Does an Injection of Adipose-Derived Mesenchymal Stem Cells Loaded in Fibrin Glue Influence Rotator Cuff Repair Outcomes? A Clinical and Magnetic Resonance Imaging Study

Background: The mesenchymal stem cell (MSC)–based tissue engineering approach has been developed to improve the treatment of rotator cuff tears. Hypothesis/Purpose: The purpose was to determine the effect of an injection of adipose-derived MSCs loaded in fibrin glue during arthroscopic rotator cuff repair on clinical outcomes and to evaluate its effect on structural integrity using magnetic resonance imaging (MRI). The hypothesis was that the application of adipose-derived MSCs would improve outcomes after the surgical repair of a rotator cuff tear. Study Design: Cohort study; Level of evidence, 3. Methods: Among 182 patients treated with arthroscopic surgery for a rotator cuff tear, 35 patients treated with arthroscopic rotator cuff repair alone (conventional group) were matched with 35 patients who underwent arthroscopic rotator cuff repair with an injection of adipose-derived MSCs loaded in fibrin glue (injection group) based on sex, age, and lesion size. Outcomes were assessed with respect to the visual analog scale (VAS) for pain, range of motion (ROM) (including forward flexion, external rotation at the side, and internal rotation at the back), and functional measures of the Constant score and University of California, Los Angeles (UCLA) shoulder rating scale. Repaired tendon structural integrity was assessed by using MRI at a minimum of 12 months after surgery, and the mean clinical follow-up was 28.8 ± 4.2 months in the conventional group and 28.3 ± 3.8 months in the injection group. Results: The mean VAS score at rest and during motion improved significantly in both groups after surgery. However, there were no significant differences between the groups at the final follow-up (P = .256 and .776, respectively). Compared with preoperative measurements, forward flexion and external rotation at the side significantly improved at the final follow-up in both groups (all P < .05). However, no significant improvements in internal rotation at the back were observed in either group (P = .625 and .834 for the conventional and injection groups, respectively). There were also no significant differences between the groups at the final follow-up for any of the 3 ROM positions (all P > .05). The mean Constant score and UCLA score improved significantly in both groups after surgery, but there were no significant differences between the groups at the final follow-up (P = .634 and .302, respectively). MRI indicated a retear rate of 28.5% in the conventional group and 14.3% in the injection group (P < .001). Conclusion: This study revealed that an injection of adipose-derived MSCs loaded in fibrin glue during rotator cuff repair could significantly improve structural outcomes in terms of the retear rate. There were, however, no clinical differences in the 28-month period of follow-up. Although still in the early stages of application, MSC augmentation of surgical rotator cuff repair appears useful for providing an adequate biological environment around the repair site.
Health Beliefs Related to Salt-Restricted Diet and Associated Factors in Turkish Patients on Hemodialysis

Purpose: To examine health beliefs related to salt-restricted diet, to investigate their associations with demographic/disease-related characteristics and family support, and to determine the need for tailored interventions in Turkish patients on hemodialysis. Method: A cross-sectional study was conducted among 200 patients on hemodialysis. Data were collected through an information form, the Perceived Social Support from Family Scale and the Beliefs about Dietary Compliance Scale, including two subscales: perceived benefits and barriers. Descriptive statistics, Student’s t test, Pearson’s correlation coefficients, and linear regression analysis were used for data analysis. Results: The item mean perceived benefit score was higher than the item mean perceived barrier score. Limiting salt intake, family support, and the presence of residual urine output were associated with health beliefs. Conclusions/Implications: The likelihood of adherence to salt-restricted diet was high. A better understanding of health beliefs about salt-restricted diet and their related factors may facilitate the implementation of tailored interventions.
Utilizing IT to Enhance Knowledge Sharing for School Educators in Developing Countries

Knowledge has been considered a critical factor for any organization's survival however its retention and utilization has remained a challenge to many organizations in developing countries education institutions inclusive. These challenges are mostly attributed to the fact that knowledgeable employees often leave organizations before they could share their valuable knowledge and expertise. In schools of developing countries in particular, educators struggle for subsistence and many leave to seek for greener pastures. Such exodus of educators has led to knowledge loss and has widened the knowledge gap between the schools for the rich and those for the poor. This has been worse especially in the most challenging subjects like Science and Mathematics. Closing this gap, schools need to depend on the knowledge of other experienced educators that are still in the Education system in order to enhance the capabilities of those that are inexperienced. For this reason, leveraging Information Technology (IT) to facilitate the sharing of knowledge, communicate ideas, exchange views and information between educators is paramount. There is a need for schools in developing countries’ to have guidelines of how IT could be utilized for knowledge sharing. The major objective of this paper is therefore to report on the utilization of IT to enhance Knowledge Sharing (KS) among educators in developing countries taking a case of South Africa. The Social Exchange Theory (SET), Theory of Reasoned Action (TRA) and The Unified Theory of Acceptance and Use of Technology (UTAUT) were used to design a conceptual framework for the study. Data was collected from secondary schools’ educators in Tshwane South district of South Africa and was analyzed quantitatively. The results indicated that, knower's attitude is a high significant contributing factor whereas dependence of the knower is the least and insignificant in the utilization of IT to enhance knowledge sharing. Practically, this study could be leveraged by schools and governments to entrench tacit knowledge and to address the brain drainage associated with the continuous exodus of the skilled and experienced educators. Further still, the designed framework could be used by Information Systems scholars to extend research of knowledge sharing and management.
Two unrelated children with overlapping 6q25.3 deletions, motor speech disorders, and language delays

Interstitial and terminal 6q25 deletions are associated with developmental delays, hypotonia, eye pathologies, craniofacial dysmorphologies, and structural brain anomalies. In most cases, speech and language deficits are not described in detail. We report on a case (Patient 1, age 7 years) with a de novo 6q25.3‐qter deletion, 11.1 Mb long and encompassing 108 genes, and a case (Patient 2, age 5 years) with an inherited interstitial 6q25.3 deletion, located within Patient 1's deletion region and 403 kb long, the smallest 6q25 deletion reported to date. Both children have hypotonia, motor speech disorders, and expressive language delays. Patient 1's speech was characterized by childhood apraxia of speech (CAS) and dysarthria. Other findings include developmental delay, ataxic cerebral palsy, optic nerve dysplagia, and atypical brain morphologies regarding the corpus callosum and gyration patterns, a clinical profile that closely matches a previously reported case with a nearly identical deletion. Patient 2 had speech characterized by CAS and typical nonverbal processing abilities. His father, a carrier, had typical speech and language but showed difficulties with complex motor speech and hand motor tasks, similar to other adults with residual signs of CAS. The small deletion in this family contains the IGF2R‐AIRN‐SLC22A2‐SLC22A3 gene cluster, which is associated with imprinting and maternal‐specific expression of Igf2R, Slc22a2, and Slc22a3 in mice, whereas imprinting in humans is a polymorphic trait. The shared phenotypes in the two patients might be associated with the deletion of the gene cluster.
North Carolina Medical Student Views on Abortion

BACKGROUND Abortion is a controversial yet common procedure within the United States and North Carolina. Although much effort has been directed at understanding the views of physicians and the general public, the views of medical students on abortion are understudied. This study examines the views of medical students at different stages in training on abortion at a public institution, the University of North Carolina at Chapel Hill School of Medicine. METHODS We surveyed incoming, second year, fourth year, and leave-of-absence medical students at the University of North Carolina at Chapel Hill about their views on abortion. We utilized an IRB-approved, anonymous online Qualtrics-based, cross-sectional survey during the spring of 2014. RESULTS We received 315 responses (58% response rate) from 98 incoming (54.5%), 126 second year (70.0%), and 91 fourth year and leave-of-absence (49.2%) students. The majority of students, regardless of stage of training, felt abortion was morally acceptable (incoming 64.3%, second year 74.0%, and fourth year and leave-of-absence 70.0%). Of the students who found abortion to be acceptable, second year (80.9%) and fourth year and leave-of-absence (85.5%) students found second-trimester abortion more acceptable than incoming students (57.15%, P = .002); second year students (42.2%) had greater acceptability of third-trimester abortions compared to incoming (26.2%) and fourth year and leave-of-absence students (22.2%; P = .03). Religiosity and Republican political affiliation were associated with more conservative views on abortion (P = .002); however, gender or intention to enter into an obstetrics/gynecology residency were not. LIMITATIONS Our study reflects views from a single institution, the University of North Carolina at Chapel Hill School of Medicine. This limits the generalizability of our findings to the greater population of medical students across the country. CONCLUSION Despite the controversy surrounding abortion, our work suggests that medical students at the University of North Carolina at Chapel Hill School of Medicine have accepting views of abortion.
Public Perception of Telemedicine and Surgical Telementoring in the Pediatric Population: Results of a Parental Survey.

INTRODUCTION Telemedicine and surgical telementoring strive to provide equal access to specialized healthcare, regardless of patient location. It also aims to provide providers in remote locations real-time, second opinions from more experienced physicians who are otherwise not readily available. The goal of this study is to gauge the public perception of this technology in the pediatric population. METHODS Patient families in our pediatric surgery and gastroenterology clinics were asked to complete a seven-question survey after being shown a 1-minute video describing telemedicine and surgical telementoring. RESULTS A total of 129 people were surveyed. Among respondents, 89% were amenable to telemedicine for routine physician visit, 70% said "yes" for a postoperative visit, and 67% agreed to telemedicine and telementoring as a way to be evaluated by a specialist. Regarding surgical telementoring, 49% would consider it for their child, 58% would consider it for themselves, and 10% said "yes" for themselves, but "no" for their child. In addition, 24% and 19% were unsure about surgical telementoring for their child and themselves, respectively. Those with history of surgery without complications were more likely to say "yes" than "no" to telemedicine for a postoperative visit and surgical telementoring. Although a higher proportion of those with an annual income of >$100K said "no" to surgical telementoring for their child and themselves, this was not statistically significant (P = .23 and .25, respectively). Desire to see a physician in person was cited by 63% as a reason against telemedicine, although 35% reported concern about a physician's competence as a reason against surgical telementoring. CONCLUSION Overall, surgical telementoring was only supported by about half of the respondents. We predict that with increased education about surgical telementoring, this technology will have increased public support in the pediatric population.
Subclinical carotid atherosclerosis in patients with chronic obstructive pulmonary disease: a meta-analysis of literature studies

Abstract Background: Chronic obstructive pulmonary disease (COPD) patients have an increased cardiovascular (CV) morbidity and mortality. Common carotid intima-media thickness (CCA-IMT) and carotid plaques are surrogate markers of subclinical atherosclerosis and predictors of CV events. Methods and results: We performed a meta-analysis to evaluate the association between COPD and subclinical atherosclerosis. Studies evaluating the impact of COPD on CCA-IMT and on the prevalence of carotid plaques were systematically searched. Results: Twenty studies (2082 COPD patients and 4844 controls) were included, 12 studies with data on CCA-IMT (13 data-sets on 1180 COPD patients and 2312 controls) and 12 studies reporting on the prevalence of carotid plaques (1231 COPD patients and 4222 controls). Compared to controls, COPD patients showed a significantly higher CCA-IMT (mean difference [MD]: 0.201 mm; 95%CI: 0.142, 0.260; p < .001), and an increased prevalence of carotid plaques (Odds Ratio [OR]: 2.503; 95%CI: 1.333, 2.175; p < .0001). Meta-regression models showed a direct association between disease severity [as expressed by Global Initiative for Chronic Obstructive Lung Disease (GOLD) class] and the difference in the risk of carotid plaques presence between COPD patients and controls. Conclusions: COPD is significantly associated with subclinical atherosclerosis. These findings may be useful to plan adequate CV prevention strategies. Key messages COPD patients show a higher CCA-IMT and an increased prevalence of carotid plaques compared with controls. A more severe pulmonary disease is associated with a higher prevalence of carotid plaques in COPD patients. Screening for subclinical atherosclerosis may be worthy in COPD patients to plan specific prevention strategies.
Lipopolysaccharide- and Tumor Necrosis Factor-α-Induced Changes in Prolactin Secretion and Dopaminergic Activity in the Hypothalamic-Pituitary Axis

Bacterial lipopolysaccharide (LPS) affects pituitary hormone secretion, including prolactin release, by inducing synthesis and release of cytokines such as tumor necrosis factor-α (TNF-α). Since prolactin is mainly under tonic inhibitory control of dopamine, we investigated the effect of LPS and TNF-α on the hypothalamic-pituitary dopaminergic system. LPS (100–250 µg/rat, i.p.) decreased serum prolactin levels after 1 or 3 h. Sulpiride, a dopaminergic antagonist, increased serum prolactin and blocked the inhibitory effect of LPS. LPS increased hypothalamic dopamine and DOPAC concentrations and the DOPAC/dopamine ratio both in mediobasal hypothalamus and the posterior pituitary. LPS also enhanced dopamine and DOPAC concentration in the anterior pituitary. LPS elevated plasma levels of epinephrine, norepinephrine and dopamine but it did not modify the concentration of epinephrine or norepinephrine in the tissues studied. The administration of TNF-α (i.c.v., 1 h, 100 ng/rat) decreased serum prolactin but did not affect plasma catecholamine levels. TNF-α did not modify the DOPAC/dopamine ratio in hypothalamus or posterior pituitary but increased dopamine and DOPAC concentrations in the anterior pituitary. Incubations of hypothalamic explants showed that TNF-α did not modify in vitro basal dopamine release and reduced K+-evoked dopamine release. On the contrary, incubations of posterior pituitaries showed that TNF-α significantly increased basal and K+-evoked dopamine release. These results indicate that LPS and TNF-α increase dopamine turnover in the hypothalamic-pituitary axis. This increase in dopaminergic activity could mediate the inhibitory effect of LPS and TNF-α on prolactin release. Furthermore, the increase in dopaminergic activity elicited by LPS could be mediated by an increase in hypothalamic TNF-α during endotoxemia.
Anemia in Antiretroviral Naïve HIV/AIDS Patients: A Study from Eastern India

Background: Hematological manifestations are common throughout the course of HIV infection. Impact of anemia is the most significant among them. The present study was undertaken to evaluate the etiologies underlying anemia in HIV/AIDS. Methods This was a non randomized cross sectional observational study conducted in a tertiary care hospital of India over a period of 2 years. One hundred and fifty HIV patients were screened. Thorough clinical and laboratory evaluation was done in 50 randomly selected anemic cases. Results: Proper etiological diagnosis could be reached in 46 patients. Among them correlation between Hb% and CD4 count was statistically insignificant (p = 0.074, r = 0.47) whereas it was significant with absolute lymphocyte and CD4 count (p = 0.006, r = 0.41). There was better correlation of bone marrow iron status with percent saturation of transferrin (p = 0.003, r = 0.54) than with serum ferritin (p = 0.055, r = 0.09). Bone marrow iron status did not have any relationship with CD4 count. Anemia of chronic disease was the commonest etiology (37%) followed by HIV related myelodysplastic syndrome (31%), iron deficiency anemia (13%), bone marrow suppression due to direct involvement by some infective process (7%). Aplastic anemia, multiple myeloma, Hodgkin’s disease, pure red cell aplasia, hemophagocytic lymphohistiocytosis and vitamin B12 deficiency were detected in one case (2%) each. Conclusions: Etiologies of anemia in HIV/AIDS are multifactorial with anemia of chronic disease being the commonest. For screening of iron deficiency in this group, percent saturation is a better tool than serum ferritin. Absolute lymphocyte count can sometimes be used as a surrogate marker of immunological status in antiretroviral naive HIV patients, particularly in resource poor areas.
All‐oral daclatasvir plus asunaprevir for chronic hepatitis C virus (HCV) genotype 1b infection: a sub‐analysis in Asian patients from the HALLMARK DUAL study

Daclatasvir plus asunaprevir (DCV + ASV) has demonstrated potent antiviral activity in patients with hepatitis C virus (HCV) genotype 1b (GT‐1b) infection in the HALLMARK DUAL trial. This post hoc analysis was conducted to determine the efficacy and safety of this treatment in Asian patients.
Clinicoserological factors associated with response to steroid treatment and recurrence in patients with IgG4-related ophthalmic disease

Purpose To investigate the factors associated with response to steroid treatment and recurrence in patients with IgG4-related ophthalmic disease (ROD). Methods Twenty-eight patients with biopsy-proven IgG4-ROD treated between March 2010 and January 2017 were included in this retrospective study. Clinical features, serum IgG4 levels, systemic involvement, treatments and treatment outcome, factors associated with response to treatment and recurrence were assessed. Result Thirteen men and 15 women (mean age 50.8 years) were evaluated over mean follow-up period of 27.3 months. Elevated serum IgG4 levels (>1.35 g/L) and systemic disease were noted in 9 (32%) and 18 patients (64%), respectively. The lacrimal gland was involved in all patients, and 22 patients (78.6%) had bilateral involvement. Most patients (82%) responded well to systemic steroids, but 12 (43%) relapsed after the initial steroid treatment, requiring additional therapies to achieve remission. Complete response to initial steroid treatment was associated with elevated serum IgG4 levels before treatment (P=0.001) and bilateral orbital involvement (P=0.050). Recurrence was associated with elevated serum IgG4 levels before treatment (P=0.007), lower dose (P=0.057) and shorter duration of initial steroids (P=0.042). Patients with recurrence eventually required significantly more steroids than those without recurrence (P=0.011). Conclusions Patients with IgG4-ROD responded well to systemic steroid treatment, but recurrence was common, particularly among those with elevated serum IgG4 levels and shorter duration of initial steroid treatment. Low-dose maintenance treatment with systemic steroids should be considered to avoid recurrence in patients with elevated serum IgG4 levels.
Primary cutaneous plasmacytosis: report of three cases and review of the literature.

BACKGROUND Cutaneous plasmacytosis is a rare disease characterized by peculiar multiple eruptions and hypergammaglobulinemia. More than 40 cases have been reported, mainly in Japan, although information concerning the disorder was limited to individual case reports. OBJECTIVE AND METHODS To clarify the clinicopathological and laboratory features, we reviewed 41 cases. RESULTS All patients were Japanese and the male-to-female ratio was 1:0.6. The onset ages ranged from 20 to 62 years, with a mean and median of 37 and 37 years. A superficial lymphadenopathy was detected in 58% (22/38), and polyclonal hypergammaglobulinemia was found in 93% (38/41). No cases were associated with any apparent underlying diseases. The course was chronic without spontaneous remission. Four patients died, 3 of whom succumbed to leukemia, respiratory failure or renal failure, respectively. CONCLUSION The results suggest that the condition appears to be a variant of reactive plasmacytic disorders of unknown origin.
Long-term effect of intravenous calcitriol on the treatment of severe hyperparathyroidism, parathyroid gland mass and bone mineral density in haemodialysis patients.

We conducted this study on 15 chronic haemodialysis patients to evaluate the efficacy of i.v. calcitriol over a 1-year period in the treatment of severe secondary hyperparathyroidism (HPT), in particular its effect on bone mineral density (BMD) and parathyroid gland mass. Mean age was 39 +/- 11.9 (20-65) years and dialysis duration was 58 +/- 3 (19-130) months. i.v. calcitriol was given at a dose of 1 microg post-dialysis 3 times/week for 3 weeks; the dose was then adjusted to maintain the total serum calcium at less than 2.88 mmol/l. The maximum dose was 3 microg 3 times/week. Serum calcium (Ca) and phosphorus (P) were determined prior to treatment, then weekly for 6 weeks and every 2 weeks thereafter. Skeletal survey, dual photon densitometry and parathyroid ultrasound (US) were done prior to treatment and after 1 year. Bone biopsy was done in 10 patients at the beginning of treatment. There was a significant reduction (p < 0.01) in pre-treatment mid-region serum parathyroid hormone (PTH) from 1,476 +/- 895 to 489 +/- 485 P mol/l, as well as alkaline phosphatase (p < 0.04) from 236.5 +/- 221 to 116.3 +/- 49 U/l. This was without a significant increase in serum Ca (2.15 +/- 0.25 to 2.44 +/- 0.26 mmol/l, p = 0.08). Three patients had recurrent hypercalcaemia which responded to reduction of Ca in dialysate. There was a significant increase in BMD over the spine from 1.071 +/- 0.25 to 1.159 +/- 0.22 g/cm2 (p < 0.003) with a percent increase of 9.3 +/- 8.9% as well as over the femoral neck from 0.834 +/- 0.002 to 0.89 +/- 0.09 g/cm2 (p < 0.001) with a percent increase of 7.45 +/- 6.81%. Five patients had enlarged parathyroid glands by US and in 3 of these, there was a significant reduction to normal with treatment. Bone biopsy was done in 10 patients. Six patients had predominant hyperparathyroid bone disease and 4 had mixed uraemic osteodystrophy. In conclusion, long-term i.v. treatment with calcitriol is effective in the treatment of severe secondary HPT. PTH decreased without a significant increase in serum Ca. BMD also increases during this therapy.
