Tobacco Cessation Interventions in Non-Respiratory Cancers: A Systematic Review With Meta-analysis of Randomized Controlled Trials.

BACKGROUND: Considering the high rates of persistent tobacco use, effective cessation interventions are needed for cancer patients and caregivers. Despite the need, there is a significant lack of research on tobacco cessation, especially for non-respiratory cancers (breast, prostate, colorectal, cervical, and bladder cancer). PURPOSE: The objective was to evaluate tobacco use and tobacco cessation interventions among patients and caregivers for non-respiratory cancers. METHODS: Randomized controlled trials assessing tobacco cessation interventions were identified. Five electronic databases were searched in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analyses guidelines through July 2023. Studies exclusive to lung, oral, thoracic, and head and neck cancers were excluded. Effect sizes were estimated; risk of bias was assessed. RESULTS: Of 3,304 studies, 17 were included. Interventions included behavioral (n = 6), pharmacotherapy (n = 2), and a combination (n = 9) treatment. Eight studies included a health behavior model; mean behavioral change techniques were 5.57. Pooled magnitude of the odds of cessation was positive and significant (odds ratio = 1.24, 95% confidence interval [Lower Limit 1.02, Upper Limit 1.51]) relative to usual care/placebo. Cumulative meta-analysis examined the accumulation of results over-time and demonstrated that studies have been significant since 2020. Two studies included caregivers' who were involved in the provision of social support. CONCLUSIONS: Current interventions have the potential to reduce tobacco use in non-respiratory cancers. Results may be beneficial for promoting tobacco cessation among non-respiratory cancers. There is a considerable lack of dyadic interventions for cancer survivors and caregivers; researchers are encouraged to explore dyadic approaches.

We aimed to understand effective ways for cancer patients and caregivers to quit using tobacco. We focused on non-respiratory cancers (cancers not related to breathing issues) like breast, prostate, and colorectal cancer. We reviewed 17 randomized controlled trials designed to help people quit tobacco, which included behavioral therapies (e.g., education and counseling), pharmacotherapy (i.e., medicine), and combinations of both. We found that people in these studies quit using tobacco, especially when more than one approach was used. The studies also showed that these approaches have been more successful since 2020. The research highlighted a need for more studies that include both patients and their caregivers together in the quitting process. This approach, called dyadic intervention, could be more effective in supporting patients and their caregivers. Overall, while the current approaches are promising, more research is needed to develop better ways to help cancer patients and caregivers quit smoking for longer.

Cognitive function after concurrent temozolomide-based chemoradiation therapy in low-grade gliomas.

PURPOSE: We sought to evaluate the effects of concurrent temozolomide-based chemoradiation therapy on neurocognitive function in patients with low-grade glioma (LGG). MATERIALS/METHODS: We included adult patients with LGG who were treated postoperatively with radiotherapy (RT) with concurrent and adjuvant temozolomide (TMZ). Patients were evaluated with comprehensive psychometric tests at baseline (prior to RT + TMZ) and at various time intervals following RT + TMZ. Baseline cognitive performance was analyzed by sex, age, education history, history of seizures, IDH mutation status, and 1p/19q codeletion status. Changes in neurocognitive performance were evaluated over time. RESULTS: Thirty-seven LGG patients (mean age 43.6, 59.5% male) had baseline neurocognitive evaluation. Patients with an age > 40 years old at diagnosis and those with an education > 16 years demonstrated superior baseline verbal memory as assessed by HVLT. No other cognitive domains showed differences when stratified by the variables mentioned above. A total of 22 LGG patients had baseline and post RT + TMZ neurocognitive evaluation. Overall, patients showed no statistical difference between group mean test scores prior to and following RT + TMZ on all psychometric measures (with the exception of HVLT Discrimination). CONCLUSION: Cognitive function remained stable following RT + TMZ in LGG patients evaluated prospectively up to 2 years. The anticipated analysis of RTOG 0424 will provide valuable neurocognitive outcomes specifically for high risk LGG patients treated with RT + TMZ.

Quality of life following concurrent temozolomide-based chemoradiation therapy or observation in low-grade glioma.

PURPOSE: Low-grade glioma (LGG) exhibits longer median survival than high-grade brain tumors, and thus impact of our therapies on patient quality of life remains a crucial consideration. This study evaluated the effects of concurrent temozolomide-based chemoradiation (RT + TMZ) or observation on quality of life (QOL) in patients with low-grade glioma. METHODS: We completed a retrospective cross-sectional study of adults with LGG who underwent surgery with known molecular classification from 1980 to 2018. Postoperatively, patients were either observed or received adjuvant concurrent temozolomide-based chemoradiation. EQ-5D and PHQ-9 depression screen were completed before outpatient visits every 2-3 months. Baseline score was defined as ± 30 days within initial operation. RESULTS: Of the 63 patients (mean age 44 ± 17 years, 51% female) with baseline EQ-5D or PHQ-9 depression screen data and at least one follow-up measure, 30 (48%) were observed and 33 (52%) received RT + TMZ. No significant decline was seen in EQ-5D or PHQ-9 scores at 3, 6, 9, 12, and 24 months compared to baseline scores for all patients. At each time point, there was no significant difference between those who were observed or received adjuvant therapy. The linear mixed model estimating PHQ-9 value or EQ-5D index demonstrated that there was no significant difference in PHQ-9 or EQ-5D index between treatment groups (p = 0.42 and p = 0.54, respectively) or time points (p = 0.24 and p = 0.99, respectively). CONCLUSION: Our study found no significant decline in patient QOL or depression scores as assessed by patient- reported outcome measures for patients with low-grade glioma up to 2 years following surgery. We found no difference between RT + TMZ compared to observation during this time frame. Additional follow-up can help identify the longer-term impact of treatment strategy on patient experience.

The Federal Reserve's response to the COVID-19 contraction: An initial appraisal.

We provide an initial assessment of the Federal Reserve's policy response to the COVID-19 contraction. We briefly review the historical episode and consider the standard textbook treatment of a pandemic on the macroeconomy. We summarize and then evaluate the Fed's monetary and emergency lending policies through the end of 2020. We credit the Fed with promoting monetary stability while maintaining that it could have done more. We argue that the Fed could have achieved stability without employing its emergency lending facilities. Although some facilities likely helped to promote general liquidity, others were primarily intended to allocate credit, which blurs the line between monetary and fiscal policy. These credit allocation facilities were unwarranted and unwise.

Naming decline after epilepsy surgery is associated with subjective language complaints.

OBJECTIVE: This retrospective, observational study investigated the relationship between objective naming decline and patient report of subjective decline in language functioning following epilepsy surgery. The role of depression in this relationship was also examined. METHODS: A total of 429 adults with pharmacoresistant epilepsy completed the Boston Naming Test (BNT) and Memory Assessment Clinics Self-Rating Scale (MAC-S) before and after resective surgery. Multiple regression analyses were used to examine the relationship between objective naming decline and subjective language functioning, while controlling for the confounding effect of depression. RESULTS: Individuals who experienced moderate to severe naming decline (≥11 raw points on BNT) following surgery reported a decline in subjective language functioning (p < .001) and endorsed problems with word-retrieval as well as more general semantic abilities. Those who experienced mild naming decline (5-10 raw points) also reported an increase in subjective language problems (p = .006). Complaints in this group were less severe than in those with more marked naming declines and were primarily related to word-retrieval. Both of these relationships remained significant after controlling for the confounding effect of depression (p < .005-.014). CONCLUSIONS: Individuals with epilepsy who experience naming decline following surgery perceive these declines in their daily life, regardless of whether or not they are depressed. Findings support the utilization of risk models to predict naming outcome and the importance of counseling patients regarding the risk for naming decline following surgery.

Pluvicto-Induced 18 F-PSMA PET Bone Flare.

ABSTRACT: A 79-year-old man with a history of metastatic prostate cancer was initially treated with Eligard and switched to relugolix in 2021. The 2022 bone scan presented superscan and extensive osseous metastatic lesions; some had intense PSMA uptake on the initial PSMA PET scan without nodal or visceral metastatic lesions. We treated him with Pluvicto and relugolix. The intermediate PSMA scan demonstrated prominent bone marrow PSMA uptake. However, PSA decreased 58.5%. We hypothesized that the patient might have a bone flare. The final PSMA scan confirmed our hypothesis. Based on our knowledge, this is the first case of Pluvicto-induced bone flare.

The Novel Platinum Analog Dicycloplatin Provides Reliable Growth Inhibition of Urothelial Carcinoma Cells In Vitro.

BACKGROUND/AIM: Platinum-based chemotherapies are a component of standard-of-care regimens for urothelial carcinoma (UC). These nephrotoxic drugs are often dose-limiting, with cisplatin and carboplatin being the most commonly used. Dicycloplatin (DCP) has better solubility and stability, with comparable efficacy and better tolerability. Some suggest the use of DCP as primary treatment for non-muscle-invasive bladder cancer. We exposed UC cell lines to DCP in vitro to assess its efficacy. MATERIALS AND METHODS: A high grade (IV) in vitro UC cell line (TCCSUP) was exposed to varying concentrations of cisplatin (0-600 µg/ml), carboplatin (0-600 µg/ml), oxaliplatin (0-4.0 µg/ml), and DCP (0-350 µg/ml). Grade II-IV cells were exposed to varying concentrations of DCP (0-350 µg/ml) to assess time- and concentration-dependent growth inhibition, and simulate intravesical treatment. Growth inhibition was determined following 24, 48, and 72 h of exposure, using a tetrazolium dye to assess mitochondrial dehydrogenase activity. RESULTS: DCP, cisplatin, and carboplatin effectively achieved >90% cell kill at 72 h. Concentrations of 325 µg/ml DCP, 50 µg/ml cisplatin, and 600 µg/ml carboplatin were sufficient for >90% cell-kill, with cisplatin demonstrating the highest efficacy at the lowest concentration/time intervals. Dose- and time-dependent cell kill were demonstrated at varying concentrations of DCP in grade II-IV cell lines, including cells exposed intravesically. CONCLUSION: In vitro, DCP demonstrates cell-killing efficacy in a time- and concentration-dependent manner in grade II-IV UC cell lines, showing promise for its intravenous, oral, and intravesical use for bladder UC in both primary and adjuvant/neoadjuvant settings.

CHEK2 C1100del mutation associated with papillary renal cell carcinoma type II.

CHEK2 mutations have been noted in bone, brain, breast, colon, lung, thyroid, and prostate cancer. Although now reported in both clear cell and non-clear cell renal cancer, we have not found CHEK2 2 mutations reported in the papillary type II subtype (PRCC). Here, we report a 63-year-old female with a PRCC type II with a concomitant CHEK2 C1100del mutation, who is currently in complete remission three years post tumor resection.

Patient, clinical, surgical, and institutional factors associated with length of stay in scheduled degenerative thoracolumbar spine surgery: National Multicenter Cohort Analysis from the Canadian Spine Outcomes and Research Network.

OBJECTIVE: Length of stay (LOS) is a contributor to costs and resource utilization. The primary goal of this study was to identify patient, clinical, surgical, and institutional variables that influence LOS after elective surgery for thoracolumbar degenerative pathology. The secondary objective was to examine variability in LOS and institutional strategies used to decrease LOS. METHODS: This is a retrospective study of prospectively collected data from a multicentric cohort enrolled in the Canadian Spine Outcomes and Research Network (CSORN) between January 2015 and October 2020 who underwent elective thoracolumbar surgery (discectomy [1 or 2 levels], laminectomy [1 or 2 levels], and posterior instrumented fusion [up to 5 levels]). Prolonged LOS was defined as LOS greater than the median. Logistic regression models were used to determine factors associated with prolonged LOS for each procedure. A survey was sent to the principal investigators of the participating healthcare institutions to understand institutional practices that are used to decrease LOS. RESULTS: A total of 3700 patients were included (967 discectomies, 1094 laminectomies, and 1639 fusions). The median LOSs for discectomy, laminectomy, and fusion were 0.0 (IQR 1.0), 1.0 (IQR 2.0), and 4.0 (IQR 2.0) days, respectively. On multivariable analysis, predictors of prolonged LOS for discectomy were having more leg pain, higher Oswestry Disability Index (ODI) scores, symptom duration more than 2 years, having undergone an open procedure, occurrence of an adverse event (AE), and treatment at an institution without protocols to reduce LOS (p < 0.05). Predictors of prolonged LOS for laminectomy were increased age, living alone, higher ODI scores, higher BMI, open procedures, longer operative time, AEs, and treatment at an institution without protocols to reduce LOS (p < 0.05). For posterior instrumented fusion, predictors of prolonged LOS were older age, living alone, more comorbidities, higher ODI scores, longer operative time, AEs, and treatment at an institution without protocols to reduce LOS (p < 0.05). The laminectomy group had the largest variability in LOS (SD 4.4 days, range 0-133 days). Three hundred fifty-four patients (22%) had an LOS above the 75th percentile. Ten institutions (53%) had either Enhanced Recovery After Surgery or standardized protocols in place. CONCLUSIONS: Among the factors identified in this study, worse baseline ODI scores, experiencing AEs, and treatment at an institution without protocols aimed at reducing LOS were predictive of prolonged LOS in all surgical groups. The laminectomy group had the largest variability in LOS.

Psychometric analysis of five measures of spatial ability.

This study analyzed psychometric properties of five measures of spatial ability on 96 young adults, with supplementary analysis for three of the measures on another sample of 71 young adults. Two measures were taken from the widely cited Kit of Factor-Referenced Cognitive Tests and three other measures were taken from a relatively new source originally intended as laboratory demonstrations. Previous research provided limited information on the psychometric properties of the measures. All five measures yielded adequate reliability and loaded on a single factor. Three measures yielded markedly skewed distributions. Two measures showed clear sex differences with men scoring higher but this difference seemed contaminated by a speed factor; three measures did not show a sex difference. Recommendations for use of the measures in future studies are provided.

First American Cancer Patient to Receive Dicycloplatin (DCP) Chemotherapy Achieves Remission After Seven Weeks of DCP Capsules - A Case Report.

BACKGROUND: The majority of bladder cancer patients experience recurrence. Cisplatin is the standard chemotherapy for muscle-invasive bladder cancer though adverse effects are often severe. CASE REPORT: Intravenous (IV) dicycloplatin (DCP) sustained remission in an American bladder cancer patient for five years. A recurrent mass was observed in July 2021. The patient received DCP capsules for seven weeks with no significant side-effects. Complete blood count with differential and a basic metabolic panel showed no adverse effects of DCP capsules on the bone marrow, liver or renal parameters. Cystoscopy after oral DCP found no evident bladder tumors; cytology was negative for high-grade urothelial carcinoma. CONCLUSION: In this patient, DCP-capsules appeared to be as effective as DCP-IV for achieving bladder cancer remission. Both forms of DCP chemotherapy are convenient, active against several cancer types, with decreased adverse effects compared to cisplatin. Both have been available for treating cancer patients in China. A USA clinical trial of DCP in bladder and other cancers appears warranted.

The memory assessment clinics scale for epilepsy (MAC-E): A brief measure of subjective cognitive complaints in epilepsy.

Objective: The aim of this study was to conduct item reduction of the Memory Assessment Clinics Self-Rating Scale (MAC-S) to create a briefer measure that can be used to quickly evaluate subjective memory complaints in patients with epilepsy. Method: A total of 1333 adults with focal epilepsy completed the original 49-item MAC-S. The sample was randomly split into three subsamples, and a series of analyses (i.e. exploratory factor analysis, confirmatory factor analysis, and item response theory analyses) was conducted to identify an alternative factor structure, with a reduced number of items. A panel of 5 neuropsychologists independently reviewed the final model to assess appropriateness of each individual item as well as the factor loadings and overall factor structure. Final factor titles were subsequently decided as a group. Results: Five factors were identified: Attention, Working Memory, Retrieval, Semantic Memory, and Episodic Memory. The length of the MAC-S was reduced from 49 to 30 items, with items being removed because they failed to load onto any of the factors substantially, or because of poor item discrimination or threshold levels. Conclusions: The Memory Assessment Clinics Scale for Epilepsy (MAC-E), is an updated, brief measure of subjective memory functioning that can be used to efficiently assess relevant, every-day memory abilities in patients with epilepsy within both clinical and research settings.

What clinical psychologists know about evidence-based practice: familiarity with online resources and research methods.

Evidence-based practice (EBP) requires that practitioners routinely access, appraise, and utilize the best available research. We surveyed a representative sample of the Society of Clinical Psychology; 549 psychologists (response rate = 46%) reported their frequency of engaging in EBP when offering psychological services, rated their current knowledge of 12 online research resources, and evaluated their current knowledge of 12 research methods and designs. These psychologists reported, on average, using EBP in 73.1% of their psychological services. With the exception of PsycINFO and MEDLINE, clinical psychologists related low to moderate knowledge of online research resources. By contrast, these psychologists reported considerable knowledge of most research methods and designs, except for odds ratios and structural equation modeling. Psychologists' theoretical orientation, clinical experience, and employment setting predicted knowledge of both online resources and research designs. We discuss the educational and practice ramifications of these results.

Review of Palliative 223Ra in Metastatic Castration-Resistant Prostate Cancer: Experience at West Virginia University Cancer Center.

The ALSYMPCA trial of the α-emitter 223Ra in symptomatic bone-predominant metastatic castration-resistant prostate cancer (mCRPC) reported a median overall survival (OS) of 14.9 mo, versus 11.3 mo for placebo. However, subsequently reported real-world experience with 223Ra in smaller mCRPC patient cohorts has appeared less successful. We performed a retrospective observational study to review our own 223Ra experience at West Virginia University (WVU). Methods: Demographic, clinical, laboratory, and imaging data were reviewed in all bone-predominant mCRPC patients treated with 223Ra at WVU from 2014 to 2019. The number of bone metastases per patient at the start of treatment with 223Ra was quantified via nuclear bone scans (12 scans, 5 of which also included SPECT/CT), body CT scans (8 scans), and PET/CT scans (4 scans). Standard descriptive statistics were used to study institutional review board-exempted, deidentified patient data. Median survival in ALSYMPCA and WVU patients was compared using a 2-sided, 1-sample log-rank test based on the exponential distributions. The primary endpoint was patient OS after initiating 223Ra. Results: Twenty-four patients received 98 infusions of 223Ra; 83% of these patients were referred from outside WVU. Before the first infusion, all 24 had received androgen deprivation therapy. In total, 73 sequential combinations of androgen deprivation therapy were used, 68 of which (93%) preceded the first 223Ra infusion. Also, before 223Ra, 19 (79%) patients had received docetaxel and 19 (79%) had received 33 courses of radiation, 24 of which targeted nonprostatic sites. Eleven patients (46%) completed all 6 planned 223Ra infusions; 13 (54%) stopped early because of clinical deterioration. As of August 2020, only 1 patient remained alive after completing 6 cycles of 223Ra. Median OS from the first 223Ra infusion to the last follow-up or death was 8.3 mo (range, 0-44 mo)-nearly 50% less than the ALSYMPCA median survival of 14.9 mo (P = 0.01). Compared with ALSYMPCA, more WVU patients received bisphosphonates and docetaxel, more had an Eastern Cooperative Oncology Group performance status of at least 2, more used opiates for pain, more had a greater bone metastasis burden by imaging, and more had lower hemoglobin, albumin, alkaline phosphatase, and prostate-specific antigen levels. Conclusion: Although the science supporting the development and clinical use of 223Ra is compelling, optimal clinical benefit will likely require earlier referral for 223Ra, before patients have exhausted most conventional therapies. At WVU, we found that practically all our referred patients had androgen deprivation therapy, radiation, and cytotoxic therapy before starting 223Ra. We continue to offer 223Ra therapy to patients with symptomatic bone-predominant mCRPC but are encouraging earlier patient referral.

Low-back pain after lumbar discectomy for disc herniation: what can you tell your patient?

OBJECTIVE: Lumbar discectomy (LD) is frequently performed to alleviate radicular pain resulting from disc herniation. While this goal is achieved in most patients, improvement in low-back pain (LBP) has been reported inconsistently. The goal of this study was to characterize how LBP evolves following discectomy. METHODS: The authors performed a retrospective analysis of prospectively collected patient data from the Canadian Spine Outcomes and Research Network (CSORN) registry. Patients who underwent surgery for lumbar disc herniation were eligible for inclusion. The primary outcome was a clinically significant reduction in the back pain numerical rating scale (BPNRS) assessed at 12 months. Binary logistic regression was used to model the relationship between the primary outcome and potential predictors. RESULTS: There were 557 patients included in the analysis. The chief complaint was radiculopathy in 85%; 55% of patients underwent a minimally invasive procedure. BPNRS improved at 3 months by 48% and this improvement was sustained at all follow-ups. LBP and leg pain improvement were correlated. Clinically significant improvement in BPNRS at 12 months was reported by 64% of patients. Six factors predicted a lack of LBP improvement: female sex, low education level, marriage, not working, low expectations with regard to LBP improvement, and a low BPNRS preoperatively. CONCLUSIONS: Clinically significant improvement in LBP is observed in the majority of patients after LD. These data should be used to better counsel patients and provide accurate expectations about back pain improvement.

Smoking is associated with adrenal adenomas and adrenocortical carcinomas: a nationwide multicenter analysis.

MICROABSTRACT: The effect of smoking on adrenal cancer is poorly understood. A clear association of adrenal adenoma and adrenocortical carcinoma with smoking among the United States population is observed. This association points to the possibility of environmental carcinogenic and/or lifestyle factors contributing to adrenal cancer formation. Our results support the association of tobacco use with adrenal adenomas and adrenal cortical carcinoma. BACKGROUND: Smoking has been suggested as a risk factor for adrenal cortical carcinoma (ACC), but this hypothesis has only been inferred from a single study using all types of adrenal cancers including pheochromocytoma, neuroblastoma, as well as ACC. Given the high rate of tobacco use in West Virginia, we hypothesized that smoking might contribute to increased prevalence of ACC. MATERIALS AND METHODS: De-identified institutional review board-exempted records were analyzed in the Surveillance, Epidemiology, and End Results (SEER) Program from 2001-2016 and in patients from the United States nationwide, multicenter TriNetX database of 41,063,707 patients from 2008-2018. In addition, the state-level ratio of smoking to ACC prevalence was computed in all 50 states using data from SEER and the Center for Disease Control. West Virginia Health System data from 2008-2018 was extracted to confirm population-level findings. Melanoma was used as a cancer control in both databases. RESULTS: 6,946 ACC cases were identified. West Virginia had the highest smoking rate and the second highest rate of ACC. A significant association was found between smoking and ACC (Pearson correlation coefficient r = 0.4887, p=.0004). From 2008 to 2018 using TriNetX, 846 ACC and 36,434 AA were extracted. Both adrenal neoplasm cohorts had increased prevalence of tobacco use compared with melanoma controls, where 23.5% were smokers compared to 36.4% and 33.9% in the ACC and AA groups, respectively (p<0.0001 each). CONCLUSION: To our knowledge, this is the first United States population-based study supporting smoking as a risk factor for adrenal carcinogenesis and ACC.

Psychotherapy preferences of laypersons and mental health professionals: Whose therapy is it?

What do patients prefer in their psychotherapy? Do laypersons and mental health professionals (as patients) want the same, or different, things? The authors systematically examined patients' psychotherapy preferences and quantitatively compared two samples of laypersons (N = 228, 1,305) with one sample of mental health professionals (N = 615) on the four dimensions of the Cooper-Norcross Inventory of Preferences: Therapist Directiveness Versus Client Directiveness, Emotional Intensity Versus Emotional Reserve, Past Orientation Versus Present Orientation, and Warm Support Versus Focused Challenge. On average, laypersons wanted therapist directiveness and emotional intensity. Robust differences were found between laypersons' and professionals' preferences on these two dimensions: Mental health professionals wanted less therapist directiveness than did laypersons (gs = 0.92 and 1.43 between groups) and more emotional intensity (gs = 0.49 and 1.33). Women also wanted more warm support than men (gs = 0.40 and 0.57). These findings suggest that psychotherapists should be mindful of their own treatment preferences and ensure that these are not inappropriately generalized to patients.

Adverse Effects Profile of Dicycloplatin (DCP) Offers Chemotherapeutic Advantage Over Cisplatin and Carboplatin.

BACKGROUND/AIM: Platinum-based chemotherapy often fails due to its severe adverse effects. The aim of this study was to examine the adverse effects profile and efficacy of dicycloplatin and compare them to those of cisplatin and carboplatin. MATERIALS AND METHODS: Cystoscopy surveillance of the first American cancer patient treated with dicycloplatin was performed quarterly. In vitro and in vivo studies were conducted using immunoblotting and flow cytometry to assess immune status of spleen and bone marrow of mice treated with dicycloplatin, cisplatin and carboplatin. RESULTS: The American patient did not suffer clinically significant myelosuppression; dicycloplatin has sustained remission in this patient to date. Experimental studies showed that dicycloplatin is less toxic to bone marrow and spleen of mice than cisplatin and carboplatin. CONCLUSION: Dicycloplatin is a promising drug in cancer chemotherapy with less aggressive side-effects than those typically associated with cisplatin and carboplatin. This is an important therapeutic advantage in cancer chemotherapy. Clinical investigation of dicycloplatin as an alternative to cisplatin or carboplatin is warranted.

Personality factors related to quantitative estimation skill: confirmation and extension.

The relationships of two measures of quantitative estimation skill, computational estimation and numerosity estimation, were examined with the 16 PF Global Factors corresponding to the Big Five personality dimensions in a sample of 80 college students. Correlations of Computational Estimation with the 16 PF scores confirmed findings from a previous study which used the NEO-Five Factor Inventory as a measure of the Big Five, specifically showing that Computational Estimation correlated significantly with the 16 PF's Independence factor. Numerosity Estimation did not correlate significantly with any of the 16 PF Global Factors or with any of the ability measures (Computational Estimation, SAT Verbal, SAT Mathematics, and self-rated mathematics ability) used in the study.
