Ganciclovir has been shown to be carcinogenic, teratogenic, and gonadal toxic in animal models. Mice treated with ganciclovir experienced an increase in the incidence of tumors of the preputial gland (males), harderian gland (males), forestomach (males and females), ovaries (females), uterus (females), mammary gland (females), clitoral gland (females), vagina (females), and liver (females). While the preputial and clitoral glands, forestomach, and harderian glands of mice do not have human counterparts, ganciclovir is considered a potential carcinogen in humans. Animal data indicate that administration of ganciclovir causes inhibition of spermatogenesis and subsequent infertility, possibly due to inhibition of rapidly dividing cell populations including spermatogonia. In the animal models, these effects were reversible at lower doses and irreversible at higher doses. In both male and female mice, ganciclovir has been shown to cause decreased fertility. Gonadal toxicity in rats, mice, and dogs included testicular atrophy in males and, more variable, ovarian atrophy in females. There are no data in humans that demonstrate these effects following treatment with ganciclovir. This study seeks to formally establish the overall sexual development, cancer incidence, and pubertal status of those study subjects who previously received six weeks of ganciclovir as they now approach puberty. The original study was performed from 1986 to 1991, and therefore subjects who were enrolled are now nine to fourteen years of age.
A process for the production of nanocrystals or amorphous nanoparticles of actives (nanomaterials), especially from the peels of grapes. A dispersion of a micrometer-sized material in a solution of surfactant or a steric stabilizer is first provided. The macrosuspension is then stirred for at least 1 minute at a rotational speed above 500 rpm using a rotor-stator mixer. The stirred mixture is passed through a jet stream or piston-gas type high pressure homogenizer. The nanomaterials produced can be incorporated into formulations for use as nutraceutical, nutritional supplement, or as supportive treatment in medical therapy. The active can be derived from the peels of grapes.
Patients were observed and evaluated daily during the morning care between 08:00 AM - 8:30 AM for a maximum 7 days. The visual scale contrived by (Fader et al.(2003) which is based on International Contact Dermatit Score, was used for graded the severity of IAD. Scoring is is 0-to 4 and when scoring is increased the severity of the IAD increased. To evaluate skin integrity, the perineal skin of the patients was observed every day by researcher and was recorded to the Perineal Skin Integrity Assesment Form. The number of defecation, stool consistency, and the number of care product ( the novel incontinent care product) was observed daily and was recorded to the Patient Observation Form. The main study outcomes was IAD.
The global escalation of obesity has made it a worldwide health concern, notably as a leading risk factor for cardiovascular disease (CVD). Extensive evidence corroborates its association with a range of cardiac complications, including coronary artery disease, heart failure, and heightened vulnerability to sudden cardiac events. Additionally, obesity contributes to the emergence of other cardiovascular risk factors including dyslipidaemia, type 2 diabetes, hypertension, and sleep disorders, further amplifying the predisposition to CVD. To adequately address CVD in patients with obesity, it is crucial to first understand the pathophysiology underlying this link. We herein explore these intricate mechanisms, including adipose tissue dysfunction, chronic inflammation, immune system dysregulation, and alterations in the gut microbiome.Recent guidelines from the European Society of Cardiology underscore the pivotal role of diagnosing and treating obesity to prevent CVD. However, the intricate relationship between obesity and CVD poses significant challenges in clinical practice: the presence of obesity can impede accurate CVD diagnosis while optimizing the effectiveness of pharmacological treatments or cardiac procedures requires meticulous adjustment, and it is crucial that cardiologists acknowledge the implications of excessive weight while striving to enhance outcomes for the vulnerable population affected by obesity. We, therefore, sought to overcome controversial aspects in the clinical management of heart disease in patients with overweight/obesity and present evidence on cardiometabolic outcomes associated with currently available weight management interventions, with the objective of equipping clinicians with an evidence-based approach to recognize and address CVD risks associated with obesity.
OBJECTIVE: To determine the frequency of chromosomal aberrations in chorions after a miscarriage. The second was to examine selected euploid chorions using a next-generation sequencing (NGS) panel designed to assess 43 genes associated with pregnancy loss.
MATERIALS AND METHODS: The 1244 chorions were tested by targeted quantitative fluorescent PCR (QF-PCR, 827 chorions) and microarray-based comparative genomic hybridization (aCGH, 417 chorions). Then, 9 euploid chorions were examined using a designed NGS panel.
RESULTS: Trisomies were the most common chromosomal aberration identified in the spontaneous miscarriage samples. The second chromosomal abnormality in the aCGH group and the third most common in the QF-PCR group was monosomy X. Structural aberrations were the third most common aberration in the samples screened by aCGH (7.7% of chorions). In 19% of 647 couples who submitted chorions for analysis after pregnancy loss, the chromosomal abnormality in the chorion originated from a woman with a balanced chromosomal rearrangement. This discovery was statistically significant compared to patients with normal chorions. Using the designed NGS panel, we identified a potentially pathogenic de novo variant in the F5 gene in two euploid chorions. Additionally, among the patients who experienced miscarriages and were screened using the NGS panel, we identified variants in the MDM, ACE, and NLRP2 genes that could be associated with a predisposition to pregnancy loss.
CONCLUSION: Numerical aberrations are the most common cause of miscarriages, but structural chromosomal aberrations also account for a significant proportion of abnormal results. Our findings indicate that couples with structural chromosomal abnormalities in material post-miscarriage are at increased risk of carrying balanced chromosomal abnormalities. Moreover, NGS-based analyses can uncover previously unidentified causes of miscarriages in the chorionic villi.
Described herein is a chelator for radiolabels (e.g., 89Zr) for targeted PET imaging that is an alternative to DFO. In certain embodiments, the chelator for 89Zr is the ligand, 3,4,3-(LI-1,2-HOPO) (“HOPO”), which exhibits equal or superior stability compared to DFO in chemical and biological assays across a period of several days in vivo. As shown in FIG. 1, the HOPO is an octadentate chelator that stabilizes chelation of radiolabels (e.g., 89Zr). A bifunctional ligand comprising p-SCN-Bn-HOPO is shown in FIG. 4 and FIG. 5. Such a bifunctional ligand can eliminate (e.g., 89Zr) loss from the chelate in vivo and reduce uptake in bone and non-target tissue. Therefore, the bifunctional HOPO ligand can facilitate safer and improved PET imaging with radiolabeled antibodies.
Although total hip or knee joint replacement is beneficial in treating severe hip or knee osteoarthritis, a significant number of patients take longer to recover in the hospital or have a non-optimal quality of life after the surgery. These patients often have difficulties in accomplishing basic essential everyday tasks such as walking and stair climbing, both shortly and long after surgery. It has been previously shown through research that difficulties to do basic tasks before surgery delays recovery and negatively affects long-term function. It has also been shown that these difficulties are associated with reduced strength in hip or knee muscles present before surgery, caused by lack of activity of patients. This study will determine if a hip or knee muscle strengthening exercise program accomplished before surgery can improve hospital recovery, capacity to accomplish basic activities, and quality of life two days, six weeks and six months after joint replacement surgery. If this exercise program is shown to be beneficial, it will be easily used by patients when waiting for their surgery.
7-hydroxy-cannabidivarin (7-OH-CBDV) for use as a medicament, in particular in the treatment of epilepsy, is provided. 7-hydroxy-cannabidiol (7-OH-CBD) for use in the treatment of epilepsy is also provided. 7-OH-CBDV and 7-OH-CBD may be used in combination for use in the treatment of epilepsy. 7-OH-CBDV and/or 7-OH-CBD may be used in combination with one or more concomitant anti-epileptic drugs (AEDs), preferably selected from the group consisting of clobazam, levetiracetam, topiramate, stiripentol, Phenobarbital, lacsamide, valproic acid, zonisamide, perampanel and fosphenytoin. Preferably the dose of 7-OH-CBD and/or 7-OH-CBDV is between 1 and 2000mg/kg. When the 7-OH-CBD is used in combination with 7-OH-CBDV, the 7-OH-CBD may be formulated for administration separately, sequentially or simultaneously with the 7-OH-CBDV, or the combination may be provided in a single dosage form.
The da Vinci® Robotic Surgical System (Intuitive Surgical, Inc., Sunnyvale, CA) being evaluated in this pilot study consists of 3 basic components: a surgeon's console, articulated mechanical arms and sterilizable instruments. The console includes a computer, video monitor and instrument controls, and is located in the operating room adjacent to the operating room table. The console is connected via computer to the mechanical arms holding the endoscope (surgical TV camera) and sterile surgical tools (e.g., forceps, scissors, electrocautery, etc.). These arms are located immediately adjacent to the patient on the operating room table. The surgeon sits at the console and controls the position and movement of the arms and surgical tools. The design of these tools is based upon well-established, commonly used surgical instruments. The da Vinci® Robotic Surgical System (Intuitive Surgical, Inc., Sunnyvale, CA) is a "manual image-guided surgery" system that is computer enhanced rather than "computer guided robotic surgery" in which the surgeon programs the computer to do the surgery and the robot does the surgery (also known as a "milling" device).22 Use of the da Vinci® Robotic Surgical System (Intuitive Surgical, Inc., Sunnyvale, CA) in the aforementioned configuration in fact facilitates an exact translation of the surgeon's hand and finger movements at the console to precise and tremor-free movements of the arms and instruments.
Cervical cancer screening has reduced morbidity and mortality in many countries, but efforts to optimize screening modalities and schedules are ongoing. Using data from a randomized trial conducted in British Columbia, Canada, in conjunction with a provincial screening registry, Gottschlich and colleagues demonstrated that the estimated risk for precancerous disease (cervical intraepithelial neoplasia grades 2 or worse) at 8 years following a negative human papillomavirus (HPV) test was similar to the current standard of care (Pap testing after 3 years). The study supports extending screening intervals for those with a negative HPV test beyond currently recommended 5-year intervals. In an ideal world, the resources saved through less frequent routine cervical screening could be redirected to increasing screening uptake and follow-up of abnormalities to improve equity in cervical cancer prevention. However, implementation of extending screening intervals remains less than straightforward in settings with fragmented healthcare systems that lack information systems to support patient call/recall, such as the United States. To achieve the full promise of primary HPV testing, stakeholders at every level must commit to identifying and addressing the diverse spectrum of barriers that undergird existing inequities in care access, appropriately resource implementation strategies, and improve health information systems. See related article by Gottschlich et al., p. 904.

The goal of this study is to compare the capabilities of two novel imaging techniques: conventional 'thermally' polarized perfluorinated gases (perfluoropropane, or PFP) mixed with oxygen, and hyperpolarized xenon (129Xe) mixed with N2 to detect changes in lung ventilation using magnetic resonance imaging (MRI). Although considerable work has been done internationally with hyperpolarized xenon MRI, the low availability and high cost of this technique is limiting. Perfluorinated gas MRI is an alternative that may in fact be a suitable, simpler alternative. PFP is commercially availability in large quantities, which allows multiple breath studies and thus provides the ability to analyze gas wash-in and wash-out kinetics. These endpoints may improve the investigators ability to detect ventilation abnormalities beyond the traditional "ventilation defect percentage" parameter obtained with 129Xe MRI. The commercial availability of PFP and lack of need for onsite hyperpolarization may also facilitate the transfer of this technology to other centers for the conduct of multicenter studies. The investigators hypothesize that 19F MRI will not be inferior to hyperpolarized xenon MRI in detection of ventilation defect percentages (VDP).
Engineered nanoscale multicomponent particles are introduced and are called "quants." Methods and apparatuses for producing such multicomponent nanoparticles are provided. A single quant can be manufactured to contain a variety of different internal component molecules. Likewise, a plurality of such quants may be manufactured wherein the plurality of quants are suspended in an aqueous solution. Typically, quants are produced in quantity and concentration adequate to support human scale therapeutics. In some embodiments, millions or billions of quants are suspended in a volume of aqueous solution for delivery to a patient. When manufactured to the same specification, the plurality of quants are uniform in size, uniform in chemical composition, and therefore uniform in functionality. Functional uniformity is an essential aspect of quants, manifested in design and production. By controlling the variables of manufacture, such as particle size and composition, and by redefining a drug dose as the measured number of quants delivered (as opposed to measuring a drug dose by the mass of its active ingredient), the performance of these nanoparticle-based drugs introduce significant efficiencies and much higher value products to the expanding therapeutics market.
BACKGROUND: Cardiovascular diseases (CVDs) pose significant global health challenges, with genetics increasingly recognised as a key factor alongside traditional risk factors. This presents an opportunity for general practitioners (GPs) to refine their approaches.
OBJECTIVE: This article explores the impact of genetics on CVDs and its implications for GPs. It discusses monogenic disorders like inherited cardiomyopathies and polygenic risks, as well as pharmacogenetics, aiming to enhance risk assessment and personalised care.
DISCUSSION: Monogenic disorders, driven by single gene mutations, exhibit predictable inheritance patterns, including inherited cardiomyopathies and channelopathies such as Long QT syndrome. Polygenic risks involve multiple genetic variants influencing CVD susceptibility, addressed through polygenic risk scores for precise risk assessment. Pharmacogenetics tailor drug interventions based on genetic profiles, though challenges like accessibility and ethical considerations persist. Integrating genetics into cardiovascular care holds promise for alleviating the global CVD burden and improving patient outcomes.
AIM: Sudden cardiac arrest is a significant cause of death worldwide. Good quality cardiopulmonary resuscitation increases patients' survival. Manual cardiopulmonary resuscitation is often ineffective as rescuers may experience physical and mental fatigue. Mechanical cardiopulmonary resuscitation devices are designed to address this issue, providing an automated approach for high-quality resuscitation. In the present comprehensive umbrella review we summarize current evidence on mechanical devices.
METHODS: We searched systematic reviews on mechanical devices in MEDLINE/PubMed. Effect estimates were obtained from original reports, including 95% confidence intervals and p values, when applicable and available, focusing on return of spontaneous circulation, survival to discharge or 30 days, survival with good neurological outcome, and resuscitation-related injuries.
RESULTS: From 21 potentially pertinent publications, we shortlisted 10 reviews, each including between 5 and 22 studies. AutoPulse, LUCAS, and LUCAS-2 were among the investigated devices. Most reviews concluded toward mechanical devices being similar or better than manual resuscitation for return of spontaneous circulation and 30-days survival. Regarding survival with good neurological function, some reviews lacked data, while the remaining ones reported similar results or worse outcomes in patients undergoing mechanical resuscitation. Focusing on resuscitation-related injuries, data were limited or conflicting with one review reporting higher rates of injuries with mechanical devices, and two others suggesting similar outcomes.
CONCLUSIONS: Manual and mechanical cardiopulmonary resuscitation appear to be similar in terms of return of spontaneous circulation and short-term survival. Mechanical devices appear to be associated with higher resuscitation-related injuries, while there are conflicting data in terms of survival with good neurological outcomes. A comprehensive and large dedicated randomized trial is urgently needed.

INTRODUCTION: Clinical understanding of primary progressive aphasia (PPA) has been primarily derived from Indo-European languages. Generalizing certain linguistic findings across languages is unfitting due to contrasting linguistic structures. While PPA patients showed noun classes impairments, Chinese languages lack noun classes. Instead, Chinese languages are classifier language, and how PPA patients manipulate classifiers is unknown.
METHODS: We included 74 native Chinese speakers (22 controls, 52 PPA). For classifier production task, participants were asked to produce the classifiers of high-frequency items. In a classifier recognition task, participants were asked to choose the correct classifier.
RESULTS: Both semantic variant (sv) PPA and logopenic variant (lv) PPA scored significantly lower in classifier production task. In classifier recognition task, lvPPA patients outperformed svPPA patients. The classifier production scores were correlated to cortical volume over left temporal and visual association cortices.
DISCUSSION: This study highlights noun classifiers as linguistic markers to discriminate PPA syndromes in Chinese speakers.
HIGHLIGHTS: Noun classifier processing varies in the different primary progressive aphasia (PPA) variants. Specifically, semantic variant PPA (svPPA) and logopenic variant PPA (lvPPA) patients showed significantly lower ability in producing specific classifiers. Compared to lvPPA, svPPA patients were less able to choose the accurate classifiers when presented with choices. In svPPA, classifier production score was positively correlated with gray matter volume over bilateral temporal and left visual association cortices in svPPA. Conversely, classifier production performance was correlated with volumetric changes over left ventral temporal and bilateral frontal regions in lvPPA. Comparable performance of mass and count classifier were noted in Chinese PPA patients, suggesting a common cognitive process between mass and count classifiers in Chinese languages.
Our aims were to evaluate changes in body characteristics, milk yield and milk constituents as well as to determine the relationship between the thermal environment and production characteristics during the first lactation of dairy Gyr cows managed on pasture. Between 2013 and 2015, forty-five primiparous dairy Gyr cows were evaluated from prepartum to 10 months of lactation in Southeast of Brazil. Body weight, body condition score (BCS), subcutaneous fat thickness (SFT), milk yield (305 d), and milk constituents were collected monthly and progesterone was collected weekly. Additionally, we determined the temperature humidity index (THI) based on microclimate data. Overall, the cows lost body weight until six months of lactation and there was a progressive decrease in BCS, SFT, milk yield and milk lactose as the months in lactation progressed. In contrast, there was an increase in milk fat, milk protein and milk solids. The thermal environment did not pose a consistent heat challenge, nevertheless, we found a positive correlation between the average THI two days before milk collection with milk yield, fat and lactose contents, but in contrast a negative correlation was found with total solids and protein. In conclusion, the THI and months of lactation affected the yield and constituents of milk. However, more studies are necessary to understand the impacts of body characteristics and thermal environment on yield and milk constituents throughout the productive life of Gyr dairy cows.
Patients will be treated with hypofractionated radiotherapy with or without temozolomide (according to the local standard and physician's decision). Radiotherapy and treatment with temozolomide is regarded as standard therapy and not part of the intervention. In case of chemoradiotherapy temozolomide will be applied according to the standard of the participating trial center. Use of antiemetic and infection prophylaxis will be at the discretion of the investigator. Late TTFields treatment will start 4 weeks after the end of radiotherapy.
