Universal and Near-Universal Cycles of Set Partitions

We study universal cycles of the set ${\cal P}(n,k)$ of $k$-partitions of the set $[n]:=\{1,2,\ldots,n\}$ and prove that the transition digraph associated with ${\cal P}(n,k)$ is Eulerian. But this does not imply that universal cycles (or ucycles) exist, since vertices represent equivalence classes of partitions! We use this result to prove, however, that ucycles of ${\cal P}(n,k)$ exist for all $n \geq 3$ when $k=2$. We reprove that they exist for odd $n$ when $k = n-1$ and that they do not exist for even $n$ when $k = n-1$. An infinite family of $(n,k)$ for which ucycles do not exist is shown to be those pairs for which $S(n-2, k-2)$ is odd ($3 \leq k < n-1$). We also show that there exist universal cycles of partitions of $[n]$ into $k$ subsets of distinct sizes when $k$ is sufficiently smaller than $n$, and therefore that there exist universal packings of the partitions in ${\cal P}(n,k)$. An analogous result for coverings completes the investigation.Comment: 22 page

Renal Replacement Therapy in Children in the Developing World: Challenges and Outcome in a Tertiary Hospital in Southeast Nigeria

A 5-year observational, retrospective study was conducted to evaluate the indications, the availability, the accessibility, the sustainability, and the outcome of children managed for acute kidney injury (AKI) and end stage kidney disease (ESKD) who required renal replacement therapy RRT in Enugu, southeast Nigeria. A total of 64 patients aged 5 months to 16 years required RRT, of which only 25 underwent RRT, giving an RRT accessibility rate of 39.1%. Eleven (44%) patients required chronic dialysis program/ renal transplant, of which only 1 (9.1%) accessed and sustained chronic hemodialysis, giving a dialysis acceptance rate of 9.1%. Fifty (78%) of the patients belonged to the low socioeconomic class. Thirty-three (51.5%) could not access RRT because of financial constraints and discharge against medical advice (DAMA); 6 (9.4%) died on admission while sourcing for funds to access the therapy; 5 (7.8%) died while on RRT; 9 (14.1%) improved and were discharged for follow-up; 1 (1.6%) improved and was discharged to be on chronic dialysis program while awaiting renal transplantation outside the country/clinic follow-up, while the remaining 10 (15.6%) were unable to sustain chronic dialysis program or access renal transplantation and were lost to follow-up. We conclude that RRT remains unaffordable within the subregion

Exercícios aquáticos na gestação: relatos de uma série de mulheres

The aquatic exercises have been sought more and more by pregnant women and recommended by Obstetricians with the purpose of obtaining a better life quality during the period of pregnancy. With the objective of describing the pregnant women's experience that practice aquatic exercises during the pregnancy, a study observational was accomplished, traverse and prospective using a qualitative approach through a questionnaire with 58 pregnant that were practicing aquatic exercises there is at least two months. The study revealed that all the pregnant women interviewees possess positive experience as the practice of the aquatic exercises in the gestation.Os exercícios aquáticos vem sendo cada vez mais procurados por gestantes e recomendado por Obstetras com a finalidade de obter uma melhor qualidade de vida durante o período gestacional. Com o objetivo de descrever a experiência de gestantes que praticam exercícios aquáticos durante a gestação, foi realizado um estudo observacional, transversal e prospectivo utilizando uma abordagem qualitativa através de um questionário com 58 gestantes que estavam praticando exercícios aquáticos há pelo menos dois meses. Este estudo revelou que todas as gestantes entrevistadas possuem experiência positivas quanto a prática dos exercícios aquáticos na gestação

Management of severe tetanus using magnesium sulfate – The experience in a tertiary health institution in Southern Nigeria

Tetanus is a vaccine-preventable disease caused by the neurotoxin of Clostridium tetani: A motile, Gram-positive, sporeforming&nbsp;obligate anaerobe commonly found in the soil, dust, and alimentary canals of various animals. It remains a public health&nbsp;challenge in the developing countries as the morbidity and mortality rates remain high unlike in the developed world where the&nbsp;incidence is markedly low and no longer contributory to significant mortality. We report two male adolescents admitted in the&nbsp;pediatric department of a tertiary medical center of Nigeria for severe tetanus following an open injury to the limbs. Due to poor&nbsp;response to initial management with the combination of chlorpromazine, phenobarbitone, and diazepam, the latter was replaced&nbsp;with continuous infusion of magnesium sulfate after a loading dose was administered. Both the patients recovered without any&nbsp;prevailing complications and were discharged after 26 and 50 days of hospitalization, respectively, after receiving tetanus toxoid&nbsp;and were subsequently followed up. Successful severe tetanus management without the use of sophisticated medical gadgets and&nbsp;expensive treatment in a resource-poor economy is achievable as demonstrated by our study with the use of magnesium sulfate&nbsp;infusion

Quality indicators in support of intravenous therapy in a university hospital: a contribution of nursing

Objectives: to understand the indicators of quality of care for intravenous therapy in the neonatal intensive care unit of a university hospital. Method: a non-experimental descriptive study with a quantitative approach in the NICU of a university hospital, through a systematic survey on the protocol of intravenous care: peripheral venous access, PICC and central venous catheter. Excel and presented in tables - statistical treatment, where the data were pooled and processed in Microsoft Office program was conducted. The study was approved by the CEP HUAP/UFF under Protocol 01660412.9.0000.5243 . Results: in the data analysis, the results showed a greater need for technical training and maintenance of venous access catheter peripheral, PICC, and umbilical catheter. Conclusion: so, the health professional should facilitate and promote patient safety for the sake of your well being and quality of life, avoiding the risks and adverse effects

The quality of an integrated network: accessibility and coverage in prenatal care

Objective: analyzing the values expressed in the speech of women/mothers in the accessibility of monitoring examinations of prenatal care. Method: a phenomenological, descriptive, exploratory study with a qualitative approach. There were interviwed fifty women/pregnant of the Prenatal Program of Niteroi, Rio de Janeiro, Brazil. The data analyzed allowed formulating themes articulated with the Theory of Values. Results: barriers experienced by women on laboratory/images examinations: delay in results, misinformation and lack of a service of quality, a value considered of vital use for them. We realize the need for change in monitoring prenatal, considering a network of unified and integrated health with quality services at different levels of care, promoting wellness, comfort and safety to pregnant women as a vital value to their health. Conclusion: the health network should be unified for a better quality of services offered to women
