Abstract
BACKGROUND Adverse childhood experiences (ACEs) increases vulnerability to externalising disorders such as substance misuse. The study aims to determine the prevalence of ACEs and its association with substance misuse. METHODS Data from the Consortium on Vulnerability to Externalising Disorders and Addictions (cVEDA) in India was used (n = 9010). ACEs were evaluated using the World Health Organisation (WHO) Adverse Childhood Experiences International Questionnaire whilst substance misuse was assessed using the WHO Alcohol, Smoking and Substance Involvement Screening Test. A random-effects, two-stage individual patient data meta-analysis explained the associations between ACEs and substance misuse with adjustments for confounders such as sex and family structure. RESULTS 1 in 2 participants reported child maltreatment ACEs and family level ACEs. Except for sexual abuse, males report more of every individual childhood adversity and are more likely to report misusing substances compared with females (87.3% vs. 12.7%). In adolescents, family level ACEs (adj OR 4.2, 95% CI 1.5-11.7) and collective level ACEs (adj OR 6.6, 95% CI 1.4-31.1) show associations with substance misuse whilst in young adults, child level ACEs such as maltreatment show similar strong associations (adj OR 2.0, 95% CI 1.1-3.5). CONCLUSION ACEs such as abuse and domestic violence are strongly associated with substance misuse, most commonly tobacco, in adolescent and young adult males in India. The results suggest enhancing current ACE resilience programmes and 'trauma-informed' approaches to tackling longer-term impact of ACEs in India.

Abstract
This Letter presents the first experimental evidence of the attractive strong interaction between a proton and a ϕ meson. The result is obtained from two-particle correlations of combined p-ϕ⊕ p[over ¯]-ϕ pairs measured in high-multiplicity pp collisions at sqrt[s]=13 TeV by the ALICE Collaboration. The spin-averaged scattering length and effective range of the p-ϕ interaction are extracted from the fully corrected correlation function employing the Lednický-Lyuboshits approach. In particular, the imaginary part of the scattering length vanishes within uncertainties, indicating that inelastic processes do not play a prominent role for the p-ϕ interaction. These data demonstrate that the interaction is dominated by elastic p-ϕ scattering. Furthermore, an analysis employing phenomenological Gaussian- and Yukawa-type potentials is conducted. Under the assumption of the latter, the N-ϕ coupling constant is found to be g_{N-ϕ}=0.14±0.03(stat)±0.02(syst). This work provides valuable experimental input to accomplish a self-consistent description of the N-ϕ interaction, which is particularly relevant for the more fundamental studies on partial restoration of chiral symmetry in nuclear medium.

Abstract
In the present study, healthy goats and sheep (n = 5) that were confirmed negative for peste des petits ruminants virus (PPRV) antibodies by monoclonal antibody-based competitive ELISA and by serum neutralization test and for PPRV antigen by s-ELISA were vaccinated with Sungri/96. A quantitative study was carried out to compare the proteome of peripheral blood mononuclear cells (PBMCs) of vaccinated goat and sheep [5 days post-vaccination (dpv) and 14 dpv] vs. unvaccinated (0 day) to divulge the alteration in protein expression following vaccination. A total of 232 and 915 proteins were differentially expressed at 5 and 14 dpv, respectively, in goats. Similarly, 167 and 207 proteins were differentially expressed at 5 and 14 dpv, respectively, in sheep. Network generated by Ingenuity Pathway Analysis was “infectious diseases, antimicrobial response, and inflammatory response,” which includes the highest number of focus molecules. The bio functions, cell-mediated immune response, and humoral immune response were highly enriched in goats at 5 dpv and at 14 dpv. At the molecular level, the immune response produced by the PPRV vaccine virus in goats is effectively coordinated and stronger than that in sheep, though the vaccine provides protection from virulent virus challenge in both. The altered expression of certain PBMC proteins especially ISG15 and IRF7 induces marked changes in cellular signaling pathways to coordinate host immune responses.

Abstract
Abstract
Aim
The COVID-19 pandemic has resulted in significant pressures on the NHS. Healthcare workers (HCWs) are at increased risk of infection. Personal protective equipment (PPE) lowers the risk of infection transmission. However, during the early phases of the pandemic, the information available regarding COVD-19 and the use of PPE has been unclear, with constantly changing guidelines. The aim of this study was to determine the knowledge and confidence about PPE usage among HCWs, in addition to measuring their anxiety levels during the COVID pandemic.
Method
A validated questionnaire was distributed among HCWs in as many UK hospitals as possible, during April 2020. The questionnaire consisted of 13 questions regarding demographics, knowledge on PPE guidance, HCW training and confidence levels in PPE usage and finally anxiety levels measured using the GAD-7 psychometric tool.
Results
1055 responses were received. Nurses (49%), Healthcare Assistants (HCA - 20%), Doctors (17%), Physios (8%) and other (6%). 99% of respondents indicated they were familiar with PPE guidance, but only 1.6% answered all 3 questions on PPE guidance accurately. 86.4% of respondents received mask-fitting checks. 79.7% received donning-doffing training. Despite this, only 46.8% were confident on their familiarity with PPE. 32.5% felt that their hospital communication regarding PPE policy during COVID-19 pandemic was poor or very poor. 30% HCWs experienced severe anxiety.
Conclusions
National guidance and local training on PPE usage during the COVID-19 pandemic has been unsatisfactory, leading to higher anxiety among HCWs. Improved information delivery and training are essential in preparation for the second wave and future pandemics.

Abstract
Diagnosis of osteoarticular tuberculosis (OATB) exhibits serious challenges owing to paucibacillary nature of specimens and localization of disease at sites that are difficult to access. We recently developed indirect immuno-PCR (I-PCR) and real-time I-PCR (RT-I-PCR) assays for the detection of mycobacterial antigen 85 complex (Ag85) in OATB patients. Detection limits for the purified Ag85 protein were found to be 1 and 41 fg ml-1 by I-PCR and RT-I-PCR, respectively, which were at least 105 -fold lower than respective ELISA. While spiking synovial fluids of non-TB control subjects with the purified Ag85 protein, LODs of 100 and 120 fg ml-1 were obtained by I-PCR and RT-I-PCR, respectively, thus demonstrating the sample matrix effect. Sensitivities of 87·5 and 70·5% were observed in bodily fluids of confirmed (n = 8) and clinically suspected (n = 51) OATB cases, respectively, by I-PCR, with a specificity of 93·9% (n = 33). Markedly, the sensitivities obtained by I-PCR/RT-I-PCR were significantly higher (P < 0·05-0·01) than ELISA and GeneXpert assay (n = 30). However, no substantial difference in sensitivity was observed between the I-PCR and RT-I-PCR assays. After further improving the accuracy of I-PCR, this test may lead to development of an attractive diagnostic kit.

Abstract
Two hundred [200] mothers consecutively attending Al-Fateh Paediatric Hospital, Benghazi in 1992 were interviewed. The majority of women were under 30 years of age, had primary or no education, were housewives, had no experience of pregnancy wastage or child loss, used no contraception, had one to three living children, had information about breast-feeding from the mother-in-law, a relative or a neighbour, considered breast-feeding a natural way, nutritionally superior and hygienic, and practised mixed feeding. The reasons for introducing artificial feeding were maternal in 49.7% of cases, filial [related to the baby] in 36.5% and due to social pressure in 13.8%. Measures for successful breast-feeding are emphasized

Phosphaturic mesenchymal tumors (PMTs) can present with vague symptoms of diffuse bone pain with pathologic fractures that often lead to a delayed diagnosis. We present a 60-year-old patient with a PMT that was persistently hypophosphatemic after resection, who was then successfully treated with cryoablation of the tumor. Tumor-induced osteomalacia (TIO) is a rare cause of hypophosphatemia characterized by vague symptoms of gradual muscle weakness and diffuse bone pain with pathologic fractures that often lead to a delayed diagnosis. This condition is usually caused by benign phosphaturic mesenchymal tumors (PMTs). Here, we present a case of persistent PMT after surgical resection treated with image-guided ablation. We present the patient's clinical examinations and laboratory findings (phosphorus, 1,25 (OH)2D, FGF-23, Intact PTH). Representative histologic images of a PMT are also presented. A 61-year-old male was evaluated for persistent hypophosphatemia and presumed osteomalacia. Six years earlier, he underwent surgical excision of a left ischial mass after presenting with TIO. The pathology was consistent with a PMT; however, hypophosphatemia persisted suggesting incomplete resection. He was treated with calcitriol and phosphate salts. A PET Ga68 dotatate scan of the patient revealed an avid left ischial mixed lytic and sclerotic lesions with marked amount of radiotracer uptake, suggesting persistent tumor. The patient was resistant to re-excision of the tumor due to the extended recovery period from his prior surgery and was treated instead with cryoablation of the tumor. His biochemical findings of hypophosphatemia and elevated FGF23 resolved after the ablation and have remained normal for 5 months after surgery. In patients with TIO, wide surgical excision is the treatment of choice. When this is not possible, image-guided ablation is an alternative therapeutic option.

Abstract
Ovine cysteine-rich secretory protein 1 (CRISP-1) is an acidic glycoprotein of epididymal origin under CRISP, antigen 5, pathogenesis-related protein 1 (CAP) super-family. The aim of the present study was the optimization of bacterial production and partial characterization of putative mature ovine CRISP-1 protein. The cDNA corresponding to T23 - C242 peptide fragment of ovine CRISP-1 protein was cloned into THE pET32b(+) expression vector using E. coli DH5α. Protein expression was carried out in E. coli BL21(DE3) by inducition with 1 mM IPTG at 37°C for 4 h. The recombinant protein was expressed as inclusion bodies and purified by Ni-NTA affinity chromatography using a pH gradient. Further purification of the protein was carried out by gel extraction following zinc sulfate negative staining. SDS-PAGE analysis of the purified recombinant CRISP-1 protein revealed a 43.8 kDa band. Bioactivity of the purified CRISP-1 protein was examined on sperm motility and capacitation. The recombinant ovine CRISP-1 protein at 5 µg/ml caused significant inhibition of sperm motility, and the activity was lost following heating the protein at 100°C for 5 min. The protein also demonstrated decapacitation activity, and at a concentration of 2 µg/ml, it caused a significant (P < 0.05) reduction in sperm capacitation. In conclusion, the thioredoxin-tagged ovine CRISP-1 protein was successfully produced in E. coli and purified in the soluble form by a combination of Ni-NTA affinity chromatography, gel purification, and dialysis. The recombinant protein exhibited both motility-inhibiting and decapacitating activities. Further study is needed to elucidate the mechanism of action and evaluate it's possible use in semen preservation.Abbreviations: CRISP-1: Cysteine-rich secretory protein-1; PCR: polymerase chain reaction; IPTG: isopropyl-β-D-thiogalactopyranoside; LB: Luria Bertani; SDS-PAGE: sodium dodecyl sulfate polyacrylamide gel electrophoresis; EDTA: ethylene diamine tetraacetic acid; Ni-NTA: Nickel nitrilotriacetic acid.

Abstract
The event-by-event correlations between three flow amplitudes are measured for the first time in Pb-Pb collisions, using higher-order symmetric cumulants. We find that different three-harmonic correlations develop during the collective evolution of the medium when compared to correlations that exist in the initial state. These new results cannot be interpreted in terms of previous lower-order flow measurements since contributions from two-harmonic correlations are explicitly removed in the new observables. A comparison to Monte Carlo simulations provides new and independent constraints for the initial conditions and system properties of nuclear matter created in heavy-ion collisions.

Abstract
Introduction
Our objective was to document the incidence of COVID-19 in vaccinated health care professionals and related personnel.
Method
We conducted an online survey to ascertain the incidence of COVID-19 symptoms, reverse transcriptase polymerase chain reaction (RT-PCR) positivity, effect on normal activity, need for anti-COVID-19 medication, hospitalization, and death among individuals who had completed both doses of COVID vaccination at least 2 weeks earlier.
Results
A total of 351 unique valid responses were received. Among the 340 people who had been vaccinated in India, 5% (17/340) had COVID-19 symptoms, 4.7% (16) became COVID-19 RT-PCR positive, 12 (3.5%) had sickness preventing normal daily activity, 2.65% (9) required anti-COVID-19 medication, and 1.18% (4) required hospitalization. Among family members living with the survey responders, the corresponding incidence was even lower. There was one death in this group.
Discussion
Being health care professionals, the responders would be at higher risk of daily exposure to COVID-19. Even in this high risk group, the vaccine efficacy is good. Vulture journalists should stop spreading fake news and misinformation that makes people hesitate taking the vaccine or be afflicted analysis paralysis. Every person who chooses to remain unvaccinated increases the risk for our entire community. We also need to follow universal precautions (wearing mask, physical distancing, handwashing) diligently without letting down our guard.

Abstract
Drug rash with eosinophilia and systemic symptoms (DRESS syndrome) is a severe, potentially life-threatening drug-induced hypersensitivity reaction characterized by cutaneous eruptions, fever, diffuse lymphadenopathy, along with eosinophilia and elevated liver enzymes. The severity and potential organ damage associated with DRESS mandates withdrawing the offending drug and provide a suitable replacement. We report a 55-year-old man who developed prolonged fever, generalized maculopapular rash and facial edema after 3 weeks of starting imatinib for chronic myeloid leukemia (CML). A diagnosis of DRESS was confirmed by eosinophilia and skin biopsy findings, along with a consistent RegiSCAR score. Imatinib was stopped and he was initiated on low-dose steroids, which led to complete resolution of rash and eosinophilia. A rechallenge with imatinib was positive, and he was switched to dasatinib for further therapy, following which he attained an optimal molecular response. DRESS following imatinib has only been reported in eight patients so far. In this report we summarize the current evidence for managing DRESS and its impact on the treatment of CML.

Abstract
Abstract
Study question
Is insulin resistance ( IR) a confounding variable in infertile women, other than those those having polycystic ovarian syndrome (PCOS)
Summary answer
IR was identified in 20.5% of infertile women. The presence of IR did not affect response to ovulation induction but reduced chances of conception
What is known already
Obesity is strongly correlated with insulin resistance. Obesity also has an adverse effect on fertility. In 2008 Steeg et al reported 5% reduction in chances of spontaneous conception with each unit increase in body mass index (BMI). Tetsurou Sakumoto et al (2010) reported hyperinsulinemia to affect granulose cells in small follicles inducing early response to luteinising hormone and anovulation. Adverse effect on endometrial function and implantation was also postulated. Insulin resistance has been studied in cases of PCOS but has not been studied in infertile women not fulfilling criteria for diagnosis of PCOS . So the present study was planned
Study design, size, duration
A prospective cohort study was conducted in infertility unit, King George Medical University, Lucknow, India over a period of one year from August 2018 to July 2019. Total 102 women with unexplained infertility were enrolled. Ethical clearance was obtained from institutional ethical committee
Participants/materials, setting, methods
Women with PCOS; diminished ovarian reserve documented by antral follicle count <7 and anti Mullerian hormone < 1.1ng/ml; bilateral tubal block; abnormal semen analysis; untreated hypothyroidism, hyperprolactinaemia; known diabetes were excluded. All women underwent ovulation induction with clomiphene citrate followed by single intrauterine insemination. Homeostasis model assessment insulin resistance index (HOMA IR) was calculated
HOMA-IR = Fasting S. Glucose (mg/dl) x Fasting insulin (µlU) / 405.
Value ≥ 2 denoted insulin resistance
Main results and the role of chance
: IR was identified in 21/102 (20.5%) cases. Fasting insulin levels were in the range of 5 – 9.9 mIU/ml in 53/102 women; <5mIU/ml in 29 and >10mIU/ml in 20. Fasting insulin > 9.45mIU/ml was found to have 90.5% sensitivity and 96.3% specificity in predicting insulin resistance. None of the cases had abnormal fasting and post prandial plasma glucose levels. IR was seen to be significantly correlated with BMI > 25kg/m2 (p = 0.0018) and waist hip ratio of > 0.85 (p = 0.0024).All women had follicular development and follicle rupture irrespective of presence of IR. Women with IR were more likely to have monofollicular development (17/21 IR cases). Correlation of endometrial thickness with IR was not seen. Mean endometrial thickness was 8.9mm. There were 6 pregnancies among the 102 women studied. None of the women with IR conceived.
So IR was found to be affecting one fifth of women with unexplained infertility. Failure of any woman with IR to conceive was significant but the finding needs to be further studied.
Limitations, reasons for caution
: It was a small study with only 102 cases and the women were followed for only one cycle of ovulation induction and intrauterine insemination so results need to be validated in a larger study with a longer follow up.
Wider implications of the findings: If further larger studies corroborate the role of IR in women with unexplained infertility it could elucidate the possibility of using insulin sensitisers in management of such cases. IR may emerge as an important gamechanger in management of unexplained infertility.

Abstract
Study question
Is the outcome of IVF/ICSI cycles done with continuous (single step ) embryo culture system different from that with sequential embryo culture system ?
Summary answer
Yes the outcome of IVF / ICSI cycles done with continuous (single step ) embryo-culture system is better than that with sequential embryo-culture system .
What is known already
Embryo culture media are important factors in IVF, which can significantly influence the clinical outcome of IVF/ICSI cycles. However it is not clear which formulation is most optimal and whether sequential or continuous media (single step) should be favored. Sequential media complies with embryo demands based on developmental stage , taking into account metabolic changes embryos undergo in-vivo, while moving from the oviduct to the uterus. The embryos in the early cleavage stage prefer to use pyruvate to produce energy, whereas once development nears the blastocyst stage , the embryos start using glucose in the process of glycolysis .
Study design, size, duration
A prospective RCT was carried out at our centre between 2018–2019 and IVF-ICSI patients meeting inclusion criteria (at least six normal MII - Oocytes) were included in this study. The aim of study was to compare blastocyst formation rates after embryo-culture in two different culture media systems. 436 metaphase II Oocytes from 62 women were randomly and equally divided to be fertilized and cultured to the blastocyst stage in either sequential media or single-step media.
Participants/materials, setting, methods
In this prospective trial with sibling oocytes, 436 metaphase II oocytes from 62 women were randomly and equally divided to be fertilized and cultured to the blastocyst stage in either sequential media ( n = 218 MII oocytes) or a single medium ( n = 218 MII oocytes). In both groups, embryos were cultured in an interrupted fashion with media changes on day 3. Embryo transfer was performed on day 5.
Main results and the role of chance
Blastocyst formation rates on day 5 were significantly higher following culture in single step media 60.55% (132 / 218 ) as compared to sequential media 34.86% ( 76 / 218) . The percentage of good quality blastocysts was also significantly higher in single step media. In conclusion, culture in single step media was associated with higher blastocyst formation rates compared to sequential media , suggesting that the single medium may provide better support to the developing embryo. The proportion of poor quality embryos was significantly higher in the sequential media group. Results indicate that embryo culture in continuous media could be as efficient as embryo culture in sequential media. A significant difference observed was the proportion of poor quality embryos on day 5 , which was significantly higher when the embryos were cultured in sequential media. Our results suggest that the type of embryo culture media can influence the quality of embryos both at the cleavage stage and blastocyst stage. The use of continuous embryo culture media does not seem to cause an adverse effect; in fact, their use can lower the workload in busy IVF labs and lower the stress that embryos are exposed to during handling.
Limitations, reasons for caution
Although single-step-medium for extended culture has practical advantages and blastocyst formation rates appear to be higher, there is insufficient evidence to recommend either sequential or single-step media as being superior for the embryo-culture to days 5/6. Further studies comparing these two media systems in well-designed trials should be performed.
Wider implications of the findings: When employing sequential media for embryo culture , it is necessary to transfer the embryos from one medium to another ( cleavage stage medium to blastocyst stage medium) which increases stress related embryo damage . Therefore, single-step media is beneficial as the embryos can develop undisturbed till blastocyst stage.

Singh M, Singh R. P–169 Does increasing the time interval between Oocyte-Retrieval and Oocyte-Denudation improve the results in ICSI cycles ? Hum Reprod 2021.

Abstract
Abstract
Study question
What should be the optimal time interval which elapses between oocyte retrieval and denudation followed by ICSI , for optimal results in ART cycles ?
Summary answer
Our study suggests that an optimum interval between oocyte retrieval and oocyte denudation followed by ICSI, leads to better results in ART cycles.
What is known already
It is widely accepted that the best timing for OPU is 34–39 hours after ovulation trigger. Some studies suggest that preincubation time before ICSI can be beneficial when it comes to fertilization and pregnancy rates while late ICSI (fertilization) may have negative results due to oocyte ageing. Other studies claim that there is no significant difference in ART results when ICSI is performed between 2–6 hours post Oocyte-Retrieval (OR) . Few studies state that 1–3 hours of COC-culture prior to denudation and oocyte injection is better as far as fertilization , embryo quality and improved oocyte cytoplasmic maturity is concerned.
Study design, size, duration
RCT of 234 ICSI cycles was carried out between 2017–2019. Patients were divided into two groups-: A- Early denudation with ICSI and B- Late denudation with ICSI.Both the groups were comparable in terms of female age, number of oocytes, day of transfer, number of embryos transferred and embryo quality. Fresh or frozen embryos were transferred , which were always derived from the same stimulation cycle. Exclusion criteria were : Severe male factor / TESA / PESA.
Participants/materials, setting, methods
234 ICSI cycles with similar ovarian stimulation protocols were analyzed as per time range between triggering, OPU, denudation and ICSI. Patients were divided into two groups: A- Early denudation (1–2 hours after OPU) with ICSI (1–2 hours after denudation) and B- Late denudation (4–6 hours after Oocyte-Retrieval ) with ICSI (1–2 hours after denudation).Primary outcomes were oocyte maturation and fertilization rates and secondary outcomes were clinical pregnancy rate and abortion rates.
Main results and the role of chance
In group B ( Late denudation and ICSI), the mean fertilization rate was 67% and the Clinical Pregnancy rate was 46%. This was better than the mean fertilization rate of 56% and clinical pregnancy rate of 39% observed in group A ( Early denudation and ICSI). However the difference was not statistically significant. Therefore, ideal maturation rates were observed when denudation ( followed by ICSI ) was delayed and done 4–6 hours after Oocyte-Retrieval. In ICSI cycles in ART , ovarian stimulation is used to induce the simultaneous growth of multiple follicles, followed by final maturation and ovulation triggering with exogenous hCG. or GnRH-Agonist or both. Generally, oocyte retrieval (OR) is performed 34 - 36h later. In addition, 2–4 hours in culture of the cumulus oocyte complexes (COC) prior to oocyte injection is believed beneficial for fertilization and embryo quality, probably due to improved oocyte cytoplasmic maturity. However, in large ART centers with high workloads, following such definite time intervals is frequently very difficult.
Limitations, reasons for caution
In large busy centers , maintaining meticulous time intervals is difficult . As our study numbers are small, larger multicentric trials are required in order to confirm our findings and to provide more robust data . This data cannot be applied to IVM, TESE / PESE and severe male-factor infertility.
Wider implications of the findings: To achieve a successful fertilization, both nuclear and cytoplasmic maturity are required. Our Study indicates that a slight delay in denudation following Oocyte-Retrieval , will yield a higher number of good quality oocytes. A higher success rate can also be expected due to more number of embryos available for transfer.

Abstract
Abstract
Study question
This study evaluated differences in semen parameters in male cancer patients in our ethnic population who banked their sperms prior to cancer treatment
Summary answer
We found significant differences in semen concentration, motility and morphology between different types of cancers, especially testicular cancers
What is known already
Impaired spermatogenesis and abnormal semen parameters in cancer patients has been noted, however certain cancer types are more damaging than others. In testicular cancer, spermatogenesis impairment is more quantitative than qualitative with sperm morphology being the most affected parameter. Among non testicular cancers, lymphoma cases usually show the most significantly impaired semen parameters
Study design, size, duration
We conducted a retrospective study analyzing semen parameters in 49 cancer patients between October 2014 to January 2020 who presented to the onco-fertility unit, Max Multispeciality Hospitals, New Delhi.
Furthermore, we did our analysis based on total of 101 samples and were broadly divided into testicular (37 samples) and non testicular cancers (64 samples). Patients who had previously received any form of cancer treatment including chemotherapy or radiotherapy were not included in this study
Participants/materials, setting, methods
Testicular Cancer(TC) group was further subcategorized into Seminoma and Non Seminoma groups whereas Non Testicular Cancer (NTC) group was subcategorized into Lymphoma and Non Lymphoma groups. Semen was collected by masturbation and analysis was performed in keeping with the WHO criteria. Statistical analyses was performed using SPSS software. p values <0.05 were considered to indicate statistical significance.
Main results and the role of chance
In Testicular cancer (TC), 92% samples (34/37) had abnormal semen parameters whereas only 24.4% samples (22/64) were abnormal in Non Testicular cancer (NTC). Additionally, there were significant differences in sperm concentration, motility and morphology between TC and NTC groups.
Individually,
TC: Oligozoospermia was seen in 73% (27/37) with subdivision between Seminoma and Non Seminoma groups being 81.3% (13/16) and 61.9% (13/21).
Asthenozoospermia was seen in 86.5% (32/37) samples with subdivision between Seminoma and Non Seminoma groups being 87.5% (14/16) and 81% (17/21).
Teratozoospermia was seen in 59.5% (22/37) samples with subdivision between Seminoma and Non Seminoma groups being 75% (12/16) and 42.86% (9/21).
Combined OATS observed in 59.5% (22/37) samples with subdivision between Seminoma and Non Seminoma groups being 75% (12/16) and 42.86% (9/21)
NTC: Oligozoospermia was seen in 18.8% (12/64) samples with subdivision between Lymphoma and Non Lymphoma groups being 26.92% (7/26) and 26.32% (10/38).
Asthenozoospermia was seen in 32.8% (21/64) samples with subdivision between Lymphoma and Non Lymphoma groups being 34.62% (9/26) and 34.21% (13/38).
Teratozoospermia was seen in 17.2% (11/64) samples with subdivision between Lymphoma and Non Lymphoma groups being 26.9% (7/26) and 23.68% (9/38).
Combined OATS observed in 17.2% (11/64) samples with subdivision between Lymphoma and Non Lymphoma groups being 26.9% (7/26) and 23.68% (9/38).
Limitations, reasons for caution
Study was conducted in a single institution with lesser overall number of patients. Duration, staging and grading of cancers were also not individually assessed, which could be a further limiting factor.
Wider implications of the findings: Testicular cancers, especially seminomas, have the most severe effect upon semen parameters. Among NTC patients, lymphomas have the worst impact. Knowing the varying effect of different cancers on semen parameters in our ethnic population helps ART specialists and oncologists to appropriately modify patient counseling and improve fertility outcomes.

Soft-Dielectron Excess in Proton-Proton Collisions at sqrt[s]=13 TeV. PHYSICAL REVIEW LETTERS 2021; 127:042302. [PMID: 34355943 DOI: 10.1103/physrevlett.127.042302] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 04/12/2021] [Accepted: 06/08/2021] [Indexed: 06/13/2023]
Abstract
A measurement of dielectron production in proton-proton (pp) collisions at sqrt[s]=13 TeV, recorded with the ALICE detector at the CERN LHC, is presented in this Letter. The data set was recorded with a reduced magnetic solenoid field. This enables the investigation of a kinematic domain at low dielectron (ee) invariant mass m_{ee} and pair transverse momentum p_{T,ee} that was previously inaccessible at the LHC. The cross section for dielectron production is studied as a function of m_{ee}, p_{T,ee}, and event multiplicity dN_{ch}/dη. The expected dielectron rate from hadron decays, called hadronic cocktail, utilizes a parametrization of the measured η/π^{0} ratio in pp and proton-nucleus collisions, assuming that this ratio shows no strong dependence on collision energy at low transverse momentum. Comparison of the measured dielectron yield to the hadronic cocktail at 0.15<m_{ee}<0.6 GeV/c^{2} and for p_{T,ee}<0.4 GeV/c indicates an enhancement of soft dielectrons, reminiscent of the "anomalous" soft-photon and soft-dilepton excess in hadron-hadron collisions reported by several experiments under different experimental conditions. The enhancement factor over the hadronic cocktail amounts to 1.61±0.13(stat)±0.17(syst,data)±0.34(syst,cocktail) in the ALICE acceptance. Acceptance-corrected excess spectra in m_{ee} and p_{T,ee} are extracted and compared with calculations of dielectron production from hadronic bremsstrahlung and thermal radiation within a hadronic many-body approach.

Abstract
BACKGROUND Sutured inguinal hernia repairs are now uncommon, with evidence suggesting that those augmented with mesh are associated with a lower recurrence rate. We aimed to explore the suggestion that the established use of mesh does indeed lower the rate of operation for recurrence in a single National Health Service region. METHOD We collected retrospective Office of Population Censuses and Surveys coded data across one region of all primary and recurrent inguinal hernia repairs over 15 years (2004-2019). Electronic records of recurrent repairs were scrutinised to identify year and type of previous primary repair. RESULTS In total, 7,234 repairs were performed during this time, of which 289 (4%) were for symptomatic recurrence. Operations for primary repair increased year on year (111 in 2004 to 402 in 2019). Frequency of operation for recurrent herniation declined with increasing use of mesh (8.8% in 2004 to 3.5% in 2019). The majority of repairs (73%) for recurrence were by an open approach. As opposed to an open mesh repair, a primary laparoscopic repair was associated with an earlier recurrence. CONCLUSIONS Inguinal hernia repairs are increasing in frequency but operations for later symptomatic recurrence following an open primary prosthetic mesh repair are not.

Abstract
Copy number variations (CNVs) are major forms of genetic variation with an increasing importance in animal genomics. This study used the Illumina BovineSNP 50 K BeadChip to detect the genome-wide CNVs in the Tharparkar cattle. With the aid of PennCNV software, we noticed a total of 447 copy number variation regions (CNVRs) across the autosomal genome, occupying nearly 2.17% of the bovine genome. The average size of detected CNVRs was found to be 122.2 kb, the smallest CNVR being 50.02 kb in size, to the largest being 1,232.87 Kb. Enrichment analyses of the genes in these CNVRs gave significant associations with molecular adaptation-related Gene Ontology (GO) terms. Most CNVR genes were significantly enriched for specific biological functions; signaling pathways, sensory responses to stimuli, and various cellular processes. In addition, QTL analysis of CNVRs described them to be linked with economically essential traits in cattle. The findings here provide crucial information for constructing a more comprehensive CNVR map for the indigenous cattle genome.

Abstract
Abstract
Introduction
Junior doctors are increasingly encountering Advance Care Planning (ACP) when they look after frail, older or multi-morbid patients during their hospital rotations. However, there remains a lack of formal training and resources, particularly with DNACPR discussions and when engaging patients and their loved ones with Emergency Health Care Planning (EHCP). We aimed to assess the need for ACP, improve the infrastructure by which ACP is delivered, and better support junior doctors to have these difficult conversations.
Method
Discharges from the Geriatrics Department at Kettering General Hospital were reviewed initially in May 2019 and again in January 2020 following intervention. We introduced a focused communication skills training session delivered at departmental teaching, which included a combination of simulation training and lectures. We additionally designed and implemented an EHCP template to aid junior doctors’ discussions. This could also be copied to the discharge letter, to facilitate safe transfer of care to primary care.
Results
In May 2019 of 32 patients, 100% met at least one SPICTTM criterion, with median of 4 criteria, thus indicating a high need for ACP in this cohort. Despite this, only one discharge letter included an EHCP and two had a request for GP colleagues to complete one. Evaluation of discharges again in January of 2020 reconfirmed a similar need for ACP, but following our interventions, the number of EHCP’s performed had increased. Of 22 identified patients 4 had a completed EHCP and 3 were requested for completion by their GP. Qualitative questionnaires demonstrated an improvement in both knowledge and confidence amongst junior doctors following the training session.
Conclusion
We have shown that there is a necessity for ACP to be considered for Geriatrics inpatients, and that providing structure and training in this challenging area offers benefit to both patients and junior doctors.

Abstract
Wider implementation of AI in sheep in the field condition has not been possible till date due to very poor conception rate after cervical insemination with cryopreserved semen. Poor cervical penetrability in ewe and diminished sperm functions in cryopreserved semen are considered responsible for it. In the present study, effect of carboxymethyl cellulose (CMC) on post-thaw qualities of ram semen was investigated. Ejaculates from eight adult Malpura rams were pooled and diluted (800 × 106 sperm mL-1) with TES-Tris-fructose-egg yolk extender having either 5 or 6% glycerol and supplemented with 0, 0.25, 0.5, 0.75 and 1.0% (w/v) CMC and packaged into 0.25 mL French mini straws. The straws were progressively cooled to 5 °C inside a cold cabinet (5 °C) and then equilibrated for 22 h inside a refrigerator (2-5 °C). Straws were frozen at -25 °C min-1 up to -125 °C using a programmable cell freezer (Planer Biomed R-204, UK) and finally plunged into liquid nitrogen. The post-thaw progressive motility was higher (P < 0.05) in 0.75% CMC-treated group compared to control. Overall, both pre-freeze and post-thaw sperm kinetics was comparable between CMC-treated and control groups. The post-thaw sperm viability, acrosomal integrity and sperm with high mitochondrial membrane potential (hMMP) were relatively higher while sperm with high membrane cholesterol was significantly (P < 0.05) higher in presence of 0.25% CMC compared to the control. Both sperm having hMMP and non-capacitated sperm were significantly (P < 0.05) higher in presence of 5% glycerol than 6% glycerol. Similarly, functional membrane integrity (FMI) was higher in presence of 5% glycerol than 6% glycerol when CMC was added at 0.5% to extender. In conclusion, both 0.25% CMC and 5% glycerol resulted in improvement in several post-thaw sperm functions in cryopreserved ram semen. Thus CMC demonstrated cryoprotective effect on ram sperm in a synergistic manner with glycerol.

JOURNAL OF ENVIRONMENTAL MANAGEMENT 2021; 285:112116.

Abstract
Air pollution due to dust emission is continuously increasing day by day in mining and allied industrial areas. Mining operations contribute a substantial amount of dust emission at the crushing, screening, and bulk material handling in loading areas. The ambient suspended dust particles create a severe nuisance to workers and local dwellers. For effective controlling of positive dust emission, an innovative automated dry fog dust suppression system (DFDSS) has been developed using hybrid nozzles, sensors, actuators, controllers, screw compressors, air receivers, pumps, motors, and water arrangement with filtration facility. The DFDSS was installed in a crushing and screening plant of an iron ore mine in India. Performance study indicted fugitive dust emission concentration values ranged from 354 to 7040 μg m-3, which was reduced to 91-300 μg m-3 after installation of DFDSS. The reduced values were within the permissible limit of 1200 μg m-3 at a distance of 25 ± 2 m in the predominant downwind direction. The installed DFDSS added a meager addition of moisture content of 0.032% in the handling iron ore material, which was below the acceptable limit of 0.1%. The DFDSS precisely regulated fugitive dust emission from various mining activities without affecting the minerals processing performance. Thus, the DFDSS can be implemented effectively in different mining and allied industries where there is a dust emission problem.

Abstract
The elliptic flow of electrons from beauty hadron decays at midrapidity (|y|<0.8) is measured in Pb-Pb collisions at sqrt[s_{NN}]=5.02 TeV with the ALICE detector at the LHC. The azimuthal distribution of the particles produced in the collisions can be parametrized with a Fourier expansion, in which the second harmonic coefficient represents the elliptic flow, v_{2}. The v_{2} coefficient of electrons from beauty hadron decays is measured for the first time in the transverse momentum (p_{T}) range 1.3-6 GeV/c in the centrality class 30%-50%. The measurement of electrons from beauty-hadron decays exploits their larger mean proper decay length cτ≈500 μm compared to that of charm hadrons and most of the other background sources. The v_{2} of electrons from beauty hadron decays at midrapidity is found to be positive with a significance of 3.75 σ. The results provide insights into the degree of thermalization of beauty quarks in the medium. A model assuming full thermalization of beauty quarks is strongly disfavored by the measurement at high p_{T}, but is in agreement with the results at low p_{T}. Transport models including substantial interactions of beauty quarks with an expanding strongly interacting medium describe the measurement within uncertainties.
