Abstract
PURPOSE OF THE REVIEW Children and adolescents with cancer, along with their parents and other informal caregivers, often report using complementary and alternative medicine (CAM) during active oncology and hemato-oncology treatment. Some adopt an "alternative" approach to conventional medical care, which often entails the use of these practices without the knowledge of the treating pediatrician. In contrast, many others search for consultation provided by a pediatric integrative oncology (IO) practitioner working with the conventional medical team. IO seeks to provide evidence-based complementary medicine therapies, many of which have been shown to augment conventional supportive and palliative care, while ensuring the patient's safety. The present narrative review examines the current state of and future direction for the IO setting of care. RECENT FINDINGS A large body of published clinical research supports the effectiveness of leading Pediatric IO modalities, while addressing potential safety-related concerns. Despite the growing amount of clinical research supporting the beneficial effects and implementation of Pediatric IO models of care, there is still a need for further studies in order to establish clinical guidelines in the treatment of children and adolescents with cancer. Such IO-directed guidelines will need to address both the effectiveness and the safety of the CAM modalities being used in pediatric oncology and hemato-oncology settings, promoting a better understanding among pediatric healthcare professionals and helping them understand the indications for referral to the IO treatment service.

Abstract
BACKGROUND The proportion of childhood cancer survivors (CCS) in low/middle-income countries (LMICs) is rising. CCS often develop several physical and psycho-social long-term adverse effects, with unique healthcare needs. Primary healthcare providers (primary care physicians (PCPs)), especially in LMICs, are often not equipped to handle survivorship care. This study aimed to assess knowledge, and attitude among trainee healthcare providers concerning major issues of paediatric survivorship care. METHODS A multi-centre, cross-sectional, questionnaire-based study was conducted among nursing and medical undergraduate students, and postgraduate medical residents across three tertiary-care teaching hospitals in India-All India Institute of Medical Sciences, New Delhi; Jawaharlal Institute of Postgraduate Medical Education and Research, Puducherry; and Maulana Azad Medical College, New Delhi. A questionnaire with total of 24 questions (14 knowledge-based and 10 attitude-based) was finalised after validation by expert review and piloting. The major domains covered in the questionnaire included knowledge and attitude regarding long-term adverse effects and psychosocial, employment-related issues faced by the survivors. It was administered to the study participants electronically. The knowledge-based questions had true/false responses (scored as 0 or 1 if incorrect or correct, respectively). Attitude-based questions were scored as 5-point Likert scale. RESULTS Total 898 responses were collected (median age: 21 years, 64% (576/898) female). Among the respondents, 44% were undergraduate medical students, 42% were nursing students and 14% were postgraduate medical residents. The mean (SD) of knowledge score was 8.72 (2.04) (out of 14). On multivariable analysis, only discipline of training predicted knowledge scores regarding survivorship care. Postgraduate medical residents (9.08) as well as undergraduate medical students (8.85), had significantly higher mean knowledge scores than nursing students (8.47) (p=0.004).Two questions were answered incorrectly by the majority; children and siblings of CCS need additional genetic screening (79% incorrectly answered true), and CCS face intimacy issues in relation to normal sexual functioning (59% incorrectly answered false).Nearly half (48%) of respondents believed that their knowledge of cancer survivorship issues was inadequate. Majority of respondents (84%) suggested that oncologists should handle long-term survivorship care rather than PCPs. CONCLUSION Trainee healthcare providers in India reported inadequate knowledge regarding survivorship care. Improving awareness by incorporating survivorship in teaching curriculum is imperative to equip future PCPs to provide survivorship care across the country.

Abstract
Total hip arthroplasty (THA) is a widely practiced surgical intervention to alleviate pain and reinstate functionality in individuals afflicted with hip joint pathology. The positioning of the acetabulum assumes paramount significance in determining the efficacy of THA, exerting profound influences on biomechanical dynamics, stability, and the durability of outcomes over time. This comprehensive review meticulously evaluates contemporary methodologies for optimizing acetabular positioning in THA, encompassing advanced technologies such as computer-assisted navigation systems, patient-specific instrumentation, robotic-assisted surgical approaches, image-based planning techniques, and intraoperative fluoroscopy. Crucially, key discoveries underscore the pivotal role of precise acetabular alignment in mitigating complications such as dislocation, component wear, and impingement. Moreover, the implications for clinical practice accentuate the imperative of continuous education and training to ensure effective deployment of sophisticated methodologies. Recommendations for furthering research and enhancing practice development underscore the necessity of scrutinizing long-term prognoses, assessing cost-effectiveness, and embracing technological innovations perpetually refining THA outcomes. Collaborative endeavors among researchers, practitioners, and industry stakeholders emerge as indispensable drivers of advancement in this domain, fostering an environment conducive to elevating the standard of care for individuals undergoing THA.

Abstract
PURPOSE Physical late effects of treatment are well-documented among childhood cancer survivors in high-income countries, but whether prevalence and risk factors are comparable in low- and middle-income countries (LMICs) is unclear. We conducted a systematic review to assess physical late effect outcomes among childhood cancer survivors in LMICs. METHODS Five health sciences databases were searched from inception to November 2022 in all languages. We included observational studies conducted in LMICs that evaluated physical late effects of treatment in childhood cancer survivors. Mean or median cohort follow-up must have been ≥ 5 years from original cancer diagnosis. RESULTS Sixteen full articles and five conference abstracts were included. Studies were conducted in lower-middle (n = 12, 57%) or upper-middle income (n = 9, 43%) countries; nearly half (n = 9, 43%) were conducted in India. Five cohorts (24%) were comprised entirely of 5-year survivors. Subsequent malignant neoplasms were reported in 0-11% of survivors (n = 10 studies). Hypothyroidism and metabolic syndrome prevalence ranged from 2-49% (n = 4 studies) and 4-17% (n = 5 studies), respectively. Gonadal dysfunction ranged from 3-47% (n = 4 studies). Cardiac dysfunction ranged from 1-16% (n = 3 studies). Late effects of the musculoskeletal and urinary systems were least investigated. CONCLUSIONS Substantial knowledge gaps exist in LMIC childhood cancer survivorship. No low-income country data were found. In middle-income countries, late effects were defined and assessed variably and limited by selection bias and small sample sizes. IMPLICATIONS FOR CANCER SURVIVORS Survivors in LMICs can experience physical late effects of treatment, though additionally systematically collected data from survivor cohorts are needed to fill knowledge gaps.

Abstract
Pediatric cancer outcomes have significantly improved, and yet this success is not spread equally across cancer types or patients. Disparities data in pediatric oncology highlight needed improvements in access to care, including clinical trials and advanced testing for all patients. For cancers such as brain tumors and sarcomas, continued advancement in understanding the biology of tumor heterogeneity is an essential step toward finding new therapeutic combinations to improve outcomes. Pediatric cancer survivors need access to emerging technologies aimed at reducing or better managing toxicities from therapy. With advances in treatment and survival, pediatric oncology patients continue to need longitudinal, multidisciplinary subspecialty care. Refining the communication between pediatric oncologists, primary pediatricians, survivorship clinics, and adult primary care is key in ensuring the best lifelong care of pediatric cancer survivors. In this State-of-The-Art review, we discuss 5 major domains in pediatric oncology: reducing toxicity, cancer biology, novel therapies, detection and monitoring, and access to care, to highlight recent advances and areas for continued improvement.

Abstract
Aim In addition to the well-known toxicities of treatment, survivors of pediatric solid tumors can also develop other health-related conditions. They may either be an indirect consequence of therapy or could be unrelated to their prior history of malignancy. We aim to evaluate the nontoxicity related health conditions in survivors of pediatric solid tumors. Materials and Methods The study included a cohort of hepatoblastoma (HB), Wilm's tumor (WT), and malignant germ cell tumors (MGCT) survivors registered at pediatric surgical-oncology clinic from 1994 to 2016. Follow-up was done according to standard protocols and children were evaluated at each visit for any health-related conditions. Results Of the survivors, 318 survivors, comprising of 48, 81, and 189 survivors of HB, MGCT, and WT, respectively, were included in the analysis. We found 20.8% of patients with HB, 11.1% of patients with MGCT, and 16.4% of patients with WT to report nontoxicity-related health issues. A high prevalence of surgical conditions (3.4%), secondary malignancies (1.2%), gynecological conditions in girls (16.9%), tuberculosis (1.2%), gallstone disease (0.9%), pelvi-ureteral junction obstruction (0.9%), and neurological issues (0.9%) was noted. Two presumed survivors had died, one due to a late recurrence and the other due to a secondary malignancy. Conclusions A high prevalence of medically or surgically manageable conditions makes it imperative to keep these children under follow-up to address any health-related conditions they may subsequently develop.

Abstract
BACKGROUND The survivors of childhood cancer suffer from a number of long-term side effects. These include atherosclerosis and cardiovascular diseases (CVDs) that develop earlier in adulthood than in the rest of the population. The aim of this study was to identify prognostic factors of developing atherosclerosis before the development of symptomatic CVD. METHODS A total of 141 children that were 7-18 years old were examined; there were 116 survivors of childhood malignancies (hematopoietic and lymphoproliferative malignancies-52; neuroblastoma-22; Wilms tumor-24; other solid tumors-18) and 25 healthy controls. Anthropometric measurements, blood pressure measurements, ultrasonography of the abdomen, echocardiography, and laboratory tests were performed. RESULTS There were no significant differences in gender distribution, time from the end of the treatment, weight, BMI, prevalence of central obesity, blood pressure and resistive index of the renal arteries, lipid profile, or glucose and fibrinogen levels. Patients with solid tumors had a significantly lower height and worse renal function. Patients with hematological malignancies significantly presented the lowest shortening fraction of the left ventricle. The salusin β levels were significantly higher in the control group than among the patients. CONCLUSIONS The type and severity of side effects are closely related to the type of neoplasm and the treatment that has been undergone. Careful observation and regular follow-up are necessary.
