Comparison of Lipid Profile, Liver Enzymes, Creatine Kinase and Lactate Dehydrogenase Among Type II Diabetes Mellitus Patients on Statin Therapy.

BACKGROUND: Diabetes mellitus (DM) is an epidemic disease affecting millions worldwide; the majority being type 2 diabetes mellitus (T2DM). Diabetes mellitus has been shown to be an important risk factor for the development of a variety of cardiovascular diseases, which are becoming common in Ethiopia. Consequently, risk-reducing statin therapy is recommended for nearly all patients with T2DM at 40 years of age or older regardless of cholesterol level. However, some controversies exist regarding its safety. OBJECTIVE: The aim of this study was to assess and compare the levels of lipid profile, liver enzymes, creatine kinase-MB (CK-MB) and lactate dehydrogenase (LDH) among T2DM patients on statin therapy. METHODOLOGY: A hospital-based cross-sectional study was conducted on a total of 100 T2DM patients. The study participants were divided into four groups consisting of equal numbers of participants (n = 25). Group I, II, and III were T2DM patients who were on statin therapy for 14 days-6 months, 6-18 months and ˃18 months, respectively. Group IV consisted of T2DM patients who were not on statin therapy. Convenient sampling technique was implemented till the required number had been achieved. Sociodemographic data was collected by using a standardized questionnaire. Fasting blood was collected and lipid profile, liver enzymes, CK-MB, LDH and fasting blood sugar were analyzed. Data was entered using epi-data and analyzed by one way ANOVA followed by Tukey post hoc multiple comparison tests using SPSS V. 20.00. A P-value < 0.05 was considered statistically significant. RESULTS: The mean values of total cholesterol and TAG were significantly lower among group III as compared to group I (P-values = 0.019 & 0.01). Similarly, LDL-c was significantly lower among group III as compared to group I (P = 0.022) and group IV (P = 0.027). Serum liver enzymes, CK-MB and LDH were not significantly different among the study groups (P > 0.05). The mean values of alanine aminotransferase (ALT) and AST were found within normal range while mean ALP was higher in all study groups. Fasting blood glucose value was not significantly different among the study groups, but higher than normal cut-off value in all groups. CONCLUSION: Statin therapy taken for a longer time has an effect in lowering total cholesterol, LDL- c and TAG in T2DM patients. Statin therapy has not brought significant change on CK-MB, LDH, liver enzymes and other parameters among T2DM patients.

Blood and Tissue Enzymatic Activities of GDH and LDH, Index of Glutathione, and Oxidative Stress among Breast Cancer Patients Attending Referral Hospitals of Addis Ababa, Ethiopia: Hospital-Based Comparative Cross-Sectional Study.

The exact cause of breast cancer is unknown; it is a multifactorial disease. It is the most diagnosed and the second killer cancer among women. Breast cancer can be originated from tissues of breast or secondary from other organs via metastasis. Generally, cancer cells show aberrant metabolism and oxidative stress when compared to noncancerous tissues of breast cancer patients. The current study aims at evaluating glutamate and glucose metabolism through GDH and LDH enzyme activities, oxidant, and antioxidative status among breast cancer patients attending referral hospitals of Addis Ababa, Ethiopia. Result. Catalytic activities of glutamate dehydrogenase, lactate dehydrogenase, and oxidative stress index were significantly increased in both serum (4.2 mU/ml, 78.6 mU/ml, and 3.3 : 1, resp.) and cancerous tissues (1.4 mU/ml, 111.7 mU/ml, and 2.15 : 1, resp.) of breast cancer patients as compared to those in serum of control group (3.15 mU/ml, 30.4 mU/ml, and 2.05 : 1, resp.) and noncancerous tissues of breast cancer patients (0.92 mU/ml, 70.5 mU/ml, and 1.1 : 1, resp.) (P ≤ 0.05). Correspondingly, ratios of reduced to oxidized glutathione were significantly decreased in both serum (20 : 1) and cancerous tissues (23.5 : 1) of breast cancer patients when compared to those in serum of control group (104.5 : 1) and noncancerous tissues of breast cancer patients (70.9 : 1) (P ≤ 0.05). Conclusion. Catalytic activities of GDH and LDH, ratios of GSH to GSSG, and concentration of TOS among breast cancer patients were significantly higher than were those among control group and noncancerous tissues of breast cancer patients, while TAC of breast cancer patients is significantly lower than that of control group and normal tissues of breast cancer patients.

Minimally invasive surgery and its impact on 30-day postoperative complications, unplanned readmissions and mortality.

BACKGROUND: A critical appraisal of the benefits of minimally invasive surgery (MIS) is needed, but is lacking. This study examined the associations between MIS and 30-day postoperative outcomes including complications graded according to the Clavien-Dindo classification, unplanned readmissions, hospital stay and mortality for five common surgical procedures. METHODS: Patients undergoing appendicectomy, colectomy, inguinal hernia repair, hysterectomy and prostatectomy were identified in the American College of Surgeons National Surgical Quality Improvement Program database. Non-parsimonious propensity score methods were used to construct procedure-specific matched-pair cohorts that reduced baseline differences between patients who underwent MIS and those who did not. Bonferroni correction for multiple comparisons was applied and P < 0·006 was considered significant. RESULTS: Of the 532 287 patients identified, 53·8 per cent underwent MIS. Propensity score matching yielded an overall sample of 327 736 patients (appendicectomy 46 688, colectomy 152 114, inguinal hernia repair 59 066, hysterectomy 59 066, prostatectomy 10 802). Within the procedure-specific matched pairs, MIS was associated with significantly lower odds of Clavien-Dindo grade I-II, III and IV complications (P ≤ 0·004), unplanned readmissions (P < 0·001) and reduced hospital stay (P < 0·001) in four of the five procedures studied, with the exception of inguinal hernia repair. The odds of death were lower in patients undergoing MIS colectomy (P < 0·001), hysterectomy (P = 0·002) and appendicectomy (P = 0·002). CONCLUSION: MIS was associated with significantly fewer 30-day postoperative complications, unplanned readmissions and deaths, as well as shorter hospital stay, in patients undergoing colectomy, prostatectomy, hysterectomy or appendicectomy. No benefits were noted for inguinal hernia repair.

Functional outcomes of clinically high-risk prostate cancer patients treated with robot-assisted radical prostatectomy: a multi-institutional analysis.

BACKGROUND: To ascertain 3-year urinary continence (UC) and sexual function (SF) recovery following robot-assisted radical prostatectomy (RARP) for clinically high-risk prostate cancer (PCa). METHODS: Retrospective analyses of a prospectively maintained database for 769 patients with D'Amico high-risk PCa undergoing RARP at two tertiary care centers in the United States and Europe between 2001 and 2014. The association between time since RARP and recovery of UC (defined as 0 pad/one safety liner per day) and SF (defined as sexual health inventory for men (SHIM) score ⩾17) was tested in separate preoperative and post-operative Cox-proportional hazards regression models. Sensitivity analyses were conducted using continence 0 pad per day and erection sufficient for intercourse as end points for UC and SF recovery, respectively. RESULTS: Mean age of the cohort was 62.3 years, and 62.1% harbored ⩾PT3a disease. Nerve sparing (unilateral or bilateral) RARP was performed in 87.7% of patients. Kaplan-Meier estimates of UC recovery at 12, 24 and 36 months after surgery was 85.2%, 89.1% and 91.2%, respectively, while 33.8, 52.3 and 69.0% of preoperatively potent men (preoperative SHIM ⩾17; n=548; 71.3%) recovered SF. Similar results were noted in sensitivity analyses. Patient age and year of surgery were associated with UC and SF recovery; additionally, preoperative SHIM score, degree of nerve sparing, pT3b-T4 disease and surgical margins were associated with SF recovery over the period of observation. CONCLUSIONS: Patients with D'Amico high-risk PCa treated with RARP may continue to recover UC and SF beyond 12 months of surgery and show promising outcomes at 3-year follow-up. Appropriate patient selection and counseling may aid in setting realistic expectations for functional recovery post RARP.

Utilization of pelvic lymph node dissection in patients undergoing robot-assisted radical prostatectomy in India versus the United States - A Vattikuti Collective Quality Initiative database analysis.

BACKGROUND: The utilization and extent of pelvic lymph node dissection (PLND) varies depending on the disease and practice patterns. AIMS: This study compares practice patterns in utilization of PLND between Indian and United States (US) practices. SETTINGS AND DESIGN: We focused on 415 patients (204 India; 211 US) prostate cancer patients treated with robot-assisted radical prostatectomy, between 2015 and 2016, within the Vattikuti Collective Quality Initiative database. SUBJECTS AND METHODS: Utilization of PLND and number of nodes removed were evaluated for the entire cohort, and after stratifying for Country of treatment and D'Amico risk groups. Logistic regression tested the relationship between PLND and country of treatment, after adjusting for disease risk. RESULTS: Indian patients had a higher risk distribution (D'Amico high-risk 53.4% in India vs. 27% in the US; P< 0.001) compared to their US counterparts. Overall, 193/204 (94.6%) Indian patients underwent PLND versus 181/211 (85.8%) US patients (P = 0.003). When stratified based on disease risk, PLND was performed more frequently in Indian patients with low-risk disease (81.0% vs. 41.4%,P= 0.008), but not in those with intermediate and high-risk disease. On multivariable analysis, Indian patients had a 2.57-fold higher probability of undergoing PLND than their US counterparts (P = 0.02). The analysis of the number of lymph nodes removed showed similar trends. CONCLUSIONS: Indian patients are more likely to undergo PLND than US patients. This is, especially true for patients with low-risk disease, who are unlikely to benefit from this procedure. Efforts should focus on optimizing the utilization of PLND, and deliver it only when there is clinical indication.

Renal Squamous Cell Carcinoma of a Native Kidney After Renal Transplant: A Case Report.

BACKGROUND: Renal squamous cell carcinoma is a rare primary tumor of the kidney that rapidly invades local structures and has a poor prognosis. Presentation is usually nonspecific and is associated with renal stone disease and chronic infection. Immunosuppressed renal transplant recipients are more likely to develop a malignancy than the general population. Squamous cell carcinoma of the kidney in the context of a renal transplant and long-term immunosuppression has not previously been described in the literature. CASE REPORT: A 46-year-old white man with previous renal stones and recurrent urinary infections underwent a right nephrectomy and subsequent renal transplantation owing to failure of the remaining kidney. Five years posttransplant, an abdominal ultrasound scan was performed owing to recurrent urinary infections and ongoing pyuria. This was reported as normal, but he later developed a discharging sinus in his left flank. A computed tomography (CT) scan revealed a tracking perinephric abscess with an associated cystic lesion of the left kidney. A left nephrectomy was performed and histologic examination suggested an invasive squamous cell carcinoma of the renal pelvis. The patient later required major surgery for chronic infection, and further imaging revealed metastatic disease, resulting in the decision to manage palliatively. CONCLUSION: Given the nonspecific nature of the symptoms and the poor prognosis, health care professionals should have a lower threshold for diagnostic imaging in these patients. Abdominal ultrasonography was unhelpful and only a later CT scan revealed the underlying malignancy. This should be expedited if there is a persistent abnormality on urinalysis. Once diagnosed, a change in immunosuppressant regime to include sirolimus should be considered.

Direct Band Gap Gallium Antimony Phosphide (GaSbxP(1-x)) Alloys.

Here, we report direct band gap transition for Gallium Phosphide (GaP) when alloyed with just 1-2 at% antimony (Sb) utilizing both density functional theory based computations and experiments. First principles density functional theory calculations of GaSbxP(1-x) alloys in a 216 atom supercell configuration indicate that an indirect to direct band gap transition occurs at x = 0.0092 or higher Sb incorporation into GaSbxP(1-x). Furthermore, these calculations indicate band edge straddling of the hydrogen evolution and oxygen evolution reactions for compositions ranging from x = 0.0092 Sb up to at least x = 0.065 Sb making it a candidate for use in a Schottky type photoelectrochemical water splitting device. GaSbxP(1-x) nanowires were synthesized by reactive transport utilizing a microwave plasma discharge with average compositions ranging from x = 0.06 to x = 0.12 Sb and direct band gaps between 2.21 eV and 1.33 eV. Photoelectrochemical experiments show that the material is photoactive with p-type conductivity. This study brings attention to a relatively uninvestigated, tunable band gap semiconductor system with tremendous potential in many fields.

ZnO gap engineering by doping with III-V compounds.

Gap engineering of ZnO by codoping it with III-V materials is investigated using model and ab initio calculation. Our results show that the codoped materials (ZnO)1-x (III-V)x , where (III-V) stands for GaN, AlN, AlP, BN, BP exhibit energy band gaps that get smaller as the dopant concentrations x is increased. Even at a very small dopant concentration the obtained band gaps are found to be much smaller than that of ZnO making the studied (ZnO)1-x(III-V)x materials promising candidates for photoelectrochemical water splitting.

Clinical Profile and Management of Poisoning with Suicide Tree: An Observational Study.

INTRODUCTION: The clinical features, management, and the associations of dosage in poisoning with the cardiotoxic plant Cerbera odollam (suicide tree), responsible for more than half of plant poisoning deaths in the South Indian State of Kerala alone, have not been evaluated. There are only few studies on its clinical features and none on the usage of cardiac pacing in its management, given its rarity in the Western world. We depend on data for similar toxins to form our management protocols. AIMS: Our aim was to describe the clinical features of C. odollam poisoning, dosage, and its relations to clinical features and pacemaker initiation therapy and to study the characteristics of temporary pacemaker therapy in its management. SUBJECTS AND METHODS: This study was conducted in fifty consecutive cases who presented with a history of C. odollam poisoning from whom clinical data were obtained. Cases initiated on temporary cardiac pacemaker therapy due to the toxin effects were also studied. Effect of dosage on various clinical manifestations and pacing was analyzed. RESULTS: All cases were due to suicidal ingestion. Vomiting (54%), thrombocytopenia (50%), and sinus bradycardia (32%) were the most common features. The need for cardiac pacing had a significant association with dosage in kernels ingested (P < 0.05) and with thrombocytopenia (P < 0.05). There was no association between hyperkalemia and death. Thirty-six percent of cases had to be paced, of which 16% died. In-hospital mortality of odollam poisoning was 12%. CONCLUSIONS: C. odollam poisoning cases merit monitoring and treatment in Intensive Care Unit with facilities for electrocardiographic monitoring and temporary cardiac pacing. The clinical features and the factors associated with mortality are different from other cardiac glycosides.

Meiotic behavior of Brachiaria decumbens hybrids.

Brachiaria decumbens is a forage grass of inestimable value for livestock in Brazil due to its production of good quality forage even when planted on acid and poor soils, although it is susceptible to pasture spittlebugs. Only one cultivar, cv. Basilisk, has been used as the pollen donor in crosses with Brachiaria ruziziensis since 1988 at Embrapa Gado de Corte Research Center. Breeding within the species only became possible from 2009 when sexual accessions were successfully tetraploidized using colchicine. Three sexual genotypes were obtained and hybridization within B. decumbens was finally achieved. Here, we evaluated microspore tetrads using conventional cytology and found meiotic indexes above 78% for all three female genitors (cD24-2, cD24-27, cD24-45), but a low meiotic index (<22%) in the natural apomictic genitor D62 (cv. Basilisk) and in 49 hybrids. Analysis of the relationship between abnormal tetrad frequency and non-viable pollen grains yielded a highly significant Pearson correlation coefficient. The t-test proved significant for the progeny of cD24-45 x D62, with lower abnormalities and pollen sterility when compared to the other two progenies resulting from cD24-2 and cD24-27 crossed to D62, but these two did not differ. Apomictic hybrids such as S036 and X030 with low pollen sterility have the potential for use in cultivar development, whereas the sexual hybrids T012, X072, and X078 might be of use as female genitors in polycross blocks if they display good agronomic traits.

Green tea polyphenols and their potential role in health and disease.

There is a growing body of evidence that plant polyphenols such as resveratrol, anthocyanins, catechins, and terpenes like taxol are effectively used in the treatment of chronic conditions including cancer, Alzheimer, Parkinsonism, diabetes, aging, etc. The link between oxidative stress and inflammation is well accepted. Thus, the mechanism of action of these natural products is partly believed to be through their significant antioxidant properties. The main constituent of green tea, with clinical significance, is epigallocatechin gallate (EGCG). It has been associated with antitumor, anti-Alzheimer, and anti-aging properties, improve redox status at the tissue level possibly preventing system level structural damage. This review focuses on EGCG and its potential therapeutic role in health and disease.

Medical androgen deprivation therapy and increased non-cancer mortality in non-metastatic prostate cancer patients aged ≥66 years.

PURPOSE: To examine the potential relationship between androgen deprivation therapy and other-cause mortality (OCM) in patients with prostate cancer treated with medical primary-androgen deprivation therapy, prostatectomy, or radiation. METHODS: A total of 137,524 patients with non-metastatic PCa treated between 1995 and 2009 within the Surveillance Epidemiology and End Results Medicare-linked database were included. Cox-regression analysis tested the association of ADT with OCM. A 40-item comorbidity score was used for adjustment. RESULTS: Overall, 9.3% of patients harbored stage III-IV disease, and 57.7% of patients received ADT. The mean duration of ADT exposure was 22.9 months (median: 9.1; IQR: 2.8-31.5). Mean and median follow-up were 66.9, and 60.4 months, respectively. At 10 years, overall-OCM rate was 36.5%; it was 30.6% in patients treated without ADT vs. 40.1% in patients treated with ADT (p < 0.001). In multivariable-analysis, ADT was associated with an increased risk of OCM (Hazard-ratio [HR]: 1.11, 95% Confidence-interval [95% CI]: 1.08-1.13). Patients with no comorbidity (10-year OCM excess risk: 9%) were more subject to harm from ADT than patients with high comorbidity (10-year OCM excess risk: 4.7%). CONCLUSIONS: In patients with PCa, treatment with medical ADT may increase the risk of mortality due to causes other than PCa. Whether this is a simple association or a cause-effect relationship is unknown and warrants further study in prospective studies.

Below the poverty line and non-communicable diseases in Kerala: The Epidemiology of Non-communicable Diseases in Rural Areas (ENDIRA) study.

INTRODUCTION: India carries the greatest burden of global non-communicable diseases (NCDs). Poverty is strongly associated with NCDs but there are few prevalence studies which have measured poverty in India, particularly in rural settings. METHODS: In Kerala, India, a population of 113,462 individuals was identified. The "Epidemiology of Non-communicable Diseases in Rural Areas" (ENDIRA) study was conducted via ASHAs (Accredited Social Health Activists). Standardised questionnaires were used in household interviews of individuals ≥18years during 2012 to gather sociodemographic, lifestyle and medical data for this population. The Government of Kerala definition of "the poverty line" was used. The association between below poverty line (BPL) status, NCDs and risk factors was analysed in multivariable regression models. RESULTS: 84,456 adults were included in the analyses (25.4% below the poverty line). The prevalence of NCDs was relatively common: myocardial infarction (MI) 1.4%, stroke 0.3%, respiratory diseases 5.0%, and cancer 1.1%. BPL status was not associated with age (p=0.96) or gender (p=0.26). Compared with those above the poverty line (APL), the BPL group was less likely to have diabetes, hypertension or dyslipidaemia (p<0.0001), and more likely to smoke (p<0.0001). Compared with APL, BPL was associated with stroke (OR 1.33, 1.04-1.69; p=0.02) and respiratory disease (OR 1.23, 1.15-1.32; p<0.0001) in multivariable analyses, but not MI or cancer. CONCLUSIONS: In rural Kerala, BPL status was associated with stroke and respiratory diseases, but not with MI and cancer although it was associated with smoking status, compared with above poverty line status.

Alginate microparticles loaded with lipopolysaccharide subunit antigen for mucosal vaccination against Klebsiella pneumoniae.

Klebsiella pneumoniae (K. pneumoniae) is one of the commonest causes of nosocomial infections in human beings. Since K. pneumoniae infections are air borne type, controlling it by mucosal vaccination through nasal and pulmonary route could be a promising approach in order to simulate the natural infection. New vaccines such as subunit vaccines are safer than traditional vaccines, but they are less immunogenic. Therefore to enhance their immunogenicity, there is a need to develop potent and safe adjuvants and delivery systems. It has been established that micro-particles are one of the most potent adjuvants available for mucosal delivery of vaccines and they do so by improving uptake of encapsulated antigen by antigen presenting cells (APCs). Lipopolysaccharide (LPS), the antigenic fraction was extracted from K. pneumoniae by hot phenol extraction method. LPS loaded sodium alginate microparticles were prepared by emulsion ionic gelation method. Microparticles with particle size less than 5 µm were obtained. Loading efficiency of the LPS loaded microparticles ranged from 76 to 82 %. Comparative in vivo immunogenicity studies were carried for free LPS and encapsulated LPS, administered via intramuscular, intratracheal and intranasal routes in Swiss albino mice. The study revealed that LPS encapsulated microparticles exhibit greater efficacy when administered by intra-tracheal route as compared to free LPS vaccine.

Gluteal fold flap in perineal reconstruction for Crohn's disease-associated fistulae.

INTRODUCTION: Crohn's disease is increasing in incidence worldwide. It is associated with many complications including fistulae, which may require surgical intervention. Occasionally, formal perineal reconstruction is needed for extensive or definitive fistula surgery. Reconstruction for inflammatory disease presents unique challenges and often calls for innovative solutions. Gluteal fold flaps (GFFs), which have been widely used in vulvo-vaginal malignancy and anorectal cancer surgery, have not hitherto been reported for Crohn's disease-associated fistulae. CASE PRESENTATION: A 30-year-old female presented with a 5-year history of Crohn's-associated perianal and rectovaginal fistulae. She had a previous small bowel resection and ileostomy. A laparascopic pan-proctocolectomy was carried out followed by perineal reconstruction in a single stage procedure using a pedicled fasciocutaneous GFF. Seven months postoperatively, revisional surgery was carried out using the contralateral GFF due to two areas of persistent wound dehiscence. The outcome was complete resolution of the fistulae, stable wound closure and good cosmesis. DISCUSSION & CONCLUSION: This case demonstrates that it is practical to use the GFF for perineal reconstruction following excision of complex Crohn's-associated fistulae. The flap avoids the sequelae associated with sacrifice of regional muscle flaps and specifically circumvents the unavailability of the rectus abdominis flap in slim patients or those with in-situ ileostomies. It is easy and quick to raise and does not require an intra-operative change in the patient's position. The GFF ensured well vascularised skin cover, adequate flap volume with no loss of function and low donor site morbidity.
