Objective Chronic Interstitial Nephritis in Agricultural Communities (CINAC) causes major morbidity and mortality for farmers in North-Central province (NCP) of Sri Lanka. To prevent the CINAC, reverse osmosis (RO) plants are established to purify the water and reduce the exposure to possible nephrotoxins through drinking water. We assessed RO plant maintenance and efficacy in NCP. Methods We have interviewed 10 RO plant operators on plant establishment, maintenance, usage and funding. We also measured total dissolved solids (TDS in ppm) to assess the efficacy of the RO process.Results Most RO plants were operated by communitybased organizations. They provide clean and sustainable water source for many in the NCP for a nominal fee, which tends to be variable. The RO plant operators carry out RO plant maintenance. However, maintenance procedures and quality management practices tend to vary from an operator to another. RO process itself has the ability to lower the TDS of the water. On average, RO process reduces the TDS to 29 ppm. Conclusions The RO process reduces the impurities in water available to many individuals within CINAC endemic regions. However, there variation in maintenance, quality management, and day-to-day care between operators can be a cause for concern. This variability can affect the quality of water produced by RO plant, its maintenance cost and lifespan. Thus, uniform regulation and training is needed to reduce cost of maintenance and increase the efficacy of RO plants.
Background: Cardiovascular disease (CVD) risk assessment remains a critical step in guiding decisions to initiate primary prevention interventions in people living with HIV (PLWH). Setting: We investigated whether coronary artery calcium (CAC) scoring allowed a more accurate selection of patients who may benefit from statin therapy, compared with current risk assessment tools alone. Methods: Cross-sectional analysis of PLWH over 50 years old who underwent CAC scoring between 2009 and 2019. Framingham Risk score (FRS), QRISK2 and D:A:D scores were calculated for each participant at the time of CAC scoring and statin eligibility determined based on current European guidelines on the prevention of CVD in PLWH. Results: A total of 739 patients were included (mean age 56 ± 5, 92.8% male, 84% white). Among 417 (56.4%) candidates for statin therapy based on FRS ≥10%, 174 (23.5%) had no detectable calcification (CAC = 0). Conversely, 145 (19.6%) patients with detectable calcification (CAC > 0) were identified as low-risk (FRS < 10%). When compared with FRS, CAC scoring reclassified CVD risk in 43.1% of patients, 145 (19.6%) to a higher risk group that could benefit from statin therapy and 174 (23.5%) statin candidates to a lower risk group. QRISK2 and D:A:D scores performed similarly to FRS, underestimating the presence of significant coronary calcification in 21.1% and 24.9% respectively and overestimating risk in 16.9% and 18.8% patients with CAC = 0. Conclusions: Establishing a decision-model based on the combination of conventional risk tools and CAC scoring improves risk assessment and the selection of PLWH who would benefit from statin therapy.
We demonstrated the feasibility of using the CONTISON echography transducer for the guidance CS cannulation. This technique could expedite CS cannulation and reduce radiation exposure. Further studies comparing ultrasound versus fluoroscopy for CS cannulation appear warranted.
Background Shone’s complex is a rare congenital heart disease consisting of a variety of left ventricular inflow and outflow tract lesions. Patients typically present in childhood requiring early surgical intervention; however, with improved surgical techniques, these patients are surviving later into adulthood. This increased survival comes with a new set of medical complications that providers need to be aware of. Case presentation A 27 year old man with a complex cardiac history including an incomplete Shone’s complex and persistent symptomatic atrial flutter presented with sharp chest pain radiating to his back. He was found to have type A aortic dissection on imaging in the setting of severe patient-prosthesis mismatch. He had multiple valvular surgeries in childhood. The patient was being followed-up as an outpatient for an enlarging chronic aortic aneurysm and was non-compliant with his medications. He was taken emergently to the operating room for a skirted Bentall procedure, aortic valve replacement, and right sided MAZE. Conclusions Shone’s complex is a rare congenital heart disease associated with significant morbidities including atrial flutter, patient-prosthesis mismatch, and aortic dissection. As patients continue to live longer into adulthood with this disease, it is important to raise awareness of this rare syndrome for providers and highlight its potential complications. Further research is needed to determine appropriate guidelines for when to intervene on aortopathy-associated CHD.
