Isolated testicular relapse in acute lymphoblastic leukemia - Effective treatment with the modified CCG-112 protocol
BACKGROUND: The testes have been considered a sanctuary site for
leukemic cells and testicular relapses used to account for a major
proportion of the poor outcome of boys with acute lymphoblastic
leukemia. With use of aggressive chemotherapy which includes
intermediate or high dose methotrexate, the incidence of testicular
relapses has declined. However once these patients have received
cranial irradiation as a part of the front line protocol, high dose
methotrexate needs to be avoided because of risk of developing
leucoencephalopathy. AIM: To study the use of non cross resistant
chemotherapeutic agents along with a regimen containing lower doses of
methotrexate in patients of isolated testicular relapse (ITR).
MATERIALS AND METHODS: This is a retrospective analysis of 12
consecutive patients with ITR treated with modified version of the
CCG-112 protocol which consists of intensive systemic chemotherapy,
cranial chemoprophylaxis along with testicular irradiation. RESULTS:
One patient died of regimen related toxicity. Two patients relapsed in
the bone marrow during maintenance. Of the nine patients who completed
treatment, eight are alive and in remission. One patient had a bone
marrow relapse two months after completing treatment. The Kaplan Meier
estimates give us an Event Free Survival (EFS) of 66.7% at 10 yrs.
CONCLUSIONS: Thus, though the incidence is very low, patients with ITR
should be treated aggressively since they have an excellent chance of
achieving a long term EFS
LEARN: A multi-centre, cross-sectional evaluation of Urology teaching in UK medical schools
OBJECTIVE: To evaluate the status of UK undergraduate urology teaching against the British Association of Urological Surgeons (BAUS) Undergraduate Syllabus for Urology. Secondary objectives included evaluating the type and quantity of teaching provided, the reported performance rate of General Medical Council (GMC)-mandated urological procedures, and the proportion of undergraduates considering urology as a career. MATERIALS AND METHODS: LEARN was a national multicentre cross-sectional study. Year 2 to Year 5 medical students and FY1 doctors were invited to complete a survey between 3rd October and 20th December 2020, retrospectively assessing the urology teaching received to date. Results are reported according to the Checklist for Reporting Results of Internet E-Surveys (CHERRIES). RESULTS: 7,063/8,346 (84.6%) responses from all 39 UK medical schools were included; 1,127/7,063 (16.0%) were from Foundation Year (FY) 1 doctors, who reported that the most frequently taught topics in undergraduate training were on urinary tract infection (96.5%), acute kidney injury (95.9%) and haematuria (94.4%). The most infrequently taught topics were male urinary incontinence (59.4%), male infertility (52.4%) and erectile dysfunction (43.8%). Male and female catheterisation on patients as undergraduates was performed by 92.1% and 73.0% of FY1 doctors respectively, and 16.9% had considered a career in urology. Theory based teaching was mainly prevalent in the early years of medical school, with clinical skills teaching, and clinical placements in the later years of medical school. 20.1% of FY1 doctors reported no undergraduate clinical attachment in urology. CONCLUSION: LEARN is the largest ever evaluation of undergraduate urology teaching. In the UK, teaching seemed satisfactory as evaluated by the BAUS undergraduate syllabus. However, many students report having no clinical attachments in Urology and some newly qualified doctors report never having inserted a catheter, which is a GMC mandated requirement. We recommend a greater emphasis on undergraduate clinical exposure to urology and stricter adherence to GMC mandated procedures
Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries
Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
PANC Study (Pancreatitis: A National Cohort Study): national cohort study examining the first 30 days from presentation of acute pancreatitis in the UK
Abstract
Background
Acute pancreatitis is a common, yet complex, emergency surgical presentation. Multiple guidelines exist and management can vary significantly. The aim of this first UK, multicentre, prospective cohort study was to assess the variation in management of acute pancreatitis to guide resource planning and optimize treatment.
Methods
All patients aged greater than or equal to 18 years presenting with acute pancreatitis, as per the Atlanta criteria, from March to April 2021 were eligible for inclusion and followed up for 30 days. Anonymized data were uploaded to a secure electronic database in line with local governance approvals.
Results
A total of 113 hospitals contributed data on 2580 patients, with an equal sex distribution and a mean age of 57 years. The aetiology was gallstones in 50.6 per cent, with idiopathic the next most common (22.4 per cent). In addition to the 7.6 per cent with a diagnosis of chronic pancreatitis, 20.1 per cent of patients had a previous episode of acute pancreatitis. One in 20 patients were classed as having severe pancreatitis, as per the Atlanta criteria. The overall mortality rate was 2.3 per cent at 30 days, but rose to one in three in the severe group. Predictors of death included male sex, increased age, and frailty; previous acute pancreatitis and gallstones as aetiologies were protective. Smoking status and body mass index did not affect death.
Conclusion
Most patients presenting with acute pancreatitis have a mild, self-limiting disease. Rates of patients with idiopathic pancreatitis are high. Recurrent attacks of pancreatitis are common, but are likely to have reduced risk of death on subsequent admissions.

31st Annual Meeting and Associated Programs of the Society for Immunotherapy of Cancer (SITC 2016) : part two
Background
The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd.
Methods
We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background.
Results
First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001).
Conclusions
In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival
Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19
IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19.
Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19.
DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 nonâcritically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022).
INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (nâ=â257), ARB (nâ=â248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; nâ=â10), or no RAS inhibitor (control; nâ=â264) for up to 10 days.
MAIN OUTCOMES AND MEASURES The primary outcome was organ supportâfree days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes.
RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ supportâfree days among critically ill patients was 10 (â1 to 16) in the ACE inhibitor group (nâ=â231), 8 (â1 to 17) in the ARB group (nâ=â217), and 12 (0 to 17) in the control group (nâ=â231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ supportâfree days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively).
CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

Closet drinkers: Alcohol use disorder among women in Delhi
This article is based on a study on alcohol consumption among Indian women. The available data on women alcoholics is scarce and veiled under the stereotypical image of the ârighteousâ Indian woman. Indian society frowns upon women who drink, forcing them to remain closet drinkers. The participants of this research study comprised a total of ten women and two key informants. The study found that alcoholism among women is an emerging issue of concern and that there is a dearth of rehabilitation facilities exclusively catering to women. For a better understanding of the pattern, profile and nature of the problem, more studies in the field need to be encouraged
Lipid Accumulation Product as a Marker of Cardiovascular Disease Risk among Women with Polycystic Ovarian Syndrome- A Hospital Based Case-control Study
Introduction: Polycystic Ovarian Syndrome (PCOS) is the most
frequent gynaecological endocrinopathy characterised mainly
by anovulation and hyperandrogenism. Women with PCOS
are at higher risk of developing Cardiovascular Disease (CVD)
due to a number of risk factors associated with this disease.
Obesity, especially central adipose tissue accumulation, plays
a major role in the pathophysiology of this disease. Lipid
Accumulation Product (LAP) is a simple, inexpensive index to
estimate cardiovascular risk and is based on fasting triglyceride
and Waist Circumference (WC).
Aim: To find out the association between LAP and cardiovascular
risk factors in women with PCOS.
Materials and Methods: This case-control study was
conducted in the Department of Biochemistry and
Department of Gynaecology, Government Medical College,
Thiruvananthapuram, Kerala, India. Study subjects included
48 women with PCOS and 48 age and Body Mass Index (BMI)
matched controls. Clinical and demographic data and medical
history were evaluated. Duration of the study was six months.
Anthropometric measurements, Blood Pressure (BP) and
biochemical parameters like Fasting Plasma Glucose (FPG), lipid
profile were recorded. LAP was calculated using the formulaFemale LAP= {waist (cm) -58} Ă Triglyceride (TG) concentration
(mmol/L). The quantitative variables were expressed as mean
and standard deviation. Comparison of continuous variables
between two groups was analysed by unpaired t-test. Categorical
variables were analysed by Chi-square test. Correlations between
continuous variables were tested using the Pearson correlation or
Spearman correlation coefficient (r) analysis. The p-value <0.05
was considered as statistically significant. Variables which were
statistically significant in univariate analysis were subjected to
multivariate analysis.
Results: The results of this study showed that the PCOS
group had significantly higher WC than BMI matched control
group. PCOS group had significantly higher mean TG level
(p<0.05), mean FPG level (p<0.05) and lower mean High
Density Lipoprotein (HDL) level (p<0.05) than the control
group. LAP value (p<0.001) was significantly higher in PCOS
group compared to control group. The prevalence of Metabolic
Syndrome (MetS) was higher in women with PCOS. LAP values
too were significantly higher in PCOS women with MetS. All CVD
risk parameters except age showed a significant relationship
with LAP values. Multiple linear regression model was done and
LAP (p<0.001) was found to be an independent risk factor for
CVD, adjusting for other factors.
Conclusion: The study results shows that there is a significant
association between LAP and cardiovascular risk markers. High
LAP index is associated with cardiovascular risk markers in
PCOS women irrespective of obesity
