Psychotherapy: A Way Forward to Improve the Quality of Life in Otalgia Patients

引用

International Journal of Clinical Medicine 2019年第7期10卷 386-393页

作者： Salman Baig sara sadiq Department of Otolaryngology Bahria International Hospital Karachi Pakistan Department of Physiology CMH Institute of Medical Sciences Bahawalpur Pakistan

Introduction: Otalgia is not only an indicator of impact of disease but also impairs the daily activities and personal behaviors as is unpleasant and disturbing for the patient. It leads to decrease in functional status up to the complete disability. Nowadays the main focus of physician is to eradicate the disease or the symptoms, leaving behind the humanistic element. In diseased state, the most important point is to assess and improve the quality of life by using multidisciplinary approach. Objective: The objective is to assess the quality of life in patients having otalgia, due to any cause. Methodology: A descriptive cross sectional study was conducted by using modified form of WHOQOL-100 and COQOL. Data was accepted, if CFI was greater than 0.9. Qualitative data were presented as frequency and percentages and quantitative data as mean with standard deviation. ANOVA was used to assess the variations among groups. Change in behavior was assessed by using the Likert scale for each domain of WHOQOL and COQOL by a ten-point scale. Results: Majority of participants about 60.2% were male and were from the age group of 16 - 30 years. Most of the sample population were from lower socioeconomic class. Looking over the WHOQOL-100, higher score represented the higher quality of life. Variation among different socioeconomic status was non-significant for positive attitudes but was highly significant (p = 0.0020) for negative attitudes. Analyzing the COQOL scoring system, higher score reported the worse symptoms. The patient with high COQOL showed strong correlation with poor WHOQOL-100 score that was p value Conclusion: The current study highlights the need of multidisciplinary approach for the better management and improving the quality of life in patients with otalgia.

Interpreting siliciclastic sedimentation in the upper Paleozoic Mulargia-Escalaplano Basin(Sardinia, Italy):influence of tectonics on provenance

引用

Journal of Palaeogeography 2024年第1期13卷 18-34页

作者： Luca G.Costamagna sara Criniti Dipartimento di Scienze Chimiche e Geologiche Citadella UniversitariaBlocco A09042 Monserrato CAItaly Dipartimento di Ingegneria dell'Ambiente Universita della Calabria87036 Arcavacata di Rende CSItaly

Late to post-Variscan molassic basins of Late Pennsylvanian-Permian age are exposed in Sardinia(Italy). Here, the compositional and stratigraphic evolution of the Mulargia-Escalaplano sedimentary basin(central Sardinia) has been investigated to highlight how the tectono-magmatic processes have influenced the sedimentation. Ruditic and arenitic samples were collected along well-characterized stratigraphic sections to provide a new insight into the impact of the tectono-magmatic processes on siliciclastic sedimentation. As a result, the conglomerates are mainly clast-supported, petromictic, and thus immature, with no defined maturity trend upwards. Nevertheless, pebble composition changes in times from Variscan basement pebble-rich to volcanic rock-rich, as a consequence of the basin widening and the dismantling and reworking of the coeval volcanic activity. The sandstone composition clearly changes from quartzolithic to feldspatholithic upwards, as a response to the same change of feeding and reworking of the volcanic rocks. Occasionally, interbedded quartzolithic arenites suggest exceptional floods carrying debris from the far borders of the basin. Also, the immature sandstone composition has been interpreted as being controlled by a continuous supply of fresh debris and to a rapid burial rate. In addition, the disappearance of metaradiolarite(lydite AA) Paleozoic grains in the sandstone mineral suite could represent a distinctive marker of a progressive unroofing of the Variscan chain and a clastic supply from deeper tectonic units.

Ghost Haemoglobin Affecting the Efficacy of Phototherapy

引用

International Journal of Clinical Medicine 2019年第10期10卷 523-530页

作者： Azizullah Langah sara sadiq Ali Akbar Siyal Department of Pediatric Medicine Peoples University of Health Sciences Nawabshah Pakistan Department of Physiology CMH Institute of Medical Sciences Bahawalpur Pakistan.

Introduction: Phototherapy is the treatment of choice for neonatal hyperbilirubinemia. It converts the unconjugated bilirubin from polar and neurotoxic Z-Z-bilirubin to the more polar photobilirubin. It has been hypothesized that high level of hemoglobin or hematocrit interferes in the effectiveness of phototherapy. The objective of the current study is to find out the association of hemoglobin/hematocrit to change in total serum bilirubin concentration during phototherapy. Methods: A prospective cohort study was conducted on 296 neonates with uncomplicated hyperbilirubinemia. Before initiating the phototherapy, hemoglobin, hematocrit and total serum bilirubin levels were measured. After treating the neonates with phototherapy using LED-light for 24 hours, the total serum bilirubin level was measured again. The data were analyzed by using SPSS version-20. Results: The majority of study participants were male (60.8%), with mean postnatal age of 4.66 ±1.65, having mean birth weight of 2.41 ±0.41. Considering Pearson correlation, the hemoglobin had a significant inverse association with ΔTsB0-24 while birth weight and postnatal age also had inverse association but p-values were non-significant, while TsB0 had presented a very weak but significant positive association. The results might be evident of the fact that increase in hemoglobin concentration results in minimal change in total serum bilirubin concentration during phototherapy. Conclusion: Current study found a significant effect of hemoglobin on efficacy of phototherapy, as the change in total serum bilirubin concentration is inversely correlated with the level of hemoglobin. This is important for the physician in treating neonates with hyperbilirubinemia by using phototherapy.
