Background: The Atherogenic Index of Plasma is a predictive biomarker of atherosclerosis in adults but there is a lack of studies in paediatric population aimed at evaluating the longitudinal changes of the AIP and of the cardiometabolic blood profile related to nutritional interventions. The aim of this study was to compare the effect of individual- versus collective-based nutritional-lifestyle intervention on the Atherogenic Index of Plasma in schoolchildren with obesity. Methods: One-hundred sixty-four children aged 6–12 years with Body Mass Index z-score > 2 referred to the Paediatric Obesity Clinic, San Paolo Hospital, Milan, Italy, were consecutively enrolled and randomized to undergo to either an individual- (n = 82) or a collective- (n = 82) based intervention promoting a balanced normo-caloric diet and physical activity. In addition, the individual intervention included a tailored personalized nutritional advice and education based on the revised Coventry, Aberdeen, and London-Refined taxonomy. Both at baseline and after 12 months of intervention, dietary habits and anthropometric measures were assessed, a fasting blood sample were taken for biochemistry analysis. Results: The participation rate at 12 months was 93.3% (n = 153 patients), 76 children in the individual-intervention and 77 children in the collective intervention. At univariate analysis, mean longitudinal change in Atherogenic Index of Plasma was greater in the individual than collective intervention (− 0.12 vs. − 0.05), as well as change in triglyceride-glucose index (− 0.22 vs. − 0.08) and Body Mass Index z-score (− 0.59 vs. − 0.37). At multiple analysis, only change in Body Mass Index z-score remained independently associated with intervention (odds ratio 3.37). Conclusion: In children with obesity, an individual-based nutritional and lifestyle intervention, including techniques from the CALO-RE taxonomy, could have an additional beneficial effect over a collective-based intervention, although the actual size of the effect remains to be clarified.

The article discusses a quantitative study of the Ospedalizzazione Domiciliare Cure Palliative Oncologiche program in Lombardy, Italy. The study used a descriptive analysis from an institutional database of regional expenditure, service characteristics, and outcomes during 2009-2011. Results showed that the program uncovered three strenghts such as quantity of home visits, enrollment of eligible patients, and prompt identification, as well as two weaknesses.

Abstract: To evaluate the long-lasting immunogenicity and reactogenicity of a virosomal influenza vaccine in subjects with type I diabetes, a trial was conducted during the 2007–2008 influenza season in Milan, Northern Italy. One hundred five subjects aged 9–30 years were randomized to receive by intramuscular injection vaccination by a single dose (0.5ml) of either a virosomal (Inflexal V®) (n =52) or a standard subunit (Influvac®) (n =53) vaccine. Serum hemagglutinin inhibition antibody titres were determined against the three recommended influenza-like strains, A/H1N1, A/H3N2 and B, at pre-vaccination, and 1 and 6 months post-vaccination. Geometric mean titres were increased in the two groups 1 and 6 months post-vaccination (P <0.001). One month post-vaccination both vaccines met the CPMP requirement for immunogenicity with high seroprotection rates (>95%) for strains A/H1N1 and A/H3N2, and a seroprotection of 73% and 70% in the virosomal and subunit vaccine for strain B. Mean fold increase ranged 2.8 (A/H3N2)–6.2 (A/H1N1) in the virosomal group and 2.3 (A/H3N2)–4.8 (A/H1N1) in the subunit group. Immunogenicity declined 6 months post-vaccination in both groups, and the CPMP requirement for immunogenicity was satisfied only in the virosomal group. In subjects without pre-existing antibodies to strain B (titre <10), the virosomal vaccine showed higher immune response than the subunit vaccine 6 months post-vaccination, with a geometric mean titre (95% CI) of 40.2 (30.7–54.6) vs. 21.2 (14.6–30.8). Reactogenicity was similar in the two vaccines. All reactions were transient and not severe. The results indicate that in older children and young adults with type I diabetes influenza vaccination with a virosomal or a standard subunit vaccine is safe and adequately immunogenic against the three influenza vaccine strains. In addition, the virosomal vaccine may show better long-lasting immune response than the standard subunit vaccine, especially in subjects without pre-existing antibodies to influenza strains.

Abstract: We evaluated the pharmacological activity of whole-blood serum from atorvastatin- vs. simvastatin- (both 40mg/day) treated hypercholesterolemic patients (n =10) on cultured smooth muscle cell (SMC) proliferation and cholesterol biosynthesis, as related to lipid-lowering effect. Patients received either single or 2-weeks repeated doses of both simvastatin and atorvastatin, following a randomised, double-blind, cross-over design. Blood samples were collected before drug administration and at the scheduled intervals after administration, and the obtained serum was separated by centrifugation, sterilized and frozen until assayed. Cultured SMC were supplemented with medium plus 15% of separate serum sampled from the patients, and grown for 72h. Proliferation was assayed by a Coulter Counter, while cholesterol biosynthesis was measured by the incorporation of 14C-acetate into cholesterol, under the same experimental conditions. Atorvastatin was more active vs. simvastatin in reducing total- (−28.3% vs. −20.7%; p =0.045) and LDL-cholesterol (−39.8% vs. −30.1%; p =0.011) after a 2-weeks regimen. Serum from atorvastatin-treated patients inhibited SMC proliferation vs. t =0 after both single (AUC −21.6%) and repeated (AUC −26.9%) doses, while serum from simvastatin-treated patients inhibited SMC proliferation only after repeated doses (AUC −24.5%). Interestingly, in the same experimental conditions, the serum concentrations of both statins (and of their active metabolites) were constantly below the detection limits, as shown from the lack of inhibition of cholesterol biosynthesis. The absence of any significant association between the lipid-lowering effects and the inhibition of SMC proliferation, together with no detectable active statin in the serum, suggests that these effects are elicited through independent mechanisms.

Abstract: To evaluate long-term immunogenicity of a virosomal subunit inactivated influenza vaccine in children with asthma, a prospective study was conducted during 2005–2006 influenza season in six public pediatric clinics in Milan and surroundings, Northern Italy. A single dose (0.5ml) of a virosomal subunit inactivated influenza vaccine (Inflexal V®) was injected in 106 asthmatic children aged 3–9 years. Serum hemagglutinin inhibition antibody titers were determined against the recommended influenza strains A/New Caledonia (H1N1), A/California (H3N2), and B/Shanghai (B), at pre-vaccination and 1 and 6 months after vaccination. Seroconversion rate (95% CI) against the strains A/H1N1, A/H3N2 and B was, respectively, 78% (68.6–85.7), 57% (46.7–66.9) and 66% (55.8–71.2) at 1 month. Seroprotection (titer≥40) rate for A/H1N1, A/H3N2 and B was, respectively, 87% (77.8–92.2), 82% (72.6–89.7) and 90% (82.6–94.8) at 1 month and 74% (64.3–82.3), 77% (67.5–84.8), and 77% (67.5–84.8) at 6 months. Seroprotection rate was high and persistent (>95%) in children with pre-existing antibodies (titer≥10) at pre-vaccination for any specific strain. In children without pre-existing antibodies, seroprotection rate for A/H1N1, A/H3N2 and B was, respectively, 67.6%, 66.7% and 74.4% at 1 month, and 35.1%, 56.2% and 41.0% at 6 months after vaccination. Vaccine was well tolerated. These results indicate that in unvaccinated children with asthma vaccination with a single dose of virosomal-adjuvanted influenza vaccine is well tolerated and effective as a whole. However, while immunity response and persistence are excellently high in children with pre-existing antibodies, in children naive for the antigens the immune parameters are lower at 6 months after vaccination.

The timely administration of the effective therapy is an important factor for the favourable outcome of patients with sepsis. In this study, we evaluated a new rapid antimicrobial susceptibility testing (AST) method, the Vitek®Reveal ™ system, to determine the antibiotic susceptibility of 44 Gram-negative bacteria randomly isolated from blood. The results show a mean turnaround time of 5.42 h. The overall agreement with the reference method was >90%, except for piperacillin/tazobactam and cefepime (90.4%). The study, therefore, suggests that the assay decreases the time for obtaining AST with the potential to have a positive impact on patient care. However, further studies are needed to extend and confirm these preliminary findings, particularly the assay performance for some drugs and eventually for Gram-positive micro-organisms.

Background: Given their sensitivity to environmental alterations, odonates act as reliable bioindicators to assess the effects of changes in freshwater ecosystems and associated terrestrial habitats. The region comprised between Lario and Brianza (Provinces of Como, Lecco and Monza and Brianza - Lombardy, N Italy) is one of the most urbanised of the Italian peninsula and large parts of its territory have been heavily altered, especially at low elevation. Despite this pervasive anthropogenisation, the area is still characterised by a considerable variety of freshwater habitats, possibly harbouring rich odonate communities, which, however, have been never thoroughly investigated. This study aimed to produce the first commented checklist of the Odonata of this region, accompanied by distribution maps., New Information: The work is based on 12,093 records spanning from 1981 and 2022, derived from literature (289), revision of collections (42), citizen-science projects (1249) and unpublished data from the authors and their collaborators (10,513). Overall, fifty-five species occur - or occurred in the past - in the study area (20 Zygoptera and 35 Anisoptera). One species, Erythrommanajas , was confirmed exclusively before 1978, while seven species ( Lestesbarbarus , Coenagrionscitulum , Aeshnaaffinis , Anaxephippiger , Somatochloraarctica , Sympetrummeridionale and Trithemisannulata ) have been recorded only after 2000. Records referring to Chalcolestesparvidens and Sympetrumflaveolum were considered questionable and excluded from the checklist. A list of species for each protected site is additionally provided. This work highlighted the importance for odonates of Lario and Brianza Regions from a national perspective, in particular for species of conservation priority/interest, such as Sympecmapaedisca , Oxygastracurtisii and Sympetrumdepressiusculum ., (Gaia Bazzi, Andrea Galimberti, Claudio Foglini, Luciano Bani, Lionello Bazzi, Piero Bonvicini, Roberto Brembilla, Massimo Brigo, Alberto Cavenaghi, Giuseppe Colombo, Cesare Della Pietà, Carlo Galliani, Ettore Guarnaroli, Nicola Larroux, Alessandro Monti, Valerio Orioli, Francesco Ornaghi, Nicola Pilon, Giuliana Pirotta, Giovanni Radaelli, Giulia Tessa, Giacomo Assandri.)

Objectives and Study: Salicylic acid (SA), a phenolic compound produced by plants, may play a beneficial role on health. A pilot study showed that children with obesity had lower serum SA than normal-weight children. The aim of this trial was to evaluate the effect of a 1-year nutritional-behavioral intervention on serum SA levels and to study a possible association between SA levels and metabolic profile changes in children with obesity., Methods: This was an interventional longitudinal observational uncontrolled cohort study. Forty-nine children with obesity, aged >6 years were evaluated. BMI (body mass index) z-scores were calculated. Fasting blood samples were analyzed for lipids, insulin, and glucose. The most significant metabolic variables were calculated. Serum SA was measured using a gas chromatography-mass spectrometry method. The 1-year intervention was based on the promotion of a balanced and normocaloric diet, in accordance with the national guidelines for treatment of childhood obesity. Additionally, behavioral education, based on the revised CALO-RE (Coventry, Aberdeen, and London-REfined) taxonomy, was performed., Results: At the end of intervention, children showed an increase in serum SA levels (mean (Standard Deviation, SD) 0.06 (0.02) vs. 0.09 (0.05) µmol/L; p < 0.001), a reduction of BMI z-score (3.14 (0.79) vs. 3.02 (0.82); p < 0.001), TyG index (4.52 (0.20) vs. 4.48 (0.23); p < 0.001), AIP (atherogenic index of plasma) (0.36 (0.21) vs. 0.27 (0.25); p < 0.001), and triglycerides/HDL (high density lipoprotein) cholesterol (2.57 (1.28) vs. 2.18 (1.22); p < 0.001) ratio. No statistically significant change in HOMA-IR (homeostasis model assessment index) was observed (4.20 (3.29) vs. 4.03 (2.28)). An association between the longitudinal variation of serum SA and HOMA-IR was found (correlation coefficient: -0.338, p = 0.02)., Conclusion: Nutritional-behavioral intervention may improve the circulating SA and the metabolic profile in children with obesity. Serum SA could influence mainly glucose metabolism. Further larger studies are needed to evaluate whether a nutritional intervention based on specific advice regarding the quantity and type of fruit and vegetables (FV) consumption could provide benefits in terms of metabolic syndrome.

Introduction: Wheezing is the most common symptom associated with asthma in young children. There is a lack of well-designed prospective studies on the relationship of exclusive breastfeeding with wheezing in infants. This prospective cohort study investigated whether a relationship exists of exclusive breastfeeding with wheezing at 12 months of age., Materials and Methods: A series of 1632 mother-infant pairs were sequentially recruited. Mothers were trained at hospital on breastfeeding practices and how to recognise wheezing. At hospital discharge they received a calendar-diary to record the date at stopping breastfeeding and at onset of wheezing. Data were collected by telephone interviews through 12 months post-delivery. Breastfeeding was in accordance with the World Health Organisation and wheezing with the International Classification of Diseases (ICD-10-CM code R06.2)., Results: At 12 months 1522 mother-infant pairs were participating. Breastfeeding started in 95.9% of them and was exclusive in 86.1%. The incidence of wheezing ever and recurrent wheezing at 12 months of age was 33.7% and 10.0%, respectively. Duration of exclusive breastfeeding was shorter in wheezing than non-wheezing infants (median 2.6 months vs. 4.1 months, P<0.001). After adjustment for confounders each month of exclusive breastfeeding reduced the risk of wheezing ever by 11% and of recurrent wheezing by 15%, at 12 months of age., Conclusion: Longer duration of exclusive breastfeeding reduces the risk of wheezing throughout the first 12 months of life. These findings would be relevant to all healthcare operators and mothers, also to improve their awareness about the best feeding practices for the infant's health., (Copyright © 2016 SEICAP.

Patients are increasingly encouraged to become active players in self-care and shared decision-making. Such attention has led to an explosion of terms - empowerment, engagement, enablement, participation, involvement, activation - each having multiple and overlapping meanings. The resulting ambiguity inhibits an effective use of existing evidence. This study addresses this problem by delivering an evidence-based concept mapping of these terms that delineates their boundaries and mutual relationships. We implemented a literature review of contributions associated to patient empowerment, activation, engagement, enablement, involvement, and participation. We implemented a keyword-based strategy collecting contributions published in PubMed database in the 1990-2013 timespan. A total of 286 articles were selected. The results identified three distinct interpretation of patient empowerment, either conceived as a process, an emergent state or as a participative behaviour. Most definitions recognize empowerment as the combination of ability, motivation and power opportunities. A concept mapping for patient empowerment, activation, enablement, engagement, involvement, and participation was then delineated. The concept map consists of two dimensions (nature and focus of concept) and marks distinctions and relationships between the concepts. The resulting concept map paves the way for a number of future research directions that can help improve our understanding of the antecedents and consequences of patient empowerment policies., (Copyright © 2014 Elsevier Ireland Ltd.

Aim: To assess a relationship between longitudinal changes in liver fat content and biochemical parameters in obese children after 1-year nutritional intervention., Methods: Forty-six obese children, 21 males and 25 females, aged 6-14 years, underwent metabolic measurements, liver ultrasonography (US) and chemical-shift magnetic resonance imaging (MRI) examinations at baseline and after 1-year nutritional intervention. A child was defined obese if her/his body mass index (BMI) was above the age- and sex-adjusted BMI Cole's curve passing through the cut-off of 30 kg/m(2) at 18 years. BMI Z scores were calculated and adjusted for age and gender by using the Cole's LMS-method and Italian reference data. Biochemistry included serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Abdominal US and chemical-shift MRI were performed according to a randomized sequence. The same radiologist performed US by a GE Logiq 9 (General Electric Healthcare Medical Systems, Milwaukee, WI, United States) using a 3.5-MHz convex array transducer. Liver echogenicity was evaluated independently on videotape by 3 radiologists unaware of the child and MRI outcomes, and a consensus was established. Another experienced radiologist, unaware of the child and US data, performed the abdominal chemical-shift MRI with a 1-t system NT-Intera (Philips Medical Systems, Best, The Netherlands) and a phased-array coil. Liver fat fraction (FF) on MRI was judged elevated when greater than 9%. A FF > 18% was considered expressing more severe cases of fatty liver according to Fishbein. A nutritional-behavioral intervention was recommended to promote a normocaloric balanced diet and active lifestyle based on the Italian guidelines for treatment of childhood obesity., Results: Compared to baseline, at the end of intervention children showed lower intakes of energy (mean ± SD: 2549 ± 1238 Kcal vs 1770 ± 622 Kcal, P < 0.0001), total fat (90 ± 47 g vs 52 ± 23 g, P < 0.0001), carbohydrates (356 ± 174 g vs 241 ± 111 g, P = 0.001), and protein (99 ± 48 g vs 75 ± 23 g, P = 0.006) intakes. Prevalence of FF ≥ 9% declined from 34.8% to 8.7% (P < 0.01), with a mean reduction of 7.8% (95%CI: 5.0-10.6). At baseline, FF was associated with liver biochemical parameters (maximum P < 0.001). At the end of the intervention association was found with AST (P = 0.017). Change of FF was associated with change in AST (P = 0.027) and ALT (P = 0.024). Rate of increased liver echogenicity declined from 45.6% to 21.7% (P < 0.0001). Liver echogenicity was associated with ALT at baseline only (P < 0.001). An age- and sex- adjusted multiple regression analysis showed that FF change was independently associated with change in serum AST (adjusted regression coefficient 0.348, P = 0.048)., Conclusion: The results suggest that in obese children longitudinal changes in liver fat content based on MRI may be associated with change in serum transaminases suggesting novelty in monitoring nonalcoholic fatty liver disease.

Aim:   The aim of this study was to examine attitudes and practices of family paediatricians in Italy towards infant feeding., Methods:   A questionnaire was sent to 850 paediatricians across Italy, asking about attitudes and practices towards infant feeding with focus on the World Health Organization's criteria., Results:   The response rate was 91.2%. Breastfeeding is recommended for 6-11 months (70.6%) or longer (29.4%). A 95% of paediatricians recommend introducing complementary foods throughout 4-5.9 months. Among paediatricians who give indications about the minimum acceptable diet (61.7%), recommendations agree with WHO in 71.3% and 83.3% of cases for infants aged 6-8 or 9-11 months, respectively. A 95.6% of paediatricians recommend consumption of meat for infants aged 6 months or more, and 98.4% use of formula milk for infants having breastfeeding stopped in the first year of life. Paediatricians reported own experience (73.4%) and reading (54.2%) as main sources of information. A 70% of paediatricians know the WHO/Infant and Young Child Feeding Practices criteria regarding breastfeeding but <5% the complementary feeding indicators., Conclusion:   Family paediatricians in Italy have positive disposition towards infant feeding but their knowledge and practices are suboptimal with respect to the WHO criteria, especially regarding complementary feeding., (© 2012 The Author(s)/Acta Paediatrica © 2012 Foundation Acta Paediatrica.)

Introduction: The aim of the present study was to examine whether hyperphenylalaninemic children on unrestricted diet (MHP) may exhibit a different LCPUFA profile from PKU or healthy children in plasma phospholipids., Patients and Methods: Forty-five MHP children (age 9-14 years) were age and sex matched with 45 PKU and 45 healthy children. Fatty acids were determined and expressed as % of total fatty acids., Results: MHP children showed docosahexaenoic acid (DHA) levels higher than PKU children (mean difference, 0.2%; 95% confidence interval, 0.02%-0.38%), although difference was not significant after correction for multiple comparisons, and lower levels than healthy children (-0.8%; -1.01% to -0.59%). Concentration of n-3 PUFA was higher in MHP than PKU children (0.6%; 0.4% to 0.8%),, Conclusions: The results suggest that low DHA levels in plasma phospholipids not only are evident in PKU but also may occur in MHP children, who are on unrestricted diet, as compared to healthy children., (Copyright © 2010 Elsevier Ltd.

Background: Docosahexaenoic acid (DHA) intake throughout the first year of life is associated with neurodevelopmental and neuropsychological benefits. Few studies have evaluated the role of DHA intakes on age at achievement of gross motor milestones., Objective: The objective was to assess the effects of DHA supplementation throughout the first year of life on the achievement of four gross motor milestones in healthy infants., Design: In this multicenter prospective, randomized, double-blind, placebo-controlled trial, 1160 healthy neonates were assigned to receive supplementation with either 20 mg liquid DHA (n = 580) or placebo (n = 580) orally once daily throughout the first year of life. The primary endpoint was the time at achievement of 4 gross motor milestones (sitting without support, hands-and-knees crawling, standing alone, and walking alone). All analyses were performed on an intention-to-treat basis., Results: The time to achievement of sitting without support was shorter (P < 0.001) in infants who received DHA [median: 26 wk; interquartile range (IQR): 24-29 wk] than in those who received placebo (27 wk; 26-31 wk). No significant difference between infants who received DHA or placebo was found for hands-and-knees crawling [39 wk (34-44 wk) compared with 40 wk (35-44 wk), respectively], standing alone [49 wk (43-55 wk) compared with 49 wk (44-57 wk), respectively], and walking alone [55 wk (50-60 wk) compared with 56 wk (52-61 wk), respectively]., Conclusions: Despite the 1-wk advance in sitting without support associated with DHA supplementation, no demonstrable persistent effects of DHA supplementation on later motor development milestones were found. Thus, the long-term clinical significance of the 1-wk change in sitting without support, if any, remains unknown. This trial is registered at (clinicaltrials.gov) as NCT00610922.

Pro12Ala variant of peroxisome-proliferator-activated receptor-gamma2 (PPAR-gamma2) may be linked to insulin sensitivity. This study examined whether an association of PPAR-gamma2 Pro12Ala with insulin resistance and plasma LCPUFAs may exist in obese children. One hundred and forty Italian normolipidemic obese children (58 girls and 82 boys, mean age [SD], 10.2 [2.7] y) entered the study. Obesity was defined according to International Obesity Task Force. BMI Z-scores were calculated. Fasting blood glucose, insulin, lipids and plasma fatty acids were measured. Insulin resistance was estimated by the homeostatic model assessment (HOMA-IR). The frequency of Ala allele was 9%. Mean [SD] values of fasting insulin and HOMA-IR in Pro/Pro versus Pro12Ala groups were: 19.3 [10.6] versus 14.1 [10.4] microU/mL (p = 0.017) and 4.2 [2.3] versus 3.0 [2.3] (p = 0.022). Mean [SD] values of plasma C20:3n-9 and of C20:4n-6, C20:5n-3, C22:6n-3 and n-6/n-3 LCPUFA in phospholipds in Pro/Pro versus Pro12Ala groups were: 0.15 [0.07] versus 0.12 [0.08] % (p = 0.014), 8.9 [1.9] versus 10.2 [2.6] % (p = 0.023), 0.34 [0.15] versus 0.42 [0.11] % (p = 0.005), 2.1 [0.9] versus 2.6 [0.9] % (p = 0.032) and 4.8 [1.2] versus 4.2 [0.7] (p = 0.017). Pro12Ala may be associated with higher insulin sensitivity and higher LCPUFAs, particularly n-3, levels in plasma phosholipids of obese children.

Purpose: This study was designed to compare the efficacy of two different "chemical sphincterotomies" for chronic anal fissure., Methods: From January to December 2001, 30 consecutive patients (17 males; mean age, 41.8 years) with chronic posterior anal fissure were enrolled. The patients were randomly assigned to receive 0.2 percent glycerine trinitrate ointment applied three times daily at the anal margin for eight weeks (Group A) or 20 units Botulinum toxin A injection into the internal anal sphincter on each side of the anterior midline (Group B). The patients were reviewed at 15 days, 1, 3, 6, 12, and every other 12 months. Follow-up ranged between 36 and 46 months. Patients in either group who failed to improve were referred for surgical treatment., Results: Twelve patients in Group A and 11 in Group B had improvement or relief from symptoms at the first visit. The fissure was healed in ten patients in Group A and in eight in Group B within three months (66.7 and 57.1 percent). Recurrence of the fissure occurred in five patients in each group during the follow-up. The healing rate at three years was 40 and 33.3 percent for Group A and B, respectively. No patients in either group reported serious adverse effects; however, three patients in Group A (20 percent) had transient headache. None had fecal incontinence., Conclusion: Both treatments may be considered as first-line treatment even if less effective than surgery.

Purpose: The aim of this study was to define any benefits in terms of early outcome for laparoscopic colectomy in patients over 80 years old compared with open colectomy., Methods: Sixty-one patients undergoing laparoscopic colectomy for colorectal cancer were matched to 61 open colectomy patients for gender, age, year of surgery, site of cancer, and comorbidity on admission. Independence status on admission and at discharge from the hospital was also evaluated., Results: Mean (standard deviation) age was 82.3 (3.5) years in the laparoscopy group and 83.1 (3.3) years in the open group. Conversion rate was 6.1 percent. Operative time was 49 minutes longer in the laparoscopy group (P = 0.001). The overall mortality rate was 2.4 percent. The morbidity rate was 21.5 percent in the laparoscopy group and 31.1 percent in the open group (P = 0.30). Patients in the laparoscopy group had a faster recovery of bowel function (P = 0.01) and a significant reduction of the mean length of hospital stay (9.8 vs. 12.9 days for the open group, P = 0.001). Laparoscopy allowed a better preservation of postoperative independence status compared with the that of the open group (P = 0.02)., Conclusion: Laparoscopic colectomy for cancer in octogenarians is safe and beneficial including preservation of postoperative independence and a reduction of length of hospital stay.

Purpose: The aim of this study was to evaluate whether laparoscopic colorectal surgery can modify the risk factors for the occurrence of postoperative morbidity., Methods: A total of 384 consecutive patients with colorectal disease were randomized to laparoscopic resection (n = 190) or open resection (n = 194). On admission, demographics, comorbidity, and nutritional status were recorded. Operative variables, patient outcome, and length of stay were also recorded. Postoperative complications were registered by four members of staff not involved in the study., Results: The overall morbidity rate was 27.1 percent, with the rate in the laparoscopic group (18.7 percent) being less than that in the open group (31.5 percent; P = 0.003). Patients who underwent laparoscopic resection had a faster recovery of bowel function (P = 0.0001) and a shorter length of stay (P = 0.0001). In the whole cohort of patients, multivariate analysis identified open surgery (P = 0.003), duration of surgery (P = 0.01), and homologous blood transfusion (P = 0.01) as risk factors for postoperative morbidity. In the open group, blood loss (P = 0.01), homologous blood transfusion (P = 0.01), duration of surgery (P = 0.009), weight loss (P = 0.06), and age (P = 0.08) were related to postoperative morbidity. In the laparoscopic group the only risk factor identified was duration of surgery (P = 0.005)., Conclusion: In the laparoscopic group, both postoperative morbidity and length of stay were significantly reduced and most risk factors for postoperative morbidity disappeared.

Purpose: This study was designed to compare metabolic and functional results after laparoscopic and open colorectal resection., Methods: Seventy-nine patients were randomly assigned to laparoscopic (n = 40) or open (n = 39) colorectal resection. Before and after operation, the following parameters were determined: respiratory function (spirography and blood gas); serum level of cortisol, lactate, and C-reactive protein; total lymphocyte count; and CD4 and CD8 lymphocyte subsets. Intraoperative core temperature was measured by a bladder probe. Postoperative pain and analgesic consumption were also monitored., Results: Mild operative hypothermia, a trend to postoperative reduction of total lymphocyte count, and significant impairment of respiratory function early after surgery were found in both groups. Laparoscopy showed a higher CD4/CD8 ratio (P = 0.01) on postoperative Day 1 and a faster return of C-reactive protein to preoperative values (P = 0.01) than in the open colorectal resection group. Morphine consumption in the first 48 hours after surgery was lower in the laparoscopic than in the open group (P = 0.02)., Conclusions: Laparoscopy was associated with a less pronounced immunosuppression and inflammatory response and a lower consumption of analgesic drugs than open surgery. Moreover, our data did not show any additional detrimental effect of laparoscopy on either operative core temperature or early postoperative respiratory function.
