Debunking myths related to diabetes, sugar control & associated complications – Dr Suneel Bharadwaj

Lower HbA1c levels are associated with reduced risks of heart disease, kidney problems, nerve damage, and eye issues. Achieving this target helps improve overall quality of life and ensures better control over diabetes-related complications. However, individualized treatment goals may vary, and it’s essential to consult a healthcare professional to determine the most appropriate target for each person with diabetes.

Contrary to the myth that diabetes is solely a sugar control issue, it involves a range of complications. Prolonged high blood sugar levels can lead to serious issues such as heart disease, kidney problems, nerve damage, vision impairment, and even amputations. It affects the entire body, highlighting the importance of comprehensive diabetes management, including lifestyle changes, medication, and regular monitoring, to prevent these complications and maintain overall health.

In this video, Dr Suneel Bhardwaj, General Physician from Delhi, discusses why it is important for people with diabetes to maintain HbA1C below 7%. He dispels the myth that diabetes is merely a sugar control issue.

Pfizer gets EU nod for ulcerative colitis drug Velsipity

Pfizer’s drug to treat patients with an inflammatory bowel disease called ulcerative colitis has been approved by the European Commission, the company said on Monday.

The approval for Velsipity follows backing from the European Medicines Agency’s panel of experts in December.
The drug was approved for use in patients aged 16 or older and who did not show adequate response or were intolerant to previous treatment, Pfizer said.
The approval, applicable in all 27 countries of the European Union, is based on studies from two late-stage trials that showed the drug was effective and safe in eligible patients.
Pfizer said Velsipity will be available in each of the member countries after the national processes are complete, including applications for reimbursement for the drug.
About 2.6 million people in Europe are living with ulcerative colitis, Pfizer says.
Velsipity, which was approved in the United States in October, belongs to a class of drugs used to regulate the body’s immune response and is expected to compete with Bristol Myers Squibb’s Zeposia.
Pfizer has also sought regulatory approvals for the drug in Australia, India and the UK, among others.
Leerink Partners in October estimated the drug’s 2030 sales at $2.2 billion.

ADA releases new guideline for pharmacologic management of acute dental pain in adults, adolescents and older adults

USA: A recent article published in The Journal of the American Dental Association has reported key recommendations and good practice statements for the pharmacologic management of acute dental pain: postoperative pain after simple and surgical tooth extraction(s) in adolescents, adults, and older adults.

The document stated, that there is a beneficial net balance favoring the use of nonopioid medications compared with opioid medications. In particular, nonsteroidal anti-inflammatory drugs alone or in combination with acetaminophen likely provide superior pain relief with a more favourable safety profile than opioids.

The evidence-based recommendations were formulated by a panel convened by the American Dental Association Science and Research Institute, the University of Pennsylvania, and the University of Pittsburgh. For recommendations formulation, the panel used the Grading of Recommendations, Assessment, Development and Evaluation approach to assess the certainty of the evidence and the Grading of Recommendations, Assessment, Development and Evaluation Evidence-to-Decision Framework.

Nonopioid medications are first-line therapy for managing acute dental pain after tooth extraction(s) and the temporary management of toothache.

“The use of opioids should be reserved for clinical situations when the first-line therapy is insufficient to reduce pain or there is a contraindication of nonsteroidal anti-inflammatory drugs,” the panel stated.

“Clinicians should avoid the routine use of just-in-case prescribing of opioids and should exert extreme caution when prescribing opioids to adolescents and young adults.”

The key recommendations are described below:

  • For the management of acute postoperative dental pain in adolescents, adults, and older adults undergoing surgical tooth extraction(s), the panel recommends the postprocedural use of nonopioid analgesics as first-line therapy instead of opioid analgesics.
  • For surgical tooth extraction(s), the panel suggests initiating the postoperative pain management using a nonsteroidal anti-inflammatory drug (NSAID) alone (eg, 400 mg of ibuprofen or 440 mg of naproxen sodium) or in combination with acetaminophen (eg, 500 mg).
  • In the rare instances when postprocedural (ie, surgical tooth extraction) pain control using NSAIDs alone is inadequate, the panel suggests the addition to the previous first-line therapy prescription (ie, NSAID) of 325 mg of acetaminophen plus a combination of 325 mg of acetaminophen with an opioid (eg, 5-7.5 mg of hydrocodone or 5 mg of oxycodone) at the lowest effective dose, fewest tablets, and the shortest duration, which rarely exceeds 3 days.
  • In the rare instances when postprocedural (ie, surgical tooth extraction) pain control using NSAIDs in combination with acetaminophen (eg, 500 mg) is inadequate, the panel suggests replacing the initial first-line therapy prescription with an NSAID (eg, 400 mg of ibuprofen or 440 mg of naproxen sodium) and 325 mg of acetaminophen plus a combination of 325 mg of acetaminophen with an opioid (eg, 5-7.5 mg of hydrocodone or 5 mg of oxycodone). The opioid prescription should consider the lowest effective dose, the fewest tablets, and the shortest duration, which rarely exceeds 3 days.
  • When NSAIDs are contraindicated, the panel suggests the postprocedural use of acetaminophen alone at the full therapeutic dose (eg, 1,000 mg) or 325 mg of acetaminophen plus a combination of 325 mg of acetaminophen with an opioid (eg, 5-7.5 mg of hydrocodone or 5 mg of oxycodone) at the lowest effective dose, fewest tablets, and the shortest duration, which rarely exceeds 3 days.
  • For the management of acute postoperative dental pain in adolescents, adults, and older adults undergoing surgical tooth extraction(s), the panel suggests against adding oral, submucosal, or intramuscular corticosteroids to standard analgesic therapy (conditional, very low certainty).
  • For the management of acute postoperative dental pain in adolescents, adults, and older adults undergoing simple tooth extraction(s), the panel recommends the postprocedural use of nonopioid analgesics only and recommends against the use of opioid analgesics (conditional, low certainty).
  • For simple tooth extraction, the panel suggests initiating the pain management using an NSAID alone (eg, 400 mg of ibuprofen or 440 mg of naproxen sodium) or in combination with acetaminophen (eg, 500 mg).
  • When NSAIDs are contraindicated, the panel suggests the postprocedural use of acetaminophen alone at a full therapeutic dose (eg, 1,000 mg).
  • For the management of acute postoperative dental pain in adolescents, adults, and older adults undergoing simple and surgical tooth extraction(s), the panel suggests the postprocedural use (ie, before patient discharge) of 0.5% bupivacaine plus 1:200,000 epinephrine by block or infiltration injection or 4% articaine plus 1:100,000/1:200,000 epinephrine by infiltration injection instead of 2% lidocaine plus 1:100,000 epinephrine or 3% mepivacaine.

Good Practice Statements

  • The panel advises clinicians to counsel patients that they should expect some pain and the analgesics should make their pain manageable. The panel also recommends discussing with the patient their experience, preferences, and values regarding managing acute dental pain before prescribing.
  • The panel recommends clinicians thoroughly review the patient’s medical and social history (including illicit and recreational drug use), medications, and supplements to avoid overdose and adverse drug-drug interactions.
  • To minimize adverse effects, analgesic prescriptions should follow the principle of minimum effective dosage to achieve pain relief and avoid the routine use of delayed (ie, just-in-case prescription for breakthrough pain) opioid prescriptions.
  • If an NSAID alone or in combination with acetaminophen fails to provide adequate pain relief, and if opioids are prescribed, counsel patients regarding appropriate storage and disposal.
  • The panel recommends clinicians review the state’s prescription drug monitoring program when available to determine the prescribing of other controlled substances (eg, opioids and benzodiazepines). If the patient with acute dental pain is already receiving opioids to manage chronic pain (ie, long-term use of opioids), clinicians should prioritize the use of nonopioid analgesics (ie, first-line analgesic therapy).
  • Special care should be taken when prescribing opioids to a patient with a substance use disorder, including communication with the patient’s other healthcare providers.

Cefepime-taniborbactam superior to meropenem in treating complicated UTIs and acute pyelonephritis: NEJM

Carbapenem-resistant Enterobacterales species and multidrug-resistant Pseudomonas aeruginosa pose significant global health threats. Cefepime–taniborbactam is an investigational β-lactam and β-lactamase inhibitor combination with activity against these organisms.

A study published in The New England Journal of Medicine (NEJM) concluded that Cefepime-taniborbactam was more effective than meropenem in treating complicated urinary tract infections involving acute pyelonephritis and had a safety profile comparable to meropenem.
In this phase 3 trial, researchers assigned hospitalized adults with complicated UTIs to receive either cefepime-taniborbactam or meropenem for seven days, with the possibility of extending treatment for an additional seven days if bacteremia was present. The composite success rate on days 19-23 in the microbiologic intention-to-treat population determined the primary outcome. After confirming non-inferiority, a prespecified superiority analysis was conducted.
Key findings from the study are:
  • Six hundred sixty-one patients underwent randomization; 436 of these were included in the microITT population.
  • Patients’ mean age was 56, and nearly 38 % were 65 or older.
  • In the microITT population, UTI, acute pyelonephritis and bacteremia were detected in 57.8%, 42.2% and 13.1%, respectively.
  • 70.6 % in cefepime–taniborbactam and 58 % in the meropenem group had composite success.
  • Considering the primary outcome, Cefepime–taniborbactam was superior to meropenem with a treatment difference of 12.6 percentage points.
  • Differences in treatment response were sustained at late follow-up (when Cefepime–taniborbactam had higher composite success and clinical success.
  • In the Cefepime–taniborbactam and the meropenem groups, adverse events occurred in 35.5% and 29.0% of patients, respectively.
  • Adverse events included headache, diarrhoea, constipation, hypertension, and nausea. The frequency of SAEs was similar for both groups.
Concluding further, Cefepime-taniborbactam demonstrated superior efficacy to meropenem in managing complicated urinary tract infections with acute pyelonephritis while exhibiting a safety profile similar to that of meropenem. The study received funding from Venatorx Pharmaceuticals.

Taxane-based chemotherapy in Asian breast cancer patients tied to skin changes, hair loss: Study

South Korea: A recent study published in The Journal of Dermatology evaluated the effects of treatment regimens in Asian breast cancer (BC) patients.

The researchers revealed significantly increased odds of experiencing elevated hair loss, a higher melanin index & increased wrinkles six months post-surgery in those in the adjuvant treatment group, particularly those undergoing taxane-based chemotherapy. In the neoadjuvant treatment group, the researchers observed a reversal of hair loss in most patients after the surgery.

With the increasing number of young breast cancer patients worldwide, concerns about skin change and hair loss persist among cancer survivors.

Taxanes (paclitaxel and docetaxel) are among the most commonly prescribed anticancer drugs approved for the treatment of metastatic or locally advanced breast, gastric, non-small cell lung, prostate, head and neck, and ovarian cancers, as well as in the adjuvant setting for operable node-positive breast cancers.

The true incidence of dermatological adverse events (AEs) in patients receiving taxanes is unknown and has not been prospectively analysed, but they represent one of the major AEs associated with these agents. With an increase in the occurrence of cutaneous adverse events during treatment with novel targeted and immunological therapies when used along with taxanes, it is imperative to thoroughly understand the reactions attributable to this class. Moreover, identification and management of dermatological AEs is critical for maintaining the quality of life in cancer patients and for minimizing dose modifications of their antineoplastic regimen.

Against the above background, Joonho Shim, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea, and colleagues aimed to evaluate the skin changes and hair loss in Asian breast cancer patients and to compare them according to the treatment regimens.

Three hundred and twenty-two patients scheduled to undergo breast cancer surgery were enrolled. Skin changes and hair loss were assessed at the following two-time points: one day before surgery and six months after surgery.

Patients who had received systemic anticancer treatment prior to surgery were assigned to the neoadjuvant treatment group, while patients who were scheduled to receive systemic anticancer treatment were assigned to the adjuvant treatment group.

The key findings of the study were as follows:

  • In the adjuvant treatment group, patients with taxane-based chemotherapy had significantly higher odds of increased hair loss, an increased volume of wrinkles, and a higher melanin index.
  • In the neoadjuvant treatment group, hair loss was reversed in most patients at six months after surgery.

“Clinicians should inform breast cancer patients about the potential for hair loss and skin changes and provide supportive care to mitigate the effects on the patient’s quality of life,” the researchers concluded.

Cardio-oncology patients may have a high prevalence of sleep apnea and risk of CHF

Cardio-Oncology Patients may have high prevalence of sleep apnea and risk of CHF suggests a new study published in the American College of Cardiology.

Sleep apnea is prevalent among patients at higher risk for developing congestive heart failure (CHF) following cancer treatment and could be used as a risk factor to identify patients who would benefit from earlier treatment, according to a study being presented at ACC’s Advancing the Cardiovascular Care of the Oncology Patient course. Obstructive sleep apnea (OSA), the focus of this study, has a prevalence of 48-52% among patients with CHF in the general population. To determine the prevalence of OSA in cardio-oncology patients, researchers administered the STOP-BANG questionnaire, a well-established screening tool for sleep apnea, among 218 cardio-oncology patients and 296 general cardiology patients. Data were collected on traditional risk factors, STOP-BANG scores and history of sleep for both groups. Baseline echocardiogram left ventricular ejection fraction (LVEF)and Global Longitudinal LV Strain (GLS) results were measured for the cardio-oncology population. Other research has shown that LVEF and GLS can predict early cancer-therapy-related cardiomyopathy, and OSA is also linked to LV dysfunction, CHF and abnormal LV-GLS. “Echocardiogram has evolved to be a useful tool to detect and therefore treat cardiomyopathy early in patients with sleep apnea and in the cardio-oncology population, so we also wanted to see if there are shared echo markers that identify patients who are at greater risk as they start their journey to treat their cancer,” says Mini K. Das, MD, FACC, medical director of the cardio-oncology program at Baptist Health in Louisville, KY, and the study’s primary author. Results showed that the incidence of sleep apnea was 39% in the cardio-oncology group and 54% in the general cardiology group. The researchers note that individuals with untreated sleep apnea and those at higher risk for sleep apnea have abnormal baseline LV strain, a common echo parameter linked to adverse cardiovascular events. “Identifying these individuals may allow early intervention in a risk factor clearly associated with HF now recognized to affect cancer therapy and survivorship,” Das says. Notably, the study showed that the prevalence of sleep apnea in the cardio-oncology group was equal to or greater than other traditional risk factors used in current risk factor profile algorithms and that LV GLS was more abnormal in patients with untreated sleep apnea or a high STOP-BANG score. “Sleep apnea should be incorporated into current risk algorithms and a larger study is needed to evaluate the impact of sleep apnea in this high-risk population. We feel that sleep apnea assessment must be a part of routine risk assessment for patients undergoing cancer therapeutics,” says Das. Advancing the Cardiovascular Care of the Oncology Patient, being held Feb. 9 to 11, is an interdisciplinary course that highlights emerging strategies and best practices for managing the heart health of cancer patients.

Study identifies association of haemoglobin levels with BMD and fracture risk in patients with type 2 diabetes

China: A recent study published in Frontiers in Endocrinology has identified an association between haemoglobin (Hb) levels and bone mineral density (BMD) and 10-year fracture risk among a population with type 2 diabetes (T2D). 

The study provided a new perspective on the association of Hb level and BMDs with fracture risk.

The study further revealed that relatively high haemoglobin levels protected bone quality in an older male population with type 2 diabetes, but lower Hb levels were associated with lower BMD and high future fracture risk in a non-older female population with T2D.

“The bone-protective effect of haemoglobin is influenced by sex and age and persists only in older men and non-older women with T2DM,” the researchers wrote.

Osteoporosis is a disease characterized by weaker, more fragile bones, and lowered bone density—patients with diabetes experience an increased osteoporosis risk, particularly in the Asian population. Anaemia incidence is also higher in T2D patients compared with the general population. Previous research has identified an association between anaemia and osteoporosis in people with T2D, irrespective of sex and without stratification by age.

Against the above background, Ren-xuan Li, Shandong University, Jinan, Shandong, China, and colleagues aimed to investigate the associations between haemoglobin Levels and BMD and fracture risk in type 2 diabetes populations of different ages.

For this purpose, they conducted a cross-sectional study comprising 641 patients with T2DM (57.9% males). BMD of the femoral neck (FN), lumbar spine (LS), and total hip (TH) were measured using dual-energy X-ray absorptiometry.

The 10-year probability of fracture was evaluated using a fracture risk assessment tool (FRAX). Haemoglobin and other biochemical indices were measured in a certified laboratory at a hospital. Generalized additive models (GAMs) were used to identify the associations between Hb and BMD and fracture risk.

The study led to the following findings:

  • Patients with osteoporosis have lower haemoglobin levels than the non-osteoporotic population and lower FN BMD in patients with anaemia than in the non-anaemic population.
  • In patients with T2DM, there was sex- and age-related variability in the correlation between HGB levels and BMDs and fracture risk.
  • In older men, haemoglobin level was an independent determinant of BMD and was positively correlated with FN and TH BMD.
  • In non-older women, haemoglobin level was an independent determinant of BMD and fracture risk, positively associated with BMDs, and negatively associated with the 10-year probability of fracture risk.
  • GAMs revealed a positive linear association between haemoglobin level and BMDs in non-older female patients but not in older male patients.

“The present study showed for the first time that lower haemoglobin levels are associated with lower FN and TH BMD in older male T2D population and that lower Hb levels are associated with lower BMD and higher future fracture risk in a non-older female T2D population,” the researchers wrote. “Relatively low HGB levels in this population may be an independent risk factor for osteoporosis and osteoporotic fractures.”

“There is a need for further studies to confirm these results and investigate the potential mechanisms,” they concluded.
