The large population of human congestion in Makkah during Hajj would promote contagious diseases. Thus, the pilgrims require health care services that are efficient, effective, and high quality. The aim of this study is to determine the type of health-related problems among Malaysian pilgrims and to identify the health care services required by them during Hajj in Makkah. A cross-sectional study was conducted in which involved 379 Malaysian pilgrims in 2013/14234H. The survey was conducted after the pilgrims completed their Hajj ritual. A total of 400 sets of questionnaires were distributed at Abraj Janadriyah Hotel, which was occupied by more than 3000 Malaysian pilgrims. The response rate for this survey was 93%. Male respondents were constituted of 49.6% and female respondents were 50.4% with the mean age 52 years old. The underlying disease among Malaysian pilgrims during Hajj was respiratory disease (77.5%). The demands for health personnel (36.1%) and quality medication (34.7%) are among the important healthcare services required by the Malaysian pilgrims in Makkah. Respiratory disease is a common disease experienced by Malaysian pilgrims in Makkah. A certain types of services such as health personnel and quality medicine are strongly demanded by the Malaysian pilgrims to overcome their health problem during Hajj. This research provides a fundamental input to the health care providers, and also benefited the Hajj management authority to improve the quality of hajj management in future.
Hajj and ‘Umrah pilgrimage are a huge congregation performed by Muslims in Makkah, Saudi Arabia. The pilgrimage causes overcrowding and congestion that can lead to a high risk of health problems, especially when pilgrims have health problems. The purpose of this study is to assess the reliability of EQ-5D as a measuring tool to capture the health status of the pilgrims. Data collection was done during Ramadhan’s ‘Umrah in 2014. In this cross-sectional study, a total of 300 self-administered questionnaires attached with the EQ-5D-5L questions were distributed to Malaysian ‘Umrah pilgrims in Makkah and willing to participate in the study. The outcomes from the questionnaires and EQ-5D-5L were systematically analysed by using the SPSS software. The response rate was 64%, involved female (53%) and male (47%) respondents with the mean age of 55 years old. Hypertension (21.5%) and diabetes (16.2%) were the commonest underlying health problems suffered by the respondents in this study. Based on the EQ-5D outcomes, 53.3% of the respondents had no problem in their movement. However, the mean of EQ-VAS (visual analogue scale) presented 83 out of 100 scaling point, which means they might have problems in their health status. In addition, this study revealed, respondents with underlying illnesses had difficulty in some dimensions in EQ-5D. Hypertension was identified as the commonest underlying disease amongst the pilgrims. A contradicted outcome from the objective and subjective measuring scales of EQ-5D and EQ-VAS respectively; presented its sensitivity of EuroQol as a measuring tool for the quality of life among pilgrims living within such congestion.
Effects of metsulphuron-methyl on the activities of amylase, invertase and xylanase in loamy sand and clay were evaluated for up to 28 days under laboratory conditions. Metsulphuron-methyl at 1.0 microg/g caused a significant reduction in amylase, invertase and xylanase activities for the entire period of study, especially at 28 days incubation in both soils. The lowest activities of the three enzymes were observed in the presence of 5.0 microg/g at 28 days incubation.
The effect of human normal serum (HNS) on Pseudomonas pseudomallei was determined. It is apparent from our data that the organism is resistant to the normal serum bactericidal mechanism. Ancillary experiments to confirm this serum-resistant property of P. pseudomallei were done by examining the effects of growth phase conditions of the bacteria (i.e., logarithmic and stationary phases) and different buffered systems used as diluent in our bactericidal assay. Results obtained showed similar degree of resistance to serum bactericidal killing by 5 strains of the organisms tested. The possible survival advantage of serum-resistance property to P. pseudomallei as bacterial pathogens known to invade the blood stream is discussed.
Lipid biosynthesis and fatty acids composition of oleaginous zygomycetes, namely Cunninghamella bainieri 2A1, cultured in media with excess or limited nitrogen were quantitatively determined at different times of culture growth. Accumulation of lipids occurred even when the activity of NAD(+)-ICDH (β-Nicotinamide adenine dinucleotide-isocitrate dehydrogenase) was still detectable in both media. In C. bainieri 2A1, under nitrogen limitation, the ratio of lipids was around 35%, whereas in nitrogen excess medium (feeding media supplemented with ammonium tartarate), the lipid ratio decreased. The amount of this decrease depended on the level of ammonium tartarate in the media. The main findings in this paper were that C. bainieri 2A1 has the ability to accumulate lipid although nitrogen concentration detected inside the media and that NAD-ICDH was active in all culture periods. These results proved that the strain C. bainieri 2A1 has an alternative behavior in lipid biosynthesis that differs from yeast. According to the old hypotheses, yeasts could not accumulate lipid more than 10% when nitrogen was detected inside the media. Nitrogen-limited and excess media both contained the same fatty acids (palmitic acid, stearic acid, olic acid, linoleic acid and γ-linolenic acid), but at different concentrations. The C:N ratio was also studied and showed no effects on total lipid accumulation, but a significant effect on γ-linolenic acid concentration.
Strategic feeding of ammonium and metal ions (Mg(2+), Mn(2+), Fe(3+), Cu(2+), Ca(2+), Co(2+), and Zn(2+)) for enhanced GLA-rich lipid accumulation in C. bainieri 2A1 was established. When cultivated in nitrogen-limited medium, the fungus produced up to 30% lipid (g/g biomass) with 12.9% (g/g lipid) GLA. However, the accumulation of lipid stopped at 48 hours of cultivation although glucose was abundant. This event occurred in parallel to the diminishing activity of malic enzyme (ME), fatty acid synthase (FAS), and ATP citrate lyase (ACL) as well as the depletion of metal ions in the medium. Reinstatement of the enzymes activities was achieved by feeding of ammonium tartrate, but no increment in the lipid content was observed. However, increment in lipid content from 32% to 50% (g/g biomass) with 13.2% GLA was achieved when simultaneous feeding of ammonium, glucose, and metal ions was carried out. This showed that the cessation of lipid accumulation was caused by diminishing activities of the enzymes as well as depletion of the metal ions in the medium. Therefore, strategic feeding of ammonium and metal ions successfully reinstated enzymes activities and enhanced GLA-rich lipid accumulation in C. bainieri 2A1.
