Executive summary: Evaluating the evidence base to support the inclusion of infants and children from birth to 24 mo of age in the Dietary Guidelines for Americans--"the B-24 Project".

The Dietary Guidelines for Americans (DGA) are the cornerstone of US government efforts to promote health and prevent disease through diet and nutrition. The DGA currently provides guidelines for ages ≥ 2 y. In an effort to determine the strength of the evidence to support the inclusion of infants and children from birth to age 24 mo, the partner agencies led by the Department of Health and Human Services Office of Disease Prevention and Health Promotion and the USDA Center for Nutrition Program and Policy initiated the project entitled "Evaluating the evidence base to support the inclusion of infants and children from birth to 24 months of age in the Dietary Guidelines for Americans--the B-24 Project. " This project represents the first step in the process of applying systematic reviews to the process of deciding whether the evidence is sufficient to include this age group in future editions of the DGA. This supplement includes the B-24 Executive Summary, which describes the B-24 Project and the deliberations of the 4 working groups during the process of developing priority topics for the systematic review, and a research agenda to address the critical gaps. Also included in this supplement issue is an article on the Nutrition Evidence Library methodology for developing systematic review questions and articles from the invited content presenters at the B-24 Prime meeting.
Altered cellular calcium regulatory systems in a rat model of cirrhotic cardiomyopathy.

BACKGROUND & AIMS Decreased cardiac contractility has been observed in cirrhosis, but the cause remains unclear. Because cardiomyocyte contraction depends on Ca2+ influx entering via L-type Ca2+ channels (I(Ca,L)s) to activate Ca2+ release from the sarcoplasmic reticulum, we postulated that the Ca2+ transients may be abnormal in cirrhotic cardiomyocytes. We aimed to investigate the status of the cellular Ca2+-regulatory system in a rat model of cirrhotic cardiomyopathy. METHODS Cirrhosis was induced by bile duct ligation. The I(Ca,L) protein expression was detected by Western blotting. Ca2+ currents were measured electrophysiologically. The intracellular Ca2+ system, which includes the ryanodine receptor 2 (RYR2), sarcoplasmic reticulum Ca2+-pump adenosine triphosphatase (SERCA2), and Ca2+-binding protein were quantitatively assayed by reverse-transcription polymerase chain reaction and Western blots and functionally by 3H-ryanodine binding and radiolabeled Ca2+ uptake. RESULTS I(Ca,L) protein expression was reduced in cirrhotic rats compared with controls, and the peak inward Ca2+ current was significantly less. At all membrane potentials examined, I(Ca,L)s current densities from cirrhotic animals were consistently lower, and the response to maximal isoproterenol stimulation was also significantly lower. Protein expression and messenger RNA transcription for RYR2, SERCA2, and calsequestrin were quantitatively unchanged, and 3H-ryanodine binding characteristics and Ca2+ uptake were also unaltered. CONCLUSIONS We conclude that the decreased cardiac contractility in cirrhotic cardiomyocytes is caused by dysfunction of the Ca2+-regulatory system. Plasma membrane I(Ca,L)s are quantitatively reduced and functionally depressed, whereas intracellular systems are intact.
Comparative and correlative assessments of cytokine, complement and antibody patterns in paediatric type 1 diabetes

One of the most widespread and effective environmental factors is the infection with enteroviruses (EVs) which accelerate β cell destruction in type 1 diabetes (T1D). This study represented a comparison between diabetic EV+ and EV– children as well as correlation analysis between autoantibodies, T1D markers, cytokines, complement activation products and anti‐coxsackievirus (CV) immunoglobulin (Ig)G. EV RNA was detected in Egyptian children with T1D (26·2%) and healthy controls (0%). Detection of anti‐CV IgG in T1D‐EV+ resulted in 64% positivity. Within T1D‐EV+, previously diagnosed (PD) showed 74 versus 56% in newly diagnosed (ND) children. Comparisons between populations showed increased levels of haemoglobin A1c (HbA1c), C‐reactive protein (CRP), nitric oxide (NO), glutamic acid decarboxylase and insulin and islet cell autoantibodies [glutamic acid decarboxylase autoantibodies (GADA), insulin autoantibodies (IAA) and islet cell cytoplasmic autoantibodies (ICA), respectively], interferon (IFN)‐γ, tumour necrosis factor (TNF)‐α, interleukin (IL)‐1β, IL −10, IL −12, IL −17, C3d and sC5–9 in T1D‐EV+ versus T1D‐EV–. Conversely, both IL‐20 and transforming growth factor (TGF‐β) decreased in T1D‐EV+ versus EV–, while IL‐4, −6 and −13 did not show any changes. Correlation analysis showed dependency of accelerated autoimmunity and β cell destruction on increased IFN‐γ, IL‐12 and IL‐17 versus decreased IL‐4, −6 and −13. In conclusion, IFN‐γ, IL‐12 and IL‐17 played an essential role in exacerbating EV+‐T1D, while C3d, sC5b −9, IL‐10 and −20 displayed distinct patterns.
A Double-Blind, Randomized, Prospective Evaluation of the Efficacy and Safety of Risperidone Versus Haloperidol in the Treatment of Schizoaffective Disorder

The relative efficacy and safety of risperidone versus haloperidol in the treatment of schizoaffective disorder was studied. Sixty-two patients (29 depressed type; 33 bipolar type) entered a three-site, randomized, double-blind, 6-week trial of risperidone (up to 10 mg/day) or haloperidol (up to 20 mg/day). Trained raters assessed baseline, weekly, and end-of-study levels of psychopathology with the Positive and Negative Syndrome Scale (PANSS), the 24-item Hamilton Rating Scale for Depression (HAM-D-24) and the Clinician-Administered Rating Scale for Mania (CARS-M). The authors were unable to statistically distinguish between risperidone and haloperidol in the amelioration of psychotic and manic symptoms. In addition, there was no difference in worsening of mania between the two agents in either subgroup (i.e., depressed or bipolar subgroups). For the total PANSS, risperidone produced a mean decrease of 16 points from baseline compared with a 14-point decrease with haloperidol. For the total CARS-M scale, risperidone and haloperidol produced mean change scores of 5 and 8 points, respectively, and for the CARS-M Mania subscale, 3 and 7 points, respectively. Additionally, risperidone produced a mean decrease of 13 points from the baseline 24-item HAM-D, compared with an 8-point decrease with haloperidol. In those patients who had more severe depressive symptoms (i.e., HAM-D baseline score >20), risperidone produced at least a 50% mean improvement in 12 (75%) of 16 patients in comparison to 8 (38%) of 21 patients receiving haloperidol. Haloperidol produced significantly more extrapyramidal side effects and resulted in more dropouts caused by any side effect. There was no difference between risperidone and haloperidol in reducing both psychotic and manic symptoms in this group of patients with schizoaffective disorder. Risperidone did not demonstrate a propensity to precipitate mania and was better tolerated than haloperidol. In those subjects with higher baseline HAM-D scores (i.e., >20), risperidone produced a greater improvement in depressive symptoms than haloperidol.
Dissolution rate enhancement, in vitro evaluation and investigation of drug release kinetics of chloramphenicol and sulphamethoxazole solid dispersions

Formulation of solid dispersions is one of the effective methods to increase the rate of solubilization and dissolution of poorly soluble drugs. Solid dispersions of chloramphenicol (CP) and sulphamethoxazole (SX) as model drugs were prepared by melt fusion method using polyethylene glycol 8000 (PEG 8000) as an inert carrier. The dissolution rate of CP and SX were rapid from solid dispersions with low drug and high polymer content. Characterization was performed using fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). FTIR analysis for the solid dispersions of CP and SX showed that there was no interaction between PEG 8000 and the drugs. Hyper-DSC studies revealed that CP and SX were converted into an amorphous form when formulated as solid dispersion in PEG 8000. Mathematical analysis of the release kinetics demonstrated that drug release from the various formulations followed different mechanisms. Permeability studies demonstrated that both CP and SX when formulated as solid dispersions showed enhanced permeability across Caco-2 cells and CP can be classified as well-absorbed compound when formulated as solid dispersions.
Vascular Complications of Pancreas Transplantation

Objective: The purpose of our study was to focus on the early diagnosis and treatment of vascular complications after simultaneous pancreas-kidney (SPK) transplantation. Description of the technique for salvage of the graft after venous thrombosis (VT) is also provided. Methods: From July 1994 to December 2002, 14 patients of 206 SPK transplant recipients had partial VT. Partial splenic VT (PSVT) was documented in 10 patients (4.8%), two had complete thrombosis of the splenic vein, one partial superior mesenteric thrombosis, and one developed partial thrombosis of the splenic and superior mesenteric vein. Four patients developed complete VT of the pancreas allograft and one superior mesenteric artery thrombosis. Our experience with four arteriovenous fistulae is also reported. The immunosuppression included tacrolimus, steroids, and monoclonal antibody to the IL-2 receptor. Thymoglobulin was introduced in June 2000 in our protocol combined with rapamycin or mycophenolate mofetil. These cases were identified following the intravenous (iv) use of tacrolimus with or without anti-IL-2R therapy. One case of complete VT is also reported one month following transplantation in a recipient with high rapamycin levels. Diagnosis was established during routine color Doppler ultrasonography. Results: Partial VT was effectively treated with anticoagulation. Complete VT required surgical thrombectomy. In our series, the pancreas was salvaged successfully in all patients with the technique described here. Conclusion: Early diagnosis of vascular complications after pancreas transplantation is of paramount importance for the appropriate treatment with organ salvage. Based on our experience, we suggest that VT can be effectively treated with anticoagulation. Aspirin is sufficient for PSVT.
Bandwidth enhancement and size reduction of microstrip slot antennas

Reduced size microstrip monopole slot antennas with different slot shapes-straight, L and inverted T, and placed on a small ground plane, are investigated. The ground plane size is 50 mm/spl times/80 mm, which is about the size of a typical PC Wireless card. Detailed simulation and experimental investigations are conducted to understand their behavior and optimize for broadband operation. It is shown that, the variation in the slot shape, from straight to L and T shapes, helps in generating additional resonances, which when coupled to the original resonances of the slot, further increases impedance bandwidths. The bent shapes of the L and T slots reduce their height and provide more space on the ground plane for electronics. A mirror image dual L-slot antenna, placed at two adjacent corners of the ground plane, is also investigated and optimized for the polarization diversity. They provide an impedance bandwidth of 87%, with near orthogonal radiation characteristics. The measured impedance bandwidths (S/sub 11/=-10 dB) of up to 60%, 84%, and 80% are achieved for these straight, L and inverted T slots respectively, by suitably selecting their design parameters. The simulation results are in good agreement with the experimental data considering several practical issues.
Osteochondral Transplantation of the Talus

Background: Osteochondral lesions of the ankle are a common injury after ankle sprains, especially in young and active patients. The Osteochondral Autograft Transfer System (OATS) is the only 1-step surgical technique designed to replace the entire osteochondral unit. Purpose: This study was conducted to evaluate the long-term clinical and radiographic outcomes of the OATS procedure for the talus and compare the results of patients who have had prior surgical interventions with patients for whom OATS represents the primary surgical treatment. Study Design: Case series; Level of evidence, 4. Methods: The authors retrospectively analyzed 26 talus OATS procedures (25 patients) with an average follow-up of 84 months (range, 53-124 months); 9 patients had OATS as a second surgical intervention. The patients completed the American Orthopaedic Foot & Ankle Society (AOFAS) and Tegner scores plus the visual analog scale (VAS) preoperatively and at follow-up. Magnetic resonance imaging examinations were conducted on a 1.5-T whole-body magnet that assessed transplant congruency, adjacent surface of the talus, the corresponding distal tibia, and joint effusion. Results: The authors found significant increases for the AOFAS score (50 to 78 points, P < .01) and the Tegner score (3.1 to 3.7, P < .05) and a significant decrease for the VAS (7.8 to 1.5, P < .01) from preoperative to postoperative. Patients with normal integration or minor incongruity of the transplant on magnetic resonance imaging (81%) had significantly better AOFAS scores (P = .03). Other magnetic resonance imaging criteria did not predict clinical results. Patients for whom OATS represented a second procedure had significantly worse clinical AOFAS and Tegner scores plus a higher VAS. Conclusion: Long-term clinical and magnetic resonance imaging results after osteochondral transplantation are good and patients significantly benefit from this surgery. Magnetic resonance imaging should not be a routine control but appears to be indicated when clinical symptoms persist after osteochondral transplantation.
Risk Factors for Lower Extremity Arterial Disease in Non‐insulin‐dependent Diabetic Persons

The relationship of lower extremity arterial disease to the different risk factors for atherosclerosis in non‐insulin‐dependent (Type 2) diabetes mellitus is a matter of continuing investigation. The present study was conducted on a random sample of 193 non‐insulin‐dependent diabetic patients in order to compare the frequency and severity of some known risk factors for atherosclerosis among such persons with and without indications of lower extremity arterial disease. Conventional risk factors for atherosclerosis (smoking, existence of hypertension, total plasma cholesterol, HDL‐cholesterol, and triglycerides) were assessed. In addition body mass index, waist‐to‐hip ratio, body fat mass, and albumin excretion were determined. Criteria for the presence of lower extremity arterial disease were an ankle brachial pressure index < 0.89 and/or the existence of intermittent claudication. Age, length of diabetes, and waist‐to‐hip ratio appeared to be factors significantly related to lower extremity arterial disease in most cases. Blood lipids, body mass index, HbA1 (except in males), smoking, and type of antidiabetic treatment were not significantly related to disease. The multivariate analysis confirmed the significant contribution of the duration of diabetes (p = 0.002), and waist‐to‐hip ratio (p = 0.024) and further showed a significant relation with triglycerides (p = 0.020). Thus, lower extremity arterial disease in non‐insulin‐dependent diabetes mellitus is significantly related to a long duration of diabetes and to central body fat distribution (but not to body mass index), as well as to triglyceride levels.
Cutting Edge: The Orphan Chemokine Receptor G Protein-Coupled Receptor-2 (GPR-2, CCR10) Binds the Skin-Associated Chemokine CCL27 (CTACK/ALP/ILC)1

We recently reported the identification of a chemokine (CTACK), which has been renamed CCL27 according to a new systematic chemokine nomenclature. We report that CCL27 binds the previously orphan chemokine receptor GPR-2, as detected by calcium flux and chemotactic responses of GPR-2 transfectants. We renamed this receptor CCR10. Because of the skin-associated expression pattern of CCL27, we focused on the expression of CCL27 and CCR10 in normal skin compared with inflammatory and autoimmune skin diseases. CCL27 is constitutively produced by keratinocytes but can also be induced upon stimulation with TNF-α and IL-1β. CCR10 is not expressed by keratinocytes and is instead expressed by melanocytes, dermal fibroblasts, and dermal microvascular endothelial cells. CCR10 was also detected in T cells as well as in skin-derived Langerhans cells. Taken together, these observations suggest a role for this novel ligand/receptor pair in both skin homeostasis as well as a potential role in inflammatory responses.
The Japanese Study Group of Insulin Therapy for Childhood and Adolescent Diabetes (JSGIT): initial aims and impact of the family history of type 1 diabetes mellitus in Japanese children

Abstract: The Japanese Study Group of Insulin Therapy for Childhood and Adolescent Diabetes (JSGIT) was established in July 1994 with the chief aim to improve the quality of therapy for type 1 diabetes in children, an entity far less common in Japan than in Europe. We proposed four initial research topics: (i) to determine the current status of medical care and glycemic control in Japanese children with type 1 diabetes mellitus; (ii) to standardize the measurement of hemoglobin A1c; (iii) to establish a registry of a large cohort of patients in order to enable prospective studies to improve the quality of therapy for children with type 1 diabetes in Japan; and (iv) to enable participants of the JSGIT to hold a workshop twice annually.
Timing of Cholecystectomy after Percutaneous Cholecystostomy for Acute Cholecystitis.

BACKGROUND/AIMS Laparoscopic cholecystectomy is the standard treatment for acute cholecystitis. Percutaneous cholecystostomy is an alternative treatment to resolve acute inflammation in patients with severe comorbidities. The purpose of this study is to determine the optimal timing of laparoscopic cholecystectomy after percutaneous cholecystostomy for the patients with acute cholecystitis. METHODS This retrospective study was conducted in patients who underwent cholecystectomy after percutaneous cholecystostomy from January 2010 through November 2014. Seventy-four patients were included in this study. The patients were divided into two groups by the operation timing. Group I patients underwent cholecystectomy within 10 days after percutaneous cholecystostomy (n=30) and group II patients underwent cholecystectomy at more than 10 days after percutaneous cholecystostomy (n=44). RESULTS There was no significant difference between groups in conversion rate to open surgery, operation time, perioperative complications rate, and days of hospital stay after operation. However, complications related to cholecystostomy such as catheter dislodgement occurred significantly more often in group II than group I (group I:group II=0%:18.2%; p=0.013). CONCLUSIONS Timing of laparoscopic cholecystectomy after percutaneous cholecystostomy did not influence postoperative outcomes. However, late surgery caused more complications related to cholecystostomy than early surgery. Therefore, early laparoscopic cholecystectomy should be considered over late surgery after percutaneous cholecystostomy insertion.
Caloric restriction augments brain glutamic acid decarboxylase‐65 and ‐67 expression

The ketogenic diet is a very low‐carbohydrate, high‐fat diet used to treat refractory epilepsy. We hypothesized that this diet may act by increasing expression of glutamic acid decarboxylase (GAD), the rate‐limiting enzyme in γ‐aminobutyric acid (GABA) synthesis. Thus, we evaluated brain GAD levels in a well‐established, seizure‐suppressing, rodent model of the ketogenic diet. Because the diet is most effective when administered with a modest (∼10%) calorie restriction, we studied three groups of animals: rats fed ad libitum standard rat chow (Ad lib‐Std); calorie‐restricted standard chow (CR‐Std); and an isocaloric, calorie‐restricted ketogenic diet (CR‐Ket). We found that GAD67 mRNA was significantly increased in the inferior and superior colliculi and cerebellar cortex in both CR diet groups compared with control (e.g., by 45% in the superior colliculus and by 71% in the cerebellar cortex; P < .001). GAD65 mRNA was selectively increased in the superior colliculus and temporal cortex in both CR‐Std and CR‐Ket diet groups compared with ad lib controls. The only apparent CR‐Ket‐specific effect was a 30% increase in GAD67 mRNA in the striatum (P = .03). Enhanced GAD immunoreactivity was detected in parallel with the mRNA changes. These data clearly show that calorie restriction increases brain GAD65 and ‐67 expression in several brain regions, independent of ketogenic effects. These observations may explain why caloric restriction improves the efficacy of the ketogenic diet in treating epilepsy and suggest that diet modification might be useful in treatment of a number of brain disorders characterized by impaired GAD or GABA activity. © 2004 Wiley‐Liss, Inc.
The prognosis of encephaloceles.

HE term "encephalocele" generally denotes a cephalic hernia through a congenital defect in the skull (cranium bifidum). The protrusions contain meninges and cerebrospinal fluid (cranial meningocele) and may also contain some portion of the brain (meningoencephalocele or encephalomeningocele). They may be partially or completely epithelialized. The great majority of encephaloceles are located in the occipital area. Anterior encephaloceles are uncommon and have been classified into sincipital varieties which visibly involve the nasofrontal region or the extremely rare basal ones which are hidden in the nasopharynx or orbit? The incidence of this malformation has been estimated at one in every 3000 to 10,000 live births. 11,~2 The clinical manifestations and surgical management of encephaloceles have been described in reports dealing for the most part with the larger related problems of spina bifida and myelomeningocele. ~,7,1~ There are no comprehensive surveys on the morbidity and the quality of survival in individuals born with different types of encephaloceles. I~rber, 11 however, has recently reviewed the prognosis of occipital encephaloceles in a series of infants. There is no comparison of the long-term outlook with this condition before and after ventriculoatrial shunt operations were widely adopted for controlling the hydrocephalus associated with many encephaloceles. This report analyzes the morbidity of encephaloceles and the results of treatment over a 20-year span through 1967 at the Indiana University Medical Center. The study interval includes the decade immediately before and that just after the first ventriculoatrial shunting operations were done at this in
