Abstract
BACKGROUND Lean metabolic dysfunction-associated steatotic liver disease (MASLD), characterized by a BMI < 25 kg/m² (or < 23 kg/m² in Asians), presents a challenging prognosis compared to non-lean MASLD. This study examines cardiovascular outcomes in both lean and non-lean MASLD cohorts. METHODS In this meta-analysis, pooled odds ratios (ORs) within 95 % confidence intervals (CIs) were calculated for primary outcomes (cardiovascular mortality and major adverse cardiovascular events [MACE]) and secondary outcomes (cardiovascular disease [CVD], all-cause mortality, hypertension, and dyslipidemia). Studies comparing lean and non-lean MASLD within the same cohorts were analyzed, prioritizing those with larger sample sizes or recent publication dates. RESULTS Twenty-one studies were identified, encompassing lean MASLD patients (n = 7153; mean age 52.9 ± 7.4; 56 % male) and non-lean MASLD patients (n = 23,514; mean age 53.2 ± 6.8; 63 % male). Lean MASLD exhibited a 50 % increase in cardiovascular mortality odds compared to non-lean MASLD (OR: 1.5, 95 % CI 1.2-1.8; p < 0.0001). MACE odds were 10 % lower in lean MASLD (OR: 0.9, 95 % CI 0.7-1.2; p = 0.7), while CVD odds were 40 % lower (p = 0.01). All-cause mortality showed a 40 % higher odds in lean MASLD versus non-lean MASLD (p = 0.06). Lean MASLD had 30 % lower odds for both hypertension (p = 0.01) and dyslipidemia (p = 0.02) compared to non-lean MASLD. CONCLUSION Despite a favorable cardiometabolic profile and comparable MACE rates, lean individuals with MASLD face elevated cardiovascular mortality risk.

Abstract
Objectives To investigate extracts of the stem bark of Ziziphus jujuba (L.) Gaertn. var. hysudrica Edgew. (Rhamnaceae) for anti-inflammatory activity and isolate the active principle(s). Methods The dry powder was macerated separately in three types of solvents to prepare methanol extract (ME), ethyl acetate extract (EE), and chloroform extract (CE). Following in vitro anti-inflammatory screening, the most active extract was selected to isolate the active compound. Both, the active extract and isolated compound were further tested on rats using the carrageenan-induced inflammation model. The blood and paw tissue were subjected to qPCR, and histopathology, respectively. Key findings CE showed comparatively higher anti-inflammatory activity (85.0-95.0 %) in all in vitro assays, except the heat-induced membrane stabilization model (p < 0.05), and upon column chromatography, it yielded a pure crystalline compound. The compound was a pentacyclic triterpenoid (Lupane), named as hydroxymethyl (3β)-3-methyl-lup-20(29)-en-28-oate (Hussainate). CE (500 mg/kg) and Hussainate (1.0 mg/kg) reduced edema in 5 h after carrageenan administration. The activity of Hussainate was found to be comparable to that of dexamethasone (standard). The possible activity mechanism was the downregulation of tumor necrosis factor-alpha (TNF-α), cyclooxygenase-2 (COX-II), NF-κB, and IL-1β. Conclusions This study reveals that chloroform extract of the stem's bark of Z. jujuba may be used to prepare standardized anti-inflammatory herbal products using Hussainate as an active analytical marker. Hussainate may be used as a lead to develop anti-inflammatory drugs.

Abstract
BACKGROUND Limited data exists on the prognostic impact of valvular heart disease in cardiac amyloidosis (CA). We therefore sought to define the prevalence of valvular disease in patients with CA and assess the effects of significant valve disease on survival. METHODS This multi-center retrospective cohort study included consecutive patients with confirmed transthyretin (TTR) or light chain (AL) amyloidosis. Echocardiographic data closest to the date of amyloid diagnosis was reviewed, and severity was graded according to ASE guidelines. Kaplan-Meier survival analysis was performed to compare survival between patients with moderate or greater valve disease against those with mild or less disease. RESULTS We included 345 patients (median age 76 years; 73 % men; 110 AL, 235TTR). The median survival for the total patient cohort with cardiac amyloidosis was 2.92 years, with 30 % of patients surviving at five years after their diagnosis. Median survival comparing AL vs ATTR was 2.58 years vs 2.82 years (p = 0.67) The most common valvular abnormalities in the total cohort were mitral (62 %) and tricuspid (66 %).regurgitation There was a statistically significant difference in median survival between patients with no or mild MR compared to those with moderate or severe MR (2.92 years vs 3.35 years, p = 0.0047) (Fig. 5). There was a statistically significant difference in median survival in patients with no or mild TR compared to those with moderate or severe TR (3.35 years vs 2.3 years, p = 0.015). CONCLUSION Our study demonstrates a significant prevalence of mitral and tricuspid regurgitation in CA, with patients with moderate to severe MR and TR having a poorer prognosis.

Abstract
Data on utilization and safety of mitral Transcatheter Edge-to-Edge Repair (TEER) among hypertrophic cardiomyopathy (HCM) patients is limited. Our study aimed to assess the national utilization, safety, and clinical outcomes of TEER procedures among HCM patients using a nationwide real-world cohort. HCM patients undergoing TEER hospitalizations between 2015-2020 were identified using ICD-10 (International Classification of Diseases, (ICD-10-CM/PCS). HCM-TEER and HCM No-TEER formed the two comparison groups. Demographic characteristics, baseline comorbidities, procedural complications, inpatient mortality, length of stay (LOS), and cost of hospitalization were compared between the propensity-matched cohorts. Numeric values of 10 or less were not reported per NIS data use agreements. A total of 39,625 weighted cases of TEER were identified from 2015-2020. Of the included patients, 335 patients had the HCM diagnosis. The median age of the HCM-TEER group was 74 (70-79) vs. 79 (72-85) for the no-TEER cohort. The TEER procedure was more frequently performed among Caucasians (86.57%) and females (53.73%). The TEER procedure among HCM patients had similar in-hospital mortality (Adjusted odds ratio: aOR 1.50, 95% CI [0.68-3.29]; p = 0.30) and net adverse cardiac events (NACE) (aOR 1.16, 95% CI [0.73-1.85]; p = 0.51). TEER among HCM was associated with higher odds of gastrointestinal/hematological (aOR 2.33, 95% CI [1.29-4.19]; p = 0.003) complications. However, the odds of cardiac complications (aOR 0.57, 95% CI [0.33-0.96]; p = 0.03) were not higher. The median length of stay was similar in both the groups (median: 2 vs. 2, p = 0.74), although TEER among HCM was associated with higher costs of hospitalization ($44729.36 vs. $40513.82, p < 0.01). TEER is a minimally invasive procedure and could be a safe option for symptomatic HCM patients with significant MR who are poor surgical candidates. Mitral TEER among HCM has been increasingly utilized in recent years in the United States more commonly in obstructive HCM and is associated with no difference in mortality and net adverse cardiac events but higher odds for gastrointestinal/hematological complications than non-HCM patients.

Abstract
Despite advances in noninvasive imaging modalities to identify atrial fibrillation (AF) risk in Hypertrophic Cardiomyopathy (HCM), there is a paucity of evidence concerning the impact of low Left Atrial strain (LAS) on AF and major adverse cardiac events (MACE) incidence in these patients. This study investigated the diagnostic and prognostic significance of LAS in predicting AF and MACE in HCM. Findings revealed lower LA reservoir (MD: -11.79, 95% CI -14.83, -8.74; p<0.00001), booster (MD: -4.10, 95% CI -6.29, -1.91; p=0.0002), and conduit (MD: -7.52, 95% CI -9.39, -5.65; p<0.00001) strains in HCM patients versus healthy controls, and also indicated a significant association between low LA reservoir/conduit/booster strain and the development of new AF as well as MACE prevalence in HCM patients. The results from this study suggest the valuable role of LA strain in HCM and its utility in predicting the development of new AF and cardiac events in HCM patients.

Abstract
Background Previous studies have reported that tafamidis treatment was associated with better outcomes in patients with transthyretin amyloid cardiomyopathy (ATTR-CM) compared with those without tafamidis treatment. Therefore, we aimed to systematically assess the association of tafamidis treatment with outcomes in patients with ATTR-CM. Methods The protocol for this systematic review and meta-analysis was registered in the PROSPERO (CRD42022381985). Pubmed, Ovid Embase, Scopus, Cochrane Library, and Web of Science were interrogated to identify studies that evaluated the impact of tafamidis on prognosis in ATTR-CM, from January 1, 2000 to June 1, 2023. A random-effects model was used to determine the pooled risk ratio (RR) for the adverse endpoints. In addition, the main outcomes included all-cause death or heart transplantation, the composite endpoints included all-cause death, heart transplantation, cardiac-assist device implantation, heart failure exacerbations, and hospitalization. Findings Fifteen studies comprising 2765 patients (mean age 75.9 ± 9.3 years; 83.7% male) with a mean follow-up duration of 18.7 ± 17.1 months were included in the meta-analysis. There was a decrease in left ventricular ejection fraction (LVEF) (standard mean differences (SMD: -0.17; 95% confidence interval (CI), -0.31 to -0.03; P = 0.02) but were no significant differences in intraventricular septum (IVS) thickness or global longitudinal strain (GLS) after tafamidis treatment. However, subgroup analysis showed no significant deterioration in LVEF in the patients with wild-type ATTR after tafamidis treatment (SMD: -0.11; 95% CI, -0.34 to 0.12, P = 0.34). In addition, the group with tafamidis treatment had a decreased risk for all-cause death or heart transplantation compared to patients without treatment (the pooled RR, 0.44; 95% CI, 0.31-0.65; P < 0.01). Subgroup analysis showed that there was no significant difference of tafamidis on the outcomes in patients with wild-type or hereditary ATTR (RR, 0.44; 95% CI, 0.27-0.73 versus 0.21, 95% CI, 0.11-0.40, P = 0.08). Furthermore, tafamidis treatment was associated with a lower risk of the composite endpoint (RR, 0.57; 95% CI, 0.42-0.77; P < 0.01). Interpretation Our findings suggested that there was no significant deterioration in LVEF in the patients with wild-type ATTR after tafamidis treatment. In addition, tafamidis treatment was associated with a low risk of all-cause death and adverse cardiovascular events.

Abstract
BACKGROUND Tyrosine kinase inhibitors (TKIs) have been increasingly used as first-line therapy in hematologic and solid-organ malignancies. Multiple TKIs have been linked with the development of cardiovascular complications, especially atrial arrhythmias, but data on ventricular arrhythmias (VAs) is scarce. METHODS Herein we describe five detailed cases of VAs related to TKI use in patients with varied baseline cardiovascular risk factors between 2019 and 2022 at three centers. Individual chart review was conducted retrospectively. RESULTS Patient ages ranged from 43 to 83 years. Three patients were on Bruton's TKI (2 ibrutinib and 1 zanubrutinib) at the time of VAs; other TKIs involved were afatinib and dasatinib. Three patients had a high burden of non-sustained ventricular tachycardia (NSVT) requiring interventions, whereas two patients had sustained VAs. While all patients in our case series had significant improvement in VA burden after TKI cessation, two patients required new long-term antiarrhythmic drug therapy, and one had an implantable defibrillator cardioverter (ICD) placed due to persistent VAs after cessation of TKI therapy. One patient reinitiated TKI therapy after control of arrhythmia was achieved with antiarrhythmic drug therapy. CONCLUSIONS Given the expanding long-term use of TKIs among a growing population of cancer patients, it is critical to acknowledge the association of TKIs with cardiovascular complications such as VAs, to characterize those at risk, and deploy preventive and therapeutic measures to avoid such complications and interference with oncologic therapy. Further efforts are warranted to develop monitoring protocols and optimal treatment strategies for TKI-induced VAs.

Abstract
Introduction We sought to investigate the association between left-sided prosthetic valve dysfunction and gastrointestinal (GI) bleeding. Methods In a retrospective cohort of patients with left-sided prostheses, we identified those who experienced one or more GI bleeds. The latest or chronologically closest echocardiogram to the GI bleed was analyzed by a blinded investigator for prosthetic valve dysfunction. Results Among 334 unique patients, 166 had aortic prostheses, 127 had mitral prostheses, and 41 had both. A total of 58 (17.4%) subjects had GI bleeding events. Patients in the "GI Bleed" group had higher mean ejection fraction (56±14% vs. 49±15%; P = 0.003) and higher prevalence of hypertension, end-stage renal disease, and liver cirrhosis compared to the "No GI Bleed" group. There was a higher prevalence of moderate or severe prosthetic valve regurgitation in the GI Bleed vs. No GI Bleed group (8.6% vs. 2.2%; P = 0.027). Moderate or severe prosthetic valve regurgitation was independently associated with GI bleeding (odds ratio, 6.18; 95% confidence interval, 1.27-30.05; P = 0.024), after adjusting for ejection fraction, hypertension, end-stage renal disease and liver cirrhosis. Paravalvular regurgitation was associated with a higher incidence of GI bleeding compared to transvalvular regurgitation (35.7% vs. 11.9%; P = 0.044). The prevalence of prosthetic valve stenosis was similar between the GI Bleed and No GI Bleed groups (6.9% vs. 5.8%; P = 0.761). Conclusion In a cohort of patients with predominantly surgically placed prosthetic valves, moderate to severe left-sided prosthetic valve regurgitation was independently associated with GI bleeding.

Abstract
Type 2 Diabetes Mellitus (T2DM) and cardiac hypertrophy (CH) are among the top ten leading cause of deaths, worldwide. T2DM and cardiac hypertrophy are the chronic diseases, have close association and direct life-threatening complications like stroke, myocardial infarction, retinopathy, nephropathy, and limb amputation. In addition to other medical approaches, miRNAs-based strategy is considered most efficient for early detection of chronic diseases and also has potential for the treatment of T2DM and cardiac hypertrophy like it is being used for cancer in clinical trials. MicroRNAs (miRNAs) are single stranded (non-coding) of 20 to 22 nucleotides sequences which bind to their target mRNA upon the complimentary basis, to silence the protein expression at post transcriptional level. Bioinformatic databases are used like online mendelian inheritance in man (OMIM), gene testing registry (GTR), TargetScan and ShinyGO for validation of disease linked genes and sorting the common miRNAs in both diseases, such as miR-30-5p/101-3p.2/190-5p/506-3p/9-5p/128-3p/137/96-5p/7-5p/107/101-3p.1/98-5p/124-3p.2/124-3p.116-5p/15-5p/497-5p/ 424-5p/195-5p/1271-5p, let-7-5p. Aforementioned databases were also used for the miRNAs which have more than one disease linked genes target in each pathological condition. Such miRNAs for cardiac hypertrophy are: miR-19-3p/183-5p.2/153-3p/372-3p/302-3p/520-3p/373-3p/129-5p/144-3p/139-5p and for T2DM are: miR-27-3p/206/1-3p/181-5p. This finding would be helpful for the appropriate selection of miRNAs and to design applicable research project in future. It will require more validation by using the miRNAs expression analysis, mimic, and anti-miRNA approach to check their potential against cardiac hypertrophy and T2DM.

Abstract
Abstract
Issue/problem
The United Kingdom (UK) hosts c.136,000 refugees and last year received the most asylum applications in two decades. Despite this, expertise in migrant health is not widespread in general practice, with few comprehensive toolkits available to support crucial initial health assessments of new arrivals.
Description of the problem
A large influx of Afghan refugees entered the UK in autumn 2021. In London, primary care practitioners quickly identified a lack of readily accessible, comprehensive guidance to support them in conducting health assessments for arrivals with a complex range of needs. This was compounded by many in primary care having little or no experience of migrant health.
Results
To address this gap in advice on conducting initial health assessments, a bespoke toolkit was created. The toolkit consolidated advice from a range of partners and resources: the UK Afghan migrant health guide, clinicians with humanitarian experience, front-line practitioners, Doctors of the World, and those leading on the health and public health response. The toolkit ensured greater consistency in the nature and content of assessments, considered not only primary needs but also broader wellbeing, and was responsive to both anticipated and known health priorities.
Lessons
The initial health assessment toolkit for Afghan migrants was well received by frontline staff and has implications for international practice in other areas providing similar health support. The toolkit and associated supporting information has formed a template that can be rapidly adapted to suit emerging needs, as has been done for new arrivals from Ukraine. This work has fed into best practice by the UK National Asylum Steering Group and is to be a case study for a WHO project on country-specific health assessments.
Key messages
• The toolkit is a proof of concept for partnership working towards holistic initial health assessments of new migrants in primary care, bringing together best evidence and pragmatic practice.
• This work has implications for other countries experiencing similar trends in migration and providing health support to an increasing number of new refugees.

Abstract
Abstract
Background
Myocardial dysfunction is well established in systemic sclerosis (SSc). The utility of standard echocardiography is limited to detect the onset of myocardial dysfunction. Speckle tracking echocardiography (STE) and strain imaging has emerged as a useful technique to quantify left ventricle hemodynamics and myocardial function in early stages of myocardial dysfunction. We aimed to systematically analyze the existing literature on the application of STE and strain analysis in identifying SSc associated myocardial dysfunction
Methods
PubMed, Cochrane, and Google Scholar were queried for studies from the inception of the databases to 2022. Case control studies that used 2D STE for assessment of strain in SSc patients and controls, were included for the analysis. PRISMA guidelines were followed for selections of studies. Two independent reviewers extracted data. Analysis was done using Cochrane Review Manager 5.0.
Results
Total of 19 studies were included in the analysis that compared strain analysis in SSc patient's vs healthy controls. Of the 16 studies that reported left ventricular (LV) global longitudinal strain, we found significantly lower LV global longitudinal strain in SSc patients (mean difference 1.92; 95% CI 0.98–2.87). Six studies reported LV circumferential strain which was noted to be lower in SSc patients compared to healthy controls (mean difference 3.55; 95% CI 1.60–5.51). Five studies reported LV global radial strain with a similar decrease in radial strain among SSc patients compared to controls (mean difference 4.39; 95% CI −6.95 to −1.83). 10 studies reported right ventricular longitudinal strain with a decrease in longitudinal strain in SSc patient's vs controls (mean difference 2.57; 95% CI 2.03–3.12).
Conclusions
SSc patients have lower strain values compared to controls, which is suggestive of an impaired myocardial function in left and right ventricle. Strain analysis by STE could help with early detection of myocardial dysfunction.

Abstract
BACKGROUND Tafamidis is the only therapy shown to improve survival in transthyretin cardiac amyloidosis (ATTR) based on randomized controlled trial data. OBJECTIVES We sought to evaluate the impact of tafamidis on survival in a real-world community based cohort. METHODS This was a prospective observational cohort study that included consecutive patients with confirmed ATTR based on biopsy or TcPYP imaging. Baseline characteristics were compared between patients taking tafamidis versus not, and Kaplan-Meier survival analysis was performed to compare survival between these groups. We examined the reasons that ATTR patients were not on tafamidis. RESULTS Of 107 ATTR patients, median age was 83.9 years, 79% were men, and 63 (59%) of them were on tafamidis. Demographics and baseline cardiovascular risk factors did not differ significantly between those on versus off tafamidis, although there was a higher proportion of NYHA Class III or IV heart failure in those off tafamidis (76% vs 57%, p<.01). The most common reasons patients were not on tafamidis included delays in obtaining the drug or financial barriers (59%) and NYHA Class IV heart failure (19.5%). Patients taking tafamidis had a significantly higher median survival compared to those not on tafamidis (median survival 6.70 vs 1.43 years, p<.0001). CONCLUSIONS Our study demonstrates significantly improved survival in ATTR patients taking tafamidis. Barriers exist to tafamidis initiation including delayed access and affordability, and efforts should be made to improve patient access.

Abstract
BACKGROUND Data on the diagnostic and prognostic value of subtle abnormalities on myocardial perfusion imaging (MPI) are limited. METHODS AND RESULTS In a retrospective single-center cohort of patients who underwent regadenoson SPECT-MPI, near-normal MPI was defined as normal left ventricular ejection fraction (LVEF ≥ 50%) and a summed stress score (SSS) of 1-3 vs SSS = 0 in normal MPI. Borderline ischemia was defined as normal LVEF, SSS = 1-3, and a summed difference score (SDS) of 1 vs SDS = 0 in the absence of ischemia. Coronary angiography data within 6 months from MPI were tabulated. Patients were followed for cardiac death (CD), myocardial infarction (MI), coronary revascularization (CR), and Late CR (LCR) [> 90 days post MPI]. Among 6,802 patients (mean age, 62 ± 13 years; 42% men), followed for a mean of 2.5 ± 2.1 years, 4,398 had normal MPI, 2,404 had near-normal MPI, and 972 had borderline ischemia. Among patients who underwent angiography within 6 months, obstructive (≥ 70% or left main ≥ 50%) CAD was observed at higher rates among subjects with near-normal MPI (33.5% vs 25.5%; P = .049) and those with borderline ischemia (40.5% vs 25.8%; P = .004). During follow-up, 158 (2.3%) CD/MI, 246 (3.6%) CR, and 150 (2.2%) LCR were observed. Near-normal MPI (SSS = 1-3), compared to normal MPI (SSS = 0), was not associated with a significant difference in the risk of the composite endpoint of CD/MI (Hazard ratio [HR], 1.21; 95% confidence interval [CI], .88-1.66; P = .243) or LCR (HR 1.28; CI .93-1.78; P = .130), but was associated with a significant increase in the risk of CR (HR 1.91; CI 1.49-2.46; P < .001). Borderline ischemia (SDS = 1), compared to no ischemia (SDS = 0), was not associated with a significant difference in the risk of CD/MI [HR 1.09; CI .70-1.69; P = .693], but was associated with a significant increase in the risk of CR (HR 5.62; CI 3.08-10.25; P < .001) and LCR (HR 2.98; CI 1.36-6.53; P = .006). CONCLUSION Near-normal MPI and borderline ischemia on SPECT-MPI provide no significant prognostic information in predicting hard cardiac events but are associated with higher rates of obstructive angiographic CAD and coronary revascularizations.

Abstract
Abstract
Aim
There is a well-documented increase in incidence of thyroid cancer in individuals living within the blast radius at the time of the Chernobyl nuclear disaster. Following a case encountered in our clinical practice of a patient born within the blast radius but after the blast itself, we aimed to evaluate the evidence of increased thyroid cancer within such a cohort.
Method
We reviewed the existing literature for evidence for or against an increase in thyroid cancer in this population group. Identified articles were reviewed and appraised, evaluating the evidence for any possible increase in incidence.
Results
Very few papers looked at risk in such a population, but those identified suggested no increase in risk of thyroid cancer in individuals born within the radius, after the blast.
Conclusions
We conclude there is little evidence supporting routine monitoring for individuals born within the blast radius after the blast, and as such this should be included in the British Thyroid Association guidelines.

Abstract
BACKGROUND Valvular heart disease (VHD) is a known cardiac manifestation of systematic lupus erythematosus (SLE). This systematic review aims to pool data from studies to estimate the frequency of valvular lesions in SLE patients. It also aims to demonstrate the association between VHD in SLE and antiphospholipid antibodies positivity. METHODS We included 27 studies after identifying relevant abstracts from PubMed, Scopus, and Google Scholar from the time of inception of database to 2019. Inclusion criteria consisted of English-language case-control and cohort studies. Three reviewers independently performed study selection, data extraction, and quality assessment using the Newcastle-Ottawa Scale for assessing risk for bias. RESULTS For VHD in SLE patients, the most commonly involved valve was the mitral valve, with 19.7% lesions being mitral regurgitation. In terms of morphological lesions, valve thickening (11.06%) and vegetations (11.76%) were among the most prevalent. Other commonly encountered lesions were mitral valve prolapse and tricuspid regurgitation in 9.25% and 10.86% of patients, respectively. A meta-analysis of 21 studies with 2163 SLE patients, of which 23.3% had valvular lesions, showed a significant association of anticardiolipin antibodies positivity with VHD (relative risk, 1.55; confidence interval, 1.10-2.18). CONCLUSIONS Systemic lupus erythematosus is associated with VHD, and it should be considered a clinical manifestation of SLE in the absence of other valvular pathologies. There is a clear association between VHD in SLE and immunoglobulin G anticardiolipin antibodies positivity. This association suggests that this subgroup of SLE patients might benefit from a screening echocardiogram.

Abstract
Thalidomide is a medication that has been in existence for over half a century, and has proven to be useful and effective in severe dermatological conditions. For dermatologists, the ability of thalidomide to reduce the levels of the cytokine tumour necrosis factor-α, along with its immunomodulatory and anti-angiogenic properties, is of great significance, with the added advantage of being an oral medication. Its use is of course strictly monitored, owing to its potential adverse effects (AEs), particularly teratogenicity, with precautions taken to ensure its safe and correct use by both prescriber and patient. In this review, we look at the background and mechanism of action of thalidomide, provide an overview of conditions it can be used for with case examples, explain the potential AEs and monitoring requirements, and discuss future developments.

Abstract
Abstract
Introduction
Gorlin Goltz syndrome (GGS) is a rare, hereditary, AD condition with multiple BCCs, odontogenic keratocysts (Jaw cysts), calcification of falx cerebri, skeletal anomalies & a predisposition to neoplasms like medulloblastomas, fibromas and rhabdomyosarcomas.
Aim
We present a rare case of a Squamous cell carcinoma (SCC) developing in a Maxillary odontogenic keratocyst in a 32-year male with GGS.
Discussion
This patient was referred to the OMFS unit with a non-healing UL3 extraction socket and exophytic growth. Initial biopsies suggested an atypical squamo-proliferative lesion, however a repeat biopsy demonstrated an invasive SCC arising from a background odontogenic keratocyst of the maxilla. He was initially reluctant to undergo a staging CT scan to avoid risks of developing further BCCs due to IR exposure. This was eventually performed as per H&N MDT recommendation & showed a T4aN0M0 SCC of the left maxilla and bilateral multiple mandibular odontogenic keratocysts. He underwent a left maxillectomy, left neck dissection & reconstruction with a DCIA free flap, but did not want his mandibular keratocysts treated at the same time. Complete tumour clearance was achieved with no involved neck nodes & he remains disease-free at 4 months postoperatively. Although for a T4 tumour he would have needed postoperative radiotherapy, in view of the GGS, no adjuvant treatment was indicated.
Conclusions
SCC developing in a maxillary OKC is exceedingly rare with only two previous cases reported in GG syndrome. This is the first reported case of a GGS patient with oral SCC undergoing a complex free flap reconstruction.

Abstract
This study was conducted to appraise the effects on egg quality and production performance of laying hens when drinking water was supplemented with calcium (Ca) and magnesium (Mg). A total of 384 (64-week-old) Hy-line Brown laying hens were assigned at random to four treatments, which consisted of CON: unsupplemented drinking water; T1: drinking water + 2 mg/L Ca + 250 mg/L Mg; T2: drinking water + 4 mg/L Ca + 510 mg/L Mg /10 L; and T3: drinking water + 5 mg/L Ca and 760 mg/L Mg. The experiment lasted six weeks. Water intake increased linearly in week 1 with the rising levels of Ca and Mg in the drinking water. Increasing the Ca and Mg levels improved eggshell strength (week 2 (P =0.01), week 5 (P =0.01), and week 6 (P = 0.03), and eggshell thickness (week 6) (P =0.02) and reduced the rate at which eggs were broken (week 4) (P =0.01). The supplemental Ca and Mg did not affect egg production, egg weight, Haugh unit, albumen height, eggshell colour, and yolk colour compared with CON. Nor did they influence the Haugh unit and albumen height after storing for 1, 5, 10 and 15 days. In conclusion, adding Ca and Mg to the drinking water increased the thickness and strength of the eggshells.

Abstract
Merkel cell carcinoma (MCC) of the skin is a rare, aggressive form of skin cancer that metastasizes to other parts of the body. This cutaneous neuroendocrine tumour mainly affects older people, with most cases generally occurring over the age of 50 years. Merkel cell polyomavirus has been shown to induce gene mutations resulting in this skin cancer, with immunosuppression and ultraviolet radiation being other key risk factors in its pathogenesis. MCC is clinically seen as a rapidly enlarging, isolated, irregular erythematous nodule typically found on sun-exposed sites. Diagnosis is through clinical examination followed by tissue biopsy, which demonstrates characteristic histopathological neuroendocrine features. Immunohistochemistry plays a crucial role in diagnosis with the characteristic perinuclear staining with cytokeratin-20 helping to differentiate it from other morphologically similar tumours. Sentinel lymph node biopsy and imaging is essential for staging and determining prognosis. Surgical excision is the mainstay of treatment for localized disease although adjuvant radiotherapy is often required. Metastatic disease involves a very poor prognosis, and immune checkpoint inhibitors have recently shown promise in the treatment of metastatic disease. Avelumab, a monoclonal antibody that binds to the programmed death-1 receptor, has been approved by the National Institute for Health and Care Excellence and shown encouraging survival outcomes. It provides an option for treating metastatic carcinoma in adults after they have failed ≥ 1 line of chemotherapy for metastatic disease.

Abstract
Acute rheumatic fever (ARF) describes the non-suppurative and autoimmune inflammation of joint, muscle, and fibrous tissue that occurs after group A streptococcal (GAS) pharyngitis. This report describes a rare case of a 39-year-old male with migratory arthralgias as a presenting sign of ARF. Through this case, we review the current literature on ARF and highlight clinical and objective findings that differentiate ARF from similar presenting arthralgias, specifically post-streptococcal reactive arthritis (PSRA). With this report, we hope to increase clinical suspicion for ARF in patients with acute joint pain, as differentiating ARF from other arthritides, PSRA specifically, determines management strategy and need for secondary prophylaxis against rheumatic heart disease.

Abstract
Cardiac papillary fibroelastoma is a benign neoplasm that arises in the endocardium. It commonly presents as an incidental finding on transthoracic echocardiography or as emboli to the coronary, cerebral or pulmonary vasculature. Clinical manifestations described in the literature have generally been related to a sequelae of the associated embolic phenomenon of these lesions. Valve regurgitation is less common with papillary fibroelastoma and when found, it is not known to cause severe regurgitation requiring valve replacement. We report a case of papillary fibroelastoma in a patient with severe mitral and aortic valve regurgitation in association with mobile masses requiring double valve replacement. This patient managed initially as infective endocarditis with severe double valve regurgitation, was found to have valvular masses concernng for papillary fibroelastoma and subsequently confirmed on pathology.

Abstract
Clostridium perfringens (C. perfringens) is a normal inhabitant in the gut of animals. It may proliferate rapidly in favorable conditions and produces lethal toxins. These toxins may cause lethal effects in the intestines and systemically it may cause enterotoxaemia. In disease conditions, the presence of C. perfringens CFU/g in fecal sample can be of diagnostic value. This study aims to determine the bacterial counts and predisposing factors of C. perfringens (targeting CPA gene) infection in addition to an in-vitro antimicrobial trial in entero-toxemic sheep in Pakistan. A total of 192 diarrheic sheep irrespective of age, gender and breed were selected and the CFU/g was determined from the fecal samples. The study showed that 34.9% of the samples had elevated level of bacterial count compared to the normal (104-107 CFU/g). Out of the total, 7.8% of the samples had subnormal bacterial count (CFU/g), while, 57.3% of the samples showed bacterial counts in the normal ranges. The confirmation of selectively isolated C. perfringens was done by amplification of 324bp CPA gene fragment using polymerase chain reaction (PCR). The in-vitro antimicrobial sensitivity trials showed that penicillin, ciprofloxacin and ceftriaxone are 100% efficacious against C. perfringens, while, bacitracin, ampicillin and amoxicillin were found to be least effective. The key determinants in this study which support the in-vivo growths of C. perfringens were; carbohydrate rich diet and overcrowding with the odds ratios (OR) of 5.44 and 2.26, respectively. This study concludes that C. perfringens is highly prevalent in sheep population of Pakistan. The incidence of enterotoxaemia can be minimized by controlling the factors which enhance its in-vivo growth. The diseased animal associated with elevated C. perfringens levels can be effectively cured using any one of the penicillin, ciprofloxacin and ceftriaxone.

Abstract
The main biochemical hallmark of the rare and lethal condition of Donohue syndrome (DS) is hyperinsulinemia. The roles of the gut and other pancreatic hormones involved in glucose metabolism, satiety and energy expenditure have not been previously reported in DS. Two siblings with genetically confirmed DS and extremely low weight underwent a mixed meal (MM) test where pancreatic hormones insulin, C-peptide, glucagon, active amylin, pancreatic polypeptide (PP) as well as gut hormones active glucagon-like peptide 1 (GLP-1), glucose-dependent insulinotropic peptide (GIP), ghrelin, peptide YY (PYY) and leptin were analyzed using a Multiplex assay. Results were compared to those of 2 pediatric controls. As expected, concentrations of insulin, C-peptide and amylin were very high in DS cases. The serum glucagon concentration was undetectable at the time of hypoglycemia. GIPs concentrations were lower in the DS, however, this was not mimicked by the other incretin, GLP-1. Ghrelin concentrations were mainly undetectable (<13.7 pg/mL) in all participants. DS cases had higher PYY and dampened PP concentrations. Leptin levels remained completely undetectable (<137.0 pg/mL). Patients with DS have extremely high amylin levels, completely undetectable serum glucagon and leptin levels with abnormal satiety regulating hormone PP with a relatively normal ghrelin response during a MM test. The low serum GIP might be acting as physiological brake on insulin secretion. The undetectable serum leptin levels suggest the potential of using leptin analogues as therapy for DS patients.

Abstract
BACKGROUND In addition to inhibiting epidermal growth factor receptor (EGFR) signaling, anti-EGFR antibodies of the IgG1 'subtype' can induce a complementary therapeutic effect through the induction of antibody-dependent cell-mediated cytotoxicity (ADCC). Glycoengineering of therapeutic antibodies increases the affinity for the Fc-gamma receptor, thereby enhancing ADCC. PATIENTS AND METHODS We investigated the changes in immune effector cells and EGFR pathway biomarkers in 44 patients with operable, advanced stage head and neck squamous cell carcinoma treated with two preoperative doses of either glycoengineered imgatuzumab (GA201; 700 or 1400 mg) or cetuximab (standard dosing) in a neoadjuvant setting with paired pre- and post-treatment tumor biopsies. RESULTS Significant antitumor activity was observed with both antibodies after just two infusions. Metabolic responses were seen in 23 (59.0%) patients overall. One imgatuzumab-treated patient (700 mg) achieved a 'pathological' complete response. An immediate and sustained decrease in peripheral natural killer cells was consistently observed with the first imgatuzumab infusion but not with cetuximab. The functionality of the remaining peripheral natural killer cells was maintained. Similarly, a pronounced increase in circulating cytokines was seen following the first infusion of imgatuzumab but not cetuximab. Overall, tumor-infiltrating CD3+ cell counts increased following treatment with both antibodies. A significant increase from baseline in CD3+/perforin+ cytotoxic T cells occurred only in the 700-mg imgatuzumab group (median 95% increase, P < 0.05). The most prominent decrease of EGFR-expressing cells was recorded after treatment with imgatuzumab (700 mg, -34.6%; 1400 mg, -41.8%). The post-treatment inflammatory tumor microenvironment was strongly related to baseline tumor-infiltrating immune cell density, and baseline levels of EGFR and pERK in tumor cells most strongly predicted therapeutic response. CONCLUSIONS These pharmacodynamic observations and relationship with efficacy are consistent with the proposed mode of action of imgatuzumab combining efficient EGFR pathway inhibition with ADCC-related immune antitumor effects. CLINICAL TRIAL REGISTRATION NUMBER NCT01046266 (ClinicalTrials.gov).

Abstract
Cotton dusky bug (Oxycarenus spp.) mostly attack on cash crops such as Gossypium, Cola and Hibiscus which affect the national economy therefore sustainable pest management is needed. Cytochrome c oxidase I (COI) gene is utilized as marker gene for DNA barcoding, genetic and ecological study of insects. In present study insect (cotton dusky bug) samples were collected from cotton fields in Faisalabad. COI gene was amplified from genomic DNA of bug and cloned into pTZ57R/T vector (Fermentas). The clone was sent to Macrogen (South Korea) for Sanger sequencing. The phylogenetic analysis and pairwise multiple sequence alignment showed that our cotton dusky bug grouped with two species of Oxycarenus genus and highest sequence identity was 91.1% with Oxycarenus hylinipennis. This is the first report of genetic barcode of Oxycarenus hylinipennis from cotton from Pakistan.

Abstract
Congenital hyperinsulinaemic hypoglycaemia (HH) can occur in isolation or it may present as part of a wider syndrome. For approximately 40%-50% of individuals with this condition, sequence analysis of the known HH genes identifies a causative mutation. Identifying the underlying genetic aetiology in the remaining cases is important as a genetic diagnosis will inform on recurrence risk, may guide medical management and will provide valuable insights into β-cell physiology. We sequenced the exome of a child with persistent diazoxide-responsive HH, mild aortic insufficiency, severe hypotonia, and developmental delay as well as the unaffected parents. This analysis identified a de novo mutation, p.G403D, in the proband's CACNA1D gene. CACNA1D encodes the main L-type voltage-gated calcium channel in the pancreatic β-cell, a key component of the insulin secretion pathway. The p.G403D mutation had been reported previously as an activating mutation in an individual with primary hyper-aldosteronism, neuromuscular abnormalities, and transient hypoglycaemia. Sequence analysis of the CACNA1D gene in 60 further cases with HH did not identify a pathogenic mutation. Identification of an activating CACNA1D mutation in a second patient with congenital HH confirms the aetiological role of CACNA1D mutations in this disorder. A genetic diagnosis is important as treatment with a calcium channel blocker may be an option for the medical management of this patient.

Abstract
A new UV-Visible spectroscopic method assisted with microwave for the determination of glucose in pharmaceutical formulations was developed. In this study glucose solutions were oxidized by ammonium molybdate in the presence of microwave energy and reacted with aniline to produce a colored solution. Optimum conditions of the reaction including wavelength, temperature, and pH of the medium and relative concentration ratio of the reactants were investigated. It was found that the optimal wavelength for the reaction is 610 nm, the optimal reaction time is 80s, the optimal reaction temperature is 160°C, the optimal reaction pH is 4, and the optimal concentration ratio aniline/ammonium molybdate solution was found to be 1:1. The limits of detection and quantification of the method are 0.82 and 2.75 ppm for glucose solution, respectively. The use of microwaves improved the speed of the method while the use of aniline improved the sensitivity of the method by shifting the wavelength.
