Impact and cost-effectiveness evaluation of nutritional supplementation and complementary interventions for tuberculosis treatment outcomes under mukti pay-for-performance model in Madhya Pradesh, India: A study protocol.

Background: A."pay-for-performance" (P4P) intervention model for improved tuberculosis (TB) outcomes, called "Mukti," has been implemented in an underdeveloped tribal area of central India. The target of this project is to improve nutritional status, quality of life (QoL), and treatment outcomes of 1000 TB patients through four interventions: food baskets, personal counseling, peer-to-peer learning and facilitation for linkage to government schemes. The current study aims to assess the success of this model by evaluating its impact and cost-effectiveness using a quasi-experimental approach. Methods: Data for impact assessment have been collected from 1000 intervention and control patients. Study outcomes such as treatment completion, sputum negativity, weight gain, and health-related QoL will be compared between matched samples. Micro costing approach will be used for assessing the cost of routine TB services provision under the national program and the incremental cost of implementing our interventions. A decision and Markov hybrid model will estimate long-term costs and health outcomes associated with the use of study interventions. Measures of health outcomes will be mortality, morbidity, and disability. Cost-effectiveness will be assessed in terms of incremental cost per quality-adjusted life-years gained and cost per unit increase in patient weight in intervention versus control groups. Results: The evidence generated from the present study in terms of impact and cost-effectiveness estimates will thus help to identify not only the effectiveness of these interventions but also the optimal mode of financing such measures. Our estimates on scale-up costs for these interventions will also help the state and the national government to consider scale-up of such interventions in the entire state or country. Discussion: The study will generate important evidence on the impact of nutritional supplementation and other complementary interventions for TB treatment outcomes delivered through P4P financing models and on the cost of scaling up these to the state and national level in India.

The underappreciated role of auriculotemporal nerve involvement in local failure following parotidectomy for cancer.

BACKGROUND: Locoregional recurrence rates following parotidectomy for cancer remain as high as 20-30%. The auriculotemporal nerve (ATN) may allow parotid cancers to spread from the facial nerve (FN) toward the skull base, causing local recurrence. METHODS: Retrospective review of 173 parotidectomies for malignancy. Preoperative and post-recurrence imaging were reviewed by a neuroradiologist for signs of tumor adjacent to the ATN. RESULTS: Clinical and imaging signs of possible ATN involvement correlated with FN weakness and sacrifice. Eight patients had pathologically confirmed tumor from the ATN or V3. Forty-four percent of local recurrences had post-recurrence imaging showing tumor along the course of the ATN. Locoregional failure along the ATN was also associated with preoperative FN weakness, intraoperative FN sacrifice, and failure to complete recommended adjuvant therapy. CONCLUSIONS: Parotid cancers may invade the FN and spread to the skull base via the ATN. If not appropriately managed, this may lead to local recurrence.

Sensitivity of Fine-Needle Aspiration and Imaging Modalities in the Diagnosis of Low-Grade Mucoepidermoid Carcinoma of the Parotid Gland.

OBJECTIVE: To determine the diagnostic accuracy of fine-needle aspiration (FNA) and imaging modalities for low-grade mucoepidermoid carcinoma (MEC) of the parotid gland. METHODS: Retrospective chart review of patients diagnosed with low-grade MEC of the parotid gland following surgical excision between January 2010 and June 2018. Imaging from patients with MEC were randomly mixed with imaging from patients with benign pathology and reviewed in a blinded fashion. Main outcome measure was sensitivity. RESULTS: A total of 24 patients were confirmed to have had low-grade MEC on final pathology, with a total of 31 FNAs performed between them. Twelve of 31 FNAs were positive for low-grade MEC, with a sensitivity of 39%. A total of 27 imaging studies were reviewed, which included 16 patients with low-grade MEC and 11 patients with benign pathology. Of these 27 imaging studies, 10 were declared indeterminate. Of the remaining 17 imaging studies, 13 were reviewed as malignant (11 true positive and 2 false positive) and 4 as benign (4 true negative). Overall magnetic resonance imaging (MRI) sensitivity for low-grade MEC was 100% (9/9) with 95% CI (0.66-1.0) when considering indeterminate results as positive for malignancy. CONCLUSION: This study reaffirms that for low-grade MEC, sensitivity of FNA is poor. MRI provides an important diagnostic tool in the evaluation of salivary gland neoplasms, due to its increased sensitivity for low-grade MEC when considering indeterminate results as positive. This provides confidence in the diagnosis of benign tumors and allows appropriate counseling of all options to the patient, including observation. Imaging and low threshold of excision should be considered despite an inflammatory or benign FNA.

Factors associated with high-risk behaviour among migrants in the state of maharashtra, India.

Studies among migrants show that they are more susceptible to HIV infection than the general population and thereby spread the epidemic from high prevalence to low prevalence areas. It is therefore critical to enhance the body of knowledge on factors associated with condom use among migrants. This study, conducted in 2009 in the State of Maharashtra, covers 4595 single in-migrants aged 15-49 years and aims at understanding the factors associated with non-use of condoms consistently. Information was collected using a Structured Interview Schedule covering demographic, socioeconomic profile, sexual history, knowledge, behaviour and stigma and discrimination indicators. Logistic regression analysis was used to understand the association between unprotected sex and various socio-demographic and environmental factors. The models were run using the Enter method. The goodness-of-fit of the model was assessed using Hosmer and Lemeshow chi-squared statistics. A significant association is observed between sex with sex workers and older migrants (>24 years), the literate, those who are mobile, unmarried, employed in the textile, quarry and construction industries, who often consume alcohol and who watch pornographic films. The factors associated with unprotected sex are age between 30 and 34 years and no literacy. Migrants who are mobile and consume alcohol show a significant association with unprotected sex. The findings suggest a need for a comprehensive HIV prevention programme including strategies to address the stressful work conditions. The prevention programmes should focus not only on skills for safer sex practices, but also on alcohol use reduction.
