Acquired gene alterations in patients treated with ribociclib plus endocrine therapy or endocrine therapy alone using baseline and end-of-treatment circulating tumor DNA samples in the MONALEESA-2, -3, and -7 trials. Ann Oncol 2025; 36:54-64. [PMID: 39313156 DOI: 10.1016/j.annonc.2024.09.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2024] [Revised: 09/12/2024] [Accepted: 09/14/2024] [Indexed: 09/25/2024] Open
Abstract
BACKGROUND A prior pooled analysis of the MONALEESA-2, -3, and -7 trials identified baseline markers predictive of sensitivity or resistance to ribociclib plus endocrine therapy (ET). We report the results of an analysis of paired baseline and end-of-treatment (EOT) circulating tumor DNA (ctDNA) samples across the MONALEESA trials. PATIENTS AND METHODS Paired baseline and EOT ctDNA samples from MONALEESA-2, -3, and -7 were sequenced using a targeted next-generation sequencing panel. Genes with an EOT alteration prevalence of >5% were included. A McNemar test was carried out on paired samples and adjusted for multiple testing to control the false discovery rate. A Bayesian mixed-effects model was used to adjust for ctDNA fraction at both time points and for study differences. RESULTS The analysis included 523 paired samples. At EOT, 21 genes had a >5% alteration prevalence. A trend for higher ctDNA fraction at EOT versus baseline (P = 0.08) was observed. Prevalence of alterations was higher at EOT versus baseline in RB1, SPEN, TPR, PCDH15, and FGFR2 in the ribociclib arm; PBRM1 in the placebo arm; and ESR1 in both arms. The mixed-effects model demonstrated that the same trends for increased prevalence of these alterations at EOT were observed after adjusting for ctDNA fraction and that the increased rate of RB1 and SPEN alterations at EOT were specific to ribociclib plus ET. Analysis of ESR1 indicated a similar increase at EOT in both arms. The most common acquired ESR1 mutations at EOT included Y537C/N/S/D, D538G, E380Q, and L536H/R/P/LC. The prevalence of PIK3CA hotspot mutations at baseline and EOT was similar. CONCLUSIONS This analysis identified acquired gene alterations in patients with hormone receptor-positive/human epidermal growth factor receptor-2 negative advanced breast cancer treated with ribociclib plus ET or placebo plus ET. These data may support further studies on acquired resistance mechanisms and inform future systemic interventions in the post-cyclin-dependent kinase 4/6 inhibitor setting.

Abstract
In this work, bovine serum albumin (BSA) and Aspergillus sp. laccase (LC) were encapsulated in situ within two lanthanide-based MOFs (TbBTC and GdBTC) through a green one-pot synthesis (almost neutral aqueous solution, T = 25 °C, and atmospheric pressure) in about 1 h. Pristine MOFs and protein-encapsulated MOFs were characterized through wide angle X-ray scattering, scanning electron microscopy, thermogravimetric analysis, Fourier transform infrared and Raman spectroscopies. The location of immobilized BSA molecules, used as a model protein, was investigated through small angle X-ray scattering. BSA occurs both on the inner and on the outer surface of the MOFs. LC@TbBTC, and LC@GdBTC samples were also characterized in terms of specific activity, kinetic parameters, and storage stability both in water and acetate buffer. The specific activity of LC@TbBTC was almost twice that of LC@GdBTC (10.8 μmol min-1 mg-1vs. 6.6 μmol min-1 mg-1). Both biocatalysts showed similar storage stabilities retaining ∼60% of their initial activity after 7 days and ∼20% after 21 days. LC@TbBTC dispersed in acetate buffer exhibited a higher storage stability than LC@GdBTC. Additionally, terbium-based MOFs showed interesting luminescent properties. Together, these findings suggest that TbBTC and GdBTC are promising supports for the in situ immobilization of proteins and enzymes.

J Family Med Prim Care 2024; 13:2647-2652.

Abstract
Background Co-existing iron deficiency in patients of sickle cell disease (SCD) and trait may worsen anemia, and adversely affect neuro-cognitive development and growth. Determining a cut-off below which Mean corpuscular Volume (MCV) can predict iron deficiency in SCD patients can preclude use of more expensive test serum ferritin. Aims This study was conducted to determine the diagnostic accuracy of low MCV in detecting iron deficiency compared to serum ferritin levels in patients with SCD. Methods 60 consecutive patients with SS or AS pattern on hemoglobin electrophoresis were enrolled. The index test (MCV) and the reference standard test (serum ferritin) were performed in a blind and independent manner. The measures of diagnostic accuracy were calculated and the precision of the point estimates were expressed by 95% confidence intervals. As MCV is a continuous variable, we also used multi-level likelihood ratios to compute diagnostic accuracy of MCV at several cut-points. Results The sensitivity of low MCV in detecting iron deficiency was 40.0% (95% CI-20.0-63.6), the specificity was 78.4% (95% CI-61.3-89.6) using serum ferritin as a reference standard. The sensitivity and specificity of predicting coexisting iron deficiency at this point was 60.9% (CI-38.6-80.3%) and 75.7% (CI-58.8-88.2%) respectively. Conclusions The low sensitivity (40%) of microcytosis in detecting iron deficiency indicates that many cases will be missed if MCV alone is used to detect co-existing iron deficiency anemia in SCD patients. No single test is good enough to detect co-existing iron deficiency and a combination of tests might be useful.

Abstract
We present a novel perspective on thinking about and studying healthcare spending in contexts where few health-related financial risk protection mechanisms exist and where out-of-pocket spending by households is the norm. Drawing on interviews conducted across 20 villages in two states of India, we illustrate and problematize how a complex interplay of social norms and cultural factors underpin spending decisions within households in such contexts. While our analysis draws on the fieldwork at large, we present our findings through selected narratives - stories of patients suffering from chronic breathlessness. We engage with and reveal the various ways in which social norms dynamically drive this household economy, and shape resource allocation-related decisions. We conclude that in health system contexts where out-of-pocket spending by households is the norm, it is essential to recognise the pragmatic and calculative nature of intra-household allocation of resources, and how it involves bargaining and negotiations at the intersection of social norms, economic class, caste, gender, age, and productive status. And at the same time, how all of this occurs within the economy of the family, and how it plays out differently for different members of a family is also important to recognise. Such recognition can not only help one better appreciate how this household level economy may sometimes maintain and perpetuate entrenched hierarchies and gender inequities, crucially, it can help target health related social protection policies and strategies and make them more responsive to the needs of the most vulnerable in the society and within households.

Abstract
Vitamin D plays a vital role in regulating calcium and phosphate metabolism and maintaining bone health. A state of prolonged or profound vitamin D deficiency (VDD) can result in rickets in children and osteomalacia in children and adults. Recent studies have demonstrated the pleiotropic action of vitamin D and identified its effects on multiple biological processes in addition to bone health. VDD is more prevalent in chronic childhood conditions such as long-standing systemic illnesses affecting the renal, liver, gastrointestinal, skin, neurologic and musculoskeletal systems. VDD superimposed on the underlying disease process and treatments that can adversely affect bone turnover can all add to the disease burden in these groups of children. The current review outlines the causes and mechanisms underlying poor bone health in certain groups of children and young people with chronic diseases with an emphasis on the proactive screening and treatment of VDD.

Abstract
Drawing on interviews conducted in 2019–2020, across twenty villages in India, this paper unpacks how people with chronic illness navigate complex care-seeking terrain. We show how the act of seeking care involves navigating through personal, family, social, economic, cultural, and most importantly, difficult health systems spaces—and entails making difficult social, moral, and financial choices. We show how the absence of reliable and accessible points of first contact for primary care results in people running from pillar to post, taking wrong turns, and becoming disappointed, frustrated, and, sometimes, impoverished. We reveal the complex individual and social dynamics of hope and misplaced and misguided expectations, as well as social obligations and their performance that animate the act of navigating care in rural India. We shine light on how a health system with weak primary care and poor regulation amplifies the medical, social, and financial consequences of an otherwise manageable chronic illness, and how these consequences are the worst for those with the least social, network and economic capital. Crucially we highlight the problematic normalisation of the absence of reliable primary care services for chronic illness in India, in rural India specifically. We signpost implications for research, and for policy and practice in India and similar health system contexts, i.e. those with weak primary care and poor regulation of the private sector. We argue that in India, having in place accessible, good quality, and trustworthy sources of advice and care for chronic illness at the first point of call, for all, is critical. We contend that this first point of call should be quality, public primary care services. We conclude that if such arrangements are in place in public services, people will use them.
Lack of reliable, trustworthy advice and care is a big gap in India's health system. Being misled and suffering catastrophic consequences of ill-health is the result. People need to be protected from bad actors in their care-seeking journeys. People want reliable, trustworthy advice and care, at their first point of call. India's health system must urgently act to ensure appropriate care at all levels.

Abstract
BackgroundNowadays 80% of internet users access health information online, with YouTube being the second most popular search website worldwide. This study was undertaken to assess the reliability and quality of videos pertaining to myositis on YouTube and identify lacunae in information material on the platform.ObjectivesThis study aims to assess the quality and profile of myositis information videos on YouTube, and to compare and delineate attributes of useful and not useful videos using standard metrics.MethodsA thorough search was carried out on YouTube using 9 search terms related to myositis. The inclusion criteria were primary English content related to myositis, acceptable audio-video quality, and multi-part videos to be considered as one, while duplicates and advertisements were excluded. The videos were classified as useful, not useful or misleading, and patient experiences (Figure 1).Figure 1.Flowchart of selection of YouTube videos for the studyReliability of the videos was determined using the 5-point modified DISCERN (mDISCERN) criteria and quality by the 5-point Global Quality Scale (GQS) and 4-point JAMA scoring system. Score-based usefulness was defined as mDISCERN >4 or GQS >4 or JAMA >3. All values are in median and IQR.ResultsOf 453 analyzed videos 74% and 2% provided useful and not useful information respectively. 24% were patient experiences, and 324 (71%) were intended specifically for patients while 313 (69%) were for healthcare providers and students. Nearly one-thirds (n=143) reported information related to treatment of myositis.Noteworthily, useful and not useful videos had similar views count. However, number of likes and daily viewership were higher for useful videos (p=0.024, p=0.046). Nearly half (47%) of useful videos were by professional medical societies/patient support groups while not useful ones were often by nonmedical media (38%).Useful videos had higher mDISCERN reliability scores [4(3-4) vs 2(1-3), p<0.001] and better quality on GQS [4.5 (3.5-5) vs 1 (1-2.8), p<0.001] and JAMA [3 (3-4) vs 2.25 (2-3), p=0.004]. Physician predicted usefulness was discordant with score-based usefulness(κ=0.129). However, GQS score emerged significant (p=0.008) for predicting video usefulness in multivariate analysis (Table 1).Table 1.Factors predicting usefulness of video in binary logistic regression.VariableB coefficientS.E.Exp (B) and 95% CIp valueIntended audience Anyone/General public-5.452.5860.004 (0.0-0.68)0.035Average GQS-2.861.0760.05 (0.007-0.47)0.008GQS Global Quality Scale.

However, the dynamic nature of YouTube could potentially change this equation in the future and physicians should correct any misinformation identified in face-to-face meetings or teleconsultations. High quality useful videos, often predicted by validated scores and produced by professional medical societies should be promoted as the first line of content consumed.Disclosure of InterestsNone declared

Abstract
OBJECTIVE We evaluated effect of sequentially introducing four WHO-recommended interventions to promote hand-hygiene compliance in tertiary-care NICU. STUDY DESIGN Four dedicated research nurses directly observed doctors and nurses to record success in hand-hygiene opportunities at randomly selected NICU beds and randomly sampled time-slots in four phases (of 4-weeks each): I-Baseline, II-Self-directed learning; III-Participatory learning; IV-Closed-Circuit Television (CCTV); and V-CCTV-plus (with feedback). FINDINGS Hand-hygiene compliance changed from 61.8% (baseline) to 77% (end) with overall relative change: 24.6% (95% CI 18, 32; p value= 0.003); compared with preceding phase, relative changes of 21% (15, 28; <0.001), 4% (0, 8; 0.008), -10% (-13, -6; <0.001), and 10% (5, 15; <0.001) during phases II, III, IV, and V, respectively were observed. Rise in hand-hygiene compliance was higher for after-WHO-moments (12.7%; upto 2.5-folds for moment 5, <0.001) compared to before-WHO-moments (5.2%). Educational interventions, feedback and monitoring WHO moments can improve hand-hygiene compliance significantly among health-care providers in NICU.

Abstract
CONTEXT Physical activity is an important factor for healthy aging, and lack of it has been associated with chronic noncommunicable diseases (NCDs). Research in sedentary behavior has indicated that it is an independent risk factor of morbidity and mortality, separate from lack of physical activity. METHODS This cross-sectional study was conducted in the department of medicine in a tertiary care hospital on apparently healthy relatives of patients without chronic NCDs. Metabolic equivalents of tasks (METs) were calculated by the global physical activity questionnaire (GPAQ). STATISTICAL ANALYSIS We correlated the various parameters [age, sex, body mass index (BMI), waist-hip ratio (WHR), and lipid panel with METs] by Pearson correlation coefficient. OBSERVATIONS AND RESULTS Total of 750 patients with a mean age of 42.55 ± 10.93 years were included, and 389 (51.9%) were male in the present study. In our study, a strong negative correlation was found between physical activity and BMI, moderate negative correlation between physical activity with triglycerides (TG), total cholesterol (TC), and WHR. There was a high degree of positive correlation between sedentary lifestyle (SLS) duration with BMI and TC. A moderate degree positive correlation was found between SLS duration and WHR, TG, and low-density lipoproteins (LDL). CONCLUSION The clinician should be aware of various obesity indices, and it was found that lipid profile is inversely correlated with physical activity and directly correlated with SLS in healthy individuals. Lifestyle changes and exercise may reduce obesity and lipid disorders and thereby reduce further development of complications in those patients.

Abstract
BACKGROUND AND PURPOSE Infarct volume is an important predictor of clinical outcome in acute stroke. We hypothesized that the association of infarct volume and clinical outcome changes with the magnitude of infarct size. MATERIALS AND METHODS Data were derived from the Safety and Efficacy of Nerinetide in Subjects Undergoing Endovascular Thrombectomy for Stroke (ESCAPE-NA1) trial, in which patients with acute stroke with large-vessel occlusion were randomized to endovascular treatment plus either nerinetide or a placebo. Infarct volume was manually segmented on 24-hour noncontrast CT or DWI. The relationship between infarct volume and good outcome, defined as mRS 0-2 at 90 days, was plotted. Patients were categorized on the basis of visual grouping at the curve shoulders of the infarct volume/outcome plot. The relationship between infarct volume and adjusted probability of good outcome was fitted with linear or polynomial functions as appropriate in each group. RESULTS We included 1099 individuals in the study. Median infarct volume at 24 hours was 24.9 mL (interquartile range [IQR] = 6.6-92.2 mL). On the basis of the infarct volume/outcome plot, 4 infarct volume groups were defined (IQR = 0-15 mL, 15.1-70 mL, 70.1-200 mL, >200 mL). Proportions of good outcome in the 4 groups were 359/431 (83.3%), 219/337 (65.0%), 71/201 (35.3%), and 16/130 (12.3%), respectively. In small infarcts (IQR = 0-15 mL), no relationship with outcome was appreciated. In patients with intermediate infarct volume (IQR = 15-200 mL), there was progressive importance of volume as an outcome predictor. In infarcts of > 200 mL, outcomes were overall poor. CONCLUSIONS The relationship between infarct volume and clinical outcome varies nonlinearly with the magnitude of infarct size. Infarct volume was linearly associated with decreased chances of achieving good outcome in patients with moderate-to-large infarcts, but not in those with small infarcts. In very large infarcts, a near-deterministic association with poor outcome was seen.

Abstract
Objectives Dolutegravir (DTG) is widely recommended within three‐drug regimens. However, similar efficacy and tolerability have also been achieved with DTG within two‐drug regimens in clinical trials. This study evaluated the real‐world effectiveness and discontinuations in people living with HIV‐1 (PLHIV) switching to DTG with lamivudine (3TC) or rilpivirine (RPV). Methods This was a one‐arm meta‐analysis utilizing data from a systematic literature review. Data from real‐world evidence studies of DTG + RPV and DTG + 3TC were extracted, pooled and analysed. The primary outcome was the proportion of patients with viral failure (VF; ≥ 50 copies/mL in two consecutive measurements and/or ≥ 1000 copies/mL in a single measurement) at week 48 (W48) and week 96 (W96). Other outcomes included virological suppression (VS; < 50 copies/mL) and discontinuations (W48 and W96). Estimates were calculated for VF, VS as per snapshot (VSS) and on treatment analysis (VSOT), and discontinuations. Results Pooled mean estimates of VF for DTG + 3TC and DTG + RPV were 0.8% [95% confidence interval (CI): 0.4–1.3] and 0.6% (95% CI: 0.0–1.6), respectively, at W48. VSS rate at W48 was 85.0% (95% CI: 82.3–87.5) for DTG + 3TC regimen and 92.4% (95% CI: 85.0–97.7) in the DTG + RPV regimen. The DTG + 3TC and DTG + RPV regimens led to discontinuations in 13.6% (95% CI: 11.1–16.2) and 7.2% (95% CI: 2.1–14.4) of patients, respectively, at W48. Similar results were observed at W96. Conclusions Treatment with DTG + 3TC or DTG + RPV in clinical practice provides a low rate of VF and a high rate of VS when initiated in virologically suppressed PLHIV with diverse backgrounds.

Abstract
Invitro maturation (IVM) of oocytes is a crucial step and is directly related to better embryo production in buffaloes. Therefore, we planned to study gene expression of GDF9, HAS2, SPRY1, ARHGAP22, COL18A1, and GPC4 genes in IVM and immature cumulus–oocyte complexes (COCs). The COCs were recovered from follicles of slaughter origin ovaries of native buffaloes. COCs were observed under stereo zoom microscope and categorized in four grades according to morphology. Of the four grades, the first three grade COCs were considered and randomly allotted in two groups: immature treatment group (n=263) and IVM treatment group (n=272). IVM of COCs was carried out in 100-μL drops of BO-IVM medium overlaying embryo tested oil in a 35-mm petri dish under 5% CO2 in a 39.0°C incubator for 24h. Cumulus of COCs of both groups were removed by treating with 0.25% trypsin, and oocytes were stored in RNALater for future use. The expression of genes was evaluated using quantitative PCR, and the relative expression of each gene was calculated using the ΔΔCt method with efficiency correction. The logarithmic transformation of fold change (log2FC) of each candidate gene in the IVM oocyte group was computed against the immature oocyte group based on the observed cycle threshold values. Appropriate standard deviations were determined based on the observed deviations among the triplicates. The expression in the IVM treatment group of previously reported upregulated genes (GDF9, HAS2, SPRY1) was higher (up to 10-fold) compared with the immature treatment group (reference group). In the present study, relatively lower expression was observed for the other candidate genes (ARHGAP22, COL18A1, GPC4) in the bovine transcripts of oocyte, which were previously also reported as being downregulated.

Abstract
BACKGROUND Obesity is a major health problem, demonstrated to double the risk of colorectal cancer. The benefits of robotic colorectal surgery in obese patients remain largely unknown. This meta-analysis evaluated the clinical and pathological outcomes of robotic colorectal surgery in obese and non-obese patients. METHODS MEDLINE, Embase, Global Health, Healthcare Management Information Consortium (HMIC) and Midwives Information and Resources Service (MIDIRS) databases were searched on 1 August 2018 with no language restriction. Meta-analysis was performed according to PRISMA guidelines. Obese patients (BMI 30 kg/m2 or above) undergoing robotic colorectal cancer resections were compared with non-obese patients. Included outcome measures were: operative outcomes (duration of surgery, conversion to laparotomy, blood loss), postoperative complications, hospital length of stay and pathological outcomes (number of retrieved lymph nodes, positive circumferential resection margins and length of distal margin in rectal surgery). RESULTS A total of 131 full-text articles were reviewed, of which 12 met the inclusion criteria and were included in the final analysis. There were 3166 non-obese and 1420 obese patients. A longer duration of surgery was documented in obese compared with non-obese patients (weighted mean difference -21·99 (95 per cent c.i. -31·52 to -12·46) min; P < 0·001). Obese patients had a higher rate of conversion to laparotomy than non-obese patients (odds ratio 1·99, 95 per cent c.i. 1·54 to 2·56; P < 0·001). Blood loss, postoperative complications, length of hospital stay and pathological outcomes were not significantly different in obese and non-obese patients. CONCLUSION Robotic surgery in obese patients results in a significantly longer duration of surgery and higher conversion rates than in non-obese patients. Further studies should focus on better stratification of the obese population with colorectal disease as candidates for robotic procedures.
