BACKGROUND: Diabetes mellitus (DM) is a major predictor of cardiovascular morbidity and mortality. However, there are limited data on the impact of DM in patients who have chronic total occlusion (CTO) lesion on long-term outcomes. PATIENTS AND METHODS: A total of 822 CTO patients who underwent coronary angiography, treated by either percutaneous coronary intervention or optimal medical therapy, were enrolled and divided into two groups: (i) diabetic group (n=363) and (ii) nondiabetic group (n=459). Individual and composite major clinical outcomes were compared up to 5 years. RESULTS: Propensity score matching analysis was carried out generating two groups (298 pairs, n=596, C-statistic=0.655) with balanced baseline characteristics. Up to 5 years, the DM group showed a higher trend toward revascularization (19.5 vs. 13.5%, P=0.051) and major adverse cardiovascular events (MACE) (24.7 vs. 19.1%, P=0.097) compared with the nondiabetic group. However, there was no difference in the incidence of death and myocardial infarction between the two groups. Subgroup analysis showed that the chronic kidney disease (CKD) subgroup was associated with a higher incidence of all-cause death, cardiac death, myocardial infarction, revascularization, and MACE in comparison with diabetic patients without CKD and nondiabetic patients, respectively (total MACE: 39 vs. 20.5 vs. 19.2% , P=0.001). Insulin-dependent diabetic patients had a significantly higher incidence of MACE (hazard ratio=1.58; 95% confidence interval: 1.04–2.40; P=0.03) compared with the nondiabetic patients. CONCLUSION: Diabetic patients with CTO were associated with a trend toward a higher incidence of revascularization and total MACE up to 5 years. Insulin-dependent and diabetic patients with CKD subgroups had a significantly higher incidence of total MACE.

Chrysomya albiceps Wiedemann (Diptera: Calliphoridae) colonising poisoned rabbit carcasses

Mashaly Ashraf,Al‐Khalifa Mohammed,Al‐Qahtni Abdullah 한국곤충학회 2020 Entomological Research Vol.50 No.11

Chrysomia albiceps Wiedemann (Diptera: Calliphoridae) is one of the first insects to colonise human and animal carrion and thus one of the most important insects in forensic entomology. Since the presence of these blow flies have been reported in most of the provinces in Saudi Arabia, we analyse the succession patterns of C. albiceps on decomposing rabbit carcasses injected with heroin or administered orally with alcoholic beverages. Samples of flies from the carcasses of heroin or alcohol‐treated and untreated rabbits were obtained for 15 days post mortem. A total of 1,297 and 1,426 flies were attracted to rabbit carcasses during the heroin and alcohol tests, respectively. The blow flies appeared in different developmental instars (larvae, pupae and adults), and at all stages of decomposition. Administration of higher concentrations of heroin or higher amounts of alcohol were generally associated with an increase in the number of blow flies drawn to rabbit carcasses (P < 0.05). The highest number of blow flies were attracted during the decay stage of decomposition, and the lowest during the fresh stage. In the case of medicolegal investigation, when C. albiceps used as a forensic indicator, it is recommended that the impact of heroin or alcoholic beverages on the succession patterns be considered.

Mashaly Ashraf,Al‐Khalifa Mohammed,Al‐Qahtni Abdulmani,Alshehri Adel 한국곤충학회 2020 Entomological Research Vol.50 No.7

In medicolegal cases, an analysis of the presence of insects on human bodies may have potential legal significance. This study investigates the presence of insects on human bodies during autopsies in legal medicine. It was implemented in Riyadh, Saudi Arabia. Nine cadavers were examined, respectively, from four cases of homicide, two cases of burning, one suicide, one accident and one case of neglect. Insects associated with the human corpses were carefully collected and identified using valid taxonomic keys. Three of the cadavers were of children with ages ranging from seven months to nine years. In seven cases decomposition had occurred outdoors while in two cases it was indoors. Overall, eleven different species of insects were identified. Six of the cases exhibited species from five families within Diptera (Calliphoridae, Muscidae, Ulidiidae, Tachinidae and Sarcophagidae), specifically Chrysomya albiceps (Wiedemann), Musca domestica (Linnaeus), Tachinidae sp. (Bigot), Physiphora alceae (Preyssler) and Sarcophaga dux (Thompson). Six of the cadavers hosted beetles, which were identified as Dermestes maculatus(DeGeer), D. frischii (Kugelann), Necrobia rufipes (Fabricius), Nitidula bipunctata (Linnaeus), Pimelia interjecta (Solier) and Latridiidae sp. (Erichson). Moreover, the suicide corpse was colonised by more fly species than the other corpses, while the beetles colonised the homicide and accident corpses more than the other corpses. Analysis of the diversity of insects on human corpses may lead to advances in the understanding of forensic entomology and more sophisticated estimates of the minimum post-mortem interval.

<P>BackgroundLipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic vascular disease. However, there are limited data regarding the impact of Lp(a) levels on the incidence and severity of endothelium-dependent coronary vasomotor response.Patients and methodsA total of 2416 patients without significant coronary artery lesion (<50% stenosis) by coronary angiography and underwent acetylcholine (ACh) provocation test were enrolled and categorized according to their serum Lp(a) level into four quartile groups: less than 6.70, 6.70-13.30, 13.30-26.27, and more than 26.27mg/dl. The aim of this study is to estimate the incidence and severity of endothelium-dependent positive ACh provocation test in each group; moreover, to access the incidence of major adverse cardiovascular events, the composite of total death, myocardial infarction, and de novo percutaneous coronary intervention were compared between the four groups up to 5 years.ResultsThe group with higher Lp(a) had a higher incidence of coronary heart disease, myocardial infarction, and peripheral arterial disease history. However, there was no difference among the four groups as regards the incidence of positive ACh provocation test, spasm severity, spasm extent, and location. However, at up to 5 years of clinical follow-up, the higher-Lp(a) group showed higher total death, de novo percutaneous coronary intervention, recurrent angina, and total major adverse cardiovascular events compared with the lower-Lp(a) groups.ConclusionIn our study, there was no relationship between the elevated Lp(a) level and the vasospastic response to the intracoronary ACh provocation test; however, higher Lp(a) levels were associated with poor clinical outcomes up to 5 years.</P>

Monomorium ant's trail pheromones: Glandular source, optimal concentration, longevity and specificity

Ashraf Mohamed Ali Mashaly 한국응용곤충학회 2010 Journal of Asia-Pacific Entomology Vol.13 No.1

Many ants use pheromone trails to organize collective foraging. Trail pheromones are produced from different glandular sources and they may be specific to a single species or shared by a number of species. I investigated the source of trail pheromones in three Monomorium ant species: Monomorium niloticum (Emery), M. najrane (Collingwood & Agosti) and M. mayri (Forel). I also examined the optimal concentration,longevity and specificity of the pheromones. M. niloticum and M. najrane secrete trail pheromone from their venom glands, whereas M. mayri secrete trail pheromone from its Dufour's gland. The optimum concentration was 1.0 and 0.1 gaster equivalent (GE)/30 cm trail in M. niloticum, 1.0 GE in M. najrane and 5.0 GE in M. mayri. Longevity of the optimal concentration was about one day for all species. There is no species specificity among the three species of Monomorium in their trail pheromone.

Mahmoud, Ahmed H.,Mashaly, Ashraf M.,Rady, Ahmed M.,Al-Anazi, Khalid M.,Saleh, Amgad A. Asian Australasian Association of Animal Productio 2017 Animal Bioscience Vol.30 No.2

Objective: This study was designed to characterize the DNA polymorphisms of the melanocortin-1 receptor (MC1R) gene in indigenous Saudi Arabian sheep breeds exhibiting different color coats, along with individuals of the Sawaknee breed, an exotic sheep imported from Sudan. Methods: The complete coding region of MC1R gene including parts of 3' and 5' untranslated regions was amplified and sequenced from three the indigenous Saudi sheep; Najdi (generally black, n = 41), Naeimi (generally white with brown faces, n = 36) and Herri (generally white, n = 18), in addition to 13 Sawaknee sheep. Results: Five single nucleotide polymorphisms (SNPs) were detected in the MC1R gene: two led to nonsynonymous mutations (c.218 T>A, p.73 Met>Lys and c.361 G>A, p.121 Asp>Asn) and three led to synonymous mutations (c.429 C>T, p.143 Tyr>Tyr; c.600 T>G, p.200 Leu>Leu, and c.735 C>T, p.245 Ile>Ile). Based on these five SNPs, eight haplotypes representing MC1R $E^d$ and $E^+$ alleles were identified among the studied sheep breeds. The most common haplotype (H3) of the dominant $E^d$ allele was associated with either black or brown coat color in Najdi and Sawaknee sheep, respectively. Two other haplotypes (H6 and H7) of $E^d$ allele, with only the nonsynonymous mutation A218T, were detected for the first time in Saudi indigenous sheep. Conclusion: In addition to investigating the MC1R allelic variation in Saudi indigenous sheep populations, the present study supports the assumption that the two independent nonsynonymous Met73Lys and Asp121Asn mutations in MC1R gene are associated with black or red coat colors in sheep breeds.

최웅길,나승운,최병걸,최세연,변재경,Ahmed Mashaly,박윤지,장원영,김우현,최자연,박은진,나진오,최철웅,김응주,박창규,서홍석 연세대학교의과대학 2018 Yonsei medical journal Vol.59 No.4

Purpose: Prediabetes is an independent risk factor for cardiovascular disease. However, data on the long term adverse clinicaloutcomes of prediabetic patients undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DESs) arescarce. Materials and Methods: The study population comprised 674 consecutive non-diabetic patients who underwent elective PCI betweenApril 2007 and November 2010. Prediabetes was defined as hemoglobin A1c (HbA1c) of 5.7% to 6.4%. Two-year cumulativeclinical outcomes of prediabetic patients (HbA1c of 5.7% to 6.4%, n=242) were compared with those of a normoglycemic group(<5.7%, n=432). Results: Baseline clinical and angiographic characteristics were similar between the two groups, except for higher glucose levels(104.8±51.27 mg/dL vs. 131.0±47.22 mg/dL, p<0.001) on admission in the prediabetes group. There was no significant differencebetween the two groups in coronary angiographic parameters, except for a higher incidence of diffuse long lesion in the prediabetesgroup. For prediabetic patients, trends toward higher incidences of binary restenosis (15.6% vs. 9.8 %, p=0.066) and late loss(0.71±0.70 mm vs. 0.59±0.62 mm, p=0.076) were noted. During the 24 months of follow up, the incidence of mortality in prediabeticpatients was higher than that in normoglycemic patients (5.5% vs. 1.5%, p=0.007). Conclusion: In our study, a higher death rate and a trend toward a higher incidence of restenosis in patients with prediabetes upto 2 years, compared to those in normoglycemic patients, undergoing elective PCI with contemporary DESs.
