The mediating role of protective factors in relationship between caregiving components and psychosocial adjustment among young carers: a meta-analysis.

OBJECTIVE: Higher youth caregiving is associated with poorer psychosocial outcomes in young carers; hence a research priority is to investigate protective factors that mitigate the adverse effects of youth caregiving. This systematic review with meta-analysis examined the relationships among youth caregiving components and young carer psychosocial adjustment and protective factors, as well as the mediating role of the protective factors in the relationship between caregiving components and psychosocial adjustment. METHODS: Three electronic databases were searched until April 2024 and 10,244 unique publications were identified. Following abstract and title screening, 422 publications were subjected to full-text screening and 60 quantitative studies were included in this study. RESULTS: Meta-analytic structural equation modeling (MASEM) results revealed positive direct effects of caregiving responsibilities and caregiving experiences on benefit finding (&#x3b2;&#xa0;=&#xa0;.43, 95% CI [.074, .782], p&#xa0;<&#xa0;.05) and emotion regulation (&#x3b2;&#xa0;=&#xa0;.72, 95% CI [.44, 1.00], p&#xa0;<&#xa0;.001), respectively. However, there was neither a significant direct effect of caregiving components on psychosocial adjustment nor a significant indirect effect of caregiving components on psychosocial adjustment through benefit finding or emotion regulation. CONCLUSION: Findings revealed a need for research into how caregiving contextual factors affect relations among youth caregiving, protective factors, and adjustment.

Modulation of cross-protection factor(s) of avian Pasteurella multocida.

Cross-protection factor(s) (CPF) of Pasteurella multocida were maintained in vitro through at least 9 serial passages. Different growth media and temperatures enhanced or repressed the ability of P. multocida to produce CPF. Certain amino acids were innoculous to expression of CPF. B-vitamins enhanced CPF, whereas certain inorganic salts repressed CPF. The plasma of normal tuekeys contained a compound or compounds that were responsible for expression and maintenance of CPF.

The variability of the protection factors for sunscreening products.

The variation of the preotection factors for a sunscreening product as determined for different test subjects can be described by a logarithmic normal distribution. It is therefore more appropriate to use logarithmically transformed data for statistical analyses. By means of an analysis of variance it was shown that the influence of the subjects is responsible for only 12% of the total variance, whereas the remaining 88% is due to experimental error. Therefore, the difficulties in determining precise protection factors must be ascribed to deficiencies in the method itself. It was further concluded that correcting the protection factors with respect to a simultaneously measured reference preparation is not a means of improving the precision of the data. The reference substance, if it is included in every measuring series may, however, be used to check the long-term constancy of the method and to compare results from different laboratories.

Breast cancer: potentially predisposing and protecting factors. Role of pregnancy, lactation, and endocrine status.

Risk factors of breast cancer have been correlated with the availability of estradiol and estrone. Mechanisms protecting from breast cancer are thought to be due to the mitotic rest of mammary epithelium (low deoxyribonucleic acid synthesis), as encountered during pregnancy and lactation, and to the actions of estriol and progesterone in opposing the "carcinogenic" estradiol and estrone.

Previous pregnancy as a protective factor against death from melanoma.

Examination of the case-records of women presenting to the Melanoma Unit at Sydney Hospital over the period 1961-71 has shown that women with pregnancies before the development of melanoma had a better survival-rate from melanoma than women without previous pregnancies. The known presence of fetal antigens on melanoma cells and immunisation against fetal antigens during pregnancy suggest an immunological explanation for these results. Exposure to fetal antigens during pregnancy may protect against the dissemination of melanoma cells bearing similar fetal antigens and thus increase the survival-rate. The incidence of melanoma in males and females was approximately equal, which suggests that immune responses to tumour-associated antigens may be more effective in preventing spread of tumours than in preventing their occurrence.

High density lipoprotein as a protective factor against coronary heart disease. The Framingham Study.

Lipid and lipoprotein values, including fasting triglycerides and high density lipoproteins (HDL), low density lipoproteins (LDL) and total cholesterol levels, were obtained on 2,815 men and women aged 49 to 82 years chiefly between 1969 and 1971 at Framingham. In the approximately four years following the characterization of lipids, coronary heart disease developed in 79 of the 1,025 men and 63 of the 1,445 women free of coronary heart diseases. At these older ages the major potent lipid risk factor was HDL cholesterol, which had an inverse association with the incidence of coronary heart disease (p less than 0.001) in either men or women. This lipid was associated with each major manifestation of coronary heart disease. These associations were equally significant even when other lipids and other standard risk factors for coronary heart disease were taken into consideration. A weaker association with the incidence of coronary heart disease (p less than 0.05) was observed for LDL cholesterol. Triglycerides were associated with the incidence of coronary heart disease only in women and then only when the level of other lipids was not taken into account. At these ages total cholesterol was not associated with the risk of coronary heart disease.
