RESUMEN

OBJECTIVES: We aimed to assess Long COVID sexual dysfunction among both sexes. PATIENTS AND METHODS: A cross-sectional study at a multidisciplinary COVID clinic. Consecutive patients answered a symptom-based questionnaire, which included sexual dysfunction. Individuals reporting any degree of sexual dysfunction were compared with those who denied. A multivariable logistic regression was conducted to identify risk factors. A principal component analysis was implemented to explore other symptoms associated with sexual dysfunction. RESULTS: All in all, 391 individuals recovering from COVID-19 completed the questionnaire, 211 women and 180 men. Mean age was 45.2 (SD 15.4) years. Most (280, 85.9%) had mild COVID-19, assessed at a median of 3.8 (IQR 2.0) months from diagnosis. Sexual dysfunction was reported by 55 (36%) of the men and 48 (28%) of the women. Increased age [per year; men OR 1.05 (95% CI 1.02-1.08)], long COVID cough [men 2.58 (1.05-6.32)], chest pain [women 3.54 (1.28-9.80)], irritability [women 3.45 (1.28-9.29)], paresthesia [men 4.23 (1.55-10.44); women 3.08 (1.14-8.32)], and emotional distress [men 3.26 (1.36-7.82); women 4.29 (1.65-11.18)] were significantly associated with sexual dysfunction. In women, sexual dysfunction was part of the emotional pattern, while among men, it was part of the emotional and pulmonary patterns. CONCLUSION: Sexual dysfunction is a common manifestation of long COVID in both men and women. Presence of other long COVID symptoms, and older age, are associated with this phenomenon. Further studies should explore the mechanisms for long COVID sexual dysfunction in both men and women, as well as strategies for prevention and treatment.

RESUMEN

Prior research on the interaction between emotion and episodic memory established that negatively charged events are better remembered compared to neutral events (i.e. enhanced remembrance), as well as that a priori neutral cues that were present in the environment during a negative event can attain aversive meaning by themselves (i.e. acquired negativity). Improved understanding the neural mechanisms that mediate enhanced remembrance of negative episodes and acquired negativity of related neutral cues may carry substantial clinical relevance, particularly in the context of posttraumatic pathophysiology. In order to address this point forty-nine healthy participants completed a novel fMRI task that involve the presentation of neutral pictures before and after a series of short neutral and aversive video-clips from which the neutral pictures were originally extracted, and a subsequent presentation of these pictures as cues for clip recall [termed, Picture-Clip-Picture-Recall (PCPR) task]. Behavioral results indicate that aversive clips were indeed better remembered compared to neutral clips (i.e. enhanced remembrance of negative episode) and that a priori neutral pictures that appeared in aversive clips were rated more negatively after relative to before the exposure to the aversive clips (i.e. acquired negativity of related neutral cues). Whole-brain fMRI analysis revealed that increased amygdala activation in response to pictures when presented as cues for clip recall predicted successful clip remembrance, particularly remembrance of aversive clips. This amygdala activation was also correlated with the magnitude of acquired negativity of the cues following their appearance in aversive clips. Taken together our findings implicate the PCPR as a novel, naturalistic, framework for investigating the neural interface of emotional episodic memory, while highlighting the role of the amygdala in enhanced remembrance of negative episodes and acquired negativity of related neutral cues. Clinical implications are discussed.

RESUMEN

BACKGROUND: Memory impairment is prevalent in systemic lupus erythematosus (SLE); however, its pathogenesis is unknown. In a previous functional magnetic resonance imaging (fMRI) study we demonstrated altered brain activity dynamics and less brain deactivation in patients with SLE as compared with healthy controls, when performing a learning and memory task. Our findings localized this impairment to the default mode network (DMN), and particularly to its anterior medial prefrontal cortex node. In addition, altered networking of the hippocampal subsystem of the DMN was seen in patients with SLE when performing this task, as well as atrophy of the left hippocampus. The present study aimed to search for a structural substrate for the altered recruitment pattern observed in fMRI studies using diffusion tensor imaging (DTI). PATIENTS AND METHODS: Using DTI, we characterized brain diffusivity in 10 patients with SLE and nine healthy controls. Two tracts associated with the DMN were reconstructed: the corpus callosum (CC) and the cingulum bundle. The CC was segmented according to the Witelson segmentation scheme and the cingulum was segmented into superior and descending bundles. RESULTS: A significant increase in mean diffusivity (MD) was seen in patients with SLE without neuropsychiatric SLE (NPSLE) as compared with healthy controls in all five segments of the CC (segment 1: p = 0.043; segment 2: p = 0.005; segment 3: p = 0.003; segment 4: p = 0.012; segment 5: p = 0.023) as well as in the descending portion of the left cingulum bundle (p = 0.026). CONCLUSIONS: Increased MD values in the CC and the left cingulum may indicate impaired organization/reduced integrity of these tracts, which may underlie the abnormal pattern of brain activity recruitment of the DMN observed during a verbal learning and memory task. Taking into account the central role of the left hippocampus in verbal memory, the abnormal integrity of the left cingulum may contribute to the reduced performance of patients with SLE on verbal memory tasks.

RESUMEN

OBJECTIVE: The purpose of this study was to assess and characterise verbal memory impairment in patients with systemic lupus erythematosus (SLE) by the Rey Auditory Verbal Learning Test (Rey AVLT). METHODS: 40 consecutive, unselected patients with SLE were evaluated with the Rey AVLT, a clinical and research tool for the study of multiple learning and memory measures. All patients were assessed for disease activity, damage, presence of antiphospholipid antibodies and depression. Findings were compared with those of 40 healthy controls matched for age, sex and education. RESULTS: The study group included 40 patients with SLE (37 females, 3 males), median age 33 years (range 20-59), median disease duration 8 years (range 0.3-32). The median disease activity measured by the SLE Disease Activity Index (SLEDAI) was 4 (range 0-16). Median damage measured by the SLICC/ACR (Systemic Lupus International Collaborating Clinics/American College of Rheumatology) damage index score was 0 (range 0-4). Depression was detected in 16/40 patients. Several aspects of the memory domain, as measured by the Rey AVLT, were impaired in the SLE group, using analysis of variance with repeated measures. The learning curve of patients with SLE was significantly less steep compared with that of controls, (p = 0.036), the rate of words omitted from trial to trial was higher in the SLE group (p = 0.034) and retrieval was less efficient in SLE compared with controls (p = 0.004). The significance of these findings was maintained after omitting patients with stroke or depression. CONCLUSION: Learning ability was impaired in patients with SLE with a poor and inefficient learning strategy, as reflected by an impaired learning curve, repeated omissions and impaired retrieval. This pattern of memory deficit resembles that seen in patients with frontal lobe damage and warrants further localising brain studies.

RESUMEN

Nausea and vomiting in advanced cancer, occurring as a manifestation of the disease process or as a complication of drugs used for symptom control, can be controlled rapidly in most instances using the protocol described. This involves an informed appraisal of the cause or causes of nausea and vomiting, combined with application of knowledge of the mechanisms of emesis and the action of antiemetics. Different mechanisms appear to responsible for emesis after chemotherapy and irradiation and for anticipatory vomiting. Ondansetron combined with dexamethasone appears to be the most effective regimen for post-cisplatin emesis. For less emetogenic agents, dexamethasone alone, or in combination with ondansetron for refractory cases, gives good control. For the control of vomiting induced by single-fraction radiotherapy to the upper abdomen, ondansetron is very effective. Management of anticipatory vomiting should concentrate on prevention, but once vomiting is established, behavioral therapy and the amnesic properties of lorazepam may be used.

RESUMEN

AIMS: Because of widely differing views on the drugs that can be administered in combination, this study was undertaken to record the combination of drugs in syringe drivers that we had found to be compatible. METHODS: The content of syringe drivers in 100 consecutive patients in whom continuous subcutaneous infusion was used, was recorded. The incidence of skin reactions with the different drugs was noted. The efficacy of combinations used was assessed clinically. RESULTS: A wide variety of drugs were used in many different combinations, with no clinical evidence of loss of efficacy. Some drug combinations are incompatible. Drugs known to cause skin reactions were not administered. In this study skin reactions depended on the number of drugs used in combination. CONCLUSIONS: The array of medications that can be used together in syringe drivers enable this method of drug administration to be used successfully in the control of the diverse symptoms that may arise in terminal illness. Further study is needed for quantitative measurement of drug stability.

RESUMEN

AIM: To reduce the time taken to achieve relief when a strong narcotic is indicated for the control of cancer pain. METHOD: A method of accelerated titration of morphine dosage is described. The time taken to achieve good pain control in 50 consecutive terminally ill cancer patients was recorded. RESULTS: The average time to taken to control pain was 26 hours for patients being cared for at home, and 6 hours for hospice inpatients. CONCLUSIONS: Rapid pain control with morphine can be achieved safely within hours in most cancer patients with morphine responsive pain.

RESUMEN

The feeling that life has had no meaning is an impediment to a peaceful death. Life review enables a person to identify events that have been of worth and so enhances self-esteem. This approach has been extended and formalized by establishing a biographer service to compile oral and written biographies of patients who may be expected to benefit from such a re-examination of their lives. The service is now also being offered to patients whose disability precludes most other forms of activity. The value of biography as therapy is considered and it is concluded that it has much to offer in the circumstances described.

RESUMEN

A wide variety of causes may be responsible for nausea and vomiting in terminal illness. The different emetic stimuli reach the vomiting centre by a variety of pathways and can be blocked by specific antiemetics that act at the neurotransmitter receptor sites in these pathways. A knowledge of the neurotransmitter receptor antagonist potency of the different antiemetics allows the choice of the most appropriate antiemetic for the relief of the nausea and vomiting caused by a particular emetic stimulus. To demonstrate the efficacy of this approach to the management of nausea and vomiting in terminal illness, the outcome of antiemetic choice in 100 consecutive episodes is recorded.

RESUMEN

The choice of antiemetic should not be arbitrary, but should be based on knowledge of the different pathways of the various stimuli that lead to nausea and vomiting and the neuroreceptors involved. The steps to be taken in choosing an appropriate antiemetic are described. They are (a) to establish the probable cause of the nausea and vomiting, (b) to consider the afferent pathways involved, (c) to define the neuroreceptors activated at each of these sites, (d) to select the group of antiemetics that antagonizes these neuroreceptors, and (e) to choose the most potent antiemetic with the fewest side effects in that group. Causes for failure to respond to a chosen antiemetic are considered and the action to be taken is described.

RESUMEN

Though patients usually die peacefully, problems may arise in the last period of a terminal illness. In the final days new symptoms may arise or there may be exacerbation or recurrence of symptoms previously well controlled. Two hundred consecutive hospice patients were studied. The incidence was noted of pain, dyspnea, moist breathing, nausea and vomiting, confusion, restlessness, jerking and twitching, difficulty in swallowing, incontinence and retention of urine, sweating, moaning and groaning, and loss of consciousness. Each symptom is considered and the results of the management employed are noted. Many of the features appearing in the last days of a terminal illness, especially cancer, can be attributed to organic brain disease consequent to metabolic disorder associated with multi-organ failure. An awareness of the nature of the problems that may arise in the last 48 hours of life makes it possible to keep the patient comfortable to the end.

RESUMEN

A randomized single-blind study was designed to compare the performance on memory tests requiring recall of information relevant to everyday life of two groups of hypertensive patients. One group of 13 patients were taking a beta-adrenoceptor blocker (atenolol) and the other group of 12 patients received the angiotensin-converting enzyme inhibitor (enalapril). The results suggested that when compared with placebo the group of patients treated with enalapril showed no changes in memory function, whilst there was a mild, but consistent deficit in the group taking atenolol.

RESUMEN

Patients with a pharyngoesophageal pouch studied by esophageal manometry were shown to have premature relaxation of the upper esophageal sphincter. Postrelaxation contraction of the sphincter was therefore already in progress while pharyngeal contraction was taking place. This motor disturbance creates a physiological obstruction at the upper esophageal sphincter so that high pressures are built up in the pharynx. These conditions are conductive to herniation of the pharyngeal mucosa through any weak area in the muscle wall of the pharynx.

RESUMEN

Clinical features suggesting lung disease in three patients and a chance chest radiograph in the fourth led to films showing localized lung lesions with some characteristics of neoplasms. Two were heavy smokers, two were non-smokers. In two the lesion was peripheral, in one lobar (RUL), and in the fourth it crossed the interlobar fissure (apical and posterior segments LUL and apical LLL). Malignant cells were not seen on sputum cytology examination in any, but in one, atypical cells were reported. All four patients had lung resection for suspected cancer, two by pneumonectomy, one by lobectomy, and one lingulectomy. All patients recovered, and their clinical course has so far been uniformly benign. Two have been followed long term (16 and 10 years), one 2 1/2 years, and one a year. Pathologically, the lesions appeared to be strictly limited without extra-pulmonary involvement, except that the patient followed for one year has developed hyporegenerative anaemia responsive to prednisone therapy. The pathological features of focal necrosis, granulomatous inflammation, and vasculitis were sufficiently striking, although often focal, to suggest that incisional biopsy from frozen-section histological diagnosis could be useful to prevent extensive lung resection for lesions not positively diagnosed before thoracotomy.

RESUMEN

The pattern of swallowing during sleep was investigated by means of a study in 10 normal subjects. Sleep was staged by means of EEG, EOG and EMG, and swallowing was monitored by means of an external sensing device attached to the neck. It was found that during sleep, swallowing is episodic, with long swallow-free periods. Swallows occur almost exculusively in association with movement arousals which are most frequent during Stages REM, 1 and 2 of sleep.

RESUMEN

Experience with 40 patients and 150 pacemakersss is reviewed. In 13 patients the initial pacing was by epicardial electrodes and in 27 by transvenous catheter electrodes. When epicardial systems were used, two electrodes were always fixed to the heart, the additional electrode being provided for temporary pacing and as a spare in case of future need. The battery unit was usually buried behind the rectus abdominis muscle. Vacuum drainage of the pacemaker pocket was used and was considered helpful in avoiding some complications. The right cephalic vein was preferred for transvenous pacing but existing venous abnormalities sometimes required use of the external jugular vein. Five patients had epicardial systems changed to transvenous ones, and in 5 the reverse procedure was needed. Pacemaker battery problems included inadequate soft tissue protection for the unit, epoxy resion fracture, titanium case leak and problems relating to design change and the special needs for overseas travel. While the danger from diathermy and radiofrequency is now recognized, similar dangers exist for those paced by 'demand' units in large electromagnetic fields.

RESUMEN

Serial plasma cortisol estimations were carried out in 81 male lung cancer patients and in a control group of 50 male subjects with conditions other than lung cancer. It was found that group mean plasma cortisol levels, both in the morning and in the afternoon, were greater in the lung cancer patients than in the no-cancer control group. However, long-term assessment four years after the beginning of the study showed that high plasma cortisol levels were found predominantly in cancer patients within six months of death. If such patients are excluded from the study, there is no significant difference in group mean plasma cortisol levels between male lung cancer patients and a male control group.
