A cross-sectional study on coronary artery disease diagnosis in patients with peripheral artery disease

PurposeCompared with healthy individuals, patients with peripheral artery disease (PAD) generally have a very high risk of subclinical Coronary artery disease (CAD) and cardiovascular events. To determine the correlation between CAD in PAD patients, thereby promoting the lifetime of PAD patients and reducing the serious impacts of CAD.MethodsThis clinical-based cross-sectional study comprised 100 consecutive patients in India from 2014 to 2016. In this research, PAD patients were screened for CAD by treadmill stress test and cardiac colour Doppler examination. In addition, this study performed coronary angiography followed by peripheral angiography for patients who could not perform the treadmill test.ResultsWith the statistical results, the study observed a high prevalence of CAD in PAD patients that can be detected only with angiography. Further, 30.93% of asymptomatic CAD prevalence was observed in PAD patients. The study strengthens the need for coronary angiography in all symptomatic lower limb PAD cases to detect early CAD, particularly in patients with diabetes and dyslipidemia.ConclusionThere exists a strong correlation between PAD and CAD. Hence, precise diagnosis followed by supervision of PAD patients is significant for avoiding local progression of cardiovascular risk.     

Comparison study of patient demographics and patient-related risk factors for peri-prosthetic joint infections following primary total shoulder arthroplasty

BackgroundWhile studies have demonstrated favorable outcomes in utilization of primary total shoulder arthroplasty (TSA) for the treatment of glenohumeral osteoarthritis (OA), adverse events such as infections can still occur. Periprosthetic joint infections (PJIs) are associated with worse outcomes and patient morbidity. The purpose of this study was to: (1) compare patient demographics amongst TSA patients with and without PJIs following primary TSA; and (2) identify patient-related risk factors for PJIs following primary TSA.MethodsPatients undergoing primary TSA for the treatment of glenohumeral OA were identified using the Mariner administrative claims database by CPT code 23,472. Laterality modifiers were utilized to ensure PJIs were developing in the correct laterality as those patients undergoing primary TSA. Inclusion for the study group consisted of patients who developed PJIs within 2-years after the index procedure, whereas patients who did not develop PJIs served as the comparison cohort. Primary outcomes analyzed included patient demographics and patient-related risk factors for PJIs following primary TSA. A stepwise backwards elimination multivariate binomial logistic regression analyses was performed to determine the odds (OR) of PJIs in patients undergoing primary TSA. A P value less than .05 was considered statistically significant.ResultsThe query yielded 15,396 patients who underwent primary TSA for glenohumeral OA, of which 191 patients developed PJIs and 15,205 did not develop PJIs. The study found statistically significant differences amongst patients who did and did not develop PJIs following primary TSA with respect to age, sex, and presence of comorbid conditions. Risk factors associated with developing PJIs following primary TSA included: pathologic weight loss (OR: 2.06, P < .0001), obesity (OR: 1.56, P = .0001), male sex (OR: 1.52, P = .007), and peripheral vascular disease (OR: 1.46, P = .022).ConclusionAs the number of primary TSAs for the treatment of glenohumeral OA increase worldwide, identifying modifiable risk-factors to reduce the incidence of infection is critical. The study found various modifiable and non-modifiable risk factors associated with developing PJIs following primary TSA. This study is valuable to orthopedists in order to identify and risk-stratify patients with regard to PJI in the setting of primary TSA for OA.Level of EvidenceLevel III; Case-Control Study     

Effect of peer support on adults with diabetes-related peripheral neuropathy

ObjectiveTo explore the effect of peer support on exercise self-efficacy, physical activity level, and neuropathic symptoms in patients with diabetes-related peripheral neuropathy (DPN).MethodsA total of 60 adults with DPN were assigned to groups. Patients in the control group received routine education (RE), while patients in the intervention group received peer support (PS) combined with routine diabetes education. Data were collected at baseline and after intervention (12 weeks).ResultsAt 12 weeks, better outcomes were found in the PS group compared to the RE group for the following aspects: exercise self-efficacy, steps, total physical activity, fasting blood glucose and 2-hour postprandial blood glucose. Decreases in scores on Toronto Clinical Scoring System occurred between baseline and post-intervention in both groups.ConclusionPeer support is an effective way to improve exercise self-efficacy, number of steps, and general physical activity and to reduce blood glucose for patients with DPN. But the effects of peer support on neuropathic symptoms is are obvious. Further research is needed.Practice implicationsAs a low-cost, effective education approach, peer support strategies should be integrated into our healthcare system to meet the minimum needs of patients with DPN.     

外伤性晶状体脱位合并周边隐匿性视网膜病变的临床特征及预后分析

目的观察分析眼球钝挫伤合并外伤性晶状体脱位患者周边隐匿性视网膜病变的临床特点及预后。 方法本研究纳入2013年1月至2020年1月在柳州市人民医院眼科住院诊断为眼球钝挫伤合并外伤性晶状体脱位，并行23G微创玻璃体切割联合白内障摘除手术的72例（72眼）患者。根据裂隙灯和超声生物显微镜（UBM）检查，将患者分为晶状体不全脱位组和全脱位组，详细记录2组患者的术中周边视网膜病变情况，并分析其临床特征及疗效。 结果眼球钝挫伤合并外伤性晶状体脱位患者中有周边隐匿性视网膜病变的占72.22%，其中晶状体不全脱位组发生率高达80.95%，显著大于晶状体全脱位组的60.00%（P＜0.05）。2组患者的周边隐匿性视网膜病变均以隐匿性视网膜裂孔、变性和出血为最常见。所有患者术后视网膜情况稳定，视力预后较好。 结论眼球钝挫伤合并外伤性晶状体脱位患者常出现周边隐匿性视网膜病变，最常见的是视网膜裂孔、出血、变性。23G微创玻璃体切割联合白内障摘除手术是有效治疗手段，具有创伤小、并发症少的优势。     

Immunogenicity and reactogenicity after booster dose with AZD1222 via intradermal route among adult who had received CoronaVac

BackgroundCurrently, booster dose is needed after 2 doses of non-live COVID-19 vaccine. With limited resources and shortage of COVID-19 vaccines, intradermal(ID) administration might be a potential dose-sparing strategy.ObjectiveTo determine immunologic response and reactogenicity of ID ChAdOx1 nCoV-19 vaccine (AZD1222,Oxford/AstraZeneca) as a booster dose after completion of 2-dose CoronaVac(SV) in healthy adult.MethodsThis is a prospective cohort study of adult aged 18–59 years who received 2-dose SV at 14–35 days apart for more than 2 months. Participants received ID AZD1222 at fractional low dose(1×10¹⁰ viral particles,0.1 ml). Antibody responses were evaluated by surrogate virus neutralization test(sVNT) against delta variant and wild type, and anti-spike-receptor-binding-domain immunoglobulin G(anti-S-RBD IgG) at prior, day14, 28, 90, and 180 post booster. Solicited reactogenicity was collected for 7 days post-booster. Primary endpoint was the differences of sVNT against delta strain ≥ 80% inhibition at day14 and 90 compared with the parallel cohort study of 0.5-ml intramuscular(IM) route.ResultsFrom August2021, 100 adults with median age of 46 years(IQR 41–52) participated. Prior to booster, geometric mean(GM) of sVNT against delta strain was 22.4% inhibition(95 %CI 18.7–26.9) and of anti-S-RBD IgG was 109.3 BAU/ml(95.4–125.1). Post ID booster, GMs of sVNT against delta strain were 95.5% inhibition (95%CI 94.2–96.8) at day14, 73.1% inhibition (66.7–80.2) at day90, and 22.7% inhibition (14.9–34.6) at day180. The differences of proportion of participants achieving sVNT against delta strain ≥ 80% inhibition in ID recipients versus IM were + 4.2% (95 %CI -2.0to10.5) at day14, and ?37.3%(-54.2to-20.3) at day90. Anti-S-RBD IgG GMs were 2037.1 BAU/ml (95%CI 1770.9–2343.2) at day14 and 744.6 BAU/ml(650.1–852.9) at day90, respectively. Geometric mean ratios(GMRs) of anti-S-RBD IgG were 0.99(0.83–1.20) at day14, and 0.82(0.66–1.02) at day90. Only 18% reported feverish, compared with 37% of IM (p = 0.003). Common reactogenicity was erythema at injection site(53%) while 7% reported blister.ConclusionLow-dose ID AZD1222 booster enhanced lower neutralizing antibodies at 3 months compared with IM route. Less systemic reactogenicity occurred, but higher local reactogenicity.
