Awareness of geriatric welfare services among rural elderly population

Background: Elderly population suffers from income loss, decreased social role and increased dependence along with physical and mental problems associated with ageing. Geriatric welfare services are aimed to address this problem related to old age. The main focus of the existing geriatric welfare services are below the poverty line elderly population. However, the benefit from these services can be obtained if elderly population have awareness about these welfare services. Main objective of the study was to study the awareness regarding geriatric welfare services among rural elderly population and its association with gender.Methods: Community based cross- sectional study was carried out at field practice area of Rural Health Training Centre, JN Medical College, AMU, Aligarh, Uttar Pradesh, India by using systematic random sampling with probability proportionate to size among 225 rural elderly individuals using pretested and predesigned questionnaire. Data analysis was done using SPSS 20. Chi square test was used. P value <0.05 was considered significant.Results: Among the geriatric welfare services 28.9% were aware of the social security schemes, 84% were aware of the special govt. facilities, 35.6% were aware of the health insurance schemes. Males had significant higher awareness of geriatric welfare services than the females.Conclusions: The study revealed that awareness of geriatric welfare services among rural elderly population was very low that needs to be addressed to improve utilization of these services.

Chronic insertional achilles tendon ruptures treated by suture anchor repair and augmentation with flexor hallucis longus tendon transfer

Background: Different surgical procedures have been used for treatment of chronic ruptures of the Achilles tendon with varying results. This study assesses the functional outcomes and complications of chronic insertional tears of Achilles tendon.Methods: 10 patients with chronic ruptures of the Achilles tendon were followed for a mean period of 10.3 months. Only ruptures at or near (within 1 cm) insertion were included. They were treated by direct repair of tendon to calcaneum by suture anchor. Flexor hallucis longus (FHL) tendon transfer fixed to calcaneal tunnel with an interference screw was used to augment the repair.Results: Outcome was assessed by AOFAS Ankle-Hindfoot (AHS) score. The mean preoperative score of 41.2 improved to 85.4 at final follow-up out of a total 100 points. We achieved excellent results in 80% and good outcome in 20% cases. No re-ruptures were noted. Conclusions: In insertional chronic ruptures of Achilles tendon, FHL transfer to calcaneum with interference screw fixation and repair of Achilles tendon with suture anchor is a reliable technique with good outcome and is recommended

Local-Partial Signal Combining Schemes for Cell-Free Large-Scale MU-MIMO Systems with Limited Fronthaul Capacity and Spatial Correlation Channels

Cell-free large-scale multi-user MIMO is a promising technology for the 5G-and-beyond mobile communication networks. Scalable signal processing is the key challenge in achieving the benefits of cell-free systems. This study examines a distributed approach for cell-free deployment with user-centric configuration and finite fronthaul capacity. Moreover, the impact of scaling the pilot length, the number of access points (APs), and the number of antennas per AP on the achievable average spectral efficiency are investigated. Using the dynamic cooperative clustering (DCC) technique and large-scale fading decoding process, we derive an approximation of the signal-tointerference-plus-noise ratio in the criteria of two local combining schemes: Local-Partial Regularized Zero Forcing (RZF) and Local Maximum Ratio (MR). The results indicate that distributed approaches in the cell-free system have the advantage of decreasing the fronthaul signaling and the computing complexity. The results also show that the Local-Partial RZF provides the highest average spectral efficiency among all the distributed combining schemes because the computational complexity of the Local-Partial RZF is independent of the UTs. Therefore, it does not grow as the number of user terminals (UTs) increases

Myoepithelial carcinoma of the male breast: a rare case report

Myoepithelial carcinoma (malignant myoepithelioma) of the breast is a rare entity and in the male breast it is even rarer. Two cases of benign myoepithelioma in the male breast have been reported so far. Here we report, probably the first case of Myoepithelial carcinoma in a male breast with clinical features mimicking locally advanced breast carcinoma, together with illustration of pathological finding, microscopic appearance and management.Keywords: Myoepithelial carcinoma; Modified radical mastectomy; Chemotherap

Solitary fibrous tumour of the submandibular region: a rare entity

Solitary fibrous tumours of the head and neck region are extremely rare. The clinical diagnosis is often difficult to establish, and this lesion may be indistinguishable from other soft tissue neoplasms. An 18-year old Chinese gentleman presented with a painless right submandibular swelling which was increasing in size for eight months. A computed tomography scan showed a well-defined solid mass measuring about 2.0 x 2.96 cm in the submandibular region. The tumour was resected and was confined within its capsule. Immunohistochemical staining was strongly positive for CD34, CD 99, and vimentin and negative for desmin, smooth muscle actin (SMA), cytokeratin, S100 and CD68. The microscopic and immunohistochemical profile were compatible with solitary fibrous tumour. Distinguishing solitary fibrous tumours from various spindle neoplasms can be difficult. In view of the resemblance, immunohistochemical staining can help differentiate solitary fibrous tumour from spindle neoplasm

Robotic exoskeleton control for lower limb rehabilitation of knee joint

Wearable devices such as exoskeletons are being opted frequently during rehabilitation processes for the post stroke recovery. Such de-vices are playing important role in the development of assistive rehabilitation robotic systems. In this paper three control strategies MPC and LQR and PID are introduced which were applied to knee joint of lower limb exoskeleton model for passive exercise. The two con-trols MPC and LQR are model based control which empowers them for stable responses. In this paper the analysis of robustness of con-trol is done under the noisy and disturbance conditions. The results showed good performance of the exoskeleton model with the applied controls in the provided condition. In the future work the applied controls will be implemented on hardware

Overview on virosomes as a novel carrier for drug delivery

As from the last eras number of the revolution in the drug delivery technologies have been seen to attain the targeted drug delivery or site specific action of the drug. The prospects of the drug delivery by using biomimetic nanoparticles such as virosomes is an motivating research &amp; development field as showing targeted action by fusion with the targeted action by fusion through target cell. It can be engaged as vehicle &amp; vaccines furthermore victory of virosomal drug delivery depends on the method used to make the encapsulated bioactive materials, characterization &amp; formulation of finished products. They are reconstituted viral envelopes that can be conveyance of different macromolecules as these are biocompatible, biodegradable, nonautoimmunogenic. Virosomes denotes such a unique system for presentation of antigen to immune system. Peptides, nucliecacid &amp; medications such as antitoxins, anticancer agents &amp;steroids can be encapsulated. This review focus on various aspects of Virosomes, such as Structure of Virosomes Component, Advantages, disadvantages, Method of preparation, Characterization, recent Patents and applications of Virosomes etc. Key words: Neurodegenerative, Nonimmunogenic, Endolysosomal, Cryoprotectants, Applications
