Loss of Appetite in Adult Patients: Effectiveness and Safety of an Appetite Stimulating Medication in an Open-Label, Investigator-Initiated Study in India

Loss of appetite (LOA) may have a negative impact on a patient’s well-being owing to loss of nutrition and associated conditions. The current study assessed the effects of an appetite-stimulating medication containing multivitamins, lysine, and zinc in Indian patients with a history of LOA. Using an investigator-initiated, single-center, open-label, single-arm design, we evaluated the effectiveness and safety of the appetite-stimulating medication (15 mL) in 50 male or female patients (18–55 years old) attending the outpatient department, with a confirmed diagnosis of LOA after two weeks of therapy and assessed the change in Council on Nutrition Appetite Questionnaire (CNAQ) score and safety of the medication after two weeks of treatment. CNAQ scores were presented as mean (standard deviation (SD)). The mean age of patients was 42.1 years, with the majority (66%) being males. At weeks 1 and 2, a statistically significant improvement was observed in the mean CNAQ scores of 25.48 (5.10) and 25.48 (4.29), respectively, vs. baseline (22.08 (2.76); P ≤ 0.0001 both). Majority of the patients had CNAQ appetite scores of 17–28 at baseline (94%), week 1 (66%), and week 2 (78%) of treatment. For patients with acute and chronic illness, a statistically significant improvement was observed in the mean CNAQ score at week 1 (26.75 (3.69), P = 0.0256; 25.24 (5.33), P = 0.0004) and at week 2 (26.63 (3.46), P = 0.0027; 25.26 (4.43), P ≤ 0.0001) from baseline (21.88 (3.31) and 22.12 (2.69), respectively). No serious adverse events were reported during the study. The study findings suggest that appetite-stimulating medication containing multivitamins, lysine, and zinc could be a suitable treatment option for the management of LOA with no significant safety concerns.

The nutritional environment is sufficient to select coexisting biofilm and quorum-sensing mutants of Pseudomonas aeruginosa

The evolution of bacterial populations during infections can be influenced by various factors including available nutrients, the immune system, and competing microbes, rendering it difficult to identify the specific forces that select on evolved traits. The genomes of Pseudomonas aeruginosa isolated from the airway of patients with cystic fibrosis (CF), for example, have revealed commonly mutated genes, but which phenotypes led to their prevalence is often uncertain. Here, we focus on effects of nutritional components of the CF airway on genetic adaptations by P. aeruginosa grown in either well-mixed (planktonic) or biofilm-associated conditions. After only 80 generations of experimental evolution in a simple medium with glucose, lactate, and amino acids, all planktonic populations diversified into lineages with mutated genes common to CF infections: morA , encoding a regulator of biofilm formation, or lasR , encoding a quorum sensing regulator that modulates the expression of virulence factors. Although mutated quorum sensing is often thought to be selected in vivo due to altered virulence phenotypes or social cheating, isolates with lasR mutations demonstrated increased fitness when grown alone and outcompeted the ancestral PA14 strain. Nonsynonymous SNPs in morA increased fitness in a nutrient concentration-dependent manner during planktonic growth and surprisingly also increased biofilm production. Populations propagated in biofilm conditions also acquired mutations in loci associated with chronic infections, including lasR and cyclic-di-GMP regulators roeA and wspF . These findings demonstrate that nutrient conditions and biofilm selection are sufficient to select mutants with problematic clinical phenotypes including increased biofilm and altered quorum sensing. Importance Pseudomonas aeruginosa produces dangerous chronic infections that are known for their rapid diversification and recalcitrance to treatment. We performed evolution experiments to identify adaptations selected by two specific aspects of the CF respiratory environment: nutrient levels and surface attachment. Propagation of P. aeruginosa in nutrients present within the CF airway was sufficient to drive diversification into subpopulations with identical mutations in regulators of biofilm and quorum sensing to those arising during infection. Thus, the adaptation of opportunistic pathogens to nutrients found in the host may select mutants with phenotypes that complicate treatment and clearance of infection.

Therapeutic Opportunities for Headaches and Migraines in Pediatric Populations: A Review

Headaches, migraine-like episodes, and other associated conditions are increasingly becoming the most frequent occurrence and a threat to the pediatric population in today’s world. It has become the most sought-after therapeutic opportunity in the clinical setting in a way that can help to treat, diagnose and minimize its ill effects or side effects in today’s world which has witnessed all severe forms of diseases and hopefully will witness more severe forms because of the everlasting unhealthy lifestyle and prevalent hypertension which can be maternal or paternal and can affect the newborn as well as all the pediatric age groups in today’s world. Severe forms of Headachin children or pediatric age groups can be a massive challenge for the clinician to identify, diagnose, and provide effective treatment that can be curable in most cases but can be fatal. In pediatric populations, headaches or migraines can result from underlying conditions, pathologies, or effects of maternal and paternal habits or lifestyles that need more attention than the symptom itself. The treatment spectrum ranges from pharmacological interventions to more unconventional options like acupuncture and alternative medicine. All these options are worth considering, as several studies show high efficacy and success rates with each of these conditions and etiology discussed above. In this review, the authors aim to discuss these different therapeutic options and weigh out their pros and cons, which can help in better and effective treatment to control or eliminate this disease.

Comparison of clinical and cost effectiveness of accelerated study of sterility of intravascular catheters and drains

The results of a new method for detecting the contamination of intravascular catheters and drains are presented to assess its clinical and cost-effectiveness. Catheters are one of the most widely used devices in critically ill patients. The insertion of a catheter into the central venous system is an invasive procedure that can potentially lead to life-threatening complications for the patient. Catheters are a gateway for infection as they connect the external environment to the internal parts of the human body, causing catheter-associated infections. More than 15 % of patients with an established IVC develop complications, of which the most frequent and requiring removal of the vascular catheter are infectious (5–26 %) and mechanical (up to 25 %). Risk factors for catheter-associated conditions are crucial for hospital mortality.

CECT in Pulmonary Thrombolism

Introduction: Pulmonary embolism (PE) is the third most common acute heart disease after myocardial infarction and stroke and is a major public health problem. PE is a disease that has high morbidity and mortality, yet it is challenging to obtain a diagnosis. Objective: The study aims to assess the role of MDCT-PA in the diagnosis of pulmonary embolism, and it's associated conditions in suspected cases of pulmonary embolism. Materials and Methods: The study was conducted in the department of radiology in KRISHNA INSTITUTE OF MEDICAL SCIENCES DEEMED TO BE UNIVERSITY situated in KARAD equipped with a 16 slice MDCT scanner (EMOTION) manufactured by Siemens. Results: Through the study period of one and half year and have met the inclusion criteria, a total of 90 consecutive patients who presented with suspicion of PE were referred for MDCT-PA in the department of radio-diagnosis, Krishna Hospital, Karad. A review of all the cases was done, and the results were presented in the form of tables. Conclusion: Multidetector computed tomography pulmonary angiography can be used to confidently diagnose pulmonary embolism in which it is not contraindicated. MDCT-PA is the investigation of choice because it is a rapid, non-invasive study, highly sensitive and specific.

Genomics of Pulmonary Hypertension

Background - Pulmonary hypertension (PH), defined by mean pulmonary artery pressure >20 mmHg, is a common physiologic manifestation of many diseases. Pulmonary arterial hypertension (PAH) represents a smaller subgroup of patients who have PH, and PAH causes significant cardiorespiratory morbidity and premature mortality. PH can manifest across the lifespan, with similar incidence for both pediatric- and adult-onset disease. However, pediatric-onset disease is particularly challenging because it is frequently associated with a more severe clinical course and comorbidities including lung and heart developmental anomalies. For PH Group 1/pulmonary arterial hypertension, causal genetic variants can be identified in ~13% of adults and ~43% of children. Clinical implications – Education about the option for genetic testing is strongly recommended for all pediatric and adult HPAH/IPAH patients. Both gene panel and exome/genome sequencing tests can be useful in diagnosis, but exome/genome sequencing provides a comprehensive dataset for reanalysis over time for cases without an initial diagnosis. Knowledge of genetic diagnoses can immediately impact clinical management of PH, including multimodal medical treatment, surgical intervention, transplantation decisions, and screening for associated conditions. Conclusions - There is a need for large, diverse, international consortia with ever-improving analytical pipelines to confirm previously implicated genes, identify additional genes/variants, assess penetrance, and clinically characterize each genetic subtype for natural history, prognosis and response to therapies to inform more precise clinical management.

The Association between Obesity and Chronic Conditions: Results from a Large Electronic Health Records System in Saudi Arabia

This cross-sectional study aimed to estimate the prevalence of obesity and its association with diabetes and hypertension among beneficiaries in the National Guard Health Affairs system of Saudi Arabia. We included individuals aged 17 years and older, and patients were classified as diabetic or hypertensive if they had any visit during the 4 years where the primary diagnosis was one of those conditions or they were taking diabetes or hypertension medications. The association between obesity (body mass index ≥30) and diabetes and hypertension were evaluated using a multiple logistic regression model, adjusting for age, gender, nationality, and region. A total of 616,092 individuals were included. The majority were Saudi nationals (93.1%). Approximately 68% of the population were either obese (38.9%) or overweight (29.30%). Obesity was more prevalent among Saudi nationals (39.8% vs. 26.7%, p < 0.01) and females (45.3% vs. 31.2%, p < 0.01). Obesity was independently associated with diabetes mellitus (OR = 2.24, p < 0.01) and hypertension (OR = 2.15, p < 0.01). The prevalence of obesity in the study population was alarming and more pronounced among women. Our findings call for efforts to intensify preventive measures to reduce obesity and associated conditions. Using electronic records to examine the impact of interventions to reduce obesity and chronic conditions may help monitor and improve population health.

Noninvasive Diagnosis of PLA2R-Associated Membranous Nephropathy

Background and objectivesKidney biopsy is the current gold standard to diagnose membranous nephropathy. Approximately 70%–80% of patients with primary membranous nephropathy have circulating anti-phospholipase A2 receptor antibodies. We previously demonstrated that in proteinuric patients with preserved eGFR and absence of associated conditions (e.g., autoimmunity, malignancy, infection, drugs, and paraproteinemia), a positive anti-phospholipase A2 receptor antibody test by ELISA and immunofluorescence assay confirms the diagnosis of membranous nephropathy noninvasively. These data have not been externally validated.Design, setting, participants, & measurementsThe clinical and pathologic characteristics of patients with a positive anti-phospholipase A2 receptor antibody test at the Mayo Clinic, the University Hospital Vall D’Hebron (Barcelona), and the Columbia University Medical Center (New York) were retrospectively reviewed. Biopsy findings and presence or absence of a potential associated condition were assessed.ResultsFrom a total of 276 patients with positive anti-phospholipase A2 receptor serology, previously reported patients (n=33), kidney transplant recipients (n=9), pediatric patients (n=2), and patients without kidney biopsy (n=69) were excluded. Among the 163 remaining patients, associated conditions were identified in 47 patients, and 15 patients had diabetes mellitus. All 101 patients of the final cohort had a primary diagnosis of membranous nephropathy on kidney biopsy. In the 79 patients with eGFR≥60 ml/min per 1.73 m2, none of the biopsy findings altered diagnosis or management. Among the 22 patients with decreased eGFR, additional findings included superimposed acute interstitial nephritis (n=1).ConclusionsIn patients with preserved eGFR and absence of associated conditions or diabetes, a positive anti-phospholipase A2 receptor test by either ELISA >20 RU/ml or a positive immunofluorescence assay confirms the diagnosis of membranous nephropathy, precluding the requirement for a kidney biopsy.
