Abstract
BACKGROUND Cirsoid aneurysm of the scalp is a rare arteriovenous fistula having a traumatic, congenital, iatrogenic, or idiopathic etiology. Its presentation can range from a small swelling to a large pulsatile mass with tinnitus, headache, and scalp necrosis. OBSERVATIONS A 67-year-old female presented with a gradually increasing swelling on her forehead and head since childhood and no history of trauma. Examination revealed 12 × 5 cm tortuous midline swelling. Computed tomography angiography revealed a mass of tortuous vessels in the right frontoparietal region of the scalp with no bony defect or intracranial extension. Contrast-enhanced computed tomography of the head showed no intracranial pathology. The diagnosis of cirsoid aneurysm was made, and surgery was planned. A bicoronal incision was made. The feeding arteries were dissected and ligated. The nidus was carefully separated, cauterized, and excised in toto. Inadvertently, a buttonhole in the skin was created while dissecting the nidus, which was sutured. The patient developed a small area of scalp necrosis on the 10th postoperative day, which was debrided and sutured. At the 6-month follow-up, no signs of recurrence were present. LESSONS A large cirsoid aneurysm of the scalp with multiple arterial supplies can be treated successfully with surgery. Meticulous dissection and hemostasis are warranted to avoid perioperative complications.

Abstract
BACKGROUND The United Kingdom (UK) has committed to the World Health Organization's viral hepatitis elimination targets. New case finding strategies, such as antenatal testing, may be needed to achieve these targets. We conducted a rapid review to understand hepatitis C-specific antibody (anti-HCV) and HCV RNA test positivity in antenatal settings in the United Kingdom to inform guidance. METHODS Articles and conference abstracts published between January 2000 and June 2022 reporting anti-HCV testing in antenatal settings were identified through PubMed and Web of Science searches. Results were synthesised using a narrative approach. RESULTS The search identified 2,011 publications; 10 studies were included in the final synthesis. Seven studies used anonymous testing methods and three studies used universal opt-out testing. Anti-HCV test positivity ranged from 0.1 to 0.99%, with a median value of 0.38%. Five studies reported HCV RNA positivity, which ranged from 0.1 to 0.57% of the testing population, with a median value of 0.22%. One study reported cost effectiveness of HCV and found it to be cost effective at £9,139 per quality adjusted life years. CONCLUSION The relative contribution of universal opt-out antenatal testing for HCV should be reconsidered, as antenatal testing could play an important role in new case-finding and aid achieving elimination targets.

Abstract
INTRODUCTION The multiorgan impact of moderate to severe coronavirus infections in the post-acute phase is still poorly understood. We aimed to evaluate the excess burden of multiorgan abnormalities after hospitalisation with COVID-19, evaluate their determinants, and explore associations with patient-related outcome measures. METHODS In a prospective, UK-wide, multicentre MRI follow-up study (C-MORE), adults (aged ≥18 years) discharged from hospital following COVID-19 who were included in Tier 2 of the Post-hospitalisation COVID-19 study (PHOSP-COVID) and contemporary controls with no evidence of previous COVID-19 (SARS-CoV-2 nucleocapsid antibody negative) underwent multiorgan MRI (lungs, heart, brain, liver, and kidneys) with quantitative and qualitative assessment of images and clinical adjudication when relevant. Individuals with end-stage renal failure or contraindications to MRI were excluded. Participants also underwent detailed recording of symptoms, and physiological and biochemical tests. The primary outcome was the excess burden of multiorgan abnormalities (two or more organs) relative to controls, with further adjustments for potential confounders. The C-MORE study is ongoing and is registered with ClinicalTrials.gov, NCT04510025. FINDINGS Of 2710 participants in Tier 2 of PHOSP-COVID, 531 were recruited across 13 UK-wide C-MORE sites. After exclusions, 259 C-MORE patients (mean age 57 years [SD 12]; 158 [61%] male and 101 [39%] female) who were discharged from hospital with PCR-confirmed or clinically diagnosed COVID-19 between March 1, 2020, and Nov 1, 2021, and 52 non-COVID-19 controls from the community (mean age 49 years [SD 14]; 30 [58%] male and 22 [42%] female) were included in the analysis. Patients were assessed at a median of 5·0 months (IQR 4·2-6·3) after hospital discharge. Compared with non-COVID-19 controls, patients were older, living with more obesity, and had more comorbidities. Multiorgan abnormalities on MRI were more frequent in patients than in controls (157 [61%] of 259 vs 14 [27%] of 52; p<0·0001) and independently associated with COVID-19 status (odds ratio [OR] 2·9 [95% CI 1·5-5·8]; padjusted=0·0023) after adjusting for relevant confounders. Compared with controls, patients were more likely to have MRI evidence of lung abnormalities (p=0·0001; parenchymal abnormalities), brain abnormalities (p<0·0001; more white matter hyperintensities and regional brain volume reduction), and kidney abnormalities (p=0·014; lower medullary T1 and loss of corticomedullary differentiation), whereas cardiac and liver MRI abnormalities were similar between patients and controls. Patients with multiorgan abnormalities were older (difference in mean age 7 years [95% CI 4-10]; mean age of 59·8 years [SD 11·7] with multiorgan abnormalities vs mean age of 52·8 years [11·9] without multiorgan abnormalities; p<0·0001), more likely to have three or more comorbidities (OR 2·47 [1·32-4·82]; padjusted=0·0059), and more likely to have a more severe acute infection (acute CRP >5mg/L, OR 3·55 [1·23-11·88]; padjusted=0·025) than those without multiorgan abnormalities. Presence of lung MRI abnormalities was associated with a two-fold higher risk of chest tightness, and multiorgan MRI abnormalities were associated with severe and very severe persistent physical and mental health impairment (PHOSP-COVID symptom clusters) after hospitalisation. INTERPRETATION After hospitalisation for COVID-19, people are at risk of multiorgan abnormalities in the medium term. Our findings emphasise the need for proactive multidisciplinary care pathways, with the potential for imaging to guide surveillance frequency and therapeutic stratification.

Abstract
PURPOSE/OBJECTIVE(S) Both interstitial multi-catheter brachytherapy based accelerated partial breast irradiation (APBI) and ultra-hypo-fractionated whole breast irradiation (WBI) with 5 fractions can complete treatment in a short time and result in lower treatment-related costs. Although data are available on their toxicity compared with conventional and hypo-fractionated regimens, there are few data directly comparing these two techniques. MATERIALS/METHODS This prospective cohort study enrolled early breast cancer patients with negative ink margin, T1 or T2 stage, and tumor size of 3 cm or less, with 0 to 3 positive lymph nodes after adequate axillary dissection or negative sentinel lymph node biopsy (N0-1), regardless of receptor status (ER, PR, HER2neu). Of the total 31 patients, 15 received APBI with multi-catheter interstitial brachytherapy (35 Gy in10 fractions over 5 days with a minimum interval of 6 hours between fractions) and 16 patients received WBI (27 Gy in 5 fractions over 5 days) with either 3DCRT or VMAT technique. Acute toxicity was assessed using the RTOG toxicity grading and breast cosmesis was assessed using the Harvard breast cosmesis score. Toxicity and cosmesis were assessed immediately after treatment, after one month, and after three months of treatment. Results were compared between groups using the Mann Whitney U test. RESULTS All patients completed a 3-month follow-up after completion of treatment. There was no statistically significant difference between the 2 groups in terms of highest grade toxicity (p = 0.97) and acute toxicity immediately after RT (p = 1.0) and after 1 month of RT (p = 0.91). However, at 3 months, more patients in the WBI group had a residual skin reaction than in the APBI group (p = 0.03). There was no statistically significant difference in breast cosmesis scores at any time point. 53.3%, 6.6% had grade 1 and 2 skin toxicities respectively immediately after RT in the APBI group and 62.5% of patients had grade 1 skin toxicity in WBI group. After 1 month 26.6%, 26.6% & 13.3% patients had grade 2, grade 1 and grade 3 toxicities respectively. In the WBI group, at 1 month, 50%, 18.7% and 12.5% patients had grade 1, 3 and 2 skin toxicities respectively. At 3 months, 42.8% and 7.1% of patients in the APBI group had grade 1 and grade 2 toxicities, respectively. In the WBI group, 78.5% and 7.1% of patients had grade 1 and 2 skin toxicities respectively. CONCLUSION In this study, no difference in acute toxicity or breast cosmesis was demonstrated between APBI-based interstitial brachytherapy and ultra-hypo-fractionated WBI. Since both regimens can be administered within 5 days, the decision between them is challenging for both physicians and patients. This study can be considered hypothesis-generating and used for further planning of equivalence or noninferiority studies.

Abstract
PURPOSE/OBJECTIVE(S) In locally advanced squamous cell carcinoma of the head and neck (LAHNSCC), the main goal of treatment remains survival while improving quality of life (QOL). In recent decades, there has been a paradigm shift in the measurement of clinical outcomes in patients diagnosed with cancer, focusing on the patient perspective by incorporating patient-reported outcomes (PROs). The primary objective of this study was to evaluate the improvement in quality of life with the use of cyclic hypo-fractionated palliative QUAD SHOT radiotherapy (RT) with concurrent cisplatin (CDDP) in previously untreated patients with incurable LAHNSCC. MATERIALS/METHODS In this prospective interventional phase- II study, 60 patients with locally advanced squamous cell carcinoma of the head and neck, majority stage IVB, ECOG PS ≤ 3, were treated with QUAD SHOT RT (14 Gy/4 fractions/2 days - BD with 6-hour interval and concurrent CDDP at 6 mg/m2. This treatment was repeated at 4-week intervals for 2 additional cycles if tumor progression did not occur. Serial changes in HR -QoL were assessed using EORTC QLQ C-30 and H&N-35) at 4 different time points. Statistical methods such as the Wilcoxon signed-rank test and Friedman test were used to compare QoL values at different time points with Bonferroni correction for multiple comparisons to control for type I errors. RESULTS The median global health score (GHS) at baseline was 41.667, with an initial increase in score at 4 weeks (50.00) and at 8 weeks (54.167) that did not continue at 12 weeks (41.667). Symptoms related to toxicities (speech, social contact, sticky saliva, dry mouth, senses in H&N 35) were lower after 4 weeks. Application of the Friedman test for four time points revealed significant improvement in role function at 4 weeks, which remained constant at 8 weeks but was not sustained at 12 weeks. Comparison of HN-35 symptom scores between the four time points showed improvement in symptoms such as pain, swallowing, and mouth opening at 4 and 8 weeks. The mean QLQ C30 summary score for these patients improved at four weeks but did not remain constant at 8 and 12 weeks. CONCLUSION Our study showed significant improvement in quality-of-life parameters and reduction in symptom burden at 4 and 8 weeks due to disease control and symptom palliation by QUADSHOT CTRT, while quality-of-life scores worsened and symptom scores were not maintained at 12 weeks due to disease progression and occurrence of acute toxicities. This phase II study may serve as the basis for designing a phase III randomized control trial to compare quality of life changes with QUADSHOT CTRT and other palliative CTRT regimens.

Abstract
PURPOSE/OBJECTIVE(S) The objectives of this study are: 1) To compare the acute toxicity caused in the treatment of locally advanced cervical cancer (LACC) treated with weekly multiple applications vs. a single application for image-guided intracavitary High Dose Rate (HDR) brachytherapy (BT) after External Beam Radiation Therapy (EBRT) 2) To compare the loco-regional control of cancer at six months in the two arms MATERIALS/METHODS: In a prospective study, 40 patients with biopsy-proven LACC with FIGO-2018 stage IIB-IIIC1 disease, underwent EBRT to the pelvis at a dose of 50.4 Gy/ 28 fractions over 5.5 weeks with weekly concurrent cisplatin. After completion of EBRT, they were randomized into two arms with 20 patients each. In the Control arm (Arm-A), BT sessions were given with weekly 3 applications whereas, in the experimental arm (Arm-B), all the sessions were given with a single application at 6-12 hours intervals with aim of the high-risk clinical target volume receiving >80 Gy EQD2 and 2 cm3 of the bladder and rectum/sigmoid receiving <85 Gy and <75 Gy, respectively. The OAR contouring was done on CT RESULTS: All 40 patients were treated as per protocol. The mean duration of treatment including EBRT and BT was 73.15 days [95% CI 68.63-77.66] in Arm A and 55.85 days [95% CI 52.11-59.58] in Arm B which was significant. After 6 months, 37 patients came for follow-up, all 19 patients in Arm A had Grade 1 or Grade 2 rectal toxicity. In Arm B as well all 18 patients had Grade 1 or Grade 2 rectal toxicity. Bladder toxicity was Grade 1 or Grade 2 in 18 patients and Grade 3 severity in 1 patient among Arm A. Among 18 patients of Arm B, bladder toxicity of Grade 1 or Grade 2 was seen in 16 patients, and 2 patients had grade 3 toxicity. 2 patients in Arm A and 3 in Arm B complained of Grade 1 urinary incontinence. Moreover, Abdominal pain at 6 months was of Grade 1 in around 6 patients in Arm A but 14 patients had abdominal pain in Arm B which was of Grade 1 in 8, 4 had grade 2 and 2 patients had grade 3 severity abdominal pain. In the monthly analysis of acute toxicity, none of the patients showed Grade 3 or 4 toxicity at the 1st, 2nd, or 3rd month of completion of treatment. When comparing local control in both arms at 6 months, 2 patients had treatment failure in the Experimental Arm compared to only 1 patient in the Control Arm CONCLUSION: Single Application Multiple Fraction Intracavitary Brachytherapy post concurrent CTRT is a safe option for the treatment of locally advanced cervical cancer. When compared to the weekly application arm, single-application ICRT showed a comparable acute toxicity profile and comparable local control rates as well. Some patients in Single Application Arm showed abdominal pain which needs to be investigated with further trials. The overall treatment time in the single application arm is significantly lower than the standard weekly application arm.

Abstract
PURPOSE/OBJECTIVE(S) Biological Response in Hepatocellular carcinoma (HCC) is measured in terms of serum alpha-fetoprotein (AFP) which is elevated in nearly 60% HCC patients at baseline and is directly related to the severity of the disease. This biological response is defined as the reduction of more than 50% from the baseline levels and is associated with an increased percentage of tumor necrosis and is directly related to increased loco-regional control. Patients diagnosed with HCC have very limited treatment modalities. With the recent advances in the field of radiation therapy and the development of Stereotactic Body radiotherapy (SBRT), the role of radiotherapy has increased as a loco-regional modality for HCC. In this single-arm prospective study, we evaluated the biological response post-SBRT in patients diagnosed with HCC. MATERIALS/METHODS We conducted a prospective study that included patients diagnosed with HCC with baseline elevation of serum AFP, Child-Turcotte Pugh (CTP) Class A/B with a maximum score of 7. Patient's serum AFP levels were recorded at baseline, pre-treatment, and post-treatment. The biological response was measured at 3 months post-treatment and compared with the baseline serum AFP levels using Wilcoxon signed rank test. RESULTS A total of 14 patients with HCC were recruited and received SBRT to the target lesion, with a dose between 30-42 Gy over 6 fractions treated on alternate days. Patients were assessed post-treatment at one month with triphasic CEMRI and serum AFP levels. 12 out of 14 patients (85.71%) had a biological response at 3 months follow-up and levels showed further decline unless a progression was found. The median (IQR) serum AFP level was 1131 ng/ml (359-5668 ng/ml) at baseline. Post-treatment serum AFP levels had a median (IQR) value of 156 ng/ml (15-372 ng/ml) showing a near reduction of 86% from baseline, which was significant. 2/14 pts (14.28%) showed no reduction or even increase in serum AFP levels post-treatment. CONCLUSION This prospective single-arm study demonstrated the vital role of SBRT in the treatment of HCC and its importance in achieving a better disease control. The response was achieved in 86% of patients with marked reduction of nearly 90% in serum AFP levels as compared to the baseline and increased median OS and PFS as compared to patients not receiving radiotherapy. Further prospective studies are warranted to confirm our findings.

Abstract
PURPOSE/OBJECTIVE(S) Shorter palliative hypo-fractionated radiotherapy regimens given concurrently with chemotherapy, preferably cisplatin (radiosensitizer), increase response rates with acceptable toxicity, leading to better compliance of patients with locally advanced squamous cell carcinoma of the head and neck (LAHNSCC) in whom late toxicities due to chemoradiotherapy are less relevant. This single institution prospective interventional phase II study was conducted with the goal of achieving high rates of locoregional control with acceptable treatment-related toxicity. MATERIALS/METHODS In this prospective interventional phase- II study, 60 patients with LAHNSCC (treatment naive), the majority in stage IVB and ECOG PS ≤ 3, were treated with QUAD SHOT RT using the conventional 2D technique (14Gy in 4 fractions on 2 consecutive days twice daily with a 6-hour interval between the two fractions) and concurrent cisplatin (CDDP) at a dose of 6 mg/m2. This treatment was repeated at 4-week intervals for 2 additional cycles if tumor progression did not occur. The Kaplan-Meier method was used to determine survival probability for progression-free survival (PFS) and overall survival (OS). Descriptive statistics with number and percentage were used for each toxicity and tumor response at different time points. A P value of less than 0.05 was considered significant. RESULTS In our study, all patients received at least one cycle of QUADSHOT chemoradiotherapy (CTRT), while 35 and 18 patients received the 2nd and 3rd QUADSHOT CTRT, respectively. Of the patients who completed the first cycle of QUADSHOT CTRT, 27 (45%) patients had a partial response (PR) and 22 (36.7%) had stable disease (SD). Of the patients who completed the second cycle QUADSHOT CTRT, 77.2% had SD, while 11.4% had PR and 11.4% had PD. After the 3rd QUADSHOT CTRT, 72.2% had SD, while 11.1% had PR and 16.7% had PD. The overall response rate (SD +PR) in our study was 81%, 88.6%, and 83% after the 1st, 2nd, and 3rd QUADSHOT CTRT, respectively. After the 3rd QUADSHOT CTRT, no patient showed grade 4 toxicity. Most patients had grade I/ II toxicities e.g., skin (grade I -83%), mucositis (grade II -50%), salivary gland toxicity (grade II -50%), grade I laryngitis (83.3%). Grade- III oral mucositis and pharyngitis were seen in 27% and 6.7% of patients, respectively. Median OS and PFS were 7.9 months and 6.2 months, respectively. CONCLUSION Concurrent chemotherapy acts as a radiosensitizer and provides a synergistic effect when coupled with hypo-fractionated radiation, resulting in more effective control of locoregional disease in locally advanced head and neck tumors with acceptable toxicities. This study is hypothesis-generating and may serve as a basis for developing optimal CTRT regimens for patients with LAHNSCC who are not suitable for curative treatment.

Abstract
We propose and study a simple and innovative non-parametric approach to estimate the age-of-onset distribution for a disease from a cross-sectional sample of the population that includes individuals with prevalent disease. First, we estimate the joint distribution of two event times, the age of disease onset and the survival time after disease onset. We accommodate that individuals had to be alive at the time of the study by conditioning on their survival until the age at sampling. We propose a computationally efficient expectation-maximization (EM) algorithm and derive the asymptotic properties of the resulting estimates. From these joint probabilities we then obtain non-parametric estimates of the age-at-onset distribution by marginalizing over the survival time after disease onset to death. The method accommodates categorical covariates and can be used to obtain unbiased estimates of the covariate distribution in the source population. We show in simulations that our method performs well in finite samples even under large amounts of truncation for prevalent cases. We apply the proposed method to data from female participants in the Washington Ashkenazi Study to estimate the age-at-onset distribution of breast cancer associated with carrying BRCA1 or BRCA2 mutations.

Abstract
Coronal holes are areas on the Sun with open magnetic field lines. They are a source region of the solar wind, but how the wind emerges from coronal holes is not known. We observed a coronal hole using the Extreme Ultraviolet Imager on the Solar Orbiter spacecraft. We identified jets on scales of a few hundred kilometers, which last 20 to 100 seconds and reach speeds of ~100 kilometers per second. The jets are powered by magnetic reconnection and have kinetic energy in the picoflare range. They are intermittent but widespread within the observed coronal hole. We suggest that such picoflare jets could produce enough high-temperature plasma to sustain the solar wind and that the wind emerges from coronal holes as a highly intermittent outflow at small scales.

Abstract
Ionization of matter by energetic radiation generally causes complex secondary reactions that are hard to decipher. Using large helium nanodroplets irradiated by extreme ultraviolet (XUV) photons, we show that the full chain of processes ensuing primary photoionization can be tracked in detail by means of high-resolution electron spectroscopy. We find that elastic and inelastic scattering of photoelectrons efficiently induces interatomic Coulombic decay (ICD) in the droplets. This type of indirect ICD even becomes the dominant process of electron emission in nearly the entire XUV range in large droplets with radius ≳40 nm. Indirect ICD processes induced by electron scattering likely play an important role in other condensed-phase systems exposed to ionizing radiation as well, including biological matter.

INTRODUCTION Emphysematous pyelonephritis (EPN) is a deadly disease due to its associated morbidity and mortality. Attempts have been made to identify predictors of severity, mortality and need for nephrectomy in EPN with little success. METHODS We conducted an ambispective study of EPN patients between March 2014 and September 2019. Retrospective data were collected which included age, sex, comorbidities, symptoms, signs, laboratory investigations including imaging, need for dialysis, management and any complications. All patients were then followed prospectively for renal dynamic scan, stone surgery or nephrectomy. Univariate analysis was performed to identify factors affecting mortality and need for elective nephrectomy. RESULTS In total, 112 patients were included. Mean patient age was 50.01 years, 55% were female and 5% had bilateral involvement. Fever and flank pain were the most common symptoms. Diabetes was seen in 75% of cases and 30% of cases required haemodialysis at initial presentation. About 60% of patients improved with pigtail drainage. Need for nephrectomy was greater in Huang-Tseng stage 3a (14.8%). Huang-Tseng stages 3b and 4 had higher mortality rates (25%) than the other stages (2.2%). Twelve of 99 patients had non functional kidney on follow-up and underwent elective nephrectomy. Low platelet counts, high body mass index, septic shock, dialysis and higher Huang-Tseng stage were found to be predictive of mortality and renal parenchymal thickness on computed tomography scan was predictive of follow-up nephrectomy. CONCLUSIONS Thrombocytopaenia, high body mass index, septic shock, haemodialysis and higher Huang-Tseng stage are predictors of mortality and renal parenchymal thickness <5mm is a predictor of poor salvage of affected kidney on follow-up.

Abstract
Field emission of electrons underlies great advances in science and technology, ranging from signal processing at ever higher frequencies1 to imaging of the atomic-scale structure of matter2 with picometre resolution. The advancing of electron microscopy techniques to enable the complete visualization of matter on the native spatial (picometre) and temporal (attosecond) scales of electron dynamics calls for techniques that can confine and examine the field emission on sub-femtosecond time intervals. Intense laser pulses have paved the way to this end3,4 by demonstrating femtosecond confinement5,6 and sub-optical cycle control7,8 of the optical field emission9 from nanostructured metals. Yet the measurement of attosecond electron pulses has remained elusive. We used intense, sub-cycle light transients to induce optical field emission of electron pulses from tungsten nanotips and a weak replica of the same transient to directly investigate the emission dynamics in real time. Access to the temporal properties of the electron pulses rescattering off the tip surface, including the duration τ = (53 as ± 5 as) and chirp, and the direct exploration of nanoscale near fields open new prospects for research and applications at the interface of attosecond physics and nano-optics.

Abstract
INTRODUCTION: Patients with isoniazid (H, INH) resistant pulmonary TB but undetected rifampicin (R, RIF) resistance are treated with a 6-month regimen of levofloxacin-RIF-ethambutol-pyrazinamide (6LvxREZ) under India´s National TB Elimination Programme (NTEP).OBJECTIVE:
To describe the profile of and treatment outcomes in patients with pulmonary INH-resistant (INHR) TB initiated on TB treatment, and identify factors associated with unfavourable treatment outcomes (died, failed, treatment changed, lost to follow-up).METHODS: This was
a retrospective analysis of NTEP database (Ni-kshay) on pulmonary INHR TB patients initiated on treatment with “H mono/poly regimen” (6LvxREZ) between July 2019 and June 2020 with documented treatment outcomes. Proportions with 95% confidence interval (CI) was calculated
and logistic regression analysis was performed.RESULTS: Of the 11,519 patients with pulmonary INHR TB, 9,440 (82%) had treatment success (55.1% cured, 26.9% treatment completed). Unfavourable treatment outcome was observed in 1,901 (16.5%). Male sex, tobacco and alcohol
use, HIV reactive status were associated with unfavourable treatment outcome. Patients with katG mutations and resistance to fluoroquinolones were likely to have poor treatment outcomes.CONCLUSION: A levofloxacin-based regimen offers a treatment success rate of 82% in patients
with pulmonary INHR TB. Sex-specific strategies, interventions to address smoking and alcohol use, focus on HIV-reactive patients and optimising treatment regimens based on drug susceptibility should be considered for improving treatment outcomes.

Abstract
The present study demonstrates the spatial analysis and mapping of fish and different measures of environmental parameters and fish diversity of Pong reservoir, Himachal Pradesh, using Kriging spatial interpolation methods for geographical information system mapping. Seasonal data on environmental parameters, potential fish habitat and fish diversity was collected from lentic (dam), lentic (reservoir), transitional and lotic zone of the reservoir.. Important environmental parameters like water temperature, dissolved oxygen, electrical conductivity, water depth and transparency showed variations across the different zones of the reservoir. The sediment of the reservoir was sandy clay loam in nature as per texture analysis. Fish species richness, Shannon index and evenness index showed a similarity of the lotic and lentic (reservoir) zones of the reservoir. Six potential fish breeding grounds were identified in the reservoir indicating high conservation significance. The analysis of data showed a declining trend in fish production from 456.9 tonnes during the decade 1976-1987 to 347.91 tonnes during 2009-2020. The factors like anthropogenic climate change, predation of a stocked fish juvenile by water birds, undersized fish stocking and unscientific management are the probable reasons for the decreasing fish production. The spatial variation pattern of the water spread area, environmental parameters, fish catch and potential fish breeding grounds depicted in the GIS platform can be used as an important information base by the policy makers for fisheries management. The stocking of large size fish as a stocking material and adequate protection of the potential fish breeding grounds are the key advisories for the sustainable enhancement of fisheries as well as conservation.

Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Abstract
Renal cell cancer (RCC) commonly presents as an asymptomatic incidental mass on imaging for other abdominal pathologies. Because of its hypervascular nature, spontaneous haemorrhage, although very rare, can be seen with RCC. Spontaneous haemorrhage may present with flank pain, fever and sudden abdominal distension with or without haemorrhagic shock. Although unusual, spontaneous haemorrhage is potentially serious, and therefore clinicians should be aware of such events. Imaging may be difficult to interpret in view of intratumoral and perinephric haemorrhage. Prompt diagnosis and treatment is essential for a successful outcome. We report a case of massive intratumoral bleed in RCC in a young male and its management by renal artery angioembolisation followed by radical nephrectomy.

Abstract
Purpose: The transition from office to work-from-home (WFH) has lead to an increased interest in the effects of this transition, not only on the quality of work obtained but also on the mental health of individuals. Research in this topic is expanding with different perspectives in focus. This review aims to identify the significant factors influenced by WFH and the consequential effects on working parents. Methodology: To write this review, 4 databases are being explored - SCOPUS, Emerald, EBSCO, and Web of Science. Papers reviewed are selected using the keywords work from home, well-being, mental health, work-life balance, and family combined with parents, family, working mother, or working father. The papers have been selected for the past 25 years. An attempt is being made to review at least 53 articles. Findings/Theoretical Implications: This paper will highlight the advantages and disadvantages parents face while balancing work and family. The review will give a comprehensive impression of the mental health state of working parents. Value: The study will enable future researchers to identify currently unexplored issues and design their studies based on the same.

Abstract
The fragmentation dynamics of the gas-phase, doubly charged camphor molecule, formed by Auger decay following carbon 1s ionisation, using soft X-ray synchrotron radiation, is presented in this work. The technique of velocity map imaging combined with a photoelectron-photoion-photoion coincidence (VMI-PEPIPICO) is used for both electron energy and ion momentum (in-sequence) measurements. The experimental study is complemented by molecular dynamics simulation, performed with an NVT (moles, volume, and temperature) ensemble. Velocity Verlet algorithms were used for time integration at various internal energies. These simulations validate observed dissociation pathways. From these, we successfully deduce that the internal energy of the doubly charged molecular ion has a significant contribution to the fragmentation mechanism. Notably, a prominent signature of the internal energy was observed in the experimentally determined energies of the neutral fragment in these deferred charge separation pathways, entailing a more detailed theoretical study to uncover the exact dissociation dynamics.

Abstract
The acetylene-vinylidene system serves as a benchmark for investigations of ultrafast dynamical processes where the coupling of the electronic and nuclear degrees of freedom provides a fertile playground to explore the femto- and sub-femto-second physics with coherent extreme-ultraviolet (EUV) photon sources both on the table-top as well as free-electron lasers. We focus on detailed investigations of this molecular system in the photon energy range 19-40 eV where EUV pulses can probe the dynamics effectively. We employ photoelectron-photoion coincidence (PEPICO) spectroscopy to uncover hitherto unrevealed aspects of this system. In this work, the role of excited states of the C2H2+ cation, the primary photoion, is specifically addressed. From photoelectron energy spectra and angular distributions, the nature of the dissociation and isomerization channels is discerned. Exploiting the 4π-collection geometry of the velocity map imaging spectrometer, we not only probe pathways where the efficiency of photoionization is inherently high but also perform PEPICO spectroscopy on relatively weak channels.

Abstract
This work presents the results from the characterization of a Position-Sensitive Planar Germanium (PSPGe) detector. The PSPGe detector is a double-sided orthogonal strip detector consisting of 10x10 electrical segmentation along the horizontal and vertical directions. The characterization was performed using the coincidence setup between the PSPGe detector and the well-characterized scanning system employing the positron annihilation correlation principle. The scanning system consists of a Position Sensitive Detector (PSD) and 22Na positron source. The main objective of this study is to deploy PSPGe detector for future decay experiments at the Facility for Antiproton and Ion Research (FAIR), Germany. The measurements have been performed to find the depth of gamma-ray interaction in the planar segmented detector. The 2-Dimensional image obtained from the PSD has been used to find the depth of gamma-ray interaction in the planar strip detector using pulse shape analysis. In addition, the sensitivity of PSPGe detector has been investigated by calculating the rise-time from pulse shapes for the front and back strips of the detector.

Abstract
A series of substituted 4-{1-aza-2-[(aryl) amino)]}-3-methyl-2-pyrazolin-5-ones has been synthesized and evaluated for their biological activity. The title compounds (4a-l) were prepared by the diazotization of substituted anilines (1a-l) to form substituted phenyl hydrazine derivatives (2a-l) which synthesized substituted 4-{1-aza-2-[(aryl) amino)]}-3-methyl-2-pyrazolin-5-ones (4a-l) by Michael addition reaction, which is a nucleophilic addition of enolate anion to the carbon-carbon double bond of a α, β–unsaturated carboxylic acid derivatives. Twelve different pyrazolinone derivatives (4a to 4l) were synthesized. Structural assignments of these compounds have been made by elemental analysis, FTIR, 1HNMR and Mass spectral data and the purity of the compounds was determined by TLC. The antifeedant activity of the newly isolated heterocyclic compounds was evaluated against agriculture pest Achoea janata. Compound 4d found to be very effective as antifeedant while rest of the compounds showed a moderate to good degree of antifeedant activity.

Abstract
We consider exciton polaritons in a zigzag chain of coupled elliptical micropillars subjected to incoherent excitation. The driven-dissipative nature of the system along with the naturally present polarization splitting inside the pillars gives rise to nonreciprocal dynamics, which eventually leads to the non-Hermitian skin effect, where all the modes of the system collapse to one edge. As a result, the polaritons propagate only in one direction along the chain, independent of the excitation position, and the propagation in the opposite direction is suppressed. The system shows robustness against disorder and, using the bistable nature of polaritons to encode information, we show one-way information transfer. This paves the way for compact and robust feedback-free one-dimensional polariton transmission channels without the need for external magnetic field, which are compatible with proposals for polaritonic circuits.

Abstract
Introduction Liver transplantation is an important measure of burden from hepatitis C virus (HCV)-associated liver disease. Aims To describe transplant rates and survival in individuals with HCV infection from 2008 to 2017 in England through data linkage. Methods This is a retrospective observational cohort study. Laboratory reports of HCV infection were linked to the Liver Transplant Registry for individuals aged 15 years and over, first diagnosed between 1998 and 2017. We estimated age-sex standardised incidence rates and used Poisson regression to investigate predictors of liver transplantation and test for a change in incidence after introduction of direct-acting antivirals (DAAs) in 2014. Kaplan-Meier survival analysis was used to calculate post-transplant survival rates. Results Of 124,238 individuals diagnosed with HCV infection, 1,480 were registered and 1,217 received a liver transplant. Of individuals registered, 1,395 had post-HCV cirrhosis and 636 had hepatocellular carcinoma (618 also had post-HCV cirrhosis). Median time from HCV diagnosis to transplant was 3.4 years (interquartile range: 1.3–6.8 years). Liver transplant rates were lower 2014–17 compared with 2011–13 (incidence rate ratio: 0.64; 95% confidence interval: 0.55–0.76). Survival rates were 93.4%, 79.9% and 67.9% at 1, 5 and 10 years, respectively. Data linkage showed minimal under-reporting of HCV in the transplant registry. Conclusion In the post-DAA era, liver transplant rates have fallen in individuals with HCV infection, showing early impact of HCV treatment scale-up; but the short time from HCV diagnosis to liver transplant suggests late diagnosis is a problem.

Abstract
Embedded atoms or molecules in a photoexcited He nanodroplet are well-known to be ionized through inter-atomic relaxation in a Penning process. In this work, we investigate the Penning ionization of acetylene oligomers occurring from the photoexcitation bands of He nanodroplets. In close analogy to conventional Penning electron spectroscopy by thermal atomic collisions, the n = 2 photoexcitation band plays the role of the metastable atomic 1s2s 3,1S He*. This facilitates electron spectroscopy of acetylene aggregates in the sub-Kelvin He environment, providing the following insight into their structure: the molecules in the dopant cluster are loosely bound van der Waals complexes rather than forming covalent compounds. In addition, this work reveals a Penning process stemming from the n = 4 band where charge-transfer from autoionized He in the droplets is known to be the dominant relaxation channel. This allows for excited states of the remnant dopant oligomer Penning-ions to be studied. Hence, we demonstrate Penning ionization electron spectroscopy of doped droplets as an effective technique for investigating dopant oligomers which are easily formed by attachment to the host cluster.

Abstract
BACKGROUND We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2012 to December 2017 in 523 intensive care units (ICUs) in 45 countries from Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS During the 6-year study period, prospective data from 532,483 ICU patients hospitalized in 242 hospitals, for an aggregate of 2,197,304 patient days, were collected through the INICC Surveillance Online System (ISOS). The Centers for Disease Control and Prevention-National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI) were applied. RESULTS Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the medical-surgical ICUs, the pooled central line-associated bloodstream infection rate was higher (5.05 vs 0.8 per 1,000 central line-days); the ventilator-associated pneumonia rate was also higher (14.1 vs 0.9 per 1,000 ventilator-days,), as well as the rate of catheter-associated urinary tract infection (5.1 vs 1.7 per 1,000 catheter-days). From blood cultures samples, frequencies of resistance, such as of Pseudomonas aeruginosa to piperacillin-tazobactam (33.0% vs 18.3%), were also higher. CONCLUSIONS Despite a significant trend toward the reduction in INICC ICUs, DA-HAI rates are still much higher compared with CDC-NHSN's ICUs representing the developed world. It is INICC's main goal to provide basic and cost-effective resources, through the INICC Surveillance Online System to tackle the burden of DA-HAIs effectively.

Abstract
Recently realized higher order topological insulators have taken a surge of interest among the theoretical and experimental condensed matter community. The two-dimensional second order topological insulators give rise to zero-dimensional localized corner modes that reside within the band gap of the system along with edge modes that inhabit a band edge next to bulk modes. Thanks to the topological nature, information can be trapped at the corners of these systems, which will be unhampered even in the presence of disorder. Being localized at the corners, the exchange of information among the corner states is an issue. Here we show that the nonlinearity in an exciton polariton system can allow the coupling between the different corners through the edge states based on optical parametric scattering, realizing a system of multiple connectible topological modes.

Abstract
This study was aimed to compare the long-term outcomes and survival rate among mitral valve replacement using thoracotomy and standard median sternotomy in a single surgeon's practice. Total 250 patients were evaluated; Group I (n=65) patients had anterolateral thoracotomy and Group II (n=185) had standard median sternotomy for valve replacement. Mean age was 25.1±5 years in Group I and 41.8±10.5 years in Group II. Female was predominant in Group I. Total operative time and bypass time was statistically significant in Group I (235.5±25.8 minutes; 84.2±12.75 minutes) in contrast to Group II (203.8±15.5 minutes; 71.5±10.5 minutes). Incision scar was not visible in females in Group I but full incision scar was visible in Group II. Post-operative ICU stay duration was significant high in Group II. Though, wound infection incidence was 0% in Group I; however, 9.73% patient had wound infection in Group II. Only 1.62% patient developed unstable sternum in Group II. Most of the patients from both study group were in regular follow up and 1-year mortality rate was 4.62% and 5.94% in Group I and Group II respectively. Mitral valve replacement through a right anterolateral thoracotomy is easy and safe to perform; while getting maximum benefits for the patients. Besides satisfactory cosmetic outcome especially in female, this approach provides better exposure to mitral apparatus even in patients with small left atrium, cost effectiveness, less duration of hospital stays and absence of the risk for unstable sternum.
