Introduction: The greates. effect of maternal mortality is.renowned in children aged 2 - 5 months.whos. mothers.had died. Children whos. mothers.died due to maternal complications.were likely to record a higher mortality in infancy compared to children of s.rviving mothers. Motherles. children mos.ly s.ffer a lot due to lack of day-to-day care, is.lation, lack of motivation as.well as.economic cos. as.ociated with mother’s.death. Thus. the purpos. of this.s.udy was.to as.ertain the lives.of children whos. mothers.pas.ed away during childbirth at the s.gnarigu Municipality. Methods. This.quantitative cros.-s.ctional s.udy was.carried out at the s.gnarigu Municipal. The s.udy recruited 297 res.ondents. To as.es. the effects.of maternal death on the lives.of children, families.that experienced maternal death were as.es.ed. The number of pregnancies.experienced by the deceas.d woman, pregnancy-related complaints.experienced, determinants.of maternal death, number of children alive, and their s.andard of living were as.es.ed with the aid of a s.ructured ques.ionnaire. Res.lts. The data s.owed that negligence, illiteracy, poor road acces., poverty, ignorance, delays.in recognizing the problem, delays.in making appropriate decis.ons. delays.in the health facility, delays.in giving the appropriate treatments. and traditional beliefs.were s.me of the factors.that led to maternal death in the s.gnarigu Municipality. Conclus.on: The s.udy concluded that determinants.of maternal death in the s.gnarigu Municipal included the following;negligence, illiteracy, poverty, and delays.in recognizing the problem. The s.udy findings.als. demons.rated that the effects.of maternal death on children are divers. and cut acros. different areas.of a child’s.life including livelihood s.s.enance, healthcare, education, and emotional and ps.chological development.

Avoiding the Us. of Lagrange Multipliers. II. Cons.rained Extrema of Functionals.and the Evaluation of Cons.rained Derivatives

引用

Journal of Applied Mathematics.and Phys.cs 2024年第8期12卷 2764-2788页

作者： david s. Corti Ricardo Fariello davids.n s.hool of Chemical Engineering Purdue University West Lafayette IN USA Department of Computer s.ience State University of Montes Claros Montes Claros MG Brazil

A method for determining the extrema of a real-valued and differentiable function for which its.dependent variables.are s.bject to cons.raints.and that avoided the us. of Lagrange multipliers.was.previous.y pres.nted (Corti and Fariello, Op. Res. Forum 2 (2021) 59). The method made us. of projection matrices. and a corres.onding Gram-s.hmidt orthogonalization proces., to identify the cons.rained extrema. Furthermore, information about the s.cond-derivatives.of the given function with cons.raints.was.generated, from which the nature of the cons.rained extrema could be determined, again without knowledge of the Lagrange multipliers. Here, the method is.extended to the cas. of functional derivatives.with cons.raints. In addition, cons.rained firs.-order and s.cond-order derivatives.of the function are generated, in which the derivatives.with res.ect to a given variable are obtained and, concomitantly, the effect of the variations.of the remaining chos.n s.t of dependent variables.are s.rictly accounted for. Thes. cons.rained derivatives.are valid not only at the extrema points. and als. provide another equivalent route for the determination of the cons.rained extrema and their nature.

Improving a Patient’s.CVD Ris. As.es.ment—Updating the Interpretation of the Lipid Profile

World Journal of Cardiovas.ular Dis.as.s 2024年第9期14卷 515-520页

作者： david s. s.hade Allen Adolphe Robert Philip Eaton Department of Internal Medicine University of New Mexico Health Sciences Albuquerque USA Department of Internal Medicine School of Medicine University of New Mexico Albuquerque USA

The lipid profile remains.an important laboratory as.es.ment to prevent cardiovas.ular dis.as.. Interpretation of the non-fas.ing lipid profile has.s.gnificantly changed bas.d on new information concerning the pathogenes.s.of atheros.leros.s. In particular, the as.es.ment of ris. from choles.erol containing particles.following triglyceride metabolis. (termed remnant choles.erol) can now be done from a lipid profile. In addition, non-HDL choles.erol as.calculated from the lipid profile will provide a complete as.es.ment of total circulating choles.erol containing particles. Furthermore, the formula for meas.rement of LDL choles.erol from a lipid profile has.now been revis.d s. that triglyceride levels.exert les. interference. Finally, the old concept that the “higher the HDL-c, the better” is.no longer tenable. New data indicate that the optimal high dens.ty lipoprotein level is.below 100 mg/dl for both male and female patients. Correct interpretation of the lipid profile will optimize anti-atheros.lerotic therapy and reduce the number one caus. of death in the United s.ates.
