Tele-Nephrology: A Feasible Way to Improve Access to Care for Patients with Kidney Disease Who Reside in Underserved Areas.

BACKGROUND: The Miami VA Healthcare System serves veterans in three South Florida counties: Miami-Dade, Broward, and Monroe, with an estimated veteran population of 175,000. To overcome geographical barriers and facilitate the access to nephrology clinics, we implemented provider-patient tele-nephrology using secured videoconferencing. METHODS: A retrospective and descriptive study design was used to evaluate the effect of the tele-nephrology clinic intervention. Multiple clinical indicators were included in the analysis: blood pressure (BP) control, stabilization of the renal function, and electrolyte/metabolic control. One hundred one patients who were evaluated in the clinic between 2013 and 2015 were included in the analysis, and the indicators were collected retrospectively. RESULTS: One hundred one patients were included in the analysis, with 95% of patients being male (n = 96) and 5% female (n = 5). The mean age was 65.5 years. Fifty patients had chronic kidney disease (CKD) stage III (49.5%), 14 patients had CKD stage IV (13%), and 8 patients had CKD stage II (7.9%). A one-way analysis of variance between subjects was conducted and showed that the effect of the tele-nephrology clinic intervention on reducing BP was statistically significant (systolic BP less than 140 p value <0.0001). Renal function stabilized but the creatinine changes over time were not statistically significant (p value: 0.50). Potassium showed a significant improvement in this sample (p value: 0.0076). Phosphorous and bicarbonate did not show a statistically significant improvement (p value 0.79 and 0.91, respectively). CONCLUSION: With the tele-nephrology clinic intervention, we were able to effectively improve BP and stabilize renal function in patients with kidney disease who reside in underserved areas.

Ocular surface symptoms in veterans returning from operation Iraqi freedom and operation enduring freedom.

PURPOSE: To correlate situational exposures and psychiatric disease with self-reported ocular surface symptoms in a younger veteran population involved in Operation Iraqi Freedom and Operation Enduring Freedom (OIF/OEF). METHODS: Cross-sectional study of all veterans evaluated in the OIF/OEF clinic between December 2012 and April 2013 who completed the dry eye questionnaire and screening evaluations for environmental exposures, posttraumatic stress disorder (PTSD), and depression. The main outcome measures were the influence of environmental exposure and psychiatric disease on ocular surface symptoms. RESULTS: Of 115 participants, the average age was 33 years. While overseas, exposure to incinerated waste (odds ratio [OR] 2.67, 95% confidence interval [CI] 1.23-5.81, P = 0.02) and PTSD (OR 2.68, 95% CI 1.23-5.85, P = 0.02) were associated with self-reported ocular surface symptoms. On return to the United States, older age (OR per decade 2.66, 95% CI 1.65-4.31, P = 0.04) was associated with persistent symptoms and incinerated waste was associated with resolution of symptoms (OR 0.25, 95% CI 0.07-0.90, P = 0.04). When evaluating symptom severity, 26% of the responders complained of severe ocular surface symptoms, with PTSD (OR 3.10, 95% CI 1.22-7.88, P = 0.02) and depression (OR 4.28, 95% CI 1.71-10.68, P = 0.002) being significant risk factors for their presence. CONCLUSIONS: PTSD was significantly associated with ocular surface symptoms both abroad and on return to the United States, whereas air pollution in the form of incinerated waste, was correlated with reversible symptoms.

Allan-Herndon-Dudley syndrome and the monocarboxylate transporter 8 (MCT8) gene.

Allan-Herndon-Dudley syndrome was among the first of the X-linked mental retardation syndromes to be described (in 1944) and among the first to be regionally mapped on the X chromosome (in 1990). Six large families with the syndrome have been identified, and linkage studies have placed the gene locus in Xq13.2. Mutations in the monocarboxylate transporter 8 gene (MCT8) have been found in each of the six families. One essential function of the protein encoded by this gene appears to be the transport of triiodothyronine into neurons. Abnormal transporter function is reflected in elevated free triiodothyronine and lowered free thyroxine levels in the blood. Infancy and childhood in the Allan-Herndon-Dudley syndrome are marked by hypotonia, weakness, reduced muscle mass, and delay of developmental milestones. Facial manifestations are not distinctive, but the face tends to be elongated with bifrontal narrowing, and the ears are often simply formed or cupped. Some patients have myopathic facies. Generalized weakness is manifested by excessive drooling, forward positioning of the head and neck, failure to ambulate independently, or ataxia in those who do ambulate. Speech is dysarthric or absent altogether. Hypotonia gives way in adult life to spasticity. The hands exhibit dystonic and athetoid posturing and fisting. Cognitive development is severely impaired. No major malformations occur, intrauterine growth is not impaired, and head circumference and genital development are usually normal. Behavior tends to be passive, with little evidence of aggressive or disruptive behavior. Although clinical signs of thyroid dysfunction are usually absent in affected males, the disturbances in blood levels of thyroid hormones suggest the possibility of systematic detection through screening of high-risk populations.
