Clinical features for 89 deaths of hand, foot and mouth disease in Guangxi, China, 2014

ObjectivesThe aim of this study is to summarize the risk factors of severe Hand, foot and mouth disease (HFMD) and explore the clinical characteristics of pulmonary edema (PE) and non-PE in the deceased patients with HFMD. MethodsWe identified 89 HFMD deaths which were separated into the PE group or non-PE group. Next, patients were divided based on their initial admission to hospitals as stage 1, 2, 3, or 4; at this point, their clinical manifestations were compared. ResultsThere were 87 cases in the PE group, and 2 cases in the non-PE group. In the PE group, the difference in median time for patients at different stages from onset to symptoms, showed no significant difference (p>0.05). The etiology was detected as a positive rate for enterovirus 71 (EV71) of 89.19%, which showed a more severe course than other etiologies. The white blood cell (WBC) counts, lymphocyte (LYM) counts and creatine kinase MB (CK-MB) counts of patients admitted in different stages increased significantly with severity (p<0.05). ConclusionsThere may be two clinical subtypes, mostly PE and rarely non-PE, in the deceased patients with HMFD. EV71 and risk factors such as an increased WBC count are associated with a severe course of HMFD.

Hand eczema as a risk factor for food allergy among occupational kitchen workers

BackgroundAn increasing number of studies in children is highlighting the importance of transdermal routes of exposure to food allergens through damaged skin in the pathogenesis of food allergies. However, data on this in adults are limited. A few case-series studies has documented development of food allergy among kitchen workers with hand eczema after direct contact exposure to foods. MethodsTo explore the significance of hand eczema as a risk factor for food allergies in adults at the epidemiological level, we performed a cross-sectional web-based questionnaire survey on kitchen workers whose exposures were classed as occupational (cooks and food handlers, n = 1592) or non-occupational (housewives, n = 1915). Logistic regression was used to explore the association between the presence/severity of hand eczema and the risk of food allergy after adjustment for potential confounders. ResultsCurrent hand eczema and current diagnosed food allergy were more common among occupational kitchen workers (OKW) than among non-occupational kitchen workers (NOKW) (32.3%-vs-29.9% and 9.9%-vs-3.8%, respectively). Current hand eczema was significantly associated with increased risk of current diagnosed food allergy in OKW (adjusted odds ratio 2.4, 95% CI 1.6–3.7). Those with more severe hand eczema were more likely to suffer from allergic symptoms for foods, and diagnosed food allergy. ConclusionsThis study illustrates a significant public health problem in the adult population, documenting a major impact of hand eczema on the ongoing adult food allergy epidemic.

Formulation and In Vitro Release Kinetics of Mucoadhesive Blend Gels Containing Matrine for Buccal Administration.

Enterovirus 71 (EV71) is a pathogenic factor of severe hand, foot, and mouth disease (HFMD). No vaccine or specific treatment is currently available for EV71 infection. Hence, we developed a buccal mucoadhesive gel containing matrine to protect against HFMD. Mucoadhesive gels were prepared by Carbopol 974P and were combined with Carbopol 971P, sodium carboxymethyl cellulose (CMC-Na), or hydroxypropylmethy cellulose (HPMC K100M). The formulations were characterized in terms of tensile testing and continuous flow techniques for mucoadhesion. The rheological studies and in vitro drug release characteristics were also investigated. The results showed that combinations of two polymers significantly improved mucoadhesion, especially Carbopol 974P blended with HPMC. Carbopol 974P to HPMC blend ratios of 1:1 and 2:1 induced better mucoadhesion in the tensile test and continuous flow method, respectively. The most sustained release was obtained at a Carbopol 974P to HPMC ratio of 2.5:1. A predominantly non-Fickian diffusion release mechanism was obtained. The gel containing 2.5% Carbopol 974P combined with 1% HPMC showed good mucoadhesion properties and sustained drug release.

Botulinum Toxin in Parkinson Disease Tremor: A Randomized, Double-Blind, Placebo-Controlled Study With a Customized Injection Approach

BackgroundIn essential tremor and Parkinson disease (PD) tremor, administration of onabotulinumtoxinA via a fixed injection approach improves the tremor, but many patients (30%-70%) develop moderate to severe hand weakness, limiting the use of onabotulinumtoxinA in clinical practice. ObjectiveTo evaluate the safety and efficacy of incobotulinumtoxinA (IncoA) injection for the treatment of tremor in PD. Patients and MethodsIn this double-blind, placebo-controlled, crossover trial, 30 patients each received 7 to 12 (mean, 9) IncoA injections into hand and forearm muscles using a customized approach. The study was performed from June 1, 2012, through June 30, 2015, and participants were followed for 24 weeks. Treatment efficacy was evaluated by the tremor subsets of the Unified Parkinson's Disease Rating Scale and the Patient Global Impression of Change 4 and 8 weeks after each of the 2 sets of treatments. Hand strength was assessed using an ergometer. ResultsThere was a statistically significant improvement in clinical rating scores of rest tremor and tremor severity 4 and 8 weeks after the IncoA injection and of action/postural tremor at 8 weeks. There was a significant improvement in patient perception of improvement at 4 and 8 weeks in the IncoA group. There was no statistically significant difference in grip strength at 4 weeks between the 2 groups. ConclusionInjection of IncoA via a customized approach improved PD tremor on a clinical scale and patient perception, with a low occurrence of significant hand weakness.

Complete Genome Sequences of Four Coxsackievirus A16 Strains Isolated from Four Children with Severe Hand, Foot, and Mouth Disease.

ABSTRACTHere, we report the complete genome sequences of four coxsackievirus A16 strains isolated from four children with severe hand, foot, and mouth disease. Three of them were assigned to subgenotype B1b based on phylogenetic analysis of the VP1 gene, and the other one belonged to subgenotype B1a.

Validation of the efficiency of a robotic rehabilitation training system for recovery of severe plegie hand motor function after a stroke.

We have developed a rehabilitation training system called the Useful and Ultimate Rehabilitation System PARKO (UR System PARKO) to promote the recovery of motor function of the severe chronic plegic hand of stroke patients. This system was equipped with two functions to realize two conditions: (1) fixing of all fingers to a hyperextended position and (2) extending the elbow joint while applying resistance load to the fingertips. A clinical test was conducted with two patients to determine the therapeutic effect of the UR System PARKO for severe plegic hand. In both patients, the active ranges of motion of finger extension improved after training with the UR System PARKO. Moreover, the Modified Ashworth scale scores of finger extension increased. Thus, training reduced the spastic paralysis. These results suggest the effectiveness of training with the UR System PARKO for recovery of motor function as reflected in the finger extension of the severe plegic hand.

DIFFERENCES BETWEEN MULTI-INFARCT DEMENTIA AND SMALL-VESSEL DISEASE DEMENTIA IN ATTENTION AND WORKING MEMORY DEFICITS

Attention and working memory deficit are significantly impaired in patients with small vessel disease dementia, but little is known about diferences in these cognitive domains between subtypes of vascular dementia. 60 patients were studied, 28 were randomised as multi infarct dementia (MID) and 32 in small vessel disease dementia (SVD), according to NINDS- AIREN (National Institute of Neurological Disorders and Stroke and Association Internationale pour la Recherché et l'Enseignement en Neurosciences) neuroradiological criteria. Patients with MMSE (Mini Mental State Examination) score 15–25 were included. Groups have been matched by sex, age and education. Patients with severe aphasia, depression, and hand weakness were excluded. Trail Making Test (TMT) A and B form was used to evaluate: processsing information speed, visuo- conceptual functions, visuo-motor tracking and attention. WMS- R(Wechsler Memory Scale – Revised) visual span subtest and digit-symbol coding subtest on the Wechsler Test of Intelligence was used to measure visual abilities and digit span for verbal capacities of attention and working memory. Processing information speed was significantly slower, and conceptual skills were more impaired in MID than in SVD group (p = 0,012), with coefficient of discrimination between reaction time 0,068 for TMTA and 0,022 for TMT B. There were no differences between groups in verbal and visual span WMS-R scores forward, but either verbal or visual backward scores and Digit Symbol Test score were significantly lower in MID (p=0,002). Coefficient of discrimination for verbal span backward was 0.122, for visual span backward was 0.109, for verbal span forward was 0,066 and for visual span forward was 0,064. The most predicatable scores were proposed for each group of vascular dementia patients (MID ˂2, SVD 3 and ˃3 for verbal span backward; MID ˂2, SVD 4 and ˃4 for visual span forward, MID ˂ 4, SVD 6 and ˃6 for visual span forward MID ˂3, SVD 4 and ˃4 for visual span forward; MID 0, SVD 1–6, and ˃6 for digit symbol coding). Attention and working memory deficit are more severe in MID than SVD.

Derivation and Validation of a Mortality Risk Score for Severe Hand, Foot and Mouth Disease in China

Outbreaks of hand, foot and mouth disease (HFMD) have increased recently, as has the case fatality rate in severe cases. No scoring system currently exists to predict mortality risk for severe HFMD in previous study. We retrospectively collected laboratory parameters for 546 patients with severe HFMD (a derivation and a validation cohort) at Hunan Children’s Hospitals between January 2012 and December 2014. We developed a mortality risk score comprising four laboratory parameters: blood glucose (GLU), white blood cells (WBC), lactate (LAC), and N-terminal-probrain natriuretic peptide (NT-proBNP). Using an “optimal” cutoff score of 4, the sensitivity, specificity, positive predictive value and negative predictive value was 88.00%, 96.14%, 62.86% and 99.08%, respectively, in the derivation cohort. Among severe HFMD patients with low- and high-risk scores in the validation cohort, case fatality rates were 1.49% and 74.07%, respectively. According to the “optimal” cut-off in the derivation cohort, the sensitivity, specificity, positive predictive value, and negative predictive value were 80.95%, 93.83%, 62.96% and 97.44%, respectively, in the derivation cohort. The mortality risk score demonstrated good discrimination (AUC > 0.9) and calibration (P > 0.05) in both cohorts. The mortality risk score, comprising WBC, GLU, LAC and NT-proBNP, has been demonstrated good discrimination and calibration in the both cohorts.

Clinical Evaluation of UR-System-PARKO for Recovery of Motor Function of Severe Plegic Hand after Stroke

The first author has developed TANABE therapy for severe hemiplegic stroke patients. In this paper we developed a training system (UR-System-PARKO) on the basis of TANABE therapy. The clinical test of the therapeutic effect of the UR-System-PARKO was performed in severe plegic hand. The results show the effectiveness of the training by the UR-System-PARKO for recovery of motor function for finger extension of the severe plegic hand.

Severe hand, foot and mouth disease associated with Coxsackievirus A10 infections in Xiamen, China in 2015

BackgroundCoxsackievirus A10 (CV-A10) is one of the etiological agents associated with hand, foot and mouth disease (HFMD) and usually causes mild cases. During 2009–2014, no severe cases caused by CV-A10 was reported in Xiamen, China, however, an increase in cases was seen in 2015. ObjectivesWe aimed to perform a retrospective molecular epidemiological analysis of HFMD associated with CV-A10 infections in Xiamen. Study designCV-A10 VP1 (n=41) capsid and full-length or near full-length genomes (n=14) were sequenced. Phylogenetic trees were constructed based on these sequences and other reference sequences and nucleotide and amino acid changes were characterized. ResultsFrom 2009–2014, no laboratory-confirmed CV-A10 infections associated with severe cases were identified, however, in 2015, 39% (7/18) of severe HFMD cases were CV-A10 infections. Sequence analysis of severe and non-severe CV-A10 HFMD cases determined that severe cases predominantly clustered with an emerging clade E lineage A strain which contained 4 nucleotide changes in 5′ UTR and 5 amino acid substitutions in structural and non-structural proteins. ConclusionsThe results indicate CV-A10 infection may be emerging as a new and major cause of severe HFMD and CV-A10 surveillance should be increased and considered in HFMD prevention and control strategies.

Clinical Significance and Prognostic Effect of Serum 25-hydroxyvitamin D Concentrations in Critical and Severe Hand, Foot and Mouth Disease

Objective: To examine the association of serum 25-hydroxyvitamin D [25(OH)D] concentrations with critical and severe hand, foot and mouth disease (HFMD) and assess the clinical significance and prognostic effect of 25(OH)D concentrations in children with HFMD. Methods: This is a prospective observational study. The 138 children with HFMD were divided into common (49 cases), severe (52 cases), and critical (37 cases) HFMD groups. Another 59 healthy children undergoing outpatient medical examinations during the same period were chosen as the control group. Serum 25(OH)D concentrations were measured in all the subjects, and each group was subdivided by serum 25(OH)D concentration into 25(OH)D normal (≥30 ng/mL); insufficiency (20–29.9 ng/mL), and deficiency (<20 ng/mL) groups. The pediatric critical illness score (PCIS) was recorded for the critical and severe HFMD group upon admission to the pediatric intensive care unit (PICU). Children with critical and severe HFMD were also monitored for blood lactate (LAC), serum calcium ions (Ca++), D-dimer (DD), lactate dehydrogenase (LDH), and creatine kinase-MB (CK-MB) levels; the incidences of brainstem encephalitis, neurogenic pulmonary edema, and circulatory failure; and the 14-day mortality rate. Results: Serum 25(OH)D concentrations were generally low in all groups. The critical HFMD group showed a significantly lower serum 25(OH)D mean concentration (20.0 ± 8.4 ng/mL) and a higher proportion of deficiency (18%) compared with the control group (28.1 ± 6.6 ng/mL, 8%), common (29.5 ± 8.1 ng/mL, 10%) and severe (31.9 ± 9.7 ng/mL, 8%) HFMD groups (p < 0.05). In the critical and severe HFMD groups, the 25(OH)D deficiency group had lower PCISs than the 25(OH)D normal and insufficiency groups (p < 0.05); and had higher values than the latter two groups for LAC, LDH, CK-MB and DD; and the incidences of brainstem encephalitis, neurogenic pulmonary edema, circulatory failure, and mortality (p < 0.05). The death group showed significantly lower serum 25(OH)D concentrations and PCISs than the survival group (p < 0.05) and had higher LAC, LDH, CK-MB and DD levels and higher incidences of brainstem encephalitis, neurogenic pulmonary edema, and circulatory failure (p < 0.05). Logistic regression analysis revealed that the serum 25(OH)D concentration was an independent factor that influenced mortality in children with critical and severe HFMD. Conclusions: In this study, we find the serum 25(OH)D concentrations are substantially reduced in children with critical and severe HFMD and are associated with the severity of HFMD. The serum 25(OH)D concentrations may have clinical value for determining the progression of critical HFMD and predicting the risk of death. Further evidence is needed before it can be stated that 25(OH)D concentrations have clinical value in HMFD diagnosis.

Neuro-Magnetic Resonance Imaging in Hand, Foot, and Mouth Disease: Finding in 412 Patients and Prognostic Features.

PurposeThe aims of this study were to describe the neuroimaging findings in hand, foot, and mouth disease and determine those who may provide prognosis.Material and MethodsMagnetic resonance imaging scans in 412 severe hand, foot, and mouth disease between 2009 and 2014 were retrospectively evaluated. The patients who had the neurological signs were followed for 6 months to 1 year. According to the good or poor prognosis, 2 groups were categorized. The incidence of lesions in different sites between the 2 groups was compared, and multivariate analysis was used to look for risk factors.ResultsThe major sites of involvement for all patients with percentages were the medulla oblongata (16.1%), spinal anterior nerve roots (12.4%), thoracic segments (11.1%), brain or spinal meninges (8.3%), and so on. There were 347 patients (84.2%) with good prognosis and 65 (15.8%) with poor prognosis in the follow-up. There was a significantly higher rate of lesions involving the cerebral white substance, thalamus, medulla oblongata, pons, midbrain, and spinal cord in the group with poor prognosis. Multivariate analysis showed 2 independent risk factors associated with poor prognosis: lesions located in the medulla oblongata (P < 0.015) and spinal cord (P < 0.001) on magnetic resonance imaging; the latter was the most significant prognostic factor (odds ratio, 29.11; P < 0.001).ConclusionsWe found that the distribution patterns for all patients mainly involved the medulla oblongata, spinal anterior nerve roots, thoracic segments, and brain or spinal meninges. Our findings suggested that patients with lesions located in the medulla oblongata and spinal cord may be closely monitored for early intervention and meticulous management. For children with the symptom of nervous system, they are strongly recommended for magnetic resonance examination.

Drainage à pression négative en préopératoire des traumatismes complexes ouverts de la main : à propos de 17 cas

BackgroundFew studies have been conducted to explore the use of the vacuum sealing drainage (VSD) technique in complex hand injuries. The aim of this study was to report outcomes in patients with complex hand injuries receiving VSD as a coadjuvant treatment prior to second-stage surgery. MethodsThis case series study retrospectively reviewed the patients who underwent VSD for treatment of hand injuries. Inclusion criteria for the study were: (1) traumatic soft tissue defects of the hand and wrist, accompanied by different degrees of injury and exposure of bone, tendon, or blood vessel; (2) the wound surface of hand and wrist was seriously contaminated and direct wound closure was not possible; and (3) the soft tissues of hand and wrist were seriously lacerated or avulsed, and showed necrosis or acute infection. After debridement, one-stage and/or two-stage repairs using healthy adjacent tissues were performed and the wound was covered by the VSD materials. The non-cytotoxic polyethylene alcohol hydration seaweed salt foam was applied during the VSD treatment for its good biocompatibility. The drainage tube was connected to the vacuum equipment and the negative pressures were set at –60kPa to –40kPa. The VSD device was left in place for 5 to 7 days before removal. Either free skin grafting or skin flap transplantation was used for wound closure and/or reconstructive surgery. The hand injury severity score was used to assess wound severity. The surgical results were scored using the total active motion classification. ResultsA total of 17 patients (13 and 4 patients had major and severe hand injuries), averaging 33.8years were included. During the study period, 6 patients with severe hand injuries were not treated with VSD for the following reasons: (1) hemodynamic instability (n=1); (2) impaired coagulation function (n=1); (3) uncontrollable hemorrhage on the wound surface (n=2); and (4) exposure of the main blood vessels after surgical repair (n=2). VSD treatment was performed for an average of 7.4days (range, 6–14days) and the duration of wound healing averaged 23days (range, 20–43days). Wound infection was not reported prior to second-stage surgery. Only one of 17 patients had superficial necrosis at the flap edge, for a success rate of 94%. Average follow-up was 8.7months (range, 4–13months). Twelve (71%) patients reported excellent or good, four (23%) reported fair, and one (6%) reported poor results. ConclusionThe VSD can effectively promote safe and rapid repair of local soft tissues with good prognosis.

Topography of essential tremor

IntroductionTopography of tremor manifestations is poorly investigated in essential tremor. The present study explores the prevalence and clinical correlates of head and/or voice tremor in essential tremor. MethodsOut of a prospectively designed registry of 972 patients, 884 patients with definite and probable essential tremor had complete information on tremor localization. Demographic and clinical characteristics were compared among four subgroups: group A (without head or voice tremor, n = 619), B (with head but without voice tremor, n = 155), C (with voice but without head tremor, n = 47), and D (with both head and voice tremor, n = 63). ResultsIn our patients, total prevalence of tremor was 24.7% for head, 12.4% for voice and 7.1% for the combination of head and voice. Logistic regression analyses showed that female gender is strongly associated with head tremor, which was confirmed by an additional meta-analysis. Severe hand tremor was the only factor associated with voice tremor. Both female gender and severe hand tremor increase the odds for having the combination of head and voice tremor. For males, hand tremor severity is significantly increased among those with head and voice tremor alone and in combination, but for females only for the combination. Patients with both head and voice tremor have more frequent involvement of legs and other localizations and are less responsive to β-blockers. ConclusionsFemale gender and severe hand tremor may increase the odds of head and/or voice tremor in essential tremor. The association of hand tremor severity with midline tremor is stronger for males than females.

Holmes' Tremor with Shoulder Pain Treated by Deep Brain Stimulation of Unilateral Ventral Intermediate Thalamic Nucleus and Globus Pallidus Internus.

A 21-year-old male was admitted with severe right arm and hand tremors after a thalamic hemorrhage caused by a traffic accident. He was also suffering from agonizing pain in his right shoulder that manifested after the tremor. Neurologic examination revealed a disabling, severe, and irregular kinetic and postural tremor in the right arm during target-directed movements. There was also an irregular ipsilateral rest tremor and dystonic movements in the distal part of the right arm. The amplitude was moderate at rest and extremely high during kinetic and intentional movements. The patient underwent left globus pallidum internus and ventral intermediate thalamic nucleus deep brain stimulation. The patient improved by more than 80% as rated by the Fahn-Tolosa-Marin Tremor Rating Scale and Visual Analog Scale six months after surgery.

Cell injury induced by 3D protein of different enterovirus 71 strains

Objective To compare the degree of cell injury induced by 3D protein (SDLY11 and SDLY107) of enterovirus 71 (EV71) strains. Methods EV71 strains SDLY11 and SDLY107 were respectively isolated from children with mild and severe hand foot mouth disease. The target genes 11-3D-Flag and 107-3D-Flag were amplified by reverse transcription-polymerase chain reation (RT-PCR) and inserted into the eukaryotic expression vector pcDNA3.1. The recombinant plasmids 11-3D-Flag-pcDNA3.1 and 107-3D-Flag-pcDNA3.1 were transformed into Escherichia. coli DH5α, respectively, and were identified by enzyme digestion and sequencing. The recombinant plasmids were transfected into rhabdomyosarcoma (RD) cells, respectively. Expression of 3D protein was detected by indirect immunofluorescence assay and western blot. Cell injury induced by 3D protein was detected with lactate dehydrogenase (LDH) test, cell proliferation was detected by 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenylthiazolium bromide (MTT) test, and cell apoptosis was detected with Annexin-V and PI. Multiple comparisons among groups were analyzed using LSD-t test if multiple sets of variables were consistent with homogeneity of variance. If not, Dunnett T3 test was used. Results The 1 400 bp fragments were amplified by reverse tramscription (RT)-polymerase chain reaction (PCR), and the recombinant plasmids were digested by enzyme and the 1 400 bp and 5 400 bp fragments were obtained and identified. Gene sequencing showed that the sequences were consistent with the target genes. The specific fluorescence was observed by indirect immunofluorescence assay, and the western blot showed that the molecular weight of the target protein was 55×103. The LDH test showed that the A490 of SDLY11 3D protein transfection group (0.790±0.048) was higher than that of SDLY107 3D protein transfection group (0.641±0.018). The difference was statistically significant (t=5.14, P<0.05). The cell membrane damage caused by SDLY11 3D protein was more severe than SDLY107 3D protein. The MTT test showed that the A570 of SDLY11 3D protein transfection group (1.028±0.020) was lower than that of SDLY107 3D protein transfection group (1.081±0.002), and the difference was statistically significant (t=3.31, P<0.05). The effect on cell proliferation activity of SDLY11 3D protein was greater than SDLY107 3D protein. The results of Annexin-V/PI showed that the percentage of apoptotic cells of SDLY11 3D protein transfection group and SDLY107 3D protein transfection group were (1.471±0.246)% and (1.465±0.237)%, respectively, and the difference was not statistically significant (t=0.04, P=0.973). Conclusions Compared with the SDLY11 3D protein, SDLY107 3D protein induces slighter cell injury, has weaker effect on cell proliferation activity, and is more favorable for virus replication in cells. Key words: Enterovirus A, human; 3D protein; Cell injury

Health related quality of life on severe hand, foot and mouth disease patients

Objective: To evaluate the health related quality of life (HRQoL) for severe hand, foot and mouth disease (HFMD) patients with different complications. Methods: A national telephone interview under the EQ-5D proxy2 questionnaire (EQ-SD and EQ-VAS), was conducted to obtain the HRQoL of lab-confirmed severe HFMD patients, aged between six months and five-year-olds from the national communicable disease surveillance system from January 1, 2012 to December 31, 2013. Results: A total of 685 severe HFMD cases were included in the study. A total of 456 (66.6%) of them were males with 75.8% of them younger than three years old. A total of 337 (49.2%) and 407 (59.4%) of the participants reported that they had problems in mobility or daily activities. A total of 569 (83.1%) and 616 (89.9%) of the cases reported having problems in pain/discomfort or anxiety/depression. The average EQ-5D and EQ-VAS scores were 0.58±0.23 and 53.6±25.7, both were positively associated with the duration of illness. Mean quality adjusted life years loss during the HFMD episode for the severe patients was (15.45±13.75) years/1 000 persons. The QALY losses for severe patients with each of below complication were: respiratory diseases (11.17±8.83) years/1 000 persons, aseptic meningitis (13.56±11.99) years/1 000 persons, encephalitis/brainstem encephalitis/acute flaccid paralysis (AFP) (15.31±12.63) years/1 000 persons, Myocarditis (17.28±18.16) years/1 000 persons, pulmonary hemorrhage/pulmonary edema (17.34±14.98) years/1 000 persons, cardiopulmonary failure (25.47±20.53) years/1 000 persons. Among patients with lab confirmed Entero virus A71 (EV71) (16.51±14.48) years/1 000 persons, the QALY loss was seen higher than Coxsackie virus A16 (Cox A16) (13.02±11.45) years/1 000 persons and other Enter virus (14.74±14.22) years/1 000 persons (Z=11.83, P=0.003). Conclusion: The HRQoL loss for severe HFMD patients substantially increased under complications exacerbation and related to the duration of illness.

Serum levels of matrix metalloproteinase-3 and autoantibodies related to rheumatoid arthritis in the general Japanese population and their association with osteoporosis and osteoarthritis: the ROAD study.

To purpose of this study was to reveal the mean levels and positive proportion of serological markers related to rheumatoid arthritis, and clarify their relationship with osteoporosis and hand osteoarthritis (OA). A total of 1546 participants from the third survey of the research on osteoarthritis/osteoporosis against disability study were enrolled in the current study. Using participant blood samples, the levels of anti-cyclic citrullinated protein (CCP) antibody, rheumatoid factor (RF), matrix metalloproteinase-3 (MMP-3), C-reactive protein (CRP), and high-sensitivity CRP (hsCRP) were measured. Subjects with higher than normal levels were defined as being positive. Osteoporosis was defined according to the recommendations set by World Health Organization criteria in 1994. Radiographic hand OA was evaluated using the modified Kellgren-Lawrence (KL) scale. The positive proportion of anti-CCP antibody, RF, MMP-3, CRP, and hsCRP was 1.8, 7.1, 15.0, 6.7, and 6.4%, respectively. MMP-3 was associated with age, and was significantly higher in men than in women. Positive MMP-3 was not significantly related to osteoporosis or severe hand OA (KL grade ≥3) after adjustment for other factors including age, sex, and body mass index. The results from this study clarified the values and positive proportion of RA-related markers and revealed their relationship with osteoporosis and hand OA.

ConclusionThe VSD can effectively promote safe and rapid repair of local soft tissues with good prognosis.

Cognitive change trajectories in virally suppressed HIV-infected individuals indicate high prevalence of disease activity.

BackgroundThe longitudinal rate and profile of cognitive decline in persons with stable, treated, and virally suppressed HIV infection is not established. To address this question, the current study quantifies the rate of cognitive decline in a cohort of virally suppressed HIV+ persons using clinically relevant definitions of decline, and determine cognitive trajectories taking into account historical and baseline HAND status.MethodsNinety-six HIV+ (clinically stable and virally undetectable) and 44 demographically comparable HIV- participants underwent standard neuropsychological testing at baseline and 18-months follow-up. We described clinically relevant cognitive trajectories based on standard definitions of historical and baseline HAND status and cognitive decline. Historical, moderate to severe HAND was formally diagnosed at the start of the cART era in 15/96 participants based on clinical neurological and neuropsychological assessment. The same standard of care has been applied to all participants at St. Vincent’s Hospital Infectious Disease Department for the duration of their HIV infection (median of 20 years).ResultsRelative to HIV- controls (4.5%), 14% of HIV+ participants declined (p = .11), they also scored significantly lower on the global change score (p = .03), processing speed (p = .02), and mental flexibility/inhibition (p = .02) domains. Having HAND at baseline significantly predicted cognitive decline at follow up (p = .005). We determined seven clinically relevant cognitive trajectories taking into account whether participant has a history of HAND prior to study entry (yes/no); their results on the baseline assessment (baseline impairment: yes/no) and their results on the 18-month follow up (decline or stable) which in order of prevalence were: 1) No HAND history, no baseline impairment, 18-month follow-up stable (39%), 2) No HAND history, baseline impairment, 18-month follow-up stable (35%), 3) History of HAND; baseline impairment, 18-month follow-up stable (9%) 4) No history of HAND, baseline impairment, 18-month follow-up decline (7%), 5) History of HAND, no baseline impairment, 18-month follow-up stable (3%), 6) No HAND history, no baseline impairment, 18-month follow-up decline (3%) 7) History of HAND, baseline impairment, 18-month follow-up decline (3%). There was no relationship between cognitive decline (taking into account historical and baseline HAND) and traditional HIV disease biomarkers.ConclusionsDespite long-term viral suppression, we found mostly subclinical levels of decline in psychomotor speed and executive functioning (mental flexibility and cognitive inhibition); well-established markers of HAND progression. Moreover, 57% of our cohort is undergoing slow evolution of their disease, challenging the notion of prevalent neurocognitive stability in virally suppressed HIV infection.
