Review of the Literature on Parental Efficacy and Child Nutrition, Activity, and Weight

Objective: Concern over childhood obesity has driven research to focus on prevention and intervention strategies to curb the epidemic. Parental factors like efficacy have gained attention as this concept is grounded in behavioral change research. Studies have linked efficacy to improved child health behaviors like eating a more nutritious diet and engaging increased physical activity. This leads to a need to examine parental efficacy literature to examine its relationship to childhood obesity. Methods: Six databases including the Psychology and Behavioral Sciences Collection, CINAHL, PubMed, Psychinfo, EBSCOhost, and Onesearch were searched for original research studies examining parental efficacy and child health measures like diet, activity, or weight.Results: Only 16 articles were found that met criteria. This limited research did showcase that higher parental efficacy levels are linked to positive effects, especially regarding improved child diet. There is also evidence of an inverse relationship between higher efficacy and lower child weights and higher efficacy and improved child activity levels, though this was not uniformly found. This review also showcased significant variance in how efficacy is measured and how it is used within studies. Conclusion: Connections between parental efficacy and child healthy behaviors has been established in multiple studies. However, this remains an under-examined area that needs further study to understand how it can be used to improve interventions

Ecology of R Factors

The resistance to antimicrobial drugs and the incidence of R factors were determined in coliform bacteria, isolated from stool and environmental (soil, water) specimens from an urban Xhosa community, as well as from a remote drug-frea Xhosa community in the Transkei. The significant reservoir of R factors in the urban environmental and stool specimens indicates the strong selective force of antimicrobial drugs. This contrasts with the low frequency of R faciors from the remote community and its environment. S. Afr. Med. J., 47, 340 (1973)

Incidence of acute mountain sickness in UK Military Personnel on Mount Kenya.

BACKGROUND: Acute mountain sickness (AMS) is a common problem of trekkers to high altitude. The UK military train at high altitude through adventurous training (AT) or as exercising troops. The ascent of Point Lenana at 4985 m on Mount Kenya is frequently attempted on AT. This study sought to establish the incidence of AMS within this population, to aid future planning for military activities at altitude. METHODS: A voluntary questionnaire was distributed to all British Army Training Unit Kenya based expeditions attempting to ascend Mount Kenya during the period from February to April 2014. The questionnaire included twice daily Lake Louise and Borg (perceived exertion scale) self-scoring. All expeditions were planned around a 5-day schedule, which included reserve time for acclimatisation, illness and inclement weather. RESULTS: Data were collected on 47 participants, 70% of whom reached the summit of Point Lenana. 62% (29/47) self-reported AMS (defined as Lake Louise score (LLS) ≥3) on at least one occasion during the ascent, and 34% (10/29) suffered severe AMS (LLS ≥6). Those who attempted the climb within 2 weeks of arrival in Kenya had a higher incidence of AMS (12/15 (80%) vs 17/32 (53%), p=0.077). Participants recording a high Borg score were significantly more likely to develop AMS (16/18 vs 9/21, p=0.003). CONCLUSIONS: This represents the first informative dataset for Mount Kenya ascents and altitude. The incidence of AMS during AT on Mount Kenya using this ascent profile is high. Adapting the current ascent profile, planning the ascent after time in country and reducing perceived exertion during the trek may reduce the incidence of AMS

Infinite products involving binary digit sums

Let $(u_n)_{n\ge 0}$ denote the Thue-Morse sequence with values $\pm 1$. The Woods-Robbins identity below and several of its generalisations are well-known in the literature \begin{equation*}\label{WR}\prod_{n=0}^\infty\left(\frac{2n+1}{2n+2}\right)^{u_n}=\frac{1}{\sqrt 2}.\end{equation*} No other such product involving a rational function in $n$ and the sequence $u_n$ seems to be known in closed form. To understand these products in detail we study the function \begin{equation*}f(b,c)=\prod_{n=1}^\infty\left(\frac{n+b}{n+c}\right)^{u_n}.\end{equation*} We prove some analytical properties of $f$. We also obtain some new identities similar to the Woods-Robbins product.Comment: Accepted in Proc. AMMCS 2017, updated according to the referees' comment

Brain natriuretic peptide and NT-proBNP levels reflect pulmonary artery systolic pressure in trekkers at high altitude.

Our objective was to evaluate the utility of the natriuretic peptides BNP (brain natriuretic peptide) and NT-proBNP as markers of pulmonary artery systolic pressure (PASP) in trekkers ascending to high altitude (HA). 20 participants had BNP and NT-proBNP assayed and simultaneous echocardiographic assessment of PASP performed during a trek to 5150 m. PASP increased significantly (p=0.006) with ascent from 24+/-4 to 39+/-11 mm Hg at 5150 m. At 5150 m those with a PASP>/=40 mm Hg (n=8) (versus those with PASP/=400 pg/ml) rise in NT-proBNP at 5150 m (n=4) PASP was significantly higher: 45.9+/-7.5 vs. 32.2+/-6.2 mm Hg (p=0.015). BNP and NT-proBNP may reflect elevated PASP, a central feature of high altitude pulmonary oedema, at HA

Due to mine cross cultural living, (I was born in the U.S. but grew in Southeast Asia), I became very interested in the Anthological, Social and Scientific difference between cultures. This led to a historical meta evaluation of humanity in general. Using the principals of Noetic Science, this evaluation reviled the ignorance and down right absence of any educational opportunities to learn the true functional abilities of mankind
