The Effect of Tannin Content on the Nutritive Value of Some Leaf Protein Concentrates

The analysis of phytates in extrudates containing rye bran was done by a colorimetric method with the Wade reagent. The changes in profiles of myo-inositol phosphates indicate that, although no isomers with positive physiological functions (such as I(1,4,5)P3, I(1,2,3)P3 or I(1,3,4,5)P4) were formed, the beneficial impact of extrusion is the reduction of phytates, as compared to the raw material. The obtained snacks containing rye bran received acceptable to desirable sensory scores.     

A syndemic of psychosocial health problems is associated with increased HIV sexual risk among Nigerian gay,bisexual, and other men who have sex with men (GBMSM)

ABSTRACT

Nigerian gay, bisexual and other men who have sex with men (GBMSM) experience negative psychosocial health problems, which may increase their risk for HIV infection. Few studies have explored the syndemic effect of co-occurring psychosocial health problems on HIV sexual risk among Nigerian GBMSM. We investigated the co-occurrence of syndemic psychosocial health problems and their synergistic effect on HIV risk behaviors. We assessed depressive symptoms, post-traumatic stress disorder, alcohol dependence, tobacco use, and hard-drug use. The outcome variables were the number of male sexual partners and consistent condom use. In a multivariable model, experiencing 4 or more psychosocial health problems – compared to experience none or one psychosocial health problem – was significantly associated with increasing number of male sexual partners. We found no statistically significant association between the number of syndemic psychosocial health problems and consistent condom use. Our study findings provides evidence of a synergistic relationship between negative psychosocial health factors and HIV sexual risk behavior. These findings underscore the importance of developing HIV prevention programming aimed at reducing HIV transmission risk that incorporate substance use and mental health treatments, in order to improve the overall health and quality of life for Nigerian GBMSM.     

A Posttraumatic Dilated,Proptotic Eye Does Not Always Need a Lateral Canthotomy! A Review of Superior Orbital Fissure Syndrome for Emergency Physicians

BackgroundSuperior orbital fissure syndrome (SOFS) is a rare constellation of findings consisting of ophthalmoplegia, ptosis, a fixed dilated pupil, forehead anesthesia, and loss of the corneal reflex. This syndrome, though rare, is most often encountered in trauma with individuals sustaining a facial fracture.Case ReportWe present a case of a young woman who was diagnosed with SOFS after a fall in her house, hitting her face on a nightstand. Treatment consisted of high-dose i.v. steroids followed by a taper with close follow-up in the Ophthalmology clinic. We provide a brief review of SOFS, including treatment considerations and follow-up.Why Should an Emergency Physician Be Aware of This?SOFS can be easily overlooked in an individual presenting to the emergency department after facial trauma with proptosis. However, a thorough examination of the eye, visual acuity, and intraocular pressure will focus the physician on SOFS rather than the need for immediate decompression via lateral canthotomy. This report describes a traumatic cause of SOFS, the pathophysiology and treatment, and summarizes existing literature.

Bradypacing: indications and management challenges in Nigeria

Background: Permanent pacemaker implantation is a life-saving procedure that is performed worldwide. There is paucity of reports on pacemaker surgery in Nigeria. The aims of the study were to determine the indications for pacemaker insertion, the demographic distribution of the patients requiring it, the electrocardiographic (ECG) changes, and the management challenges in Nigeria. MATERIALS AND METHOD: One hundred consecutive patients who had pacemaker insertion done by our team from 1999 were included in the study. The patients' biodata, indications for pacemaker insertion, ECG changes, and the treatment profile were recorded. RESULTS: There was female preponderance (93.0%) among the patients studied. Third-degree heart block was the indication in 86.0% of the patients and most patients did well with single lead ventricular pacing which is generally cheaper than the dual chamber pacing. CONCLUSION: The majority of bradyarrhythmia patients in this environment can be maintained on single lead ventricular pacemaker.     

The risks of radiation therapy and lymphedema in shoulder surgery

BackgroundRadiation therapy has proven efficacy for cancer treatment but is not without short- and long-term side effects, including radiation-induced lymphedema. There has been limited evidence on the secondary effects of prior radiation therapy on shoulder surgery. The purpose of this study is to evaluate the short-term outcomes of shoulder arthroplasty and rotator cuff repair (RCR) in patients who have undergone ipsilateral radiation therapy and/or have preoperative upper extremity lymphedema.MethodsDuke Enterprise Data Unified Content Explorer was used to query for patients who underwent RCR at our institution. Patients with radiation therapy for breast or lung cancer prior to ipsilateral RCR or shoulder arthroplasty were included. Patients with less than 2 years of follow-up were excluded. Data variables included primary tumor type, dates of cancer diagnoses, radiation treatment, axillary lymph node dissection (aLND), presence of lymphedema, index shoulder operations, most recent follow-up, and surgical and medical complications within the 90-day postoperative period. Additional oncologic variables included total Gray (Gy) delivered.ResultsTwenty-one patients underwent radiation therapy and subsequent shoulder arthroplasty or RCR (13 RCR, 3 total shoulder arthroplasty, 5 reverse shoulder arthroplasty). There were 20 females and 1 male with an average age of 65.6 years (47-82) and average clinical follow-up of 4.4 years (2.0-7.4). Oncologic diagnoses included lung (4.8%) and breast (95.2%) cancer. Average radiation dose delivered was 53.3 Gy (38.5-64) in the cohort. The average time from last external beam radiation therapy to shoulder surgery was 4.3 years (0.3-18.0). One of 13 (7.7%) 90-day postoperative complications was reported in the RCR cohort: a superficial vein thrombosis. One of 8 (12.5%) 90-day complications was reported in the arthroplasty cohort: a clinically suspected but radiographically absent acromial stress fracture in a reverse shoulder arthroplasty that did not require operative intervention. Overall, there were no revisions, reoperations, or shoulder-related unplanned inpatient 90-day readmissions. Among 10 patients with prior aLND, 3 (30%) (2 RCR, 1 arthroplasty) experienced new or worsening upper extremity lymphedema within the immediate postoperative period.ConclusionA minority of patients having undergone prior radiation therapy and aLND who subsequently underwent ipsilateral shoulder surgery experienced worsening subjective upper extremity lymphedema. Although 10% of these radiation therapy patients experienced minor complications within 90 days of their shoulder surgery, none were severe enough to merit inpatient admission or revision surgery.     

Soluble urokinase plasminogen activator receptor is in contrast to high-sensitive C-reactive-protein associated with coronary artery calcifications in healthy middle-aged subjects

Objective

The main objective of this study was to investigate the association between two markers of low-grade inflammation; soluble urokinase plasminogen activator receptor (suPAR) and high-sensitive C-reactive protein (hs-CRP); and coronary artery calcification (CAC) score detected by cardiac computed tomography (CT) scan.

Design

A cross sectional study of 1126 randomly sampled middle-aged men and women.

Methods

CAC score was measured by a non-contrast cardiac CT scan and total 10-year cardiovascular mortality risk was estimated using the Systematic Coronary Risk Evaluation (SCORE). Plasma samples were analysed for suPAR and hs-CRP. The association of suPAR and hs-CRP to CAC was evaluated by logistic regression analyses adjusting for categorised SCORE. The additive effect of suPAR to SCORE was evaluated by comparing area under curve (AUC) and net reclassification improvement (NRI).

Results

The odds of being in a higher CAC category, i.e. having more severe CAC, increased 16% (odds ratio (OR) 1.16, p = 0.02) when plasma suPAR concentration increased 1 ng/ml, and this was more pronounced in women (OR 1.30, p = 0.01) than in men (OR 1.15, p = 0.05). In comparison, hs-CRP was not associated with CAC category (OR 1.00, p = 0.90). When adding suPAR to categorised SCORE, AUC increased from 0.66 to 0.70 (p = 0.04) in women and from 0.65 to 0.68 (p = 0.03) in men. NRI was significant in men (NRI 19.3%, 95% CI 6.1–32.6, p = 0.004) as well as in women (NRI 20.8%, 95%CI 1.0–40.7, p = 0.04), without significant gender difference.

Conclusions

suPAR, but not hs-CRP, appeared to be associated with CAC score independently of SCORE. The association was strongest in women.

Lack of association between cystatin C and different coronary atherosclerotic manifestations

Cystatin C (CysC) is known to be related to cardiovascular disease (CVD), including the presence and severity of coronary artery disease (CAD) and future clinical events. In this study, the association between CysC levels and (1) coronary artery calcification (CAC) in asymptomatic individuals from the general population as well as (2) different subgroups of patients with suspected or definite acute myocardial infarction (MI) was investigated. CysC levels were measured in serum from asymptomatic individuals as part of a screening study for CAC using non-contrast cardiac CT scan (N?=?1039) as well as in subgroups of hospitalized patients with a suspected MI (N?=?769). CysC was not associated with CAC in asymptomatic individuals after adjusting for relevant risk factors. No difference in CysC levels was observed between patients with type 1?MI (1.07?mg/L) and patients with normal troponin (with or without prior CAD: 1.14 and 1.01?mg/L, respectively). However, patients with type 2?MI and patient subgroups with elevated troponin but without MI had significantly higher CysC levels (1.24, 1.23 and 1.31?mg/L), even after adjusting for other risk factors. CysC was not associated with CAC in middle-aged asymptomatic individuals from the general population. Furthermore, CysC levels were found to be significantly lower in patients with type 1?MI compared to patients with type 2?MI and patients with elevated troponins but without MI. Thus, in two independent and clinically different populations, no association between CysC and coronary atherosclerotic manifestations could be demonstrated.
