Indian Academy of Pediatrics Consensus Guidelines on Preconception Care.

JUSTIFICATION: The preconception period is the earliest window of opportunity to ensure optimal human development.  Pregnancy and childbirth outcomes can be improved by interventions offered to support the health and well-being of women and couples prior to conception. Thus, preconception care is essential in preparing for the first thousand days of life. Adolescence, the stage of life that typically comes before the preconception stage, is characterized by various high-risk behaviors like substance abuse, sexual experimentation, injuries, obesity, and mental health issues which can adversely affect their health in adult life. Thus, a Consensus Guideline for pediatricians on providing preconception care to adolescents and young adults can go a long way in making the generations to come, healthier and more productive. OBJECTIVES: The purpose of these recommendations is to formulate an evidence-based Consensus Statement that can serve as a guidance for medical professionals to provide preconception care for young adults and adolescents. INTENDED USERS: All obstetric, pediatric, and adolescent health care providers. TARGET POPULATION: Adolescents and young adults. PROCESS: A large proportion of adolescents seek care from pediatricians and there is a lack of Consensus Guidelines on preconception care. Therefore, the Indian Academy of Pediatrics called an online National Consultative Meeting on April 03, 2023, under the chairmanship of Dr MKC Nair and the National Convenor Dr Himabindu Singh. A group of pediatricians with wide experience and expertise in adolescent health care were assigned the task of formulating evidence-based guidelines on preconception care. The group conducted a comprehensive review of existing evidence by searching resources including PubMed and Cochrane databases. Subsequently, a physical meeting was held at Amritsar on October 07, 2023 during which the consensus was reached through discussions and voting. The level of evidence (LoE) of each recommendation was graded as per the Oxford Centre for Evidence-Based Medicine (OCEBM) 2011. RECOMMENDATIONS: Every woman planning a pregnancy needs to attain and maintain a eumetabolic state. Prospective couples need to be counselled on the importance of a healthy lifestyle including a nutritious diet, avoidance of substance abuse, and timely screening for genetic disorders. Screening for and management of sexually transmitted diseases in males and females, appropriate vaccination and addressing mental health concerns are also recommended.

A Randomized Controlled Pilot Study of the Food Order Behavioral Intervention in Prediabetes.

(1) Background: Prior research in individuals with overweight/obesity and prediabetes or type 2 diabetes has shown that the ingestion of protein-rich food and non-starchy vegetables before concentrated carbohydrates (a carbohydrate-last food order) led to lower postprandial glucose excursions over 180 min, compared to eating the same foods in the reverse order. To expand upon this research, we sought to examine the feasibility and impact of carbohydrate-last food order behavioral intervention on glucose tolerance (GT), HbA1c, weight, and nutrient intake in adults with prediabetes in the real world over a 16-week span. (2) Methods: A total of 45 adults with overweight/obesity and prediabetes were randomized to receive 4-monthly standard nutritional counseling (C) or standard nutritional counseling plus carbohydrate-last food order counseling (FO) sessions (NCT# NCT03896360). (3) Results: The FO group decreased in body weight (-3.6 ± 5.7 lbs, p = 0.017), and trended toward lower HbA1c (-0.1 ± 0.2, p = 0.054). The C group weight trended lower (-2.6 ± 6.8 lbs, p = 0.102) without altering HbA1c (-0.03 ± 0.3, p = 0.605). GT was unchanged in both groups after 16 weeks. Changes in weight, HbA1c, and GT were similar between groups. Sensitivity analysis of pre-COVID participants showed significant weight loss in the FO group (-5.9 ± 5.3 lbs, p = 0.003) but not in C group (-1.0 ± 6.8 lbs, p = 0.608). After 16 weeks, the C group significantly reduced its daily intake of calories, fat, protein, and grains whereas the FO group increased its daily intake of vegetables and protein. There were 17 (94%) FO participants that reported high intervention adherence and 13 (72%) reported it was easy to eat protein/vegetables before carbohydrates. (4) Conclusions: A carbohydrate-last food order is a feasible behavioral strategy in individuals with prediabetes that improves diet quality, notably increasing protein and vegetable intake.

The feasibility, acceptability, and usability of telehealth visits.

Background: Telemedicine is now common practice for many fields of medicine, but questions remain as to whether telemedicine will continue as an important patient care modality once COVID-19 becomes endemic. We explored provider and patients' perspectives on telemedicine implementation. Methods: Physicians from three specialties within the Department of Medicine of a single institution were electronically surveyed regarding their perceptions of satisfaction, benefits, and challenges of video visits, as well as the quality of interactions with patients. Patients were surveyed via telephone by the Survey Research Group at Cornell about participation in video visits, challenges encountered, perceived benefits, preferences for care, and overall satisfaction. Results: Providers reported an overwhelmingly positive experience with video visits, with the vast majority agreeing that they were comfortable with the modality (98%) and that it was easy to interact with patients (92%). Most providers (72%) wanted to have more telemedicine encounters in the future. Key factors interfering with successful telemedicine encounters were technical challenges and insufficient technical support. Overall, patients also perceived video visits very positively regarding ease of communication and care received and had few privacy concerns. Some (10%-15%) patients expressed interest in receiving more technical support and training. There was a gradient of satisfaction with telemedicine across specialties with patients receiving weight management reporting more favorable responses while patients with lymphoma expressed more mixed responses. Conclusion: Both providers and patients found telemedicine to be an acceptable and useful modality to provide or receive medical care. The principal barrier to successful encounters was technical challenges.

Five-year Weight Loss Maintenance With Obesity Pharmacotherapy.

CONTEXT: Long-term treatment of obesity with lifestyle changes alone is unsustainable for most individuals because of several factors including adherence and metabolic adaptation. Medical management of obesity has proven efficacy for up to 3 years in randomized controlled trials. However, there is a dearth of information regarding real-world outcomes beyond 3 years. OBJECTIVE: This work aimed to assess long-term weight loss outcomes over a 2.5- to 5.5-year period with US Food and Drug Administration (FDA)-approved and off-label antiobesity medications (AOMs). METHODS: A cohort of 428 patients with overweight or obesity were treated with AOMs at an academic weight management center with an initial visit between April 1, 2014, and April 1, 2016. Intervention included FDA-approved and off-label AOMs. The primary outcome was percentage weight loss from initial to final visit. Key secondary outcomes included weight reduction targets as well as demographic and clinical predictors of long-term weight loss. RESULTS: The average weight loss was 10.4% at a mean follow-up duration of 4.4 years. The proportions of patients who met the weight reduction targets of 5% or greater, 10% or greater, 15% or greater, and 20% or greater were 70.8%, 48.1%, 29.9%, and 17.1%, respectively. On average, 51% of maximum weight loss was regained, while 40.2% of patients maintained their weight loss. In a multivariable regression analysis, a higher number of clinic visits was associated with more weight loss. Metformin, topiramate, and bupropion were associated with increased odds of maintaining 10% or greater weight loss. CONCLUSION: Clinically significant long-term weight loss of 10% or more beyond 4 years is achievable in clinical practice settings with obesity pharmacotherapy.

Impact of Adjunctive Pharmacotherapy With Intragastric Balloons for the Treatment of Obesity.

BACKGROUND: We conducted this study to compare the weight loss outcome of intragastric balloons (IGBs) in conjunction with pharmacotherapy vs IGB and intensive lifestyle changes alone. METHODS: This was a multicenter, non-randomized, retrospective study involving 4 academic hospitals. Patients underwent IGB placement with or without concomitant anti-obesity pharmacotherapy. The primary outcome was percent total weight loss (TBWL) after IGB placement at 6 and 12 months. RESULTS: This study included 102 patients, with 23 patients (mean age 46.6 years, 82.6% female) treated with IGB/pharmacotherapy and 79 patients (mean age 46.0 years, 88.6% female) treated with IGB/lifestyle modifications. Patients had a 100% follow-up rate at 6 and 12 months. At 6 months following IGB placement, both groups achieved a similar %TBWL. At 12 months, %TBWL was greater in the IGB/pharmacotherapy group (12.6% ± 1.2 vs 9.7% ± 0.7, P = .04). 65.2% of patients achieved ≥10% TBWL at 12 months in the IGB/pharmacotherapy group, compared to 38.0% in the IGB/lifestyle group (P < .05). The proportion of patients that achieved ≥15% weight loss at 12 months was also significantly different between the IGB/pharmacotherapy and IGB/lifestyle groups (30.4% vs 20.3%, P < .05). DISCUSSION: IGB with concomitant use of pharmacotherapy did not improve weight loss while the IGB was in place compared to IGB and lifestyle changes. However, patients receiving IGB with pharmacotherapy did have greater weight loss and diminished weight regain after balloon removal compared to those receiving just IGB and lifestyle changes.

Medical weight management protects against weight gain during the COVID-19 pandemic.

Background: American adults have gained weight during the COVID-19 pandemic. Little is known about how patients who are medically managed for overweight and obesity, including patients who are prescribed antiobesity pharmacotherapy, have fared. Objective: To assess the COVID-19 pandemic's effect on weight, food choices, and health behaviors in patients receiving medical treatment for overweight or obesity. Methods: Adult patients treated at an urban academic weight management center between 1 May 2019 and 1 May 2020 were electronically surveyed between 23 February and 23 March 2021. The survey assessed changes in weight, eating, behaviors, and the use of antiobesity medications (AOMs) following issuance of social distancing/stay-at-home policies in March 2020. Results: In 970 respondents, median percent weight change for those taking AOMs was -0.459% [interquartile range -5.46%-(+3.73%)] compared to +2.33% [IQR -1.92%-(+6.52%)] for those not taking AOMs (p < 0.001). More participants achieved ≥5% weight loss if they were taking AOMs compared to those who were not (26.7% vs. 15.8%, p = 0.004), and weight gain ≥5% was also lower in those taking AOMs (19.8% vs. 30.3%, p = 0.004). Patients with pre-pandemic BMI ≥30 kg/m2 taking AOMs experienced the greatest weight reduction, and there was greater weight loss associated with increased physical activity. Conclusions and Relevance: Medical weight management protected against weight gain during this period of the COVID-19 pandemic. Increased physical activity, decreased alcohol intake, and use of AOMs were factors that contributed to this protective effect.

Tirzepatide: Does the Evidence to Date Show Potential for the Treatment of Early Stage Type 2 Diabetes?

Tirzepatide is a novel "twincretin" with glucagon-like peptide 1 and glucose-dependent insulinotropic polypeptide receptor agonist activity, which was recently approved by the Food and Drug Administration for the treatment of type 2 diabetes mellitus. In this review, we discuss preclinical and mechanistic human studies, which demonstrate improvements in insulin sensitivity and beta-cell function with the use of tirzepatide, as compared to placebo and glucagon-like peptide 1 receptor agonists. We then discuss SURPASS trials 1-5, which evaluated the safety and efficacy of tirzepatide for type 2 diabetes mellitus as either monotherapy or combination therapy with other antidiabetic agents. The magnitude of tirzepatide's effects and the efficacy relative to other anti-diabetes medications on weight, glycemic control, and beta-cell function may prove beneficial for the treatment of early type 2 diabetes mellitus. Further studies, including data on cardiovascular outcomes and long-term safety, will continue to elucidate the role of tirzepatide in the treatment algorithm of type 2 diabetes mellitus.

Management of Weight Regain Following Bariatric Surgery: Behavioral Intervention and Pharmacotherapy.

INTRODUCTION: Bariatric surgery is the most effective intervention currently available for significant and durable weight loss, but weight regain after surgery is not uncommon. This paper focuses on updates in behavioral interventions and pharmacotherapy to combat weight regain after bariatric surgery. AREAS COVERED: This paper critically reviews both prospective and retrospective studies assessing pharmacotherapy in post-bariatric surgical patients published within the past 5 years. It also evaluates updates in behavioral therapies and delivery of the therapies in this patient population. EXPERT OPINION: Weight regain after bariatric surgery is common. Patients who experience weight regain should be evaluated and treated by a multidisciplinary team. Antiobesity pharmacotherapy should be considered for those who qualify as an adjunct to lifestyle modifications, along with behavioral interventions such as cognitive behavioral therapy.

Literature review on antiobesity medication use for metabolic and bariatric surgery patients from the American Society for Metabolic and Bariatric Surgery Clinical Issues Committee.

The following literature search is in response to inquiries made to the American Society for Metabolic and Bariatric Surgery (ASMBS) regarding antiobesity medication (AOM) use in patients who are having or have already had metabolic and bariatric surgery (MBS). These recommendations are based on current clinical knowledge, expert opinion, and published peer-reviewed scientific evidence available at this time. This paper is not intended to establish a local, regional, or national standard of care. The paper will be revised in the future as additional evidence becomes available.

Long-term weight loss maintenance with obesity pharmacotherapy: A retrospective cohort study.

Objective: To determine the association of anti-obesity medications (AOMs) with weight loss maintenance over 2 years. Methods: This is a retrospective observational cohort study of adults treated for obesity between 1 April 2014 and 1 April 2016 at a tertiary academic weight management center and who completed 2 years of follow-up. Main outcome measures were mean percent weight loss, percent of individuals who achieved clinically significant long-term weight loss (≥5% weight loss over 2 years), and long-term weight loss maintenance (achievement of ≥5% weight loss at 1 year and maintenance of the ≥5% reduction for the second year). Results: Of the 1566 new patients, 421 completed 1- and 2-year follow-up appointments. Patients were mostly female and on average 51 years old; they weighed 100.1 kg and had a BMI of 35.8 kg/m2 at initial visit. Mean weight losses at 1 and 2 years were 10.1% and 10.2%, respectively. The proportion of patients who experienced ≥5% weight loss was 75.5% at 1 year and 72.9% at 2 years. Long-term weight loss maintenance was achieved by 65.3% of patients. Almost all (96.2%) were on ≥1 AOM at 2 years, with metformin, phentermine, and topiramate among the most prescribed. AOM usage and older age demonstrated trends toward predicting weight loss maintenance over 2 years. Conclusions: Long-term weight loss maintenance was observed among adults with medically managed obesity who completed 2 years of follow-up.

Weight Loss Outcomes With Telemedicine During COVID-19.

Background: Amidst the COVID-19 pandemic, telemedicine was rapidly implemented to maintain patient care during quarantine. However, there is little data on how this transition may have impacted weight loss outcomes and interventions among patients with overweight or obesity. Methods: This was a retrospective observational study of adults who established care for medically managed obesity at the Weill Cornell Comprehensive Weight Control Center during September-November 2019 and May-July 2020 and who completed 6 months of follow-up. Weight loss outcomes and weight management interventions were explored and stratified by patient-provider interaction: in-person visits only, in-person and video visits, and video visits only. Results: Of 499 charts eligible for review, 245 (49%) returned for their 6-month follow-up visit and were included for analysis. Of 245 patients, 69 had in-person visits only ("in-person"), 85 started in-person and later switched to video visits ("hybrid"), and 91 had video visits only ("video"). All cohorts were predominantly white and female. Median ages were 56, 49, and 49 years; baseline median weights were 98.9, 96.8, and 93.0 kg; and baseline median BMIs were 35.3, 34.4, and 34.0 kg/m2 for in-person, hybrid, and video cohorts, respectively. The median percent weight changes over 6 months were not significantly different among cohorts: -4.3% [-8.5, -1.5] in the in-person cohort, -5.6% [-8.7, -2.2] in the hybrid group, and -5.8% [-9.7, -2.4] in the video cohort. The percent of patients who achieved ≥5% weight loss were also similar: 46.4%, 55.3%, and 59.3%, respectively. The median number of visits in the video cohort was more than in the in-person or hybrid groups (5 vs. 4). Median number of anti-obesity medications (AOMs) prescribed was similar among groups. The most common AOMs were metformin (all cohorts) followed by semaglutide 1.0 mg (in-person and video) or topiramate (hybrid). Conclusion: Patients on anti-obesity medications who were followed for 6 months via video or video plus in-person visits (hybrid) experienced clinically significant weight loss. Median number of AOMs were similar among groups, and the most common AOMs were metformin, semaglutide 1.0 mg, and topiramate. More investigation is required to compare telemedicine models with in-person care.

Hyperglycemia in acute COVID-19 is characterized by insulin resistance and adipose tissue infectivity by SARS-CoV-2.

Individuals infected with SARS-CoV-2 who also display hyperglycemia suffer from longer hospital stays, higher risk of developing acute respiratory distress syndrome (ARDS), and increased mortality. Nevertheless, the pathophysiological mechanism of hyperglycemia in COVID-19 remains poorly characterized. Here, we show that hyperglycemia is similarly prevalent among patients with ARDS independent of COVID-19 status. Yet among patients with ARDS and COVID-19, insulin resistance is the prevalent cause of hyperglycemia, independent of glucocorticoid treatment, which is unlike patients with ARDS but without COVID-19, where pancreatic beta cell failure predominates. A screen of glucoregulatory hormones revealed lower levels of adiponectin in patients with COVID-19. Hamsters infected with SARS-CoV-2 demonstrated a strong antiviral gene expression program in the adipose tissue and diminished expression of adiponectin. Moreover, we show that SARS-CoV-2 can infect adipocytes. Together these data suggest that SARS-CoV-2 may trigger adipose tissue dysfunction to drive insulin resistance and adverse outcomes in acute COVID-19.

Preadmission predictors of severe COVID-19 in patients with diabetes mellitus.

OBJECTIVE: To explore predictors of severe COVID-19 disease in patients with diabetes hospitalized for COVID-19. METHODS: This is a retrospective observational study of adults with diabetes admitted for COVID-19. Bivariate tests and multivariable Cox regression were used to identify risk factors for severe COVID-19, defined as a composite endpoint of intensive care unit admission/intubation or in-hospital death. RESULTS: In 1134 patients with diabetes admitted for COVID-19, more severe disease was associated with older age (HR 1.02, p<0.001), male sex (HR 1.28, p=0.017), Asian race (HR 1.34, p=0.029 [reference: white]), and greater obesity (moderate obesity HR 1.59, p=0.015; severe obesity HR 2.07, p=0.002 [reference: normal body mass index]). Outpatient diabetes medications were not associated with outcomes. CONCLUSIONS: Age, male sex, Asian race, and obesity were associated with increased risk of severe COVID-19 disease in adults with type 2 diabetes hospitalized for COVID-19. SUMMARY: In patients with type 2 diabetes hospitalized for COVID-19 disease, we observed that age, male sex, Asian race, and obesity predicted severe COVID-19 outcomes of intensive care unit admission, intubation, or in-hospital death. The risk conferred by obesity increased with worsening obesity. Outpatient diabetes medications were not observed to be significant predictors of study outcomes.

Combined medical strategies for the management of type 2 diabetes mellitus and obesity in adults.

INTRODUCTION: Given the relationship between the pathogenesis of obesity and type 2 diabetes mellitus (T2DM) as well as their significant health consequences, treatment strategies that can induce weight loss while achieving glycemic control are needed. Novel weight-reducing anti-diabetic agents along with anti-obesity medications (AOMs) can help medical providers address both conditions simultaneously and effectively. AREAS COVERED: This review summarizes and compares weight loss efficacy and glycemic control of weight-reducing anti-diabetic medications, AOMs and emerging pharmacologic agents that help treat both obesity and T2DM. EXPERT OPINION: Management of obesity and T2DM can be challenging to achieve and sustain in the presence of obesogenic anti-diabetic agents. Utilizing weight-reducing anti-diabetic agents, AOMs, and endobariatric or surgical procedures, either separately or in combination, can help achieve better clinical outcomes in patients with obesity and T2DM. Some agents in development, such as tirzepatide and bimagrumab, are promising pharmacotherapy options that may change the standards of care for cardiometabolic disease management.

Hyperglycemia in Acute COVID-19 is Characterized by Adipose Tissue Dysfunction and Insulin Resistance.

COVID-19 has proven to be a metabolic disease resulting in adverse outcomes in individuals with diabetes or obesity. Patients infected with SARS-CoV-2 and hyperglycemia suffer from longer hospital stays, higher risk of developing acute respiratory distress syndrome (ARDS), and increased mortality compared to those who do not develop hyperglycemia. Nevertheless, the pathophysiological mechanism(s) of hyperglycemia in COVID-19 remains poorly characterized. Here we show that insulin resistance rather than pancreatic beta cell failure is the prevalent cause of hyperglycemia in COVID-19 patients with ARDS, independent of glucocorticoid treatment. A screen of protein hormones that regulate glucose homeostasis reveals that the insulin sensitizing adipokine adiponectin is reduced in hyperglycemic COVID-19 patients. Hamsters infected with SARS-CoV-2 also have diminished expression of adiponectin. Together these data suggest that adipose tissue dysfunction may be a driver of insulin resistance and adverse outcomes in acute COVID-19.

The Independent Risk of Obesity and Diabetes and Their Interaction in COVID-19: A Retrospective Cohort Study.

OBJECTIVE: This study aimed to assess whether diabetes mellitus (DM) or obesity is an independent risk factor for severe coronavirus disease 2019 (COVID-19) outcomes and to explore whether the risk conferred by one condition is modified by the other. METHODS: This retrospective cohort study of inpatient adults with COVID-19 used multivariable Cox regression to determine the independent effects of DM and obesity on the composite outcome of intubation, intensive care unit admission, or in-hospital mortality. Effect modification between DM and obesity was assessed with a statistical interaction term and an exploration of stratum-specific effects. RESULTS: Out of 3,533 patients, a total of 1,134 (32%) had DM, 1,256 (36%) had obesity, and 430 (12%) had both. DM and obesity were independently associated with the composite outcome (hazard ratio [HR] 1.14 [95% CI: 1.01-1.30] and HR 1.22 [95% CI: 1.05-1.43], respectively). A statistical trend for potential interaction between DM and obesity was observed (P = 0.20). Stratified analyses showed potential increased risk with obesity compared with normal weight among patients with DM (HR 1.34 [95% CI: 1.04-1.74]) and patients without DM (HR 1.18 [95% CI: 0.96-1.43]). CONCLUSIONS: DM and obesity are independent risk factors associated with COVID-19 severity. Stratified analyses suggest that obesity may confer greater risk to patients with DM compared with patients without DM, and this relationship requires further exploration.

An update on pharmacotherapeutic strategies for obesity.

INTRODUCTION: The field of obesity medicine has evolved over the past several years. With greater understanding of its pathophysiology, obesity is regarded more as a chronic disease than a lifestyle choice. However, it is difficult to treat with lifestyle modifications alone due to the complexity of energy dysregulation. The availability of anti-obesity medications (AOMs) provides practitioners with more effective and sustainable ways to treat obesity. AREAS COVERED: This review briefly summarizes the weight loss efficacy of AOMs currently approved for long-term use and expands on their therapeutic potential beyond weight loss with particular focus on obesity-related comorbidities. Possible future AOMs with promising phase II or III data are also covered. EXPERT OPINION: The future of obesity medicine is in recognizing obesity as a disease and approaching treatment similarly to other chronic diseases. Lifestyle interventions alone are rarely sufficient in the treatment of chronic diseases, and pharmacotherapy often plays a necessary role in changing the course of disease. Current AOMs have proven efficacy in weight management and emerging therapeutic uses in obesity-related comorbidities, such as non-alcoholic fatty liver disease, obstructive sleep apnea, and polycystic ovarian syndrome. The development of new AOMs will further empower providers to deliver effective obesity management.

Use of Weight Loss Medications in Patients after Bariatric Surgery.

PURPOSE OF REVIEW: Weight regain after bariatric surgery is unfortunately a common occurrence. In this article, we have reviewed the data addressing this clinical problem focusing on pharmacological management of weight regain. RECENT FINDINGS: Data from several small, non-randomized, retrospective, and prospective studies provide evidence that a number of pharmacological options, both FDA approved and off-label, are effective in mitigating and managing weight regain after bariatric surgery. There is a suggestion that the optimal time to initiate weight loss medications may be at the time of weight plateau, rather than after weight regain. Adjuvant pharmacotherapy can help treat weight regain after bariatric surgery. Future studies should investigate the optimal timing for starting weight loss medications, as well as the best medication or combinations of medicines, for managing postoperative weight regain in different patient groups, including those who have undergone different types of bariatric surgeries.
