Information and oncosexological management in breast cancer patients

OBJECTIVES

Breast cancer treatment is a particularly high-risk situation for the deterioration of sexual health, leading to an alteration in body image and physical deteriorations such as vaginal trophicity. The aim of this study was to evaluate the information received by patients concerning this alteration of their sexual health in relation to their treatment, and to identify their expectations and needs in terms of oncosexual management.

STUDY DESIGN

A bicentric qualitative retrospective study was conducted, involving women aged 18 to 80, treated for breast cancer by total or partial mastectomy after 2014 and having had a follow-up consultation between July and December 2019. Data were collected using medical files and a de-identified questionnaire sent by post or e-mail after obtaining consent. The main outcome measures were the proportion of patients who received informations about oncosexology and those who felt impact on their sexual health.

RESULTS

Of the 274 patients included in the study, 60% said they had received no information about the sexological side effects of their disease or treatment. Of these, 62.5% dared not talk about it during consultation. Patients were keen to receive oncosexological advice or treatment from a specialized nurse or doctor. In 76.1% of cases, patients declared that they had been sexually active in the year prior to their cancer diagnosis, compared with 54.94% after treatment. They reported a loss of femininity in 24% of cases, and 40.5% had no sexual desire.

CONCLUSION

Women treated for breast cancer report a lasting alteration in their body image and sexual activity. Information on the impact of the disease and its treatment on sexual health is inadequate, even though patients are keen to receive specialized care with professional sexology consultations. The impact of breast cancer on sexual health should systematically explained to the patients, especially as treatment options exist and can be offered.

Critically ill COVID-19 patients attended by anesthesiologists in northwestern Spain: a multicenter prospective observational study

BACKGROUND AND OBJECTIVES

There are limited information on outcome, complications and treatments of critically ill COVID-19 patients requiring admission to an intensive care unit (ICU). The aim of this study is to describe the clinical ICU course, treatments used, complications and outcomes, of critically ill COVID-19 patients admitted in seven ICU in Galicia region during the 2020 March-April pandemic peak.

METHODS

Between March 21 and April 19, 2020, we evaluated critically ill COVID-19 patients admitted to the ICU of Anesthesia of seven hospitals in Galicia, northwestern Spain. Outcome, complications, and treatments were monitored until May 6, 2020, the final date of follow-up.

RESULTS

A total of 97 critically ill COVID-19 patients were included. During ICU stay, mechanical ventilation became necessary in 80 (82.5%) patients, and tracheostomy in 22 (22.7%) patients. Prone position was used frequently in both intubated (67.5%) and awake (27.8%) patients. Medications consisted of antivirals agents (92.7%), corticosteroids (93.8%), tocilizumab (57.7%), and intermediate or high doses of anticoagulants (83.5%). The most frequent complications were ICU-acquired infection (52.6%), thrombosis events (16.5%), and reintubation (9.3%). After a median follow-up of 42 (34-45) days, 15 patients (15.5%) deceased, 73 patients (75.2%) had been discharged from ICU, and nine patients (9.3%) were still in the ICU.

CONCLUSIONS

A high proportion of our critically ill COVID-19 patients required mechanical ventilation, prone positioning, antiviral medication, corticosteroids, and anticoagulants. ICU complications were frequent, mainly infections and thrombotic events. We had a relatively low mortality of 15,5%.

Association between vitamin D deficiency and common variants of Vitamin D binding protein gene among Mexican Mestizo and indigenous postmenopausal women

PURPOSE

Vitamin D deficiency (VDD) and polymorphisms in the group-specific component (GC) gene are known to be associated in different populations. However, the effects of such genetic variants may vary across different populations. Thus, the objective of this study was to estimate the association between Vitamin D-Binding Protein (VDBP) haplotypes and VDD in mestizo postmenopausal women and Mexican Amerindian ethnic groups.

METHODS

This was a cross-sectional study of 726 postmenopausal Mexican women from the Health Workers Cohort Study (HWCS) and 166 postmenopausal women from the Metabolic Analysis in an Indigenous Sample (MAIS) cohort in Mexico. GC polymorphisms (rs7045 and rs4588) were analyzed by TaqMan probes. Serum 25-hydroxyvitamin D [25(OH)D] levels were measured by Chemiluminescent Microparticle Immuno Assay.

RESULTS

The prevalence of VDD serum 25(OH)D < 20 ng/mL was 43.7% in mestizo women and 44.6% in indigenous women. In HWCS, the single nucleotide polymorphisms (SNPs) rs7041 and rs4588 were associated with VDD. In addition, women from the HWCS, carrying the haplotypes GC2/2 and GC1f/2 had higher odds of VDD (OR = 2.83, 95% CI 1.14, 7.02; and OR = 2.30, 95% CI 1.40, 3.78, respectively) compared to women with haplotype 1f/1 s. These associations were not statistically significant in the MAIS cohort.

CONCLUSIONS

Our results show genetic association of the analyzed SNPs and related haplotypes, on the GC gene, with VDD in mestizo Mexican postmenopausal women. Moreover, a high prevalence of VDD with high genetic variability within the country was observed. Our results support the need for national policies for preventing VDD.

Automatic speech analysis to early detect functional cognitive decline in elderly population

This study aimed at evaluating whether people with a normal cognitive function can be discriminated from subjects with a mild impairment of cognitive function based on a set of acoustic features derived from spontaneous speech. Voice recordings from 90 Italian subjects (age >65 years; group 1: 47 subjects with MMSE>26; group 2: 43 subjects with 20≤ MMSE ≤26) were collected. Voice samples were processed using a MATLAB-based custom software to derive a broad set of known acoustic features. Linear mixed model analyses were performed to select the features able to significantly distinguish between groups. The selected features (% of unvoiced segments, duration of unvoiced segments, % of voice breaks, speech rate, and duration of syllables), alone or in addition to age and years of education, were used to build a learning-based classifier. The leave-one-out cross validation was used for testing and the classifier accuracy was computed. When the voice features were used alone, an overall classification accuracy of 0.73 was achieved. When age and years of education were additionally used, the overall accuracy increased up to 0.80. These performances were lower than the accuracy of 0.86 found in a recent study. However, in that study the classification was based on several tasks, including more cognitive demanding tasks. Our results are encouraging because acoustic features, derived for the first time only from an ecologic continuous speech task, were able to discriminate people with a normal cognitive function from people with a mild cognitive decline. This study poses the basis for the development of a mobile application performing automatic voice analysis on-the-fly during phone calls, which might potentially support the detection of early signs of functional cognitive decline.

Estimated glomerular filtration rate (eGFR), 25(OH) D3, chronic kidney disease (CKD), the MYH9 (myosin heavy chain 9) gene in old and very elderly people

It is known that the common physiological denominator of the ageing process is an attenuation of functional performance with respect to the situation of young people and adults. However, since the first cohort-based longitudinal studies, it has not been possible to establish a "linear" relationship between age and glomerular filtration in all cases. This does not mean that there is no physiological ageing process at all; in addition to those already elucidated, its mechanisms include cell senescence, podocyte dysfunction, a vitamin D deficiency, and homozygotic forms of the MYH9 gene. The aim of the present work was to analyse the prevalence of chronic kidney disease (CKD) and, where possible, the correlation between CKD, defined by an eGFR < 60 ml/min/1.73 m(2), plasma 25(OH)D3 levels and the MYH9 gene in a population of elderly and very elderly persons. These parameters have not been evaluated previously in populations of elderly and very elderly patients. It is concluded that a moderate decrease in the eGFR occurs with age. This does not imply the presence of CKD in elderly people, since in most individuals the reduced eGFR is not accompanied by anaemia, and no individuals show hypocalcaemia, hyperphosphataemia or a high Alb/Cr ratio. Here we observed a lower Hb level and an elevated Alb/Cr ratio in subjects heterozygotic for the MYH9 gene. This could be interpreted in the sense that the gene could exert some protective effect on renal function, whereas the heterozygotic form (allele A) of the MYH9 gene could be considered a very early marker, a new risk factor for the appearance of CKD, or a sign of renal frailty in elderly people.

Gait analysis of myopathic children in relation to impairment level and energy cost

The electromyographic and kinematic patterns of gait and its energy cost were studied in 12 myopathic patients who were still walking and 12 normal subjects. On the basis of significant gait variables, three distinct levels of impairment were defined in the group of myopathic subjects: early, intermediate and final. These clusterings were predicted with 95.7% accuracy by two gait variables: the stance phase duration and the heel vertical excursion. The gait patterns of each group were compared to the control group. Reduced speed and range of motion, short stride length, small foot-floor clearance, increased energy cost and lateral displacements of centre of gravity were typical and increased with the muscular weakness. The activation of soleus muscle occurred progressively earlier as did the cessation of tibialis anterior activity. In severe disorders, there was increased activity in the muscles acting on the hip and knee. When muscular dystrophy leads to more disability the myopathic patients tended to change from the normal plantigrade gait pattern to an infantile digitigrade-like pattern with a decrease of the tibialis anterior muscle work.

Citrus mealybug (Hemiptera: Pseudococcidae) movement and population dynamics in an arbor-trained vineyard

The citrus mealybug, Planococcus citri (Risso) (Hemiptera: Pseudococcidae), is the main grapevine pest in vineyards in some countries, such as Spain and Brazil. In Galician vineyards (northwestern Spain), mealybug population levels are low because the accumulated degree-days are lower than in other grapevine-growing areas. The main problem caused by mealybugs is the transmission of viruses, even at low infestation levels. The active period of citrus mealybug in the study vineyard lasted from July until December, with an important movement peak at the end of July and August and a lower peak in November. The mealybug mainly moved upward along arbor-trained plants, and there were no important downward movements at the end of the season as has been described for other grapevine mealybugs. The mealybugs were normally restricted to the woody organs and were only present on leaves, branches, and green canes (always close to woody parts) in plants with high infestations. The movement of mealybugs between plants does not seem to take place by contact between green organs. Passive aerial transport and movement of pruning remains may play an important role in mealybug movement and thus in spread of the virus. The number of mealybugs carrying Grapevine leafroll-associated virus 3 (GLRaV-3) was found to represent approximately 75% of mealybugs caught in a GLRaV-3 infected vineyard.

Outcomes from studies of antineutrophil cytoplasm antibody associated vasculitis: a systematic review by the European League Against Rheumatism systemic vasculitis task force

OBJECTIVES

We undertook a systematic literature review as a background to the European League Against Rheumatism (EULAR) recommendations for conducting clinical trials in anti-neutrophil cytoplasm antibody associated vasculitis (AAV), and to assess the quality of evidence for outcome measures in AAV.

METHODS

Using a systematic Medline search, we categorised the identified studies according to diagnoses. Factors affecting remission, relapse, renal function and overall survival were identified.

RESULTS

A total of 44 papers were reviewed from 502 identified by our search criteria. There was considerable inconsistency in definitions of end points. Remission rates varied from 30% to 93% in Wegener granulomatosis (WG), 75% to 89% in microscopic polyangiitis (MPA) and 81% to 91% in Churg-Strauss syndrome (CSS). The 5-year survival for WG, MPA and CSS was 74-91%, 45-76% and 60-97%. Relapse (variably defined) was common in the first 2 years but the frequency varied: 18% to 60% in WG, 8% in MPA, and 35% in CSS. The rate of renal survival in WG varied from 23% at 15 months to 23% at 120 months.

METHOD

used to assess morbidity varied between studies. Ignoring the variations in definitions of the stage of disease, factors influencing remission, relapse, renal and overall survival included immunosuppressive therapy used, type of organ involvement, presence of ANCA, older age and male gender.

CONCLUSIONS

Factors influencing remission, relapse, renal and overall survival include the type of immunosuppressive therapy used, pattern of organ involvement, presence of ANCA, older age and male gender. Methodological variations between studies highlight the need for a consensus on terminology and definitions for future conduct of clinical studies in AAV.

Anti-Sia-lb (anti-Gd) cold agglutinins bind the domain NeuNAc alpha2-3Gal in sialyl Lewis(x), sialyl Lewis(a), and related carbohydrates on nucleated cells and in soluble cancer-associated mucins

Anti-Sia-lb (formerly anti-Gd) cold agglutinins (CAs) recognize sialylated carbohydrates on both adult and neonate red blood cells (RBCs). RBC CA activity inhibition experiments reported here indicate that the domain NeuNAc alpha2-3Gal, as found in sialyllactose, synthetic sialyl(s) Lewis(Le)(x) and sLe(a), sialyllactosamine, sialyl-fucosyllactose, and nonfucosylated sLe(a), constitutes the minimal epitope for these CAs, implicating that these autoantibodies could be able to bind this domain in sLe(x) and sLe(a) and related carbohydrates expressed on nucleated cells and in soluble cancer-related mucins. The following data obtained with the previously characterized monoclonal IgMk anti-Sia-lb CA, GAS, show that this is the case. GAS epitope expression among leukocytes that lack sLe(a) parallels that of sLe(x) determinant as detected by mouse monoclonal antibodies (MoAbs), especially MoAb KM-93. It is also found on epithelial malignant cells bearing both sLe(x) and sLe(a). GAS epitope on these nucleated cells, (1) like that present on RBC, is abolished by sialidase, unaffected by proteases, and inhibited by sialyllactose; and (2) is overlapping and/or proximal to that recognized by anti-sLe(x) MoAb, CSLEX-1, and KM-93. Moreover, CAGAS binds soluble cancer-associated mucins bearing sLe(x) and sLe(a) determinants. This binding is inhibited by sialyllactose and these mucins inhibit the RBC CA activity of CAGAS. The possible significance of anti-Sia-lb (anti-Gd) CAs as autoantibodies directed to carbohydrate ligands of host adhesion molecules that might be receptors of microbial adhesins of some CA-inducing pathogens is discussed.

Penicillin-resistant Streptococcus pneumoniae endophthalmitis

PURPOSE

To report a case of trabeculectomy-associated endophthalmitis caused by penicillin-resistant Streptococcus pneumoniae.

METHOD

Case report.

RESULTS

The patient developed endophthalmitis 1 month after an uncomplicated trabeculectomy for primary open-angle glaucoma. Vitreous cultures grew abundant, highly penicillin-resistant S pneumoniae. Despite aggressive treatment with vitrectomy and intravitreal injections of vancomycin hydrochloride and amikacin sulfate, the patient had a poor visual outcome.

CONCLUSION

Penicillin-resistant S pneumoniae can cause endophthalmitis after trabeculectomy.

Three-dimensional analysis of the angular momentum of a pole-vaulter

A method to determine the three orthogonal components of the angular momentum of a human body about its center of gravity is applied to the pole-vault. The angular momentum and the pole force are used in the analysis of pole-vaulting and are also compared with Gros's data (1982, Ph.D. thesis, University of Alberta) and Hubbard and Barlow's results (1980, Proc. Biomechanics Symp. Indian State Board of Health, pp. 33-48). This study tries to show how such results can be useful in many sporting activities and are necessary for optimization of athletic movement.

[Magnitude and declared causes of absenteeism for health reasons among faculty and students of a medical school]

All sick leaves during 1989 among academics and students of a Faculty of Medicine were analyzed. Twenty three percent of academics and 60.5% of students had at least one sick leave during the year. The mean general rate of absenteeism among academics was 3.55% (1.6% among men and 8.09% among women). The mean length of sick leaves was 13.5 days. Eighteen percent of lost working days were due to pregnancy, lactation or care needs of less than one year children. Tumors, trauma, respiratory, digestive and mental illnesses accounted for 72.8% of lost working days. Medical students had a mean general absenteeism rate of 2.66% (ranging between 1.8% among male sixth year and 4.8% among female fourth year students). Mean length of sick leaves was 3.5 days (ranging from 2.98 among female fifth year and 6.7 among male sixth year students). Respiratory, digestive and infectious diseases accounted for 74% of lost days. No sick leaves were observed, due to pregnancy or lactation among students or due to occupational diseases among academics.

[Severe accidental hypothermia: rewarming by total cardiopulmonary bypass]

We present a case of a 20-year-old male with a history of habitual drug use who suffered extreme hypothermia (26 degrees C) after several hours' accidental exposure to low ambient temperature. The patient presented in deep coma with recurring ventricular fibrillation that yielded to electrical defibrillation once a central temperature of 27.4 degrees C was reached through internal rewarming with intravenous liquids and gastric lavage with warm water. Because this method was slow, we decided to continue rewarming with extracorporeal circulation through cannulation of the femoral vein and artery. The patient recovered consciousness after three hours, with no neurological secuelae. Emergency room staff have available the means for recognizing hypothermia and a protocol for its management. Extracorporeal circulation is an effective method for internal rewarming and must be used when the patient requires cardiopulmonary resuscitation or presents signs of severe hemodynamic instability.

[Design of an expert system for decision-making in an emergency situation]

OBJECTIVES

To study the clinical applicability of the expert system URGSANT as a help in making up decisions in emergencies.

MATERIAL AND METHODS

URGSANT is an expert system implemented in INSIGT 2+ which is structured in a modular and hierarchical form. It contemplates 44 urgent situations relating to the central nervous system, hematopoietic, cardiovascular, respiratory, gastrointestinal, genitourinary, endocrinological, and miscellaneous group. Validation of the program was made by four anesthesiologists who evaluated the performance of the program in 25 emergency cases and in 25 other situations that were treated by other specialists.

RESULTS

The rationale of the system was basically correct. In most cases the program was considered efficient or very efficient during the different clinical situations and only in one case its guidance was wrong.

CONCLUSIONS

The URGSANT expert system is an efficient and useful method for the clinician during emergency situations.

[Tracheal rupture during a transhiatal esophagectomy without thoracotomy. Intra- and postoperative treatment]

We report the case of a male patient with a carcinoma of the upper third of the esophagus who presented a tracheal rupture during a transhiatal esophagectomy. The clinical picture was characterized by a severe alteration of the ventilatory function that required selective intubation and, later on, a right thoracotomy for repairing the tracheal lesion. After surgery the patient was treated at the Recovery Unit. He received high-frequency mechanic ventilation (jet ventilation type) during nine days in a attempt to decrease the risk for dehiscence of the tracheal suture and to ensure an adequate oxygenation and hemodynamic control. The clinical course was favourable.

[Doctoral theses and memoirs about anesthesia. Documents for a history of Spanish anesthesia]

Based on the importance of document files and first-hand bibliographic sources for studying the history, we have recently investigated the chapter of Doctoral Thesis and Reports on anesthetic topics since we believe that these are fundamental to gain insight into the knowledge of our history. This investigation was planned to find such documents by reviewing the data of several Spanish archives and libraries. We collected 80 works: 14 Reports and 66 Doctoral Theses performed during a period of 95 years (heuristic limits 1847-1942). These papers were classified in several subgroups according to the subjects they deal with: 21 works on inhalation anesthesia, 7 on intravenous general anesthesia, 20 on spinal anesthesia, 10 on locoregional, 7 on anesthesia and metabolism, 12 on obstetric anesthesia, and 3 works on varied anesthesia issues. Analysis of these documents revealed that the authors (physicians and Spanish medical corporations) undertook an accurate consideration of the more relevant scientific subjects at the time of their investigation. We conclude that the works analyzed in the present study represented the beginning of the Spanish investigation on anesthesia. Further investigations may contribute to enrich our historiography.

Polyarteritis nodosa confined to calf muscles

Two patients who developed pain and tenderness in their calf muscles, without other organ system involvement, are described. A gastrocnemius biopsy disclosed necrotizing muscular arteritis. Five other reported cases are reviewed and we conclude that there is a limited form of polyarteritis nodosa localized to calf muscles, with a differentiated and more benign clinical course, a differential diagnosis restricted to local pathological processes and prompt response to treatment with corticosteroids alone.
