There is a growing burden of lung cancer cases in India, incidence projected to increase from 63,708 cases (2015) to 81,219 cases (2025). The increasing numbers are attributed to smoking (India currently has nearly 100 million adult smokers) and environmental pollution. Most patients present with advanced disease (80-85% are incurable), causing nearly 60,000 annual deaths from lung cancer. ⋯ Developing this model over the next several years will facilitate a structured cancer screening programme for populations at the highest risk of lung cancer. In this paper, we discuss the demographics of lung cancer in India and its relation to smoking patterns. Further, we elaborate on the potential applications and challenges of bringing a smart approach to LCS in high-risk populations in India.

ReviewSalt intake, blood pressure and clinical outcomes.
Salt intake has long been known to influence blood pressure among hypertensive patients, but its effect among those without overt hypertension, as well as its effects on cardiovascular disease itself, have been disputed. This report reviews the evidence for an effect on both blood pressure and cardiovascular disease, particularly among normotensive participants, including recent data from randomized trials. ⋯ Average sodium consumption in the US population is excessively high, and well above recommended limits. Because most sodium derives from processed and restaurant foods, a reduction of sodium in these sources, as recently called for by the American Medical Association, is necessary to reduce exposure.

Obesity is a chronic metabolic disorder associated with CVD and increased morbidity and mortality. When the BMI is > or = 30 kg/m2, mortality rates from all causes, and especially CVD, are increased by 50% to 100%. There is strong evidence that weight loss in overweight and obese individuals improves risk factors for diabetes and CVD. ⋯ However, the use of physical activity as a method to lose weight seems inversely related to patients' age and BMI and directly related to the level of education. Thus, public health interventions helping these groups to become physically active remain a challenge and further emphasize the importance of the one-on-one interaction between the clinician/health care professional with the obese individual "at risk" of CVD. This notion is critical, as it has been shown that less than half of obese adults have reported being advised to lose weight under the guidance of health care professionals.

The quasi-static pressure-volume (P-V) curve of the respiratory system describes the mechanical behavior of the lungs and chest wall during inflation and deflation. To eliminate resistive and convective acceleration effects, the measurement of volume and pressure must be performed during short periods of apnea or during very slow flow. ⋯ The P-V curve has been studied in many disease states, but it has been applied most extensively to patients with acute respiratory distress syndrome, in hopes that it might allow clinicians to customize ventilator settings according to a patient's individual respiratory mechanics and thus protect the patient from ventilator-induced lung injury. However, lack of standardization of the procedure used to acquire P-V curves, difficulties in measuring absolute lung volume, lack of knowledge regarding how to use the information, and a paucity of data showing a benefit in morbidity and mortality with the use of P-V curves have tempered early enthusiasm regarding the clinical usefulness of the quasi-static P-V curve.

It is essential to minimize pain and distress during painful procedures in children. This study examined the effect of using non-immersive Virtual Reality (VR) during a needle-related procedure on reported pain or distress of children and adolescents in a paediatric oncology unit and surveyed their response to the use of VR-equipment during the procedure. ⋯ The interviews showed that non-immersive VR is a positive experience for children undergoing a minor procedure such as venous puncture or a subcutaneous venous port access.
