RESUMO

Olive family (Oleaceae) contains several species among which Olea europaea L. is mostly used for production of olive oils. Various parts of olive tree are rich source of diverse bioactive compounds such as Apigenin, elenolic acid, Hydroxytyrosol, Ligstroside, Oleoside, Oleuropein, Oleuropein aglycone, Tyrosol, etc. Among these, oleuropein, a secoiridoid is predominantly found in olive leaves and young olive fruits of different species of Oleaceae family. Scientists have adopted numerous extraction methods (conventional & latest) to increase the yield of oleuropein. Among these techniques, maceration, soxhlet, microwave-assisted, ultrasonication, and supercritical fluid methods are most commonly employed for extraction of oleuropein. Evidently, this review emphasizes on various in-vitro and in-vivo studies focusing on nutraceutical properties of oleuropein. Available literature highlights the pharmaceutical potential of oleuropein against various diseases such as obesity, diabetes, cardiovascular complications, neurodegenerative diseases, cancer, inflammation, microbial infections, and oxidation. This review will benefit the scientific community as it narrates comprehensive literature regarding absorption, metabolism, bioavailability, extraction techniques, and nutraceutical perspectives associated with oleuropein.

RESUMO

OBJECTIVE: To report outcomes following open or endovascular treatment of true hepatic and coeliac artery aneurysms at a single referral centre. METHODS: This was a retrospective cohort study of consecutive patients treated for true hepatic and coeliac artery aneurysms between May 2002 and December 2021. Outcome measures included complications, graft patency, and survival rate. RESULTS: Overall, 84 patients were included with a median age of 63 years (interquartile range 55, 79). The majority (76%) of the patients were men. Frequent comorbidities included a history of tobacco (69%), hypertension (65%), hyperlipidaemia (32%), and diabetes (15%). Multiple synchronous aneurysms were detected in 22 patients (26%). There were 33 (39%) symptomatic aneurysms (abdominal pain without rupture [n = 18], rupture [n = 10], and sepsis [n = 5]). Seventeen patients (20%) had mycotic aetiology. Fifty patients (60%) underwent endovascular treatment with either covered stent placement (n = 29) or coil embolisation (n = 21), and 34 patients (40%) were treated with open surgery using allogenic iliac artery (n = 15), autologous saphenous vein (n = 15), GoreTex graft (n = 2), or ligation (n = 2). The complication rate was 32% in the open group and 18% in the endovascular group (p = .048). The overall 90 day post-operative mortality rate was 1.2%, five year primary patency was 90.0%, five year survival rate was 81.2%, and mean follow up was 6.9 ± 4.2 years. CONCLUSION: Endovascular treatment is the preferred approach whenever technically possible. Despite higher post-operative morbidity, an open approach with vascular reconstruction using autologous or allogenic vascular grafts yields acceptable long term results.

RESUMO

BACKGROUND: Accumulating evidence suggests that refractive stabilization occurs rapidly following small incision cataract surgery. Nonetheless, many guidelines still suggest waiting four to 6 weeks before prescribing corrective lenses. This study was undertaken to supplement the existing literature regarding refractive stabilization, and evaluate multiple contributing factors that could dissuade clinicians from confidently correcting refractive error in the early post-operative course following routine cataract surgeries. METHODS: Adult patients undergoing phacoemulsification cataract surgery with uncomplicated surgeries and post-surgical courses at the Calgary Ophthalmology Centre (Calgary, Alberta, Canada) were included in this prospective observational case series. Exclusion criteria included known corneal dystrophies, infectious keratitis, complicated surgery or toric/multifocal IOLs. Data was collected at weekly intervals for a total of 6 weeks. Collected data included autorefraction, visual acuity, corneal pachymetry, and effective lens position. RESULTS: One hundred six eyes of 104 patients were included in this study. Post-operative sphere, cylinder and spherical equivalent were not significantly different at any post-operative week compared with week six, and 80-86% of patients were within 0.5D of last follow-up spherical equivalent at any week. The secondary outcomes of central corneal thickness, effective lens position and visual acuity did, however, exhibit significant differences between early post-operative weeks and last follow-up values. CONCLUSIONS: These data suggest that refractive error can be effectively measured and corrected as early as one-week post-operatively in the majority of patients, though other measures of post-operative stability including central corneal thickness, effective lens position and visual acuity can require up to 4 weeks to stabilize. Thus a conservative and pragmatic approach may be to wait until 4 weeks post-operatively prior to obtaining refractive correction following uncomplicated phacoemulsification cataract surgery.

RESUMO

Background and Objectives: Cardioplegia is one of the most significant components used to protect the myocardium during cardiac surgery. There is a paucity of evidence regarding the utilization of whole-blood Del Nido cardioplegia (WB-DNC) on clinical outcomes in coronary artery bypass grafting (CABG). The purpose of this retrospective cross-sectional study is to compare the effectiveness of diluted (blood to crystalloid; 1:4) Del Nido cardioplegia (DNC) with WB-DNC in patients who underwent elective CABG in a tertiary care hospital in Lahore-Pakistan. Materials and Methods: This was a retrospective descriptive study conducted at the Department of Cardiovascular Surgery, King Edward Medical University, Lahore. The medical database of all consecutive patients admitted from January 2018 to March 2020 and who fulfilled the inclusion criteria were reviewed. Results: Out of 471 patients admitted during the study period, 450 underwent various elective cardiac surgeries. Out of 450, 321 patients (71.33%) were operated on for CABG. Only 234/321 (72.89%) CABG patients fulfilled our inclusion criteria; 120 (51.28%) patients received WB-DNC, while 114 (48.71%) patients were administered with DNC. The former group presented with better clinical outcomes compared with the latter in terms of lesser requirements of inotropic support, low degree of hemodilution, shorter in-hospital stay, improved renal function, and cost-effectiveness. Peak values of serum Troponin-T (Trop-T), creatine kinase-myocardial band (CK-MB) release, and activated clotting time (ACT) were also lower in the WB-DNC group compared with the DNC group. Conclusions: The WB-DNC conferred better myocardial protection, improved early clinical outcomes, and also proved to be economical for patients undergoing elective CABG compared with classical crystalloid cardioplegia solution.

RESUMO

BACKGROUND: Contemporary practice for superior mesenteric/portal vein (SMV-PV) reconstruction during pancreatectomy with vein resection involves biological (autograft, allograft, xenograft) or synthetic grafts as a conduit or patch. The aim of this study was to systematically review the safety and feasibility of the different grafts used for SMV-PV reconstruction. METHODS: A systematic search was performed in PubMed and Embase according to the PRISMA guidelines (January 2000-March 2020). Studies reporting on ≥ 5 patients undergoing reconstruction of the SMV-PV with grafts during pancreatectomy were included. Primary outcome was rate of graft thrombosis. RESULTS: Thirty-four studies with 603 patients were included. Four graft types were identified (autologous vein, autologous parietal peritoneum/falciform ligament, allogeneic cadaveric vein/artery, synthetic grafts). Early and overall graft thrombosis rate was 7.5% and 22.2% for synthetic graft, 5.6% and 11.7% for autologous vein graft, 6.7% and 8.9% for autologous parietal peritoneum/falciform ligament, and 2.5% and 6.2% for allograft. Donor site complications were reported for harvesting of the femoral, saphenous, and external iliac vein. No cases of graft infection were reported for synthetic grafts. CONCLUSION: In selected patients, autologous, allogenic or synthetic grafts for SMV-PV reconstruction are safe and feasible. Synthetic grafts seems to have a higher incidence of graft thrombosis.

RESUMO

PURPOSE: To evaluate the long-term outcomes of percutaneous transhepatic stent placement for portal vein (PV) stenosis after liver transplantation (LT) and hepato-pancreato-biliary (HPB) surgery. METHODS: Retrospective study of 455 patients who underwent LT and 522 patients who underwent resection of the pancreatic head between June 2011 and February 2016. Technical success, clinical success, patency, and complications were evaluated for both groups. RESULTS: A total of 23 patients were confirmed to have postoperative PV stenosis and were treated with percutaneous transhepatic PV stent placement. The technical success rate was 100%, the clinical success rate was 80%, and the long-term stent patency was 91.3% for the entire study population. Two procedure-related hemorrhages and two early stent thromboses occurred in the HPB group while no complications occurred in the LT group. A literature review of selected studies reporting PV stent placement for the treatment of PV stenosis after HPB surgery and LT showed a technical success rate of 78-100%, a clinical success rate of 72-100%, and a long-term patency of 57-100%, whereas the procedure-related complication rate varied from 0-33.3%. CONCLUSIONS: Percutaneous transhepatic PV stent is a safe and effective treatment for postoperative PV stenosis/occlusion in patients undergoing LT regardless of symptoms. Due to increased risk of complications, the indication for percutaneous PV stent placement after HPB surgery should be limited to patients with clinical symptoms after an individual assessment.

RESUMO

OBJECTIVE: To determine the utilisation of intravenous tissue plasminogen activator at a certain dose for ischaemic stroke thrombolysis and to compare the outcomes with those of a different dosage mentioned in literature. METHODS: The retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised medical records from January, 2007, to October, 2016, of all patients having received intravenous tissue plasminogen activator for ischaemic stroke thrombolysis. Primary safety outcome variables included symptomatic intracerebral haemorrhage after the start of treatment (0.6mg/kg) and death within three months as per the modified Rankin scale 6. Secondary efficacy outcome variable was functional independence as per modified Rankin scale 0-2 at three months. The outcomes were compared with those mentioned in literature with a dose of 0. 9mg/kg. RESULTS: Of the 79 patients, 52 (66%) were male and 27 (34 %) were female. Median pre-treatment tissue plasminogen activator score was 12 (interquartile range: 8-15). Overall utilisation of t-PA remained at 1.7%. Symptomatic intracerebral haemorrhage was not seen in our cohort while it was seen in 107 (1.7%) patients at the higher dose. Using another definition, it was seen in 3 (3.8%) patients versus 468 (7.3%) patients at the higher dose. Functional independence was seen in 40 (50.6%) patients at three months compared to 3362 (54.8%) patients at the higher dose. CONCLUSIONS: Low-dose intravenous thrombolytic therapy for ischaemic stroke patients was found to be safe and efficacious, and yielded comparable results with those obtained at a higher dose..

RESUMO

PURPOSE: The incidence of intraoperative arterial injury during pancreatectomy is not well described. This study aims to evaluate the incidence, management, and outcome of arterial injuries during pancreatectomy. METHODS: This is a retrospective study of 1535 consecutive patients undergoing pancreatectomy between 2006 and 2016 at Oslo University Hospital. The type of arterial injury and potential contributing factors were analyzed. Short-term outcomes were compared between patients with arterial injury and patients undergoing a planned arterial resection due to tumor involvement. RESULTS: Arterial injury was diagnosed in 14 patients (incidence 0.91%), while planned arterial resection was performed in 22 patients. The injuries were located in the superior mesenteric artery (n = 5), right hepatic artery (n = 5), common hepatic artery (n = 2), left hepatic artery (n = 1), and celiac trunk (n = 2). The artery was reconstructed in all except one patient. In 11 patients with injury, peripancreatic inflammation, aberrant arterial anatomy, close relationship between tumor and injured artery, or a combination of the three were found. Median estimated blood loss was 1100 ml in both groups. Rate of severe complications (≥ Clavien grade IIIa), comprehensive complication index, and 90-day mortality for patients with intraoperative arterial injury vs planned arterial resection were 43 vs 45% (p = 0.879), median 35.9 vs 21.8 (p = 0.287), and 14.3 vs 4.5% (p = 0.551), respectively. CONCLUSION: Arterial injury during pancreatectomy is an infrequent and manageable complication. Early recognition and primary repair in order to restore arterial liver perfusion may improve outcome. However, the morbidity is high and comparable to patients undergoing a planned arterial resection.

RESUMO

OBJECTIVE: To assess the time in therapeutic range in patients on warfarin anti-coagulation therapy. METHODS: The retrospective chart review was conducted at Aga Khan University Hospital, Karachi, and comprised data of patients having undergone anti-coagulation with warfarin from January 2013 to April 2015. To determine the mean time in therapeutic range, Rosendaal method was used. Association of time in therapeutic range with the composite outcome, bleeding and thromboembolic events was also assessed. Percentage of patients with time in therapeutic range <60% was calculated. RESULTS: There were 92 patients whose median time in therapeutic range was 34.9% (interquartile range: 20.0- 55.7). Overall, 71(77.2%) patients had time in therapeutic range below 60% which had statistically significant correlation with the composite outcome (p<0.05). Number of comorbids was significant in predicting time in therapeutic range and patients with time in therapeutic range< 60% (p<0.05). CONCLUSION: Subjects had poor anti-coagulation quality. It might be prudent to move towards novel oral anticoagulant drugsas the first choice for therapeutic anti-coagulation.

RESUMO

Plasmonic pixels have been shown to offer numerous advantages over pigment-based color filters used in modern commercial liquid crystal (LC) displays. However, wideband dynamic tunability across the visible spectrum remains challenging. We experimentally demonstrate transmissive electrically tunable LC-nanohole pixels operating across the visible spectrum with unpolarized input light. An ultrathin Al nanohole electrode is designed to exhibit a polarized spectral response based on surface plasmon resonances. An output analyzer in combination with a nematic LC layer enables pixel color to be electronically controlled through an applied voltage across the device, where LC reorientation leads to tunable mixing of the relative contributions from the plasmonic color input. The nanostructured Al layer, acting as a combined electrode, polarizer, and functional color filter, is highly promising for electro-optic display applications.

RESUMO

OBJECTIVES: This study aimed to determine the normal vasculature indices of the endometrium and to correlate them with those in various physiological states. METHODS: Women undergoing ultrasound at the Feto-Maternal Center, Qatar in 2020-2021 as part of their gynecologic evaluation were enrolled into the study. They were divided into those with normal menses and no additional pathology, those following spontaneous miscarriage, postpartum and menopausal. Three-dimensional (3D) evaluation of the endometrial vasculature was done and the parameters quantified included vascularization index (VI), flow index (FI), vascularization flow index (VFI), endometrial thickness, endometrial volume and uterine volume. JASP, an open-source statistical analysis software, was used for analysis and an independent t-test to compare the vascularity indices. A multivariate regression analysis was also done to look at the factors affecting the endometrial vascular indices within the luteal phase. RESULTS: A total of 461 women were studied: 122 in the follicular phase, 199 in the luteal phase, 90 after a spontaneous miscarriage, 29 postpartum, and 16 menopausal. The vascularity indices were highest after miscarriage and lowest postnatally. There were no significant effects of age, gravida, para, or abortions on VI and VFI. However, there was a significant positive effect of age on FI (P = 0.019) There was a significant increase in endometrial volume and thickness in the luteal phase as compared to follicular phase (P < 0.01), but there was no difference in the vascularity indices. The uterine and endometrial volume in the postnatal group were nearly double that of the luteal group (P value <0.01 and 0.014, respectively). There was a significant decrease in flow index in the postnatal group compared to the luteal group (P < 0.01), suggesting low flow intensity in the postnatal group. CONCLUSIONS: Endometrial vascular indices measured using 3D Doppler can be used to determine normal vascular indices and vary with physiological states such as after miscarriages, postnatally and in the menopausal states.

RESUMO

Echinococcus multilocularis, the fox dwarf tapeworm, causes alveolar echinococcosis (AE), a critical and life-threatening condition. A radical surgical approach represents the only curative option. In this case study, we present a 37-year-old man diagnosed with extensive hepatic AE requiring ex-situ extended right-sided liver resection including the caudate lobe and retro-hepatic vena cava. The left liver segments were auto-transplanted with reconstruction of the left hepatic vein and an inferior vena cava graft. In the post-operative course, the patient developed a bile leak, which was successfully managed with endoscopic stent intervention. He was discharged after a three-week hospitalization. Medical treatment with albendazole was initiated preoperatively and continued postoperatively.

RESUMO

BACKGROUND: The prevalence and severity of many etiologies of glaucoma increase with age, often requiring surgery later in life. Surgery in the most aged demographic, however, poses multiple unique physiologic and psychosocial challenges with variable outcomes. In this study, we evaluate the efficacy and safety of gonioscopy-assisted transluminal trabeculotomy (GATT) in an advanced-age population (>85 years of age). METHODS: This is a single-centre retrospective cohort study of consecutive patients who underwent GATT at or above 85 years of age. This included patients with GATT of any circumferential extent (90°-360°) with or without concurrent phacoemulsification cataract surgery. The primary outcome measure was proportion of successful surgeries at 1 year by the "complete success" criteria (intraocular pressure [IOP] <17 mm Hg on no medications 3 months after surgery with no additional interventions). Secondary outcomes included proportion of successful surgeries by alternative criteria, cross-sectional analyses of IOPs and medication use, and analyses of postoperative complications and interventions. RESULTS: Forty eyes of 31 patients were included in the study. Mean baseline IOP was 16.75 ± 7.33 mm Hg on 1.60 ± 1.43 classes of medication. At 1 year, the cumulative survival by Kaplan-Meier analysis was 46.6%. There was a statistically significant reduction in IOP at all postoperative time points to a mean of 11.78 ± 3.07 mm Hg at the last follow-up. There were postoperative complications in 18 eyes, with hyphema and corneal edema accounting for the majority. CONCLUSIONS: This study provides evidence that GATT is a safe and effective intervention in advanced-age glaucoma populations.

RESUMO

AIMS: Psoriasis is an immune-mediated skin disease characterized by keratinocytes hyperproliferation, abnormal differentiation and inflammation. Therefore, this study aimed to investigate in-vitro and in-vivo anti-inflammatory and anti-proliferative activity to evaluate anti-psoriatic potential of apigenin. MAIN METHODS: For in-vivo study, 5 % imiquimod cream was used to induce psoriasis-like skin inflammation in BALB/c mice to mimic human psoriatic conditions. PASI score, CosCam score, histopathology, immunohistochemistry, qRT-PCR, and ELISA were done to evaluate the anti-psoriatic potential of topically applied apigenin. For in-vitro studies, LPS-induced inflammation in RAW 264.7 was done, and qRT-PCR, ELISA, and immunofluorescence were conducted to evaluate the anti-inflammatory activity of apigenin. Migration and cell doubling assay in HaCaT cells were performed to assess the anti-proliferative effect of apigenin. Acute dermal toxicity profile of apigenin has also been done as per OECD guidelines. KEY FINDINGS: Results showed that apigenin significantly reduce the PASI and CosCam scores, ameliorate the deteriorating histopathology, and effectively downregulated the expression of CCR6, IL-17A, and NF-κB. Apigenin effectively downregulated the expression and secretion of pro-inflammatory cytokines through IL-23/IL-17/IL-22 axis. Apigenin suppressed nuclear translocation of NF-κB in LPS-induced RAW 264.7 cells. Cell migration and cell doubling assay in HaCaT cells showing the anti-proliferative potential of apigenin and it was found safe in acute dermal toxicity study. SIGNIFICANCE: Apigenin was found effective against psoriasis in both in-vitro and in-vivo models suggesting apigenin as a potential candidate for the development of anti-psoriatic agent.

RESUMO

INTRODUCTION: The size of the coronary artery influences the effective outcome of therapeutic measures like coronary artery bypass graft (CABG) surgery, percutaneous coronary interventions (PCI), and diagnosis of coronary artery disease. Patients' age, gender, BMI, anatomical variations, and increased left ventricular size all have an effect on coronary artery parameters. OBJECTIVE: This study aims to compare the average size of the coronary arteries of the Pakistani population in both sexes for manifestation of coronary artery disease. METHODOLOGY: For the analysis of the coronary arteries, 100 patients of both sexes, male and female, were taken. X-ray angiography was performed for two-dimensional images of coronary arteries. For diameter measurement, images were visualized on quantitative coronary angiography (QCA) in different views (caudal and cranial views). The diameters of the left main coronary artery (left main stem/LMS), left anterior descending (LAD), left circumflex (LCx), and right coronary artery (RCA) were measured on angiograms. Data about the dimensions of the coronary artery was gathered through quantitative angiography. Data analysis was done through SPSS version 26 (IBM Corp., Armonk, NY). RESULTS:  There is a notable distinction in the average diameters among the proximal LAD (3.12), mid-LAD (2.40), and distal LAD (1.29). A statistically significant difference is evident among mid-LCx, distal LCx, and proximal LCx (p-value < 0.001). Likewise, the average diameter of the distal RCA (1.89) was smaller when compared to the mid-RCA (3.19) and proximal RCA (3.78). However, there was no significant difference in the average diameter among mid-LMS, distal LMS, and proximal LMS (p-value = 0.09). CONCLUSION: The average diameter of distal RCA was smaller when compared to mid-RCA and proximal RCA. The average size of proximal LAD and proximal LCx was comparatively larger than mid- and distal LAD and LCx. The findings of current research will be beneficial for the diagnosis and management of coronary artery disease patients.

RESUMO

Ultrasound technique is one of the green technologies that is being utilized widely for varying food processes. Our aim in this study was to carry out ultrasonication, pasteurization and chemical preservation (Potassium metabisulfite) techniques on a carrot-orange juice blend. Additionally, the effect of these treatments on the storage period of about 21 days was also determined. The study displayed an array of results under the effect of different treatments. Throughout the storage period of 21 days' significant results were presented by the carrot juice blend subjected to the ultrasound technique (25 min) giving the highest values for total phenolic content (25.56 ± 1.29 mg GAE/100 mL), total antioxidant activity (573.48 ± 2.29 mg Trolox /100 mL), DPPH (32.32 ± 1.83 %) and reducing power (45.45 ± 1.92 mg AAE/100 mL) with least deterioration, followed by the blends treated with potassium metabisulfite (KMS) and pasteurization. The physicochemical analysis showed a non-significant effect of treatments on pH and total soluble solids (oBrix) of carrot-orange juice blends whereas, the changes in color parameters L*, a* and b* were noted to show changes in treated blends. Similarly, the results for the GC-MS quantification of volatile compounds displayed the highest concentrations in the ultrasonicated blends as compared to other techniques. The peak quantity was obtained for the hexanal (9903.43 ± 7.61 µg.kg-1) followed by 3-Methylbutanal (2638.7 ± 5.44 µg.kg-1), terpinolene (2337.16 ± 5.28 µg.kg-1), elemicin (2198.28 ± 5.28 µg.kg-1), myristicin (1936.62 ± 6.72 µg.kg-1). The use of sonication can effectively enhance the nutritional qualities of juice, as perceived by consumers.

RESUMO

Oral cancer patients suffer pain at the site of the cancer. Calcitonin gene related polypeptide (CGRP), a neuropeptide expressed by a subset of primary afferent neurons, promotes oral cancer growth. CGRP also mediates trigeminal pain (migraine) and neurogenic inflammation. The contribution of CGRP to oral cancer pain is investigated in the present study. The findings demonstrate that CGRP-immunoreactive (-ir) neurons and neurites innervate orthotopic oral cancer xenograft tumors in mice. Cancer increases anterograde transport of CGRP in axons innervating the tumor, supporting neurogenic secretion as the source of CGRP in the oral cancer microenvironment. CGRP antagonism reverses oral cancer nociception in preclinical oral cancer pain models. Single-cell RNA-sequencing is used to identify cell types in the cancer microenvironment expressing the CGRP receptor components, receptor activity modifying protein 1 Ramp1 and calcitonin receptor like receptor (CLR, encoded by Calcrl). Ramp1 and Calcrl transcripts are detected in cells expressing marker genes for Schwann cells, endothelial cells, fibroblasts and immune cells. Ramp1 and Calcrl transcripts are more frequently detected in cells expressing fibroblast and immune cell markers. This work identifies CGRP as mediator of oral cancer pain and suggests the antagonism of CGRP to alleviate oral cancer pain.

RESUMO

Post-Polio Syndrome (PPS) is a sequela of poliovirus infection that causes weakness in previously infected polio patients years after the initial infection. The diagnosis is one of exclusion and entails the following: 1) a prior episode of poliomyelitis with residual motor neuron function loss, 2) a period of at least 15 years or more after the acute onset of polio with neurologic and functional stability, and 3) a gradual onset of new weakness and abnormal muscle fatigability that has persisted for at least one year. While the exact etiology is unknown, the prevalence of PPS has increased as patients who have previously survived polio are getting older. In this report, we discuss a patient presenting to his primary care provider for evaluation of worsening lower extremity weakness over the course of the past three years. In addition to general characteristics of PPS, we will review the use of electromyography (EMG)/nerve conduction studies and imaging for evaluation. This report will also review prevention methods with vaccinations and identify potential treatment regimens including aerobic exercise and medications ranging from tricyclic antidepressants (TCAs) to dopamine agonists. The goal of this paper is to not only shine a light on PPS in general, but to show how social determinants i.e., economic stability, healthcare access and quality of health may affect the diagnosis of uncommon conditions.

RESUMO

OBJECTIVE: To investigate the quality of information related to glaucoma procedures found online using 2 different assessment tools. DESIGN: Cross-sectional survey of 100 web sites found via Google search engine. METHODS: The terms "peripheral iridotomy" and "trabeculectomy" along with synonymous keywords were inputted into Google's search engine. The first 50 functional websites for each term were assessed by 2 independent raters using the DISCERN instrument as well as a quality assessment tool by the Journal of the American Medical Association (JAMA). Statistical analysis included an evaluation of intra-rater reproducibility and interclass correlation between the 2 scales. MAIN OUTCOME MEASURES: (i) Quality of web site content based on DISCERN and JAMA scores, (ii) quality of web site based on categorization of web site (iii), intra-rater reproducibility of each scale, and (iv) interclass correlation between the 2 rating scales. RESULTS: Only 22% of the web sites for peripheral iridotomy and 34% of the web sites for trabeculectomy met all the criteria for JAMA's quality assessment. The mean DISCERN scores for peripheral iridotomy and trabeculectomy were 44 and 43.7, respectively, indicating poor quality. For the DISCERN scale, level of agreement between raters for each question ranged from κ = 0.550 (95% confidence interval [CI] 0.700-1.026) to κ = 0.884 (95% CI 0.751-1.017). For the JAMA 4 scale, level of agreement for each question ranged from κ = 0.874 (95% CI 0.734-1.01) to κ = 1.00. CONCLUSION: Our study indicates that information found online for two common ophthalmic procedures is of variable and poor quality. Thus, patients may be receiving misinformation online and better measures need to be implemented to avoid the dissemination of low-quality health information.

RESUMO

INTRODUCTION: Dyslipidemia refers to the presence of abnormalities in lipid parameters. It has become a global issue with a high risk of cardiovascular diseases (CVDs). The aim of the investigation was to find out the pattern and prevalence of dyslipidemia among patients with the acute coronary syndrome (ACS). METHODOLOGY: A cross-sectional study design was used. Data were collected using convenient sampling from 101 patients presenting with ACS, admitted at the critical care unit (CCU) / Rasheeda Begum Cardiac Centre (RBCC) of Shalamar Hospital, during a 12-month period from January 2020 to December 2021. Dyslipidemia is diagnosed by testing the lipid profile when there are one or more abnormal readings of the lipid profile. RESULTS: Nearly 43 (42.6%) had ST-segment elevation myocardial infarction (STEMI), 27 (26.7%) had non-ST segment elevation myocardial infarction (NSTEMI), and 31 (30.7%) were categorized as unstable angina (USA). Overall dyslipidemia was present in 84 (83.2%) patients. The prevalence of dyslipidemia was 55 (65%) in male patients and 29 (34.5%) in female patients. Dyslipidemia was present in 39 (90.7%) patients with STEMI, 25 (80.6%) in the USA, and 20 (74.1%) with NSTEMI. CONCLUSION: The prevalence of dyslipidemia was quite high among ACS patients. The proportion of obese patients was also high in our study. However, dyslipidemia was more frequent in overweight patients.
