Specific psychological interventions could be devised for mothers at risk for short and long-term PTSS just after the diagnosis.

The aim of this study consists in the measurement of psychological health and adaptation in mothers of children during the first 12 months of treatment for leukaemia and in the identification of possible early predictors. Ninety-four mothers were followed longitudinally at one week (T1), one month (T2), six months (T3) and 12 months (T4) post-diagnosis. The instruments used were: PTSD symptom checklist, BSI-18, Problem Scale, Ladder of life and an in-depth interview (EFI-C). Couple connectedness, family routine reorganisation, parental communication around the child's illness and trust in the medical care significantly increased from T1 to T4. Two models are proposed concerning possible predictors of mothers' PTSS at T2 and at T3. Clinical suggestions are proposed on the basis of our empirical findings in order to plan informative, clinical and practical interventions for mothers of children under treatment for leukaemia.

The present study aimed to evaluate the partial pressure of arterial blood gases in breath-hold divers performing a submersion at 40 m. Eight breath-hold divers were enrolled for the trials held at “Y-40 THE DEEP JOY” pool (Montegrotto Terme, Padova, Italy). Prior to submersion, an arterial cannula in the radial artery of the non-dominant limb was positioned. All divers performed a sled-assisted breath-hold dive to 40 m. Three blood samplings occurred: at 10 min prior to submersion, at 40 m depth, and within 2 min after diver’s surfacing and after resuming normal ventilation. Blood samples were analyzed immediately on site. Six subjects completed the experiment, without diving-related problems. The theoretically predicted hyperoxia at the bottom was observed in 4 divers out of 6, while the other 2 experienced a reduction in the partial pressure of oxygen (paO2) at the bottom. There were no significant increases in arterial partial pressure of carbon dioxide (paCO2) at the end of descent in 4 of 6 divers, while in 2 divers paCO2 decreased. Arterial mean pH and mean bicarbonate (HCO3−) levels exhibited minor changes. There was a statistically significant increase in mean arterial lactate level after the exercise. Ours was the first attempt to verify real changes in blood gases at a depth of 40 m during a breath-hold descent in free-divers. We demonstrated that, at depth, relative hypoxemia can occur, presumably caused by lung compression. Also, hypercapnia exists at depth, to a lesser degree than would be expected from calculations, presumably because of pre-dive hyperventilation and carbon dioxide distribution in blood and tissues.
