Abstract
The assessment of depression in people with severe to profound intellectual disability (severe-profound ID) is challenging, primarily due to inability to report internal states such as mood, feelings of worthlessness and suicidal ideation. This group also commonly presents with challenging behaviours (e.g. aggression and self-injury) with debate about whether these behaviours should be considered 'depressive equivalents' or are sensitive for, but not specific to, depression in severe-profound ID. We conducted a systematic review exploring behaviours associated with depression and low mood in individuals with severe-profound ID. The review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (2009) guidelines. Three electronic databases were searched (Embase, PsycINFO and Ovid MEDLINE), and 13 studies were included and rated for quality. Few studies were rated as having high methodological quality. Behaviours captured by standard diagnostic schemes for depression (e.g. Diagnostic and Statistical Manual of Mental Disorders and International Classification of Diseases) showed a relationship with depression in severe-profound ID, including the two core symptoms (depressed affect and anhedonia), as well as irritability, sleep disturbance, psychomotor agitation, reduced appetite and fatigue. Challenging behaviours such as aggression, self-injury, temper tantrums, screaming and disruptive behaviour were associated with depression. Challenging behaviours show a robust relationship with depression. Whilst these behaviours may suggest an underlying depression, study limitations warrant caution in labelling them as 'depressive equivalents'. These limitations include not controlling for potential confounds (autism, other affective disorders and pain) and bias associated with comparing depressed/non-depressed groups on the same behavioural criteria used to initially diagnose and separate these groups. Future studies that use depressive measures designed for ID populations, which control for confounds and which explore low mood irrespective of psychiatric diagnosis, are warranted to better delineate the behaviours associated with depression in this population (PROSPERO 2018: CRD42018103244).

Abstract
Multiple myeloma (MM) is characterised by destructive lytic bone disease, caused by induction of bone resorption and impaired bone formation. Our understanding of the molecular mechanisms responsible for osteoblast suppression, are limited. Using the 5T2MM murine model of MM we have previously shown that suppression of the activity of a known inhibitor of bone formation Dikkopf-1 (Dkk1) prevents the development of lytic bone disease. Here we have demonstrated that another potential inhibitor of bone formation, sclerostin domain containing 1 (Sostdc1) is expressed at low levels in MM and osteoblast lineage cells when these cells are grown separately in cell culture but its expression is significantly induced in both cell types when these cells are in contact. The distribution of Sostdc1 staining in bones infiltrated with 5TGM1 myeloma cells in vivo suggested its presence in both myeloma and osteoblast lineage populations when in close proximity. We have also shown that recombinant Sostdc1 inhibits both bone morphogenic proteins (BMP2 and 7) and Wnt signalling in primary osteoblasts and suppresses differentiation of these cells. Together, these findings suggest that Sostdc1 expression in 5TGM1-infiltrated bones as a result of the interaction between myeloma and osteoblast lineage populations, could result in suppression of osteoblast differentiation.

Abstract
OBJECTIVE To evaluate the relationship of telomere length to the prevalence and incidence of hand osteoarthritis in a longitudinal cohort. DESIGN We conducted a cross-sectional and longitudinal analysis of data from a subset of participants in the Osteoarthritis Initiative (OAI) recruited between February 2004 and May 2006. 274 individuals were eligible for the study based on availability of both baseline and 48-month hand radiographs and peripheral blood leucocyte telomere length data. Mean telomere length of peripheral blood leukocytes (PBL)s from the DNA samples was determined using a validated quantitative polymerase chain reaction (PCR)-based assay, and hand radiographs were analyzed and graded using the Kellgren-Lawrence scale. RESULTS In joint -level analyses, prevalent Interphalangeal Joint Osteoarthritis (IPJOA) was significantly associated with PBL telomere length in the baseline sample in unadjusted analyses (RR = 2.84; 95% CI:0.87-9.29) or in models adjusted for age, sex, and body mass index (aRR = 1.10; 95% CI: 0.96-1.27). The association in crude and adjusted analyses appeared slightly stronger with incident IPJOA, especially in the subset with normal hands at baseline (aRR = 1.62; 95% CI: 1.02-2.57). PBL telomere length was also associated with prevalent HOA at baseline (significant in unadjusted analysis: RR = 1.22; 95% CI 1.06-1.42), but not after adjusting for covariates: aRR = 1.12; 95% CI: 0.96-1.30). The magnitude of association was stronger for incident HOA, especially incident symptomatic HOA (aRR = 1.53; 95% CI: 1.09-2.15). CONCLUSIONS In summary, the results of this exploratory analysis are confirmatory of previous work showing a cross-sectional relationship between telomere length and HOA and add to the field by demonstrating an even stronger association with incident IPJOA, both radiographic and symptomatic.

Abstract
OBJECTIVES Breast screening clients recalled to an assessment clinic experience high levels of anxiety. The culture of the assessment clinic may impact upon client experience, which may influence their future re-engagement in screening. This study aimed to explore the culture of staff-client interactions within a breast cancer assessment clinic. MATERIALS AND METHODS Following an ethnographic approach, twenty-three client journeys were observed, followed by semi-structured interviews with the clients. The observation and interview data were analysed to produce research themes, which were then explored within two focus groups to add a practitioner perspective. RESULTS Multiple staff-client interaction events were observed over a period of several weeks. Client interview feedback was overwhelmingly positive. Three recurrent and sequential themes emerged: breaking down barriers, preparing the ground and sign-posting. These themes outline the changing focus of staff-client interactions during the client's clinic journey, encompassing how anxieties were expressed by clients, and responded to by practitioners. CONCLUSION This study was the first to explore in depth the staff-client interaction culture within a breast assessment clinic using an ethnographic approach. A new perspective on professional values and behaviours has been demonstrated via a model of staff-client interaction. The model documents the process of guiding the client from initial confusion and distress to an enhanced clarity of understanding. A recommendation most likely to have a positive impact on the client experience is the introduction of a client navigator role to guide the clients through what is often a lengthy, stressful and confusing process.

Abstract
BACKGROUND Dystroglycan is a ubiquitously expressed cell adhesion molecule frequently found to be altered or reduced in adenocarcinomas, however the mechanisms or consequences of dystroglycan loss have not been studied extensively. METHODS We examined the consequence of overexpression or RNAi depletion of dystroglycan on properties of in vitro growth migration and invasion of LNCaP, PC3, and DU145 prostate cancer cell lines. RESULTS Using LNCaP cells we observed cell density-dependent changes in β-dystroglycan with the appearance of several lower molecular weight species ranging in size from 43 to 26 kDa. The bands of 31 and 26 kDa were attributed to proteolysis, whereas bands between 43 and 38 kDa were a consequence of mis-glycosylation. The localization of β-dystroglycan in LNCaP colonies in culture also varied, cells with a mesenchymal appearance at the periphery of the colony had more pronounced membrane localization of dystroglycan. Whereas some cells demonstrated nuclear dystroglycan. Increased dystroglycan levels were inhibitory to growth in soft agar but promoted Matrigel invasion, whereas reduced dystroglycan levels promoted growth in soft agar but inhibited invasion. Similar results were also obtained for PC3 and DU145 cells. CONCLUSIONS This study suggests that changes in β-dystroglycan distribution within the cell and/or the loss of dystroglycan during tumorigenesis, through a combination of proteolysis and altered glycosylation, leads to an increased ability to grow in an anchorage independent manner, however dystroglycan may need to be re-expressed for cell invasion and metastasis to occur.

Abstract
BACKGROUND This study compares two diaphyseal osteotomies (scarf and Ludloff) which correct moderate to severe metatarsus primus varus. This is a single surgeon, prospective cohort study with clinical and radiological follow~up at 12 months. MATERIALS AND METHODS There were 57 patients in each group. Both groups were similar in terms of age, gender and preoperative deformity. Clinical assessment included visual analogue scale questionnaires for subjective assessment and functional activities and the American Orthopaedic Foot and Ankle Society (AOFAS) score. Standardized weight bearing radiographs were analyzed. RESULTS There was no statistically significant difference between the two groups at 6 and 12 months in subjective satisfaction, AOFAS score, improvement in functional activities and range of movements. The improvement in pain (at best) and transfer lesions at 12 months was significantly better in the scarf group (p < 0.05). The radiological results at 6 and 12 months including intermetatrsal angle (p < 0.001), hallux valgus angle (p < 0.01), distal metatarsal articular angle and seasmoid position (p < 0.05) were significantly better in the scarf osteotomy group. There were three cases (5%) of delayed union in the Ludloff group. Two of these healed with dorsiflexion malunion. One patient in the Ludloff osteotomy group developed a complex regional pain syndrome. There were two wound complications in the scarf group. CONCLUSION Overall the patients who had a scarf osteotomy had a superior outcome at 6 and 12 months.

Abstract
AIMS Dystroglycan is an important structural and signalling protein that is expressed in most human cells. alpha-Dystroglycan has been investigated and found to be reduced in human cancers, but there is only one published study on the expression of beta-dystroglycan in human cancer and that was only on small numbers of breast and prostatic cancers. The aim was to conduct a comprehensive immunohistochemical survey of the expression of beta-dystroglycan in normal human tissues and common cancers. METHODS AND RESULTS Triplicate tissue microarrays of 681 samples of normal human tissues and common cancers were stained using an antibody directed against the cytoplasmic component of beta-dystroglycan. beta-Dystroglycan was strongly expressed at the intercellular junctions and basement membranes of all normal human epithelia. Expression of beta-dystroglycan was absent or markedly reduced in 100% of oesophageal adenocarcinomas, 97% of colonic cancers, 100% of transitional cell carcinomas of the urothelium and 94% of breast cancers. In the breast cancers, the only tumours that showed any retention of beta-dystroglycan expression were small low-grade oestrogen receptor-positive tumours. The only cancers that showed retention of beta-dystroglycan expression were cutaneous basal cell carcinomas. CONCLUSIONS There is loss or marked reduction of beta-dystroglycan expression (by immunohistochemistry) in the vast majority of human cancers surveyed. Since beta-dystroglycan is postulated to have a tumour suppressor effect, this loss may have important functional significance.

Abstract
BACKGROUND Lactation-induced blindness is a rare but devastating puerperal complication. There are few reported cases and no consistent associated disease processes historically identified. This case illustrates lactation-associated optic neuritis as an early identifier of multiple sclerosis. CASE A nulliparous woman underwent a term vaginal delivery complicated only by chorioamnionitis. She was treated with intravenous antibiotics, which included spontaneous bacterial endocarditis prophylaxis. Her postpartum course was uncomplicated, and she was discharged on postpartum day 2 with her infant. She was readmitted on postpartum day 16 completely blind. Evaluation revealed bilateral optic neuritis. Symptoms were initiated and exacerbated during nursing. Transitory waxing and waning of her visual deficits were noted after aggressive steroid therapy and discontinuing nursing. The patient was subsequently diagnosed with multiple sclerosis of relapsing-remitting type. CONCLUSION Multiple sclerosis must be considered as an etiology for acute puerperal lactation-associated blindness when there is no clear anatomic or infectious cause.

Abstract
The biomechanics of ring avulsion injuries was studied in a cadaveric simulation model. Custom-fitted metal rings attached to a rigid frame were placed over the proximal phalanx of fresh or thawed fresh-frozen specimens. Ring avulsion injuries in 44 fingers were produced with a standardized force applied to the proximal ulna. The progress of injury was evaluated with simultaneous high-speed cinematography and continuous force measurements. The injured digits were x-rayed and categorized according to Urbaniak's classification. Continuous force measurements produced similar curves for all classes of injuries. The average maximum force resulting in class I injuries was 80 N. The average maximum force producing amputation in class III injuries was 154 N, a force much lower than expected. Force measurements for class II injuries were nearly identical to those of class III. This surprisingly minimal force resulting in digit amputation was explained by high-speed cinematography, which showed that the rings tilt on the digits concentrating disruption forces as a result of ring angulation on the finger. Incomplete amputations were due to loss of ring purchase by skin flap eversion. Finally, comparison of high-speed cinematography with force curves suggests that skin rupture rather than skeletal or tendon disruption accounted for the maximum force during ring avulsion injury.

Abstract
OBJECTIVE To examine associations between sociodemographic and psychological characteristics of smokers and delivery of 5 types of smoking cessation counseling interventions by physicians and office staff. METHODS We used a telephone survey of a population-based sample of adult cigarette smokers (N = 3037) who saw a physician in the last year. Primary outcomes included patients' report of whether a physician or other health care provider (1) talked about smoking, (2) advised them to quit, (3) offered help to quit, (4) arranged a follow-up contact, and (5) prescribed nicotine gum or other medication. RESULTS Fifty-one percent of smokers were talked to about their smoking; 45.5% were advised to quit; 14.9% were offered help; 3% had a follow-up appointment arranged; and 8.5% were prescribed medication. In multivariate analyses, the most consistent predictors of receipt of almost all counseling behaviors were medical setting (private physician's office only > care in other settings), health status (fair or poor > good, very good, or excellent), more years of education, greater number of cigarettes smoked per day, stage of readiness to quit smoking (preparation > precontemplation), and greater reported benefits of smoking. CONCLUSIONS Physicians and other health care providers are not meeting the standards of smoking intervention outlined by the National Cancer Institute and the Agency for Health Care Policy and Research. Health care providers who intervene only with those patients who are ready to quit smoking are missing opportunities to provide effective smoking interventions to the majority of their patients. Interventions are also less likely to be provided to healthier and lighter smokers.

Abstract
OBJECTIVE To determine some of the factors influencing the time to progression of cytomegalovirus (CMV) retinitis among HIV-infected patients being treated with foscarnet. DESIGN A retrospective analysis of two open-label Phase I/II studies in multiple university hospitals. Patients were studied in both inpatient and outpatient settings. PATIENTS Of the patients in the databases examined, 31 had adequate pharmacokinetic information and 29 had information on outcome and the other patient covariates. INTERVENTION After induction therapy with foscarnet at a dose of 60 mg/kg three times daily was completed, patients had maintenance therapy with 60-120 mg/kg foscarnet once daily. Doses were subsequently adjusted for changed estimated creatinine clearance. MEASUREMENTS The measured endpoint was time to progression of CMV retinitis. The independent variables examined to determine influence on time to progression included mean peak foscarnet concentration, mean area under the concentration-time curve (AUC) for foscarnet, the positive or negative outcome of a baseline blood culture for CMV, the initial CD4 cell count for a patient and the peak CD4 cell count observed during maintenance therapy. RESULTS A wide range (-10-fold) of foscarnet AUC was observed, even though only a fourfold dose range was employed, and doses were altered for changing estimated creatinine clearance. In a multivariate Cox model, only AUC and the status of the baseline CMV blood culture significantly affected the time to progression of the retinitis. CONCLUSION The AUC produced by a dose of foscarnet has a wide interindividual range. The AUC of foscarnet significantly altered time to progression of the retinitis. However, patients with positive baseline CMV blood cultures had a significantly more shallow dose-response curve. This indicates that the added risk of nephrotoxicity which is present with aggressive foscarnet dosing might be best borne by the subgroup of patients with a positive CMV blood culture at baseline.

Abstract
To determine the applicability of the nonreversed vein graft technique to 1-mm-diameter vessels, 24 New Zealand White rabbits underwent bilateral replacement of 2-cm defects in the femoral artery with vein graft conduits. On one side a standard reversed vein graft (RVG) was employed, and on the other side a nonreversed vein graft (NRVG) was placed after valve disruption with a Hall valvulotome. Patency rates were not statistically different (RVG 87 percent, NRVG 96 percent, p > 0.1). Electron and light microscopy revealed similar endothelial damage and time to endothelial recovery between the two techniques. There was no difference in flow volume between the two techniques. We conclude that the NRVG technique has acceptable patency rates in 1-mm-diameter vessels within the parameters of this study but that further research is required to determine clinical applicability.

Abstract
The plasma lipoprotein (a) [Lp(a)] distribution in caucasians is heavily skewed to the right, with evidence of bimodality. As there is a well-described inverse relationship between apolipoprotein(a) [apo(a)] size and Lp(a) concentration, it is likely that the presence of multiple apo(a) isoforms of differing frequency has a significant impact on the final distribution of Lp(a) concentrations. We have previously described an immunoblot method for examining the relationship between apolipoprotein(a) [apo(a)] size and lipoprotein(a) [Lp(a)] mass among samples heterozygous for apo(a) size, thus eliminating confounding by null or undetected apo(a) isoforms. In the present study, this method has been applied to examine the plasma Lp(a) distribution, independent of the effects of apo(a) isoform size and frequency. Seventy subjects heterozygous for apo(a) size were studied. To take into account the inverse relationship (P < 0.001) between apo(a) isoform size and Lp(a) concentration, Lp(a) data associated with each apo(a) isoform were normalized as multiples of the median Lp(a) concentration for that isoform. These apo(a) isoform-independent Lp(a) data demonstrated a strikingly multimodal distribution, with five major peaks. The relative frequencies of Lp(a) peaks 1-5 were 17.1%, 15.0%, 35.7%, 23.6%, and 8.6%, and associated median Lp(a) concentrations were 1.0, 6.2, 15.0, 21.8, and 39.6 mg/dL, respectively. Multivariate analysis demonstrated that apo(a) isoform size accounted for 23% and isoform-independent Lp(a) peaks for 59.5% of the variation in Lp(a) concentration. Further investigation of the characteristics of the apo(a) isoform-independent Lp(a) distribution is warranted.

Abstract
The aim of the study was to assess the effect of application of OpSite dressings on the pain and quality of life in 33 patients with chronic diabetic neuropathy. The effect of OpSite was compared with no treatment. After a run-in period of 2 weeks, OpSite was applied to one of the painful legs for 4 weeks. This was followed by another period of 4 weeks when OpSite was switched to the opposite leg. Pain was assessed by visual analogue scale and the primary analysis variable was within patient difference in pain between OpSite leg and no treatment leg at week 4 corrected for baseline. Secondary variables were paracetamol pill ingestion and the quality of life dimensions, sleep, mobility, contact discomfort, appetite, and mood. Changes in these variables from baseline to weeks 4 and 8 were analysed. There was a significantly greater reduction in pain in the OpSite treated limbs than the control limbs (p < 0.001). By week 4 paracetamol intake also declined significantly (p = 0.034) and patients experienced a significant improvement in contact discomfort, sleep, mood, appetite, and mobility (p < 0.002 for all 5 variables). OpSite appeared to alleviate the pain associated with diabetic painful neuropathy and thus improved patients' quality of life.

Abstract
Ulceration associated with nonsteroidal anti-inflammatory drug (NSAID) use is a common problem in elderly patients. The postulated cause of NSAID ulceration is multifactorial but is probably related to the inhibition of the cyclo-oxygenase pathway and a subsequent decrease in mucosal prostaglandin levels. Epidermal growth factor (EGF), on the other hand, has been shown to be gastroprotective, stimulating DNA synthesis, and preventing ASA-induced gastric ulceration. Since EGF is important in gastric mucosal protection, we questioned whether the potential ulcerogenic properties of indomethacin were related in part to decreasing salivary EGF. Twenty healthy male volunteers with no gastrointestinal complaints received indomethacin 50 mg P.O. t.i.d. for 3 consecutive days. Saliva and serum were collected before indomethacin treatment and repeated 2 h after the last indomethacin dose. Stimulated salivary samples were collected for 15 min in fasted subjects and assayed for EGF, whereas serum indomethacin levels were determined by high-performance liquid chromatography. EGF levels significantly decreased by 33% after indomethacin (p < 0.03), and this decrement was linearly related to serum indomethacin concentrations (r = 0.58; p < 0.048). Salivary output did not change after indomethacin treatment. Based on this data, we concluded that indomethacin's ulcerogenic properties may be related to its prostaglandin inhibitory properties as well as its ability to decrease salivary EGF output.

Abstract
Soft-tissue infection after lower-extremity trauma has not been studied in detail in light of recent data on the biology of infection. This article examines specific problems in lower-extremity trauma that allow the wound to become susceptible to wound infection. It also illustrates the various principles of wound management in lower-extremity trauma that serve to prevent infection. Two case examples are used to illustrate principles of management. Other wound problems in lower-extremity trauma are also discussed, such as rabies, necrotizing soft-tissue infection, tetanus, and diabetic foot infections.

Abstract
The charts of 106 patients with metastasis from an unknown primary cancer were reviewed to formulate a more appropriate investigative strategy than is presently employed. The spinal column was the most common site for initial presentation of metastatic disease (26.5 percent). The primary tumor was identified before death in 31.3 percent of patients and after death in 6.6 percent. Lung cancer was found in 40 percent of patients with identified primary tumors. Diagnostic studies directed at specific symptoms had a significantly greater yield. Electroencephalograms, gallium scans, thyroid scans, and mammograms were not useful as screening studies. Conversely, bone scans were positive in 46.5 percent of asymptomatic patients and in 88 percent of symptomatic patients. Chest roentgenograms were suggestive of malignant tumors in 43.6 percent of patients. Results of liver scans were predictable on the basis of changes in the alkaline phosphatase level and clinical liver examination. History and physical examination should clearly document the stage of disease, evaluate possible primary sites, and rule out impending acute complications. Chest roentgenograms and bone scans should be obtained early and open biopsy of accessible lesions scheduled promptly. Efforts should be directed at ruling out the more treatable malignant tumors. Further work-up is then indicated only by the development of specific symptomatology. Since median patient survival after initial presentation is only 6.6 months, prolonged hospitalization for numerous nonproductive diagnostic tests seems inappropriate.
