NEW YORK – A small pilot study has shown that patients with Parkinson’s disease who participated in the Rock Steady Boxing non-contact training program may have faster reaction times than PD patients who did not participate in the program, according to a poster presented at the International Conference on Parkinson’s Disease and Movement Disorders.

“The novelty of this is that it shows how Rock Steady Boxing and exercise programs that use sequences and the learning of sequences could possibly help slow the decline, or maintain a level of functioning longer, in Parkinson’s disease,” said Christopher McLeod, a second-year medical student at New York Institute of Technology (NYIT) College of Osteopathic Medicine, Old Westbury, N.Y.

Rock Steady Boxing is a non-contact program tailored to Parkinson’s patients founded in 2006 by Scott Newman, an Indiana lawyer who was diagnosed with early onset Parkinson’s at age 40. The regimen involves intense one-on-one training centered around boxing. Rock Steady Boxing offers classes from coast to coast in the United States and in 13 other countries. Mr. McLeod is a volunteer at the NYIT chapter of Rock Steady Boxing in Old Westbury, N.Y.

Mr. McLeod studied 28 PD patients – 14 who had been taking Rock Steady Boxing classes at NYIT for at least 6 months and 14 controls. The goal of the study was to evaluate if the Rock Steady Boxing participants showed any improvement in procedural motor learning. His coauthor was Adena Leder, DO, a faculty neurologist and movement disorder specialist at NYIT,

“What’s new about this research is the procedural memory component and the Rock Steady Boxing program is just more of the vessel, so to speak,” Mr. McLeod said. “This is a pilot study. We wanted to see if Rock Steady Boxing would show benefits in these patients. There are some trends in my research that [indicate] it would; it did not have statistical significance, but we did see trend lines.”

The researchers used a modified Serial Reaction Time Test (SRTT) composed of seven blocks of 10 stimuli each with 30-second breaks between blocks. Blocks consisted of a random familiarization block, four learning blocks repeating the same sequence of stimuli, a transfer block of random stimuli, and a posttransfer block presenting the same sequence of stimuli from the four learning blocks.

They assessed procedural learning by comparing the reduction in response time over the four identical learning blocks as well as by comparing changes in response time when the subjects were subsequently exposed to the random transfer block.

Experienced boxers demonstrated faster reaction time over the four learning blocks, ranging from 795.32 vs. 906.89 ms in the first learning block to 674.79 vs. 787.32 ms in the fourth learning block (P = .19). In the random sequence transfer block, controls showed a 93.5-ms decrease in median reaction time vs. a 27.3-ms increase in reaction time of experienced boxers. One possible explanation the investigators noted is that the controls simply got better at reading the stimuli over time without actually learning the repeated sequence.

Mr. McLeod noted that a typical Rock Steady Boxing session starts with a warmup and stretch, then learning the boxing stance with the nondominant foot back, shoulders over the body and the head over the feet. The boxing moves involve sequences of different punching combinations — jab, jab, cross; left, left, right; jab, cross, hook. Then the class divides into separate circuits for boxing and exercise. The boxing circuit involves punching the speed bag – the small, air-filled, pear-shaped bag attached to a hook at eye level – as well as heavy bag and partner-held focus mitts, all with the aim of reinforcing the learned sequences. The exercise circuit focuses on muscle training and exercise with the goal of improving balance and gait.

“The boxing sequences help not only with cognitive ability but motor control,” Mr. McLeod said. “The program also helps with some of the nonmotor aspects of Parkinson’s disease. Depression is almost synonymous with Parkinson’s disease; this brings people together and builds camaraderie.”

Mr. McLeod said he hopes the research continues. “I’m hoping that this can be a jumping-off point for research going forward with procedural memory, Parkinson’s, and Rock Steady Boxing or programs like it,” he said. Future research should involve more subjects, measure improvement within same subjects who participate in the program, and account for variables such as age and gender.

Mr. McLeod and Dr. Leder reported having no relevant financial disclosures.

Bleeding scores may be helpful in identifying hemophilia patients, regardless of whether or not clotting factor levels are known, results of a recent investigation suggest.

Both hemophilia A and B patients had significantly higher bleeding scores as assessed by the ISTH-BAT (International Society on Thrombosis and Hemostasis–Bleeding Assessment Tool), compared with control subjects, according to results of the study.

Moreover, hemophilia patients classified as severe had significantly higher ISTH-BAT scores compared with those classified as mild, reported by Munira Borhany, MD, of the National Institute of Blood Disease and Bone Marrow Transplantation, Karachi, Pakistan, and her colleagues.

“The ISTH-BAT can be easily used in the clinics by physicians and can help to identify those patients who should be further investigated,” Dr. Borhany and her coauthors reported in the journal Transfusion and Apheresis Science.

The ISTH-BAT, established to standardize the reporting of bleeding symptoms, scores symptoms from 0, which indicates absent or trivial, to 4, meaning a symptom that requires medical intervention. Total scores considered abnormal are 4 or greater in men, 6 and greater in women, and 3 and greater in children, according to previously published reports.

In the present cross-sectional study, Dr. Borhany and her colleagues evaluated bleeding scores for 115 adult and pediatric patients – 78 with hemophilia A and 37 with hemophilia B – who were treated in Pakistan between 2014 and 2016.

Bleeding scores were a mean of 13.5 and 13.2 for hemophilia A and B patients, respectively, and 0.8 for 100 healthy male controls also included in the study. Scores were significantly higher in hemophilia patients versus controls (P less than .001), but not different between hemophilia A and B patients, the investigators reported.

Further results suggested a correlation between factor levels and clinical presentation of bleeding symptoms, according to the investigators. Statistically significant differences in bleeding scores also were seen between patients with severe and mild disease, and between severe and moderate disease, but not between the mild and moderate groups, they added.

Most studies of bleeding questionnaires to date have been in patients with von Willebrand disease or platelet disorders, with very little data on hemophilia.

“Apart from one recent study using ISTH-BAT in hemophilia carriers as part of assessing quality of life, we are unaware of other studies examining this assessment tool in hemophilia,” the researchers wrote.

This study cohort was unique, according to the investigators, because it included a substantial number of adults who were new patients with bleeding symptoms who had no previous diagnosis of hemophilia. “This allowed assessing whether investigators may tend to apply a higher score when knowing very low factor levels in hemophilia patients,” they said.

In fact, there was no major difference in bleeding scores for those newly diagnosed patients versus already diagnosed patients.

Results of an ongoing study will determine whether the ISTH BAT bleeding score can predict risk of bleeding in hemophilia patients, according to Dr. Borhany and her coauthors.

They reported having no conflicts of interest.

Patients with psoriasis and hypertension are at a higher risk of having to undergo cardiovascular procedures and surgery, compared with patients with hypertension alone.

“The results suggested that hypertensive patients with concurrent psoriasis experienced an earlier and more aggressive disease progression of hypertension, compared with general hypertensive patients,” Hsien-Yi Chiu, MD, PhD, from the department of dermatology at the National Taiwan University Hospital in Hsinchu, Taiwan, and his colleagues wrote in the Journal of Dermatology. “Thus, patients with hypertension and psoriasis should be considered for more aggressive strategies for prevention of primary [cardiovascular disease] and more intense assessments for cardiovascular interventions needed to improve [cardiovascular disease] outcome in these patients.”

They performed a nationwide cohort study of patients in the Taiwan National Health Insurance Research Database with new onset hypertension from 2005 to 2006. Those with psoriasis (4,039 patients) were matched by age and sex to patients in the database who were diagnosed with hypertension but not psoriasis; the mean follow-up was 5.62 years. Their mean age was 58 years and about 31% of the psoriasis cohort were female. They were divided into groups based on psoriasis severity (mild and severe psoriasis) and type (psoriasis with and without arthritis). Researchers noted patients with both psoriasis and hypertension also had higher rates of cerebrovascular disease, coronary heart disease, hyperlipidemia, and diabetes mellitus during the year prior to the study.

The outcome measured was having a cardiovascular procedure (percutaneous coronary intervention with/without stenting or percutaneous transluminal coronary angioplasty and transcatheter radiofrequency ablation for arrhythmia) and cardiovascular surgery (coronary artery bypass grafting and other surgery for heart valves, arrhythmia, cerebrovascular disease, peripheral vessels, and the aorta).

Patients with both psoriasis and hypertension were at an increased risk for having a cardiovascular procedure and surgery (adjusted hazard ratio, 1.28; 95% confidence interval, 1.07-1.53), compared with patients with only hypertension. The risk of this outcome was also increased among patients with severe psoriasis or psoriatic arthritis, compared with patients who had mild psoriasis (aHR, 1.22; 95% CI, 0.98-1.51) and with patients with psoriasis but not arthritis (aHR, 1.15; 95% CI, 0.84-1.58); however, the results did not reach statistical significance after adjustment, which the researchers attributed to the small subgroup size.


“Another possible explanation was that the observed increased requirement for cardiovascular procedure and surgery in patients with severe psoriasis was mediated by a complex interplay among inflammation, traditional risk factors for [cardiovascular disease], and antirheumatic drugs, which probably attenuate the effects conferred by psoriasis,” the authors wrote.

Limitations in the study included reliance on administrative claims data for psoriasis diagnosis, unavailability of some details of the cardiovascular procedures and surgery, lack of blood pressure data to identify hypertension severity, as well as unmeasured factors and confounders. Further, “comparative occurrence of a requirement for cardiovascular procedure and surgery in the two groups may be influenced by a competing risk for death,” the researchers noted.
