumors to large masses. Rarely, large schwannomas are discovered when symptoms develop due to compression or involvement of nearby structures leading to an array of possible sequela which can include, but not limited to, persistent cough, hemoptysis, and dysphagia. Management decisions are based off of tumor size, location, concern for underlying malignant pathology, and potential for complications related to tumor invasion of vital anatomical structures. A majority of the schwannomas undergo surgical resection, though a subset of small, asymptomatic, benign tumors on imaging or pathology may be managed with surveillance. This case report describes a large posterior mediastinal schwannoma adherent to the posterior aortic arch and encasing the left subclavian and vertebral arteries. Surgical resection required vascular resection of a segment of the left subclavian artery and graft reconstruction using polytetrafluoroethylene (PTFE). This report further highlights the importance of preoperative planning with consideration of a multidisciplinary approach in preparation for resection of large, complex posterior mediastinal masses., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/med-20-71).

- Abstract
Background: Recent support for centralization of complex operations, such as pancreaticoduodenectomy (PD), is based on surgeon-specific volume-outcome relationships. This study examined whether volume of anatomically related operations (operative mix), besides PD, is also independently associated with postoperative outcomes after PD., Methods: The study queried the Nationwide Inpatient Sample (2004-2009) for surgeons performing PD. Operative mix (OM) was defined as the year-specific number of other pancreatic, hepatic, biliary, and gastric operations performed by individual surgeons. Regression models included surgeon and hospital PD volume, adjusted for other hospital- and patient-specific factors., Results: Among 1747 surgeons, 88.3% had low PD volume (≤ 5 cases/year), 8.9% had moderate PD volume (6-16 cases/year), and 2.8% had high PD volume (≥ 17 cases/year). Low-PD-volume surgeons with high OM (≥ 21 cases/year) (4.4%), moderate-PD-volume surgeons with high OM (3.4%), and high-PD-volume surgeons with high OM (2.7%) each had lower mortality than low-PD-volume surgeons with low OM (9.3%; all p ≤ 0.02). The frequency of prolonged hospitalization among low-PD/high-OM surgeons (45.3%) was lower than among low-PD/low-OM surgeons (61.6%; p < 0.001). Increasing OM volume was associated with decreased inpatient mortality, shorter hospital stay, and lower likelihood of any postoperative complication, using unadjusted regression (all p < 0.001). Adjusted regression results indicated that increasing OM volume is a significant predictor of decreased odds of a prolonged hospital stay (odds ratio [OR] 0.81; 95% confidence interval [CI] 0.73-0.90; p < 0.001)., Conclusions: Surgeon PD volume is an important predictor of outcomes after PD. However, surgeon OM volume identifies a subset of lower-PD-volume surgeons with more favorable outcomes.

- Abstract
Rapidly involuting congenital haemangiomas (RICHs) are rare benign vascular tumours of infancy. They are generally asymptomatic, but can present with thrombocytopaenia and coagulopathy. Significant complications including life-threatening bleeding, high-output heart failure and liver failure, though rare, can occur. RICHs generally regress by 12-14 months of age and can be managed clinically with symptomatic treatment, watchful waiting and close monitoring of the size of the haemangioma. Medical management (corticosteroids, propranolol) has not shown to be effective, in contrast to infantile haemangioma which will not regress spontaneously and has been noted to respond to medical therapy. Awareness of this diagnosis is important to prevent unnecessary medical and surgical intervention. Here, we present a case of a full-term infant with RICH who presented with thrombocytopaenia and abnormal coagulation profile. The coagulopathy was treated symptomatically, while the lesion was observed with serial ultrasounds and gradually decreased in size., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

- Abstract
Background: Designing effective public health campaigns in areas of armed conflict requires a nuanced understanding of how violence impacts the epidemiology of the disease in question., Methods: We examine the geographical relationship between violence (represented by the location of detonated Improvised Explosive Devices) and polio incidence by generating maps of IEDs and polio incidence during 2010, and by comparing the mean number of IED detonations in polio high-risk districts with non polio high-risk districts during 2004-2009., Results: We demonstrate a geographic relationship between IED violence and incident polio. Districts that have high-risk for polio have highly statistically significantly greater mean numbers of IEDs than non polio high-risk districts (p-values 0.0010-0.0404)., Conclusions: The geographic relationship between armed conflict and polio incidence provides valuable insights as to how to plan a vaccination campaign in violent contexts, and allows us to anticipate incident polio in the regions of armed conflict. Such information permits vaccination planners to engage interested armed combatants to co-develop strategies to mitigate the effects of violence on polio.

- Abstract
Background: Although it is widely acknowledged that areas of conflict are associated with a high health burden, from a geospatial perspective it is difficult to establish these patterns at fine scales because of a lack of data. The release of the "WikiLeaks" Afghan War Diary (AWD) provides an interesting opportunity to advance analysis and theory into this interrelationship., Methods: This paper will apply two different space time analyses to identify patterns of improvised explosive devices (IED) detonations for the period of 2004 to 2009 in Afghanistan., Results: There is considerable spatial and temporal heterogeneity in IED explosions, with concentrations often following transportation links. The results are framed in terms of a resource for subsequent analyses to other existing health research in Afghanistan. To facilitate this, in our discussion we present a Google Earth file of overlapping rates that can be distributed to any researcher interested in combining his/her fine scale health data with a similarly granular layer of violence., Conclusion: The release of the AWD presents a previously unavailable opportunity to consider how spatially detailed data about violence can be incorporated into understanding, and predicting, health related spillover effects. The AWD can enrich previous research conducted on Afghanistan, and provide a justification for future "official" data sharing at appropriately fine scales.
