Patients with fibromyalgia (FM) show widespread pain associated with other symptoms such as cognitive problems, depression, and anxiety among others associated with alterations in the central nervous system. The hippocampal subfields had differences in function, histology, and connectivity with other brain regions, and are altered in different diseases. This study evaluates the volumetric differences between patients with FM compared with a healthy control group. A total of 49 women with, and 43 healthy women completed this study. T1-weighted MRI was used to assess brain volume, and FreeSurfer software was used to segment the hippocampal subfields. Women with FM had a significant reduction in most of the hippocampal subfields. The regression equation models were obtained to predict the volume of specific subfields of the right and left hippocampus. These findings provide that women with FM have lower hippocampal subfields volumes compared with healthy women. Besides, regression models show that different covariates, such as age, cognitive impairment, or depression, are related to specific subfields.

Tributyltin (TBT) compounds have been used as anti-fouling agents and the central nervous system is one of its target organs. TBT-induced modulations of neurotransmitters in the brains of adult mice have been reported. However, little is known about the developmental neurotoxicity of TBT. In this study, we evaluated the effects of TBT on neurotransmitters and their metabolites in discrete brain regions of female ICR mice and their offspring. Pregnant ICR mice were exposed to TBT chloride at concentrations of 0, 15 or 50 ppm in water or 125 ppm in food. Male offspring were sacrificed at one, two and three weeks after birth. The concentrations of norepinephrine, dopamine (DA), dihydoxyphenylacetic acid, homovanillic acid (HVA), serotonin (5-HT), and 5-hydroxyindoleacetic acid (5-HIAA) were determined in different brain regions by HPLC. All offspring from the 125 ppm group died immediately after birth. A significant decrease in the body weight of the TBT-treated F1 groups compared to the control group was observed in the first week. Significant increases compared to the controls were observed for the DA concentration in the striatum of the 50 ppm F1 group, and for the HVA concentration in the cerebrum and the 5-HT concentration in the medulla oblongata of the 15 and 50 ppm F1 groups in the third week. At three weeks of age, the neurotransmitters and their metabolites may be useful indexes for developmental neurotoxicity. For the dams, a significant decrease in the 5-HT concentration was observed in the cerebellum, medulla, midbrain and striatum of the 125 ppm group compared to the control group. A significant decrease in the 5-HIAA concentration was also observed in the cerebellum, midbrain and striatum of the dams in the 125 ppm group compared to the control. TBT may induce a decrease in the synthesis of 5-HT in the dams. The discrepancy between dams and offspring may be due to several factors such as age, dose, route, sex and pregnancy.

SummaryObjective: The aim of the study was to investigate the use of somatic cell count (SCC) and aerobic bacterial counts as possible tools to choose animals for selective dry cow treatment (DCT) on cow level. Blanket antibiotic DCT is an approved and common method in Germany aimed at increasing the cure rate of existing intramammary infections (IMI) at the time of drying off and decreasing the risk of new infections during the dry period. However, not all animals benefit equally from an antibiotic DCT. Moreover, dairies, consumers and politicians demand a reduction in the use of antibiotics in farm animals. Several criteria for identifying animals which would benefit from antibiotic DCT have been described in the literature. Material and methods: Animals chosen for this investigation were divided into three study groups: Aerobic Count Petrifilm® group A (153 cows), SCC group S (160 cows) and control group C (169 cows). All quarters were treated with an internal teat sealant (ITS) no matter which group the cows belonged to. Results: Group C, in which all cows received an antibiotic DCT, achieved the best results referred to udder health, particularly regarding bacteriological dry period cure. However, the results of the two study groups A and S, in which the animals were dried off selectively, were only marginally worse. A significant difference regarding bacterial dry period cure was revealed between group S and group C (p = 0.039), whereas no significant difference concerning new IMI risk could be detected between the three study groups. Compared to a blanket antibiotic DCT of all cows in the corresponding study group, a reduction of the usage of antibiotics of 23.5 % (A) and 55 % (S) was noticed, respectively. Furthermore, it could be shown that the lactation number as well as the microorganisms present at the time of drying off influence udder health. Conclusion: Selective DCT is an alternative method to the widespread blanket antibiotic DCT. However, it has to be mentioned that selective DCT involves the described marginal decline in udder health and the additional amount of time, which might arise from the procedure of choosing the right animals and performing the applied rapid test methods.

Neuromyelitis optica (NMO) is an inflammatory, demyelinating disease of the central nervous system characterized by the association of a serious myelitis and unilateral or bilateral optic neuritis. The present study aimed to analyze the immunological parameters of NMO patients with diagnosis established based on Wingerchuck et al. (1999) criteria. Production of IgG and IgA antibodies to antigens of MBP, PLP 95-116, MOG 92-106, and the cytokines interleukin-4 (IL-4) and interferon-γ (INF-γ) were assessed by Elisa assay. The cohort was formed by 28 NMO patients and a matched healthy control group. NMO patients had significant high levels of IgG to MOG (p<0.0001), PLP (p=0.0002) and MBP (p<0.0001), and solely IgA to MBP (p<0.0001). INF-γ (p=0.61) levels were similar to healthy controls. Increased production of IL-4 (p=0.0084) indicates an important role for this cytokine in the activation of Th2 regulatory cells and of the IgA producers B lymphocyte indicating activation of humoral immunity.

In this paper we want to demonstrate whether higher than normal levels of RDW, and lower than normal levels of MPV can be used as indicators of subclinical inflammation and tools for treatment decision in FMF or not. The participants in this study included 89 patients with FMF during attack-free periods and 30 healthy controls. The RDW and platelet counts were significantly higher, while the MPV was significantly lower in the patients with FMF group than healthy control group (P<0.001;P=0.005;P<0.001, resp.). In the attack-free FMF group, a negative correlation was found between the MPV and RDW values (P<0.001,r=-0.40). The positive correlation was found between the RDW and ESR (r=0.23,P=0.028). And the negative correlation was found between the MPV and CRP (r=-0.216,P=0.042). Consequently, our results suggest that low MPV and high RDW levels may provide additional information about subclinical inflammation in FMF patients. But other strong predisposing factors affecting subclinical inflammation in FMF should be considered. Further studies with large numbers of patients are needed. Treatment of FMF should include not only prevention of acute attacks but also decreasing of the subclinical inflammation.

A developmental neurotoxicity study was conducted to generate additional data on the potential functional and morphological hazard to the central nervous system caused by ammonium perchlorate in offspring from in utero and lactation exposure. Female Sprague-Dawley rats (23 to 25/group) were given continuous access to 0 (carrier), 0.1, 1.0, 3.0, and 10.0 mg/kg-day perchlorate in the drinking water beginning 2 weeks prior to mating and continuing through day 10 of lactation for the behavioral function assessment or given continuous access to 0 (carrier), 0.1, 1.0, 3.0, and 30.0 mg/kg-day beginning on gestation day 0 and continuing through day 10 of lactation for neurodevelopment assessments. Motor activity was conducted on postpartum days 14, 18, and 22 and juvenile brain weights, neurohistopathological examinations, and regional brain morphometry were conducted on postpartum days 10 and 22. This research revealed a sexually dimorphic response, with some brain regions being larger in perchlorate-treated male rats than in comparable controls. Even so, there was no evidence of any obvious exposure-related effects on male rat brain weights or neuropathology. The most consistent exposure-related effect in the male pups was on the thickness of the corpus callosum, with both the right- and left-sided measures of the thickness of this white matter tract being significantly greater for the male pups in the 0.1 and 1.0 mg/kg-day exposure groups. The behavioral testing suggests prenatal exposure to ammonium perchlorate does not affect the development of gross motor movements in the pups.

Addiction is the most critical form of Addiction. It is a chronic disease with a potential for fatality if not treated. In this work, 180 samples of male individuals were collected in this study. They classified into three groups, groups:  G1 who were healthy control; G2 who was addicted to methamphetamine (meth); G3 who was addicted to tramadol (Tra). Each group consists of 60 heavy smokers Iraqi male individuals in the age range of 18-43 years. The results showed a highly significant increase (p<0.0001) in the level of Glucose of the two addicted groups in comparison with the healthy group. A highly significant decrease (p<0.0001) could be seen in the level of Zn of the two addicted groups G2, G3 compared to the control group, while the level of Cu of the two addicted groups were highly significant increased (p<0.0001). Also, the results showed a highly significant difference (p<0.0001) in BMI for the studied groups, G2, G3 in comparison with the control group. All addictive individuals under this study were at normal weight depending on their BMI.

The efficacy of pulmonary vein antral isolation for patients with prolonged sinus pauses (PSP) on termination of atrial fibrillation has been reported. We studied the right atrial (RA) electrophysiologic and electroanatomic characteristics in such patients. Forty patients underwent electroanatomic mapping of the RA: 13 had PSP (group A), 13 had no PSP (group B), and 14 had paroxysmal supraventricular tachycardia (control group C). Group A had longer P-wave durations in lead II than did groups B and C (115.5 ± 15.4 vs 99.5 ± 10.9 vs 96.5 ± 10.4 ms; P=0.001), and RA activation times (106.8 ± 13.8 vs 99 ± 8.7 vs 94.5 ± 9.1 s; P=0.02). Group A's PP intervals were longer during adenosine triphosphate testing before ablation (4.6 ± 2.3 vs 1.7 ± 0.6 vs 1.5 ± 1 s; P &lt;0.001) and after ablation (4.7 ± 2.5 vs 2.2 ± 1.4 vs 1.6 ± 0.8 s; P &lt;0.001), and group A had more complex electrograms (11.4% ± 5.4% vs 9.3% ± 1.6% vs 5.8% ± 1.6%; P &lt;0.001). Compared with group C, group A had significantly longer corrected sinus node recovery times at a 400-ms pacing cycle length after ablation, larger RA volumes (100.1 ± 23.1 vs 83 ± 22.1 mL; P=0.04), and lower conduction velocities in the high posterior (0.87 ± 0.13 vs 1.02 ± 0.21 mm/ms; P=0.02) and high lateral RA (0.89 ± 0.2 vs 1.1 ± 0.35 mm/ms; P=0.04). We found that patients with PSP upon termination of atrial fibrillation have RA electrophysiologic and electroanatomic abnormalities that warrant post-ablation monitoring.

Abstract Study Objectives Subjective reports of sleep impairments are common in individuals with posttraumatic stress disorder (PTSD), but objective assessments of sleep have yielded mixed results. Methods We investigated sleep via actigraphy and e-diary on 6 consecutive nights in a group of 117 women with PTSD after childhood abuse (CA; PTSD group), a group of 31 mentally healthy women with a history of CA (healthy trauma controls, HTC group) and a group of 36 non-traumatized mentally healthy women (healthy controls, HC group). Results The PTSD group reported lower sleep quality, more nights with nightmares, and shorter sleep duration than both HTC and HC. Actigraphic measures showed more and longer sleep interruptions in the PTSD group compared to HTC and HC, but no difference in sleep duration. While the PTSD group underestimated their sleep duration, both HTC and HC overestimated their sleep duration. HTC did not differ from HC regarding sleep impairments. Conclusions Sleep in women with PTSD after CA seems to be more fragmented but not shorter compared to sleep patterns of mentally healthy control subjects. The results suggest a stronger effect of PTSD psychopathology on sleep compared to the effect of trauma per se.

Abstract Background Limited survival area is an intractable problem in the clinical practice of prefabricated flaps. This study compared four strategies to find an effective method and to understand the potential mechanisms for supercharging. Methods A prefabricated abdominal flap rodent model was prepared. Rats were randomly divided into five groups (n = 6/group). (A) Control group: prefabricated right side femoral vessels. Based on group A, various prefabricated vessels were added; (B) proximal venous supercharging group: right side superficial inferior epigastric vein (SIEV); (C) proximal arterial supercharging group: right side superficial inferior epigastric artery (SIEA); (D) distal venous supercharging group: left side SIEV; and (E) distal arterial supercharging group: left side SIEA. Macroscopic analysis, near-infrared fluorescence imaging, and microscopy were used to analyze the survival area, fluorescence area, and capillary density. Results No significant differences in survival areas were found among supercharging groups (B–E), which were larger than in the control group. Near-infrared fluorescence imaging showed the areas of control and venous supercharging groups (A, B, and D) were smaller than in arterial groups (C and E). Capillary density areas in the right part of the flap in proximal supercharging groups (B and C) and left part of the flap in distal supercharging groups (D and E) were all greater than group A, with no significant differences among the other groups. Conclusion Enhanced neovascularization is a useful supercharging strategy. Both arterial and venous vessel supercharging improved the survival area of prefabricated flaps.

Capsular contracture is the most common complication after insertion of silicone implants during breast implant surgery. The discovery that myofibroblasts play an important role in the formation of hypertrophic scars led to the development of pharmacological drugs such as zafirlukast, which prevents capsular contracture by resisting the above mechanism. As a result, the author sought to investigate the effect of the anti-leukotriene montelukast on capsular contracture. Ten white female New Zealand rabbits, each weighing approximately 3 kg, were used as subjects. Through bilateral incision of the midback area, the prostheses were inserted on the subpanniculus carnosus plane. Once the silicone prostheses had been inserted, the right implant was injected with 10 mL of montelukast (10 µg/mL), and the left implant was injected with 10 mL of normal saline. Eight weeks after the procedure, the capsular pressure was measured via tonometry using a circular glass piece weighing 42.7 g. The tissue samples were then extracted, and their thicknesses were measured using hematoxylin-eosin stain and Masson trichrome stain. The average pressure was 4.23±0.99 mmHg in the control group and 3.71±0.51 mmHg in the experimental group, a statistically significant difference (p = 0.02). The average capsular thickness was 947.938±300 µm in the control group and 709.672±274 µm in the experimental group, a statistically significant difference (p = 0.028). The author confirmed that montelukast injections during silicone prosthesis insertion decreased the formation of capsular contracture.
