Abstract
Palatal fistulae are a recognised complication in individuals who have undergone surgical repair of a cleft palate, however, congenital or idiopathic palatal fistulae are rare. This report discusses the presentation and treatment of a 16-year-old female with a submucous cleft palate, who presented with a recent onset change in speech and evidence of a new palatal fistula. There was no history of recent infection or known trauma, and the patient had not undergone any previous palatal surgery. This report discusses the clinical presentation, recommended management and relevant literature for this rare phenomenon.

Abstract
Alveolar recruitment manoeuvres (ARM) performed during general anaesthesia improve oxygenation; however cardiovascular depression may be observed. The aim of the study was to compare the effects of sustained inflation (SI) and stepwise ARMs on cardiac output (CO), mean arterial blood pressure and arterial oxygen tension (PaO2) in ten mechanically ventilated goats anaesthetised with isoflurane. In the SI ARM, peak inspiratory presure (PIP) was increased to 30 cmH2O and sustained for 20 s. In the stepwise ARM, the PIP was increased by 5 cmH2O each minute for three minutes from 10 to 25 cmH2O. Both ARMs were followed by positive end-expiratory pressure of 5 cmH2O. Paired lithium dilution CO measurements and arterial blood samples were obtained before and after each ARM. The order of the ARM was randomised and each goat was subjected to both techniques. Data was reported as median and interquartile range (IQR). Significance was set at 0.05. The median change in CO (measured by subtracting values after and before ARM) was -0.15 L min-1 (IQR -0.51; 0.03) and - 0.90 L min-1 (IQR -1.69; -0.58) for SI and stepwise ARM respectively (p = 0.04). The median change in PaO2 was 3 kPa (IQR -2.7; 7.6) and 0.4 kPa (IQR -3.4; 5.5) for SI and stepwise ARM respectively (p = 0.03). In conclusion, SI ARM causes less impact on CO and provides a better improvement in PaO2 compared to stepwise ARM in goats.

Abstract
Introduction: Lipomata are soft-tissue mesenchymal neoplasms that are benign in nature and often asymptomatic. Lipomata commonly occur in the body, however, only 1%–5% are identified within the oral cavity, and lipomata with osseous metaplasia account for <1% of all lipomata. Materials and Methods: A PubMed literature review designating search terms including “oral” and “parosteal lipoma” or “lipoma with osseous metaplasia” or “ossifying lipoma” or “osseous lipoma” was conducted. Results: The literature review identified two previous reports of parosteal localization of lipomata in the mandible and 22 cases of lipomata with osseous metaplasia within the oral cavity. Conclusions: With the initial suspicion of a more malevolent diagnosis, this rare entity, with only two other cases identified, is important to consider in the clinician's differential diagnoses.

Abstract
Background Among people living with HIV (PLWH), physical intimate partner violence (IPV) is associated with poor virologic, psychiatric, and behavioral outcomes. We examined non-physical, psychological intimate partner violence (psy-IPV) and HIV care outcomes using data from two U.S. consortia. Methods We conducted multivariable analyses with robust standard errors to compare patients indicating/not indicating psy-IPV. Results Among PLWH (n = 5950), 9.5% indicated psy-IPV; these individuals were younger (− 3; 95% CI [− 2,-4], p-value < 0.001), less likely to be on antiretroviral treatment (ART) (0.73 [0.55,0.97], p = 0.03), less adherent to ART (− 4.2 [− 5.9,-2.4], p < 0.001), had higher odds of detectable viral load (1.43 [1.15,1.78], p = 0.001) and depression (2.63 [2.18,3.18], p < 0.001), and greater use of methamphetamines/crystal [2.98 (2.30,3.87),p < 0.001], cocaine/crack [1.57 (1.24,1.99),p < 0.001], illicit opioids [1.56 (1.13,2.16),p = 0.007], and marijuana [1.40 (1.15,1.70), p < 0.001]. Conclusion Psychological IPV, even in the absence of physical or sexual IPV, appears to be associated with HIV care outcomes and should be included in IPV measures integrated into routine HIV care.

Abstract
Abstract
Sixteen laboratories participated in an AOAC–American Spice Trade Association (ASTA) collaborative study of a liquid chromatographic (LC) method for determining capsaicinoids in capsicums and their extractives. Capsicums are extracted with ethanol by refluxing and then filtered. Capsaicinoids in the filtrate are separated by re- versed-phase LC and detected spectrophotometri� cally with external standard quantitation. Participants analyzed 6 ground capsicum and 3 oleoresin products as 12 samples from a mixed scheme of blind duplicates and Youden matched pairs. Average repeatability and reproducibility standard deviations (sr and sR, respectively) and average relative standard deviations (RSDr and RSDR, respectively) for ground red pepper were as follows: sr, 610 Scoville heat units (SHU); sR, 1730 SHU; RSDr, 1.7%; RSDR, 4.9%. For ground chili peppers, the values were sr, 60 SHU; sR, 160 SHU; RSDr, 4.0%; RSDR, 10.6%. For oleoresin red pepper, the averages were sr, 46820 SHU; sR, 54990 SHU; RSDr, 8.5%; RSDR, 11.2%. The LC method has been adopted first action by AOAC INTERNATIONAL.

Abstract
OBJECTIVE To describe characteristics, presentation, time to diagnosis and diagnostic findings of patients with intestinal tuberculosis (ITB) in a low-burden country. METHOD Retrospective study of 61 consecutive ITB patients diagnosed between 2008 and 2014 at a large East London hospital. RESULTS Forty of sixty-one patients were male. Mean age was 34.6 years. 93% of patients were born abroad, mostly from TB-endemic areas (Indian subcontinent: 88%, Africa: 9%). 25% had concomitant pulmonary TB. Median time from symptom onset to ITB diagnosis was 13 weeks (IQR 3-26 weeks). Ten patients were initially treated for IBD, although patients had ITB. The main sites of ITB involvement were the ileocaecum (44%) or small bowel (34%). Five patients had isolated perianal disease. Colonoscopy confirmed a diagnosis of ITB in 77% of those performed. 42 of 61 patients had a diagnosis of ITB confirmed on positive histology and/or microbiology. CONCLUSION Diagnosis of ITB is often delayed, which may result in significant morbidity. ITB should be excluded in patients with abdominal complaints who come from TB-endemic areas to establish prompt diagnosis and treatment. Diagnosis is challenging but aided by axial imaging, colonoscopy and tissue biopsy for TB culture and histology.

Abstract
Vitamin D deficiency is common in older people and increases risk of falls, osteoporosis and fracture. This may be reduced with supplements. Recent Scottish guidelines recommend routine use of vitamin D and calcium for all older housebound, sunlight deprived or institutionalised people. Whilst many outpatients will undoubtedly meet these criteria, others who would benefit may not. We have determined the extent of vitamin D deficiency in older outpatients in our geographical area, to clarify further whether those found to be deficient, would receive supplementation under current guidelines Methodology 102 new patient referrals to outpatient clinics and day hospital were questioned over their social circumstances and activity levels, and had serum 25 - Hydroxy Vitamin D (25(OH)D) levels measured in wintertime Results Mean age was 79.6 (SD 7.3), 31.4% were housebound and 51.0% exposed their skin to sunlight. 72.6% had insufficient vitamin D levels [25(OH)D <50 nmol/l], 27.5% of whom levels were frankly deficient [25(OH)D <25 nmol/l]. Deficiency was significantly more common in females (p=0.002), those attending the falls clinic or day hospital (p=0.021), the housebound (p=0.012) or patients who never exposed their skin to sunlight (p=0.007). However, even in those patients who were outdoors frequently or who did expose their skin to the sun, the mean vitamin D levels remained insufficient [mean 25(OH)D = 45.6 (SD 26.2) nmol/l and 47.9 (SD 26.3) nmol/l respectively]. Conclusions The prevalence of vitamin D deficiency is high in older outpatients in this geographical area. These patients may benefit from routine vitamin D and calcium, but currently many would not be targeted in recent Scottish Executive recommendations because they are not housebound and sunlight deprived.

Abstract
his qualitative study follows previous research on how meticillin-resistant Staphylococcus aureus (MRSA) affects patients as reported by healthcare workers. The aim of this study was to research the phenomenon of being colonised with MRSA from the patient's perspective. A total of 14 patients were interviewed following discharge from hospital, transcripts were then analysed using an interpretive phenomenological approach. The key findings are reported under the four themes of information provision, patient understanding, lived experience and information needs. Poor information provision was a key theme, experienced by many patients. This resulted in some patients feeling confused and often anxious, and for some affected their lives both in and out of hospital. Providing good quality and reassuring information appropriate to the patient and their current condition is key to improving understanding, deflecting the impact of the media and reducing significance of this symptom-free state. Recommendations for practice include enhanced training for healthcare workers on how to address sensitively the patient's information needs and reduce unnecessary confusion and distress.

Abstract
BACKGROUND Opioid dependence is associated with high levels of morbidity, yet sparse data exists regarding the health-related quality of life (HRQoL) of individuals with opioid dependence, particularly following treatment initiation. To inform cost-effectiveness analyses of treatment modalities, this study investigates short-term changes in HRQoL following enrollment into opioid agonist treatment (OAT), across treatment modalities and patient subgroups. METHODS Data was analyzed from the Starting Treatment with Agonist Replacement Therapies (START) and Prescription Opioid Addiction Treatment Studies (POATS) randomized controlled trials. Participants included individuals dependent on prescription opioids (POs) or heroin, receiving limited-term or time-unlimited treatment. PO- or heroin-users in START received buprenorphine/naloxone (BUP/NX) or methadone (MET) over 24 weeks. PO-users in POATS received psychosocial care and short-term (4-week) taper with BUP/NX, with non-responders offered subsequent extended (12-week) stabilization and taper. HRQoL was assessed using the short-form SF-6D while in and out of OAT, with distinction between MMT and BUP/NX in START. Linear mixed effects regression models were fitted to determine the independent effects of OAT on HRQoL and characterize HRQoL trajectories. RESULTS Treatment had a similar immediate and modest positive association with HRQoL in each patient subgroup. The association of OAT on HRQoL was statistically significant in each model, with effect sizes between 0.039 (heroin-users receiving BUP/NX) and 0.071 (PO-users receiving MET). After initial improvement, HRQoL decreased slightly, or increased at a diminished rate. CONCLUSIONS OAT, whether delivered in time-limited or unlimited form, using BUP/NX or MET, is associated with modest immediate HRQoL improvements, with diminishing benefits thereafter.

Abstract
AIM Recovery is essential to effective performance in climbing competitions which often involve repeated bouts, and sport climbing where climbers may work a route over a number of days prior to a complete ascent. METHODS This study employed a cross-over design to compare water with chocolate milk as recovery aids following an exhaustive bout of high intensity endurance climbing. Ten male climbers (age: 22±1 years; height: 178.5±7.9 cm; mass: 74.7±11.3 kg) climbed a Tredwall (Brewer Ledge M6) until volitional exhaustion. The participants consumed either water or chocolate milk 20 minutes after the climb and then again with their evening meal. The exercise protocol was repeated 24 hours after the original climb. The second condition was completed 7 days later. Workload indicators of heart rate, rate of perceived exertion (RPE), blood lactate and muscle soreness scores were recorded alongside climbing performance measures of duration and distance of the climb. A improved performance was found after the consumption of chocolate milk, with both a greater distance climbed (F(1,9)=11.704, P=0.008) and duration (F(1,9) =10.922, P=0.009), there were no differences in end of climb heart rate or RPE. RESULTS Muscle soreness scores were lower three days after exercise following chocolate milk (t(8)=3.773, P=0.005). Chocolate milk as a recovery drink resulted in further sustained climbing, a decrease in muscle soreness, compared to water. It may be pertinent for climbers to consider its use as a recovery aid during repeated climbing bouts. Chocolate milk is a relatively unexplored recovery aid and warrants further attention.

Abstract
OBJECTIVE To compare effects of two passive warming methods combined with a resistive heating mat on perioperative hypothermia in dogs. MATERIALS AND METHODS Fifty-two dogs were enrolled and randomly allocated to receive a reflective blanket (Blizzard Blanket) or a fabric blanket (VetBed). In addition, in the operating room all dogs were placed onto a table with a resistive heating mat covered with a fabric blanket. Rectal temperature measurements were taken at defined points. Statistical analysis was performed comparing all Blizzard Blanket-treated to all VetBed-treated dogs, and VetBed versus Blizzard Blanket dogs within spay and castrate groups, spay versus castrate groups and within groups less than 10 kg or more than 10 kg bodyweight. RESULTS Data from 39 dogs were used for analysis. All dogs showed a reduction in perioperative rectal temperature. There were no detected statistical differences between treatments or between the different groups. CLINICAL SIGNIFICANCE This study supports previous data on prevalence of hypothermia during surgery. The combination of active and passive warming methods used in this study prevented the development of severe hypothermia, but there were no differences between treatment groups.

Abstract
The majority of adolescents initiate sexual activity during their teenage years, making contraception an important aspect of routine adolescent health care. Despite common misperceptions, all available methods of reversible contraception are appropriate for adolescent use. Contraceptive side effects profiles and barriers to use of certain methods should be considered when providing contraceptives to adolescents. In particular, ease of use, confidentiality, and menstrual effects are main concerns of adolescents. Contraceptive counseling with adolescents should describe method efficacy, discuss user preferences, explore barriers to use, counsel regarding sexually transmitted infection prevention, and consider what to do if contraception fails. Emergency contraception should be widely discussed with adolescents, as it is appropriate for use during gaps in other contraceptive use, method failure, and adolescents who are not using another form of contraception. Dual method use (condom plus a highly effective method of contraception) is the gold standard for prevention of both pregnancy and sexually transmitted infections.

Abstract
INTRODUCTION Cancer survivorship is a chronic disease that places patients in limbo between oncologists and primary care clinicians. Strategies have been proposed to ease the shift in coordination of care, including broad-based educational outreach to primary care providers. METHODS Guided by the theory of planned behavior (TPB), predictors of intention to provide survivorship care, including credentials, experience, perception of barriers, and personal survivorship status, were evaluated using logistic regression with a cohort of physicians, nurse practitioners, and registered nurses participating in an unprecedented online continuing medical education/continuing education survivorship care course. RESULTS Results showed that physicians were significantly less likely to express intent to provide survivorship care (odds ratio [OR] = .237, p = .0001) compared to the other groups. Overall, clinicians with 6-10 years of experience were 3 times more likely to express intent to provide survivorship care (OR = 2.86, p = .045) than those with less or more experience. When clinicians perceived the presence of a barrier, they were nearly twice as likely to have diminished intent (OR = 1.89, p = .035). Most participants (66%; n = 1185) selected two barriers: lack of survivorship care plans and treatment summaries (45.4%; n = 821) and lack of education (20.1%; n = 364). DISCUSSION Barriers to the delivery of survivorship care can influence clinicians' intention to provide survivorship care, which varied by years of experience in this study. Interdisciplinary educational strategies featuring midcareer provider champions who have successfully incorporated survivorship care and can offer specific solutions to these barriers are recommended for future interventions.

Abstract
Abstract
Homologous recombination (HR) repair defects are of potential therapeutic relevance in a variety of different cancers. Numerous studies have investigated the rate of BRCA1/2 mutations in triple negative breast cancer, and current clinical studies are investigating the efficacy of agents targeting HR deficiency in this breast cancer subtype. A more comprehensive assay for HR defects might expand the number of patients likely to benefit from these therapies, and may expand their utility to other breast cancer subtypes.
Recently three DNA-based measures of HR deficiency (HRD) have been developed based on whole genome tumor LOH profiles, telomeric allelic imbalance, or large-scale state transitions. These will be referred herein as HRD-LOH, HRD-TAI and HRD-LST respectively. All 3 scores are highly correlated with defects in BRCA1/2 and other pathway genes in breast or ovarian cancer, and are associated with sensitivity to platinum agents.
213 invasive breast tumor samples and matched normal tissue blocks were obtained from 3 commercial vendors. The samples were selected to contain approximately equal numbers of all subtypes of breast cancer as defined by IHC analysis of ER, PR, and HER2. BRCA1/2 mutation screening and BRCA1 promoter methylation analysis was performed, and genome wide SNP profiles were generated. These data were used to calculate HRD-LOH, HRD-TAI, and HRD-LST scores.
Somatic and germline BRCA1/2 mutations were detected in all subtypes of breast cancer at significant levels with the total mutation frequency ranging from 7.8 – 16.4% depending on subtype. In contrast BRCA1 promoter methylation was confined almost exclusively to triple negative tumors (19.7%). Overall BRCA1/2 deficiency ranged from approximately 10% in ER+/Her2- tumors up to approximately 36% in triple negative tumors.
HRD-LOH, HRD-TAI, and HRD- LST scores have previously been shown to be highly significantly associated with BRCA1/2 status in both breast and ovarian cancer. In this dataset all 3 scores showed significant association with BRCA1/2 status for the entire dataset, in addition significant association was observed between the scores and BRCA1/2 status in each of the individual tumor subtypes. The 3 scores were found to be highly correlated with one another, but all 3 were still significant in multivariate analysis. This dataset is not of sufficient size to determine which of these scores is best able to identify BRCA1/2 deficient tumors. It is likely that a combination of the 3 scores will prove to be the most robust predictor of HR deficiency.
This study has demonstrated significant levels of BRCA1/2 deficiency across all subtypes of breast cancer. All 3 HR deficiency assays showed significant association with BRCA1/2 deficiency regardless of breast cancer subtype. The 3 scores are highly correlated, but also additive and a combination of all 3 is likely to provide the best predictor of HR deficiency.

Abstract
A bespoke capillary sample holder is described that attaches to the cold head of a commercially manufactured (PheniX) closed-cycle helium cryostat originally intended for flat-plate geometry. The new holder allows high-resolution synchrotron powder diffraction data to be collected from samples in Debye–Scherrer geometry over the temperature range 11–295 K. To demonstrate that high-quality powder data can be obtained using this new sample holder, structural refinement (Rietveld) and thermal expansion results measured from reference samples (Si and Al) are presented.
