Descemet Membrane Endothelial Keratoplasty for Late Corneal Edema Secondary to Obstetrical Forceps–Related Tears

Purpose: The purpose of our paper is to describe the outcome of Descemet membrane endothelial keratoplasty (DMEK) in patients with a history of known obstetrical forceps–related tears who developed clinically significant corneal edema in their eighth decade of life. Methods: Case series. Results: Two patients with a known history of obstetrical forceps–related tears presented with corneal edema and vertical tears of Descemet membrane consistent with birth trauma. DMEK was performed for both cases. Case 1 underwent pseudophakic DMEK, and Case 2 underwent combined phacoemulsification and DMEK (triple-DMEK). DMEK grafts were fully attached in both cases at postoperative 1-day and 1-week appointments, as confirmed on slit-lamp examination and anterior segment optical coherence tomography. There was marked improvement in best-corrected visual acuity and corneal edema in both patients. Conclusions: We demonstrate that DMEK can afford excellent results in patients with a history of obstetrical forceps injury, who experience corneal edema later in life. In addition, we show that the triple-DMEK can be done successfully in this entity.

High School Curriculum and Cognitive Function in the Eighth Decade of Life.

Formal educational attainment, or years of schooling, has a well-established positive effect on cognitive health across the life course. We hypothesized that the content and difficulty of the curriculum influence this relationship, such that more challenging curricula in high school lead to higher levels of socioeconomic attainment in adulthood and, in turn, to better cognitive outcomes in older adulthood. We estimated multilevel structural equation models (MSEMs) in data from 2,405 individuals who attended one of 1,312 US high schools in 1960 and participated in the Project Talent Aging Study in 2018. A college preparatory curriculum and a greater number of semesters of math and science in high school were positively related to word recall and verbal fluency at an average age of 75. Effects were robust to controlling for adolescent cognitive ability, academic performance, socioeconomic background, and school characteristics. We discuss the implications of these findings for educational policy.

Esophageal tuberculosis as a differential diagnosis of esophageal cancer.

The case of a patient in the eighth decade of life who begins with dysphagia and progressive weight loss is presented, who underwent contrast-enhanced tomography where a tumor was observed in the esophagus, endoscopy with biopsy and a report of esophageal tuberculosis.

A148 OSTEOSARCOMA GASTROINTESTINAL METASTASIS: A RARE ENTITY IN ADULTS

Abstract Background Osteosarcoma is highly aggressive and is the most common primary bone malignancy for both children and adults with a bimodal age distribution. The first peak coincides with pubertal growth spurt and the second is in the seventh and eighth decade of life. They frequently metastasize to the lungs. Metastasis to the gastrointestinal tract is extremely rare and to our knowledge, there have only been 15 cases reported in the literature since 1987, of those only three in the second peak. Aims Describe a case of 61-year-old female with periampullary metastatic osteosarcoma. Describe the demographics of osteosarcoma patients who develop gastrointestinal metastasis. Methods Search Pubmed using the terms: ("Osteosarcoma"[MeSH Terms] OR "Osteosarcoma"[Title/Abstract]) AND ("Gastrointestinal Tract"[MeSH Terms] OR "Gastrointestinal Tract"[Title/Abstract] AND "Case Reports"[Publication Type]. 113 articles were identified and screened by title. 15 articles were further screened by abstract or full text. 7 articles were identified. the remainder 7 articles were located by screening the references of the previously identified articles. Results A 61-year-old woman with a medical history significant for metastatic Osteosarcoma was referred to Gastroenterology clinic July 2023 for anemia investigation. Her Osteosarcoma was first diagnosed in the left femur in 2009. She was known for extensive bilateral lung metastasis, subcutaneous metastatic deposits, and distant bone metastasis. She had undergone over 37 surgeries and multiple sessions of radiotherapy. Aside from neoadjuvant and adjuvant chemotherapy for the primary tumor and the first occurrence of lung metastasis, she refused to undergo further cycles of chemotherapy. She had a 60 mg/dl hemoglobin drop from a previous one in December 2023 and intermittent melena. On gastroscopy, she was found to have a 2 cm bleeding mass in the periampullary area. The pathology report of the biopsies was consistent with metastatic osteosarcoma. It showed fragments of ampullary mucosa incorporating a malignant spindle cell neoplasm with a fascicular growth pattern, including scattered osteoclast-like giant cells, morphologically consistent with the known history of metastatic osteosarcoma. Of the 15 cases published, 9 were in patients 27 years old and younger, 3 were in patients 50 and older, and 3 were only available as titles. 50% of cases presented with intussusception while the rest had anemia or melena. The site of metastasis was the jejunum in the majority of patients (58%). Other sites included the ileum, stomach, colon, and esophagus. Only one other patient had periampullary metastasis. All patients had lung metastasis. Conclusions Gastrointestinal metastasis of osteosarcoma remains a rare occurrence. Our case report describes the second case reported in the literature of periampullary metastasis and the first case reported in older patients Funding Agencies None

Gallbladder volvulus by laparoscopic surgery

Gallbladder volvulus has a higher incidence between the sixth and eighth decades of life, exceptional condition for its infrequence. Since it tends to be confused with other pathologies, its diagnosis is usually intraoperative and can cause serious complications, such as gangrene, biliary sepsis and even death. We present the case of a 97-year-old patient who went to the emergency department with abdominal pain in the epigastric region, oppressive, irradiated to the right hypochondrium. Due to laboratory and imaging findings, a laparoscopic cholecystectomy was decided. During the surgery, a gallbladder volvulus was observed. The patient presented a satisfactory postoperative evolution, being discharged after 48 hours. This article presents a clinical case of vesicular volvulus and its proper laparoscopic management.

Cerebrovascular CO2 reactivity and dynamic cerebral autoregulation through the eighth decade of life and their implications for cognitive decline

Aging is accompanied by a decrease in cerebral blood flow (CBF), especially in the presence of preclinical cognitive decline. The role of cerebrovascular physiology including regulatory mechanisms of CBF in processes underlying aging and subclinical cognitive decline is, however, not fully understood. We explored changes in cerebrovascular CO2 reactivity and dynamic cerebral autoregulation (dCA) through the eighth decade of life, and their relation with early cognitive decline. After 10.9 years, twenty-eight (age, 80.0 ± 3.5 years; 46% female) out of forty-eight healthy older adults who had participated in a previous study (age at baseline, 70 ± 4 years; 42% female), underwent repeated transcranial Doppler assessments. Linear mixed-model analyses revealed small reductions in cerebrovascular CO2 reactivity with aging (−0.37%/mmHg, P = 0.041), whereas dCA was modestly enhanced (gain: −0.009 cm/s/mmHg, P = 0.038; phase: +8.9 degrees, P = 0.004). These changes were more pronounced in participants who had developed subjective memory complaints at follow-up. Our observations confirm that dCA is not impaired in aging, despite lower cerebral perfusion and cerebrovascular reactivity. Altogether, this unique longitudinal study highlights the involvement of cerebrovascular health in preclinical cognitive decline, which is of clinical relevance in the development of dementia management strategies.

The role of immune aging in Giant Cell Arteritis

Giant cell arteritis (GCA) is a granulomatous vasculitis with a predilection for medium and large calibre arteries. The most significant risk factor for its development is advancing age, with a peak incidence in the seventh and eighth decades of life. Despite this, until recently, the role of aging in disease pathogenesis has been largely overlooked. Advancing age is associated with numerous alterations in both the innate and adaptive immune system. Indeed, there is significant overlap in the cellular and molecular pathways involved in immune aging and those observed in the pathogenesis of GCA. In this review we explore these similarities and further expand the discussion on the postulated role of accelerated immune ageing in the pathogenesis of GCA. With the dramatic increase in lifespan in recent decades, elucidating the potential role of early immune aging in disease pathogenesis is extremely pertinent, with the potential to offer a new therapeutic avenue not only for those with GCA, but all immune mediated rheumatic diseases.

Morbidity of elective surgery for localized renal masses among elderly patients: A contemporary multicenter study

BackgroundThe aging population and the incidence of renal cell carcinoma (RCC) are increasing worldwide. Over 25% of newly diagnosed LRM (localized renal masses) occur in patients over the eighth decade of life. The decision-making and treatment approach to LRM in this population represents a clinical dilemma due to inherited decreased functional reserve and competing mortality risks. Current literature reports conflicting evidence regarding age as a risk factor for worst surgical outcomes. As such, we aimed to evaluate the contemporary morbidity of elective surgery for LRM among elderly patients, focusing on intraoperative and postoperative complications. MethodsAfter Ethical Committee approval, we queried our prospectively maintained databases to identify patients with preoperative eGFR ≥60 ml/min/1.73 m [(David and Bloom, 2022) 22 and a normal contralateral kidney who underwent partial or radical nephrectomy (PN or RN) for a single cT1-T2N0M0 LRM between 1/2015–12/2021 at four high-volume European Academic Institutions. Patients were categorized by age groups: <50 yrs (young) vs. 50–75 (middle-aged) yrs vs.> 75 yrs (elderly). Postoperative complications were recorded according to Clavien-Dindo (CD) classification. The primary objectives were the proportion of patients experiencing intraoperative (IOC), any grade (AGC), and high-grade postoperative complications (HGC), defined as CD grade 3–5. ResultsOverall, 2469/3076 (80.2%) patients met the inclusion criteria. Of these, 363 (14.7%) were young, 1682 (68.1%) were middle-aged, and 424 (17.2%) were elderly. Compared to middle-aged and young patients, elderly patients had a higher median Charlson Comorbidity Index (6 vs. 4 vs. 0, p < 0.01) and a higher proportion of cT1 renal mass (87.6% vs. 93.0% vs. 93.6%, p < 0.01). No differences among the study groups were found regarding surgical approach (open vs. minimally-invasive) and type of surgery (PN vs. RN). We found that older patients experienced similar IOC (4.5% vs. 4.2% vs. 3.3%, p = 0.7) and AGC (23.1% vs. 20.0% vs. 21.5%, p = 0.4) compared to middle-aged and young patients, respectively. Similarly, there were no significant differences in HGC between the study cohorts (0.7% vs. 1.4% vs. 1.7%, p = 0.8). At multivariable analysis, open approach and PN significantly predicted the occurrence of AGCs, while only the open surgical approach was associated with the occurrence of HGCs. ConclusionIn kidney cancer tertiary referral centers, the risk of IOC and postoperative HGC after PN or RN for localized renal masses (LRM) is low, despite a non-negligible risk of AGC, especially in elderly patients. Further efforts should focus on identifying multidisciplinary strategies to select patients most likely to benefit from surgery among elderly candidates with LRMs and decrease the morbidity of surgery in this specific setting.

Association of Performance on Olfactory and Cognitive Screening Tests With Conversion to Dementia in a Biracial Cohort of Older Adults.

Odor identification deficits are associated with transition to dementia, whereas intact odor identification and global cognition test performance may identify lack of transition. The purpose of this study was to examine intact odor identification and global cognition as prognostic indicators of lack of transition to dementia in a biracial (Black and White) cohort. In a community-dwelling sample of older adults from the Health, Aging, and Body Composition study, odor identification was measured using the Brief Smell Identification Test (BSIT), and global cognition was measured using the Teng Modified Mini-Mental State Examination (3MS). Survival analyses for dementia transition over 4 and 8 years of follow-up used Cox proportional hazards models. A total of 2,240 participants had an average age of 75.5 years (SD 2.8). Approximately 52.7% were female individuals. Approximately 36.7% were Black and 63.3% were White individuals. Impaired odor identification (hazard ratio [HR] 2.29, 95% CI 1.79-2.94, p < 0.001) and global cognition (HR 3.31, 95% CI 2.26-4.84, p < 0.001) were each independently associated with transition to dementia (n = 281). Odor identification remained robustly associated with transition to dementia for Black (HR 2.02, 95% CI 1.36-3.00, p < 0.001, n = 821) and White participants (HR 2.45, 95% CI 1.77-3.38, p < 0.001, n = 1,419), whereas global cognition was associated with transition among Black participants only (HR 5.06, 95% CI 3.18-8.07, p < 0.001). ApoE genotype was consistently associated with transition among White participants only (HR 1.75, 95% CI 1.20-2.54, p < 0.01). Among participants with intact performance on both odor identification (BSIT ≥9/12 correct) and global cognition (3MS ≥ 78/100 correct), 8.8% transitioned to dementia over 8 years. Intact performance on both measures had high positive predictive value for identifying individuals who did not transition to dementia over 4 years (0.98 for ages 70-75 years with only 2.3% transitioning, 0.94 for ages 76-82 years with only 5.8% transitioning). Odor identification testing paired with a global cognitive screening test identified individuals at low risk of transition to dementia in a biracial community cohort with a pronounced effect in the eighth decade of life. Identification of such individuals can reduce the need for extensive investigation to establish a diagnosis. Odor identification deficits showed utility in both Black and White participants, unlike the race-dependent utility of a global cognitive test and ApoE genotype.

Broadening the Understanding of Mucinous Carcinoma of the Breast

Mucinous carcinoma (MC) is a rare invasive neoplasm comprising only 2% to 4% of all breast cancers,1 commonly affecting women under the sixth through eighth decades of life. Also referred to as colloid carcinoma, MC has been historically described as a circumscribed, round mass with indolent behavior occurring in older women. This is an oversimplification. The imaging appearance, biological behavior, and demographic profile of MC are variable, often correlating with histologic subtype and nuclear differentiation and in some instances mimicking benign pathologies. Broadening the understanding of MC will help radiologists establish concordance, guide clinical management, and accurately surveille cases in multidisciplinary tumor boards.

Hospitalization Burden of Patients with Kidney Stones and Metabolic Comorbidities in Spain during the Period 2017-2020.

Nephrolithiasis has become an increasing worldwide problem during the last decades. Metabolic syndrome, its components, and related dietary factors have been pointed out as responsible for the increasing incidence. The objective of this study was to evaluate the trends in the hospitalization rates of patients with nephrolithiasis, hospitalization features, costs, and how metabolic syndrome traits influence both the prevalence and complications of lithiasic patients. An observational retrospective study was conducted by analyzing hospitalization records from the minimum basic data set, including all patient hospitalizations in Spain in which nephrolithiasis has been coded as a main diagnosis or as a comorbidity during the period 2017-2020. A total of 106,407 patients were hospitalized and coded for kidney or ureteral lithiasis in this period. The mean age of the patients was 58.28 years (CI95%: 58.18-58.38); 56.8% were male, and the median length of stay was 5.23 days (CI95%: 5.06-5.39). In 56,884 (53.5%) patients, kidney or ureteral lithiasis were coded as the main diagnosis; the rest of the patients were coded mostly as direct complications of kidney or ureteral stones, such as "non-pecified renal colic", "acute pyelonephritis", or "tract urinary infection". The hospitalization rate was 56.7 (CI95%: 56.3-57.01) patients per 100,000 inhabitants, showing neither a significant increasing nor decreasing trend, although it was influenced by the COVID-19 pandemic. The mortality rate was 1.6% (CI95%: 1.5-1.7), which was higher, if lithiasis was coded as a comorbidity (3.4% CI95%: 3.2-3.6). Metabolic syndrome diagnosis component codes increased the association with kidney lithiasis when age was higher, reaching the highest in the eighth decade of life. Age, diabetes, and hypertension or lithiasis coded as a comorbidity were the most common causes associated with the mortality of lithiasic patients. In Spain, the hospitalization rate of kidney lithiasis has remained stable during the period of study. The mortality rate in lithiasic patients is higher in elderly patients, being associated with urinary tract infections. Comorbidity conditions such as diabetes mellitus and hypertension are mortality predictors.

Substance Use in U.S. Vietnam War Era Veterans and Nonveterans: Results from the Vietnam Era Health Retrospective Observational Study

Background: Substance use (SU) is associated with physical injury and mental health disorders in older persons, but recent research has scarcely examined SU in U.S. Vietnam-era veterans who are mostly in or near their eighth decade of life. Objectives: We compared the prevalence of self-reported lifetime and current SU and modeled current usage patterns in a nationally representative sample of veterans versus a matched nonveteran cohort. Methods: Cross-sectional, self-reported survey data were analyzed from the 2016–2017 Vietnam Era Health Retrospective Observational Study (VE-HEROeS) (n = 18,866 veterans, n = 4,530 nonveterans). We assessed lifetime and current alcohol and drug use disorders; lifetime and current use of cannabis, opioids, stimulants, sedatives, “other drugs” (psychedelics, prescription or over-the-counter drugs not prescribed/used as intended); and current SU patterns (alcohol-use-only, drug-use-only, dual-SU, no SU). Weighted descriptive, bivariable, and multivariable statistics were calculated. Covariates in multinomial modeling included sociodemographic characteristics, lifetime cigarette smoking, depression, potentially traumatic events (PTEs), and current pain (SF-8TM). Results: Prevalence of lifetime opioid and sedative use (p ≤ .01), drug and alcohol use disorders (p < .001), and current “other drug” use (p < .001) were higher in veterans versus nonveterans. Current use of alcohol and cannabis was high in both cohorts. In veterans, very severe/severe pain, depression, and PTEs were highly associated with drug-use-only (p < .001) and dual-SU (p < .01), but these associations were fewer for nonveterans. Conclusion: This research confirmed existing concerns over substance misuse in older individuals. Vietnam-era veterans may be at particular risk due to service-related experiences and later-life tribulations. Era veterans’ unique perceptions toward healthcare assistance for SU may need greater provider focus to maximize self-efficacy and treatment.

3D bioprinting-a model for skin aging.

Human lifespan continues to extend as an unprecedented number of people reach their seventh and eighth decades of life, unveiling chronic conditions that affect the older adult. Age-related skin conditions include senile purpura, seborrheic keratoses, pemphigus vulgaris, bullous pemphigoid, diabetic foot wounds and skin cancer. Current methods of drug testing prior to clinical trials require the use of pre-clinical animal models, which are often unable to adequately replicate human skin response. Therefore, a reliable model for aged human skin is needed. The current challenges in developing an aged human skin model include the intrinsic variability in skin architecture from person to person. An ideal skin model would incorporate innate functionality such as sensation, vascularization and regeneration. The advent of 3D bioprinting allows us to create human skin equivalent for use as clinical-grade surgical graft, for drug testing and other needs. In this review, we describe the process of human skin aging and outline the steps to create an aged skin model with 3D bioprinting using skin cells (i.e. keratinocytes, fibroblasts and melanocytes). We also provide an overview of current bioprinted skin models, associated limitations and direction for future research.

Polymorphous low-grade adenocarcinoma: a report of two cases

&lt;p class="abstract"&gt;Polymorphous low-grade adenocarcinoma (PLGA) is an infrequent type of malignant epithelial tumor that occurs almost exclusively in minor salivary glands. It commonly presents in women between the sixth and eighth decade of life, usually as an asymptomatic mass of long evolution and slow growth in the oral cavity but can erode and infiltrate adjacent bone. We present 2 case reports and review the literature on the subject. One case presented with a growing mass that developed over the course of 12 years, incorrectly diagnosed in the first incisional biopsy as a benign tumor. The second case presented as a recurring PLGA 19 years after the first, which appeared at an unusually young age. Both cases were managed with the treatment of choice: surgery with wide excision margins. Although prophylactic neck dissection is not the rule, it was part of the postoperative treatment in both cases, along with life-long follow-ups to find recurrences at early stages. A high level of suspicion and knowledge regarding its presentation are essential for correct diagnosis and management.&lt;/p&gt;

Sternotomy in thyroid surgery

Introduction: A bulky retrosternal goiter means for the surgeon to consider an extracervical approach, usually from a partial sternotomy. Methods: Retrospective evaluation of a group of thyroid operations requiring sternotomy in a ten-year period (year 2012–2021), in an attempt to predict the need for sternotomy. Results: We performed a total of 1254 thyroid operations, with partial sternotomy required in 11 cases (0.88%): in 6 women and 5 men aged 43–84 years (mean 73.1 years). For these, 3 total thyroidectomies and 6 hemithyroidectomies (lobectomies) were performed. In 2 cases, we operated on the mediastinal residue, or regenerate, after a previous thyroidectomy from the cervical approach. The duration of hospitalization was 5–14 days, once there was bleeding with the need for operative revision, otherwise the procedures were without complications, including phonation. The border of the lower part of the thyroid gland in relation to the upper border of the aortic arch was in the range of +20 to -22 mm. The mean was -8.5 mm. Conclusion: All sternotomy thyroidectomies performed by us had a close relationship to, or overlapped with the upper line of the aortic arch. Significantly retrosternal propagating goiters are mostly eufunctional (81.9 % in our group) and develop in patients in the seventh or eighth decade of life. Therefore, if only one lobe propagates intrathoracically, a hemithyroidectomy is sufficient. A carcinoma is rarely present; in one case in our group. We believe that the necessity of sternotomy cannot be accurately predicted, but it is necessary to be prepared for it, especially in the case of a goiter exceeding the level of the aortic arch. In case of greater retrosternal propagation, it is certainly appropriate to perform a CT, for surgical reasons (possibility of sternotomy, risk of leaving part of the gland) and anesthetic reasons (compression and deviation of the trachea).

An unusual case of sequential corneal perforation in pellucid marginal degeneration

Spontaneous and sequential corneal perforation is rare in pellucid marginal degeneration (PMD) in the seventh decade of life. Hence, the importance of repeated follow-up, clinical examination along with serial corneal topography even in the seventh and eighth decades of life is of utmost importance in PMD. We report a case of spontaneous corneal perforation in a 64-year-old male patient with PMD having normal corneal thickness in the right eye which was managed with primary suturing and compression sutures. The other eye was absolutely normal with normal topographic findings. Over a period of four years of follow-up, the patient developed progressive diminution of vision in both eyes and was diagnosed with cataract. Temporal phacoemulsification with toric IOL implantation was done in both eyes, following which the left eye developed spontaneous perforation after a period of two months which was also managed with primary suturing and compression sutures.

High rate of missed Barrett’s esophagus when screening with forceps biopsies

BackgroundScreening for Barrett’s esophagus (BE) with endoscopy plus forceps biopsy (FB) has poor compliance with the recommended Seattle protocol and fails to sample large areas of mucosa. This statistical modeling study estimates, for the first time, the actual frequency of missed BE cases by FB.MethodsPublished, calibrated models in the literature were combined to calculate the age-specific prevalence of BE in white males with gastroesophageal reflux disease (GERD). We started with estimates of the prevalence of BE and GERD, and applied the relative risk for BE in patients with GERD based on the literature. This created estimates of the true prevalence of BE in white males with GERD by decade of life. The proportion of BE missed was calculated as the difference between the prevalence and the proportion with a positive screen.ResultsThe prevalence of BE in white males with GERD was 8.9%, 12.1%, 15.3%, 18.7% and 22.0% for the third through eighth decades of life. Even after assuming no false positives, missed cases of BE were about 50% when estimated for patients of ages 50 or 60 years, and over 60% for ages of 30, 40 or 70 years. Sensitivity analysis was done for all variables in the model calculations. For ages 50 and 60 years, this resulted in values from 30.3 to 57.3% and 36.4 to 60.9%.ConclusionScreening for BE with endoscopy and FB misses approximately 50% of BE cases. More sensitive methods of BE detection or better adherence to the Seattle protocol are needed.

The Eyelid Angiosarcoma: A Systematic Review of Characteristics and Clinical Course.

A systematic search for eyelid angiosarcoma was performed from inception to December 2020 in Medline, EMBASE, and the Cochrane databases. Forty two eyelid angiosarcoma cases in 32 articles were analyzed. Eyelid angiosarcomas showed an incidence peak in the eighth decade of life, and was reported more frequently in Caucasian males. Eyelid angiosarcomas were associated with a mortality rate of 26.2%, a recurrence rate of 14.3%, and a cure rate of 45.2%. Four years event-free survival (EFS) rate was 36.0%, with median EFS of 36 months. Eyelid angiosarcomas with bilateral involvement or metastasis showed higher mortality and recurrence rates than unilateral eyelid invasion cases. In the prognosis analysis according to treatment modalities, the mortality and recurrence rates were the lowest in patients who underwent surgical excision. The 4-year EFS probability in a group with surgical excision was 60.6%, but in a group without surgical excision it was 30.3%. A total of 45.2% of the cases was misdiagnosed and 21.4% of the cases could not be correctly diagnosed with the first biopsy trial. The prognosis for eyelid angiosarcomas was better than that of angiosarcomas invading the face and scalp. Surgical excision was the most important treatment modality; thus, should be considered as the first treatment of choice.

Breast cancer risk factors depended on a statistical study in Sabratha Oncology hospital from 2006 to 2016

Breast cancer is the primary cause of death in women in developed countries. The main objective of this study is to define the relationship between breast cancer, gender, and age, based on a statistical study in Sabratha Oncology Institute during the years of 2006 to 2016. The study included 2429 patients registered for eleven years (2006-2016). Two thousand three hundred sixty-four (3164) cases were females (97.33%) and 65 males (2.67%). The average ages were 45.48 years for females and 54.93 years for males. The study showed a clear relationship between breast cancer and gender; as for age, there was varies between men and women. The study also revealed that the incidence of breast cancer increases with age and occurs mainly during the third and fourth decades of life for women. At the same time, it is of minor occurrence during the following decades of a woman's life. As for men, breast cancer is of more common occurrence between the fifth and eighth decades of life.

Medical history, medication use and physical activity in adults in their eighth and ninth decade of life in the Hertfordshire Cohort Study.

While there are many known health benefits to maintained physical activity levels in late adulthood, there have been very few studies that have considered relationships between morbidity profile and physical activity in the eighth decade of life. We studied 1097 participants, 555 men and 542 women from the Hertfordshire Cohort Study, a UK community based sample. Validated questionnaire based data were used to relate self-reported physical activity (PA) levels to medical history, and medication use. Regression analyses were adjusted for age, BMI, smoker status, alcohol consumption. The mean (SD) age of participants in the study was 80.2 (2.7) years for men and 80.2 (2.6) for women. A higher proportion of men (33.7 %) than women (24 %) were in the high activity score group. 20.8 % of female participants and 22.6 % male participants reported having no comorbid disease; 10.5 % men and 8.4 % women were taking no medication. Higher number of chronic conditions was associated with lower levels of PA [men (OR 0.73, 95 % CI 0.63-0.84, p<0.001); women (OR 0.74, 95 % CI 0.64-0.86, p<0.001)] as was being prescribed a higher number of medications [men (OR 0.88, 95 % CI 0.84-0.93, p<0.001); women (OR 0.86, 95 % CI 0.82-0.91, p<0.001)]. All these associations remained robust following adjustments. Strong relationships were seen in both sexes between PA and taking medication for disorders of the central nervous system and gastrointestinal system, with relationships generally stronger in men. We have observed relationships between comorbid medical history and medication use with physical activity in a cohort of community dwelling older adults. These highlight the need to consider medical history when considering how best to optimize PA in older adults.
