ABSTRACT

BACKGROUND: Sexual health is an integral part of overall health in older age. Research consistently reports that heterosexual and queer older people tend not to disclose sexual concerns and difficulties which increases the risks for sexually transmitted diseases. Older people are often absent from policies and information programmes and healthcare providers experience difficulties in initiating conversations around sexual health and history. OBJECTIVES: To identify what are the barriers that stop older people seeking sexual health advice and treatment. DESIGN AND METHOD: A scoping review methodology was employed. Published and unpublished literature was scoped through development of a research question, identification of potentially relevant studies, selection of relevant studies using an iterative team approach, charting data, collating, summarising and reporting findings, and considering the implications of study findings for further research. DATA SOURCES: Electronic databases searches were run to identify published and unpublished literature, including Medline, Embase, PsycINFO, CINAHL, ASSIA, Social Sciences, RCN and Cochrane Libraries. Additional studies were located through hand searching. RESULTS: Twelve studies from: the USA (n = 6); the UK (n = 3); Australia (n = 2); and one shared paper between New Zealand and UK met the inclusion criteria. Four barriers that stop older people seeking sexual health advice and treatment were identified, including (1) Cultural and societal views and beliefs toward sexual health; (2) Stigma, embarrassment and discrimination; (3) Lack of education and training of healthcare professionals; (4) Quality of relationship between patients and health professionals. CONCLUSION: Barriers to seeking and receiving advice and treatment for sexual health in later life clearly exist and are both related to cultural and social factors. Overall, the papers reviewed in this scoping review indicate that healthcare providers are reluctant to initiate conversations around sexual health or offer appropriate advice or clinical tests, and that older people tend to be hesitant to seek medical help. Later life age groups independently from their sexual orientation represent a hidden population and are absent from sexual health campaigns and government policies. Efforts need to be made by influential institutions and healthcare providers to recognise sexuality in older age and give older people the opportunity to open up regarding their sexual health and experiences.

ABSTRACT

We present a mass map reconstructed from weak gravitational lensing shear measurements over 139 deg2 from the Dark Energy Survey science verification data. The mass map probes both luminous and dark matter, thus providing a tool for studying cosmology. We find good agreement between the mass map and the distribution of massive galaxy clusters identified using a red-sequence cluster finder. Potential candidates for superclusters and voids are identified using these maps. We measure the cross-correlation between the mass map and a magnitude-limited foreground galaxy sample and find a detection at the 6.8σ level with 20 arc min smoothing. These measurements are consistent with simulated galaxy catalogs based on N-body simulations from a cold dark matter model with a cosmological constant. This suggests low systematics uncertainties in the map. We summarize our key findings in this Letter; the detailed methodology and tests for systematics are presented in a companion paper.

ABSTRACT

Growth and skeletal maturation are impaired in sickle cell disease (SCD). SCD is also associated with decreased bone mineral density (BMD) as determined by dual X-ray and photon absorptiometry. Quantitative ultrasound (US), which is as good a predictor of fracture as absorptiometry, provides additional information about bone architecture and elasticity. It is not known if the quantitative US parameters, broadband ultrasound attenuation (BUA) and speed of sound (SOS), are affected in children and adolescents with SCD. We therefore compared the bones of 80 children with SCD in Nigeria to those of age- and gender-matched controls using calcaneal ultrasound and the serum bone markers N-telopeptide of type1 collagen (NTx) and bone-specific alkaline phosphatase (BSAP), which are indicators of bone resorption and formation, respectively. BUA, which is reflective of BMD, was significantly lower for both the male and female SCD subjects compared with controls (86 vs 113 dB/MHz, P < 0.001 and 87 vs 100 dB/MHz, P < 0.001, respectively). However, SOS, which is more indicative of bone elasticity, was significantly different only for the male SCD subjects. Both NTx and BSAP were significantly reduced in the serum of the male and female SCD subjects. Correlations between BUA and serum NTx were found for both female controls and SCD subjects (r = 0.58, P < 0.001 and r = 0.32, P = 0.05, respectively), but not for the male subjects or controls. Significant correlations between BUA and BSAP were observed only for the female controls. In summary, we have shown that US analysis, in combination with serum markers of bone metabolism, can be used to distinguish bone development in children with SCD from that of nonaffected controls.

ABSTRACT

Phase angle, an impedance parameter used for nutritional assessment, is reflective of the capacitance properties of cell membranes. We have shown a significant correlation between the proportions of specific n-3 polyunsaturated fatty acids in the serum phospholipids of Nigerian children with sickle cell disease and their phase angles determined by bioelectrical impedance analysis.

ABSTRACT

When chronically exposed to ultraviolet radiation (UV), opossums of the species Monodelphis domestica develop corneal sarcomas at high frequency. Post-UV exposure to photoreactivating light enhances repair of UV-induced pyrimidine dimers and suppresses, but does not abrogate, corneal tumor development. We compared mutation spectra in ras and p53 genes in 32 eye tumors from Monodelphis exposed to UV alone and in 25 tumors from Monodelphis exposed to UV followed by photoreactivation in order to identify the particular types of mutation suppressed by enhanced repair of pyrimidine dimers. Mutations were detected by polymerase chain reaction amplification followed by direct sequencing or by "cold" single-strand conformational polymorphism analysis. The overall frequency of mutations was low, and there was no statistically significant difference between the two groups of tumors in the frequency or type of mutation. All mutations occurred at dipyrimidine sites, and most were C to T or CC to TT mutations, the hallmark UV-induced mutations. Hotspots of p53 mutation identified in a previous study of invasive tumors were absent, and mutations identified in the present study included synonymous mutations not previously detected. The difference in stage of the tumors examined is believed to account for these differences. The preponderance of signature UV mutations in p53 and ras genes confirm that UV is the proximate carcinogen for these tumors. The low incidence of mutations suggest that neither ras activation nor p53 inactivation is essential for tumor formation. Mutations attributable specifically to pyrimidine dimer formation could not be identified.

ABSTRACT

Adenophostin A possesses the highest known affinity for the inositol 1,4,5-trisphosphate (Ins(1,4,5)P3) receptor (InsP3R). The compound shares with Ins(1,4,5)P3 those structural elements essential for binding to the InsP3R. However, its adenosine 2'-phosphate moiety has no counterpart in the Ins(1,4,5)P3 molecule. To determine whether its unique structure conferred a distinctive biological activity, we characterized the adenophostin-induced Ca2+ signal in Xenopus oocytes using the Ca2+-gated Cl- current assay. In high concentrations, adenophostin A released Ca2+ from Ins(1,4, 5)P3-sensitive stores and stimulated a Cl- current that depended upon the presence of extracellular Ca2+. We used this Cl- current as a marker of Ca2+ influx. In low concentrations, however, adenophostin A stimulated Ca2+ influx exclusively. In contrast, Ins(1,4,5)P3 and (2-hydroxyethyl)-alpha-D-glucopyranoside 2',3, 4-trisphosphate, an adenophostin A mimic lacking most of the adenosine moiety, always released intracellular Ca2+ before causing Ca2+ influx. Ins(1,4,5)P3 could still release Ca2+ during adenophostin A-induced Ca2+ influx, confirming that the Ins(1,4, 5)P3-sensitive intracellular Ca2+ stores had not been emptied. Adenophostin- and Ins(1,4,5)P3-induced Ca2+ influx were not additive, suggesting that both agonists stimulated a common Ca2+ entry pathway. Heparin, which blocks binding to the InsP3R, prevented adenophostin-induced Ca2+ influx. These data indicate that adenophostin A can stimulate the influx of Ca2+ across the plasma membrane without inevitably emptying the Ins(1,4,5)P3-sensitive intracellular Ca2+ stores.

ABSTRACT

The clarity of the speech of 12 speakers was assessed by intelligibility tests with hearing impaired subjects and from self-ratings about the speaker's ability to communicate with such listeners. The results of these tests correlate positively. Self-ratings account for approximately 60% of the variance. Thus self-ratings can be used as a convenient practical way of establishing an individual speaker's clarity.

ABSTRACT

Ninety patients who were Jehovah's Witnesses underwent 107 total hip replacements without transfusion; all procedures were performed under spinal anesthesia. Of these 90, 87 had not previously undergone hip replacement surgery. They sustained an average intraoperative blood loss of 300 mL, which was a significant reduction compared with that in controlled groups of patients reported by other authors. Factors other than spinal anesthesia that aided in reducing blood loss were posterior surgical exposure of the hip without capsulectomy or removal of the greater trochanter, hemostasis without electrocauterization, and rapidly performed surgery. There were three operative complications and one death, none of which were related to spinal anesthesia.

ABSTRACT

Nineteen scoliotic patients were treated with the standard Harrington distraction rod supplemented with transverse traction. The latter consists of a compressive device (either Harrington';s or Cotrel's) applied to the convex side of the curve to correct disc space wedging and then drawn toward the distraction rod with a simple traction apparatus. Intraoperative roentgenograms were taken with the Harrington distraction rod alone after maximal distraction was applied. This was followed by postoperative roentgenograms with the transverse traction added. The 50.3% correction by distraction rod alone is increased to 66% with the addition of transverse traction. Detailed analysis of each curve, segment by segment, showed that the correction was augmented, not only in the center of the curve, where the compression corrected disc space wedging, but in the ends of the curve as well. This series uses each patient as his or her own control in demonstrating increased correction added by transverse traction.

ABSTRACT

Spinal fusion was performed in 23 patients with congenital scoliosis. Various procedures were used including posterior fusion and without instrumentation. No surgical procedure proved to be superior for obtaining correction regardless of the use of supplemental instrumentation. The use of Knodt or Harrington Instrumentation could not be correlated with a lower pseudoarthrosis rate, shorter postoperative immunobilization period, or a decrease in postoperative loss of correction. The morbidity associated with these surgical procedures was high (48%). Thoracic curves were more prone to lengthen or develop kyphoses postoperatively. A high incidence of varied congenital anomalies was found in association with congenital scoliosis. A through work-up including an intravenous pyelogram and myelogram is strongly recommended prior to the operative treatment of congenital scoliosis.

ABSTRACT

There has been little mention in the literature of scoliosis associated with osteogenesis imperfecta. The purpose of this study was to investigate the problem of spine deformity in a series of osteogenesis imperfecta patients and to review the operative treatment of 8 patients. A series of 49 patients (ranging in age from 8 months to 57 years, average 12 years) with osteogenesis imperfecta were studied. Thirty-five (71%) of these patients had scoliosis ranging from 7 degrees to 105 degrees (average 42 degrees). The more severely involved patients (OIC and OITI groups) demenostrated a higher incidence (80%) of scoliosis and a greater average degree of curvature (42 degrees) as compared to the mildly involved (OITII) group with a 50% incidence of scoliosis with an average curvature of 26 degrees. Attempts to control these curves by bracing have been difficult and usually had to be abandoned. Eight of these patients underwent spine stabilization in an attempt to control curve progression. All 8 patients had posterior spine fusions. One of these patients had an anterior fusion preceding the posterior fusion because of a significant kyphotic deformity. Harrington instrumentation was used in 5 patients. One patient could not be instrumented secondary to severe osteoporosis while the remaining 2 patients were treated by the Risser technique. Postoperatively, either cast or brace protection was used. Only minimal improvement in the curves was achieved. Spine stabilization rather than curve correction is the goal of spine fusion in osteogenesis imperfecta. An important finding was that there was no change in the pre- and postoperative activity and ambulatory status in these patients. Preliminary follow-up (9-12 months) in all 8

ABSTRACT

An intact segment of autologous fibula provides a strong, physiologic, anterior support in the surgical treatment of short segment kyphosis. In this series of 20 patients, only 3 had no signs of spinal cord injury. Correction averaged 20 degrees. At an average follow-up of 2.2 years, 9 degress of the previously obtained correction were maintained, including 3 patients with non-union and marked loss of correction. Twenty-four complications were noted in association with traction, surgery, and immobilization. The results suggest that attempts at correction should remain secondary to those of stabilization and relief or prevention of neurologic problems. Supplementary posterior spinal fusion is necessary to increase the strength of the stabilized segment as well as decrease the incidence of pseudoarthrosis and loss of correction.

ABSTRACT

Of 41 patients with Duchenne muscular dystrophy, no ambulatory patient had scoliosis greater than 19 degrees. Non-ambulatory patients were prophylactically placed in body jackets, which kept the spine flexible and provided adequate support for sitting in the majority of patients. Ten patients had posterior spine fusion for progressive spinal collapse. The procedure was extensive with significant blood loss but boney fusion was achieved in every case. Pulmonary complications were minimized by performing preoperative tracheostomy on all patients who had vital capacities less than 40% and or non-functional coughs. Spinal fusion permitted long-term sitting stability despite the progression of the disease.

ABSTRACT

Eighty-one patients (116 clubfeet) underwent posterior ankle release before the age of two years, following unsatisfactory responses to serial corrective casts applied according to the technique of Kite. Seventy-three per cent of these feet showed no or only mild talar flattening at an average follow-up of 7.5 years. Four years, following posterior ankle release there was a none-mild talar flattening rate of 69 per cent in this group compared to a 40 per cent none-mild rate in ankle release reduces the incidence of recurrent equinus deformity and the necessity for subsequent surgery in comparison to the results obtained with serial plaster casts or with tendo Achillis lengthening alone. Recent trends in clubfoot management have favored increasingly early operative intervention. Denham stated that "In the infant hard tissues (bone and cartilage) should be regarded as soft, and the soft tissues (tendon and ligament) as hard." Our operative experience with posterior ankle release supports this philosophy and indicates that early aggressive surgical management is the treatment of choice for the resistant clubfoot.

ABSTRACT

Of 294 patients with cerebral palsy seen from 1960 to 1972, forty-two had clinically significant lumbar and thoracolumbar scoliosis (31 to 135 degrees) and thirty-three were treated by spine surgery: ten by Harrington instrumentation and posterior spine fusion, eighteen by the Dwyer procedure and anterior fusion, and five by a two-stage combined anterior and posterior fusion. Evaluation of the results after eighteen to sixty-eight months showed: relief of pain in seventeen cases, improved sitting tolerance in seventeen, less nursing care needed in three, less equipment required in six, ability to use equipment providing more function in three, placement in a facility where less care was required in two, and improved eating patterns in two. Only the combined procedure appeared to give adequate correction and a low incidence of pseudarthrosis.

ABSTRACT

The spinal injured child has speical needs owing to the processes of physical, mental and social growth. Goals of physical treatment programs include prevention of: genitourinary complications; contractures; pressure sores; long bone fractures, hip subluxation and dislocation; spinal deformity. Nonoperative treatment of spinal deformity employing external support should be initiated when the potential for spinal deformity exists. External support delays the development of spinal deformity, improves sitting balance and allows free upper extremity use. The overall treatment programs must consider altered body proportions, immaturity of strength and coordination. Case examples of children with spinal injury are presented above to illustrate specific problems stemming from immaturity of physical, cognitive, and social development. Spinal surgery can be a conservative measure in the growing child when there is radiologic evidence of progressive spinal deformity. Posterior spinal fusion with Harrington instrumentation and external support permits immediate return to vertical activity.

ABSTRACT

Between 1954 and 1970, 351 patients with severe paralytic scoliosis were treated at Rancho Los Amigos Hospital. During this time the treatment evolved through five stages: body cast alone, halo cast, halo cast with buttons and traction wires, Harrington instrumentation, and finally preoperative halo-femoral traction and Harrington instrumentation. Coincident with this evolution, correction improved from 20 to 57 per cent, the incidence of curve progression dropped from 38 to 0 per cent, and curve extension decreased from 25 to 0 per cent, while postoperative recumbency was reduced from one year to about three weeks. In addition, complications changed, in general decreasing except for the rate of pseudarthrosis, which remained essentially the same. Clinically significant hyperlordosis involving the thoracic and lumbar spine was seen in sixteen patients who had long fusions from the fourth cervical vertebra and above to the fourth lumbar vertebra or the sacrum.
