Abstract
OBJECTIVES To investigate the influence of overweight and obesity on general performance and mortality in seniors. DESIGN Cross-sectional multidisciplinary study on ageing of the Polish population. SETTING Community-dwelling individuals aged 65 years or older, selected using three-stage stratified, proportional draw. PARTICIPANTS 4944 Polish Caucasian seniors, aged 65 years or older recruited between October 2007 and October 2010. MEASUREMENTS All study subjects underwent measurement of body mass index (BMI), waist circumference (WC), and arm circumference (AC). The physical and cognitive performance was evaluated using the Katz Activities of Daily Living (ADL) score and Mini-Mental State Examination (MMSE), respectively. Morbidity data were obtained from a medical questionnaire. Mortality data were obtained from the Population Register of Poland between October 2015 and October 2018. RESULTS Increasing age was associated with a decreased prevalence of obesity (all p<0.001). Higher BMI, WC and AC values were associated with higher ADL and MMSE scores (all p<0.001). On multivariate analysis, all three body measurements in women remained independent predictors of the ADL score (BMI p=0.002, WC p=0.005, AC p<0.001) and MMSE score (p<0.001, p=0.003, p<0.001). In men, physical functioning was associated with AC (p=0.003), and cognitive status was associated with AC (p<0.001) and BMI (p=0.013). There was no association between general obesity, abdominal obesity, or AC with several aging-related adverse conditions. Kaplan-Meier survival curves showed that overweight and obesity were associated with the lowest mortality. On multivariate analysis, BMI and AC values remained independent predictors of mortality. In successfully aging individuals, neither BMI, WC, nor AC remained such predictors. CONCLUSIONS Overweight and obesity in Caucasian seniors are not associated with deterioration of physical and cognitive function or with increased mortality.

Abstract
Proximal spinal muscular atrophy (SMA) is classified into three main subtypes (I-III), defined by age at onset and achieved motor milestones. As age at onset can be very early in SMA II and III (IIIa, onset < 3 years) and does not necessarily correlate with prognosis, the question arises whether the child can be correctly assigned to a specific SMA type at the time of presentation based on the assessment of motor function. Therefore we studied the motor milestones in 175 SMA type II and 266 SMA type III patients. In SMA II, 73% of the patients sat within the normal age range (up to 9 months), the remainder learned to do so at ages between 10 and 30 months. In SMA III, the walking milestone was passed with delay (given an upper normal limit of 18 months) in 10% of all and 16% of SMA IIIa patients (median age 13 months, range 9-53 months). There was a correlation between late sitting and walking in SMA III, since those who sat after 9 months were responsible for the majority of delayed walkers. The median age when becoming chairbound did not differ between early-onset SMA III patients who walked with delay and those who walked within the normal age range (10.2 versus 10.5 years). In conclusion, a significant proportion of patients with early-onset SMA classified as SMA II on the basis of achieved motor function turned out to be SMA III at later follow-up. It is important to reassess a child in the first 2-4 years, to determine whether walking can be achieved with or without aids, as children who start to walk late have a similar favourable outcome for ambulation compared to earlier walkers.

Abstract
Mild to moderately elevated creatine kinase (CK) activity is a frequent biochemical finding in proximal spinal muscular atrophy (SMA). In a collaborative study on all types of childhood and juvenile onset SMA, we analysed the CK activity of 504 SMA patients (138 type I, 127 type II, 144 type IIIa, and 95 type IIIb patients). Under the assumption of a lognormal distribution of CK activity as the most appropriate statistical model, CK levels were transformed into logarithms and compared by standard deviation scores = CK-SDS (log). CK activity was statistically different between early and later onset SMA: in SMA I and II, about one-third of patients showed CK-SDS (log) >2 SD, the analysis of the means did not show significant differences. In SMA III, CK-SDS (log) was significantly higher (p < 0.01) than in the two other groups, which was most pronounced in SMA IIIb. More than 90% of SMA IIIb patients showed CK-SDS (log) values >2 vs. 57% in SMA IIIa. As similar values were obtained for a subgroup of 100 patients in whom the diagnosis of autosomal recessive SMA was confirmed by a deletion of the telomeric copy of the survival motor neuron gene, our results can be considered representative for SMA I-III. There was no correlation between CK level and disease duration. The fact that patients were ambulatory or chair-bound had no influence on CK activity in type III SMA. There was no sex influence in SMA I, II and IIIa. The observed higher male values in the group SMA IIIb are most likely the result of a lack of female patients with onset after puberty.

Abstract
We analyzed clinical data of 569 patients in two combined series with childhood and juvenile proximal SMA. This cohort included only patients who had achieved the ability to sit unaided (type II and III SMA). The survival rate among 240 type II patients (who sat but never walked) was 98.5% at 5 years and 68.5% at 25 years. SMA III (n = 329) (those who walked and had symptoms before age 30 years) was subdivided into those with an onset before and after age 3 years (type IIIa, n = 195; SMA IIIb, n = 134). In patients with SMA III, life expectancy is not significantly less than a normal population. The probabilities of being able to walk at 10 years after onset was 70.3%, and at 40 years, 22.0% in SMA IIa. For SMA IIIb, 96.7% were walking 10 years after onset and 58.7% at 40 years. The subdivision of type III SMA was justified by the probability of being ambulatory depending on age at onset; the prognosis differed for those with onset before or after age 3 years. The data provide a reliable basis of the natural history of proximal SMA and support a classification system that is based primarily on age at onset and the achievement of motor milestones.

Abstract
DNA was isolated and analysed in 96 patients with Duchenne or Becker muscular dystrophy (DMD, BMD); 9 of them were affected with BMD. Delections were found in 60 Patients (62.5%) using six cDNA probes. In some cases the PCR technique was also applied. In patients with BMD all deletions but one were in frame and involved exons 45-54. On the contrary, most deletions in DMD were out of frame and varied in their location. In five families prenatal diagnosis was carried out.

Abstract
Emery-Dreifuss muscular dystrophy (EMD) is characterised by (1) early contractures of the Achilles tendons, elbows, and postcervical muscles, (2) slowly progressive muscle wasting and weakness with a predominantly humeroperoneal distribution in the early stages, and (3) cardiomyopathy with conduction defects and risk of sudden death. Inheritance is usually X linked recessive but can be autosomal dominant. Family linkage studies have mapped X linked EMD to the distal long arm of the X chromosome but precise genetic localisation has been hampered by the rarity of this condition. We report three new families with X linked Emery-Dreifuss muscular dystrophy studied with DNA markers from Xq27-qter and three previously published families typed for additional markers. No recombination was observed with the red/green cone pigment locus, RGCP (lod score, Z = 2.46), the factor VIII coagulant gene locus, F8C (Z = 6.39), or with DXS115 (Z = 4.94). Two recombinants were observed which mapped EMD distal to DXS15 (DX13) and DXS52 (St14) respectively. Multipoint linkage analysis gave odds exceeding 200:1 for EMD being distal to these markers. A multipoint analysis incorporating published data gave the map cen-DXS304-9cM-DXS15-3cM-DXS52-2 cM-(RGCP,EMD)-3cM-F8C-2cM-DXS115 with odds of 120:1 in favour of a location for EMD between DXS52 and F8C as compared to the next best position distal to F8C.

Abstract
This study provides epidemiological data on acute infantile (ASMA) and chronic childhood spinal (CSMA) muscular atrophy in Warsaw for the period 1976-1985. All calculations are based on the assumption that ASMA and CSMA result from mutations at two different gene loci. The incidence of ASMA and CSMA was 1 in 19474 live births with a corresponding gene and carrier frequency of 714 x 10(-5) and 1 in 70, respectively. The prevalence of CSMA for the year 1985 was 1.26 x 10(-5). These figures are higher than in similar studies in other countries. This fact might be connected with the careful ascertainment in this study.

Abstract
The proportion of sporadic cases of Duchenne muscular dystrophy has been estimated by classical segregation analysis in a pooled sample of 1885 sibships from 7 different countries. A significant departure from the theoretical expectations based on mutation-selection equilibrium is observed (segregation frequency = 0.439 +/- 0.017; frequency of sporadic cases = 0.229 +/- 0.026, at the maximum likelihood). The occurrence of germinal mosaicism in some of the mothers of Duchenne cases may account for this peculiar finding, although a possible role of inequality of mutation rates in the two sexes cannot be ruled out.

Abstract
A series of 95 families, consisting of 317 patients with severe and mild X-linked proximal pseudohypertrophic muscular dystrophy (MD), was analysed by the use of two different and rigid clinical criteria based on the age when the patient became chairbound. Using these criteria the families from Erfurt and Warsaw could be clearly separated into classical Duchenne (DMD) and classical Becker (BMD) type patients. A third group of patients was found with atypical clinical course, who could not be identified as neither Duchenne nor Becker cases. Statistically highly significant differences were found between the groups of classical DMD and atypical MD cases on the one hand and between the groups of atypical MD and classical BMD cases on the other, especially with respect to age when chairbound and age at death. The comparisons of progression of the disease, life expectancy and of fertility between the three groups of X-linked MD show that classical DMD and atypical MD may be considered as separate types of severe X-linked proximal pseudohypertrophic MD. On the basis of these findings the authors offer conclusions for the general practice of neurology, paediatrics and genetic counseling.

Abstract
We used probes for DNA polymorphisms on the X chromosome to study genetic linkage in seven families with X-linked adult-onset spinal muscular atrophy. We found significant linkage to the marker DXYS1 on the proximal X chromosome long arm and loose linkage or nonlinkage to markers elsewhere. Our analysis localizes the gene defect for this form of anterior horn cell disease.

Abstract
Two families with Emery-Dreifuss muscular dystrophy (EMD) have been studied with DNA markers mapping to Xq27.3----qter. No recombination was observed in 11 phase known meioses informative for the factor VIII gene (F8C) and eight phase known meioses informative for DXS15 (DX13), giving maximum lod scores of 3.50 and 2.50 respectively at a recombination fraction of zero. DXS52 (St14) showed one recombinant in 12 phase known meioses giving a maximum lod score of 2.62 at a recombination fraction of 0.07. These results map EMD to the distal end of the long arm of the X chromosome and are an important step in the development of tests for carrier detection and prenatal diagnosis.

Abstract
Results obtained from a study of 354 cases of chronic proximal spinal muscular atrophy of childhood and adolescence suggest that the condition is not as homogeneous as it was previously thought. A tentative classification based on our results is proposed. Estimates of genetic risks are provided, taking into account the sex and age at clinical onset. In our opinion these factors are more reliable than the data hitherto available because they are based on a considerably larger series.

Abstract
Segregation analysis was performed on 354 cases of chronic proximal spinal muscular atrophy of childhood and adolescence (CPSMA) in the total series and in a number of subgroups formed according to the age at onset and sex. The analysis provided evidence of sex influence in the series studied, particularly in a subgroup of the milder form of the disease with onset between the 37th month and 18th year of life. In the latter subgroup, females were affected much less frequently. This was particularly striking after age at onset of 8 years, and only exceptionally were females affected after the age of 13 years. These facts point to incomplete penetrance of the gene.

Abstract
Neurological and endocrinological studies were carried out in 8 of 12 male patients with X-linked spinal muscular atrophy. In six investigated cases, gynaecomastia was discovered. First muscle symptoms started between 21 and 44 years of age, at which time the patients observed disturbances in their sexual life. In three cases decreased fertility and in two cases sterility was reported. Diagnostic testicular biopsy showed pronounced involutional changes of the Leydig cells. The plasma testosterone level was decreased, while the levels of luteinizing hormone and prolactine were normal, and the follicle stimulating hormone was at a high normal level. The dexamethasone/human chorionic gonadotrophin test revealed a pronounced decrease in the functional reserve of the Leydig cells. It is suggested that all these anomalies are connected with an increased ratio of oestrogen to androgen level.

Abstract
The results of an analysis of a group of 250 patients with acute and mild forms of x-linked dystrophy and of 184 women from their families seem to suggest a similar genetic defect in both forms of the disease. The posibility of intrafamilial variability, similar type of muscular damage and indentical features of heterozygotes may support this hypothesis. This may suggest also a practical conclusion for genetic counselling, that it is difficult to predict reliably what wall be the form of the disease in the sons of a female carrier of dystrophy gene.

Abstract
The authors discuss the differences between the two large series of chronic childhood spinal muscular atrophies (SMA)--their own comprising 273 cases, and that of Pearn et al. comprising 141 cases. The main difference concerns the predominance of males in the clinically milder later-onset group in the present series. The data of Pearn et al. (1978a, b) are quite different. The reason for the discrepancies is apparently a different selection of material. The present material is highly selective in favour of chronic cases, and Kugelberg-Welander cases are well-represented, whereas the percentage of Kugelberg-Welander cases in the material of Pearn et al. was very small. Differences in selection also appear to be responsible for discordance in observations regarding influence of sex on the course of the disease. The present data seem to support the view that most of the cases revealing chronic forms of SMA (both mild and severe) are not distinct genetically. However, the possible existence of a distinct subgroup in which sex influence is strongly expressed is not excluded.

Four of five afflicted boys in the family K. suffer from the Becker type of dystrophy and one from a more severe type. All affected boys and their mothers, who are three sisters, have undergone clinical, electromyographic, electrocardiographic and biochemical examination; muscle biopsy was performed in some boys. This family is a rare example of the intrafamilial variability of X-linked progressive muscular dystrophy. The possible explanation of the variability observed is discussed.

Abstract
A material of 247 cases selected from 260 cases of spinal muscular atrophy in the Warsaw Department of Neurology in 1960-1974 was analyzed. The size of sibships was established and calculations were made of the mean distribution of the age at onset, also according to sex, for the different clinical forms, genetical proportions by the method of siblings and of probands, and coefficient of sib-sib correlation for the material as a whole and separately for males, females and male-female pairs. The analysis shows the course of the disease to differ between the sexes and to be mild in males more often than in females, as is particularly noticeable in the higher age groups. Cases of Kugelberg-Welander's disease are predominantly male. The hypothesis is advanced that a proportion of male patients have a sex-linked modifying gene of a fairly high frequency (possibly of the range of 1 in 5 males, and 1 in 25, in the homozygous state, in females). Although it would not disprove conclusively the nosological distinctness of different forms of infantile and juvenile spinal muscular atrophy, the existence of the modifying gene, if proved, would tend rather to add to the likelihood of their constituting a single recessive autosomal disease.

Abstract
There is considerable variation in age of onset, though in over three-quarters of cases onset is before 4 years of age. A febrile episode, often of viral origin, may be present at the time of onset and might possibly be of aetiological significance, perhaps by precipitating the disease in a genetically predisposed individual. Reduced fetal movements and floopiness at birth are present in about one third of those cases where the onset is in early childhood. It would seem that when the onset is before 4 years of age, and particularly if the child has never been able to sit without support, the prognosis is much worse than in cases where the onset is after the age of 4 years. The proximal limb muscles are predominantly affected and muscle tone is usually reduced but pseudohypertrophy is uncommon. Rarely are the cranial nerves affected. Muscle fasiculations are present in about half the cases. Almost 10% of cases appear to be mentally retarded. With regard to the EMG findings, spontaneous activity, reduced full effort pattern increased potential amplitude and duration and increased motor unit territory appear to be the most reliable diagnostic criteria. Routine histological evidence of neurogenic atrophy seems to be a more reliable diagnostic criterion than muscle histochemistry. However, this may be only reflect the way in which the data were selected, that is, from cases where a muscle biopsy showed evidence of neurogenic atrophy on routine histology. Finally the serum level of creatine kinase is rarely very high and in more than half the cases it is normal. The CSF chemistry is always normal.
