- Objectives: To assess the feasibility of using mobile communication technology in completing a 30-day follow-up of surgical site infection (SSI). Subjects and Methods: SSIs are infections occurring up to 30 days after an operative procedure. This prospective exploratory study was conducted in a cohort of patients who were admitted and operated on in the general surgery wards of a rural hospital in India from October 2010 to June 2011. At the time of discharge, all patients were requested to follow-up in the surgical outpatient clinic at 30 days after surgery. If this was not done, a mobile phone-based surveillance was done to complete the follow-up. Results: The mean age of the 536 operated-on patients was 40 years (95% confidence interval [CI], 38-41 years). The mean duration of hospital stay was 10.7 days (95% CI, 9.9-11.6 days). Most (81%) operated-on patients were from rural areas, and 397 (75%) were male. Among the operated-on patients the ownership of mobile phones was 75% (95% CI, 73-78%). The remaining 25% of patients (n = 133) used a shared mobile phone. For 380 patients (74.5%) the follow-up was completed by mobile phones. The SSI rate at follow-up was 6.3% (n=34). In 10 patients, an SSI was detected over the mobile phone. Conclusions: Mobile communication technology is feasible to be used in rural settings to complete case follow-up for SSIs.

- Many neurotransmitters are organic ions that carry a net charge, and their release from secretory vesicles is therefore an electrodiffusion process. The selectivity of early exocytotic fusion pores is investigated by combining electrodiffusion theory, measurements of amperometric foot signals from chromaffin cells with anion substitution, and molecular dynamics simulation. The results reveal that very narrow fusion pores are cation selective, but more dilated fusion pores become anion permeable. The transition occurs around a fusion pore conductance of ∼300 pS. The cation selectivity of a narrow fusion pore accelerates the release of positively charged transmitters such as dopamine, noradrenaline, adrenaline, serotonin, and acetylcholine, while glutamate release may require a more dilated fusion pore.

- Background: Surgical site infections (SSI) are among the most commonly reported health care-associated infections; however, there is a paucity of data on SSI from India. This study aimed to determine the incidence of SSI and explore its associated factors at a teaching hospital in India. Methods: Direct and indirect surveillance methods, based on Centers for Disease Control and Prevention guidelines, were used to define SSI. Patients were followed up for 30 days postsurgery. Prescribing and resistance data were collected. Results: The SSI rate among the 720 patients investigated was 5%. Risk factors for SSI identified were as follows: severity of disease (P = .001), presence of drains (P = .020), history of previous hospitalization (P = .003), preoperative stay (P = .005), wound classification (P < .001), and surgical duration (P < .001). Independent risk factors identified included wound classification (odds ratio - 4.525; P <. 001) and surgical duration (odds ratio = 2.554; P = .015). Most patients (99%) were prescribed antibiotics. Metronidazole (24.5%), ciprofloxacin (11%), and amikacin (9%) were the most commonly prescribed antibiotics. Most commonly isolated bacteria were Staphylococcus aureus (n = 14), of which 34% were methicillin-resistant Staphylococcus aureus, and Pseudomonas aeruginosa (n = 6), which showed resistance to ceftazidime (70%), ciprofloxacin (63%), and gentamicin (57%). Conclusion: Incidence of SSI at the hospital was lower than reported in many low-and middle-income countries, although higher than reported in most high-income countries. Targeted implementation strategies to decrease incidence of preventable SSI are needed to further improve quality and safety of health care in this hospital and similar hospitals elsewhere.
