Abstract
Extracellular matrix-based bio-scaffolds are useful for tissue engineering as they retain the unique structural, mechanical, and physiological microenvironment of the tissue thus facilitating cellular attachment and matrix activities. However, considering its potential, a comprehensive understanding of the protein profile remains elusive. Herein, we evaluate the impact of decellularization on the human amniotic membrane (hAM) based on its proteome profile, physicochemical features, as well as the attachment, viability, and proliferation of umbilical cord-derived mesenchymal stem cells (hUC-MSC). Proteome profiles of decellularized hAM (D-hAM) were compared with hAM, and gene ontology (GO) enrichment analysis was performed. Proteomic data revealed that D-hAM retained a total of 249 proteins, predominantly comprised of extracellular matrix proteins including collagens (collagen I, collagen IV, collagen VI, collagen VII, and collagen XII), proteoglycans (biglycan, decorin, lumican, mimecan, and versican), glycoproteins (dermatopontin, fibrinogen, fibrillin, laminin, and vitronectin), and growth factors including transforming growth factor beta (TGF-β) and fibroblast growth factor (FGF) while eliminated most of the intracellular proteins. Scanning electron microscopy was used to analyze the epithelial and basal surfaces of D-hAM. The D-hAM displayed variability in fibril morphology and porosity as compared with hAM, showing loosely packed collagen fibers and prominent large pore areas on the basal side of D-hAM. Both sides of D-hAM supported the growth and proliferation of hUC-MSC. Comparative investigations, however, demonstrated that the basal side of D-hAM displayed higher hUC-MSC proliferation than the epithelial side. These findings highlight the importance of understanding the micro-environmental differences between the two sides of D-hAM while optimizing cell-based therapeutic applications.

Abstract
Intellectual disability is a heterogeneous disorder, diagnosed using intelligence quotient (IQ) score criteria. Currently, no specific clinical test is available to diagnose the disease and its subgroups due to inadequate understanding of the pathophysiology. Therefore, current study was designed to explore the molecular mechanisms involved in disease perturbation, and to identify potential biomarkers for disease diagnosis and prognosis. A total of 250 participants were enrolled in this study, including 200 intellectually disabled (ID) subjects from the subgroups (mild, moderate, and severe) with age and gender matched healthy controls (n = 50). Initially, IQ testing score and biochemical profile of each subject was generated, followed by label-free quantitative proteomics of subgroups of IQ and healthy control group through nano-LC/MS- mass spectrometry. A total of 310 proteins were identified, among them198 proteins were common among all groups. Statistical analysis (ANOVA) of the subgroups of ID showed 142 differentially expressed proteins, in comparison to healthy control group. From these, 120 proteins were found to be common among all subgroups. The remaining 22 proteins were categorized as exclusive proteins found only in disease subgroups. Furthermore, the hierarchical cluster analysis (HCL) of common significant proteins was also performed, followed by PANTHER protein classification and GO functional enrichment analysis. Results provides that the datasets of differentially expressed proteins, belong to the categories of immune / defense proteins, transfer carrier proteins, apolipoproteins, complement proteins, protease inhibitors, hemoglobin proteins etc., they are known to involvein immune system, and complement and coagulation pathway cascade and cholesterol metabolism pathway. Exclusively expressed 22 proteins were found to be disease stage specific and strong PPI network specifically those that have significant role in platelets activation and degranulation, such as Filamin A (FLNA). Furthermore, to validate the mass spectrometric findings, four highly significant proteins (APOA4, SAP, FLNA, and SERPING) were quantified by ELISA in all the study subjects. AUROC analysis showed a significant association of APOA4 (0.830), FLNA (0.958), SAP (0.754) and SERPING (0.600) with the disease. Apolipoprotein A4 (APOA4) has a significant role in cholesterol transport, and in modulation of glucose and lipid metabolism in the CNS. Similarly, FLNA has a crucial role in the nervous system, especially in the functioning of synaptic network. Therefore, both APOA4, and FLNA proteins represent good potential for candidate biomarkers for the diagnosis and prognosis of the intellectual disability. Overall, serum proteome of ID patients provides valuable information of proteins/pathways that are altered during ID progression.

Abstract
BACKGROUND Immunotherapy has transformed the endometrial cancer treatment landscape, particularly for those exhibiting mismatch repair deficiency [MMRd/microsatellite instability-hypermutated (MSI-H)]. A growing body of evidence supports the integration of immunotherapy with chemotherapy as a first-line treatment strategy. Recently, findings from ongoing trials such as RUBY (NCT03981796), NRG-GY018 (NCT03914612), AtTEnd (NCT03603184), and DUO-E (NCT04269200) have been disclosed. MATERIALS AND METHODS This paper constitutes a review and meta-analysis of phase III trials investigating the role of immunotherapy in the first-line setting for advanced or recurrent endometrial cancer. RESULTS The pooled data from 2320 patients across these trials substantiate the adoption of chemotherapy alongside immunotherapy, revealing a significant improvement in progression-free survival compared to chemotherapy alone [hazard ratio (HR) 0.70, 95% confidence interval (CI) 0.62-0.79] across all patient groups. Progression-free survival benefits are more pronounced in MMRd/MSI-H tumors (n = 563; HR 0.33, 95% CI 0.23-0.43). This benefit, albeit less robust, persists in the MMR-proficient/microsatellite stable group (n = 1757; HR 0.74, 95% CI 0.60-0.91). Pooled data further indicate that chemotherapy plus immunotherapy enhances overall survival compared to chemotherapy alone in all patients (HR 0.75, 95% CI 0.63-0.89). However, overall survival data maturity remains low. CONCLUSIONS The incorporation of immunotherapy into the initial treatment for advanced and metastatic endometrial cancer brings about a substantial improvement in oncologic outcomes, especially within the MMRd/MSI-H subset. This specific subgroup is currently a focal point of investigation for evaluating the potential of chemotherapy-free regimens. Ongoing exploratory analyses aim to identify non-responding patients eligible for inclusion in clinical trials.

Abstract
Scorpion venoms are known to contain over 100,000 biologically active constituents. However, only a few of them have been studied. The major constituents of venom are proteins and peptides, which exhibit various biological and pharmacological properties, including anticancer activities. In the current study, the venom of yellow scorpions (Buthus sindicus) found in Sindh, Pakistan, was extracted and evaluated for its anti-cancer and anti-inflammatory activities. The crude venom showed a dose dependent inhibition of phagocyte oxidative burst from human whole blood cells (28.3% inhibition at highest tested concentration of 300 μg/mL). In-vitro cytotoxicity of crude venom was evaluated against human prostrate (PC3), cervical (HeLa) and neuroblastoma (U87-MG) cell lines, along with cytotoxicity against normal human fibroblast (BJ) cells. Crude venom was cytotoxic to all cell lines, with prominent inhibitory effect on PC3 cells. Crude venom was fractionated through RP-UPLC, resulted in fifteen fractions, followed by evaluation of their anticancer potential. Among all, the fraction I significantly (P < 0.001) reduced the cell viability of all three cancer cell lines, and exhibited insignificant cytotoxicity against normal cell line. Furthermore, the apoptotic cell death pathway was evaluated for crude venom, and fraction I, in most sensitive cell line PC3, by using flow-cytometry analysis. Both crude venom and its fraction I caused a mitochondrial-mediated apoptosis in prostate cancer cells (PC3). To the best of our knowledge, this is the first report of the anticancer and anti-inflammatory activity of venom of Pakistani yellow scorpions. Results indicate their therapeutic potential, and a case for further purification and validation studies.

Abstract
The most prevalent solar ultraviolet radiation is ultraviolet-A (UVA) radiation. It is the inducer of reactive oxygen species (ROS), a potent mediator of inflammation and photocarcinogenesis. Regular application of sunscreens containing UVA filters is an effective preventive measure in mitigating the risk associated with the formation of dermal carcinoma. Therefore, the development of new photoprotective agents is of great need. The current work examined the in vitro photoprotection of the aryl-linked (thio)semicarbazone derivatives against UVA-mediated DNA damage, inflammation, reactive nitrogen species (RNS), and ROS. Except for the inflammatory cytokine assay, which was carried out on the human monocytic leukemia (THP-1) cell line, all tests were conducted on the human dermal fibroblast (BJ) cell line. In comparison to benzophenone (reference compound), the compound (2Z, 2'Z)-2,2'-(1,3-Phenylenebis (methanylylidene)) bis (hydrazine-1-carbothioamide) (DD-21) demonstrated considerable protection against UVA-induced damage. Compared to the UVA-irradiated control, DD-21 significantly decreased the levels of nitric oxide (NO) and ROS (p < 0.001). In the presence of DD-21, the release of UVA-induced pro-inflammatory cytokines, tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β), was also significantly reduced (p < 0.05). Moreover, it was observed that DD-21 protected the cells from UVA-mediated DNA strand breaks and also inhibited the formation of cyclobutane pyrimidine dimers (CPDs) upon comparison to the UVA-exposed control cells (p < 0.001). In conclusion, the findings of this study revealed that DD-21 exhibits remarkable photoprotective properties, thus demonstrating its potential as a candidate UVA filter.

Abstract
IMPORTANCE Multi-drug resistance (MDR) by virtue of evolving resistance and virulence mechanisms among A. baumannii is a global concern which is responsible for lethal hospital-acquired infections. Therefore, it is crucial to develop new therapeutics against it. Metal complexes are compact structures with diverse mechanisms that the pathogens cannot evade easily which make them a strong drug candidate. In this study, we assessed the in vitro and in vivo efficacy of lithium complex {[Li(phen)2 sal]} against biofilm-forming MDR A. baumannii. The lithium complex displayed strong antimicrobial activity and reduced the pre-formed mature biofilm which is key barrier for antimicrobial action. Moreover, it employs oxidative stress as one of its mode of actions and causes cellular rupturing. Lithium complex was non-toxic and was significantly effective to overcome pneumonia in mice model. These results highlight the untapped potential of metal complexes that can be explored and utilized for combating notorious A. baumannii infections.

Abstract
Genetic polymorphisms of apolipoprotein B gene (APOB) may result into serum proteomic perturbance in Coronary Artery Disease (CAD). The current case-control cohort of Pakistani subjects was designed to analyze the genetic influence of APOB rs1042031, (G/T) genotype on serum proteome. Subjects were categorized into two groups: CAD patients (n = 480) and healthy individuals (n = 220). For genotyping, tetra ARMS-PCR was carried out and validated through sequencing, whereas LC/MS-based proteomic analysis of serum samples was performed through label-free quantification. In initial step of genotyping, the frequencies of each genotype GG, GT, and TT were 70%, 27%, and 30% in CAD patients, while in control group, the subjects were 52%, 43%, and 5%, respectively, in CAD patients. The genotypic frequencies in patients vs. control groups found significantly different (p = 0.004), and a strong association of dominant alleles GG with the CAD was observed in both dominant (OR: 2.4 (1.71-3.34), p = 0.001) and allelic genetic models (OR: 2.0 (1.45-2.86), p = 0.001). In second step of label-free quantitation, a total of 40 significant proteins were found with altered expression in CAD patients. The enriched Gene Ontology (GO) terms of molecular functions and pathways of these protein showed upregulated pathways as follows: chylomicron remodeling and assembly, complement cascade activation, plasma lipoprotein assembly, apolipoprotein-A receptor binding, and metabolism of fat-soluble vitamins in G allele carrier of rs1042031 (G > T) vs. mutant T-allele carriers. This study provides better understanding of CAD pathobiology by proteogenomics of APOB. It evidences the influence of APOB rs1042031-dominant (GG) genotype with CAD patients.

Abstract
BACKGROUND Homologous recombination repair (HRR) enables fault-free repair of double-stranded DNA breaks. HRR deficiency is predicted to occur in around half of high-grade serous ovarian carcinomas. Ovarian cancers harbouring HRR deficiency typically exhibit sensitivity to poly-ADP ribose polymerase inhibitors (PARPi). Current guidelines recommend a range of approaches for genetic testing to identify predictors of sensitivity to PARPi in ovarian cancer and to identify genetic predisposition. DESIGN To establish a European-wide consensus for genetic testing (including the genetic care pathway), decision making and clinical management of patients with recently diagnosed advanced ovarian cancer, and the validity of biomarkers to predict the effectiveness of PARPi in the first-line setting. The collaborative European experts' consensus group consisted of a steering committee (n = 14) and contributors (n = 84). A (modified) Delphi process was used to establish consensus statements based on a systematic literature search, conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. RESULTS A consensus was reached on 34 statements amongst 98 caregivers (including oncologists, pathologists, clinical geneticists, genetic researchers, and patient advocates). The statements concentrated on (i) the value of testing for BRCA1/2 mutations and HRR deficiency testing, including when and whom to test; (ii) the importance of developing new and better HRR deficiency tests; (iii) the importance of germline non-BRCA HRR and mismatch repair gene mutations for predicting familial risk, but not for predicting sensitivity to PARPi, in the first-line setting; (iv) who should be able to inform patients about genetic testing, and what training and education should these caregivers receive. CONCLUSION These consensus recommendations, from a multidisciplinary panel of experts from across Europe, provide clear guidance on the use of BRCA and HRR deficiency testing for recently diagnosed patients with advanced ovarian cancer.

Abstract
Areca nut or betel nut chewing is most frequently used in Pakistan and is associated with a high risk for oral cancer. Until now, however, there has not been any research conducted on the long-term effect(s) of betel nut chewing on the saliva proteome. In the present study, initially, the changes in the saliva proteome associated with betel nut chewing were investigated. Secondly, the analysis was focused on the changes in salivary proteome with respect to prolonged usage of betel nuts. After extraction, the saliva proteins were digested into peptides and these were subsequently analyzed using mass spectrometry. Data are available via ProteomeXchange with identifier PXD029768. Label-free quantitation of saliva samples revealed a total of 12 proteins that were differentially expressed between betel nut addicts (BNAs), and the control group. The study groups were further divided into three subgroups, the BNA-1, BNA-2, and BNA-3 groups, with respect to the extent of consumption of betel nuts in terms of years. The data analysis revealed a more detailed profiling of proteins expressed after five, ten, and more than ten years of betel nut consumption. A total of 30, 17, and 22 proteins were found to be differentially expressed when divided into the BNA-1, BNA-2, and BNA-3 groups. The present study shows that the chronic usage of betel nuts leads to the expression of proteins, such as SPARC1, profilin, and SBSN, which are known to be involved in head and neck cancers.

Abstract
In the current study, APOB (rs1052031) genotype-guided proteomic analysis was performed in a cohort of Pakistani population. A total of 700 study subjects, including Coronary Artery Disease (CAD) patients (n = 480) and healthy individuals (n = 220) as a control group were included in the study. Genotyping was carried out by using tetra primer-amplification refractory mutation system-based polymerase chain reaction (T-ARMS-PCR) whereas mass spectrometry (Orbitrap MS) was used for label free quantification of serum samples. Genotypic frequency of GG genotype was found to be 90.1%, while 6.4% was for GA genotype and 3.5% was for AA genotypes in CAD patients. In the control group, 87.2% healthy subjects were found to have GG genotype, 11.8% had GA genotype, and 0.9% were with AA genotypes. Significant (p = 0.007) difference was observed between genotypic frequencies in the patients and the control group. The rare allele AA was found to be strongly associated with the CAD [OR: 4 (1.9-16.7)], as compared to the control group in recessive genetic model (p = 0.04). Using label free proteomics, altered expression of 60 significant proteins was observed. Enrichment analysis of these protein showed higher number of up-regulated pathways, including phosphatidylcholine-sterol O-acyltransferase activator activity, cholesterol transfer activity, and sterol transfer activity in AA genotype of rs562338 (G>A) as compared to the wild type GG genotype. This study provides a deeper insight into CAD pathobiology with reference to proteogenomics, and proving this approach as a good platform for identifying the novel proteins and signaling pathways in relation to cardiovascular diseases.

Abstract
Objective: To determine the molecular strain typing and drug resistance pattern of Salmonella enterica serovar Typhi prevalent in Northwest Pakistan. Methodology: A total of 2,138 blood samples of suspected typhoid patients from Northwest Pakistan were collected followed by identification of Salmonella Typhi through biochemical, serological, and species-specific fliC-d gene amplification. These isolates were typed by variable-number tandem repeat (VNTR) profiling and investigated for drug resistance. Results: The overall prevalence of Salmonella Typhi was found to be 8.8% (n = 189). Thirty different VNTR strain types of Salmonella Typhi were detected and the most prevalent strain types were T1 and T4, whereas T27 was less prevalent strain. Among the 189 isolates 175 (92.5%) isolates were multidrug resistant, whereas 12 (5.8%) isolates were extensively drug resistant. Resistance to imipenem in Salmonella Typhi was not observed. Most of the isolates have genes encoding for resistance to fluoroquinolones, including gyrA (n = 164), gyrB (n = 160), parC (n = 164), parE (n = 160), ac(6')-ib-cr (n = 163), qnrS (n = 15), and qnrB (n = 3). Similarly, chloramphinicol (cat; n = 147), azithromycin (msrA; n = 3), and co-trimoxazole (dfrA7; n = 145) resistance genes were detected among Salmonella Typhi isolates. Conclusion: In this study, T1 and T4 type Salmonella Typhi strains were predominantly prevalent in Northwest Pakistan. Antibiotic resistance among Salmonella Typhi isolates were observed. Findings of the study would be helpful to devise an appropriate antibiotic policy to control the emergence of drug-resistant Salmonella Typhi in Pakistan.

Abstract
This study was designed to investigate the prevalence and associated risk factors of Shigella flexneri isolated from drinking water and retail raw food samples in Peshawar, Pakistan. A total of 1,020 different samples were collected from various areas of Peshawar between January 2016 and May 2017, followed by identification of S. flexneri through biochemical, serological, and 16S rRNA gene sequencing. Potential risk factors associated with the development and spreading of S. flexneri infection were also investigated. Overall, 45 (4.41%) samples were positive for Shigella species. Among these samples, the predominant species was S. flexneri (n = 44) followed by S. boydii (n = 1). Interestingly, S. sonnei and S. dysenteriae isolates were not found in any sample. The isolation rate of S. flexneri in drinking water samples, market raw milk, and fruits/vegetables from Peshawar were 6.47%, 3.5%, and 2.9%, respectively. The phylogenetic reconstruction showed genetic diversity among three clades, as clades I and II have isolates of S. flexneri that were circulating within the drinking water, milk, fruits/vegetables, while clade III isolates were recovered from milk samples. Most of S. flexneri were detected in June to September. Potential risk factors of S. flexneri were water sources contaminated by toilet wastes (p = 0.04), surface water drainage (p = 0.0002), hospital wastes (p = 0.01), unhygienic handling (p < 0.05), and transportation of raw food (p = 0.04). In conclusion, S. flexneri isolates of closely related lineage originating from non-clinical samples might be associated with an increased human risk to shigellosis in Pakistan, as significant numbers of S. flexneri were observed in the drinking water and retail raw food samples. PRACTICAL APPLICATION: This study demonstrated the presence of S. flexneri in drinking water and retail raw food samples which seem to possess a serious threat to public health. Potential sources of food and water contamination should properly be monitored by public health authorities to reduce cases of shigellosis.

Abstract
Beta cell apoptosis induced by proinflammatory cytokines is one of the hallmarks of diabetes. Small molecules which can inhibit the cytokine-induced apoptosis could lead to new drug candidates that can be used in combination with existing therapeutic interventions against diabetes. The current study evaluated several effects of bergenin, an isocoumarin derivative, in beta cells in the presence of cytokines. These included (i) increase in beta cell viability (by measuring cellular ATP levels) (ii) suppression of beta cell apoptosis (by measuring caspase activity), (iii) improvement in beta cell function (by measuring glucose-stimulated insulin secretion), and (iv) improvement of beta cells mitochondrial physiological functions. The experiments were carried out using rat beta INS-1E cell line in the presence or absence of bergenin and a cocktail of proinflammatory cytokines (interleukin-1beta, tumor necrosis factor-alpha, and interferon- gamma) for 48 hr. Bergenin significantly inhibited beta cell apoptosis, as inferred from the reduction in the caspase-3 activity (IC50 = 7.29 ± 2.45 μM), and concurrently increased cellular ATP Levels (EC50 = 1.97 ± 0.47 μM). Bergenin also significantly enhanced insulin secretion (EC50 = 6.73 ± 2.15 μM) in INS-1E cells, presumably because of the decreased nitric oxide production (IC50 = 6.82 ± 2.83 μM). Bergenin restored mitochondrial membrane potential (EC50 = 2.27 ± 0.83 μM), decreased ROS production (IC50 = 14.63 ± 3.18 μM), and improved mitochondrial dehydrogenase activity (EC50 = 1.39 ± 0.62 μM). This study shows for the first time that bergenin protected beta cells from cytokine-induced apoptosis and restored insulin secretory function by virtue of its anti-inflammatory, antioxidant and anti-apoptotic properties. To sum up, the above mentioned data highlight bergenin as a promising anti-apoptotic agent in the context of diabetes.

Abstract
BACKGROUND In recurrent ovarian cancer, poly(ADP-ribose) polymerase (PARP)-inhibiting agents have transformed the treatment of platinum-sensitive disease. New data support use of PARP inhibitors earlier in the treatment algorithm. DESIGN We review results from recent phase III trials evaluating PARP inhibitors as treatment and/or maintenance therapy for patients with newly diagnosed ovarian cancer. We discuss the efficacy and safety of these agents in the all-comer and biomarker-selected populations studied in clinical trials, and compare the strengths and limitations of the various trial designs. We also consider priorities for future research, with a particular focus on patient selection and future regimens for populations with high unmet need. RESULTS Four phase III trials (SOLO-1, PAOLA-1/ENGOT-OV25, PRIMA/ENGOT-OV26 and VELIA/GOG-3005) demonstrated remarkable improvements in progression-free survival with PARP inhibitor therapy (olaparib, niraparib or veliparib) for newly diagnosed ovarian cancer. Differences in trial design (treatment and/or maintenance setting; single agent or combination; bevacizumab or no bevacizumab), patient selection (surgical outcome, biomarker eligibility, prognosis) and primary analysis population (intention-to-treat, BRCA mutated or homologous recombination deficiency positive) affect the conclusions that can be drawn from these trials. Overall survival data are pending and there is limited experience regarding long-term safety. CONCLUSIONS PARP inhibitors play a pivotal role in the management of newly diagnosed ovarian cancer, which will affect subsequent treatment choices. Refinement of testing for patient selection and identification of regimens to treat populations that appear to benefit less from PARP inhibitors are a priority.

Abstract
BACKGROUND Selinexor is an oral inhibitor of the nuclear export protein Exportin 1 (XPO1) with demonstrated antitumor activity in solid and hematological malignancies. We evaluated the efficacy and safety of selinexor in heavily pretreated, recurrent gynecological malignancies. METHODS In this phase 2 trial, patients received selinexor (35 or 50 mg/m2 twice-weekly [BIW] or 50 mg/m2 once-weekly [QW]) in 4-week cycles. Primary endpoint was disease control rate (DCR) including complete response (CR), partial response (PR) or stable disease (SD) ≥12 weeks. Secondary endpoints were progression-free survival (PFS), overall survival (OS) and safety. RESULTS 114 patients with ovarian (N = 66), endometrial (N = 23) or cervical (N = 25) cancer were enrolled. Median number of prior regimens for ovarian, endometrial and cervical cancer was 6 (1-11), 2 (1-5), and 3 (1-6) respectively. DCR was 30% (ovarian 30%; endometrial 35%; cervical 24%), which included confirmed PRs in 8%, 9%, and 4% of patients with ovarian, endometrial, and cervical cancer respectively. Median PFS and OS for patients with ovarian, endometrial and cervical cancer were 2.6, 2.8 and 1.4 months, and 7.3, 7.0, and 5.0 months, respectively. Common Grade 3/4 adverse events (AEs) were thrombocytopenia (17%), fatigue (14%), anemia (10%), nausea (9%) and hyponatremia (9%). Patients with ovarian cancer receiving 50 mg/m2 QW had fewer high-grade AEs with similar efficacy as BIW treatment. CONCLUSIONS Selinexor demonstrated single-agent activity and disease control in patients with heavily pretreated ovarian and endometrial cancers. Side effects were a function of dose level and treatment frequency, similar to previous reports, reversible and mitigated with supportive care.

Abstract
Recorded videos of laparoscopic surgery can be used to audit surgical practice with a view to improve clinical practice and surgical outcomes. The objective was to audit our own practice by reviewing video recordings of laparoscopic cholecystectomies to improve our dissection in Calot's triangle and to prevent gall bladder perforation. We used recorded videos of laparoscopic cholecystectomy. In this study initially one hundred consecutive videos were reviewed for: a) establishment of critical view of safety, b) optimization of critical view of safety by division of cystic artery before cystic duct, c) perforation of gall bladder and d) use of diathermy for cystic artery. This prospective interventional audit was performed in a Civil Hospital, Karachi and Hamdard University Hospital, Karachi, Pakistan from January 2008 to March 2010. Recommendations were made according to published literature to change the practice in these steps of procedures. These recommendations were implemented in practice and the following 100 videos were reviewed for the same criteria to see the impact on clinical practice. In the first group, critical view of safety was established in 91 patients compared with 99 patients in 2nd group (p=0.009), optimization of view was done in 54 and 83 patients respectively (p<001), perforation occurred in 32 and 19 patients respectively (p=0.035) and use of diathermy for cystic artery, which was the routine, was stopped completely in the 2nd group. Audit of recorded videos of laparoscopic cholecystectomy can be used as an effective tool to improve surgical practice for safer and better outcome.

Abstract
Background In the open-label randomized phase III AURELIA trial, adding bevacizumab to chemotherapy for platinum-resistant ovarian cancer (PROC) significantly improved progression-free survival and response rate versus chemotherapy alone, but not overall survival (OS). We explored the effect of bevacizumab use after disease progression (PD) in patients randomized to chemotherapy alone. Patients and methods In AURELIA, 361 women with PROC were randomized to chemotherapy alone or with bevacizumab. Patients initially randomized to chemotherapy were offered bevacizumab after PD. Post hoc analyses assessed efficacy and safety in three subgroups: chemotherapy alone, chemotherapy followed by bevacizumab after PD, and chemotherapy plus bevacizumab at randomization. Results Of the 182 patients randomized to chemotherapy alone, 72 (40%) received bevacizumab after PD and 110 (60%) never received bevacizumab. There were no significant differences in patient and disease characteristics between these subgroups at baseline or the time of PD. Compared with patients never receiving bevacizumab, the risk of death was significantly reduced in patients receiving bevacizumab either upfront with chemotherapy [hazard ratio (HR) = 0.68, 95% confidence interval (CI) 0.52-0.90] or after PD (HR = 0.60, 95% CI 0.43-0.86). The tolerability of bevacizumab was similar with administration upfront or after PD. Conclusions Post-PD bevacizumab use may have confounded OS results in AURELIA. In these exploratory analyses of non-randomized subgroups, bevacizumab use, either with chemotherapy or after PD on chemotherapy alone, improved OS compared with no bevacizumab. Combining bevacizumab with chemotherapy at first appearance of platinum resistance maximises the likelihood of patients receiving this active treatment for PROC. ClinicalTrials.gov: NCT00976911.

Abstract
This manuscript reports the consensus statements regarding recurrent ovarian cancer (ROC), reached at the fifth Ovarian Cancer Consensus Conference (OCCC), which was held in Tokyo, Japan, in November 2015. Three important questions were identified: (i) What are the subgroups for clinical trials in ROC? The historical definition of using platinum-free interval (PFI) to categorise patients as having platinum-sensitive/resistant disease was replaced by therapy-free interval (TFI). TFI can be broken down into TFIp (PFI), TFInp (non-PFI) and TFIb (biological agent-free interval). Additional criteria to consider include histology, BRCA mutation status, number/type of previous therapies, outcome of prior surgery and patient reported symptoms. (ii) What are the control arms for clinical trials in ROC? When platinum is considered the best option, the control arm should be a platinum-based therapy with or without an anti-angiogenic agent or a poly (ADP-ribose) polymerase (PARP) inhibitor. If platinum is not considered the best option, the control arm could include a non-platinum drug, either as single agent or in combination. (iii) What are the endpoints for clinical trials in ROC? Overall survival (OS) is the preferred endpoint for patient cohorts with an expected median OS < or = 12 months. Progression-free survival (PFS) is an alternative, and it is the preferred endpoint when the expected median OS is > 12 months. However, PFS alone should not be the only endpoint and must be supported by additional endpoints including pre-defined patient reported outcomes (PROs), time to second subsequent therapy (TSST), or time until definitive deterioration of quality of life (TUDD).

Abstract
Different landmarks are described in laparoscopic cholecystectomy for correct identification and orientation of structures to make the procedure as safe as possible. Among these one of the important landmarks is cystic lymphnode which always lies lateral to the biliary tree and forms the medial end point of dissection. This study was done to determine frequency of identification of cystic lymph node in our population. This retrospective descriptive study was conducted on 217 patients who underwent laparoscopic cholecystectomy for cholelithiasis from January 2012 to December 2013 over a period of two years in Jamal Noor Hospital and Hamdard University Hospital Karachi. All procedures were recorded and reviewed. Frequency of identification of cystic lymph node was documented in different levels of difficulty and whether it was possible to keep the dissection lateral to lymph node. Difficulty was assessed per-operatively by Cuschieri's scale. During dissection cystic lymph node was identified in 170(78.34%) cases. In majority of patients i.e. 165(97.05%), it was related to cystic artery. In 78(45.88%) patient dissection was possible lateral to lymph node. Cystic lymph node can be identified in majority of patients undergoing laparoscopic cholecystectomy and this identification helps in safe dissection of Calot's triangle. Efforts should be made to remain lateral to lymph node to avoid injuries to hepatic pedicle.

Abstract
The first joint European Society for Medical Oncology (ESMO), European SocieTy for Radiotherapy & Oncology (ESTRO) and European Society of Gynaecological Oncology (ESGO) consensus conference on endometrial cancer was held on 11-13 December 2014 in Milan, Italy, and comprised a multidisciplinary panel of 40 leading experts in the management of endometrial cancer. Before the conference, the expert panel prepared three clinically relevant questions about endometrial cancer relating to the following four areas: prevention and screening, surgery, adjuvant treatment and advanced and recurrent disease. All relevant scientific literature, as identified by the experts, was reviewed in advance. During the consensus conference, the panel developed recommendations for each specific question and a consensus was reached. Results of this consensus conference, together with a summary of evidence supporting each recommendation, are detailed in this article. All participants have approved this final article.

Abstract
To determine the correlation of wound morbidity especially serum drain output in on lay mesh hernioplasty with Body Mass Index (BMI). This prospective descriptive study was conducted at Hamdard University Hospital and Jamal Noor Hospital from January 2010 to December 2011. A total of 42 females with ventral hernias were included. According to BMI, patients were divided in two groups. Group 1(G-1) included patients with BMI ≤29.9 and Group 2(G-2) included patients with BMI ≥30. All patients underwent hernioplasty by conventional open method (on lay technique). Wound was closed over a vaccum drain (16 Fr). Total drain output, the number of days drain kept, clinical seroma formation & need of aspiration after removal of drain, discharge from the wound and wound infection were recorded and analyzed on SPSS version 15 by using sample 't' test. A total of 42 female patients, 21 in each group, were included with the mean age of 46.95 years. Size of hernial defect was 4.80cm in G-1 and 4.61cm in G-2. Mean drain out- put in G-1 was 134.05ml while in G-2 it was 244.29ml (p=0.008). Duration of drainage in G-1 was 3.71 days and in G-2 was 5.24 days (p=0.028). Seroma formation and serous discharge from the wound occurred in 2(4.76%) patients, both were from Group-1 and they required aspiration once only. Wound infection occurred in 4(9.52%) patients, and all were in Group 2. Post operative drain output in on lay mesh hernioplasty is directly proportional to the Body Mass Index (BMI) and these are the patients who require a longer period of drainage therefore this fact should be explained to obese patients in pre operative informed consent.

Abstract
This study was done to evaluate the frequency of iatrogenic gall bladder perforation (IGBP) in laparoscopic cholecystectomy and to determine its association with gender, adhesions in right upper quadrant and types of gall bladder. This retrospective descriptive study included 200 patients who underwent laparoscopic cholecystectomy for symptomatic cholelithiasis at Jamal Noor Hospital and Hamdard University Hospital, Karachi from January 2007 to January 2009. Video recording of all 200 laparoscopic cholecystectomies were analyzed for the IGBP. The different factors; sex of the patient, type of gall bladder, presence of adhesions in the right upper quadrant, timing of perforation, site of perforation, cause of perforation and spillage of stones were recorded. Data was entered and analyzed on SPSS 15. Pearson Chi Square test was applied to check the significance of these factors in IGBP where applicable. In this study there were 173 females and 27 male patients. IGBP occurred in 51 patients (25.5%) and among them 40(23.12%) were females and 11(40.74%) males. Statistical analysis failed to prove male gender a significant factor in the IGBP (p=0.051). Spillage of stones occurred in 23 patients (11.5% in total study population). In 32(18.49%) patients with chronic calculus cholecystitis IGBP occured while in other cluster of 27 patients suffering from acute cholecystitis, empyema & mucocele, 19(70.37%) had IGBP. Hence the condition of gall bladder (acute cholecystitis, empyema and mucocele) was proved statistically a significant factor in IGBP (p=0.000). Adhesiolysis in right upper quadrant was required in 109 patients in whom 31 patients (28.44%) had IGBP while in 91 patients in whom no adhesiolysis was required, 20 patients (21.98%) had IGBP. Statistically no significant difference was present regarding this factor (p=0.296). In total of 51 patients of IGBP, fundus of gall bladder was the commonest site of perforation in 21(41.18%), followed by body of gall bladder in 18(35.29%) and Hartman's pouch in 12(23.53%) patients. In 27(52.94%) patients, diathermy hook was the cause of perforation followed by grasping forceps in 24(47.06%) patients. In 33(64.71%) patients perforations occurred during dissection of gall bladder from liver bed, in 2(3.92%) during adhesiolysis and in 16(31.37%) during retraction maneuvers. Perforation of gall bladder occurred in 25.5% of patients during laparoscopic cholecystectomy and acutely inflamed and over distended gall bladders were proved significant factor for this intraoperative event.

Abstract
The study was done, to determine the factors for negative appendicectomies. This prospective descriptive study includes patients managed at four non teaching and a teaching hospital of Karachi from March 2006 to February 2008. One hundred and sixty eight patients underwent appendicectomy during the study period. Details of clinical presentations, investigations, operative findings and histopathology were entered and analyzed. Literature search was aimed to see the negative appendicectomy rate (NAR) in last ten years despite using diagnostic tools (clinical scoring, diagnostic imaging and laparoscopy). In this study a total number of 168 patients under went appendicectomy. Normal appendices were found in 31 patients (negative appendicectomy rate was 18.45%) and associated pathology was seen in 13 patients, an incidental finding of Meckel's diverticulum in 5 patients and no other pathology was seen in 13 patients. The different factors which we identified for negative appendicectomies in our practice were non teaching hospitals where diagnostic scoring system was difficult to apply, female gender, selective use of imaging modality, other pathologies presenting with pain in right lower quadrant (RLQ) and requiring surgical intervention, and non-availability of CT scan and laparoscopy. Despite many advances in diagnostic system, acute appendicitis is still a diagnostic dilemma at times. Although there is no substitute for clinical judgment but in sub groups of patients in whom the possibility of negative appendicectomy is high, diagnostic modalities should be used judiciously to decrease the negative exploration.

Abstract
The objective of this study was to compare the safety and efficacy of carboplatin plus epirubicin and paclitaxel (TEC) to carboplatin and paclitaxel (TC), in the treatment of epithelial ovarian, peritoneal, or tubal carcinoma. Between March 1999 and August 2001, 887 patients were randomized to receive six to nine cycles of paclitaxel (175 mg/m2, 3 h intravenously) followed by carboplatin (AUC 5, Calvert formula) with or without epirubicin (75 mg/m2 intravenously prior to paclitaxel), on a 3-weekly schedule. The primary endpoint was progression-free survival. Demographic information: Residual disease <1 cm was reported on 41% of patients. At the end of treatment, 65% in the TEC and 55% in the TC arm had achieved a clinical complete response, and 18 and 25% a clinical partial response resulting in an overall response rate of 83% in the TEC and 80% in the TC arm, whereas 7 and 9% had progressive disease, respectively. The three-drug combination produced a markedly higher myelotoxicity, resulting in a higher frequency of febrile neutropenia (12.5% of the TEC and 1.5% of the TC patients) and a higher number of dose reductions and treatment delays. Cycle prolongation above seven days was seen in 7 and 5% of cycles in the TEC and TC arm, respectively. Stomatitis > or = grade 3 was also higher with TEC (4% TEC and 0.5% TC). Reductions in left ventricular ejection fraction of more than 15% after six courses were slightly more common with the TEC regimen (3% versus 1.5%), but the difference was not statistically significant (P = 0.2). In conclusion, treatment with the TEC combination produced a higher rate of complete responses than treatment with the TC combination. Toxicity was manageable. Long-term survival data are awaited.

Abstract
OBJECTIVES To investigate attitudes to clinical research amongst cancer trial participants and nonparticipants, and to compare results with those from previous studies amongst participants in noncancer trials. DESIGN Trial participating respondents were given three questionnaires during the clinical trials. Respondents amongst patients declining randomization answered a single questionnaire. SETTING Participants and nonparticipants in randomized clinical cancer trials. SUBJECTS Forty-one participants and 47 nonparticipants in cancer trials. RESULTS Altruistic motives of physicians to conduct medical research were highly rated. Attitudes towards clinical research were positive in all groups, with nonparticipant respondents being the least positive. Eight to nine tenths found scientific testing necessary before general health service implementation. Trial participants were, as compared with nonparticipating respondents, more positive towards both participation of self and others. Both personal and altruistic motives for participation were highly rated. Primary reasons for nonparticipation were fear of 'the unknown' and/or unease with randomization. Only a minority felt a moral problem created by declining trial participation. Respondents amongst noncancer participants were more satisfied with the information given than both cancer participants and cancer nonparticipants. Negative experiences in cancer participants generally dealt with frustration related to seeing too many physicians at check-up appointments. CONCLUSION Attitudes towards clinical research are generally positive even in cancer nonparticipants. Both personal and altruistic motives for participation were highly rated. A fear of 'the unknown' and resentments towards randomization were primary reasons to renounce participation. Seeing too many physicians at check-up appointments seems to be an important factor for negative experiences in cancer trial participants.

Abstract
Suramin inhibits the growth of non-small cell lung cancer (NSCLC) and breast cancer in vitro by blocking the action of most known growth factors. The clinical efficacy of suramin was evaluated in patients with unresectable or relapsed NSCLC (n = 16) and advanced breast cancer (ABC) resistant to conventional therapies (n = 12). A plasma level > or = 200 micrograms/ml was maintained by three times weekly administrations using adaptive control with feedback. Treatment was continued until documented progression of disease or unacceptable toxicity. No clinical responses were observed in any patient. Median overall survival was 4.5 months in NSCLC and 9 months in ABC patients. Mean treatment duration was 6.6 weeks in NSCLC patients and 15.9 weeks in ABC patients. Treatment was discontinued due to disease progression in 14 patients, unacceptable adverse effects in 11 patients, while three patients refused to continue therapy. We cannot recommend this drug for further clinical trials in NSCLC and ABC.

Abstract
The purpose of this study was to determine the maximal tolerable dose (MTD) of epirubicin and ADR-529 given in combination with cyclophosphamide, 5-fluorouracil, and tamoxifen. A total of 64 breast cancer patients with locally advanced disease or a first metastatic event were included. Using fixed doses of cyclophosphamide, 5-fluorouracil, and tamoxifen, cohorts of ten patients were treated with escalating doses of epirubicin and ADR-529. With the use of protocol criteria specifying evaluation after the first course, the MTD was not reached. Dose reductions carried out due to hematologic toxicity during the first four courses made it impossible to escalate doses of epirubicin beyond 80 mg/m2 given together with ADR-529 600 mg/m2. The vascular toxicity of ADR-529 necessitated central venous access in a number of patients. For phase III evaluation of ADR-529 given together with cyclophosphamide, epirubicin, 5-fluorouracil, and tamoxifen (CEF/TAM) we recommend using epirubicin/ADR-529 at 60/600 mg/m2. Together with evaluation of the cardioprotective properties of ADR-529, we recommend evaluating the impact of ADR-529 on the efficacy of cytotoxic therapy and investigating further the toxicity of ADR-529.

Abstract
A high-pressure liquid chromatographic method for determination of the bisdioxopiperazine derivative ADR-529 (ICRF-187), a compound proven effective in protection against anthracycline-induced cardiotoxicity, has been developed. The limit of quantitation was 5 ng/ml using a narrow-bore 5-microns silica column and UV detection. The method was used for determination of pharmacokinetic profiles of ADR-529 after a 3-weekly i.v. administration of different doses of ADR-529 (600-1000 mg/m2) together with different doses of epirubicin (E, 60-100 mg/m2), fixed-dose cyclophosphamide (C, 600 mg/m2), fixed-dose 5-fluorouracil (F, 600 mg/m2), and daily administration of tamoxifen (T, 30 mg; CEF-T) in the treatment of patients with metastatic breast cancer. Pharmacokinetic parameters for epirubicin were also determined. The aim of the study was to determine (1) whether the pharmacokinetics of ADR-529 as part of a combination with CEF-T changes with increasing doses of ADR-529 and increasing doses of epirubicin and (2) whether the pharmacokinetics of epirubicin in the same combinations is altered with the administration of increasing doses of ADR-529. A total of 82 patients were included. A crossover study including 16 of the patients showed no significant difference in epirubicin pharmacokinetic parameters when epirubicin was given with or without concomitant administration of ADR-529. Apart from minor changes in the distributional half-lives, the pharmacokinetic parameters of epirubicin were not altered with increasing doses of ADR-529, nor were the pharmacokinetic parameters of ADR-529 itself. Escalating doses of epirubicin did not significantly alter the pharmacokinetic parameters of ADR-529 with the exception of a 30% increase in the terminal half-life and a decrease in total body clearance when the epirubicin dose was raised from 60 to 100 mg/m2. We conclude that concomitant administration of ADR-529 does not alter the distribution and elimination of epirubicin in doses suitable for preventing the anthracycline-induced cardiotoxicity.

Abstract
Estrogen receptor-negative human breast cancer is usually an aggressive, hormone independent tumour. Recent studies show that growth of these tumours could be influenced by anti-estrogens. Anti-estrogens appear to stimulate the production of Transforming Growth Factor-beta (TGF-beta) in hormone dependent as well as independent cell lines suggesting as a result inhibition of cellular proliferation of these cell lines by TGF-beta through an autocrine/paracrine mechanism.

Abstract
Seventy-two patients with recurrent or refractory malignant lymphoproliferative diseases were treated with MIME combination chemotherapy (methyl-GAG, ifosfamide, methotrexate, etoposide) and concurrent mesna to prevent urothelial toxicity; 41 patients had high/intermediate-grade non-Hodgkin's lymphoma (NHL), 18 low-grade NHL/chronic lymphocytic leukemia (CLL), and 13 Hodgkin's disease (HD). The overall response rates were 56% in high/intermediate-grade NHL, 11% in low-grade NHL/CLL, and 69% in HD respectively. Median survival in the same 3 groups was 7, 2 and 10 months respectively. Neither previous type of response to chemotherapy nor previous amount of treatment predicted the outcome of MIME chemotherapy. Toxicity was modest, hemorrhagic cystitis did not occur, and only one therapy-related death occurred. Although MIME appears to be a safe treatment with considerable activity in recurrent or refractory lymphoproliferative disease very few patients become long-term survivors. However, MIME is well suited for remission induction in patients intended for subsequent autologous bone-marrow transplantation.
