RESUMEN

The European Society of Gynaecological Oncology, the European Society for Medical Oncology (ESMO) and the European Society of Pathology held a consensus conference (CC) on ovarian cancer on 15-16 June 2022 in Valencia, Spain. The CC panel included 44 experts in the management of ovarian cancer and pathology, an ESMO scientific advisor and a methodologist. The aim was to discuss new or contentious topics and develop recommendations to improve and harmonise the management of patients with ovarian cancer. Eighteen questions were identified for discussion under four main topics: (i) pathology and molecular biology, (ii) early-stage disease and pelvic mass in pregnancy, (iii) advanced stage (including older/frail patients) and (iv) recurrent disease. The panel was divided into four working groups (WGs) to each address questions relating to one of the four topics outlined above, based on their expertise. Relevant scientific literature was reviewed in advance. Recommendations were developed by the WGs and then presented to the entire panel for further discussion and amendment before voting. This manuscript focuses on the recommendation statements that reached a consensus, their voting results and a summary of evidence supporting each recommendation.

RESUMEN

BACKGROUND: The study aims to understand system barriers to research participation for people with intellectual disabilities. METHODS: A mixed-methods approach examined the inclusivity of people with intellectual disabilities (IDs) in a random sample of National Institute for Health and Care Research (NIHR) studies conducted in 2019-2020. An online questionnaire (stage 1) was sent to the selected studies lead investigators. An expert by experience panel of 25 people with intellectual disabilities (IDs, stage 2), discussed the stage 1 feedback. Descriptive statistics for quantitative data and thematic analysis for qualitative data was conducted. RESULTS: Of 180 studies reviewed, 131 studies (78%) excluded people with IDs. Of these, 45 (34.3%) study researchers provided feedback. Seven (20%) of the 34 studies which included people with IDs gave feedback. Of all respondents over half felt their study had some relevance to people with IDs. A minority (7.6%) stated their study had no relevance. For a quarter of respondents (23.5%), resource issues were a challenge. Qualitative analysis of both stages produced four overarching themes of Research design and delivery, Informed consent, Resource allocation, and Knowledge and skills. CONCLUSION: Health research continues to exclude people with IDs. Researchers and experts by experience identified non-accessible research design, lack of confidence with capacity and consent processes, limited resources such as time and a need for training as barriers. Ethics committees appear reluctant to include people with cognitive deficits to 'protect' them. People with IDs want to be included in research, not only as participants but also through coproduction.

RESUMEN

BACKGROUND: Worldwide there are concerns about the supply of nurses into health systems. Understanding and balancing the supply of and demand for healthcare professionals is crucial to efficient healthcare delivery, yet there is relatively little research that examines in detail where nursing students come from and where they go after qualification. OBJECTIVES: To investigate the demographic characteristics of applicants to nursing and midwifery programmes in England, those that are enrolled, attrition during study, and their career intentions on graduation. METHODS: A descriptive case study was conducted in south west England drawing on a complementary set of analyses of routinely collected application and enrolment data from 2017-2020. These were augmented by derivation of student deprivation indices and a follow-up study of nursing and midwifery students qualifying between May 2020 and April 2021. RESULTS: The percentage of males applying for nursing doubled and the mean age of all enrolled students (except midwifery) increased during the study period. The mean level of deprivation of applicants increased from the 51st to the 55th centile indicating widening of participation. Most applying and enrolled students originated from the same region as the nursing school and remained working there on qualification. Successively more males than females were lost from the system at each stage from application to qualification. Qualifying students most common job choice was within acute Trusts, with Medical, District nursing and surgical being the most common choices. The most important factors regarding job choice were location, the characteristics of the Trust, having been there as a student, and family considerations. CONCLUSIONS: The data provide useful information on the nursing educational pipeline. The data discussed here raise questions that would benefit from further regional and national empirical research.

RESUMEN

In this study, an endophytic Bacillus sp. strain (K7) was isolated from the medicinally important ornamental plant, Jasminum officinale. Biochemical analyses were conducted to evaluate the nature of the extracted product, which displayed strong anticandidal activity against Candida albicans (CA) SC5314, as evident from the results obtained in agar-cup diffusion tests, phase-contrast microscopy, scanning electron microscopy and minimum inhibitory concentration assays. After confirming the presence of the gene clusters encoding the lipopeptides iturins and fengycin in the genome of K7, their corresponding molecular ions were identified using MALDI-TOF-MS. 3D structures of the lipopeptides were downloaded from specific databases and molecular docking was performed against a vital CA enzyme, exo-1,3-beta-glucanase, involved in cell wall remodelling, adhesion to polymer materials and biofilm formation. The docking score of iturins was found to be -8·6 and -8·2 kcal mol-1 and for fengycin it was -9·4 kcal mol-1 , indicating a strong affinity of these cyclic lipopeptides towards exo-1,3-beta-glucanase. The combined in vitro and in silico anticandidal studies suggested that these secreted lipopeptides from Bacillus sp. may be used as potential therapeutics against opportunistic and complicated infections of CA.

RESUMEN

Chronic obstructive pulmonary disease (COPD) is a significant health burden and is one of the leading causes of death having rising mortality rate in developed and developing countries. Cardiac troponin t (cTnT) is an established myocardial injury marker and not only increases in flow- limiting coronary artery stenosis or occlusion of coronary arteries but also in pulmonary embolism, septic shock, heart failure and stroke. The positive association between elevation of cTnT and neutrophils due to exaggerated inflammatory response leading to myocardial injury and increased cTnT can have prognostic value in acute exacerbation of COPD. Material: The present study was conducted with the aim of predicting the severity of COPD exacerbation based on level of cardiac TnT. 85 patients with a diagnosis of COPD age more than 20 years admitted in general medicine wards in SMS medical college during 2020 were enrolled in this study. Spirometry and Chest Xray were used in diagnosing COPD. Troponin T level was measured within 1 hour of admission. Severity of the exacerbation was estimated by PaO2 & PaCO2 levels and need for assisted ventilation. Observation: Here, in our study 43.53% cases has troponin-T elevated. And amongst those with Trop T elevated 82.4% needed assisted ventilation compared to 24.6 % patients with normal Trop T needing assisted ventilation indicating significant positive correlation of Trop t level with need for assisted ventilation in acute exacerbation of COPD. Amongst those with elevated Trop T, mean oxygen saturation was77.97 % and mean pco2 was 73%. Whilst those with normal troponin T level they had mean oxygen saturation of 86% and mean co2 level of 42% indicating that those with elevated cardiac Trop T has more severe hypoxia and more severe hypercapnia compared to those with normal cardiac Trop T level implying significant positive association of elevated Trop T level with severity of COPD exacerbation Conclusion: This observation implies there is a positive correlation of elevated trop T level and severity of acute exacerbation of COPD in terms of need for assisted ventilation, severity of hypoxia and hypercapnia .So assessment of Trop T level in acute exacerbation of COPD will be having prognostic benefit and can be used for assessing course of the disease along with better management of the patients.

RESUMEN

Cardiomyopathies are a heterogeneous group of diseases predominantly affecting the heart muscle and often lead to progressive heart failure-related disability or cardiovascular death. Hypertrophic cardiomyopathy (HCM) is a cardiac muscle disorder mostly caused by the mutations in genes encoding cardiac sarcomere. Germ-line mutations in MYBPC3 causes hypertrophic cardiomyopathy (HCM). However, most of the HCM associated MYBPC3 mutations were truncating mutations. Extreme phenotypic heterogeneity was observed among HCM patients with MYBPC3 mutations. In this study, we investigated a Chinese man who presented with HCM. Whole exome sequencing identified a novel heterozygous deletion (c.3781_3785delGAGGC) in exon 33 of the MYBPC3 in the proband. This heterozygous variant causes frameshift (p.Glu1261Thrfs*3), which predicted to form a truncated MYBPC3 protein. The proband's father also carries this variant in a heterozygous state while the proband's mother did not harbor this variant. Here, we report on a novel deletion in the MYBPC3 gene associated with HCM. We also highlight the importance of whole exome sequencing for molecular diagnosis for the patients with familial HCM.

RESUMEN

BACKGROUND: Mirvetuximab soravtansine (MIRV) is an antibody-drug conjugate comprising a folate receptor alpha (FRα)-binding antibody, cleavable linker, and the maytansinoid DM4, a potent tubulin-targeting agent. The randomized, open-label, phase III study FORWARD I compared MIRV and investigator's choice chemotherapy in patients with platinum-resistant epithelial ovarian cancer (EOC). PATIENTS AND METHODS: Eligible patients with 1-3 prior lines of therapy and whose tumors were positive for FRα expression were randomly assigned, in a 2 : 1 ratio, to receive MIRV (6 mg/kg, adjusted ideal body weight) or chemotherapy (paclitaxel, pegylated liposomal doxorubicin, or topotecan). The primary endpoint was progression-free survival [PFS, Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, blinded independent central review] in the intention-to-treat (ITT) population and in the prespecified FRα high population. RESULTS: A total of 366 patients were randomized; 243 received MIRV and 109 received chemotherapy. The primary endpoint, PFS, did not reach statistical significance in either the ITT [hazard ratio (HR), 0.98, P = 0.897] or the FRα high population (HR, 0.69, P = 0.049). Superior outcomes for MIRV over chemotherapy were observed in all secondary endpoints in the FRα high population including improved objective response rate (24% versus 10%), CA-125 responses (53% versus 25%), and patient-reported outcomes (27% versus 13%). Fewer treatment-related grade 3 or higher adverse events (25.1% versus 44.0%), and fewer events leading to dose reduction (19.8% versus 30.3%) and treatment discontinuation (4.5% versus 8.3%) were seen with MIRV compared with chemotherapy. CONCLUSIONS: In patients with platinum-resistant EOC, MIRV did not result in a significant improvement in PFS compared with chemotherapy. Secondary endpoints consistently favored MIRV, particularly in patients with high FRα expression. MIRV showed a differentiated and more manageable safety profile than chemotherapy.

RESUMEN

We describe an analysis comparing the pp[over ¯] elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sections, extrapolated to a center-of-mass energy of sqrt[s]=1.96 TeV, are compared with the D0 measurement in the region of the diffractive minimum and the second maximum of the pp cross section. The two data sets disagree at the 3.4σ level and thus provide evidence for the t-channel exchange of a colorless, C-odd gluonic compound, also known as the odderon. We combine these results with a TOTEM analysis of the same C-odd exchange based on the total cross section and the ratio of the real to imaginary parts of the forward elastic strong interaction scattering amplitude in pp scattering for which the significance is between 3.4σ and 4.6σ. The combined significance is larger than 5σ and is interpreted as the first observation of the exchange of a colorless, C-odd gluonic compound.

RESUMEN

BACKGROUND: Aromatase inhibitors have been used empirically to treat a subset of patients with hormone receptor positive uterine leiomyosarcomas(LMS) and carcinosarcomas (UCS) mainly supported by retrospective data. We evaluated the activity of anastrozole in two rare cohorts; patients with recurrent/metastatic LMS and UCS enrolled in PARAGON, a basket trial of anastrozole in estrogen receptor (ER+)/progesterone receptor positive (PR+) gynecological cancers. METHOD: An investigator-initiated, single-arm, prospective open-label trial of anastrozole 1 mg/day in patients with ER &/or PR + ve LMS or UCS with measurable disease, treated until progression or unacceptable toxicity. Primary endpoint was clinical benefit (complete/partial response + stable disease) rate (CBR) at 3 months. Secondary endpoints include progression-free survival (PFS), quality of life and toxicity. RESULTS: 39 eligible patients were enrolled, 32 with LMS and 7 with UCS. For the LMS cohort CBR at 3 months was 35% (95% CI: 21-53%) with a median duration of clinical benefit of 5.8 months. Best response was a partial response in one patient. Two patients remained on treatment for more than one year. The median progression-free survival was 2.8 months (95% CI: 2.6-4.9). For the UCS cohort CBR at 3 months was 43% (95% CI: 16-75%) with a median duration of clinical benefit of 5.6 months. Stable disease was seen in 3 patients but no objective responses were seen. The median progression-free survival was 2.7 months (95% CI, 1.1-8.2). Safety was acceptable with 5/39 evaluable patients showing grade 3 toxicities. CONCLUSION: Whilst objective response rates with anastrozole are low, the clinical benefit rate and good tolerance suggests that aromatase inhibitor therapy may have a role in a subset of patients with metastatic LMS and UCS.

RESUMEN

BACKGROUND: Aromatase inhibitors are standard of care for low-grade endometrial stromal sarcomas (LGESS), based on very high response rates reported in retrospective studies. We evaluated the activity of anastrozole in recurrent/metastatic LGESS patients enrolled in PARAGON, a basket trial of anastrozole in estrogen receptor (ER±)/progesterone receptor (PR+) gynecological cancers. METHOD: An investigator-initiated, single-arm, prospective open-label trial of anastrozole 1 mg/day in patients with ER ± PR + ve LGESS with measurable disease, treated until progressive disease or unacceptable toxicity. Primary endpoint was clinical benefit (complete/partial response + stable disease) rate (CBR) at 3 months. Secondary endpoints include progression-free survival (PFS), quality of life and toxicity. RESULTS: 15 eligible patients were enrolled. CBR at 3 months was 73% (95% CI: 48-89.1%); unchanged at 6 months. Best response was 26.7%, including complete response in one (6.7%; 95% CI 1.2-29.8%), partial response in three (20%, 95% CI 7.1-45.2%) and stable disease in seven (46.7%). Four patients ceased treatment by 3 months due to progression. Median PFS was not reached (25th percentile: 2.9 months (95% CI: 1.2-NR)). PFS was 73.3%, 73.3% and 66% at 6, 12, and 18 months, respectively. Six patients remained on treatment for an average of 44.2 months (range 34.5-63.6) up until data cut. Toxicity was as expected, with 3 patients stopping due to adverse effects. CONCLUSION: The 26.7% objective response rate with anastrozole is lower than reported in retrospective series, but the CBR was high and durable. The results underscore the importance of prospective trials in rare cancers.

RESUMEN

Imaging surface deformation of a coupon specimen in microtensile testing with an optical microscope presents challenges due to the narrow depth of field (DoF) of optical microscopes. Materials being heterogeneous at microscopic length scale, the sample surface deforms into a complex 3D surface texture, evolving continuously as the loading increases. Because of the narrow DoF, the region that is in focus within the field of view (FoV) decreases substantially in size with the increasing out-of-plane heterogeneous deformation. To address this challenge, a method based on image blending and stabilisation of the captured image frames is proposed. Image blending combines the partial regions that are in focus from a set of successive image frames captured at different working distances from the object surface plane to construct a single image that has a large part of the FoV in focus. The blended images are then obtained at different levels of macroscopic strains, that is the global homogeneous strain, in order to characterise the evolution of the heterogeneous deformation. The image stabilisation removes any misalignments of the blended images by spatially realigning them choosing a common feature as a reference point. The validation of the proposed method with conventionally and additively manufactured stainless steel 316L (SS 316L) specimens demonstrates excellent improvement in image quality. Almost 100% of the FoV is maintained in focus regardless of the amount of out-of-plane heterogeneous deformation caused during tensile testing, which is quite remarkable for optical microscopy imaging. Consequently, the blended and stabilised images enhanced the accuracy of digital image correlation (DIC). Time-lapse videos of the deformation generated using these images captured the evolution of the slip bands and their transmission through twinning boundaries in the stainless steel microstructure. Overall, this study demonstrates the feasibility of using image-processing techniques to advance optical microscopy to image complex 3D surfaces evolving with time.

RESUMEN

BACKGROUND: Symptomatic haemorrhoids affect a large number of patients throughout the world. The aim of this systematic review was to compare the surgical outcomes of stapled haemorrhoidopexy (SH) versus open haemorrhoidectomy (OH) over a 20-year period. METHODS: Randomized controlled trials published between January 1998 and January 2019 were extracted from Pubmed using defined search criteria. Study characteristics and outcomes in the form of short-term and long-term complications of the two techniques were analyzed. Any changes in trend of outcomes over time were assessed by comparing article groups 1998-2008 and 2009-2019. RESULTS: Twenty-nine and 9 relevant articles were extracted for the 1998-2008 (period 1) and 2009-2019 (period 2) cohorts, respectively. Over the two time periods, SH was found to be a safe procedure, associated with statistically reduced operative time (in 13/21 studies during period 1 and in 3/8 studies during period 2), statistically less intraoperative bleeding (3/7 studies in period 1 and 1/1 study in period 2) and consistently less early postoperative pain on the visual analogue scale (12/15 studies in period 1 and 4/5 studies in period 2) resulting in shorter hospital stay (12/20 studies in period 1 and 2/2 studies in period 2) at the expense of a higher cost. In the longer term, although chronic pain in SH and OH patents is comparable, patient satisfaction with SH may decline with time and at 2-year follow-up OH appeared to be associated with greater patient satisfaction. CONCLUSIONS: SH appears to be safe with potential advantages, at least in the short term, but the evidence is lacking at the moment to suggest its routine use in clinical practice.

RESUMEN

We established an international consortium to review and discuss relevant clinical evidence in order to develop expert consensus statements related to cancer management during the severe acute respiratory syndrome coronavirus 2-related disease (COVID-19) pandemic. The steering committee prepared 10 working packages addressing significant clinical questions from diagnosis to surgery. During a virtual consensus meeting of 62 global experts and one patient advocate, led by the European Society for Medical Oncology, statements were discussed, amended and voted upon. When consensus could not be reached, the panel revised statements until a consensus was reached. Overall, the expert panel agreed on 28 consensus statements that can be used to overcome many of the clinical and technical areas of uncertainty ranging from diagnosis to therapeutic planning and treatment during the COVID-19 pandemic.

RESUMEN

BACKGROUND: We investigated the safety and efficacy of a combination of the oral tyrosine kinase inhibitor, nintedanib (BIBF 1120) with oral cyclophosphamide in patients with relapsed ovarian cancer. PATIENTS AND METHODS: Patients with relapsed ovarian, fallopian tube or primary peritoneal cancer received oral cyclophosphamide (100 mg o.d.) and were randomised (1,1) to also have either oral nintedanib or placebo. The primary endpoint was overall survival (OS). Secondary endpoints included progression free survival (PFS), response rate, toxicity, and quality of life. RESULTS: 117 patients were randomised, 3 did not start trial treatment, median age 64 years. Forty-five (39%) had received ≥5 lines chemotherapy. 30% had received prior bevacizumab. The median OS was 6.8 (nintedanib) versus 6.4 (placebo) months (hazard ratio 1.08; 95% confidence interval 0.72-1.62; P = 0.72). The 6-month PFS rate was 29.6% versus 22.8% (P = 0.57). Grade 3/4 adverse events occurred in 64% (nintedanib) versus 54% (placebo) of patients (P = 0.28); the most frequent G3/4 toxicities were lymphopenia (18.6% nintedanib versus 16.4% placebo), diarrhoea (13.6% versus 0%), neutropenia (11.9% versus 0%), fatigue (10.2% versus 9.1%), and vomiting (10.2% versus 7.3%). Patients who had received prior bevacizumab treatment had 52 days less time on treatment (P < 0.01). 26 patients (23%) took oral cyclophosphamide for ≥6 months. There were no differences in quality of life between treatment arms. CONCLUSIONS: This is the largest reported cohort of patients with relapsed ovarian cancer treated with oral cyclophosphamide. Nintedanib did not improve outcomes when added to oral cyclophosphamide. Although not significant, more patients than expected remained on treatment for ≥6 months. This may reflect a higher proportion of patients with more indolent disease or the higher dose of cyclophosphamide used. CLINICAL TRIAL REGISTRATION: Clinicaltrials.govNCT01610869.

RESUMEN

OBJECTIVES: 'Dementia Friends' is a programme used to raise awareness of dementia, developed by the Alzheimer's Society, which has been delivered across the UK to diverse populations, including adolescents. However, there is little evidence available with regards to adolescents' perceptions of the programme and its impact. This study aims to explore this in a group of adolescents from the south of England. STUDY DESIGN: Focus group discussions. METHODS: Thirty adolescents aged between 11 and 16 years were recruited from two schools in East Sussex, England. All had participated in a Dementia Friends session in the past month. Focus group discussions were transcribed, coded and themes were created using inductive thematic analysis. RESULTS: Four themes were identified: (1) perceptions and experiences of dementia, (2) outcomes and learning from Dementia Friends session, (3) reactions to the Dementia Friends session and (4) identified future learning needs. CONCLUSIONS: Adolescents had generally positive opinions about Dementia Friends, particularly the interactive nature of the session. Whilst they felt participating in Dementia Friends improved their attitudes and knowledge, they were often left wanting to learn more. Future research needs to empirically evaluate the extent to which Dementia Friends may improve attitudes and knowledge of dementia.

RESUMEN

OBJECTIVE: The present study was undertaken to evaluate prognostic relevance of select circulating immune mechanistic biomarkers in COVID-19 positive patients for early identification and categorization of symptomatic patients who would need critical care with consequent adequate and optimal resource allocation and definitive management protocol. MATERIALS AND METHODS: The present retrospective observational study, on 35 symptomatic and 35 asymptomatic patients, was carried out in SMS Medical College and Hospital, Jaipur comparatively assessing epidemiological history, clinical features and laboratory investigations. RESULTS: During the course of study, 35 symptomatic and 35 asymptomatic patients were assessed. All the patients were of Indian ethnicity and had a history of contact with a COVID 19 positive case. Male patients constituted of 67 % of the population. The median age of patients in symptomatic and asymptomatic group was 60 years and 30 years, respectively. Out of the 70 patients studied, 47 (67%) patients recovered and were discharged whereas 23 (32.8 %) succumbed to the disease process. Lymphopenia was observed in 80% of symptomatic patient population, though only 11.5% of asymptomatic patients documented lymphopenia. Among the patients who died of COVID 19 (n=23), lymphopenia was observed in 18 (82%) patients, with moderate lymphopenia present in 13 (59 %) and severe lymphopenia present in 5 (22.7%) patients. Neutrophilia was observed across both category of patients, symptomatic and asymptomatic. Neutrophilia featured prominently in the symptomatic COVID-19 group with a median nadir in ALC of 7 × 109/L as compared to that of 3.8 × 109/L so observed in asymptomatic sample population. Red cell distribution width was slightly raised in both groups with a median RDW of 15.3% in COVID 19 patients which was raised as compared to that observed in normal population (range: 12.8 ± 1.2 %). CONCLUSION: Lymphopenia is an effective and reliable indicator of onset of symptoms and severity of disease in COVID-19 patients. RDW was found to be higher in COVID 19 patients in comparison to normal patients, however it had no significant relationship with appearance of symptoms or severity of the disease.

RESUMEN

PURPOSE: The present study was undertaken to investigate epidemiological distribution, clinical manifestation, co morbid status, treatment strategy and case fatality index of emerging COVID-19 infection at SMS Medical College Hospital, Jaipur, Rajasthan. It also evaluated efficacy of hydroxychloroquine (HCQ) in treatment of patients and risk of serious adverse outcomes in patients with COVID-19 in relation to their co morbid status. MATERIALS AND METHODS: In an attempt to provide extensive information pertaining to epidemiological and clinical characteristics of COVID-19, the present study was undertaken on 522 patients. The patients were COVID-19 confirmed positive by genomic analysis through Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) at SMS Medical College and Attached Hospitals, Jaipur. The indoor admitted patient's information inclusive of demographic profile (age, sex, nationality, residence), date of confirmation for positive COVID-19 case, travel/ exposure history, date of recovery/ death, clinical features, co morbidities and treatment plan was recorded. A serial follow-up of recovered patients to evaluate infective period of the disease was also part of the study. RESULTS: A total of 522 patients of laboratory confirmed COVID-19 test by RT-PCR at SMS Hospitals, Jaipur were assessed. Among the confirmed cases, most of patients were young adult in the age group with mean age of 35.42 years. 22.41% patients were below 20 years of age, majority of patients (58.80%) were in the age range of 21 to 50 years and only 18.79% patient population was in the age range of above 50 years. Females (39.08%) were affected less than males (60.91%) with an average sex ratio of female: male being 0.64. Out of the total analyzed patients, only 24.32% patients were symptomatic, among them fever (55.90%), cough (52.75%), sore throat (49.60%) and shortness of breath (46.45%) were the most common presenting clinical manifestations while a few patients also had symptoms of headache (26.77%), chest pain (6.29%) and other symptoms (7.87%) like pain abdomen, fatigue, joints pain, altered sensorium etc. Most of symptomatic patients belonging to older age group. An average of 40.40% patient population of above 50 years of age, were symptomatic while none of the patients below 10 years of age were symptomatic. 13.98% patients had some or the other underlying co morbid disease. The most prevalent co morbidity was hypertension (42.46%) followed by Diabetes mellitus (39.72%), Old k-chest (20.54%), COPD/ Bronchial Asthma (16.43%), Coronary artery disease (13.69%), Chronic kidney disease (13.69%) and Valvular heart disease (6.84%) distributed in co morbid patients of COVID-19. 60.27% of patient population with underlying co morbid conditions were more prone to develop symptomatology complex as compared to that observed in patients with no co morbidity (18.42%). 116 patients had recovered with effective treatment till the date of data analysis. Time of recovery was counted from the date of positive report to 1st negative report of oropharyngeal sample by RT-PCR for COVID-19 with an average recovery time of 8.15 days. 23.27% patients recovered within 5 days, while 52.58% patients took about 6-10 days, 23.27% patients took 11-15 days and remaining 0.86% took more than 16 days to recover. In the present study 15 patients had died till analysis of data, among the deceased, 73.33% were above 50 year of age with a male preponderance (66.6%). Interestingly, all deceased (100%) had presented with clinical manifestations of COVID-19 and all had underlying multiple co morbid conditions. Majority of patients had early mortality after admission to hospital with two third death account in initial three days. Asymptomatic patients (cases) treated with HCQ recovered early (average recovery time =5.4 days) compared to asymptomatic patients who did not receive any treatment (control group) and had longer recovery time (average recovery time =7.6 days). CONCLUSION: The varied spectra of COVID-19 mostly affects young adult age group (third to fifth decades of life). Interestingly, early age group was also affected in significant proportion when compared with similar data from other countries. It was observed that male population seemed to be was more prone to getting infected. Majority of COVID-19 positive patients (nearly three-fourth) were asymptomatic (mostly in young age range) at the time of diagnosis, which poses a major challenge for health care workers. Fever, cough, sore throat and shortness of breath were major symptoms that could be detected in such COVID-19 patients. Symptomatic clinical manifestations were more common in old age population. Infectivity was higher in patients that had underlying co morbid disease, especially in patients with multiple co morbid conditions. Symptomatic presentation of COVID-19 was observed to be higher in patients with co morbid disease. Average recovery time from COVID-19 was 8 days with effective treatment. Mortality in COVID-19 was higher in old age population, male gender, symptomatic and co morbid patients as compared to other similarly matched group. Most of mortality was noted within first few days of admission, suggestive of early mortality due to the primary disease process. Treatment with HCQ had early recovery without effectively influencing the overall mortality.

RESUMEN

Sexual practices among heterosexual men may differ between female sex workers (FSWs) and casual partners. We surveyed 203 heterosexual men and investigated the attributes associated with inconsistent condom use among them. Lower educational attainment was positively associated with inconsistent condom use with FSWs (adjusted prevalence ratio (aPR) 2.63; P = 0.018) and casual partners (aPR 1.55; P = 0.022), whereas early age of sexual debut (aPR 3.00; P = 0.012) and alcohol use during sex (aPR 7.95; P < 0.001) were positively associated with inconsistent condom use with FSWs. Socioecological factors may explain such differences.

RESUMEN

Background: Lifastuzumab vedotin (LIFA) is a humanized anti-NaPi2b monoclonal antibody conjugated to a potent antimitotic agent, monomethyl auristatin E, which inhibits cell division by blocking the polymerization of tubulin. This study is the first to compare an antibody-drug conjugate (ADC) to standard-of-care in ovarian cancer (OC) patients. Patients and methods: Platinum-resistant OC patients were randomized to receive LIFA [2.4 mg/kg, intravenously, every 3 weeks (Q3W)] or pegylated liposomal doxorubicin (PLD) (40 mg/m2, intravenously, Q4W). NaPi2b expression and serum CA-125 and HE4 levels were assessed. The primary end point was progression-free survival (PFS) in intent-to-treat (ITT) and NaPi2b-high patients. Results: Ninety-five patients were randomized (47 LIFA; 48 PLD). The stratified PFS hazard ratio was 0.78 [95% confidence interval (95% CI), 0.46-1.31; P = 0.34] with a median PFS of 5.3 versus 3.1 months (LIFA versus PLD arm, respectively) in the ITT population, and 0.71 (95% CI, 0.40-1.26; P = 0.24) with a median PFS of 5.3 months versus 3.4 months (LIFA versus PLD arm, respectively) in NaPi2b-high patients. The objective response rate was 34% (95% CI, 22% to 49%, LIFA) versus 15% (95% CI, 7% to 28%, PLD) in the ITT population (P = 0.03), and 36% (95% CI, 22% to 52%, LIFA) versus 14% (95% CI, 6% to 27%, PLD) in NaPi2b-high patients (P = 0.02). Toxicities included grade ≥3 adverse events (AEs) (46% LIFA; 51% PLD), serious AEs (30% both arms), and AEs leading to discontinuation of drug (9% LIFA; 8% PLD). Five (11%) LIFA versus 2 (4%) PLD patients had grade ≥2 neuropathy. Conclusion: LIFA Q3W was well tolerated and improved objective response rate with a modest, nonstatistically significant improvement of PFS compared with PLD in platinum-resistant OC. While the response rate for the monomethyl auristatin E-containing ADC was promising, response durations were relatively short, thereby highlighting the importance of evaluating both response rates and duration of response when evaluating ADCs in OC.

RESUMEN

Background: We have previously shown that raised p-S6K levels correlate with resistance to chemotherapy in ovarian cancer. We hypothesised that inhibiting p-S6K signalling with the dual m-TORC1/2 inhibitor in patients receiving weekly paclitaxel could improve outcomes in such patients. Patients and methods: In dose escalation, weekly paclitaxel (80 mg/m2) was given 6/7 weeks in combination with two intermittent schedules of vistusertib (dosing starting on the day of paclitaxel): schedule A, vistusertib dosed bd for 3 consecutive days per week (3/7 days) and schedule B, vistusertib dosed bd for 2 consecutive days per week (2/7 days). After establishing a recommended phase II dose (RP2D), expansion cohorts in high-grade serous ovarian cancer (HGSOC) and squamous non-small-cell lung cancer (sqNSCLC) were explored in 25 and 40 patients, respectively. Results: The dose-escalation arms comprised 22 patients with advanced solid tumours. The dose-limiting toxicities were fatigue and mucositis in schedule A and rash in schedule B. On the basis of toxicity and pharmacokinetic (PK) and pharmacodynamic (PD) evaluations, the RP2D was established as 80 mg/m2 paclitaxel with 50 mg vistusertib bd 3/7 days for 6/7 weeks. In the HGSOC expansion, RECIST and GCIG CA125 response rates were 13/25 (52%) and 16/25 (64%), respectively, with median progression-free survival (mPFS) of 5.8 months (95% CI: 3.28-18.54). The RP2D was not well tolerated in the SqNSCLC expansion, but toxicities were manageable after the daily vistusertib dose was reduced to 25 mg bd for the following 23 patients. The RECIST response rate in this group was 8/23 (35%), and the mPFS was 5.8 months (95% CI: 2.76-21.25). Discussion: In this phase I trial, we report a highly active and well-tolerated combination of vistusertib, administered as an intermittent schedule with weekly paclitaxel, in patients with HGSOC and SqNSCLC.
