Background
A high body mass index (BMI) is seems to be associated with an increased incidence of coronary artery disease. If the affected person is young, the consequences are more tragic. There are variable information on the relation of incidence and severity of coronary artery disease in high BMI populations. We have examined the association between BMI and severity of coronary artery disease in young onset Acute Coronary Syndrome (ACS).
Methods
In this prospective observational study a total number of 150 patients, aged ≤45 years presented with acute coronary syndrome were enrolled to analyze association between Body Mass Index (BMI) and severity of coronary artery disease.
Results
The mean BMI in male was 24.6±3.6 and the mean BMI in female was 25.4±3.3. Among the 150 patients, 2(1.3%) was underweight, 78(52%) was normal, 60(40%) was overweight & 10(6.7%) was obese. All underweighted patients were diagnosed as STEMI. Among the normal BMI patients, 18(23.1%) had UA, 12(15.4%) had NSTEMI & 48 (61.5%) had STEMI. Among the overweight patients, 23(38.3%) had UA, 9(15%) had NSTEMI & 28(46.7%) had STEMI. And among the obese patients, 4(40%) had UA, 1 (10%) had NSTEMI & 5(50%) had STEMI. Considering involving coronary artery, left main coronary artery involvement was 0(0%), 6 (7.7%), 5 (8.3%) & 0(0%) in underweight, normal, overweight & obese patients respectively. Left anterior descending coronary artery involvement was 2(100%), 54 (69%), 45 (75%) & 7 (70%) in underweight, normal, overweight & obese patients respectively. Left circumflex coronary artery involvement was 1(50%), 33 (42%), 25 (41.7%) & 1 (9%) in underweight, normal, overweight & obese patients respectively. And right coronary artery involvement was 1(50%), 35 (44.9%), 31 (51.7%) & 5 (50%) in underweight, normal, overweight & obese patients respectively. In underweight patients 1(50%) had SVD and 1 (50%) had TVD. In normal BMI patients 40 (51.3%) had SVD, 11(14.1%) had DVD and 19 (24.4%) had TVD. In overweight patients 27 (45%) had SVD, 15 (25%) had DVD and 13 (21.7%) had TVD. And in obese patients 5 (50%) had SVD, 3(30%) had DVD and 0 (0%) had TVD. In all BMI group SVD was more common.
Conclusion
There is no statistically significant differences in severity of coronary artery in respect to body mass index (BMI), in patients presented with acute coronary syndrome.

Abstract
Abstract
Background
The CQC inspection of the Royal Lancaster Infirmary (RLI) in May 2021 rated the performance of the stroke department unsatisfactory, leading to a number of changes. A retrospective audit was performed to determine the impact of these changes for thrombolysed stroke patients.
Aim
This retrospective audit assessed the performance of the stroke department at the RLI against the parameters set by the ‘Sentinel Stroke National Audit Program’ (SSNAP), comparing 6-month periods before and after the CQC inspection in May 2021.
Method
Using electronic medical records and SSNAP data, we reviewed every thrombolysed stroke patient at the RLI between November 2020 until April 2021 and from May 2021 until November 2021, assessing 10 parameters and comparing the results with SSNAP targets. Since May 2021, changes to practice introduced included opening a new, larger stroke unit located directly opposite the Emergency Department, ring-fencing stroke beds, doubling the number of stroke specialists and stroke consultants reviewing all suspected stroke patients face-to-face within working hours.
Results
46 patients were thrombolysed with 42 confirmed as having had ischaemic strokes on subsequent MRI imaging. All patients were discussed with a stroke consultant before thrombolysis. Mean time from arrival to CT improved from 51 to 34.5 minutes, admission to stroke unit from 7hr53 to 4hr36 and to thrombolysis from 2hr18 to 1hr22. The number of thrombolysis complications decreased from 5 to 2. Since the changes, the SSNAP grade for stroke unit admission improved from C to A and specialist assessments from E to B.
Conclusion
The changes implemented following the May 2021 CQC inspection have had a positive impact on the care of thrombolysed stroke patients and overall SSNAP grades at RLI. Improvements are still required and the next steps include improving the efficiency of thrombolysis times and further improving SSNAP grades.

Abstract
The huge numbers of non-healthcare personnel (non-HCP) who get infected by corona virus disease 2019 (COVID-19) not only paralyze health care systems but also put health care personnel (HCP) at potential risk globally. Objective of the study was to compare the Healthcare personnel (HCP) and non-HCP COVID-19 cases. This prospective observational study was carried out in National Heart Foundation Hospital and Research Institute of Bangladesh from March 08, 2020 to July 20, 2020. During this study period all admitted non-HCP who subsequently was diagnosed as COVID-19 positive by rRT-PCR and HCP of this hospital, who experienced fever or respiratory symptoms or came in close contact with COVID-19 patients at home or their workplace and become COVID-19 positive, were included. Out of 320 infected patients, 181(56.6%) patients were non-HCP and 139(43.4%) were HCP. Non-HCP were older than HCP (Mean age: 52.95±13.82 years vs. 34.08±11.11 years; p=0.001). Non-HCP were predominantly male and HCP were predominantly female (73.5% vs. 41% & 26.5% vs. 59%; p=0.001). Non-HCP had more risk factors and co-morbidities than HCP (p=0.001). Typical symptoms of COVID-19 such as fever and cough were prevalent in HCP. More aggressive treatment was required for non-HCP. Non-HCP had more severe disease and higher case fatality rate (9.4% vs. 0.7%; p=0.001) than HCP. Disease severity (OR 0.03, 95% CI 0.01-0.15) and DM (OR 0.09, 95% CI 0.01-0.94) were the independent predictor of mortality. Non-HCP was older in age, predominantly male and had more co-morbidities than HCP. Typical symptoms of COVID-19 were prevalent in HCP. Non-HCP had more severe disease and higher case fatality rate than HCP.

Abstract
SummaryThe intrahepatic kinetics of 111indium-labelled platelets have been studied using dynamic gamma camera scintigraphy immediately following injection. Platelets labelled in saline with mIn-oxine or 111In-acetylacetonate underwent rapidly reversible hepatic sequestration, indicating that they were “activated”. Platelets labelled in plasma with 111In-tropolonate, however, did not display this phenomenon. On the assumption that plasma-labelled platelets display a normal initial bio-distribution, mean intrahepatic platelet transit time, as a factor of the transit time of 99m-Tc labelled red cells, was 1.45 ± SE 0.12 (n = 6), implying the normal presence of a small intrahepatic platelet pool. Unlike the liver, transit through the spleen was not sensitive to the labelling medium; thus the mean intrasplenic transit time of plasma-labelled platelets was 9.3 ± SE 0.7 min (n = 10), and of saline-labelled platelets 9.5 ± SE 0.3 min (n = 8).

The role of supplementary environmental surveillance to complement acute flaccid paralysis surveillance for wild poliovirus in Pakistan - 2011-2013. PLoS One 2017; 12:e0180608.

Abstract
Background More than 99% of poliovirus infections are non-paralytic and therefore, not detected by acute flaccid paralysis (AFP) surveillance. Environmental surveillance (ES) can detect circulating polioviruses from sewage without relying on clinical presentation. With extensive ES and continued circulation of polioviruses, Pakistan presents a unique opportunity to quantify the impact of ES as a supplement to AFP surveillance on overall completeness and timeliness of poliovirus detection. Methods Genetic, geographic and temporal data were obtained for all wild poliovirus (WPV) isolates detected in Pakistan from January 2011 through December 2013. We used viral genetics to assess gaps in AFP surveillance and ES as measured by detection of ‘orphan viruses’ (≥1.5% different in VP1 capsid nucleotide sequence). We compared preceding detection of closely related circulating isolates (≥99% identity) detected by AFP surveillance or ES to determine which surveillance system first detected circulation before the presentation of each polio case. Findings A total of 1,127 WPV isolates were detected by AFP surveillance and ES in Pakistan from 2011–2013. AFP surveillance and ES combined exhibited fewer gaps (i.e., % orphan viruses) in detection than AFP surveillance alone (3.3% vs. 7.7%, respectively). ES detected circulation before AFP surveillance in nearly 60% of polio cases (200 of 346). For polio cases reported from provinces conducting ES, ES detected circulation nearly four months sooner on average (117.6 days) than did AFP surveillance. Interpretation Our findings suggest ES in Pakistan is providing earlier, more sensitive detection of wild polioviruses than AFP surveillance alone. Overall, targeted ES through strategic selection of sites has important implications in the eradication endgame strategy.

Abstract
BACKGROUND AND AIMS vitamin D deficiency (25-hydroxyvitamin D) affects over one billion people worldwide. Vitamin D deficiency results in progression of osteoporosis as well as other conditions. Previous studies have shown high rates of vitamin D deficiency in Pakistan despite appreciable levels of sunshine. However, none have assessed vitamin D deficiency across all age groups, genders, incomes, and locations to guide future strategies. METHODS Questionnaire and blood sampling among 4830 randomly selected citizens. RESULTS High levels of deficiency among all age groups, genders, income levels, and locations. Amongst the selected citizens, 53.5% had vitamin D deficiency, 31.2% had insufficient vitamin D, and only 15.3% normal vitamin D. CONCLUSION High rates of vitamin D deficiency in Pakistan despite high levels of sunshine and previous Food Acts asking for food fortification with vitamin D. Public health strategies are needed to address high deficiency rates, including food fortification, i.e. nurture, alongside increasing exposure to sunlight, i.e. nature. This will involve all key stakeholder groups.

Abstract
BACKGROUND The environmental surveillance has proven to be a useful tool to identify poliovirus circulation in different countries and was started in Pakistan during July 2009 to support the acute flaccid paralysis (AFP) surveillance system. METHODS Sewage samples were collected from 27 environmental sampling (ENV) sites and processed for poliovirus isolation through 2-phase separation method. Poliovirus isolates were identified as Sabin-like or wild type through real-time polymerase chain reaction (PCR). Wild-type strains were subjected to VP1 gene sequencing and phylogenetic analysis performed using MEGA 5.0. RESULTS During 2011-2013, a total of 668 samples were collected from 4 provinces that resulted in 40% of samples positive for wild poliovirus type-1 (WPV-1). None of the samples were positive for WPV-3. The areas with high frequency of WPV-1 detection were Karachi-Gadap (69%), Peshawar (82%), and Rawalpindi (65%), whereas the samples from Quetta and Sukkur remained negative for WPV during 2013. Phylogenetic analysis revealed 3 major clusters with multiple poliovirus lineages circulating across different country areas as well as in bordering areas of Afghanistan. CONCLUSIONS Environmental surveillance in Pakistan has been proven to be a powerful tool to detect WPV circulation in the absence of poliomyelitis cases in many communities. Our findings emphasize the need to continue and expand such surveillance activities to other high-risk areas in the country.

Abstract
This article summarizes the status of environmental surveillance (ES) used by the Global Polio Eradication Initiative, provides the rationale for ES, gives examples of ES methods and findings, and summarizes how these data are used to achieve poliovirus eradication. ES complements clinical acute flaccid paralysis (AFP) surveillance for possible polio cases. ES detects poliovirus circulation in environmental sewage and is used to monitor transmission in communities. If detected, the genetic sequences of polioviruses isolated from ES are compared with those of isolates from clinical cases to evaluate the relationships among viruses. To evaluate poliovirus transmission, ES programs must be developed in a manner that is sensitive, with sufficiently frequent sampling, appropriate isolation methods, and specifically targeted sampling sites in locations at highest risk for poliovirus transmission. After poliovirus ceased to be detected in human cases, ES documented the absence of endemic WPV transmission and detected imported WPV. ES provides valuable information, particularly in high-density populations where AFP surveillance is of poor quality, persistent virus circulation is suspected, or frequent virus reintroduction is perceived. Given the benefits of ES, GPEI plans to continue and expand ES as part of its strategic plan and as a supplement to AFP surveillance.

Molecular characterization and phylogenetic relationship of wild type 1 poliovirus strains circulating across Pakistan and Afghanistan bordering areas during 2010-2012. PLoS One 2014; 9:e107697.

Abstract
Pakistan and Afghanistan share a long uncontrolled border with extensive population movement on both sides. Wild poliovirus transmission has never been interrupted in this block due to war against terrorism, poor public health infrastructure, misconceptions about polio vaccines and inadequate immunization activities. All these issues complicate the eradication operations and reinforce the complexity of wiping out poliomyelitis from this region. This study illustrates the origins and routes of cross-border wild poliovirus type 1 (WPV1) transmission during 2010-2012 between Pakistan and Afghanistan. Sequence analyses were conducted based on complete VP1 capsid protein sequences for WPV1 study strains to determine the origin of poliovirus genetic lineages and their evolutionary relationships. Phylogenetic tree was constructed from VP1 gene sequences applying Maximum Likelihood method using Kimura 2- parameter model in MEGA program v 5.0. A total of 72 (14.3%) out of 502 wild-type 1 polioviruses were found circulating in border areas of both countries during 2010-2012. Molecular phylogenetic analysis classified these strains in to two sub-genotypes with four clusters and 18 lineages. Genetic data confirmed that the most of WPV1 lineages (12; 66.6%) were transmitted from Pakistan to Afghanistan. However, the genetic diversity was significantly reduced during 2012 as most of the lineages were completely eliminated. In conclusion, Pakistan-Afghanistan block has emerged as a single poliovirus reservoir sharing the multiple poliovirus lineages due to uncontrolled movement of people across the borders between two countries. If it is neglected, it can jeopardize the extensive global efforts done so-far to eradicate the poliovirus infection. Our data will be helpful to devise the preventive strategies for effective control of wild poliovirus transmission in this region.

Abstract
Somatic mutations or deletions of TP53 and PTEN in ductal carcinoma in situ (DCIS) lesions have been implicated in progression to invasive ductal carcinomas. A recent molecular and mutational analysis of breast cancers revealed that inactivation of tumor suppressors, p53 and PTEN are strongly associated with triple negative breast cancer. In addition, these tumor suppressors play important roles in regulating self-renewal in normal and malignant stem cells. To investigate their role in breast carcinogenesis, we knocked down these genes in human mammary cells and in non-transformed MCF10A cells. p53 and PTEN knockdown synergized to activate pro-inflammatory IL6/Stat3/NF-κB signaling. This resulted in generation of highly metastatic EMT-like cancer stem cells (CSCs) resulting in tumors whose gene expression profile mimicked that found in basal/claudin-low molecular subtype within the triple negative breast tumors. Constitutive activation of this loop in transformed cells was dependent on proteolytic degradation of SOCS3 resulting in low levels of this protein in basal/claudin low cell lines and primary tumors. In non-transformed cells, transient activation of the IL6 inflammatory loop induced SOCS3 expression leading to pathway inactivation. In transformed cells, enforced expression of SOCS3 or interfering with IL6 pathway via IL6R blockade inhibited tumor growth and metastasis in mouse xenograft models. Furthermore, circulating tumor cells were significantly reduced in tumor bearing animals when treated with anti-IL6R antibodies. These studies uncover important connections between inflammation and carcinogenesis and suggest that blocking pro-inflammatory cytokines may be utilized as an attractive strategy to target triple negative breast tumors which currently lacks molecularly targeted therapies.

Autophagy triggered by magnolol derivative negatively regulates angiogenesis. Cell Death Dis 2013; 4:e889.

Abstract
Angiogenesis has a key role in the tumor progression and metastasis; targeting endothelial cell proliferation has emerged as a promising therapeutic strategy for the prevention of cancer. Previous studies have revealed a complex association between the process of angiogenesis and autophagy and its outcome on tumorigenesis. Autophagy, also known as type-II cell death, has been identified as an alternative way of cell killing in apoptotic-resistant cancer cells. However, its involvement in chemoresistance and tumor promotion is also well known. In this study, we used a derivate of natural product magnolol (Ery5), a potent autophagy inducer, to study the association between the autophagy and angiogenesis in both in vitro and in vivo model system. We found that the robust autophagy triggered by Ery5, inhibited angiogenesis and caused cell death independent of the apoptosis in human umbilical cord vein endothelial cells and PC-3 cells. Ery5 induced autophagy effectively inhibited cell proliferation, migration, invasion and tube formation. We further demonstrated that Ery5-mediated autophagy and subsequent inhibition of angiogenesis was reversed when autophagy was inhibited through 3-methyl adenine and knocking down of key autophagy proteins ATG7 and microtubule-associated protein light chain 3. While evaluating the negative regulation of autophagy on angiogenesis, it was interesting to find that angiogenic environment produced by the treatment of VEGF and CoCl2 remarkably downregulated the autophagy and autophagic cell death induced by Ery5. These studies, while disclosing the vital role of autophagy in the regulation of angiogenesis, also suggest that the potent modulators of autophagy can lead to the development of effective therapeutics in apoptosis-resistant cancer.

Abstract
Fluoroquinolone and macrolide antibiotics are generally considered as first-line drugs for the treatment of severe campylobacteriosis. This study was conducted to analyse the trend of erythromycin and ofloxacin resistance among Campylobacter spp. isolated from stool specimens over a period of 15 years (1992-2007) at The Aga Khan University clinical laboratory in Karachi, Pakistan. A total of 83 396 stool specimens were processed, with a 14% isolation rate for enteric pathogens. The isolation rate of Campylobacter spp. was low during 1992-93 (6%-13%), peaked in 1996 (46%), then ranged from 20% to 40%. We report a rising trend in ofloxacin resistance, re-emergence of erythromycin resistance and indications of co-resistance to both drugs in clinical isolates of Campylobacter spp.

Abstract
This retrospective study of 9,980 women who delivered at the James Paget Hospital, Norfolk, UK, over 5 years, aimed to primarily determine whether the incidence of hyperemesis gravidarum (HG) is higher in the presence of a female fetus. The results showed that more women with HG had a female fetus compared with women without HG. Also found was that heavy ketonuria was more prevalent in women with a female fetus compared with women with a male fetus, and the mean number of admissions per woman was also higher in women with a female fetus compared with women with a male fetus. It can be concluded that women presenting with HG are more likely to have a female fetus and that women with HG and a female fetus tend to a higher level of ketonuria and an increased number of hospital admissions.

Abstract
Radioactivity is a part of the natural environment. The presence of natural radioactivity in sand and other building materials results in internal and external exposure to the general public. Therefore, it is desirable to determine the concentration of naturally occurring radionuclides, namely (232)Th, (226)Ra and (40)K in sand, bricks and cement which are commonly used as building materials in Pakistan. In this context, sand samples were collected from 18 different locations covering an area of ∼1000 km(2) along the banks of river Indus (Ghazi to Jabba) and river Kabul (Nowshera to Kund) in the northern part of Pakistan, whereas bricks and cement samples were collected from local suppliers of the studied area. In order to measure the specific activities in these samples, a P-type coaxial high-purity germanium-based gamma-ray spectrometer was used. In sand samples, the average specific activities of (226)Ra, (232)Th, and (40)K were found to be 30.5±11.4, 53.2±19.5 and 531±49 Bq kg(-1), whereas in brick samples, specific activities of 30±14, 41±21 and 525±183 Bq kg(-1) were observed, respectively. In cement samples, measured specific activity values were 21±5, 14±3 and 231±30 Bq kg(-1), respectively. Radium equivalent activities were calculated and found to be 143.8±38.6, 124±49.8 and 56.69±7 Bq kg(-1) for sand, brick and cement samples, respectively. The annual mean effective dose for the studied sand samples was found to be 0.40 mSv. External and internal hazard indices were less than unity for all the studied samples. The present results have been compared with those reported in the literature.

Abstract
OBJECTIVE To investigate the impact of duration of untreated psychosis on emotion recognition in patients with first-episode psychosis. METHODS A sample of 60 patients with schizophrenia, schizoaffective and substance-induced psychoses were selected from psychiatric inpatients and outpatients of 3 hospitals in Lahore and 1 in Faisalabad, Pakistan. Patients were divided into short (n = 28) and long (n = 32) duration of untreated psychosis groups, according to whether they had had symptoms for < 80 or ≥ 80 weeks, respectively. Emotion recognition ability was assessed with the help of the Urdu version of a computerised experimental FEEL (Facially Expressed Emotion Labeling) test using 6 basic emotional expressions that appeared on a computer screen followed by possible responses. RESULTS Patients with prolonged durations of untreated psychosis showed poorer performance in recognition of facial expressions of emotion than those with short durations of untreated psychosis. This was apparent in general and especially for expressions of anger, surprise, and sadness. First-episode psychosis patients showed higher accuracy rates for recognising positive as opposed to negative emotions. The duration of untreated psychosis correlated positively with positive symptoms of psychosis. Symptom distribution differed across categories of psychosis, but there were similarities in patients with schizophrenia and schizoaffective disorders. CONCLUSIONS These findings support recourse to early detection and intervention strategies in psychosis and provide valuable information on how first-episode psychosis patients behave in complex emotional and social situations.

Abstract
Female sexual dysfunction (FSD) incorporates various sexual disorders including hypoactive sexual desire disorder, sexual arousal disorder, orgasmic and sexual pain disorders. Although many strategies have been formulated for the treatment of male sexual problems, FSD remains an area that warrants further research and trial studies to identify the most efficacious treatment options. Research has highlighted numerous pharmacological interventions that have been trialled and found to exhibit positive effects. These include hormonal therapies, prostaglandins, dopaminergic agonists, phosphodiesterase type-5 (PDE-5) inhibitors and melanocortin agonists.

Abstract
ABSTRACT A growing number of jurisdictions now request economic data in support of their decision-making procedures for the pricing and/or reimbursement of health technologies. Because more jurisdictions request economic data, the burden on study sponsors and researchers increases. There are many reasons why the cost-effectiveness of health technologies might vary from place to place. Therefore, this report of an ISPOR Good Practices Task Force reviews what national guidelines for economic evaluation say about transferability, discusses which elements of data could potentially vary from place to place, and recommends good research practices for dealing with aspects of transferability, including strategies based on the analysis of individual patient data and based on decision-analytic modeling.

Abstract
OBJECTIVE Clinical evidence supports the use of cardiac resynchronization therapy (CRT) in advanced heart failure, but its cost-effectiveness is still unclear. This analysis assessed the economic and health consequences in the UK of implanting a CRT in patients with NYHA class III-IV heart failure. METHODS A discrete event simulation of heart failure was used to compare the course over 5 years of 1000 identical pairs of patients -- one receiving both CRT and optimum pharmacologic treatment (OPT), the other OPT alone. All inputs were obtained from the data collected in the CArdiac REsynchronization in Heart Failure (CARE-HF) trial and a hospital in the UK. Direct medical costs (in 2004 pound) from the perspective of the National Health Service were considered. Both costs and benefits were discounted at 3.5%. Sensitivity analyses addressed all model inputs and multivariate analyses were performed by varying key parameters simultaneously. RESULTS The model predicted 471 deaths and 2263 hospitalizations over 5 years with OPT alone and 348 deaths and 1764 hospitalizations with CRT, equivalent to a 26% reduction in mortality and 22% in hospitalizations, at a discounted cost of pound 11,423 per patient with CRT vs. pound 4,900 with OPT alone. CRT was predicted to increase quality-adjusted survival by 0.43 QALYs per patient, resulting in an incremental cost-effectiveness ratio of pound 15,247 per QALY gained (range: pound 12,531- pound 23,184). Sensitivity analyses revealed that this outcome was most sensitive to time horizon and cost of implantation. CONCLUSION Based on these 5-year analyses, CRT is expected to yield substantial health benefits at a reasonable cost.

Abstract
OBJECTIVE To determine the point prevalence of benzodiazepine prescriptions for inpatients at a tertiary care university hospital in Pakistan and to correlate it with prescription patterns of various specialties, indications and demographic variables of the patients. METHODS This 24-hours point prevalence study was done at The Aga Khan University Hospital, Karachi. By convenient random sampling, 208 inpatients were interviewed. Patients' files were also studied to record the drugs administered. Data was entered into questionnaires and analyzed by SPSS 10.0. RESULTS The point prevalence of the benzodiazepines was 21.2%. It was higher among males than females and among surgical than non-surgical patients. Midazolam was the most commonly used benzodiazepine, followed by Alprazolam and Lorazepam. Pre-anesthesia and psychiatric symptoms were the two most common indications. Oral route was used in 84% patients for drug administration and mean Valium equivalent dosage was 4.86 mg/day. Mean length of prescription was 3 days. Longer duration of hospitalization was a significant predictor of the requirement of benzodiazepine prescription (p-value = 0.020). CONCLUSION Prescription pattern of benzodiazepines at a tertiary care university hospital is similar to that reported in the developed countries through monitoring at various levels by physicians, clinical pharmacist and nursing staff. Data regarding the prescription pattern of benzodiazepines is scarce, and it needs to be expanded to formulate clear guidelines regarding their prescription.

Abstract
Coronary angiographic characteristics of fifty patients with type 2 diabetes mellitus and coronary artery disease (CAD) were compared with fifty non diabetic patients with CAD. Type 2 diabetic patients undergoing clinically indicated elective coronary angiography were individually matched with fifty non diabetic coronary artery disease patients for age, sex and major risk factors. No significant difference was present between the mean age, presenting complains and other coronary risk factors between the two groups. Severity and extent of coronary artery involvement was assessed by a coronary artery score (CAS) using the segmental distribution method for coronary artery lesions and morphometric analysis of atherosclerotic lesion was done. Type 2 diabetic patients had a higher CAS (11.74+/-5.04 vs 8.72+/-4.87; P<0.001) as compared to the non-diabetic patients. Multivessel disease were more prevalent in both the groups (82% vs 68%; P>0.05) but diabetic patients had significantly higher number of triple vessel disease (58% vs. 38%; P<0.001). Normal coronary arteries and single vessel disease were more prevalent in non-diabetic patients (32% vs. 18%; P<0.05). As compared to non-diabetic group diabetic patients had a higher total number of diseased vessels (78.66% vs. 68%; P<0.01), a higher lesion per patient ratio (3.94+/-1.80 vs 3+/-1.67:P<0.001) and more proximal lesions (40.83% vs. 34.70%; P>.05) though not statistically significant. Morphometric analysis of coronary artery lesions revealed that diabetic patients had significantly higher number of multiple irregularity lesions (24.37% vs. 15.33%; P<0.01) and lesions were more obstructive (lesion involving 70-90% of coronary lumen: 70.53.% vs. 57.33%; P<0.05). Though there was no significant difference between the systolic left ventricular function between the two groups but significant higher regional wall motion abnormality was found more in diabetic patients (76%vs 62%; P<0.01). So type 2 diabetic patients had more severe and extensive atherosclerotic lesion in their coronary arteries than the matched non diabetic control on coronary angiography suggesting an independent effect of diabetic mellitus on atherosclerotic process specially in our population.

Abstract
This study examined the clinical workload, outcome and direct costs of managing women with sexual dysfunction in an NHS clinic in the UK. A retrospective analysis of a 3-month period showed that of 47 referrals to the clinic, 38 undertook treatment. The therapists' assessments suggested that over 80% of patients improved on treatment. The average cost per patient was pound 472 (compared to pound 335 per annum for erectile dysfunction, which included physician's and drug costs). The average cost by type of practitioner was pound 278 (psychologist), pound 322 (physician), pound 532 (physician and psychologist) and pound 597 (sex therapist). Patients required between 1 and 51 treatment sessions, which were mainly restricted to psychological therapy. Female sexual dysfunction (FSD) represents a significant economic burden to the NHS. Further research on the potential role and cost effectiveness of pharmacological agents for FSD is warranted.

Coronary artery disease in young adults - angiographic profile. Mymensingh Med J 2004; 13:11-5. [PMID: 14747777] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 04/28/2023]
Abstract
Angiographic profile of fifty young patients of coronary artery disease aged 40 or under were analysed and compared with those of fifty older patients. Mean age of younger and older group was 36.34 (range 28 to 40 years) and 55.28 (44-74 years) years respectively and most of the patients were male in both the group (92 Vs 94%). Older patients were more diabetes (40 Vs 24%) and hypertensive (38 Vs 60%) but the younger patients had more family history of premature coronary artery disease (50% Vs 24%). The incidence of smoking and dyslipidemia did not vary between the two groups. Older patients had more history of myocardial infarction (69 Vs 58%) but angina were more in young patients (42 Vs 31%). Coronary angiography revealed more number of multivessel disease in older patients (74 Vs 54%) but the younger patients had more normal coronary arteries and single vessel disease (46 vs 26%). Coronary athesclerosis was also extensive in older patients as revealed by the higher coronary score, more involvement of coronary segments, more number of diseased and diffusely involved coronary vessel in older patients. Older patients needed more revasalarization process (74 Vs 60%), more coronary bypass surgery (40 Vs 24%) and had more inoperable vessels (16% Vs 4%) than the younger patients. So the younger patients having less extensive coronary artery athesclerosis with better prognostic probability should be evaluated angiographically for further definitive management in the from of revascularization.

Abstract
Hundred patients of Type 2 diabetes mellitus with coronary artery disease undergoing diagnostic coronary angiography were studied to determine the relation between the severity and duration of diabetes mellitus and the severity of coronary artery disease. A coronary scoring system using segmental distribution method was used to determine the severity of coronary artery disease and severity of diabetes was assessed by the level of fasting blood glucose within 48 hours of the procedure and also considering the types of treatment received for diabetes mellitus. No significant correlation was demonstrated between the severity of coronary artery disease and the severity (r =.089602; P>0.1) nor the duration (r =0.07865; P> 0.1) of diabetes mellitus on univariate analysis. So the Type 2 diabetic patients had an increased incidence of atherosclerosis in their coronary angiograms did not reflect an angiographically evident progressive coronary artery disease and results of this study suggest that the progress of large vessel coronary athesclerotic disease in diabetes mellitus of adult onset takes place independently of the progress of diabetes mellitus itself.

Abstract
Fifty consecutive younger patients (< or = 40 years) with coronary artery disease, who underwent coronary angiography in National Institute of Cardiovascular Diseases were evaluated clinically and coronary risk factors were analyzed and compared with those of fifty older patients with coronary artery disease. Mean age of younger and older patients were 37.31 and 54.58 years respectively and myocardial infarction was the most common presenting complain in both the groups. Smoking and family history of premature coronary artery disease were more common in younger patients but the older patients were more diabetic and hypertensive. Central obesity and dyslipidemia did not vary between the two groups. Fifty percent of younger patients had one or two modifiable risk factors where sixty four percent of older patients had three or more modifiable risk factors. Forty four percent younger patients had hypercholesterolemia but a majority of patients had either isolated hypertriglyciredemia or decrease high density lipoprotein cholesterol or both with normal total cholesterol level but the total cholesterol and high density lipoprotein cholesterol index were more than 4.5. Younger patients had more number of normal coronary or single vessel diseases but older group had more number of triple vessel diseases. So the higher incidence of non-insulin dependent diabetes mellitus with central obesity suggesting insulin resistance along with unique profile of dyslipidemia, higher incidence of smoking and familial predisposition of premature coronary artery disease may be responsible for higher incidence of coronary artery disease at a premature younger age in this population.

Abstract
BACKGROUND Left ventricular hypertrophy is a heterogeneous disorder with distinct morphologies. Changes in wall thickness, left ventricular chamber diameter, and mass alter systolic wall stress of the left ventricle and may influence ischemic threshold. Thus, the goal of this study was to investigate the effect of the different patterns of left ventricular hypertrophy on the accuracy of dobutamine-atropine stress echocardiography. METHODS AND RESULTS Three-hundred eighty-six patients underwent multistage dobutamine-atropine stress echocardiography and diagnostic angiography. Echocardiograms were measured for mean and relative wall thicknesses, chamber size, left ventricular mass, and end-systolic wall stress. The patterns of ventricular hypertrophy were concentric hypertrophy (increased wall thickness and mass), eccentric hypertrophy (normal wall thickness and increased mass), and concentric remodeling (increased wall thickness and normal mass). The overall sensitivity, specificity, and accuracy of dobutamine-atropine stress echocardiography for the detection of coronary artery disease were 85%, 87%, and 86%, respectively. Increased left ventricular mass index alone did not affect accuracy. Sensitivity was markedly reduced (36%) only in those with concentric remodeling. The univariate predictors of false-negative studies were single-vessel left circumflex disease, increased wall thickness, small chamber size, hyperdynamic ejection fraction, and left ventricular concentric remodeling. Multivariate predictors were concentric remodeling (P<0.0001; odds ratio, 13.5), left ventricular ejection fraction >2 SD above normal (P<0.0001), and single-vessel left circumflex disease (P<0.0007; odds ratio, 7.6). Sensitivity was excellent in patients with small ventricles and normal wall thickness and in those with normal or large chambers regardless of wall thickness. CONCLUSIONS Dobutamine-atropine stress echocardiography is an accurate test in most patients with left ventricular hypertrophy, but it is insensitive in the small subset with concentric remodeling.
