RESUMEN

Background and objectives: Mechanical ventilation is often used in intensive care units to assist patients' breathing. This often leads to respiratory muscle weakness and diaphragmatic dysfunction, causing weaning difficulties. Inspiratory muscle training (IMT) has been found to be beneficial in increasing inspiratory muscle strength and facilitating weaning. Over the years, different protocols and devices have been used. Materials and Methods: The aim of this systematic review and meta-analysis was to investigate the effectiveness of low-medium (LM-IMT) and high-intensity (H-IMT) threshold inspiratory muscle training in critically ill patients. A systematic literature search was performed for randomized controlled trials (RCTs) in the electronic databases Google Scholar, PubMed, Scopus, and Science Direct. The search involved screening for studies examining the effectiveness of two different intensities of threshold IMT in critically ill patients published the last 10 years. The Physiotherapy Evidence Database (PEDro) scale was chosen as the tool to assess the quality of studies. A meta-analysis was performed where possible. Results: Fourteen studies were included in the systematic review, with five of them having high methodological quality. Conclusions: When examining LM-IMT and H-IMT though, neither was able to reach statistically significant improvement in their maximal inspiratory pressure (MIP), while LM-IMT reached it in terms of weaning duration. Additionally, no statistical difference was noticed in the duration of mechanical ventilation. The application of IMT is recommended to ICU patients in order to prevent diaphragmatic dysfunction and facilitate weaning from mechanical ventilation. Therefore, further research as well as additional RCTs regarding different protocols are needed to enhance its effectiveness.

RESUMEN

The purpose of this study was to investigate psychometric properties of the Greek translation of Pittsburgh Sleep Quality Index (GR-PSQI) in a Greek chronic non-specific low back pain (CNSLBP) sample, thus, providing insight on its clarity and acceptability as a widely used sleep assessment tool in clinical practice. Asymptomatic volunteers (n = 73) and CNSLBP volunteers (n = 47), participated in the study. For the assessment of construct validity, the known-groups method was used. Thus, all the participants (asymptomatic and CNSLBP) completed the GR-PSQI. For the assessment of concurrent validity, the CNSLBP participants additionally completed the following validated questionnaires for depression, insomnia and sleep quality: Beck Depression Inventory Questionnaire (BDI), Insomnia Severity Index (ISI), and Sleep Quality Numeric Rating Scale (SQNRS). For the assessment of test-retest reliability, the CNSLBP participants completed the GR-PSQI a second time, one week after the first time. The results showed excellent test-retest reliability (ICC = 0.969, SEM = 0.90, SDD = 2.49%) and internal consistency (Cronbach α = 0.985), moderate to good concurrent validity (from r = 0.556 to r = 0.860) among PSQI, BDI, SQNRS, and ISI, as well as excellent construct validity (p = 0.000) between the two groups. The Greek translation of PSQI could be a valuable tool for Greek healthcare professionals in both clinical and research environments.

RESUMEN

PURPOSE: To examine the effectiveness of Neuromobilization Exercises (NE) on pain, grip and pinch strength, two-point discrimination, motor and sensory distal latency, symptom severity, and functional status using the Boston Carpal Tunnel Questionnaire (BCTQ) in Carpal Tunnel Syndrome (CTS). METHODS: Major electronic databases were searched from inception up to September 2021 for randomized trials comparing the effects of NE with or without other interventions against no treatment, surgery, or other interventions in patients with CTS. Standardized Mean Differences (SMD) and 95% confidence interval (CI) were calculated using a random-effects inverse variance model according to the outcome of interest and comparison group. Methodological quality was assessed with PEDro and quality of evidence with the GRADE approach. RESULTS: Twenty-five articles were included and sixteen of them demonstrated high methodological quality. NE was superior to no treatment on pain (very low-quality evidence; SMD = -2.36, 95% CI -4.31 to -0.41). NE was superior to no treatment on the functional scale of the BCTQ (low-quality evidence; SMD = -1.27 95% CI -1.60 to -0.94). Most importantly, NE did not demonstrate evidence of clinical effectiveness. CONCLUSION: Low to very low-quality evidence suggests that there are no clinical benefits of NE in patients with mild to moderate CTS.

RESUMEN

OBJECTIVE(S): The purpose of the study was to review patients' characteristics and the location of extrapelvic endometriosis. STUDY DESIGN: Out of 1000 women with endometriosis during a 20year period, we found 200 cases with extra pelvic endometriosis. Medical reports were evaluated and the diagnosis was confirmed on the pathological specimen. This study involved cases from two different geographical areas, New Haven and Crete. The age, parity, symptoms, previous surgeries, diagnostic modalities, histopathological evaluation and location of endometriotic implants found in other areas were recorded and analyzed from the patient's charts. MAIN OUTCOME MEASURE(S): Statistical methods included x2 and Mann-Whitney U test s measuring incidence of right-VS left sided endometriosis. RESULTS: 200 patients with extrapelvic endometriosis and 800 patients with pelvic endometriosis were included in the study. The gastrointestinal tract represents the most common location of extrapelvic endometriosis with 104/200(52%) cases (p<0, 01), followed by the urinary system with70/200(35%) cases. We observed the Left-sided ureter being involved in 49/200(24, 5%) cases, significantly higher compare with the right-sided ureter 21/100(10, 5%) (p <0, 01). All women had similar characteristics involving age, weight, main complaints, age of menarche, endometriosis stages, gravid and family history of endometriosis. CONCLUSION(S): The gastrointestinal tract and the urinary system are the most common sites of the extrapelvic endometriosis, which was obvious in both countries. Moreover, we observed that there are no significant differences in demographic variants, menstrual and reproductive characteristics in women with extrapelvic and pelvic endometriosis.

RESUMEN

A group of 140 women with a body mass index (BMI) < or = 24 kg/m(2) undergoing 291 cycles was compared with a group of 138 women with a BMI >24 kg/m(2) in 291 cycles, with respect to duration of ovarian stimulation and dose of gonadotrophin, number of oocytes collected, cleavage and implantation rate, clinical pregnancy, miscarriage and delivery rates. Patients with a BMI > 24 kg/m(2) demonstrated a significant decrease in the number of follicles after stimulation (P = 0.01), a comparative increase in the number ampoules of gonadotrophin used (P = 0.03) and a lower number of eggs collected (P = 0.05). The mean number of embryos on days 1, 2 and 3 was significantly lower in the group with BMI > 24 kg/m(2) (P < 0.001). No significant difference was found in clinical pregnancy and miscarriage rates between the two groups. In spite of the lower response in women with BMI > 24 kg/m(2), the delivery rate per retrieval was not different (24.6 versus 24.8%). These results indicate a lower stimulation response in women with elevated BMI, but no adverse effect on IVF outcome. In relation to wellbeing, however, it is recommended that patients with a high BMI reduce their weight before IVF treatment.

RESUMEN

OBJECTIVE: Few studies examining the association of endometriosis with the risk of breast cancer. Our goal was to investigate the familial risk of breast cancer in women with endometriosis. DESIGN: Retrospective study. SETTING: University-based endometriosis referral center. PATIENTS: Three hundred fifty-two women with endometriosis and 180 infertile women without endometriosis were studied using laparoscopy between August 1996 and February 2002. The endometriosis group was further subdivided into a group of women with 94 positive and 268 negative family histories of breast cancer. MAIN OUTCOME MEASURE(S): The overall risk of familial breast cancer among first- and second-degree relatives in patients with endometriosis and the association between potential risk factors was estimated by chi(2) and by crude adjusted odds ratios (95% CI). RESULTS: Positive family history of breast cancer was detected in (26.7%) 94/352 of endometriosis group and in (5%) 9/180 of controls. The relative risk of women with endometriosis and positive family history of breast cancer was (OR=6.9 (95% CI, 3.4-14.1), chi(2)=34.6, P<0.001). Endometriosis was associated with the risk of first-degree relatives of breast cancer (OR=5.69 (95% CI, 2.4-13.3), P<0.001). Moreover, endometriosis was significantly associated with the risk of breast cancer in mothers (OR=6.3 (95% CI, 2.2-17.8), P<0.001) and in maternal aunts (OR=5.9 (95% CI, 1.3-72.9), P<0.001). The two groups are similar in age, race height, main complaints, age of menarche, cycle length, days of flow, estimated blood loss, stage of endometriosis and the presence of endometrioma. CONCLUSION(S): This study found an elevated risk associated with family history of breast cancer among women with endometriosis. A familial clustering interaction with a familial history of breast cancer in women with endometriosis is possible, but should be investigated further.

RESUMEN

OBJECTIVE: To investigate the familial aggregation and the risk of endometriosis among the female relatives of women with endometriosis. We also compared the epidemiologic characteristics of women with and without family history of endometriosis. PATIENT(S): A total of 485 women with endometriosis and 197 infertile women without endometriosis underwent surgical investigation between August 1996 and February 2002. MAIN OUTCOME MEASURE(S): The relative risk of endometriosis in a first-degree relative and the association between potential risk factors was estimated by chi2 and by crude adjusted odds ratios (95% CI). RESULTS: Endometriosis was identified in 9.5% of first-degree relatives of women with endometriosis versus only 1% of controls. The odds ratio for endometriosis in a first-degree relative was 10.21 (95% CI 2.45-42.5; P<0.001). In 3.9% of cases women with endometriosis reported that their mother had been diagnosed with endometriosis and 5.6% of cases that at least one sister had been diagnosed. Compared to the control group the odds ratio for the mother having endometriosis (7.99, 95% CI 1.06-60.1) or at least one sister having (11.55, 95% CI 1.56-85.59) were significantly elevated. Among women with endometriosis who reported a family history of endometriosis, and women with endometriosis who did not report a family history of endometriosis, there were no differences in demographic characteristics, body habitus, or menstrual parameters. CONCLUSION(S): Women with endometriosis have a tenfold increased risk of endometriosis in their first-degree relatives.

RESUMEN

OBJECTIVE: To quantify levels of macrophage migration inhibitory factor (MIF) in the peritoneal fluid (PF) of women with endometriosis, and to correlate these levels with the extent of disease. DESIGN: Controlled clinical study. SETTING: Academic medical center. PATIENT(S): Peritoneal fluid samples were collected during laparoscopic surgery in 60 women with endometriosis and 16 controls undergoing tubal ligation; 52 of the women with endometriosis had received no hormonal treatment in the 6 months prior to surgery, while 8 were using gonadotropin-releasing hormone (GnRH) agonists. MAIN OUTCOME MEASURE(S): Peritoneal fluid migration inhibitory factor (PF MIF) levels. RESULT(S): Women with endometriosis had significantly higher PF MIF levels (10.8 +/- 0.9 ng/mL) than controls (3.0 +/- 0.7 ng/mL). However, no correlation existed between MIF levels and the stage of disease (r = 0.05) or the depth of endometriotic invasion (r = 0.08). Moreover, treatment with a GnRH agonist did not suppress PF MIF levels. Peritoneal fluid MIF levels did not vary significantly between the proliferative and secretory phases of the cycle, and did not distinguish women with endometriosis-associated infertility from women with endometriosis-associated pain. CONCLUSION(S): Peritoneal fluid migration inhibitory factor levels are markedly elevated in women with endometriosis but are independent of the extent of disease.

RESUMEN

OBJECTIVE: Peritoneal fluid (PF) inflammatory factors may participate in the pathogenesis of endometriosis. The aim of this study was to investigate PF interleukin (IL)-18 levels in women with and without endometriosis. DESIGN: Controlled clinical study. SETTING: Women undergoing laparoscopy at a university hospital. PATIENT(S): Fifty women with previously untreated endometriosis, 8 women on GnRH agonists for endometriosis, and 18 control women with normal pelvic anatomy who were undergoing tubal ligation. INTERVENTION(S): Peritoneal fluid IL-18 levels as measured by ELISA. MAIN OUTCOME MEASURE(S): Peritoneal fluid IL-18 levels. RESULT(S): Peritoneal fluid IL-18 levels were significantly higher in women with previously untreated endometriosis (mean +/- SEM, 91.1 +/- 6.5 pg/mL) than in control women (59.4 +/- 2.0 pg/mL). Interestingly, women with superficial (100.0 +/- 10.2 pg/mL) and deep peritoneal implants (94.0 +/- 10.8 pg/mL) had significantly higher PF IL-18 levels than did women with endometriomas (57.8 +/- 1.8 pg/mL). Similarly, women with stage I-II endometriosis (97.3 +/- 8.0 pg/mL), but not women with stage III-IV endometriosis (74.9 +/- 9.9 pg/mL), had significantly higher PF IL-18 levels than did control women. Peritoneal fluid IL-18 levels were significantly higher in the luteal phase than in the follicular phase but did not discriminate between women with pelvic pain or infertility. CONCLUSION(S): Peritoneal fluid IL-18 is elevated in women with peritoneal, minimal- to mild-stage endometriosis.

RESUMEN

PROBLEM: Pregnancy-associated plasma protein-A (PAPP-A) belongs to a group of glycoproteins isolated from extracts of human placenta. Healthy ovarian and uterine tissues are also known to express PAPP-A. We hypothesized that PAPP-A levels might also be elevated in the peritoneal fluid (PF) of women with endometriosis, and examined variations in PF PAPP-A during the menstrual cycle and with the severity of the disease. METHOD OF STUDY: PF PAPP-A were measured in 60 women with endometriosis and 38 women without endometriosis using a high-sensitivity immunofluorometric assay. RESULTS: We found that the mean level of PAPP-A was higher in PF from patients with endometriosis than controls (p = 0.003). Furthermore, significant correlation was found between the stages of endometriosis and the levels of PAPP-A in these patients (r = 0.39, p = 0.009). The concentrations of PAPP-A in PF were significantly higher in the secretory phase than the proliferative phase of the menstrual cycle in both women with and without endometriosis (p = 0.009 and P = 0.002, respectively). Finally, among the controls, women undergoing tubal ligation had significantly lower mean PF levels of PAPP-A than women with infertility or pelvic pain (p = 0.001). CONCLUSION: We conclude that PF levels of PAPP-A vary during the menstrual cycle, and are highest in the secretory phase. We also find that PF PAPP-A levels are significantly increased in women with endometriosis, and that the degree of elevation corresponds to the extent of disease.

RESUMEN

BACKGROUND: The role of leptin in reproductive processes has received increasing attention. Because leptin has intrinsic angiogenic properties, may be induced by inflammatory cytokines and induces matrix metalloproteinases, we examined peritoneal fluid (PF) leptin concentrations in women with endometriosis. METHODS: PF samples were collected from 60 women undergoing laparoscopy for endometriosis, and 18 controls undergoing tubal sterilization. Fifty of the women with endometriosis had received no prior hormonal treatment, while 10 with moderate- severe endometriosis were using GnRH agonists. RESULTS: Women with untreated endometriosis had significantly higher (mean +/- SD) PF leptin levels (34.9 +/- 7.9 ng/ml) than controls (17.9 +/- 4.1 ng/ml; P < 0.001). However, PF leptin levels were inversely correlated with the stage of disease (r = -0.62; P < 0.001). Nevertheless, women with stage III-IV endometriosis maintained significantly higher PF leptin levels (26.3 +/- 4.8 ng/ml; P < 0.001) than controls. Although PF leptin levels were significantly higher in the secretory versus proliferative phase of the menstrual cycle, they remained higher in both phases in women with untreated endometriosis. PF leptin levels in women on GnRH agonists were similar to controls. CONCLUSIONS: PF leptin levels are elevated in women with endometriosis, but inversely correlated with extent of disease. These findings suggest a potential role for leptin in the pathogenesis of peritoneal endometriosis.

RESUMEN

OBJECTIVE: To investigate the possibility of genetic contribution of CYP1A1, CYP19, GSTM1, and GSTT1 polymorphisms to endometriosis. DESIGN: Genetic polymorphism analysis. SETTING: Case-control study. PATIENT(S): A group of 275 women with sporadic endometriosis was compared with a group of 346 fertile, endometriosis-free women. INTERVENTION(S): Surgical, laparoscopic, and histological examination. MAIN OUTCOME MEASURE(S): Blood specimens were obtained from endometriosis cases and controls. Polymerase chain reaction-based assays were performed for the determination of individual's genotype. RESULT(S): The CYP19 VNTR, located in intron 4 (TTTA)(10) allele increases the risk for endometriosis development (odds ratio [OR], 4.99; 95% confidence interval [95% CI], 1.351 to 18.436). The combined genotype CYP1A1 wt/m1 or m1/m1 and GSTM1 null deletion adds to this risk (OR, 1.95; 95% CI, 1.266 to 2.995 and OR, 2.23; 95% CI, 0.631 to 7.906, respectively). In contrast, the CYP1A1 wt/wt genotype exhibits a protective effect, with a 38% reduction in the odds for endometriosis development (OR, 0.62; 95% CI, 0.440 to 0.883). CONCLUSION(S): Our data suggest that CYP19 VNTR (TTTA)(10) allele as well as the combined genotype CYP1A1 m1 polymorphism and GSTM1 null deletion associate with the endometriosis phenotype, whereas the GSTT1 null deletion does not.

RESUMEN

BACKGROUND: Interleukin (IL)-15 is a novel cytokine with immunoregulatory and angiogenic properties. We compared IL-15 levels in the peritoneal fluid (PF) of women with and without endometriosis. METHODS: PF samples were obtained from 55 women with endometriosis (23 with superficial peritoneal implants, 19 with deep endometriotic implants and 13 with ovarian endometriomas). Eighteen women with normal pelvic anatomy undergoing tubal sterilization served as controls. RESULTS: PF IL-15 concentrations were increased in women with endometriosis (2.7 +/- 0.5 pg/ml) versus controls (2.1 +/- 0.3 pg/ml; P < 0.001). However, IL-15 levels were higher in women with superficial peritoneal implants (2.9 +/- 0.5 pg/ml) than women with deep endometriotic implants (2.6 +/- 0.4 pg/ml; P = 0.01) or ovarian endometriomas (2.2 +/- 0.4 pg/ml; P < 0.001). IL-15 was also higher in women with deep implants than in those with endometriomas (P < 0.05). PF IL-15 correlated inversely with both depth of invasion (r = -0.52) and the stage of endometriosis (r = -0.42). PF IL-15 levels demonstrated little variation during the menstrual cycle, and did not discriminate between women with infertility or pelvic pain. CONCLUSION: PF IL-15 levels are increased in women with endometriosis. However, IL-15 levels are inversely correlated with the depth of invasion and disease stage, suggesting a possible role for this cytokine in the early pathogenesis of endometriosis.

RESUMEN

The relationship between metabolism and reproduction remains a mystery in female endocrinology. Such substances as insulin, amino acids and IGFBP-I have been proposed as signals of body mass fat on the genital axis. Today this role is claimed by leptin, a protein hormone decoded from the obesity gene and is secreted exclusively from adipose tissue. This hormone acts on the central nervous system (CNS) to result in the suppression of food intake and increase in energy consumption. What is more, it also influences the capacity for reproduction. This paper reports findings with regard to the factors influencing the secretion of leptin and identification of the leptin's hormonal receptors. Particular emphasis was placed on the relationship between secretion of leptin and disturbances in menstruation, the anticipated role of this hormone in the pathogenesis of the polycystic ovarian syndrome (PCOS) and its effects on the reproductive capacity.

RESUMEN

To report two rare cases of gonadotropin-resistant ovary syndrome associated with secondary amenorrhea and normal levels of inhibin B. Case report. Two university teaching hospitals. Two women presenting with secondary amenorrhea and infertility. The control group for the inhibin B levels consisted of 30 cycling women of reproductive age. Medical history, physical examination, laboratory data, histologic findings, and IVF results. Diagnosis and treatment of resistant ovary syndrome. Case 1 was a 25-year-old woman with secondary amenorrhea and primary infertility. She had high serum levels of FSH and LH, low E(2) levels, and normal inhibin B levels (62 pg/mL). Karyotype was 46,XX, and ovarian biopsy showed primordial follicles with oocytes. Administration of GnRH analogue with hMG for 15 days did not affect E(2) levels. She had a successful pregnancy with IVF using donor oocytes. Case 2 was a 24-year-old woman with secondary amenorrhea. She had elevated serum levels of FSH and LH, low E(2) levels, and normal inhibin B levels (57 pg/mL). Karyotype was 46,XX and ovarian biopsy showed primordial follicles. Administration of GnRH analogue with hMG for 12 days did not affect E(2) levels. Both women were given estrogen-progestin replacement therapy. Inhibin B has a diagnostic role in women with gonadotropin-resistant ovary syndrome associated with secondary amenorrhea. A review of the literature confirms the uniqueness of the diagnostic role of inhibin B in these cases.

RESUMEN

PROBLEM: The objective of this study was to evaluate the possible relevance of cytokines in seminal plasma (SP) of patients with accessory gland infection and oligoterato-asthenozoospermia. METHOD OF STUDY: Semen samples were obtained by masturbation from 90 men and were examined for the presence of interleukin (IL)-2, IL-6, IL-8, IL-11 and soluble CD23 (sCD23) by enzyme-linked immunosorbent assay. Five groups were included: (1) fertile men (n = 20), (2) infertile men with varicocele and oligo-teratoasthenozoospermia (V-OTA, n = 20), (3) infertile men with genital infection and OTA (INF-OTA, n = 20), (4) infertile men with idiopathic testicular lesion and OTA (ITL-OTA, n = 20) and (5) infertile men with azoospermia (AZOO, n = 10). RESULTS: We found that the mean level of IL-2 was higher in SP from infertile men compared with SP from fertile men (P < 0.05). Mean levels of IL-6, IL-8, IL-11 in SP of INF-OTA were higher than that of all other groups (P < 0.05, P < 0.05, P < 0.001, respectively). However, no significant differences could be detected between other groups. A significant increase was noted in sCD23 levels in SP from men with ITL-OTA compared with all other groups (P < 0.01). We have not observed any correlations between IL-2, IL-6, IL-8, IL-11 and sCD23 levels in SP and semen parameters. Spearman's correlation coefficient revealed that there was a significant association between IL-6, IL-8, IL-11 levels in men with INF-OTA. CONCLUSION: The measurement of each cytokine separately in the SP of men with INF-OTA, in spite of the existing significant differences, does not have a diagnostic value in male infertility. However, a combined determination of IL-6, IL-8, IL-11 in the SP of men with genital infection and oligo-terato-asthenozoospermia may provide clinically useful information for the diagnosis of male accessory gland infection.

RESUMEN

OBJECTIVE: To report a rare case of a patient with catamenial hemoptysis, secondary infertility, and endometriosis associated with a unicornuate uterus and noncommunicating rudimentary horn. DESIGN: Case report. SETTING: University hospital. PATIENT(S): A 29-year-old woman who developed progressive catamenial hemoptysis and secondary infertility was evaluated at the University Hospital of Crete. INTERVENTION(S): The complete history, laboratory data, laparoscopic findings, and chest magnetic resonance image of this patient were analyzed. A GnRH agonist, leuprolide acetate, was successfully administered. MAIN OUTCOME MEASURE(S): Diagnosis and appropriate treatment of pulmonary endometriosis in a patient with rudimentary uterine horn. RESULT(S): Treatment with a GnRH agonist achieved suppression of both menstruation and hemoptysis. After 6 months of normal menstrual activity, the symptoms reappeared. The patient was again treated with leuprolide acetate (3.75 mg/mo IM) for 6 months and remained asymptomatic. In fact, the patient became pregnant after cessation of therapy. Finally, the patient was treated successfully with removal of the rudimentary uterine horn during cesarean section. Three-year follow-up showed disappearance of the chest symptoms. CONCLUSION(S): Pulmonary endometriosis and unicornuate uteri are rare. To our knowledge, this is the first case of catamenial hemoptysis with a congenital müllerian anomaly. We describe successful management using a combination of GnRH agonist and surgical resection of the rudimentary uterine horn.
