Occupational Burnout Among Obstetrics And Gynaecology Healthcare Professionals In A Public Hospital In Islamabad, Pakistan.

To assess burnout by the extent of exhaustion and disengagement, and to compare the two elements among obstetrics and gynaecology healthcare professionals. The cross-sectionalstudy was conducted at the Federal Government Polyclinic Hospital, Islamabad, Pakistan, in July and August, 2020 during the coronavirus disease-2019 pandemic, and comprised healthcare professionals from the obstetrics and gynaecology department. Data was collected online using the 25-item Oldenburg Burnout Inventory. Data was analysed using SPSS 26. Ofthe 142 individuals approached, 102(71.83%)responded; 55(53.92%) doctors, 43(42.15%) nurses and 4(3.92%) operation theatre technicians. Overall, there were 98(96.1%) females, and 67(65.7%) married subjects. Mean exhaustion scorewas 2.53±0.54 anddisengagementscorewas 2.14±0.57. Burnoutwasfoundin40(39.2%)participants, 83 (81.4%)were exhausted, 44(43.1%)weredisengaged, and4(3.1%)weredisengagedbutnot exhausted. Participants aged>50 yearswere significantly more exhausted and disengaged than the younger ones(p<0.05). Those with work hours >60 per week were significantly more exhausted and disengaged than the rest (p<0.05). Health care professionals inobstetrics and gynaecology teams showed considerably highburnout levels during the coronavirus disease-2019 pandemic in Pakistan.

The Impact of Nitrogen Plasma Treatment upon the Physical-Chemical and Dyeing Properties of Wool Fabric

Pretreatment of wool fabric with low-temperature plasma (LTP) as an eco-friendly process was tested. The impact of plasma-treatment parameters on the surface morphology, physical-chemical, and dyeing properties of wool using anionic dyes were investigated. The LTP-treatment resulted in a dramatic improvement in fabric hydrophilicity and wettability, the removal of fiber surface material, and creation of new active sites along with improved initial dyeing rate. The nature of the plasma gas governed the final exhaustion percentage of the used acid dyes according to the following descending order: nitrogen plasma > nitrogen/oxygen (50/50) plasma > oxygen plasma > argon plasma ≥ control. Prolonging the exposure time up to 20 minutes resulted in a gradual improvement in the extent of exhaustion. Increasing the ageing period up to 100 hours resulted in a slight decrease in the extent of acid dye uptake. Increasing the salt concentration up to 5 g/L and the dyeing temperature up to 95°C resulted in an enhancement in the extent of exhaustion. The extent of improvement in dye bath exhaustion, using low temperature nitrogen plasma (LTNP)-treatment, was determined by the nature of the anionic dyes.

Exhaustion is associated with reduced habituation of free cortisol responses to repeated acute psychosocial stress

We investigated the association between exhaustion and the habituation of free cortisol responses to repeated stress exposure. The study comprised 25 healthy male subjects (38–59 years) who were confronted three times with the Trier Social Stress Test. Mean cortisol responses showed the well-known general habituation effect. A two-way interaction day by exhaustion ( p < 0.05) indicated that mean cortisol responses vary across stress sessions depending on the extent of exhaustion. Linear regression revealed a negative dose–response relationship between exhaustion and the degree of habituation ( p < 0.02). We identified 19 individuals showing a response habituation (negative slope) and 6 individuals showing a response sensitization over the three sessions (positive slope) with the latter reporting higher exhaustion scores. It might be hypothesized that impaired habituation to repeated exposure to the same stressor could reflect a state of increased vulnerability for allostatic load. Absence of normal habituation might be one potential mechanism how exhaustion relates to increased disease vulnerability.

Dyeing properties of nylon 66 nano fiber with high molecular mass acid dyes

Research and development of nano fiber products is very active over the world. Physical characteristics and dyeing properties of nylon 66 nano fiber were investigated in this study. X-ray diffraction, DSC, analysis of amino end group, and water absorption were performed to get information concerning physical properties of nano fiber. Nylon 66 nano fiber was dyed with high molecular mass acid dyes. Effects of dyeing temperature, pH of dyeing solution, and concentration of acid dyes on dyeing properties such as rate of dyeing and the extent of exhaustion, were examined and compared to those of regular fiber. It was found that nano fiber adsorbed acid dyes at lower temperature, got rapidly dyed, and its extents of exhaustion at specific dyeing temperature were higher than regular fiber. It was also observed that nano fiber could adsorb a large amount of acid dye without a significant loss in the extent of exhaustion. Washing fastness of the dyed nano fiber was lower by 1/2∼1 grade, light fastness by 1 grade than the dyed regular fiber.

Reactive Dyes for Wool

Several α-bromoanthraquinone derivatives and quinizarin-2-sulfonic acid have been found to react with the thiol (cysteine) parts of wool. The dyeing properties (extent of exhaustion and fixation) and the light fastness of the dyeings have been studied.

The Application of Logwood to Wool

The fastness properties of logwood on various metallic) mordants have been studied, particular attention having been paid to fastness to light. The possibility of dyeing logwood blacks by a one–bath method based on the Bonsor process has been investigated in detail. Using a colorimetrio method for the estimation of hæmatein, its rate of exhaustion on various mordants and the influence of the pH of the dyebath on the extent of exhaustion have been determined.
