ABSTRACT
Abstract Birds are among the best bio-indicators, which can guide us to recognize some of the main conservation concerns in ecosystems. Anthropogenic impacts such as deforestation, habitat degradation, modification of landscapes, and decreased quality of habitats are major threats to bird diversity. The present study was designed to detect anthropogenic causative agents that act on waterbird diversity in Tarbella Dam, Indus River, Pakistan. Waterbird censuses were carried out from March 2019 to February 2020 in multiple areas around the dam. A total of 2990 waterbirds representing 63 species were recorded. We detected the highest waterbird richness and diversity at Pehure whereas the highest density was recorded at Kabbal. Human activity impacts seemed to be the main factor determining the waterbird communities as waterbirds were negatively correlated with the greatest anthropogenic impacts. Waterbirds seem to respond rapidly to human disturbance.
Resumo As aves estão entre os melhores bioindicadores, o que pode nos orientar a reconhecer algumas das principais preocupações de conservação dos ecossistemas. Impactos antrópicos como desmatamento, degradação de habitat, modificação de paisagens e diminuição da qualidade dos habitats são as principais ameaças à diversidade de aves. O presente estudo foi desenhado para detectar agentes causadores antropogênicos que atuam na diversidade de aves aquáticas na Represa de Tarbella, rio Indus, Paquistão. Censos de aves aquáticas foram realizados de março de 2019 a fevereiro de 2020 em várias áreas ao redor da barragem. Um total de 2.990 aves aquáticas representando 63 espécies foi registrado. Detectamos a maior riqueza e diversidade de aves aquáticas em Pehure, enquanto a maior densidade foi registrada em Kabbal. Os impactos da atividade humana parecem ser o principal fator determinante das comunidades de aves aquáticas, uma vez que as aves aquáticas foram negativamente correlacionadas com os maiores impactos antrópicos. As aves aquáticas parecem responder rapidamente às perturbações humanas.

Birds are very valuable indicators of species richness and endemic patterns in a specified ecosystem, which eventually help the scientist to measure the environmental degradation. The aim of present study was to know human knowledge and attitude toward urban birds in Faisalabad city, Pakistan. The study conducted in four consecutive months: November 2019 to February 2020. Population of birds was noted from eight residential towns of Faisalabad city, data were collected through questionnaire. Faisalabad has a reasonably large population of birds and present data show that, there is a significant difference between favorite bird of residential areas and institutions. The pigeon received the most likeness in bird population among residential area residents, while the myna received the least. The most popular bird in Faisalabad institutions was the sparrow, while the least popular bird was the common myna. Bird adaptation percentage of residential areas and institutional areas of Faisalabad was the highest for parrot and sparrow respectively. People in residential areas and institutions, on the other hand, adapted least to common myna. It is concluded that people of the study area like birds and offered food and high population of birds are present in study area.
Os pássaros são indicadores muito valiosos da riqueza de espécies e padrões endêmicos em um determinado ecossistema, o que acaba ajudando o cientista a medir a degradação ambiental. O objetivo do presente estudo foi conhecer o conhecimento humano e a atitude em relação às aves urbanas na cidade de Faisalabad, Paquistão. O estudo foi conduzido em quatro meses consecutivos: novembro de 2019 a fevereiro de 2020. A população de pássaros foi observada em oito cidades residenciais da cidade de Faisalabad, os dados foram coletados por meio de questionário. Faisalabad tem uma população razoavelmente grande de pássaros, e os dados atuais mostram que há uma diferença significativa entre as aves favoritas de áreas residenciais e instituições. O pombo recebeu mais semelhanças na população de pássaros entre os residentes de áreas residenciais, enquanto o myna recebeu menos. A ave mais popular nas instituições de Faisalabad era o pardal, enquanto a ave menos popular era o myna comum. A porcentagem de adaptação de pássaros em áreas residenciais e institucionais de Faisalabad foi a mais alta para papagaios e pardais, respectivamente. As pessoas em áreas residenciais e instituições, por outro lado, se adaptaram menos ao myna comum. Conclui-se que pessoas da área de estudo como pássaros e alimentos oferecidos e alta população de pássaros estão presentes na área de estudo.

BACKGROUND: An assessment of cancer incidence in population is required for prevention, early diagnosis, treatment and resource allocation. This will also guide in the formation of facilities for diagnosis, treatment, rehabilitation and follow‑up for these patients. The demographic trend of cancer will help to identify common types and etiological factors. Efforts at clinical, research and administrative levels are needed to overcome this problem. SETTINGS AND DESIGN: Present retro prospective study was conducted in regional cancer center of a tertiary care hospital. MATERIALS AND METHODS: After permission from ethics committee, a retro prospective study of 1 year duration was undertaken to study the profile of cancer patients and to compare it with other cancer registries in India. STATISTICAL ANALYSIS: Pearson’s Chi‑square test and simple linear regression were used. Statistical Package for the Social Sciences version‑16 (University of Bristol information services (www.bristol.ac.uk/is/ learning/resources) was used. RESULTS: The overall incidence of cancer in Kashmir is on the increase and common sites of cancer are esophagus and gastroesophageal (GE) junction, lung, stomach, colorectal, lymphomas, skin, laryngopharynx, acute leukemias, prostate and brain in males.In females common sites are breast, esophagus and GE junction, ovary, colorectal, stomach, lung, gallbladder, lymphomas, acute leukemias and brain. CONCLUSION: Cancers of esophagus, stomach and lungs have a high incidence both in men and women in Kashmir. Future studies on sources and types of environmental pollution and exposures in relation to these cancers may improve our understanding of risk factors held responsible for causation of these malignancies in this region. This will help in the allocation of available resources for prevention and treatment strategies.

Maxillary sinus carcinoma (MSC) is a rare disease with a variety of treatment options. The present study was undertaken to review the outcome of patients with treated MSC in order to clarify the factors related to local recurrence by analyzing CT findings. The study group comprised of 47 cases, 40 males and 7 females with a median age of 61 years (range, 40- 84 years) treated between 1988 to 1996 at the department of radiotherapy. CT was taken with a slice thickness of 5 mm and contrast material was routinely used. The mean follow-up period for the group was 45.0 months (range, 3-125 months). The treatment policy was either preoperative radiotherapy of 40Gy/16fr followed by maxillectomy or radical radiotherapy of 65Gy/26fr with partial maxillectomy during the course of radiotherapy. By using CT-simulation, wedge pair techniques were used in most patients with Cobalt or 6MV X-ray machines as treatment sources. Tumor extension was categorized into the following anatomical sites: orbital contents, other paranasal sinuses, posterior wall of the maxillary sinus, pterygoid plate/muscle, nasopharynx, infra-temporal fossa, base of the skull, anterior wall of the maxillary sinus, subcutaneous tissue, cheek mucosa, hard palate and alveolar bone. Local control was computed by using the Kaplan-Meier method and p value was measured by using Chi-squared test. The 5-year overall local control rates for all patients were 56%. The local recurrence was found in 19 of 47 patients (40.4%). Tumors extending to pterygoid plates (n=13) and pterygoid muscles (n=10) showed higher rate of local recurrences as compared to those without extensions (9/13 [69%] vs 10/34 [29%], p<0.02 and 7/10 [70%] vs 12/37 [32%], p<0.05, respectively). Extensions to nasopharynx (6/9, 66%) and base of skull (4/6, 66%) also showed higher rates of recurrence; however, those were not statistically significant. More than 80% of the relapse became manifest within 12 months of diagnosis and isolated local failure was the most common pattern. This analysis indicates that tumor extension to pterygoid plate/muscles, results in higher rates of recurrences. This may due to the difficult surgical accessibility of the tumor. During radiotherapy planning, special emphasis should be given to this sites of tumor extension to avoid possible local recurrence.
