What about the mother and family when an infant doesn`t sleep?

Becoming a new parent is a time of enormous change in the lifestyle of women, particularly as women are expected to take on prime responsibly for caring for the child. Motherhood can be exhausting and lonely as women cope with the demands of a new baby. These demands are exacerbated when infants do not sleep. This causes many parents to seek professional intervention with persistent infant sleep problems. Through focus group interviews, this study sought to understand the experiences of 28 women and families in how they coped with and managed an infant with sleep problems. Results indicated that women experienced major role confusion as they internalised the image that 'a good mother does it all'. Persistent infant crying and their own sleep deprivation exacerbated their loss of identity and shattered their self image, and caused anger and confusion in some partners. Each woman sought primary health care support through a five day residential stay in an Early Parenting Centre in Victoria. The women found that this professional support facilitated confidence building and feelings of normality. Most important, staff encouraged the women to feel good about themselves and their ability to manage future sleep problems.

Sleep duration and risk of obesity among a sample of Victorian school children

BACKGROUND: Insufficient sleep is potentially an important modifiable risk factor for obesity and poor physical activity and sedentary behaviours among children. However, inconsistencies across studies highlight the need for more objective measures. This paper examines the relationship between sleep duration and objectively measured physical activity, sedentary time and weight status, among a sample of Victorian Primary School children.

METHODS: A sub-sample of 298 grades four (n = 157) and six (n = 132) Victorian primary school children (aged 9.2-13.2 years) with complete accelerometry and anthropometry data, from 39 schools, were taken from a pilot study of a larger state based cluster randomized control trial in 2013. Data comprised: researcher measured height and weight; accelerometry derived physical activity and sedentary time; and self-reported sleep duration and hypothesised confounding factors (e.g. age, gender and environmental factors).

RESULTS: Compared with sufficient sleepers (67 %), those with insufficient sleep (<10 hrs/day) were significantly more likely to be overweight (OR 1.97, 95 % CI:1.11-3.48) or obese (OR 2.43, 95 % CI:1.26-4.71). No association between sleep and objectively measured physical activity levels or sedentary time was found.

CONCLUSION: The strong positive relationship between weight status and sleep deprivation merits further research though PA and sedentary time do not seem to be involved in the relationship. Strategies to improve sleep duration may help obesity prevention initiatives in the future.

Presleep activities and time of sleep onset in children

OBJECTIVE: Presleep activities have been implicated in the declining sleep duration of young people. A use-of-time approach may be used to describe the presleep period. The study aims were to describe the activities undertaken 90 minutes before sleep onset and to examine the association between activities and time of sleep onset in New Zealand young people. METHODS: Participants (N = 2017; 5-18 years) self-reported their time use as part of a national survey. All activities reported in the 90 minutes before sleep were extracted. The top 20 activities were grouped into 3 behavioral sets: screen sedentary time, nonscreen sedentary time, and self-care. An adjusted regression model was used to estimate presleep time spent in each behavioral set for 4 distinct categories of sleep onset (very early, early, late, or very late), and the differences between sleep onset categories were tested. RESULTS: In the entire sample, television watching was the most commonly reported activity, and screen sedentary time accounted for ∼30 minutes of the 90-minute presleep period. Participants with a later sleep onset had significantly greater engagement in screen time than those with an earlier sleep onset. Conversely, those with an earlier sleep onset spent significantly greater time in nonscreen sedentary activities and self-care. CONCLUSIONS: Screen sedentary time dominated the presleep period in this sample and was associated with a later sleep onset. The development of interventions to reduce screen-based behaviors in the presleep period may promote earlier sleep onset and ultimately improved sleep duration in young people.

A preventative approach to oral health for children in a regional/rural community in south-west Victoria Australia

Abstract Dental caries is a major health problem in most industrialised countries. Childhood dental disease can cause acute pain, difficulty eating resulting in reduced self-esteem and sleep deprivation. The treatment of oral disease using traditional methods is costly and in industrialized countries currently rates the fourth most expensive disease to treat. Dental professionals are currently facing an unfathomable task of how to manage the large burden of consequences associated with caries progression across the world. The Barwon South-West Region of Victoria, Australia is a diverse regional/rural area. Some communities are quite remote. Barwon Health and Colac Area Health Oral Health Services developed an outreach program to improve access to dental services for children. A Minimal Intervention Dentistry approach was incorporated and includes early diagnosis, risk assessment, early detection of mineral loss, non-surgical treatment and preservation of the tooth structure. Kindergartens throughout the region and children in the first year of Primary School are visited by Oral Health Therapists. Teeth are scored according to the International Caries Detection Assessment System and any early 'white spot' lesions identified have fluoride varnish applied. Children receive up to three dental check-ups during the year and given a toothbrush and toothpaste at each visit. Parent engagement sessions are conducted during Visit 2. Examinations and fluoride application take only 3 - 6 minutes for each child, compared with the usual 30 minute appointments in dental clinics. Two virtual chairs have been created as two dental teams visit Kindergartens throughout the Barwon Region, significantly easing pressure at Community dental clinics. The Kinder Wide Smiles program successfully intervened in the oral health of 5,305 children in the region. Most importantly, one of the barriers for children not presenting to static dental clinics for screening has been eliminated.

How do early parenting centres support women with an infant who has a sleep problem?

Some women who have an infant experiencing sleep problems are so sleep deprived themselves that admission to an early parenting centre is needed to help them better manage the situation. This paper reports on a qualitative study that used focus group methods to interview familes who were admitted to an early parenting centre for persistent infant sleep problems. Results showed that parents needed a variety of strategies such as instructional, emotional and physical supports to develop confidence to manage infant's sleep disturbance at home.

Coping with economic deprivation during unemployment

The negative impact of unemployment on psychological health is well known. Less is known of the ways that people cope with the problems associated with unemployment, one of which is economic deprivation. This study examined the interrelationships between employment status (200 unemployed participants and 128 employed participants), economic deprivation, coping-efforts and psychological health. It also examined the moderating effect of coping on the relationship between economic deprivation (restriction of spending for material necessities and restriction of spending for meaningful leisure activity) and psychological health. The results suggest that economic deprivation is experienced differentially in terms of material necessities and meaningful leisure activities with unemployed respondents differing from employed on levels of deprivation for meaningful leisure activities but not for material necessities. Employment status, economic deprivation for meaningful leisure activity, solution-oriented coping and affective-based coping significantly predicted depressive affect and self-esteem. Depressive affect was also predicted by economic deprivation for material necessities. A number of significant two-way interactions show that the relationship between economic deprivation and psychological health was conditional upon the use of solution-oriented coping. Results also showed that the relationship between employment status and depressive affect was moderated by the use of affective-based coping. The incorporation of these findings into intervention programmes for unemployed persons is discussed.

Predicting self-esteem during unemployment: the effect of gender, financial deprivation, alternate roles, and social support

Two hundred and one unemployed men and women participated in a cross-sectional study that assessed self-esteem, financial deprivation, number of alternate roles, and use of social support. Financial deprivation, alternate roles, and social support each had a main effect on self-esteem. In addition, these variables interacted with gender to affect self-esteem. Specifically, financial deprivation had a greater negative association with self-esteem in men as compared with women. In contrast, alternate roles and social support had a stronger positive relationship to self-esteem in women than in men. The incorporation of these findings into intervention programs for unemployed persons is discussed.

The effect of water deprivation on the expression of atrial natriuretic pepide and its receptors in the spinifex hopping mouse, Notomys alexis

This study investigated the mRNA expression of the atrial natriuretic peptide (ANP) system (peptide and receptors) during water deprivation in the spinifex hopping mouse, Notomys alexis, a native of central and western Australia that is well adapted to survive in arid environments. Initially, ANP, NPR-A and NPR-C cDNAs (partial for receptors) were cloned and sequenced, and were shown to have high homology with those of rat and mouse. Using a semi-quantitative multiplex PCR technique, the expression of cardiac ANP mRNA and renal ANP, NPR-A, and NPR-C mRNA was determined in 7- and 14-day water-deprived hopping mice, in parallel with control mice (access to water). The levels of ANP mRNA expression in the heart remained unchanged, but in the kidney ANP mRNA levels were increased in the 7-day water-deprived mice, and were significantly decreased in the 14-day water-deprived mice. NPR-A mRNA levels were significantly higher in 7-day water-deprived mice while no change for NPR-A mRNA expression was observed in 14-day water-deprived mice. No variation in NPR-C mRNA levels was observed. This study shows that water deprivation differentially affects the expression of the ANP system, and that renal ANP expression is more important than cardiac ANP in the physiological adjustment to water deprivation.

Renal C-type natriuretic peptide and natriuretic peptide receptor B mRNA expression are affected by water deprivation in the Spinifex Hopping mouse

This study investigated the effect of water deprivation on the expression of C-type natriuretic peptide (CNP) and natriuretic peptide receptor B (NPR-B) mRNA, and the ability of NPR-B to generate cGMP in the Spinifex Hopping mouse, Notomys alexis. This rodent is a native of central and western Australia that is well adapted to survive in arid environments. Initially, CNP and NPR-B cDNAs (partial for NPR-B) were cloned and sequenced, and were shown to have high homology with those of rat and mouse. RT-PCR analysis showed CNP mRNA expression in the kidney, proximal and distal colon and small intestine, whilst NPR-B mRNA expression was found in the kidney, proximal and distal colon and the atria. Using a semi-quantitative multiplex PCR technique, the expression of renal CNP and NPR-B mRNA was determined in 7- and 14-day water-deprived hopping mice, in parallel with control hopping mice (access to water). Water deprivation significantly decreased the relative levels of CNP and NPR-B mRNA expression in both the 7- and 14-day water-deprived hopping mice, when compared to control hopping mice. In contrast, the ability of CNP to stimulate cGMP production was significantly increased after 14 days of water deprivation. This study shows that alterations in the renal CNP/NPR-B system may be an important physiological adjustment when water is scarce.

Expanding criminal sanctions for corporate crimes-deprivation of right to work and cancellation of education qualifications

Fines are the standard sanctions employed by most Western countries when a corporation has been convicted of a crime. However, some offences committed by corporations are too serious to be dealt with by way of a fine. There is a need to consider other sanctions that can be invoked in order to deter corporate crime. In this article, it is suggested that the focus should be on criminal sanctions against the natural persons who can potentially commit crimes on behalf of a corporation. New sentencing options against those who can potentially commit crimes on behalf of a corporation should include the annulment or suspension of an offender's academic  qualifications and the making of orders preventing an offender from working or being enrolled in an educational or vocational pursuit.

Regulation of selenoprotein SelS by glucose deprivation and endoplasmic reticulum stress - SelS is a novel glucose-regulated protein

SelS is a newly identified selenoprotein and its gene expression is up-regulated in the liver of Psammomys obesus after fasting. We have examined whether SelS is regulated by glucose deprivation and endoplasmic reticulum (ER) stress in HepG2 cells. Glucose deprivation and the ER stress inducers tunicamycin and thapsigargin increased SelS gene expression and protein content several-fold in parallel with glucose-regulated protein 78. The overexpression of SelS increased Min6 cell resistance to oxidative stress-induced toxicity. These results indicate that SelS is a novel member of the glucose-regulated protein family and its function is related to the regulation of cellular redox balance.

The effect of water deprivation on signalling molecules that utilise cGMP in the Spinifex Hopping Mouse Notomys alexis

In mammals the natriuretic and guanylin peptides influence renal and intestinal fluid content and electrolyte transport by binding to and activating guanylyl cyclase (GC) receptors that in turn stimulate production of the intracellular second messenger guanosine 3':5'-cyclic monophospate
(cGMP). However, the role of natriuretic and guanylin peptides in desert mammals is not understood. The spinifex hopping-mouse (Notomys alexis), has a suite of behavioural and physiological mechanisms that permits survival for extended periods without access to free water. Because signalling molecules that generate cGMP are known to promote water excretion, it was predicted that natriuretic and guanylin peptide synthesis would be down regulated in water-deprived N. alexis, and thus reduce the amount of water lost in the urine and faeces. However, in the kidney ANP and GC-A mRNA levels were increased in water-deprived mice, but CNP and GC-B mRNA levels were decreased. Water deprivation increased guanylin and uroguanylin mRNA expression in the distal colon, but it remained unchanged in the kidney and proximal colon. The expression of GC-C mRNA increased in the proximal colon but not in the distal colon. This study shows that water deprivation differentially affects the expression of regulatory molecules that stimulate cGMP producti
