Religiosity, Spirituality, and Death Anxiety Among Filipino Older Adults: A Correlational Study.

The concept of death anxiety is expected of older persons as they age and are nearing their end-of-life. This study examined the relationship between religiosity, spirituality, and death anxiety among Filipino older adults. A convenience sample of 125 Filipino older adults were recruited in the study. Data were collected using the Spirituality Scale, Revised Death Anxiety Scale, and Dimensions of Religiosity Scale. Results of the study revealed that spirituality (r=-0.168, p = 0.061) and religiosity (r=-0.044, p = 0.623) had an inverse relationship with death anxiety. However, even with the inverse relationship, spirituality and religiosity were not significantly correlated with death anxiety, although participants were well aware of the importance of these concepts on their lives. It is suggested that assessing spirituality and religiosity of this age group can inform nurses to engage in quality nursing practice, by affirming the vulnerability, and preserving the personhood of older persons as they near their end-of-life.

Spiritual well-being, self-transcendence, and spiritual practices among Filipino women with breast cancer.

OBJECTIVE: The study was conducted in order to determine the relationship between spiritual well-being and self-transcendence and to identify the spiritual practices utilized by Filipino patients who are recovering from breast cancer. METHODS: A descriptive correlational study was used, and a purposive sampling technique was utilized to select the participants in the study. Data were collected using self-administered questionnaires and were analyzed using frequency, percentage, mean, standard deviation, and Pearson's r correlation. RESULTS: The study revealed that the overall mean score of the spiritual index of well-being among the participants was 4.41 (±0.54), while the mean score of self-transcendence was 3.64 (±0.50). The results showed that there was a significant relationship between spirituality and self-transcendence among Filipino women with breast cancer. SIGNIFICANCE OF RESULTS: Filipino women with breast cancer rely on their spirituality, which enables them to find meaning in their illness. Hence, assessing spirituality among this population group will enable nurses to provide holistic nursing care, as this can help them cope with the challenges associated with their illness.

Protective effect of sulfurous water in peripheral blood mononuclear cells of Alzheimer's disease patients.

AIMS: One of the main features of sulfurous water (SW) is the presence of hydrogen sulfide (H2S), which confers its antioxidant activity. Since oxidative stress plays an important role in Alzheimer's disease (AD) we hypothesize that SW could have a protective effect in these patients. MATERIAL AND METHODS: A therapeutic in vitro approach of SW was performed in peripheral blood mononuclear cells (PBMCs) of AD patients and in age-matched healthy non-demented controls using one modification of the comet assay (to measure oxidative DNA damage) and the MTT assay (as an indicator of cell viability). Hydrogen peroxide and homocysteine were used to induce oxidative DNA damage, and vitamin C, Trolox and N-acetyl-cysteine were selected as antioxidants of reference to compare SW treatment results. KEY FINDINGS: SW did not increase per se the oxidative DNA damage of PBMC. Furthermore, SW protected them against enhanced oxidative stress in AD and control populations after pro-oxidant stimuli, with similar results to those observed when using the antioxidants of reference. Nevertheless, SW was the only treatment that could avoid the loss of viability of PBMC for all pro-oxidant stimuli in both populations, suggesting that H2S could confer to SW a more antioxidant capacity than other known antioxidants. SIGNIFICANCE: The protective effect of SW was proved for the first time not only in DNA stability but also in cell viability preservation in AD, indicating that further research in other in vitro and in vivo models could lead to include SW as a possible therapy for AD.

Deep subsurface sulfate reduction and methanogenesis in the Iberian Pyrite Belt revealed through geochemistry and molecular biomarkers.

The Iberian Pyrite Belt (IPB, southwest of Spain), the largest known massive sulfide deposit, fuels a rich chemolithotrophic microbial community in the Río Tinto area. However, the geomicrobiology of its deep subsurface is still unexplored. Herein, we report on the geochemistry and prokaryotic diversity in the subsurface (down to a depth of 166 m) of the Iberian Pyritic belt using an array of geochemical and complementary molecular ecology techniques. Using an antibody microarray, we detected polymeric biomarkers (lipoteichoic acids and peptidoglycan) from Gram-positive bacteria throughout the borehole. DNA microarray hybridization confirmed the presence of members of methane oxidizers, sulfate-reducers, metal and sulfur oxidizers, and methanogenic Euryarchaeota. DNA sequences from denitrifying and hydrogenotrophic bacteria were also identified. FISH hybridization revealed live bacterial clusters associated with microniches on mineral surfaces. These results, together with measures of the geochemical parameters in the borehole, allowed us to create a preliminary scheme of the biogeochemical processes that could be operating in the deep subsurface of the Iberian Pyrite Belt, including microbial metabolisms such as sulfate reduction, methanogenesis and anaerobic methane oxidation.

The distribution of 5-methylcytosine in the nuclear genome of plants.

We have determined the 5-methylcytosine (5mC) content in high molecular weight DNA, from two dicot (tobacco and pea) and two monocot (wheat and maize) plant species, fractionated according to base composition. The results show that the proportion of 5mC in the genomic fractions increases linearly with their guanine + cytosine (G + C) content while the proportion of non-methylated cytosine remains almost constant. This can be interpreted as a consequence of a difference in mutation pressure related to spontaneous deamination of 5mC to thymine between the different compartments of plant genomes.

Placebo-controlled trial of nimodipine in the treatment of acute ischemic cerebral infarction.

Nimodipine is a 1,4-dihydropyridine derivative that shows a preferential cerebrovascular activity in experimental animals. Clinical data suggest that nimodipine has a beneficial effect on the neurologic outcome of patients suffering an acute ischemic stroke. Our double-blind placebo-controlled multicenter trial was designed to assess the effects of oral nimodipine on the mortality rate and neurologic outcome of patients with an acute ischemic stroke. One hundred sixty-four patients were randomly allocated to receive either nimodipine tablets (30 mg q.i.d.) or identical placebo tablets for 28 days. Treatment was always started less than or equal to 48 hours after the acute event. The Mathew Scale, slightly modified by Gelmers et al, was used for neurologic assessment. Mortality rate and neurologic outcome after 28 days were used as evaluation criteria. We considered 123 patients to be valid for the analysis of efficacy. Mortality rates did not differ significantly between groups. Neurologic outcome after 28 days of therapy did not differ between groups. However, when only those patients most likely to benefit from any intervention (Mathew Scale sum score of less than or equal to 65 at baseline) were analyzed separately in post hoc-defined subgroups, the nimodipine-treated subgroups showed a significantly better neurologic outcome. This result suggests that some patients with acute ischemic stroke will benefit from treatment with nimodipine tablets.
