1. Human population expansion into wildlife habitats has increased interest in the behavioural ecology of human-wildlife interactions. To date, however, the socioecological factors that determine whether, when or where wild animals take risks by interacting with humans and anthropogenic factors still remains unclear.2. We adopt a comparative approach to address this gap, using social network analysis (SNA). SNA, increasingly implemented to determine human impact on wildlife ecology, can be a powerful tool to understand how animal socioecology influences the spatiotemporal distribution of human-wildlife interactions.3. For 10 groups of rhesus, long-tailed and bonnet macaques (Macaca spp.) living in anthropogenically impacted environments in Asia, we collected data on humanmacaque interactions, animal demographics, and macaque-macaque agonistic and affiliative social interactions. We constructed 'human co-interaction networks' based on associations between macaques that interacted with humans within the same time and spatial locations, and social networks based on macaque-macaque allogrooming behaviour, affiliative behaviours of short duration (agonistic support, lip-smacking, silent bare-teeth displays and non-sexual mounting) and proximity.4. Pre-network permutation tests revealed that, within all macaque groups, specific individuals jointly took risks by repeatedly, consistently co-interacting with humans within and across time and space. GLMMs revealed that macaques' tendencies to co-interact with humans was positively predicted by their tendencies to engage in short-duration affiliative interactions and tolerance of conspecifics, although the

Background and Aims:Neuraxial adjuants to local anesthetics is an effective technique of improving the quality and duration of postoperative analgesia. The safety and efficacy of drugs like dexmedetomidine and neostigmine as epidural medications have been sparsely investigated.Material and Methods:Combined spinal-epidural anesthesia was performed in 60 American Society of Anesthesiologists I and II patients who required lower limb surgeries of ≤3 h duration. The epidural drug was administered at the end of surgery with patients randomized into three groups. Group I, II and III received 6 ml of 0.25% bupivacaine alone, with 1 ug/kg of neostigmine and with 0.5 ug/kg of dexmedetomidine + 1 ug/kg of neostigmine, respectively. The patients were prescribed 50 mg tramadol intravenous as rescue analgesic. Patients were assessed for hemodynamic parameters, pain scores, duration of analgesia, rescue analgesic requirements and the incidence of side-effects over the next 10 h. Data was analyzed using SPSS® version 17.0 (Chicago, IL, USA). P < 0.05 was considered as statistically significant.Results:Patients in Group III had significantly longer mean duration of analgesia (273.5 min) compared to Group II (176.25 min) and Group I (144 min). There was increased requirement of fluids to maintain blood pressures in Group III. Neostigmine did not cause significant incidence of gastrointestinal side effects.Conclusions:Epidurally administered dexmedetomidine and neostigmine exhibit synergism in analgesic action. The incidence of drug-related side-effects was low in our study.

A 60-year-old woman sustained right femur fracture and presented to us after taking native massage therapy for 6 weeks. Radiographs showed suspected posteromedial soft tissue shadow. Further imaging confirmed a rare pseudoaneurysm of the superficial femoral artery. After vascular surgery consultation, a single-stage procedure was planned. Through medial approach to distal femur, Pseudo aneurysm was haemodynamically isolated, opened and its contents evacuated. Neck of pseudo aneurysm is located and ligated. Distal femur plating (broad DCP) was done through the same exposure. Since traumatic pseudoaneurysms are rare entities, surgeons should have a high degree of suspicion for preoperative identification. It facilitates simultaneous vascular repair and fracture fixation. It avoids two-stage incisions, two incisions, intraoperative or postoperative catastrophe, and medicolegal complications. Hence, we advocate to look out for vascular injury in distal femur fractures at a delayed presentation.
