Effects of Growth Hormone Treatment on Height, Weight, and Obesity in Taiwanese Patients with Prader-Willi Syndrome
BackgroundInformation regarding the efficacy of growth hormone (GH) therapy in Asian Prader-Willi syndrome (PWS) patients is lacking. We report our experience with GH treatment in children with PWS in Taiwan.MethodsForty-six PWS patients (27 males, 19 females; age range, 1 year 4 months to 13 years 7 months) who received and/or who are currently receiving GH treatment (0.1 IU/kg/day subcutaneously) for a period from 1 year to 3 years were retro-spectively analyzed. We evaluated height, weight, body mass index (BMI) and Rohrer index, before and after GH treatment.ResultsAfter patients had received GH for 1, 2 and 3 years, a significant improvement in mean height standard deviation score (SDS) was noted from −1.24 to −0.31 (p <0.01), 0.00 (p <0.001) and −0.26 (p <0.001), respectively. Mean BMI SDS decreased significantly from 1.93 to 1.13 (p <0.05) after 1 year of treatment; however, no significant changes were observed afterward. Mean Rohrer index decreased significantly, from 224.2 to 186.6 (p <0.001), 178.9 (p <0.001) and 169.3 (p <0.001). No significant gender or genotype pattern differences were noted among the 4 parameters examined.ConclusionThis 3-year, retrospective study indicates that PWS patients benefit from GH therapy in height increase and improved body composition
The risk of false inclusion of a relative in parentage testing – an in silico population study
Aim To investigate the potential of false inclusion of a
close genetic relative in paternity testing by using computer
generated families.
Methods 10 000 computer-simulated families over three
generations were generated based on genotypes using 15
short tandem repeat loci. These data were used in assessing
the probability of inclusion or exclusion of paternity
when the father is actually a sibling, grandparent, uncle,
half sibling, cousin, or a random male. Further, we considered
a duo case where the mother’s DNA type was not
available and a trio case including the mother’s profile.
Results The data showed that the duo scenario had the
highest and lowest false inclusion rates when considering
a sibling (19.03 ± 0.77%) and a cousin (0.51 ± 0.14%) as
the father, respectively; and the rate when considering a
random male was much lower (0.04 ± 0.04%). The situation
altered slightly with a trio case where the highest rate
(0.56 ± 0.15%) occurred when a paternal uncle was considered
as the father, and the lowest rate (0.03 ± 0.03%) occurred
when a cousin was considered as the father. We also
report on the distribution of the numbers for non-conformity
(non-matching loci) where the father is a close genetic
relative.
Conclusions The results highlight the risk of false inclusion
in parentage testing. These data provide a valuable
reference when incorporating either a mutation in the father’s
DNA type or if a close relative is included as being
the father; particularly when there are varying numbers of
non-matching loci
Persistent surgical wound bleeding: A rare condition related to acquired hemophilia A
SummaryAcquired hemophilia A (AHA) is a rare condition that predisposes affected patients to a bleeding tendency, even after a trivial physical insult. We present our experience with a 45-year-old male patient who was referred to our institute because of persistent bleeding from a left forearm surgical wound after fasciotomy. He was diagnosed as having AHA. Surgical treatment in combination with recombinant activated factor VII (rFVIIa) led to a satisfactory result. Clinical awareness and multidisciplinary professional connections are necessary in the treatment of AHA. Acquired hemophilia should be considered in the differential diagnosis of patients with uncontrolled bleeding episodes
A novel strategy for sibship determination in trio sibling model
Aim To use a virtually simulated population, generated
from published allele frequencies based on 15 short tandem
repeats (STR), to evaluate the efficacy of trio sibship
testing and sibling assignment for forensic purposes.
Methods Virtual populations were generated using 15 STR
loci to create a large number of related and unrelated genotypes
(10 000 trio combinations). Using these virtual populations,
the probability of related and unrelated profiles
can be compared to determine the chance of inclusions
of being siblings if they are true siblings and the chance of
inclusion if they are unrelated. Two specific relationships
were tested – two reference siblings were compared to a
third true sibling (3S trio, sibling trio) and two reference siblings
were compared to an unrelated individual (2S1U trio,
non-sibling trio).
Results When the likelihood ratio was greater than 1,
99.87% of siblings in the 3S trio population were considered
as siblings (sensitivity); 99.88% of non-siblings in the
2S1U trio population were considered as non-siblings
(specificity); 99.9% of both populations were identified correctly
as siblings and non-siblings; and the accuracy of the
test was 99.88%.
Conclusions The high sensitivity and specificity figures
when using two known siblings compared to a putative
sibling are significantly greater than when using only one
known relative. The data also support the use of increasing
number of loci allowing for greater confidence in genetic
identification. The system established in this study could
be used as the model for evaluating and simulating the
cases with multiple relatives
The effectiveness of adjunct mindfulness-based intervention in treatment of bipolar disorder: A systematic review and meta-analysis
BACKGROUND: Mindfulness-based interventions (MBIs) have been increasingly used as an adjunctive treatment to pharmacotherapy for a few psychiatric disorders. However, few studies have investigated the efficacy of MBIs in bipolar disorder (BD). METHODS: We performed a systematic review and meta-analysis to evaluate the efficacy of MBIs as an adjunctive treatment in BD. Major electronic databases were independently searched by two authors for controlled and uncontrolled studies which examined the effects of MBIs on psychiatric symptoms in subjects with BD. Data from original studies were synthesized by using a random effects model. RESULTS: Twelve trials were eligible for inclusion into current meta-analysis, including three controlled studies (n=132) and nine uncontrolled studies (n=142). In within-group analysis, MBIs significantly reduced depressive (7 studies, n=100, Hedges' g=0.58, p<0.001) and anxiety (4 studies, n=68, Hedges' g=0.34, p=0.043) symptoms, but not manic symptoms (6 studies, n=89, Hedges' g=0.09, p=0.488) and cognition (3 studies, n=43, Hedges' g=0.35, p=0.171), compared to baseline. In between-group analysis (intervention group versus waiting list group, all patients with BD), MBIs did not reduce depressive (3 studies, n=132, Hedges' g=0.46, p=0.315) or anxiety (3 studies, n=132, Hedges' g=0.33, p=0.578) symptoms. LIMITATIONS: Only three controlled trials compared MBIs to control conditions. CONCLUSIONS: Our meta-analysis showed significantly beneficial effects on depressive and anxiety symptoms of BD patients in within-group analysis. However, this significance was not observed in comparison with the control groups. Further clinical trials are warranted to investigate the differences in the benefits of MBIs between treatment and control subjects
