AbstractInfant-directed speech (IDS) is a specific register that adults use to address infants, and it is characterised by prosodic exaggeration and lexical and syntactic simplification. Several authors have underlined that this simplified speech becomes more complex according to the infant's age. However, there is a lack of studies on lexical and syntactic modifications in Italian IDS during the first year of an infant's life. In the present study, 80 mother–infant dyads were longitudinally observed at 3, 6, 9, and 12 months during free-play interactions. Maternal vocal productions were subsequently coded. The results show an overall low lexical variability and syntactic complexity that identify speech to infants as a simplified register; however, the high occurrence of complex items and well-structured utterances suggests that IDS is not simple speech. Moreover, maternal IDS becomes more complex over time, but not linearly, with a maximum simplification in the second half of the first year.

The authors adopt a person-centered approach to the investigation of the dimensionality of the union commitment construct by capitalizing on a 10-year longitudinal study (from 1992 to 2002) of 637 union members in their first year of employment measured again 1 and 10 years later. Results reveal four distinct profiles of union commitment, presenting a stable structure over time. These profiles demonstrate consistency in commitment level across the three most common union commitment dimensions, thus questioning the necessity of adopting a multidimensional approach. Results show that union members became more similar to other members of their profiles over time, and that their union commitment became slightly less extreme as union tenure increased. Finally, results show that union commitment profiles predict union participation, in accordance with our expectations, and suggest that endorsing positive attitudes toward unions and their instrumentality was a stronger predictor of profile membership than was satisfaction with the actions of one’s own union.

Abstract Background Bariatric surgery is the most effective treatment for obesity. During long-term follow-up, weight loss (WL) is variable between subjects. The aim of this study is to assess the change in percentage of total weight loss (%TWL) and excess weight loss (%EWL) and to describe the factors associated with greater or lesser WL over time. Methods Longitudinal study including patients treated with laparoscopic Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (LSG) and followed at Hospital Universitario San Ignacio, Bogotá (Colombia). Baseline data was recorded before surgery. Follow-up was performed at 3 (n=192), 6 (n=190), 9 (n=188), 12 (n=186), 24 (n=99) and 36 (n=30) months. Generalized Estimating Equation (GEE) analysis was used to assess the change in %TWL and %EWL over time. Results 196 patients were included (82.4% female, BMI 41.3±5.2 kg/m2). The tendency to increase on %TWL (31.6±6.6) and %EWL (80.2 RIQ 70.7-97.3) was evident in the first year, stabilizing after that. Nutritionist follow-up, baseline BMI>40 kg/m2 and WL≥10kg before surgery were associated with an average higher increase of %TWL (2.39% p=0.014, 0.41% p<0.001 and 0.37% p=0.003, respectively). Subjects who performed physical activity >30 minutes/day after surgery reduced %TWL in 0.74% (p=0.009). Similar findings were described on %EWL. Conclusion Follow-up during the first year after bariatric surgery is critical to achieving %TWL and %EWL goals. This study suggests that modifiable factors such as nutritional follow-up, WL before surgery and time of physical activity are associated with a significant change in %TWL and %EWL during follow-up by a multidisciplinary team.

This study examined relationships among utterance length, syntactic complexity, and stuttering in children's conversational speech. Analyses extended prior research by examining several different aspects of syntactic complexity, including sentence structure, clause structure, and phrase structure. Subjects were 12 boys who stutter, age 40 to 66 months, who produced 75-utterance conversational speech samples during free-play interactions with their mothers. Group analyses revealed significant differences between fluent and stuttered utterances in terms of all measures of utterance length and several measures of syntactic complexity. Analysis of the relationships between utterance length and syntactic complexity identified several measures of syntactic complexity that influenced stuttering and were independent of utterance length. Logistic regression analyses revealed that utterance length was better than syntactic complexity at predicting whether stuttering would occur, though neither utterance length nor syntactic complexity was a particularly strong predictor for individual subjects' data. Thus, findings suggest that utterance length and syntactic complexity cannot, by themselves, adequately account for the occurrence of stuttering in children's conversational utterances.

Objective To investigate if intraperitoneal and systemic interleukin-6 (IL-6) and soluble IL-6 receptor (sIL-6R) are related to each other and to peritoneal solute transport rate (PSTR). Design Longitudinal study in retrospectively selected patients. Setting Peritoneal dialysis (PD) unit of a university-based hospital. Patients and Methods 31 PD patients on treatment with conventional glucose-based solutions participated in a longitudinal study. IL-6 and sIL-6R were measured in plasma and overnight effluent, both at baseline and after 12 ± 2 months on PD. C-reactive protein (CRP) and serum albumin were used as surrogate markers of inflammation. PSTR of small solutes was evaluated using the dialysate-to-plasma ratio (D/P) of creatinine after a 4-hour dwell; PSTR of large solutes was evaluated using the 24-hour D/P ratio of albumin. Results D/P creat increased over time (0.67 ± 0.15 vs 0.80 ± 0.11, p < 0.0001) and correlated to D/P albumin only at the baseline evaluation. Patients with plasma IL-6 ≥median had higher ( p < 0.005) D/P creat at baseline [0.74 (0.62 – 0.87)] compared to patients with IL-6 < median [0.57 (0.47 – 0.66)]. Dialysate IL-6 at baseline was also higher ( p < 0.05) in patients with plasma IL-6 ≥median [24.7 (16.5 – 38.5) pg/mL] compared to patients with IL-6 < median [14.1 (10 – 25.7) pg/mL]. Neither CRP nor albumin changed over time on PD, although they were closely linked to plasma IL-6 levels. A strong positive correlation was found between D/P creat and dialysate IL-6 (rho = 0.77, p < 0.0001) at baseline, but not at 1 year. In contrast, there was a significant correlation between D/P creat and dialysate sIL-6R (rho = 0.39, p < 0.05) at 1 year, but not at baseline. At 1 year, 17 patients with increasing PSTR had higher increases in dialysate IL-6 (28 ± 26 vs –21 ± 78 pg/mL, p < 0.05) and levels of dialysate sIL-6R (693 ± 392 vs 394 ± 274 pg/mL, p = 0.05) compared to patients with stable PSTR ( n = 11). Patients who had peritonitis presented higher baseline serum IL-6 concentration (6.8 ± 1.0 pg/mL) compared with patients without peritonitis (4.0 ± 0.6 pg/mL, p < 0.05). Finally, both at baseline and after 1 year, there were significant correlations between plasma and dialysate IL-6 (rho = 0.46, p < 0.05, and rho = 0.40, p < 0.05) respectively. Conclusions These findings indicate that, ( 1 ) intraperitoneal and systemic inflammation increase in PD patients during the first year of therapy; ( 2 ) intraperitoneal and systemic inflammation may be interrelated and the IL-6 system may be the link; ( 3 ) the IL-6 system (both intraperitoneal and systemic) is associated with PSTR, particularly in the early phase of PD treatment, in which small and large solute transport are linked. Signs of a transition between acute and chronic inflammation were observed in the follow-up evaluation. Inflammation may, at least in part, be responsible for the development of a high PSTR, and this could be one reason for the high mortality in patients with high PSTR.

Abstract Optimizing dyadic health is a central goal of dyadic frameworks. Yet, research has focused on interdependent individual health or the transactional nature of health within dyads. Emerging research has explored dyadic health through the lens of congruence and balance. This longitudinal study examined dyadic mental health in 76 couples (M = 67.88 ± 11.54) during the first year of lung cancer. As expected, multilevel modeling found mental and physical health of couples were significantly associated at baseline (p &lt; .05). Congruence in mental health was significantly associated with changes in physical health over time for survivors (p &lt; .05) but not partners, whereas balanced mental health had differential effects on the physical health of survivors and partners (p &lt; .01). Discussion will focus on the implications of congruent versus balanced dyadic health for the couple, evaluation of interventions, and propose ways to define optimal dyadic health.

This longitudinal study including 87 infant–mother dyads examined the relation between infant temperamental attention, maternal encouragement of attention, language, and the effects of gender. At ages 0;4, 0;8, and 1;0, global attention was assessed from Rothbart's (1981) IBQ; manipulative exploration was assessed with the Bayley (1969) IBR; and maternal verbal, visual and physical encouragement of attention were coded from 5 minutes of mother–infant free-play. At 1;0, language was measured using language items from the Bayley Mental Scale and parent-report items from Hendrick, Prather & Tobin's (1984) SICD-Revised. Multiple regressions indicated that gender, infants’ manipulative exploration and maternal physical encouragement of attention at 0;4, and maternal verbal encouragement of attention at 1;0, were all positively related to language at 1;0. Interactions indicated that girls high in 0;8 or 1;0 manipulative exploration had more advanced language skills than girls low in manipulative exploration or than boys, regardless of their attention level. Additionally, maternal verbal encouragement of attention appears to be particularly salient in the development of language for boys.

In a longitudinal study, 17 parent–child dyads were observed during free-play when the children were 1;0, 1;6, and 2;0. Parents' labelling input in the verbal and gestural modalities was coded at each session, and parents completed a vocabulary checklist for their children at each visit. We analysed how the frequency of labelling in the verbal and gestural modalities changed across observation points and how changes in parental input related to children's vocabulary development. As a group, parents' verbal labelling remained constant across sessions, but gestural labelling declined at 2;0. However, there are notable individual differences in parental trajectories in both modalities. Parents whose verbal labelling frequency increased over time had children whose vocabulary grew more slowly than those whose labelling frequency decreased, remained constant, or peaked at 1;6. There were few systematic relations between patterns of parental gesturing and children's vocabulary development. Parents' verbal and gestural labelling patterns also appeared dissociable. However, parents' words and gestures were correlated when their children were 1;6, suggesting that gestures serve an important bootstrapping function at a critical point in children's vocabulary development.
