Factors Associated with Attention Deficit Hyperactivity Disorder Medication Use in Community Care Settings.

OBJECTIVES: To examine patient- and provider-level factors associated with receiving attention-deficit/hyperactivity disorder (ADHD) medication treatment in a community care setting. We hypothesized that the likelihood of ADHD medication receipt would be lower in groups with specific patient sociodemographic (eg, female sex, race other than white) and clinical (eg, comorbid conditions) characteristics as well as physician characteristics (eg, older age, more years since completing training). STUDY DESIGN: A retrospective cohort study was conducted with 577 children (mean age, 7.8 years; 70% male) presenting for ADHD to 50 community-based practices. The bivariate relationship between each patient- and physician-level predictor and whether the child was prescribed ADHD medication was assessed. A multivariable model predicting ADHD medication prescription was conducted using predictors with significant (P < .05) bivariate associations. RESULTS: Sixty-nine percent of children were prescribed ADHD medication in the year after initial presentation for ADHD-related concerns. Eleven of 31 predictors demonstrated a significant (P < .05) bivariate relationship with medication prescription. In the multivariable model, being male (OR, 1.34; 95% CI, 1.01-1.78; P = .02), living in a neighborhood with higher medical expenditures (OR, 1.11 for every $100 increase; 95% CI, 1.03-1.21; P = .005), and higher scores on parent inattention ratings (OR, 1.06; 95% CI, 1.03-1.10; P < .0001) increased the likelihood of ADHD medication prescription. CONCLUSIONS: We found that some children, based on sociodemographic and clinical characteristics, are less likely to receive an ADHD medication prescription. An important next step will be to examine the source and reasons for these disparities in an effort to develop strategies for minimizing treatment barriers.

Are Histological Examinations of Arthroplasty Specimens Performed Consistently Across the Country? A Large Database Study.

BACKGROUND: It is currently unknown to what extent routine histological examination of joint arthroplasty specimens occurs across hospitals nationwide. Although this practice is neither supported nor refuted by the available evidence, given the increasing demand for joint arthroplasties, it is crucial to study overall utilization as well as its main drivers. QUESTIONS/PURPOSES: Using national data on joint replacements, we aimed to evaluate: (1) What is the current use of routine histological examination of joint arthroplasty specimens? (2) Does the use vary by geographic location and hospital characteristics? (3) Has use changed over time? METHODS: From the Premier Healthcare database (2006-2016) we included claims data from 87,667 shoulder (595 hospitals, median age 70 years, 16% nonwhite), 564,577 hip (629 hospitals, median age 65 years, 21% nonwhite), and 1,131,323 (630 hospitals, median age 66 years, 24% nonwhite) knee arthroplasties (all elective). Our study group has extensive experience with this data set, which contains information on 20% to 25% of all US hospitalizations. Included hospitals are mainly concentrated in the South (approximately 40%) with equal distributions among the Northeast, West, and Midwest (approximately 20% each). Moreover, the Premier data set has detailed billing information, which allows for evaluations of real-world clinical practice. There was no missing information on the main variables of interest for this specific study. We assessed frequency of histology examination (defined by Current Procedural Terminology codes) overall as well as by hospital characteristics (urban/rural, bed size, teaching status, arthroplasty volume), geographic region (Northeast, South, Midwest, West), and year. Given the large sample size, instead of p values, standardized differences were applied in assessing group differences where a standardized difference of > 0.1 (or 10%) was assumed to represent a meaningful difference between groups. For significance of trends, p values were applied. Percentages provided represent proportions of individual procedures. RESULTS: In most hospitals, histology testing was either rare (1%-10%, used in 187 of 595, 189 of 629, and 254 of 630 hospitals) or ubiquitous (91%-100%, used in 121 of 595, 220 of 629, and 195 of 630 hospitals) for shoulder, hip, and knee arthroplasties, respectively. Overall, histology testing occurred more often in smaller hospitals (37%-53% compared with 26%-45% in larger hospitals) and those located in the Northeast (59%-68% compared with 22%-44% in other regions) and urban areas (32%-49% compared with 20%-31% in rural areas), all with standardized differences > 10%. Histologic examination is slowly decreasing over time: from 2006 to 2016, it decreased from 34% to 30% for shoulder arthroplasty, from 50% to 45% for THAs, and from 43% to 38% for TKAs (all p < 0.001). CONCLUSIONS: Although overall use is decreasing, a substantial number of hospitals still routinely perform histology testing of arthroplasty specimens. Moreover, variation between regions and hospital types suggests that this practice is driven by a variety of factors. This is the first study addressing national utilization, which will be helpful for individual hospitals to assess how they compare with national utilization patterns. Moreover, the findings have clear implications for followup studies, which may be necessary given the exponentially growing demand for arthroplasties. LEVEL OF EVIDENCE: Level III, therapeutic study.

What are the prevalence and risk factors for repeat ipsilateral knee arthroscopy?

PURPOSE: The number of arthroscopic knee surgeries performed annually has increased over the last decade. It remains unclear what proportion of individuals undergoing knee arthroscopy is at risk for subsequent ipsilateral procedures. Better knowledge of risk factors and the incidence of reoperative ipsilateral arthroscopy are important in setting expectations and counselling patients on treatment options. The aim of this study is to determine the incidence of repeat ipsilateral knee arthroscopy, and the risk factors associated with subsequent surgery over long-term follow-up. METHODS: The New York Statewide Planning and Research Cooperative Systems outpatient database was reviewed from 2003 to 2016 to identify patients who underwent elective, primary knee arthroscopy for one of the following diagnosis-related categories of procedures: Group 1: cartilage repair and transfer; Group 2: osteochondritis dissecans (OCD) lesions; Group 3: meniscal repair, debridement, chondroplasty, and synovectomy; Group 4: multiple different procedures. Subjects were followed for 10 years to determine the odds of subsequent ipsilateral knee arthroscopy. Risk factors including the group of arthroscopic surgery, age group, gender, race, insurance type, surgeon volume, and comorbidities were analysed to identify factors predicting subsequent surgery. RESULTS: A total of 765,144 patients who underwent knee arthroscopy between 2003 and 2016, were identified. The majority (751,873) underwent meniscus-related arthroscopy. The proportion of patients undergoing subsequent ipsilateral knee arthroscopy was 2.1% at 1-year, 5.5% at 5 years, and 6.7% at 10 years of follow-up. Among patients who underwent subsequent arthroscopic surgery at 1-, 5-, and 10-year follow-up, there was a greater proportion of patients with worker's compensation insurance (p < 0.001), index operations performed by very high volume surgeons (p < 0.001), and cartilage restoration index procedures (p < 0.001), compared with those who never underwent repeat ipsilateral surgery. CONCLUSION: Understanding the incidence of subsequent knee arthroscopy after index procedure in different age groups and the patterns over 10 years of follow-up is important in counselling patients and setting future expectations. The majority of subsequent surgeries occur within the first 5 years after index surgery, and subjects tend to have higher odds of ipsilateral reoperation for up to 10 years if they have worker's compensation insurance, or if their index surgery was performed by a very high volume surgeon, or was a cartilage restoration procedure. LEVEL OF EVIDENCE: III.

A macrophyte bioassessment approach linking taxon-specific tolerance and abundance in north temperate lakes.

Bioassessment methods are critically needed to evaluate and monitor lake ecological condition. Aquatic macrophytes are good candidate indicators, but few lake bioassessment methods developed in North America use them. The few macrophyte bioassessment methods that do exist suffer from problems related to subjectivity and discernibility along disturbance gradients. We developed and tested a bioassessment approach for 462 north temperate lakes. The approach links macrophyte abundance to lake ecological condition via estimates of taxon-specific abundance-weighted tolerance to anthropogenic disturbance. Using variables related to eutrophication, urban development and agriculture, we calculated abundance-weighted tolerance ranges for 59 macrophyte taxa and clustered them according to their tolerance to anthropogenic disturbance. We also created a composite index of anthropogenic disturbance using 20 variables related to population density, land cover and water chemistry. We used a statistical approach to set ecological condition thresholds based on the observed abundance of sensitive, moderately tolerant and tolerant taxa in each lake. The resulting lake condition categories were usually stable across multiple survey events and largely agreed with condition rankings assigned using expert judgment. We suggest using this macrophyte bioassessment method for federal water quality reports, restoration and management on north temperate lakes.

DUAL-ENERGY X-RAY ABSORPTIOMETRY AND CALCULATED FRAX RISK SCORES MAY UNDERESTIMATE OSTEOPOROTIC FRACTURE RISK IN VITAMIN D-DEFICIENT VETERANS WITH HIV INFECTION.

OBJECTIVE: We evaluated the utility of the World Health Organization (WHO) Fracture Risk Assessment Tool (FRAX) in assessing fracture risk in patients with human immunodeficiency virus (HIV) and vitamin D deficiency. METHODS: This was a retrospective study of HIV-infected patients with co-existing vitamin D deficiency at the Atlanta Veterans Affairs Medical Center. Bone mineral density (BMD) was assessed by dual-energy X-ray absorptiometry (DEXA), and the 10-year fracture risk was calculated by the WHO FRAX algorithm. Two independent radiologists reviewed lateral chest radiographs for the presence of subclinical vertebral fractures. RESULTS: We identified 232 patients with HIV and vitamin D deficiency. Overall, 15.5% of patients met diagnostic criteria for osteoporosis on DEXA, and 58% had low BMD (T-score between -1 and -2.5). The median risk of any major osteoporotic and hip fracture by FRAX score was 1.45 and 0.10%, respectively. Subclinical vertebral fractures were detected in 46.6% of patients. Compared to those without fractures, those with fractures had similar prevalence of osteoporosis (15.3% versus 15.7%; P>.999), low BMD (53.2% versus 59.3%; P = .419), and similar FRAX hip scores (0.10% versus 0.10%; P = .412). While the FRAX major score was lower in the nonfracture group versus fracture group (1.30% versus 1.60%; P = .025), this was not clinically significant. CONCLUSION: We found a high prevalence of subclinical vertebral fractures among vitamin D-deficient HIV patients; however, DEXA and FRAX failed to predict those with fractures. Our results suggest that traditional screening tools for fragility fractures may not be applicable to this high-risk patient population.

Self-reported Barriers to Treatment Engagement: Adolescent Perspectives from the National Comorbidity Survey-Adolescent Supplement (NCS-A).

The objective of this study was to assess youth self-reported treatment barriers in the past 12 months to obtain youth's perspective on reasons they seek treatment, do not engage in treatment, or terminate treatment. The present study uses data from the National Comorbidity Survey-Adolescent Supplement (NCS-A), a nationally representative survey administered to youth ages 13-18 that was conducted between February 1, 2001 and January 30, 2004. A total of 10,123 youth participated in the NCS-A study and provided the information on which the current paper draws its data. Within the past 12 months over 63% of youth reported seeking treatment to manage and cope with emotions. The greatest percentage of youth reported that they did not seek treatment because they wanted to handle the problem on their own (59.3%). The greatest percentage of youth reported that treatment was terminated because they wanted to handle the problem on their own (57.5%). Findings suggest professionals need to educate youth about the importance of professional treatment to increase engagement. If providers can motivate youth to see the value of treatment and help them understand that there can be positive outcomes, they may be less likely to terminate prematurely.

Effect of sitagliptin therapy on triglyceride-rich lipoprotein kinetics in patients with type 2 diabetes.

AIM: To investigate the effects of sitagliptin therapy on the kinetics of triglyceride-rich lipoprotein (TRL) apolipoprotein (apo)B-48, VLDL apoB-100, apoE and apoC-III in patients with type 2 diabetes. METHODS: Twenty-two subjects with type 2 diabetes were recruited in this double-blind crossover study, during which the subjects received sitagliptin (100 mg/day) or placebo for a 6-week period each. At the end of each phase of treatment, the in vivo kinetics of the different apolipoproteins were assessed using a primed-constant infusion of l-[5,5,5-D3]leucine for 12 h, with the participants in a constantly fed state. RESULTS: Sitagliptin therapy significantly reduced fasting plasma triglyceride (-15.4%, p = 0.03), apoB-48 (-16.3%, p = 0.03) and free fatty acid concentrations (-9.5%, p = 0.04), as well as plasma HbA1c (placebo: 7.0% ± 0.8 vs. sitagliptin: 6.6% ± 0.7, p < 0.0001) and plasma glucose levels (-13.5%, p = 0.001), without any significant effect on insulin levels. Kinetic results showed that treatment with sitagliptin significantly reduced the pool size of TRL apoB-48 by -20.8% (p = 0.03), paralleled by a reduction in the production rate of these particles (-16.0%, p = 0.03). The VLDL apoB-100 pool size was also significantly decreased by sitagliptin therapy (-9.3%, p = 0.03), mainly because of a reduction in the hepatic secretion of these lipoproteins, although this difference did not reach statistical significance (-9.2%, p = 0.06). CONCLUSIONS: Treatment with sitagliptin for 6 weeks reduced triglyceride-rich apoB-containing lipoprotein levels by reducing the synthesis of these particles.

Splenic Infarction Due to Epstein-Barr Virus: A Case Report and Literature Review.

Splenic infarction is a rare and likely underdiagnosed complication of Epstein-Barr virus (EBV)-associated infectious mononucleosis (IM). Here, we describe an 18-year-old Guyanese male with persistent severe left-sided abdominal pain found to be EBV positive and have a large splenic infarct, along with a transient decrease in protein C, protein S, and antithrombin III activity levels. He was treated with supportive care and anticoagulated with heparin and apixaban. We review prior reports and perspectives on underlying pathophysiology, diagnosis, and the management of these cases, which likely do not require anticoagulation but may be considered on a per-case basis.

A systematic review examining caregivers' of color experiences with the diagnostic process of autism spectrum disorder.

LAY ABSTRACT: Children of color are diagnosed with autism later than White children. Caregivers of color are also more likely than White caregivers to report that their child's healthcare providers do not treat them as a partner, spend enough time with them, or respect their culture and values. We wanted to better understand the experiences of caregivers of color with the diagnostic process of autism spectrum disorder, from the time they discuss developmental concerns with their child's primary care provider to when the diagnosis is shared with them. We systematically reviewed the literature and found 15 articles that explored the experiences of caregivers of color. Caregivers of color described that they faced large-scale barriers, such as the cost of appointments, transportation, and long wait lists. They also reported negative experiences with providers, including providers not taking their concerns seriously, making assumptions about caregivers, and delaying referrals for an evaluation. Caregivers stated that their own lack of knowledge of autism spectrum disorder, stigma, their family's thoughts and opinions, and cultural differences between providers and caregivers served as barriers during the diagnostic process. Communication challenges were discussed and included use of medical and technical jargon, a lack of follow-up, language barriers, and difficulty obtaining high-quality interpreters. Some families described providers, other individuals, community networks, and self-advocacy as helpful during the diagnostic process. Large-scale changes are needed, such as increases in the number of providers who are trained in diagnosing Autism. Provider-level changes (e.g. implicit bias training) are also important for improving caregivers' experiences.

An inconvenient truth: treatment of displaced paediatric supracondylar humeral fractures.

The need for emergent management of displaced paediatric supracondylar humeral fractures is being questioned in the literature. Open reduction rates of up to 46% have been reported in the non-emergent management of these injuries. At our institution these fractures are managed as operative emergencies by senior personnel. To examine the ongoing need for this policy we reviewed our results. All patients managed over a five year period with Gartland type IIB or III paeditric supracondylar humeral fractures were identified and a comprehensive chart and radiographic review undertaken. The mean time from injury to fracture reduction and stabilization was 6.6 h. Consultants performed or supervised 90% of cases. Open reduction was necessary in 5% of cases. Complications included a perioperative nerve injury rate of 6% and a superficial pin site infection rate of 3%. This study suggests that, despite the challenge to trauma on-call rostering, the emergency management of these injuries is advantageous to patients in units of our size. Based on the data presented here we continue our practice of emergent management. We suggest that units of a similar size to our own would show a benefit from an analogous policy albeit an inconvenient truth.

A Case of Acute Liver Failure in a Patient on Isoniazid Prophylaxis for Latent Tuberculosis.

Isoniazid (INH) is widely used for latent Mycobacterium tuberculosis despite the known risk of liver injury, with severe hepatitis occurring in up to 1% of patients. We report a patient who presented with two weeks of anorexia, nausea, and jaundice following six months of INH monotherapy for latent tuberculosis (TB). After other causes of liver injury were ruled out, she underwent a liver biopsy showing submassive necrosis, hepatocellular dropout, and lobular inflammation with no evidence of fibrosis. She was also found to have acute portal hypertension. She was diagnosed with drug-induced liver injury (DILI) and was treated with n-acetyl cysteine (NAC), ursodiol, and vitamin K. She recovered without the need for a liver transplant. This case supports the need for monitoring of liver tests in high-risk individuals on INH therapy to reduce the risk of hepatotoxicity.

Predictors of Stimulant Medication Continuity in Children with Attention-Deficit/Hyperactivity Disorder.

OBJECTIVE: The objective of this study was to examine the simultaneous impact of patient-related and parent-related factors, medication-related factors, and health care system-related factors on attention-deficit/hyperactivity disorder (ADHD) medication continuity. METHOD: Stimulant-naïve children (N = 144, M age = 8 yrs, 71% male) with ADHD completed a methylphenidate (MPH) trial and were followed for 1 year after trial completion and return to community care. Multivariable analysis investigated predictors of (1) having at least 1 filled ADHD prescription after return to community care versus none and (2) having more days covered with medicine after return to community care. Predictors included race; age; sex; income; baseline ADHD symptom severity; MPH trial experience; child and parent mental health conditions; and parent beliefs about ADHD, ADHD medications, and therapeutic alliance. RESULTS: One hundred twenty-one children (84%) had at least 1 filled ADHD medication prescription (mean = 178 d covered by medication) in the year after return to community care. Multivariable models found that a weaker perceived clinician-family working alliance predicted not filling any ADHD prescriptions. Among those who filled ≥1 prescription, factors linked to fewer days of ADHD medication coverage included child sociodemographic factors (non-White race, older age, being female, and lower income), lower parent beliefs that the child's ADHD affects their lives, and higher parent beliefs that medication is harmful, while child oppositional defiant disorder and parental ADHD predicted having more days of medication coverage. CONCLUSION: Child demographic factors, parent beliefs, and medication-related factors are associated with continuation of ADHD medication. These findings may facilitate the development of effective strategies to improve ADHD medication continuity for children from diverse groups.

Latino-to-Latino: Promotores' Beliefs on Engaging Latino Participants in Autism Research.

BACKGROUND: In Latino(a) communities, promotores de salud (i.e., community health workers; promotores) are becoming critical participants in prevention, health promotion, and the delivery of health care. Although involving culturally diverse participants in research is a national priority, recruitment and retention of research participants from these groups is challenging. Therefore, there is an increased need to identify strategies for successful recruitment of participants from underrepresented minority backgrounds. Our overall study purpose was to gain promotores' perspectives on recruiting Latino(a) immigrant community members for an intervention study on autism spectrum disorders (ASD). The goal of this paper is to explore insider promotores' views on the barriers and facilitators to research participation in the Latino(a) community and learn strategies for recruiting Latino(a) participants in a nontraditional destination city. METHODS: We conducted qualitative focus groups with an established group of promotores known as Latinos Unidos por la Salud (LU-Salud), who were members of a community-academic research team. Fifteen LU-Salud promotores participated in the focus groups. Focus group interviews were analyzed by using Leininger's data analysis enabler. These results will inform our partnerships with promotores and Latino(a) neighborhood agencies to increase recruitment for community-based research on promoting awareness of ASD among Latino(a) families. RESULTS: Promotores were credible community members able to gain community trust and committed to improving the health and well-being of their Latino(a) community, including involving them in research. Latino(a) research involvement meant facilitating community members' engagement to overcome barriers of distrust around legal and health care systems. Challenges included legal uncertainties, language and literacy barriers, health knowledge, and economic hardship. Promotores also voiced the diversity of cultural practices (subcultures) within the Latino(a) culture that influenced: (1) research engagement, (2) guidance from promotores, (3) immersion in the Latino(a) community, and (4) health and well-being. Experienced promotores, who are living in a nontraditional migration area, believe the primary facilitator to increasing research involvement is Latino(a)-to-Latino(a) recruitment. CONCLUSIONS: These findings will aid in building partnerships to recruit participants for future studies that promote early recognition of ASD in the Latino(a) community.

Pathogenesis to management of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is the most common primary liver cancer whose incidence continues to rise in many parts of the world due to a concomitant rise in many associated risk factors, such as alcohol use and obesity. Although early-stage HCC can be potentially curable through liver resection, liver-directed therapies, or transplantation, patients usually present with intermediate to advanced disease, which continues to be associated with a poor prognosis. This is because HCC is a cancer with significant complexities, including substantial clinical, histopathologic, and genomic heterogeneity. However, the scientific community has made a major effort to better characterize HCC in those aspects via utilizing tissue sampling and histological classification, whole genome sequencing, and developing viable animal models. These efforts ultimately aim to develop clinically relevant biomarkers and discover molecular targets for new therapies. For example, until recently, there was only one approved systemic therapy for advanced or metastatic HCC in the form of sorafenib. Through these efforts, several additional targeted therapies have gained approval in the United States, although much progress remains to be desired. This review will focus on the link between characterizing the pathogenesis of HCC with current and future HCC management.

Smooth muscle phenotypic diversity is mediated through alterations in myocardin gene splicing.

Myocardin (MYOCD) is a smooth and cardiac muscle-specific transcriptional coactivator that is required for the proper expression of contraction-related genes. Through its function to transactivate effector genes, MYOCD plays an essential role in mediating the switch between contractile and non-contractile phenotypes, particularly in smooth muscle cells (SMC). There are at least two known transcript variants of MYOCD that are expressed in SMC, differing only by the presence (+) or absence (Δ) of Exon 11. To date, no functional role has been assigned to the domain encoded by Exon 11, nor have any notable differences between the ability of each isoform to activate contraction-related genes been observed. In this study we compared sequences for Exon 11 among several mammalian species and identified a highly conserved, putative target sequence for glycogen synthase kinase 3 (GSK3) phosphorylation, suggesting a regulatory role for Exon 11 that can be modulated by alternative splicing. The function of Exon 11 was investigated by altering MYOCD splice selection in cultured porcine SMC with small interfering RNAs (siRNA) and specific chemical inhibitors, resulting in a relative increase in expression of ΔExon 11 variants in the endogenous pool of MYOCD mRNA. The relative increase in ΔExon 11 mRNAs correlated with a reduction of contractile phenotype in the porcine SMC as evidenced by morphological assessment and molecular analysis of effector genes. Together, these data suggest that MYOCD ΔExon 11 may participate in modulating SMC phenotype, potentially acting as a dominant-negative repressor of contraction-related genes.

Validation of a susceptibility, benefits, and barrier scale for mammography screening among Peruvian women: a cross-sectional study.

BACKGROUND: Perceived beliefs about breast cancer and breast cancer screening are important predictors for mammography utilization. This study adapted and validated the Champion's scale in Peru. This scale measures perceived susceptibility for breast cancer and perceived benefits and barriers for mammography. METHODS: A cross-sectional study was conducted among women ages 40 to 65 attending outpatient gynecology services in a public hospital in Peru. A group of experts developed and pre-tested a Spanish version of the Champion's scale to assess its comprehensibility (N=20). Factor analysis, internal consistency, and test-retest reliability analyses were performed (N=285). Concurrent validity compared scores from participants who had a mammogram and those who did not have it in the previous 15 months. T-test and multiple regression analysis adjusting for socio-demographic factors, mammography knowledge and other preventive behaviors were performed. RESULTS: The construct validity and reliability were optimal. Cronbach-Alpha coefficients were 0.75 (susceptibility), 0.72 (benefits) and 0.86 (barriers). Concurrent validity analysis showed an association between barriers and mammography screening use in bivariate (22.3±6.7 vs. 30.2±7.6; p<0.001) and multiple regression analysis (OR=0.28, 95% CI=0.18-0.43). Ages 50-60 years (OR=2.35, 95% CI=1.19-4.65), history of prior Papanicolaou test (OR=3.69, 95% CI=1.84-7.40), and knowledge about breast cancer and mammography (OR=3.69, 95% CI=1.84-7.40) were also independently associated with mammography screening use. CONCLUSION: Concurrent validity analysis showed that the Champion's scale has important limitations for assessing perceived susceptibility for breast cancer and perceived benefits for mammography among Peruvian women. There is still a need for developing valid and reliable instruments for measuring perceived beliefs about breast cancer and mammography screening among Peruvian women.

Organ specific regenerative markers in peri-organ adipose: kidney.

BACKGROUND: Therapeutically bioactive cell populations are currently understood to promote regenerative outcomes in vivo by leveraging mechanisms of action including secretion of growth factors, site specific engraftment and directed differentiation. Constitutive cellular populations undoubtedly participate in the regenerative process. Adipose tissue represents a source of therapeutically bioactive cell populations. The potential of these cells to participate in various aspects of the regenerative process has been demonstrated broadly. However, organ association of secretory and developmental markers to specific peri-organ adipose depots has not been investigated. To characterize this topographical association, we explored the potential of cells isolated from the stromal vascular fraction (SVF) of kidney sourced adipose to express key renal associated factors. RESULTS: We report that renal adipose tissue is a novel reservoir for EPO expressing cells. Kidney sourced adipose stromal cells demonstrate hypoxia regulated expression of EPO and VEGF transcripts. Using iso-electric focusing, we demonstrate that kidney and non-kidney sourced adipose stromal cells present unique patterns of EPO post-translational modification, consistent with the idea that renal and non-renal sources are functionally distinct adipose depots. In addition, kidney sourced adipose stromal cells specifically express the key renal developmental transcription factor WT1. CONCLUSIONS: Taken together, these data are consistent with the notion that kidney sourced adipose stromal (KiSAS) cells may be primed to recreate a regenerative micro-environment within the kidney. These findings open the possibility of isolating solid-organ associated adipose derived cell populations for therapeutic applications in organ-specific regenerative medicine products.

Prevalence and risk factors for diabetes mellitus among tuberculosis patients in Moshi Municipal Council, Kilimanjaro Tanzania.

BACKGROUND: Diabetes Mellitus (DM) is a worldwide public health problem and its prevalence has been rising rapidly in low and middle income countries (LMICs) including Tanzania. According to WHO report 2015, DM is ranked number six as a leading cause of death worldwide. Strong evidence suggests that DM may be associated with Tuberculosis (TB) and could affect TB treatment outcomes. Tanzania is among the 22 countries that have a high burden of TB and currently facing increased epidemic of DM. The increasing diabetes prevalence may be a threat to TB control and counteract strategies to end TB by 2030 as proposed by WHO. OBJECTIVE: To determine proportion of TB patients who are co-infected with DM in Moshi municipal council, Kilimanjaro Tanzania. METHODOLOGY: This study was a hospital based cross-sectional study conducted in April to July 2018 at 4 health facilities; Mawenzi Regional Referral hospital, St. Joseph District Designated hospital, Pasua Health center and Majengo Health centre in Moshi municipal. The study included adults aged 18 years and above attending either of the 4 health facilities for TB care. The study included newly diagnosed and those who were on TB treatment. Interviews were conducted followed by blood glucose testing. Data was entered and analysed using SPSS. RESULTS: A total of 153 TB patients were enrolled, their mean age was 42.5 (±14.75) years and 46 (30.1%) were females. The prevalence of DM among TB patients in this study was 9.2%. Factors associated with TB-DM comorbidity were: age (OR 4.43, 95% CI: 1.18-16.55), HIV status (OR 3.88, 95% CI: 1.06-14.11), and family history of DM (OR 6.50, 95% CI 0.67-25.56). CONCLUSION: One in ten patients with TB had confirmed DM. There is a need for future studies to assess if DM influences TB treatment and outcomes in this setting.

Ease of oral administration and owner-perceived acceptability of triglyceride oil, dissolving thin film strip, and gelatin capsule formulations to healthy cats.

OBJECTIVE: To compare owner-assessed ease of administration and overall acceptability of 3 chemically inactive formulations administered PO to cats. ANIMALS: 90 healthy client-owned cats. PROCEDURES: Cats were randomly assigned to receive 1 of 3 formulations PO once daily for 14 days: medium chain triglyceride (MCT) oil, dissolving thin film strips (proprietary ingredients), or gelatin capsules filled with microcrystalline cellulose. Owners administered the formulations and rated ease of administration daily on a 10-cm visual analogue scale (VAS). At the end of the study, owners rated overall acceptability of formulations from their own perspective and their overall perception of acceptability to their cat. RESULTS: Mean VAS scores for daily ease of administration of MCT oil and film strips were significantly higher than scores for gelatin capsules at all time points, except on days 2, 4, and 7. There was no difference between MCT oil and film strip formulation scores. Mean VAS scores were 8.8 (MCT oil), 8.9 (film strips), and 7.4 (gelatin capsules) for overall acceptability to owners and 8.0 (MCT oil), 8.3 (film strips), and 6.7 (gelatin capsules) for overall owner-perceived acceptability to cats. CONCLUSIONS AND CLINICAL RELEVANCE: Daily ease of administration on 11 of 14 days and overall owner-perceived acceptability to cats were scored significantly higher for film strips and MCT oil, compared with scores for gelatin capsules. Overall acceptability to owners followed a similar pattern; however, the differences were not significant. Dissolving thin film strip or MCT oil vehicles may allow for easier PO administration of medication to cats than does administration of gelatin capsules.
