External load metrics and monitoring in women's football match play: A systematic review.

This systematic review aimed to identify the most commonly used variables for monitoring external load during elite women's football matches and to compare reporting practices internationally and in Brazil. Searches were conducted in Web of Science, PubMed, and SciELO using the PICOS framework between February and March 2026, resulting in the inclusion of 35 studies. The main outcomes analysed were total distance covered (TD), distance covered across speed zones (HSR, VHSR, sprint), number of accelerations and decelerations, and maximum speed. TD and distance covered across speed zones were the most frequently reported indicators (94.3%), followed by HSR (82.8%) and sprint distance (68.5%). Considerable variability was observed in the classification of speed zones and thresholds used to define accelerations and decelerations, limiting comparisons between studies. External load values varied according to playing position and competition level, with international matches generally imposing greater demands than national competitions. Brazilian research remains limited and demonstrates notable methodological variability. This review proposes standardised speed and acceleration/deceleration thresholds based on the most recurrent ranges reported in the literature, supporting improved consistency in monitoring practices across elite women's football contexts.

Twenty-four-hour recording in REM-narcoleptics with special reference to nocturnal sleep disruption.

Twenty narcoleptic patients and ten age-matched normals were polygraphically monitored for 58 consecutive hours. All subjects were on regimented sleep (hours between 2230 and 0700). Group A (11 patients and 10 normals) had enforced wakefulness during the day whereas Group B (9 patients) were permitted to sleep (mean = 2 1/2 hr.). On day 2, all subjects were permitted to sleep for 15-min periods every 2 hr. In narcoloptics, sleep recordings demonstrated a reduction of sleep latency, an increase of stage 1, and a decrease in stages 3 and 4 compared to normals, but total REM time and percentage of REM sleep were similar. Groups A and B showed no difference in the incidence of nocturnal awakenings. REM cyclic periodicity was larger in narcoleptics who also demonstrated a REM-sleep fragmentation. This fragmentation became more pronounced as time passed, with several shifts from REM to wakefulness and stage 1. Narcoleptics present REM onset sleep period but also show an inability to remain in REM sleep.

A phase II study to evaluate the efficacy of commercially available molecularly matched targeted therapies in the second-line setting.

BACKGROUND: Initial studies have shown improved outcomes in patients receiving cancer therapies matched to their molecular alterations. To improve the chances of finding a therapeutic match for patients, this study evaluated the preliminary antitumor activity of 3 commercially available multitargeted agents in the United States, regorafenib, afatinib, and cabozantinib. METHODS: In this phase II trial, patients who did not benefit from first-line treatment for non-small cell lung cancer (NSCLC), upper aerodigestive tract cancers, non-colon gastrointestinal cancers, and urothelial carcinoma underwent next-generation sequencing to identify actionable genomic alterations. Eligible patients, based on identified mutations deemed treatable by regorafenib, cabozantinib, or afatinib, were enrolled to receive matched targeted therapies. Outcomes were monitored via Response Evaluation Criteria in Solid Tumors criteria, with dose modifications per National Cancer Institute Common Terminology Criteria for Adverse Events, v4.03 guidelines for adverse events (AEs). RESULTS: One hundred patients with metastatic cancers were enrolled across tumor types. Median treatment durations were 12 weeks (regorafenib), 10.7 weeks (afatinib), and 24.1 weeks (cabozantinib). The overall objective response rate was 7.0%, with 1 complete response and 8 partial responses. The clinical benefit rate, including responses and stable disease >6 months, was 16.0%. Median progression-free survival ranged from 1.9 months for urothelial carcinoma to 3.2 months for NSCLC. Toxicities were common for all medications; for regorafenib, 90.7% of patients had AEs (50% Grade 3/4); for afatinib, 86% of patients had AEs (54% Grade 3/4); for cabozantinib, 100% of patients had AEs (36% Grade 3/4). The most common AEs were diarrhea, fatigue, nausea, decreased appetite, and stomatitis. CONCLUSIONS: Regorafenib, afatinib, and cabozantinib had modest effects when used as molecularly matched targeted therapies in patients with NSCLC, upper aerodigestive tract cancers, non-colon gastrointestinal cancers, and urothelial carcinoma in the second-line setting. Future research could examine more precise matching of therapies to genomic alterations and evaluate combination therapies.

Hyperglycemia and glucagon suppression: possible importance of the vagus and enteric humoral factors.

Augmentation of insulin release after oral glucose by a gastrointestinal humoral mechanism is well accepted. The suggestion of a similar mechanism for suppression of glucagon release after oral glucose has not been previously tested. In this study, plasma glucagon levels have been estimated in five normal subjects after both oral and iv administration of glucose. A variable iv glucose infusion rate with frequent monitoring of blood glucose was used to match the hyperglycemia produced by the 50 g oral glucose and the iv glucose loads. Virtually complete suppression of plasma glucagon levels was seen in both cases (nadir of glucagon levels 16 +/- 6 pg/ml for oral glucose; 11.4 +/- 3 pg/ml for iv glucose). Thus, enteric humoral factors did not facilitate glucagon suppression after oral glucose ingestion in man. The vagus nerve is also involved in mediating the alpha-cell response to hypoglycemia and, thus, to examine whether hyperglycemia suppresses glucagon release through a vagal mechanism, iv atropine (15 microgram/kg) was given 20 min before administration of oral or iv glucose. Atropinization delayed the glucagon suppression after oral glucose, but this delay was probably related to delayed glucose absorption from the gut. With iv glucose, atropinization did not affect the degree of suppression of glucagon levels. It is concluded that alpha-cell suppression in response to hyperglycemia is not mediated via the vagus.

Precision Medicine in Transfusion-Dependent and Non-Transfusion-Dependent β-Thalassemia: Toward Personalized Diagnosis and Therapy.

β-thalassemia comprises a clinically heterogeneous group of disorders in which anemia severity, transfusion exposure, iron loading, and organ complications vary widely among individuals. This structured narrative review summarizes practical applications of precision medicine in transfusion-dependent thalassemia (TDT) and non-transfusion-dependent thalassemia (NTDT), with explicit attention to which strategies apply to each clinical category. Literature indexed in PubMed and Scopus from 2000 to 2025 was reviewed using terms related to thalassemia, precision medicine, magnetic resonance imaging (MRI), chelation tailoring, next-generation sequencing (NGS), fetal hemoglobin (HbF) modifiers, luspatercept, mitapivat, hepcidin, gene therapy, gene editing, and artificial intelligence (AI). Evidence was synthesized descriptively because interventions, outcomes, and populations were heterogeneous, and no pooled meta-analysis was performed. In TDT, precision care is centered on individualized transfusion planning, extended red-cell antigen matching, MRI-guided cardiac and hepatic iron monitoring, organ-directed chelation intensification, and selection of disease-modifying or curative approaches. In NTDT, precision care emphasizes accurate phenotype classification, MRI liver iron concentration, because serum ferritin may underestimate iron burden, selective chelation, surveillance for NTDT-specific complications, and individualized use of agents that improve anemia. Personalized chelation should include deferiprone, either alone or in combination, when cardiac iron is increased. Comprehensive molecular diagnosis should include HBB together with HBA1 and HBA2 assessment, while secondary and tertiary modifiers help explain phenotypic variability and complication risk. Hepcidin and growth differentiation factor 15 (GDF-15) are discussed as investigational biomarkers; transferrin saturation is not recommended for routine iron-overload assessment in thalassemia. AI currently has its strongest role in screening and diagnosis, whereas risk-stratification models remain exploratory. Equitable implementation requires standardized TDT/NTDT pathways, regional MRI and genomics access, longitudinal registries, and multidisciplinary interpretation.

Mechanism-Driven Diagnostic Development: A Specimen-Aware Framework Illustrated by Colorectal Cancer and Solid Tumours.

Translational oncology has moved rapidly from histopathology and single-analyte biomarkers toward multi-dimensional molecular profiling. Yet many clinically deployed tests still use reductionist biomarker strategies that under-represent cancer complexity. This review examines whether a mechanistic, multi-layered, and specimen-aware approach can improve cancer detection, classification, prognosis, minimal residual disease (MRD) assessment, and therapeutic selection. Evidence across solid tumours shows that genomic alterations alone incompletely explain tumour state, metastatic behaviour, immune evasion, or therapeutic vulnerability. Integrated genome and transcriptome analyses, proteogenomics, single-cell atlases, fragmentomic, methylation based cell-free DNA assays, metabolomics and microbiome assessments reveal clinically relevant biology that single modality tests cannot determine. Minimally invasive collected specimens can extend access to screening, diagnosis and longitudinal monitoring, but the choice of specimen should be matched to disease biology and analytes that represent mechanisms of oncogenesis. However, translation remains constrained by pre-analytical variability, contamination, differences in tumour shedding behaviour, clonal haematopoiesis, translation of generated models, incomplete external validation and uncertain downstream clinical utility for emerging platforms. This review provides a commentary on the future of cancer diagnostics, the considerations and barriers to clinical translation, the relationship between utility and dimensionality of biomarkers assessed and the emerging rationale towards mechanistically grounded integrated models.

[Miniaturized methods to monitor intracranial pressure. Technical and clinical results (author's transl)].

The prognosis of numerous diseases of the central nervous system is essentially determined by the intracranial pressure (ICP) and its therapeutic influencing. Long-term monitoring of the ICP must therefore be the objective in neurological and neurosurgical patients at risk. For this purpose, miniaturized methods were tested and developed. To monitor the intracranial pressure in patients who were not operated on, a miniature pressure transducer the size of a match head was used which was directly implanted 'percutaneously' in the intensive care unit: After a stab wound had been made in the skin, a 5-mm burrhole is made; the specially constructed miniature coaxial burr which disengages as soon as it touches the dura automatically enables coplanar epidural implantation of the transducer by means of an adapter capsule. The skin is closed without tension. For monitoring the pressure after trepanation, a spiralled miniature pressure transducer is implanted. The equally flattened receiver with lateral membranes is placed intracranially as desired, e.g., epidurally or subdurally, durin the operation. The zero point can be checked from outside without danger of infection. After the end of the measurements the recorder is easily extracted. Up to the present time, the epidural pressure has been reliably monitored for several weeks by this method in 86 patients. Ten comparative measurements showed corresponding cerebrospinal fluid pressures to within a few mm Hg with very good reproduction of frequency and amplitude. Small zero drift and the external zero control give an accuracy of measurement +/- 5 mm Hg independently of the time of measurement. The measurement permits early recognition of progressive intracranial space-occupying lesions. In 14 patients (16%) a measured rise in intracranial pressure was an essential basis for indication for neurosurgical operations. In addition, the pressure measurement provides an objective assessment of the effect of measures to lower the ICP; progressive increases in intracranial pressure which cannot be influenced conservatively can be brought for surgical decompression in good time before the brain has been irreversibly damaged by pressure. In craniocerebral traumata, monitoring the intracranial pressure permits the differentiation of primary damage to the brain stem with uniform, normal intracranial pressure from secondary constrictions of the brain stem with considerable rise of intracranial pressure and disturbed autoregulation. Only in chronic subdural haematomata are considerable displacements of intracranial masses to be seen with only slightly increased ICP ( less than 30 mm Hg). Besides space-occupying lesions, the measurement of pressure also detects generalised epileptic attakcs due to a considerable rise in intracranial pressure caused by hyperemia. Also disorders of respiration are recognised by supervision of ICP. The procedures described seem suitable for routine monitoring of ICP in patients at risk, with little operative effort and minimum danger...

A monitoring study of workers handling pesticides in warehouses and godowns.

Monitoring observations made on 60 operators involved in pesticide application work in godowns and warehouses and 60 matched control workers are reported. Occupational exposure history and medical history are noted. Biochemical investigations, plasma and RBC cholinesterase estimations are included along with medical examination of the workers. Workers were found to be mostly exposed to Celphos, DDVP, Malathion, Pyrethrum, etc, and the use of protective devices were very limited. Cases of significant reduction in plasma and RBC cholinesterase activity were found. Frequency of symptoms like dizziness, headache, lachrymation, burning sensation in eyes, nausea and anorexia, etc, were much more in the exposed workers. No cases of clinical poisoning attributable to occupational exposure to pesticides were reported by the workers.

Antiarrhythmic drug therapy in survivors of prehospital cardiac arrest: comparison of effects on chronic ventricular arrhythmias and recurrent cardiac arrest.

We studied the long-term effects of membrane-active antiarrhythmic agents on chronic ventricular arrhythmias in patients who have survived prehospital cardiac arrest. Among 16 patients treated with a dose-adjusted, plasma level-monitored antiarrhythmic regimen, eight have survived for longer than 12 months and eight have had recurrent cardiac arrests (RCAs). Monthly Holter monitor tapes (HM) recorded during the 4 months before the eight RCAs were compared with monthly HM tapes matched for time of entry and duration of follow-up in the eight patients who did not have RCAs. Transient or persistent complex ventricular ectopic depolarizations (VEDs) have been recorded on 47 of the 63 monthly HM tapes (75%). The difference between VEDs in the RCA patients (mean 153 VEDs/hr, median 19 VEDs/hr) and VEDs in the patients who have not had RCA (mean 122 VEDs/hr, median 8 VEDs/hr) was not significant (p less than 0.2); nor was there a predictable relationship between therapeutic plasma levels of antiarrhythmic agents and the frequency and complexity of chronic asymptomatic VEDs (therapeutic levels--mean 104 VEDs/hr, median 6 VEDs/hr; subtherapeutic levels--mean 184 VEDs/hr, median 21 VEDs/hr). Differences were not significant (p greater than 0.1). In contrast, all eight RCA patients had unstable plasma levels (21 of 31 determinations subtherapeutic) while six of the eight patients who have not had RCA had consistently therapeutic levels (p less than 0.01). Thus, adequate plasma levels of antiarrhythmic agents may protect against RCA, despite failure to suppress VEDs predictably. The apparent dissociation between predictable suppression of chronic VEDs and protection against RCA suggests that clinical effectiveness of these agents may not be best measured by their effect on chronic VEDs.

Laboratory aspects of infant botulism in California.

Infant botulism is the newly recognized form of the disease in which illness results from the production of toxin in the infant's intestines. Between the recognition of infant botulism as a distinct clinical entity in 1976 and the end of 1978, 50 cases were identified in California. The diagnosis of botulism was established by the identification of botulinal toxin in and the isolation of Clostridium botulinum from stool specimens of the affected infants. Thirty cases were type A and 20 were type B. Fecal excretion of toxin and organisms was monitored during hospitalization and after discharge from the hospital. Stools from family members and from 160 age-matched control infants did not contain botulinal toxin. A total of 396 food and drug samples, as well as 159 environmental and miscellaneous items, were examined. None of the foods or drugs tested contained preformed toxin. However, C. botulinum organisms were isolated from the nine samples of honey, five of soil, and one of vacuum cleaner dust.

A cohort study of canine testicular neoplasia.

A prospective epidemiologic study of canine testicular neoplasia was undertaken in the Philadelphia area in 1971, with the cooperation of private veterinary practitioners. By the end of 1975, 938 dogs had been monitored for an average of 2 years. The cohort consisted of 609 cryptorchid and 329 age- and breed-matched controls. The incidence of testicular neoplasia in the cryptorchid subcohort was 12.7/1,000 dog-years at risk. Testicular neoplasms did not develop in controls. A large proportion of the dogs were below the average age at onset for this neoplasm. Among dogs over 6 years of age, the incidence was 68.1/1,000 dog-years at risk. The incidence of Sertoli cell tumors and seminoma was approximately twice as high in dogs with unilaterally retained inguinal testicles as in abdominal cryptorchids. Sertoli cell tumors developed in 10 dogs and seminoma developed in 6. One half of the testicular neoplasms that developed did so within the first year of observation. This study demonstrated the feasibility of conducting prospective epidemiologic studies of canine diseases with the assistance of practicing veterinarians.

Immune monitoring protocol for patients with carcinoma of the head and neck. Preliminary report.

Numerous investigators have observed a depression of cell-mediated immunity in patients with carcinoma of the head and neck using a variety of in vitro and in vivo assays. This report presents the data obtained when a group of head and neck cancer patients were evaluated for reactivity in an in vitro lymphocyte blastogenesis assay using polyclonal mitogens and specific antigens, numbers of peripheral blood T-lymphocytes, and levels of circulating immune complexes. Such an immunological monitoring protocol revealed a depressed reactivity of the cancer patients in the lymphocyte blastogenesis assay when compared to normal age-matched controls. We also observed that 75% of these patients had circulating soluble immune complexes in their sera before and after therapy. These preliminary data indicate that further research is needed to examine the potential role of soluble immune complexes in modulating the host's immune response.

A retrospective study of induction of labour.

The labour, delivery and state of the newborn were compared retrospectively in a group of women who had labour induced and a group who started labour spontaneously. There were 200 women at term in each group, individually matched for age, parity and social class and with no medical or obstetric complications prior to labour. The induced group showed a higher incidence of epidural anaesthesia, fetal monitoring and operative delivery. Sixty had forceps deliveries and five had Caesarean sections compared with two forceps deliveries and no Caesarean sections in the 'spontaneous onset' group. The higher incidence of operative deliveries in the induced group was not fully explained by the excess of epidurals and fetal monitoring received. More of the babies born after an induced labour had endotracheal intubation during resuscitation.

Retrospective study of intellectual development in children treated for acute lymphoblastic leukaemia.

Nine younger children (mean age 6-3 years) and 6 older children (mean age 9-0 years), previously treated for acute lymphoblastic leukaemia by cranial irradiation and subsequently by 2 or 3 years of chemotherapy, were assessed in terms of intellectual development in relation to 15 controls, matched individually for age, sex, and social background. All children were functioning within a normal range. The older group of children performed as well as their matched controls in all tasks. However, the younger group tended to perform somewhat below their matched controls, and this applied especially to tasks measuring quantitative, memory, and motor skills, but not to language tasks. It is concluded that there is a continual need to monitor the development of children treated for leukaemia, especially when diagnosed in the 2- to 5- year age range.

Automatic real time arrhythmia monitoring in the intensive coronary care unit.

A prospective study was carried out to evaluate accuracy of a real time computer system for arrhythmia monitoring in a coronary care unit. QRS complexes in 57 continuously recorded 30 minute electrocardiographic rhythm strips from 30 patients were classified by the computer. Blinded interpretation of each beat was made by a cardiologist. A total of 146,638 QRS complexes were classified during the monitoring period of 1,710 minutes. The accuracy rate of computer detection was 99.94%. During this period 67 artifacts were identified as beats. The computer correctly identified 5,467 of 5,729 ventricular premature beats (accuracy of detection rate 95.46%). The incidence rate of false positive diagnosis of beats other than ventricular ectopic beats was 0.1%. The rate of computer accuracy in detecting ventricular premature beats was 93.33% in two patients with atrial fibrillation. In individual patients, computer interpretation did not deviate from the cardiologist's interpretation by more than 1 beat/min. The rate of computer accuracy in detecting supraventricular premature beats was lower (82.45%). The distinctly improved accuracy of computer monitoring of ventricular arrhythmia in a coronary care unit reported is the result of a new algorithm. This approach combines major elements of cross correlation of QRS signals as well as grouping of complexes into families. Normal and abnormal templates are stored and newly detected QRS complexes are matched. The program appears to be sufficiently accurate to warrant further applications.

Rattlesnake bites: current concepts.

The management of snake bites once the patient reaches the hospital should be to obtain the necessary blood parameters (type and cross-matched blood, complete blood count, platelets, PT, PTT, fibrinogen and fibrin split products, electrolytes and calcium), to evaluate the fang marks and the neurovascular status of the involved extremity and to monitor systemic signs and symptoms. These steps are extensively described in the literature, and are commonly agreed upon. We then start intravenous antivenom, after appropriate skin testing for horse serum allergy, beginning with 4--5 vials (8--10 in children) over the initial 30--60 minutes and titrating to cessation of the progression of the toxic signs. Concomitantly, we measure intracompartmental and subcutaneous tissue pressure in all clinically suspected areas. If intracompartment pressures are less than 30 mm Hg, surgical intervention is not necessary; antivenom is continued as necessary and the wick catheter measurements are repeated if indicated. If pressures are greater than 30 mm Hg,immediate surgical decompression is advisable.

Erythrocyte membrane abnormalities in Duchenne muscular dystrophy monitored by saturation transfer electron paramagnetic resonance spectroscopy.

Saturation transfer electron paramagnetic resonance and the spin label 2-(3-carboxypropyl)-4,4-dimethyl-2-tridecyl-3-oxazolidinyloxyl were used to study erythrocytes from patients with Duchenne muscular dystrophy or Becker syndrome and from age-matched normal boys. There were significant differences in the spectral intensities of erythrocytes from Duchenne patients when compared to controls. Spectral intensities increased with time in the former; no such change was observed in the latter. Saturation transfer electron paramagnetic resonance spectra of erythrocytes from patients with Becker syndrome were significantly different from those from Duchenne patients but were not significantly different from normals. These observations suggest the possible usefulness of these techniques in the differential diagnosis of Duchenne muscular dystrophy. Spin label concentration spectral studies suggest that the observed spectral differences between Duchenne patients and controls were due to differential spin exchange phenomena.

Radioimmunoassay of 17 alpha-hydroxyprogesterone in saliva, parotid fluid, and plasma of congenital adrenal hyperplasia patients.

We report a radioimmunoassay sensitive enough to determine 17 alpha-hydroxyprogesterone concentrations in 200 microliter of parotid fluid or mixed whole saliva. Because the correlation of concentrations in matched samples of parotid fluid and saliva was excellent (r = 0.98), we exclusively used saliva, which is easier to collect, in later studies. The assay is specific; saliva samples assayed with and without thin-layer chromatographic purification showed no significant difference. The assay is also precise, and has a lower limit of sensitivity of 4 pg per assay tube. In 14 patients having congenital adrenal hyperplasia from a C21-hydroxylase enzyme deficiency, all of whom were receiving cortisol replacement therapy, the range in 17 alpha-hydroxyprogesterone concentrations observed in saliva (67-26,300 pmol/L) was about 20-fold that seen in 32 healthy children (90-1520 pmol/L). The close correlation (r = 0.91) between 17 alpha-hydroxyprogesterone concentrations in matched samples of saliva and plasma from these patients indicates that determination of steroids in saliva could well replace determination in plasma. This concept is supported by 17 alpha-hydroxyprogesterone concentrations monitored throughout 24 h from one patient and following stimulation with synthetic corticotropin in another patient.
